The practicability of the front support (pipe clamp) of the metal pipe bending machine

The part to be bent of the pipe is transported by the feeding mechanism to the pipe bending die set at the front end of the tube and pipe bending machine for pipe bending processing. Because the middle part of the pipe fitting is easy to bend downward due to the influence of its own weight, in the process of forward feeding, the pipe fitting is prone to drift and sway, and it is difficult to accurately reach the bending die.

When the piece in Figure 1 enters the state shown in Figure 2 after completing the front coil, the center of gravity is tilted forward. When the clamping die is released, the gripping clip falls behind the gravity image. At this time, if the pipe is bent again, the pipe will be clamped or the clamp will not be clamped. quasi and so on. This can be avoided by increasing the front support.

There are two commonly used methods of supporting materials. Lifting the supporting materials is mostly used for thicker pipe fittings. It is used for holding the material and holding the thin tube to prevent deformation. Therefore, it is recommended to use the front support mechanism when the pipe bend is complicated or too long. When the end of the pipe is clamped and moved forward, there will be interference between the front support and the clamping jaw. If the front support is closed prematurely, the pipe will collapse. For this problem, different systems have different solutions. One is to set the opening position of the bracket: input the relevant numerical value and the support will drop or open when the trolley moves to the specified position, so that the trolley can pass normally. The other is through the induction switch. When the trolley triggers the induction switch, the front support material will automatically retract.
