Automation equipment has the advantages of high efficiency, reduced labor costs, and increased labor productivity. 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.

1. How to adjust the working speed of the 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.

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.

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 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

1. Long-term storage of bends of pipe bending machine 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, pipe bending machine 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  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.

The hydraulic pipe bending machine ought to be operated at a similar time for the mechanism capable of automatic or semi-automatic work (such as pipe clamping, guiding compression, spindle advance and retreat, gyrator rotation and angle pre-selection mechanism, etc.), whereby the continual cycle period isn't but 2h. for every sub-program action (ie, pressing a button, one action) within the higher than cycle, the operation time isn't but one.5h, and also the operation method should be administrated in sequence in step with the operating procedure such that by the look. within the continuous cycle operation take a look at, the button pause time between every cycle is mostly inside thirty s; within the operation take a look at of the sub-program action, the button pause time between every sub-program action is mostly inside five s. For the preceding hydraulic pipe bending machine operating mechanism will solely be operated by hand, solely the continual 4h idle take a look at is administrated. For the most drive with adjustable speed, the running take a look at ought to be administrated in step with the low, medium and high speed binning. The period of every gear speed isn't but zero.5 h.

The hydraulic pipe bending machine may be a hydraulic automatic pipe finish process machine that controls the tip surface of the pipe in an exceedingly traditional state, associated is managementled by an integrated control bit screen, and also the pipe will be expanded , contracted, bulged, and replaced by a mildew. The tube ends square measure fashioned by the ribs and might be freely determined in step with the user's wants. Manual, jog or automatic machining machine tools square measure used. The fuel tank, bed, slider, main cylinder, mildew core rod (optional), limit cylinder, compact the most elements square measure composed of oil cylinder, clamping die and axial positioning cylinder, and axial positioning bracket.

Tube type regularization

   Avoid excessive arcs, arbitrary curves, compound bends, and arcs greater than 180° when designing and piping. Excessive arc not only makes the tooling heavy, but also limited by the size of the machine of the pipe bending machine; the arbitrary curve and compound bending design is unreasonable, which greatly hinders the mechanization and automatic production, making it difficult for the operator to get rid of the heavy physical labor; An arc larger than 180° prevents the bender from being unloaded.

Bending radius standardization

   The bending radius should be as far as possible to achieve "one tube and one mold" and "multiple tubes and one mold". For a pipe, no matter how many bends, the bending angle can only have one bend radius, because the bender does not replace the module during the bending process, which is "one tube and one mold". The "multi-tube and one-module" means that the same diameter pipe should use the same bending radius as much as possible, that is, the same set of modules can be used to bend different shapes of the pipe shape, which is beneficial to reduce the number of modules.

Bending radius

   The size of the bend radius of the catheter determines the amount of resistance the catheter is subjected to during bending. Generally speaking, the large diameter of the pipe diameter is small, and the wrinkles and slippage are likely to occur during bending. The bending quality is difficult to ensure, so the R value of the pipe bending die is generally 2-3 times the diameter of the pipe.

Bending speed

   The main influence of the bending forming speed on the forming quality is that the speed is too fast, the flatness of the curved part of the duct is easy to be formed, the roundness is not required, and the duct is pulled and broken; the speed is too slow, and the wrinkling of the duct is easy to occur. The compacting block slips, and the large diameter pipe tends to form a depression of the curved portion of the conduit. For a large number of tests on these two CNC 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.

Mandrel and its position

   The mandrel mainly plays the role of supporting the inner wall of the bending radius of the conduit during the bending process to prevent deformation thereof. The domestic pipe is bent on the machine tool. If the mandrel is not used, the quality is difficult to guarantee. There are many types of mandrel rods, such as column core rods, universal single, double, triple, and four-ball head core rods, oriented single and multi-ball head core rods. In addition, the position of the mandrel also has a certain influence on the bending of the pipe: in theory, its tangent should be flush with the tangent of the pipe mould, but after a large number of tests, it is better to advance 1~2mm, at this time the quality of the pipe More ideal. Of course, the amount of advance is too large, which causes a phenomenon of so-called "goose head" on the outer wall of the curved portion.
