How to replace the mold of CNC pipe bender

There are many industries in which China pipe bending machines are applied, mainly in the decoration industry, automobile industry, electric power construction, railway construction, boilers, bridges, ships, and pipeline laying and transformation. The correct operation of the China pipe bending machine can ensure the personal safety of the operators and is very helpful to prolong the service life of the China pipe bending machine. The bend not only avoids the collision between the trolley and the die, and ensures the smooth completion of the last bend, but also reduces the clamping loss of the material head and reduces the production cost.

　　 The pipe bending head of the China pipe bending machine can move horizontally along the guide rail. This is necessary for the China pipe bending machine to adjust the pipe groove of the bending die to align with the centerline of the machine tool after the bending die is replaced. This is simpler than adjusting the centerline of the machine tool by adjusting the guide rail and tailstock on the bed. When the China pipe bending machine is bent, because the trolley is used as a load, it is pulled forward by the pipe. In order to improve the bending, avoid excessive thinning of the wall thickness of the bent part of the pipe, reduce springback, and increase the booster device. When bending, the die not only compresses the tube, but is also pushed forward by the thrust to form a side thrust to help the bending. The pipe bending arm and the bending spindle are connected into one body, the pipe bending die axis can be replaced, and the clamping die moves up and down. This not only has a reasonable structure, increases the strength of the mechanical part, but also has a simple structure, which simplifies the electrical circuit.

　　The trolley that completes the straight-line feeding motion (DBB) is pulled forward by the pipe during the bending process of the pipe. In this way, the “positive thrust” is removed, thereby eliminating the problem of synchronization between the trolley and the bending speed, and the negative feedback system of the DC motor set to increase the “positive thrust” is removed, and the electrical circuit is simplified. Since the positive thrust is beneficial to the bending of the tube, especially when the tube with a larger diameter is bent, the positive thrust is necessary. Therefore, the VB China pipe bending machine adds a booster device.
