What are the operating technical characteristics of the pipe bending machine

2020-06-07

1. Regularization of tube type

When planning and discharging pipes, it is necessary to prevent excessively large arcs, arbitrary curves, compound bends and greater than 180. Arc. Excessively large arcs not only make the tooling clumsy, but also limited by the machine tool size; the arbitrary curve and compound bending planning and modeling are very unreasonable, which greatly hinders the mechanization and active production, making it difficult for the operator to disconnect the bulky manual work; . The circular arc makes the pipe bender unable to remove the mold.

2. Standardization of zigzag radius

Zigzag radius should try to achieve "one tube and one die" and "multiple tubes and one die". Regarding a pipe, no matter how many bends there are, the meander radius can only be one.

Since the modules are not replaced during the twists and turns, this is "one tube, one mold". "Multiple tubes and one mold" means that tubes of the same diameter and standard should use the same tortuous radius as much as possible, that is, use the same set of modules to bend different shapes of tubes, so that it is conducive to reducing the number of modules.

3. Appropriate tortuous radius value

The size of the tortuous radius of the catheter determines the size of the resistance of the catheter when it is tortuously formed. Generally speaking, the pipe diameter is large and the zigzag radius is small.

The internal wrinkles and slippage are easy to occur during the zigzag, and the quality of the zigzag is difficult to guarantee. Therefore, the R value of the bending die is generally 23 times the diameter of the pipe.

4. Moderate zigzag forming speed

The main influence of the zigzag forming speed on the forming quality is: the speed is too fast, it is easy to form the flat part of the zigzag part of the catheter, the roundness does not meet the requirements, and the catheter is cracked and broken; the speed is too slow, it is easy to form the wrinkle and The compression block slips, and the large-diameter tube easily forms the depression of the tortuous part of the catheter. For a large number of experiments on these two CNC pipe bending machines, it is appropriate to determine the bending speed of the catheter as 20%--40% of the bending speed of the machine. Perhaps a wheel die plus a channel can be assembled into a manual tube bender, like a pure manual tool for bending steel bars on the construction site, manpower accounts for a large proportion, as a scientist said, give him a fulcrum and be able to pry Moving the earth, the principle is exactly the same.

With the development of science and technology and the improvement of living standards, people are increasingly seeking initiative, saving manpower, seeking production power, and making more elaborate carvings, which have been slowly developed. It is also called CNC hydraulic pipe bending machine, which is numerically controlled and controlled by a computer version, which is hydraulic. The hydraulic cylinder applies pressure and the oil pump drives the transmission device to work and achieve initiative.

Now active bending has replaced manual bending. As long as a straight metal fitting or metal profile is placed in the bending mold, set the viewpoint, you can bend out the desired viewpoint, such as 90° on a table and chair Bending angle, you can bend it by stepping on the foot switch.

It can realize the integrated work of feeding, clamping and bending, which greatly saves time and provides working power. Together, the accuracy of the product has also been improved by a big step, and the product is more and more beautiful when it comes out.
