1. The evenly distributed machining allowance of the pipe bending machine die ensures stable and high productivity and safe bending process. When the angle is constant, the bending speed and feed rate can also be stably maintained at a high level. In this way, the change of die function and working load on the pipe bending machine is small, so there is less heat and fatigue, and then the die life of the pipe bending machine is improved.
2. One of the most important principles of the pipe bending machine die in the bending process is to create evenly distributed machining allowance for each bending in each bending process. That is to say, it is necessary to use bending dies with different angles. At any time, the primary pipe bending machine die should be as close to the final shape of the die as possible in each process.
z3. In order to obtain the longest service life of the pipe bending machine die, continuous cutting should be carried out for as long as possible in the bending process. If the number of dies entering the bending machine and exiting the bending machine is too short, it will be obvious. This will aggravate the thermal stress and thermal fatigue on the cutting edge. A uniform and high temperature in the cutting area is more favorable to the die of modern cemented carbide pipe bending machine than a large shake.
