Every step of the pipe bending machine mold has an important policy, which requires us to have a professional understanding and knowledge of the common sense of the bending machine mold. How to improve the processing quality of the bending machine mold and the life of the bending machine mold, the technical common sense in this regard, the different. Here is a brief overview of how to improve the use of the bending machine mold.

1. The machining allowance of the tube bending machine evenly distributed ensures stable and high productivity and safe bending process. When the angle is constant, the speed of the bending and the feed rate can also be stably maintained at a higher level. In this way, the mold action and workload change on the bender is small, so the heat and fatigue are less, and then the die life of the bender is improved.

2. One of the most important guidelines for the bending machine mold in the bending process is that in each bending process, the bending machine mold creates a uniform distribution of machining allowance for each bending. That is to say, it is necessary to use bending dies at different angles, and the primary pipe bending machine mold should be as close as possible to the final shape of the mold in each process.

3. In order to obtain the longest life, the pipe bending machine mold should insist on continuous cutting for as long as possible during the bending process. If the bending machine mold enters and exits too much, the life of the bending machine die will be significantly shortened. This will increase the thermal stress and hot fatigue on the cutting edge. It is more advantageous to have a uniform and high temperature in the cutting area than to have a large shake on the modern carbide bender mold.

With the rapid development of China's scientific skills and the application in the pipe bending machinery industry, the scale development of China's pipe bending machinery is constantly experienced, and its quality and skills are gradually in line with international standards. Among the many types of pipe bending machines, the pipe bending machine is also distinguished by its unique advantages, and it is also quite suitable for the purchase of customers. Therefore, the industry of the pipe bending machine is also receiving considerable attention.

The market development of the pipe bending machine is also constantly accelerating, and its development is constantly moving toward the direction of high-speed intelligence. A batch of fully automated pipe bending machines are constantly appearing in front of people, which is also expanding. The market development prospects of the pipe bending machine have also enabled the pipe bending machine to have a better market potential.

About the products of the pipe bending machine, the most popular period is during the holiday season. Its affordable and beautiful outer packaging is very suitable for gifting relatives and friends. Therefore, the festival has become a product of the pipe bending machine, and about it. The development is also inseparable from the bending machine to help. With the approaching of the festival, the producers and industry of such commodities are also catching up with the production to satisfy the market supply during the holiday season. At the same time, they also add the benefits and image propaganda of the company, and believe that they can get better in the future. The launch.

Whether in the automotive parts or furniture production, the use of pipe bending machine is very important, the primary effect of the pipe bending machine is to be able to process the bending into any desired curvature, and the operation is very convenient and safe. . Many pipe bending machine on the market today use microcomputers for production and operation, and the smart chips used also have high sensitivity.

The tube bending machine uses the encoder to control the angle of processing, so the processed elbow is very accurate in angle, which is precisely because it makes it widely used in the profession. However, the biggest disadvantage of the bender in the process of processing is the relatively loud noise, which is the primary reason why it can not be selected in many occupations. How to deal with this problem effectively?

Many manufacturers choose the tube bending machine, not only the quality of the processing, but also the requirements for the comfort of the operation. The domestic bending machine also has requirements for noise, and the power is relatively large. Generally, it is above 80dB. If it is used in a lower temperature environment, it will not only present a large noise, but also a consensus phenomenon.

The frame of all the pipe bending machine is basically the structure of the box and is welded. It is similar to the appearance of the speaker, so the noise is also certain. If it is severe, the noise will be enlarged because the temperature is lower. The grease of the lubricating oil in the pipe bending machine will also increase, and the sealing ring in the equipment will also increase the resistance to shorten the movement, and the noise will be formed.

When the frame of the pipe bending machine is welded, the quality of the welded parts must be ensured, and the deformation state of the welding may be minimized, so that the noise of the bending machine can be appropriately lowered, and when the sealing ring is selected, It is best to choose a grease that is resistant to low temperatures, which is critical to the presentation of the bender noise.

The control system can make the workers operate the machine more sensitive and convenient; the control system has the function of fault diagnosis. When the machine presents a problem, it can assist the operator and the maintenance personnel to determine the cause of the problem and eliminate the fault returning to normal operation; in the process of bending, the operation The parameters are optional and adjustable, so that the system can be used to the production of different bend products. For different bend products, only some process selection and parameter adjustment are needed without changing the program.

The function of the CNC pipe bending machine is different from that of the general pipe bending machine. It is only more accurate, more efficient and faster. It is mainly used for electric power construction, public railway construction, boiler laying, bridge, ship, furniture, decoration, etc. It has many advantages such as multi-function, reasonable structure, simple operation, convenient movement and fast device.

In addition to the function of the elbow, the machine can also use the cylinder as a hydraulic jack. Compared with the numerical control elbow equipment, it has the characteristics of low price and convenient use, and it has the dominant product orientation in the domestic tube bending machine market.

How to use tube bending machine correctly

It is extremely important to use pipe bending machine in a human and intelligent way. The safety of the operator and the mold unit personnel is as important as the life of the bender. Appropriate use and maintenance of the bender will add to the life of the bender. However, incorrect use can lead to accidents and there are serious risks. The use of a bender for faults may not be intentional, but it will accelerate the wear of the bender parts and the degradation of various functions.

There is a safety guard beside the bent arm of cnc tube bender. If the operator enters the action range of the meandering arm, the elbow arm will stop suddenly when the elbow arm grips the operator, and the screen will show an alarm to prevent The personnel were severely pinched.

When the bender is in an emergency, you can press the emergency stop button to stop the power supply to prevent risk. After the risk is removed, you need to boot from scratch. Make sure the power is turned on before turning it on from the beginning.

1. The orientation of the emergency stop button

On the operator panel: Pressing this button will abort all motor and servo power.

2. Prevent overload

Indiscriminate use of the bender equipment will create an overload of the bender parts. Excessive load may not be intentional, but it is easy to happen. This is because the torque required for the twists and turns of the pipe is greater than the original torque range of the pipe bender.

Recognize the load in the operation of the bender to prevent overloading of the machine components, otherwise it will affect the service life of the bender and the safety of the operator.

Just telling! The biggest tortuosity is the most standard of the tensile coefficient 40Kg/cm2 of the tortuous general iron pipe.

Please be sure to adhere to these skill standards, otherwise it will cause serious damage to the bender.

3. Safety training

Through professional pre-job training and check-up, it is possible to prevent accidental damage that may occur during production or to minimize it. It is necessary for the safety training program to be supervised by leaders and managers. It is necessary for managers to be sensitive to safe work in all their job duties.

In order to achieve maximum maintenance, proper training is necessary. It is common to infuse employees with the safety concept of the working environment and machine operation, and attach important rules such as mold device guidance, safety devices and operation methods and personal safety to individual safety awareness.

The CNC pipe bending machine needs to refuel during the operation process, but this is not a simple operation. There are many things that require special attention, otherwise the effect will be affected. If you have any questions, you may wish to follow the steps below and you will be successful.

Before refueling the CNC pipe bending machine, it is necessary to clean the internal debris of the fuel tank and clean it. Also check whether the oil filter net is intact, and ensure that the filter function can be completed normally. After the end, the oil can be gradually poured into the fuel tank until the fuel tank cap is reached at the oil mark rule.

However, the refueling of the whole equipment has not been completed, and then carefully observe whether there are other parts that need to be refueled, such as a reducer, etc.; then, the smoothing point of the oil is added to the root to achieve a smooth and smooth effect.

Timing out the water and sediment in the hydraulic pipe bending machine tank, it is very important to remove the impurities in the oil. Together with this, the oil in the entire hydraulic system must be emptied regularly. This is to completely remove the system impurities and the oxidized hydraulic pressure. Oil and other harmful substances. After the end, the need to clean the hydraulic pressure has been added to the system from scratch.

Since good hydraulic fluids contain a variety of additives, these additives prevent oil enthalpy or block system parts, but after long-term use, no one can ensure its efficacy, thus requiring regular replacement. . In addition to draining and refueling, the timing replacement filter is also one of the actions to keep the hydraulic pipe bender system clean in order to keep the system clean.

At present, the industrial structure of the pipe bending machine mold needs to be adjusted. In terms of enterprise management, product structure, technological innovation and other aspects, enterprises should take active measures to adjust and encourage specialized production, type, precision, complexity, and long bending. The development of machine molds will make the mold production independent; support and encourage the construction of a high-level mold production and accumulation base, and gradually form a regional mold industry chain through market operation, and actively form a group of large market capabilities and More technical companies have become the industry leader.

The manufacturing level of the mold industry determines the quality of industrial products. Because of the importance of molds, it has always been valued in industrial development. If industries are to develop faster, they need to mobilize various positive factors, and manufacturing technology has become a bending machine. One of the important signs of the development of mold enterprises. At present, the development of the mold industry requires government support, revitalization of the mold industry, the introduction of key equipment and mold market technology, to encourage enterprises in the introduction of high-tech and products.

According to the development of the domestic market, the “scale effect” of mold design should be listed as the focus of industry development, and play an important role in promoting the development of the mold industry. In response to the development priorities of the industry, the government should include a small number of key mold projects, become a national special project, and implement policy inclinations. Enterprises should invest in the development, research and innovation projects of mold technology to promote the technology development and technological breakthroughs in the mold industry to rapidly improve the technical level of the industry.

With the continuous development of domestic industry, quality inspection has become an indispensable part of the bending machine mold manufacturing, and has greatly improved the quality level of the mold industry. In promoting mold standards and mass production, we should do a good job in the convergence of mold standards, promote the coverage of mold standards, and continuously improve the standardization of the industry. At present, the mold industry needs to develop technological innovation to adapt to the current complex situation.

According to the knowledge in the "elastoplastic mechanics" textbook.

This is a moment balance equation with the external force moment on the left and the internal force moment on the right, which is equal to the integral of the entire section of the moment generated by the stress on the neutral axis. When bent, the axis of the tube is the central axis.

If the outer diameter D, the inner diameter d, and the yield limit σs of the round pipe are deformed by the bent pipe on the master having the radius of curvature R, the inner ring radius of the pipe is R. The distance between the point where the tube is bent and deformed is L, and the material is not hardened. When the tube is deformed, the entire clean surface enters a plastic state.

Therefore: P*L=2*Integral{2*x*dy*σs*y,0,D/2}-2*Integral{2*x*dy*σs*y,0,d/2}

            ={D^3-d^3}*σs/6

         P={D^3-d^3}*σs/[6*L]

      This is the amount of bending force when the material is not hardened.

According to the data, 70% of the steel production needs to be processed by deformation, and the metal forming work should process 2/3 of the steel. It has been estimated that each remanufacturing of plates, tubes and profiles requires one bender, a coiler and a profile bending machine. In recent years, the expansion of the pipe bending machine has formed a considerable scale in China, and its production level is also constantly advancing. It has had a profound impact on the level of advancement of the system and the promotion of China's industrialization process.

The increasingly expanding aerospace, military weapons, automobiles, rolling stock, instrumentation, shipbuilding, chemical, pressure vessels, metallurgy, engineering machinery, metal components, etc., the demand for pipe bending machines is increasing, the accuracy of pipe bending machine requirements Higher and higher. Following the rapid development of China's manufacturing operations, the shipbuilding industry has put forward higher requirements for the utility of the ship bending machine with the folding and composite function of the general bending machine, reliability, safety and automation. The power industry is rapidly expanding. The wind power, coal-fired power, hydropower, nuclear power and national clean power guidelines are encouraged. The pipelines, column towers, etc. require a large-scale set of pipe bending machines; offshore oil, natural gas, petrochemical, coal chemical, etc. The trend of large-scale and high-parameterization of container products is becoming more and more obvious. Thousand-ton hydrogenation reactors, two-ton-ton coal liquefaction reactors, and 10,000 cubic meters of natural gas spherical tanks are used in many places in China to form thick plates. Large-scale pipe bending machines with high-strength plates become key equipment.

During the operation of the bender, all components of the bender can be maintained under harsh environmental conditions (such as rain), improper operation and misuse, and overload. All systems of the bender are suitable for operation in ±40 ° C and 0 ~ 100% humidity environment. The pipe bender is suitable for local use at an altitude of 0 to 3000 m. The appropriate working place should be selected before the pipe bending machine works. The site can satisfy the accumulation of straight pipes and elbows, and it should also ensure that the pressure of the equipment can be accepted on the ground. Bending function, to check whether the appearance of the anti-corrosion mother tube has oil, pits, tortuous, anti-corrosion layer folds, anti-corrosion number and tube number identification is not clear or writing fault, crusting, mechanical damage and other appearance defects, and Do a good job of checking the records.

Elbow bend maintenance method

1. Elbows bent for a long time should be checked as scheduled. Often, the exposed surface should be cleaned, dusted, and neatly stored in the airy and boring area. It is strictly prohibited to be stacked or stored in the open air. Often adhere to the boring and ventilating of the elbow, insist that the device is clean and tidy, and deposit according to the precise storage method.

2. When the equipment is used, the elbow elbow can be directly connected to the pipeline according to the connection method, and the equipment is carried out according to the applied orientation. Under normal circumstances, the equipment can be in the direction of the pipeline, but it needs to be easy to check. Note that the flow direction of the cut-off elbow should be upward from the longitudinal valve, and the elbow can only be horizontal. When the elbow is in the equipment, pay attention to the sealing, avoid the leakage phenomenon and affect the normal operation of the pipeline.

In addition, the primary influence of the bending speed of the bender on the forming quality is:

The speed is too fast, the flatness of the tortuous part of the catheter is simply formed, the roundness is not up to the requirement, the cracking and breaking of the catheter are formed; the speed is too slow, the wrinkling of the catheter and the compression block slip are simply formed, and the tube of the large diameter is easy A depression of the tortuous portion of the catheter is formed. For a large number of tests on these two CNC pipe bending machines, it is advisable to determine the tortuous speed of the pipe to be 20% - 40% of the maximum bending speed of the machine.

Maintenance and maintenance of the automatic cnc tube bender:

1. Operate in strict accordance with the operating procedures.

2. Before each start-up, press the smooth chart to ensure punctuality, fixed point, and quantitatively add smooth oil. The oil should be clean and free of sediment.

3, the bender is necessary to always adhere to clean, unpainted part of the anti-rust grease.

4, the smooth grease in the motor bearing should be replaced regularly, and often check whether the electrical part of the operation is normal and safe.

5. Check the triangle belt, handle, knob and button of the bending machine regularly for damage. If the wear is serious, replace it in time and report the spare parts to make up.

6. Before going to work every day, smooth the machine tool and wipe the machine.

7. The blade should be tightened regularly and oiled.

8, can not cut the plate beyond the rated pressure.

9. It is forbidden for non-designated personnel to operate the equipment. It is usually necessary to stop people from leaving the aircraft.

CNC tube bending machine maintenance

1. Do not put your hand between the upper and lower blades to avoid accidents.

2. It is necessary for the operator to understand the structure and function of the machine. This CNC bending machine is operated by many people, so it is necessary to have a special person to be the conductor.

3. All the sundries and things should not be placed on the workbench, so as to avoid damage to the edge of the blade.

4. The sharpness of the knife edge should be checked regularly. If the knife edge is found to be blunt, it should be ground or interchanged in time. The grinding of the blade requires only the thickness of the blade to be ground.

5, should regularly check the various parts of the machine, and adhere to the cleaning of the machine and surrounding places, the outstanding line insulation of the power supply is outstanding.

6. The net type oil filter placed on the oil pump suction port should always check the cleaning so that the oil filter adheres to the oil flow. If the oil filter is blocked, the oil flow is reduced, which will cause the oil pump to suck and affect the oil pump. The service life makes the machine not work properly.

7. The accumulator is filled with nitrogen and cannot be filled with oxygen, compressed air or other flammable gases. When filling with nitrogen, apply a special dedicated air tube that is randomly equipped, and the pressure should not exceed 8 MPa.

8. This CNC bending machine is designed to be smooth and smooth, so please smooth the smooth points for daily operation.

Pipe bending machine operation principle

The upper blade is fixed on the knife holder, the lower blade is fixed on the lower bed surface, and the equipment on the bed surface has a ball for the feeding movement of the sheet material, and the rear material blocking plate is used for positioning the sheet material, and the orientation is adjusted by the positioning pin. . The hydraulic cylinder is used to compress the sheet to prevent the sheet from turning over during shearing. Shed panels are safety equipment to avoid work injuries.

(1) Adjust the front bezel

Hold the tailgate against the lower edge, and then press the template against the rear bezel to hold the front bezel against the template and fix it. Loosen the tailgate, remove the template, load the sheet, and cut.

(2) Adjusting the tailgate

Align the sample plate with the lower knife edge, and then press the back plate against the template and fix it, remove the template, and then load the plate for cutting.

(3) Adjust the angle baffle

First place the template on the table to align the lower edge, adjust the angle baffle and fix it, and then adjust the tailgate according to the template. Use the angle baffle and the tailgate together for positioning during the cutting process.

The layout of pipe bending machine should ensure the convenience of feeding, setting, unloading and collecting waste. The processing of small parts is to prevent the operator's fingers, wrists or other parts of the body from reaching the mold area. Regarding the processing of large parts when the operator has to manually work in the mold. It is necessary to reduce the planning of the mold, and to shorten the time that a part of the body stays in the mold, and to clarify the necessary protection methods and equipment for the mold danger zone of cnc automatic tube bender.

The hydraulic pipe bending machine is a two-cylinder parallel push hydraulic pusher. The pump station adopts the integrated connection mode and the repair is simple. The pump box is divided into two parts. The primary fuel tank is used for the cleaning plan of the filter. When the main filter is cleaned, the fuel tank is separated from the main connection of the main ft door, the fuel tank of the auxiliary fuel tank is released, and the oil pump is turned into the fat blue. Remove the filter and clean the filter with gasoline or diesel. The original device can be returned.

What is the efficiency of the pipe bender, the key is the laser processing skills; and the fine laser processing skills of the bender can process a variety of workpieces, because it does not need to be in direct contact with the cut workpiece during the cutting time. Therefore, the high-energy laser beam generated by the bender can move freely, so that the appearance of the cut workpiece is evenly heated, so the precision of cutting is very high; and the fine laser processing skill can cut all the workpiece data. Whether it is high melting point, high brittleness and high hardness, and the cutting effect is very good; because of the fine laser processing skills of the bending machine, it is very popular among users.
