What Are The Operating Technical Characteristics Of The Pipe Bender? 返回首页

The CNC Pipe Bender is mainly used for pipe laying in boilers, bridges, ships, electric power construction, highway and railway construction, etc. The CNC pipe bender is simple to operate, convenient to move, and fast to install. It occupies the leading product position in the pipe bender market and is widely used. , So what are the technical characteristics of the CNC pipe bending machine? The cold Hot Elbow Machine Manufacturer will help us.

1. Proper bending radius value

The bending radius of the catheter determines the resistance of the catheter during bending. Generally speaking, a large pipe diameter and a small bending radius are prone to internal wrinkles and slippage during bending. The bending quality is difficult to guarantee. Therefore, the R value of the pipe bending die is generally 23 times the pipe diameter.

2. Regulatory regulation

The Cold Elbow Machine Exporter recommends avoiding excessive arcs, arbitrary curves, compound bends and greater than 180 when designing and arranging pipes. The arc. Excessive arc not only makes the tooling bulky, but also is limited by the size of the pipe bending machine; the design of arbitrary curves and compound bending is very unreasonable, which greatly hinders mechanized and automated production and makes it difficult for operators to get rid of heavy manual labor; Greater than 180. The arc makes the bending machine unable to unload the mold.

3. Suitable mandrel and its position

The core rod mainly functions to support the inner wall of the bending radius of the catheter to prevent its deformation during the bending process. At present, the quality of domestic pipes is difficult to guarantee if mandrels are not used for bending forming on machine tools. There are many types of mandrels, such as cylindrical mandrels, universal single-, double-, triple-, and four-ball mandrels, directional single and multi-ball mandrels, etc. In addition, the position of the mandrel also has a certain impact on the bending of the pipe: theoretically, its tangent should be flush with the tangent of the pipe bending die, but after a lot of tests, it is better to be 1~2mm ahead of time. At this time, the quality of the pipe is better. Ideal. Of course, too much advance will cause the so-called "goose head" phenomenon on the outer wall of the curved part.

4. Moderate bending speed

The main influence of the bending forming speed on the forming quality is: too fast, it is easy to cause the flattening of the bent part of the catheter, and the roundness is not up to the required, causing the catheter to tear or break; too slow, easy to cause the catheter to wrinkle and The compression block slips, and the pipe with a large pipe diameter is easy to form a sinking of the curved part of the pipe. For a large number of tests on these two CNC pipe benders, it is advisable to determine the bending speed of the pipe at 20%-40% of the maximum bending speed of the machine.

5. Standardization of bending radius

The bending radius should try to achieve "one tube, one mold" and "multiple tubes, one mold". Regarding a pipe, no matter how many bends and the bending angle, there can only be one bending radius, because the pipe bender does not replace the module during the bending process, this is "one pipe, one mold". "Multi-tubes and one mold" means that tubes of the same diameter should be bent with the same bending radius as much as possible, that is, using the same set of modules to bend different shapes of tubes, so as to reduce the number of modules.
