The processing of pipe clamps requires bending. Each time the material is cut, it needs to be bent. The traditional bending machine positioner can only complete one bending process. After each bending, it needs to readjust the position and then bend for the second time. The process is complicated, the work efficiency is low, and the labor intensity of employees is high. In order to improve work efficiency, the workshop staff modified the original positioner and designed and manufactured a one-time multi-pass bending positioner.

The top of the plate is slidably connected with a vertically arranged push plate, which penetrates the plate in the vertical direction and is slidably connected with the sliding plate, and the push plate moves along the movement direction of the sliding plate. The utility model adopts the above technical scheme, when the upper die seat drives the push block to move downward, the push block pushes the sliding plate to move in the direction away from the bending lower die through the positioning block, and the spring is stretched; when the upper die seat drives the push block to move upward, the push block is separated from the positioning block, the spring rebounds, and the sliding plate returns to the initial position; by setting the spring, after the bending is completed, there is no need to manually push the sliding plate back to the initial position, so that the operation is convenient;
[0004] When the locator in this patent is bent, after the locator is positioned, one end of the pipe clamp is close to the positioning ruler, and four bending processes can be completed continuously at one time, and the pipe clamp processing can be completed quickly. It does not explain how to fix the pipe clamp. The existing structure for fixing and clamping it is relatively simple and cannot clamp and fix it well, thereby affecting the subsequent processing efficiency. Utility Model Content
