One-stop Bending Solutions For Wires, Tubes And Pipes
In today’s industrial manufacturing and various engineering construction fields, CNC pipe bending machines play a vital role. What exactly is a CNC pipe bending machine? What practical scenarios is it suitable for?
Ⅰ. Application of CNC pipe bending machine
As a professional electric tool, the pipe bending machine can accurately bend metal pipes into specific angles or smooth arcs. It combines versatility, scientific structure, and convenient operation, with significant advantages. It is widely used in many fields such as power construction, road and railway construction, boiler manufacturing, bridge construction, ship repair, furniture production, and interior decoration, and has made contributions to various pipeline laying and fine repair projects.
The CNC pipe bending machine has achieved an upgrade and iteration based on the traditional pipe bending machine. With its excellent characteristics of high precision and high speed, it can efficiently process common metal materials such as iron, aluminum, stainless steel, and even iron wire, copper wire and other materials, with an accuracy that makes people shine.
Ⅱ. What are the operating technical characteristics of the CNC pipe bending machine?
CNC pipe bending machines are mainly used for laying and repairing pipelines in power construction, road and railway construction, boilers, bridges, ships, etc. CNC pipe bending machines are simple to operate, easy to move, quick to install, and widely used. So what are the technical characteristics of CNC pipe bending machines?
1. Regularization of pipe type
When designing and arranging pipes, avoid excessive arcs, arbitrary curves, compound bends, and arcs greater than 180. An excessively large arc not only makes the tooling bulky, but is also limited by the size of the pipe bending machine; the design of arbitrary curves and compound bends is very unreasonable, which greatly hinders mechanized and automated production, making it difficult for operators to get rid of heavy physical labor; an arc greater than 180. makes it impossible for the pipe bending machine to unload the mold.
2. Standardization of bending radius
The bending radius should try to achieve “one tube, one mold” and “multiple tubes, one mold”. For a pipe, no matter how many bends there are and what the bending angle is, there can only be one bending radius, because the pipe bending machine does not change the module during the bending process, which is “one tube, one mold”. And “multiple tubes, one mold” means that pipes of the same diameter specification should try to use the same bending radius, that is, use the same set of modules to bend pipes of different shapes, which is conducive to reducing the number of modules.
3. Appropriate bending radius
The size of the catheter bending radius determines the size of the resistance encountered by the catheter during bending. Generally speaking, when the pipe diameter is large and the bending radius is small, it is easy to wrinkle and slip when bending, and the bending quality is difficult to guarantee. Therefore, it is generally better to select the R value of the pipe bending die to be 23 times the pipe diameter.
4. Appropriate bending forming speed
The main influence of the bending forming speed on the forming quality is: if the speed is too fast, it is easy to cause the flatness of the bending part of the conduit, the roundness does not meet the requirements, and the conduit is pulled and broken; if the speed is too slow, it is easy to cause the conduit to wrinkle and the pressing block to slip, and the large-diameter pipe is easy to form the conduit bending part to sink. According to a large number of tests on these two CNC pipe bending machines, the bending speed of the conduit is determined to be 20%-40% of the maximum bending speed of the machine.
5. Appropriate mandrel and its position
The mandrel mainly plays the role of supporting the inner wall of the bending radius of the conduit to prevent its deformation during the bending process. At present, if the mandrel is not used when bending and forming domestic pipes on machine tools, its quality is difficult to guarantee. There are many types of mandrels, such as column mandrels, universal single, double, triple, quadruple ball mandrels, directional single, multi-ball mandrels, etc. In addition, the position of the mandrel also has a certain influence on the bending of the conduit: theoretically, its tangent should be flush with the tangent of the bending die, but a large number of tests have shown that it is better to advance 1 to 2 mm, and the bending quality is ideal at this time. Of course, too much advance will cause the so-called “goose head” phenomenon on the outer wall of the bending part.
