Firstly, the soft starter is inspected by the CNC tube bender in detail, mainly to see if there is any wiring error in the main circuit and the control loop; secondly, the connection mode of the motor on the soft starter panel is “external” position; then the setting standard The parameter, the starting ramp time is set to 10 seconds, and the starting current is limited to 3 times. After the main circuit is energized, the control system sends a soft start signal to start the main motor.

Through repeated experiments, the optimal starting parameters of the vertical bender soft starter are obtained. The starting ramp time is 6 seconds and the starting current is limited to 2.8 times. Because it is a repeated test, it will cause a large increase in the number of starts, so you must pay attention to the following two problems:

(1) The cooling fan of the soft starter electric control cabinet should be running all the time to facilitate the smooth cooling of the power thyristor in the soft starter and reduce the junction temperature.

(2) There should be a 10-15 minute interval between each start to allow the power thyristor in the soft starter to cool down, thereby preventing the soft starter from alarming due to overheating.

Three-dimensional CNC pipe bending machine mold laser cutting is mainly applied to flat cutting and three-dimensional five-axis linkage three-dimensional cutting, high-strength steel is used for the body frame, to reduce the weight and improve the car while ensuring the strength and rigidity of the body. The crash-worthiness and anti-concave properties of the body significantly increase the safety of the car. For high-strength steel structural components with complex contours, laser cutting is a very effective tool for both technical and economic reasons.
2. Automotive white body top cover laser welding equipment This equipment is used for automobile body-in-white top cover welding. The equipment consists of two robots, a fiber laser, a wire feeder, a welding head, a laser protection room and a floor fixture. Work with a robot with a laser welding head for welding. The top cover clamp is carried by the robot, and the four V-shaped positioning blocks are matched with the positioning support frames on both sides to form a positioning. The four clamping cylinders on the positioning support clamp the top cover clamp. There is a quick change device between the top cover fixture and the robot, which can be switched between multiple models. Different from the traditional spot welding process, laser welding can achieve the molecular combination between two steel plates. Generally speaking, the hardness of the steel plate after welding is equivalent to a whole steel plate, thereby increasing the strength of the body by 30%. Also greatly improved, on the other hand, the overlap width and some reinforcing members can be reduced, and the volume of the body structure itself can be compressed, thereby reducing the weight of the vehicle body.
3. Off-line automotive tailor welded blank forming equipment Most steel plates used in automobiles are galvanized steel sheets, and the resistance welding process will destroy the galvanized protective layer. Therefore, laser welding is an ideal process for achieving welding and welding, which can ensure the formation of qualified welds and meet the requirements of corrosion resistance, high strength and fatigue resistance. The laser welding technology has many advantages, the weld seam is very narrow, and the heat affected zone is small. Through the long-range sacrificial effect of zinc, the weld seam can be not corroded for a long time, and the faster the welding speed, the higher the weld hardness.
4. Car stealth airbag instrument panel laser weakening equipment This equipment has linkage numerical control function, which can cut the workpiece of any shape, mainly used for the weak processing of the car stealth airbag instrument panel. The structure of the device is reasonable in design, with sufficient static, dynamic and thermal stiffness. The system has good dynamic quality and can show high precision in actual processing. The device is stable and reliable, easy to use, operate and maintain, and has a beautiful appearance.

9. Laser welding of the trunk of the car The trunk consists of a trunk lid and a rear panel. Because the forming has a 90° angle, the laser brazing is used for fillet welding. The traditional trunk welding is carried out by MIG brazing. Since the trunk material is usually galvanized, the low heat input of MIG brazing is used to solve the problems caused by the large burning of the galvanized layer, but the high-speed welding of MIG brazing and The instability of the arc at low current limits its efficiency and quality. Laser filler wire is mainly used for welding with complex welding or sharp change of weld tangential direction. The welding forming surface is smooth and it is difficult to form a smooth weld. In addition, MIG Brazing is highly polluted. If laser brazing is used, the welding speed is high, the weld bead is formed well, the quality is stable, and the galvanized layer is less burned.

Safety maintenance method for pipe bending machine safety valve

Safety maintenance method for pipe bending machine safety valve

The pipe bending machine safety valve is a component that is automatically unloaded when the high pressure is exceeded in the autoclave. Therefore, the autoclave as a high pressure container should be equipped with two at the same time, so that when an accidental failure occurs, Generally should be slightly below the allowable pressure value. In order to ensure the good performance of the bender safety valve, regular maintenance and routine maintenance work must be carried out.

The  pipe bending machine safety valve is a component that is automatically unloaded when the high pressure is exceeded in the autoclave. Therefore, the autoclave as a high pressure container should be equipped with two at the same time, so that when an accidental failure occurs, Generally should be slightly below the allowable pressure value. In order to ensure the good performance of the bender safety valve, regular maintenance and routine maintenance work must be carried out.
1. After the switch door product enters the kettle, the kettle door should be carefully closed, so that the kettle door and the kettle ring are in place, and the safety raft is pulled down. Before the gas supply is finally checked, the kettle door closure condition is completed and the maintenance is completed before the kettle door is opened. Care must be taken to check for pressure in the kettle. And first open the safety 筏, so that the steam in the kettle can be opened before the kettle door can be opened, and the operator is prevented from facing the kettle door to prevent being burnt by the high temperature steam.
2. Maintaining the hydrophobicity of the autoclave, which is subjected to the internal pressure caused by the steam, and the load of the autoclave and the weight of the steaming car and the product on the track fulcrum and the kettle body. The stress formed by the difference in stability between the top of the kettle and the bottom of the kettle due to condensed water. Under the cyclical stress for a long time, the autoclave easily causes the material to fatigue and lose part of the strength. At the same time, the corrosion of water and gas is also easy to reduce the strength of the material. Therefore, we should discharge the condensed water in time during the use, especially in the initial stage of the temperature rise. A large amount of condensed water is generated in the kettle. If it is not removed in time, it will accumulate at the bottom of the kettle to make the kettle body work to form a low temperature zone. The temperature difference between the upper and lower sides is increased (generally about 10 degrees Celsius. It is also possible to reach 60-70 degrees Celsius), and the excessive stress difference and thermal deformation difference in the upper and lower sides of the kettle are formed.

Automated enterprises can purchase similar automation equipment to further reduce costs and take the opportunity to tide over the difficulties under the wave of China's automatic tube bending machine transformation and upgrading. At present, China's fully automatic pipe bending machine enterprises are facing a complicated international situation, and domestic competition is extremely fierce, making many enterprises unable to move. So what is the difference between a two-dimensional pipe bender and a three-dimensional pipe bender? Taiwan and mechanical experts tell you

Due to the different users in various industries, the process objects and processes are also different. The construction of CNC numerical control pipe bending machine mainly adopts three methods:

A. Directly adopt embedded CNC system. The advantage is that the degree of freedom of programming is high, and it can be based on different pipe bending requests, without excessive mechanical intervention, and the programming can be completed, but the programming quality requirements for the personnel are relatively high. Ordinary models do not support the input of elbow XYZ geometry coordinate data.

B. Control mode separated by programmable controller PLC, position/speed control unit, touch screen and AC servo drive unit. PLC ladder diagram, STL programming control the organic separation of the position/speed unit and the touch screen, directly input the bending process data, and support the conversion of the elbow XYZ geometric coordinate data to the elbow YBC processing data. PLC hardware has high reliability, strong anti-interference, easy to maintain and re-develop software.

C. Industrial grade computer, servo motion control board, AC servo unit, system software is completed by C language or VB visual program, which can make full use of computer resources diversity and functionality, can be used for complex motion processes, mechanical trajectories, etc. Applications such as complex mechanical structures. In addition to the utility of the second method, it also increases the utility of pipe processing machinery intervention. The reliability of the hardware is slightly lower than that of the PLC system. It adopts the control mode of PLC, position/speed control unit, touch screen and AC servo drive unit. The designed system has two modes: manual and automatic operation. In the automatic mode, it can be divided into step-following bending and origin-string bending, which is convenient for processing a variety of complex pipe fittings.

Regarding the pipe fittings with different bending radii, the upper and lower die switching is used to complete the processing of the pipe bending operation. For the bending of the pipe fittings for special machining requests, actions such as linkage, synthesis and corresponding auxiliary pushing are designed to prevent mechanical intervention and complete the automation of the pipe bending process. Automatically cooperate with the automatic loading and unloading machine to realize unmanned automatic production, achieve automatic production in the true sense, low dependence of automatic equipment on people, realize intelligent production, information exchange compatibility, workshop, office, leadership, The quality of the product has been further leapfrogged by the entire production process.

Suzhou Wonsten specializes in the production, CNC tube bending machine, automatic tube bending machine and other equipment, the company abides by: "Quality first, customer first, integrity-based" business philosophy, sincerely welcome new and old customers to visit We will provide you with a full range of services.

How to solve the problem of slow working speed and degreasing of hydraulic pipe bending machine

How to solve the problem of slow working speed and degreasing of hydraulic pipe bending machine

Hydraulic pipe bending machine generally has a speed of bending pipe. When the pipe is small, the fastest gear is used. When the pipe is small, the slow gear is used. Like the above speed control method, on the control panel, press the prompt to modify it. . If you want to solve the problem, I suggest you buy a fully automatic CNC hydraulic pipe bending machine, which can process about 1000 tubes a day.

1. How to adjust the working speed of the hydraulic pipe bending machine:

2. How to adjust the speed of the hydraulic bending machine in the work?

The bending machine is a 2.5-meter double cylinder. The cutting point of the cutter is different. The cylinder is newly repaired. It does not fall into the cylinder. What should I do? Note: The domestic hydraulic pipe bending machine works with high strength and the service life will be very short. It is recommended that you look at the imported ones.

Two stroke switches next to the machine, one is the height limit, the other is the pressure relief, and the pressure relief is lowered a little, it is slower.

3, hydraulic hydraulic pipe bending machine in the work, the oil speed is slow, the oil speed is fast, how is it?

Generally, when the weather is cold, the oil intake speed will be slower, because the viscosity of the oil is high, so it is slow. It takes only one hour to use it. It is better not to adjust the speed of the work and the speed of the work. It is easy to mess. If you want to ask why the oil in the tank is slow when it comes in, then you are not clear about the hydraulic pipe bender. When the work is pressed down, the oil in the cylinder is sucked into the cylinder through the large hydraulic control valve, and is pressurized by the valve body when the work is advanced. When returning, the oil is returned to the valve body. The oil is flushed like a flush. The large hydraulic control valve is not with the valve group but is hung there on the front side of the fuel tank, so you can only watch it. Go back to the oil surfing. You can't see the oil absorption, the oil absorption has a large diameter. On the front side, you should never touch it, and you can't hold it.

How to determine the model of pipe bending machine

How to determine the model of pipe bending machine

The bending method of our factory is mainly cold bending. The models are hydraulic bending machine and three-roll bending machine. The "pipe bending machine" is a curved "tube". In fact, it can also bend "I-beam". "channel steel", "angle iron" "wire", etc.; can also be rolled coil, "u" type tube, half tube, coiled tube and so on.

In fact, it can also bend "I-beam". "channel steel", "angle iron" "wire", etc.; can also be rolled coil, "u" type tube, half tube, coiled tube and so on.
In reality, many customers call me and start asking how much the bender is? This makes me unable to answer positively: just say a price, it is irresponsible to the customer; not to mention it, I feel that I am not enough! Here, I will tell you in detail how to properly use the bender?
The company purchases pipe bending machines in order to reduce labor intensity, improve production efficiency, improve product quality, and thus enhance the competitiveness of enterprises. The savvy boss will choose the model that is most suitable for their own production (the best for their own is the best). of)! What kind of pipe bending machine is most suitable for its own production?
First of all, according to the actual production situation, determine the pipe diameter range of the elbow. Many pipe fittings use pipe bending machines for various pipe fittings. Each pipe bending machine is not a panacea. It has its own parameters that limit the bending capacity. For example: DW38NC hydraulic pipe bending machine The maximum diameter of the bend is 38.1mmX3.0mm (based on ordinary carbon steel pipe material, the wall thickness varies according to the material); the maximum diameter of the DW120NC hydraulic pipe bending machine is 120.3mmX8.0mm! The price of each type of pipe bending machine is different. Besides, if you choose an oversized model, it will be a waste of resources. If the selected model is too small, there will be a laborious feeling of "small horse-drawn cart". In turn, affect the service life of the machine!
Secondly, it is necessary to determine the elbow parameters of the largest pipe fittings in the range of the elbow, including: 1. Pipe fitting material (steel pipe, stainless steel pipe, aluminum pipe, etc.); 2. Pipe section (round pipe, square pipe, angle iron, etc.) 3, tube outer diameter; 4, tube wall thickness; 5, bending radius (refer to the tube diameter); according to the above-mentioned bending parameters, so as to choose the most suitable bender, is the best decision

How to maintenance pipe bending machine?

How to maintenance pipe bending machine?

1. Long-term storage of elbow bends of benders should be checked on schedule. The exposed surface should be kept clean, dirt removed, and stored neatly in a place where air is dry and dry. It is strictly prohibited to be stacked or stored in the open air. The elbow is often kept dry and ventilated, the holder is clean and tidy, and stored in an accurate storage method. 2. When installing, the elbow elbow can be directly installed on the pipeline according to the connection mode, and installed according to the position used. Under normal circumstances, it can be installed at any position of the pipeline, but it is easy to check the operation. Note that the flow direction of the cut elbow medium should be upward from the longitudinal valve flap. The elbow bend of the small bender can only be installed horizontally. The elbow should pay attention to the sealing during installation to prevent leakage and affect the normal operation of the pipeline. In addition, the main influence of the bending speed of the single-head bending machine on the forming quality is: The speed is too fast, it is easy to cause the flat part of the pipe to be flat, the roundness is not up to the requirement, causing the pipe to be pulled and broken; the speed is too slow, it is easy to cause the wrinkling of the pipe and the pressing block to slip, and the pipe with large diameter is easy. A depression of the curved portion of the catheter is formed. For a large number of tests on these two CNC small pipe bending machines, it is advisable to determine the bending speed of the pipe to be 20% - 40% of the maximum bending speed of the machine.
