When the curvatubi is working, the bending radius should be as far as possible to achieve "one pipe, one mold" and "multiple pipes, one mold". For 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". "Multiple pipes and one mold" means that pipes of the same diameter specification should use the same bending radius as much as possible, that is, use the same set of modules to bend different shapes of pipes, so as to help reduce the number of modules.
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, and the bending quality is difficult to guarantee. Therefore, the R value of the pipe bending die is generally 2-3 times the pipe diameter.
The main influence of the bending forming speed on the forming quality is: too fast speed will easily cause the flattening of the curved part of the catheter, and the roundness will not meet the requirements, causing the catheter to crack or break; too slow speed will easily cause the catheter to wrinkle and The compression block is slippery, and the pipe with a large diameter is easy to form a depression of the curved part of the catheter. For a large number of tests on these two CNC pipe benders, it is advisable to determine the bending speed of the pipe to be 20%-40% of the maximum bending speed of the machine.
