What are the operational technical characteristics of CNC pipe bending machines?
CNC pipe bending machines are mainly used for power construction, public railway construction, pipeline laying and repair of boilers, bridges, ships, and other aspects. CNC pipe bending machines are easy to operate, easy to move, and fast to install, occupying the leading product position in the domestic pipe bending machine market and widely used. So what are the technical characteristics of CNC pipe bending machines?
1、 Pipe type normalization
When designing and arranging pipes, it is necessary to avoid excessively large arcs, arbitrary curves, composite bends, and larger than 180. Arc of. The excessively large arc not only makes the fixture bulky, but also limited by the size of the pipe bending machine tool; The design of arbitrary curves and composite bends is very unreasonable, greatly hindering mechanized and automated production, making it difficult for operators to get rid of heavy physical labor; Greater than 180. The arc makes it impossible for the pipe bending machine to unload the mold.
2、 Standardization of bending radius
The bending radius should be achieved as much as possible; One tube the first mock examination and multiple tubes the first mock examination. For a pipe, no matter how many bends there are, and what the bending angle is, the bending radius can only be one, because the pipe bender does not change the module during the bending process, which is a the first mock examination for one pipe. Multiple pipes with one the first mock examination means that pipes with the same diameter and specification should use the same bending radius as far as possible, that is, use the same set of modules to bend pipes with different shapes, which is conducive to reducing the number of modules.
3、 Appropriate bending radius value
The size of the bending radius of the catheter determines the resistance it experiences during bending and forming. Generally speaking, with a large pipe diameter and a small bending radius, internal wrinkling and slipping are prone to occur during bending, making it difficult to ensure bending quality. Therefore, it is generally better to choose a bending die with an R value of 23 times the pipe diameter.
