troubleshooting tips for automatic cnc pipe end forming mach As a kind of practical mechanical operation tool, in our country is widely used in the electric power construction, and railway construction, boilers, Bridges, ships, furniture, household appliances and decoration industries, Its craft is also evolving with the progress of modern technology. Generally can be divided into hydraulic troubleshooting tips for automatic cnc pipe end forming mach, etc., troubleshooting tips for automatic cnc pipe end forming mach: Troubleshooting tips for automatic CNC pipe end forming Mach: Troubleshooting tips for automatic CNC pipe end forming Mach: Troubleshooting tips for automatic CNC pipe end forming Mach: Troubleshooting tips for automatic CNC pipe end forming Mach: Troubleshooting tips for automatic CNC pipe end forming Mach

troubleshooting tips for automatic cnc pipe end forming mach Bending radius should try to achieve "one tube one mode" and "multiple tubes one mode". for a pipe, no matter how many bends and bending Angle, its bending radius can only have one, because troubleshooting tips for automatic cnc pipe end forming mach does not replace the module during the bending process, which is "one tube and one mold". The "multi-tube one mode", that is, the pipe of the same diameter specification should try to use the same bending radius, that is, use the same set of modules to bend different shapes of tubes, which is conducive to reducing the number of modules.

The bending radius of the catheter determines the resistance of the catheter during bending. Generally speaking, the diameter of the pipe is large and the bending radius is small, the bending is prone to internal wrinkling and slipping, and the bending quality is difficult to ensure, and the R value of the bending die is generally selected to be 2 or 3 times the diameter of the pipe

The main influence of the bending forming speed on the forming quality is as follows: the speed is too fast, which is easy to cause the bending part of the pipe to be flat, and the roundness can not meet the requirements, resulting in the pipe pulling and breaking; If the speed is too slow, it is easy to cause the pipe wrinkling and the pressing block slipping, and the pipe with large diameter is easy to form the sag of the bending part of the pipe.

In the bending process, the mandrel mainly plays the role of supporting the inner wall of the bending radius of the conduit to prevent its deformation. At present, if the domestic pipe is bent and formed on the machine tool without the use of mandrel, its quality is difficult to guarantee. There are many forms of mandrel, such as column mandrel, universal single, double, three, four ball head mandrel, directional single, multi-ball head mandrel and so on. In addition, the position of the mandrel also has a certain impact on the bending of the conduit: in theory, its tangent line should be flush with the tangent line of the bending die, but a large number of tests have proved that 1 ~ 2mm in advance is better.
