How to repair the fault of oil press

What is an oil press?

How does it work? What is its main function? It is mainly a transmission method that uses liquid pressure to transmit power and control. At present, it is widely used in spare parts processing, various professions, a variety of product finalization, edge punching, etc. It has many functions, so it has a wide range of applications. When the equipment is used, equipment failure is inevitable. Therefore, the corresponding faults should be repaired in time.

The same components on the oil press of the same type, structure and principle should be installed in the same position. The main purpose is to prove whether the replaced components work reliably. The advantages of replacement method are that the technical level of repairmen is low, and this method can also be used to make accurate diagnosis of equipment faults.

At the same time, during maintenance, it is also necessary to diagnose whether the hydraulic components of the equipment are defective with the help of simple auxiliary parts.

Advantages of LXSHOW fiber laser cutting machine

Advantages of machine fiber laser cutting: 1530 fiber laser Cutting Machine can obtain better cutting quality because of the small laser spot, high energy density and fast cutting speed. The cutting slit of the laser cutting machine fiber 2kw is very thin and narrow, the two sides are parallel and perpendicular to the surface, and the dimensional accuracy of the cutting parts can reach ±0.05mm.

The cutting surface is clean and tidy, and the surface roughness is very low, only tens of microns. Laser cutting can be used as the last process without mechanical processing, and the parts can be used directly. After laser cutting, the width of the heat-affected zone is very small, and the performance of the material near the slit is almost unaffected, and the workpiece has small deformation, high cutting accuracy, good geometry of the slit, and the cross-sectional shape of the slit is relatively regular Rectangle.

High cutting efficiency: Due to the transmission characteristics of the laser, the fiber optic laser cutting machine is generally equipped with multiple numerical control worktables, and the entire cutting process can be fully controlled. The cutting speed is fast, and the material does not need to be clamped during laser cutting, which not only saves tooling fixtures, but also saves auxiliary time for loading and unloading.

Non-contact cutting: There is no contact between the torch and the workpiece during laser cutting, and there is no tool wear. To process parts of different shapes, you only need to change the output parameters of the laser. The laser cutting process has low noise, low vibration and no pollution.

There are many types of cutting materials: Compared with oxyacetylene cutting and plasma cutting, there are many types of laser cutting materials, including metal, non-metal, metal-based and non-metal-based composite materials, leather, wood, and fiber. But for different materials, due to their own thermophysical properties and different absorption rates for lasers, they show different laser cutting adaptability.

6 major elements of choosing a stone cnc router Upload to:08-24 2021

  Stone cnc router are widely used in many industries, but how much do we know about the choice of stone cnc routers? Today, the editor of China will take you to learn about the choice of stone cnc router

  1. To understand the performance and function of the stone cnc router motor, the engraving head motor of the cnc router is also very important, because the engraving head motor is generally not covered by the warranty, and the engraving head motor works continuously for a long time, so if you engrave A bad head motor will also affect the use of the cnc router.

  2. Pay attention to the function of the stone cnc router. The engraving motor of the cnc router has high power and low power. Some cnc routers with low power are only suitable for the processing of materials such as two-color boards, architectural models, small signs, three-dimensional crafts, etc. This technology has been popular for some time, but the engraving power is too small and its application range is greatly affected. The other is a high-power engraving head cnc router, this kind of cnc router is divided into two categories, one is a large-format cutting machine: the format is generally more than one meter, but the accuracy of this kind of cnc router is generally poor; the other The class is an cnc router with moderate format: this kind of cnc router is generally used in fine processing and organic sign production.

  3. In addition, the speed adjustable range of the engraving head motor, the general adjustable speed range is several thousand to 30,000 revolutions per minute. If the speed is not adjustable or the speed adjustable range is small, then the application range of the cnc router is limited. Subject to great restrictions, because different materials must be engraved with different engraving head speeds.

  4. The manufacturing process of the cnc router body: When the high-power cnc router is working, the body must be precise and stable. Therefore, the casting body should be used for long-term high-power engraving to ensure its processing accuracy and stability.

  5. Controllers are generally divided into two categories: the first type of controllers is only used for driving, and all calculation work is done by the computer. When the cnc router is working, the computer is in a waiting state and cannot perform typesetting work. Another type of controller is controlled by a single-board computer or a single-chip computer. This controller is actually a computer, so as long as the cnc router starts to work, the computer can immediately perform other typesetting work, especially when engraving for a long time. The advantages are particularly obvious.

  6. The screw rod and guide rail are also an important part of the stone cnc router. A good screw rod and guide rail are the guarantee of the accuracy and performance of the cnc router when it is used for a long time.

  Generally, when choosing a stone cnc router, we look at these six aspects. It is enough to choose the model that is suitable for your use. For more relevant information, you can continue to pay attention to us. The China editor will update you with more product knowledge. Please look forward to it.

Solution to invalid operation of hydraulic press

1. Wear

The hydraulic valve core, valve sleeve, valve body and other mechanical parts have friction between the movement pairs during use, which makes the size, shape and surface quality of the parts change and fail. These may make the valve fail.

2. Fatigue

Working under long-term variable load, the spring in the hydraulic valve will become soft due to fatigue, shorten the length of the spring, or break completely; the valve core and valve seat will also be cracked, peeled or damaged due to fatigue. The spool of the reversing valve is bent and deformed, which will make it difficult for the reversing action of the valve to proceed normally. The relief valve pilot cone valve (or pilot small ball valve) is not tightly sealed due to wear and cannot be adjusted normally. The wear of the pilot valve of the pressure reducing valve will make the valve work unstable and even unable to regulate the pressure. Fatigue or broken springs on the main slide valve or pilot valve of the relief valve will make the system pressure less than required. If the matching clearance between the valve core and the valve hole is too large, pressure shock will occur. The spool of the overflow valve is bent and deformed or the spring is deformed, which will make the spool move inflexible and cause the system pressure to be unstable.

3. Deformation

When the residual stress of hydraulic valve parts during processing and the external load stress during use exceed the yield strength of the material of the parts, the parts will deform and fail to complete their normal functions. If the spring of the reversing valve of the Hydraulic Press is too soft or short, it will affect the spool working position and normal reset, making the system unable to work normally. Note that improper assembly may also cause deformation of the parts. For example, the valve body deformation caused by the reversing valve assembly screw is tightened too tightly, which may cause the valve core to jam.

4. Corrosion

Excessive water or acidic substances mixed in hydraulic oil will corrode the relevant parts in the hydraulic valve after long-term use, causing it to lose its due accuracy and become invalid. The abrasion or deformation of the valve core of the electromagnetic reversing valve will cause the valve to leak and reduce the efficiency, and the dirt will easily enter the gap or deformation, so that the valve core will be blocked by the gas. The bending and deformation of the spool of the unloading valve will slow down the action of the spool, and make the conversion process of the system from unloading to working pressure or working pressure to unloading slow. The one-way valve of the one-way throttle (speed control) valve is partially worn and the seal is not tight. Part of the oil flow will flow away through the one-way valve, which affects the sensitivity of the speed control.

Innovation changes the future, 3D printing is indispensable-Interview with Mr. Jos Burger, CEO of Ultimaker, a leader in desktop 3D printing

In February of this year, Ultimaker, a global desktop 3D Printing leader, announced that Essentium, eSun and Polymaker have joined the “Ultimaker Materials Alliance Program” (Materials Alliance Program), which will further bring a variety of FFF desktops to more industries 3D printing materials and application selection. Ultimake was established in the Netherlands, with offices in New York, Boston and Singapore, and factories in Europe and the United States.

The global team has more than 400 employees and more than 50 distributors all over the world. It is hard to imagine that a company of this size was founded in 2011. In just a few years, the product categories include 3D printers, materials and software, and application cases are spread across multiple industries, such as construction, aerospace, and automobile manufacturing. “3D Printing World” had the honor to interview Ultimaker CEO Jos Burger to understand how they rose to become a leader in the desktop 3D printing field in a short period of time. The three can form an army, do not forget their original intentions, and are loyal to their mission. Ultimaker was founded by the three founders of Martijn Elserman, Erik de Bruijn and Siert Wijnia, and originated from ProtoSpace Utrecht.

One of the founders, Siert Wijnia, wanted to build a RepRap Darwin 3D printer, but encountered various obstacles in the process. Subsequently, the other two founders joined the research project, and the three gradually formed their own design inspiration, hoping to print the parts they need, no longer limited to the RepRap Darwin 3D printer.

The first prototype “Ultimaker protobox” was born. Then Ultimaker Original was established and released the Do It Yourself kit, hobbyists and technicians can assemble it and use it, and users can also share their experience with the community. After Ultimaker was formally established in 2011, it has gathered a group of talented technical talents. Their mission is to accelerate the world’s transition to local digital manufacturing.

The original intention of their establishment is very simple, that is, to target the desktop 3D printing market. They hope that the desktop 3D printer can become a device that can be seen everywhere, whether it is amateur or professional users, whether in the home or office environment, people can print what they need at any time on demand. Adhering to this initial aspiration and mission, Ultimaker successfully obtained multiple financings from 2016 to 2018, gradually went international, and quickly grew into a new star in the desktop 3D printing field.

Looking at the world, every market is unique. In 2015, Ultimaker officially landed in the North American market, and then their footsteps went to Europe and Asia. Now there are factories in Europe and the United States, and more than 50 distributors worldwide. Talking about the reason for such rapid expansion, Jos Burger said that Ultimaker has been listening to the “voices” from all sides. Before deciding on the next new product, they will fully understand the future trend of the market and the needs of users. Just as before the advent of portable notebooks and smart phones, it is hard to imagine how convenient and fast it is to work and communicate with people today. Before the advent of 3D printing, people have always relied on subtractive manufacturing. The emergence of additive manufacturing has brought more design freedom to the manufacturing industry, and people can use less time and cost to create things that were previously unimaginable. It is this advanced thinking that Ultimaker has launched a variety of desktop 3D printers, materials and software in a short period of time.

Because the needs of users were taken into account during research and development, these products quickly moved to the international market. In the process of continuous advancement, Ultimaker has chosen to set up offices in the United States and Singapore. When talking about why he chose this Southeast Asian country, Jos Burger said that the Southeast Asian market, like China, is a market with unlimited potential. With the transformation and upgrading of China’s manufacturing industry, from labor-intensive to technology-intensive, many large manufacturing companies have moved their factories to Southeast Asia where labor is cheaper, which has promoted the prosperity of Southeast Asia’s manufacturing industry. The Chinese market and the Southeast Asian market have their own characteristics. Ultimaker will encounter different opportunities and difficulties when developing in different markets, but they have never stopped moving forward in the global territory. Each market is unique to them, and the opportunities hidden in them are precious. Promoting the industry to enter the application field, companies are duty-bound. In 2018, 3D printing application cases have emerged one after another, and the number has doubled from the previous year. In order to further promote 3D printing into the application field, Ultimaker launched the “Ultimaker Materials Alliance Program” (Materials Alliance Program). Now more than 60 companies have joined the alliance, including global chemical giants such as BASF and DuPont. Ultimaker is even more practical in this matter. Its 3D printers, materials and software are used by famous companies in all walks of life, including Volkswagen, Ford, Bosch, Airbus and L’Oréal. Ultimaker believes that these application cases are the strongest evidence to prove the value of 3D printing in traditional manufacturing. And corporate decision makers are also gradually changing their thinking. They find that 3D printing technology can bring more flexibility to production processes and products, and efficiency has also improved. Therefore, they increasingly hope that 3D printing can help them accelerate digitalization. Transformation. Different from the initial development of 3D printing technology, people are now more familiar with this technology and easier to accept the changes brought about by this technology. But Ultimaker has never dared to take it lightly in the education market. They always believe that as an important part of this industry, the role played by enterprises is also indispensable.

Although this technology has transitioned from knowledge popularization to application, their official website still provides users with the most basic industry knowledge and case sharing, and users can also share and exchange experiences in the community. For leading 3D printing companies like Ultimaker, 2019 will be a crucial year. As a major player in the field of desktop 3D printing solutions, Ultimaker is paying more and more attention to ISO standards, quality assurance, material certification, workflow integration and IT security. This factor is not only the key to advancing the development of the entire 3D printing industry, but more importantly, to eliminate the ultimate obstacle to the widespread application of 3D printing. In the new year, they will focus on achieving this goal, which is critical to their journey to accelerate the world’s transition to local digital manufacturing. About Jos BurgerJos Burger is currently the CEO of Ultimaker. In more than 20 years of professional career, he has accumulated rich experience in building software and telecommunications companies and their European branches. He has helped Ultimaker become a leader in the desktop 3D printing market with his wealth of knowledge, contacts and experience. His firm belief in FFF 3D printing technology drives him to continuously push Ultimaker into new markets.

Handling and precautions of woodworking cnc router machine cutting tools Upload to:09-07 2021

  The performance of the woodworking cnc router machine itself is important, but the choice of woodworking cnc router machine tools also affects the processing effect and processing efficiency. You get what you pay for, no matter what kind of things we buy, this sentence makes a lot of sense. A good woodworking cnc router machine has high machine configuration and good quality accessories, and the price is definitely high.

  Precautions for loading and unloading of woodworking cnc router machine cutters:

  1. When loading the knife, clean the chuck and pressure cap with gasoline or WD40 cleaning agent.

  2. Put the chuck into the pressure cap, otherwise the tool will not be easy to install. If the chuck is not clamped in the pressure cap, the chuck will be clamped in the motor shaft and cannot be removed when unloading the tool.

  3. Before clamping, pay attention to whether the chuck matches the selected tool, otherwise the tool cannot be tightened.

  4. When clamping the tool, the part of the tool protruding from the chuck should not be too long, otherwise it is easy to produce vibration during the machining process, which will affect the machining quality of the workpiece surface.

  5. When changing the tool, the spindle speed must be zero, that is, the tool is allowed to be disassembled when the spindle is stopped, otherwise serious personal injury accidents may occur.

  6. If you use the presser foot to engrave, you need to use a vacuum cleaner to clean the dust on the presser foot and the spindle, and then install the tool.

  7. In the process of screwing up the pressure cap, be sure to align the pressure cap to the rotor thread, and first screw it in place by hand without any effort.

  8. When unloading the knife, clean up the waste on the pressure cap and rotor shaft before unloading the knife.

  The above is the information about the loading and unloading of woodworking cnc router machine tools and precautions that we introduced for everyone. If you want to know more information about the engraving machine, please call us!

Discussion on the transformation of CNC machine tools

As a large country of machine tools, in order to improve the CNC rate of machine tools, it is a good policy to carry out CNC transformation of normal machine tools. Some developed countries such as Germany, the United States, Japan, etc. attach great importance to the transformation of old machine tools, and have formed a complete transformation system of industry-university-research linkage. Because of the continuous improvement of skills, machine tool transformation has become a permanent issue. China should increase publicity in this regard, and embark on a road of CNC transformation of machine tools that suits China’s national conditions.
1. The meaning of CNC transformation of machine tools
1. Save money. Compared with the purchase of new machine tools, the CNC transformation of machine tools can usually save 60% to 80% of the cost, especially for large and special equipment. Usually large-scale machine tools only need to spend 1/3 of the purchase cost of new machine tools. Even if the structure of the original machine tool is completely modified and upgraded, it only needs to spend 60% of the cost of purchasing a new machine tool and can use the existing foundation.
2. The function is stable and reliable. Because the basic parts of the original machine tool have been aging for a long time, there is almost no stress deformation that affects the accuracy.
3. Improve production power. After the machine tool is transformed by the numerical control, the processing automation can be completed, and the power can be 3~7 times higher than that of the traditional machine tool. For messy parts, the higher the difficulty, the more progress the effect will be. And it is possible to eliminate or use less tooling, which not only saves costs, but also shortens the production preparation cycle.
Second, the plan for the CNC transformation of the machine tool
1. Selection of CNC system
The numerical control system is the center of the machine tool. When selecting, it is necessary to summarize and think about its function, economy and repair service, and try to choose brand-name products. The CNC system is selected according to the structure, function and accuracy of the machined parts to be modified. It is necessary not only to match the functions, but also to reduce the excess CNC functions as much as possible. On the one hand, this can prevent the waste of funds, and on the other hand, it can also prevent the increased failure rate due to the disorder of the CNC system.
There are three main types of current numerical control systems: an open-loop system driven by a stepper motor; a closed-loop numerical control system driven by an asynchronous motor or a DC motor to measure the response of a grating; and a semi-closed-loop numerical control system driven by an AC/DC servo motor driven by an encoder. During the open-loop system driven by a stepper motor, its servo drive equipment is mainly a stepper motor, a power stepper motor, an electro-hydraulic pulse motor, etc. The displacement accuracy of this system is low, but the structure is simple, the debugging and repairing is convenient, the quality is stable and reliable, the cost is low, the anti-interference function is strong, the demand for the ambient room temperature is not high, and the modification is easy to be successful. It is suitable for the transformation of small and medium-sized machine tools with usual precision requirements, and it is also the most widely used one in the current CNC transformation. The closed-loop numerical control system of asynchronous motor or DC motor driving the grating to measure the response has high control accuracy, but it is messier than the open-loop feed system in structure, the workload is large, the cost is also high, and the debugging is difficult, so it is usually not used. The accuracy of the semi-closed-loop numerical control system with AC/DC servo motor driving the encoder response is between the former two. The structure and debugging are simpler than the closed-loop system. It is suitable for the transformation of large and medium-sized machine tools with higher control accuracy requirements.
2. Some mechanical modifications
The numerical control of the machine tool should reach a higher static and dynamic stiffness. For this reason, the friction coefficient between the motion pairs is small, the transmission is free, the power is large, and it is easy to operate and repair.
For CNC lathes, in addition to the original precision, the guide rail should also have outstanding abrasion resistance and small friction resistance. At present, it is mostly used to bond the PTFE soft tape to the original guide rail, which can prevent climbing, and has self-lubricating property, which can improve the life of the guide rail, and has a small workload, short cycle and low cost.
The accuracy of the drive chain is affected by the drive screw and gear pair. The price of sliding screw is low, but it is difficult to satisfy the processing of parts with high precision; the friction loss of the ball screw is small, the transmission power can be more than 90%, the transmission is flexible, the accuracy is high, the life is long, and the motor torque can be reduced. Satisfy the processing needs of higher precision parts.
In order to ensure the transmission accuracy, the gears used on cnc machine tools have a higher level of accuracy than ordinary machine tools, and they must achieve no gap transmission. There are two ways to eliminate the transmission gap of the gear pair: flexible adjustment method and rigid adjustment method. The flexible adjustment method has a messy structure and low transmission stiffness; the rigid adjustment method has high transmission stiffness and a simple structure.
3. Example analysis of CNC transformation of machine tools
Now take an economical CNC lathe as an example to illustrate the key points of the transformation.
1. Choose a digital control system. Imported CNC systems include Fanue from Japan, Siemens from Germany, and MCS-8051 from the United States. The domestic CNC systems mainly include Huazhong CNC and Guangzhou CNC systems. These systems all have functions such as linear interpolation, circular interpolation, car male/inch thread, tool compensation, gap compensation, automatic tool indexing, etc. They are stable in function, moderate in price, simple and intuitive operation panel, with start button, pause button, Single/continuous switch, continuous feed key, emergency stop key, keyboard, display screen, etc. It not only controls the weak current, but also can control the speed of the spindle, the indexing of the tool post, the start and stop and reversing of the spindle, and other auxiliary actions through commands.
2. Ball screw pair transformation. In order to complete the screw-free transmission, the sliding screw of the original machine tool should be replaced with a ball screw pair. This item is not a necessary change. For example, when the accuracy of the machine tool is not high, the transmission gap can be eliminated by pre-tightening the original nut.
3. Stepper motor selection. When the lathe feed transmission is modified, the mechanical transmission mechanism must be dismantled and replaced by a stepping motor to drive the lead screw through a gear or a timing belt and a deceleration to drive the tool post to move. The longitudinal stepping motor is fixed on the bed, and the horizontal stepping motor is fixed on the bed saddle. If the torque of the stepping motor is large enough and the structure permits, the drive mechanism can be decelerated, and the stepping motor is directly connected to the rolling screw.
4. Automatic tool post installation. Replace the tool post of the original lathe with an automatic indexing tool post. The most common type of automatic indexing tool post for horizontal lathes is the spiral four-index tool post. After removing the small carriage, adjust the height of the tool post and install it on the middle carriage. It is directly controlled by the CNC system, with high power and process functions. reliable.
5. Install the photoelectric encoder. In order to ensure that the feed of the stepper motor is matched with the rotation of the spindle during thread processing, the fixed pitch, fixed starting point, multi-start thread and other indexed threads are cut, and an incremental photoelectric encoder is usually installed at the tail of the spindle. When thread cutting, the encoder rotates synchronously with the spindle, and at the same time sends out a pulse signal corresponding to the rotation angle of the spindle to control the longitudinal movement of the tool post.
6. Rail transformation. In order to prevent the feeding parts from crawling, affecting the smoothness of movement and positioning accuracy, two methods can be selected, one is to stick the original guide rail with a soft belt; the other is to change to a rolling guide rail. When the precision requirements of the machine tool are not high, the guide rail is usually not modified.
7. Spindle speed change mechanism. The transformation of spindle speed change usually selects the AC asynchronous motor frequency conversion speed regulation system, and the CNC controls the frequency converter and the frequency converter drives the AC asynchronous motor to complete automatic stepless speed change. In the case of low demand for automation, some of the machine tool spindle speed changes may not be changed, which can greatly reduce the cost of transformation.
4. Issues that should be paid attention to
1. Selection of construction team. The effect of the transformation largely depends on the quality of the construction team and should be paid attention to.
2. On-site debugging. At this stage, the quality should be strictly controlled and preparations for acceptance should be made.
3. Acceptance. Acceptance usually has two contents: (1) Trial cutting of standard samples, and formulating cutting procedures in accordance with the standards. Perform trial cutting with the cooperation of qualified operators and programmers to check whether the machine’s rigidity, cutting force, noise, motion trajectory, and related actions are qualified. (2) Verification of machine tool accuracy. After the transformation, the control accuracy of the machine tool should be checked by comparing the system’s own functions (such as step size, etc.) with standard measuring instruments (such as laser interferometer), so that the data obtained can be used to compensate the position measurement system, thereby improving the accuracy of the machine tool. At the same time, it should be compared with the functions and accuracy of the machine tool before the transformation to obtain a quantitative index difference. The various mechanical function indexes of the machine tool should meet the standard requirements, and the geometric accuracy should be within the specified range.
4. Retention of transformation materials. After the machine tool is transformed, it is necessary to obtain transformation drawings, materials, and transformation records from the construction unit, and collect, organize, and file them. Maintaining the integrity of the data is very important to the stable and stable operation of the equipment in the future.

Reasons for gear pump vibration in four-column hydraulic press

Reason analysis of gear pump vibration in four-column Hydraulic Press:

  • 1. Check whether the gear pump of the four-column hydraulic machine sucks in the oil with bubbles from the oil tank.
  • 2. Check the installation concentricity of the four-column hydraulic pump and the motor. It should be stipulated that the installation concentricity of the pump and the motor should be adjusted.
