AI Technical Summary

Technical Problem

Existing hydraulic sheet metal bending machines are cumbersome, time-consuming, and labor-intensive when changing to different bending angles, making it difficult to meet the needs of rapid changeover production. Furthermore, the traditional bolt-fastening method for changing molds is time-consuming and labor-intensive.

Method used

A bending angle adjustment mechanism including an adjustment mechanism and a clamping mechanism was designed. The adjustment mechanism consisting of a first telescopic rod and a threaded rod achieves stepless adjustment, and the clamping mechanism with gear rack linkage and spring reset achieves quick engagement or release of the pressure plate.

Benefits of technology

It simplifies the angle adjustment process, improves processing efficiency and flexibility, significantly shortens mold changeover time, and enhances equipment efficiency.

Abstract

This utility model relates to the field of bending machine technology, specifically a bending angle adjustment mechanism for a hydraulic sheet metal bending machine. It includes a support frame, on which two sets of symmetrically distributed adjusting plates are rotatably mounted, and each set of adjusting plates is equipped with a pressure plate. The support frame is provided with an adjustment mechanism for adjusting the angle between the two sets of adjusting plates, and the adjusting plates are provided with clamping mechanisms for disassembling and assembling the pressure plates. The adjustment mechanism includes support rods located on the support frame and the adjusting plate support frame. By setting an adjustment mechanism composed of a first telescopic rod, a second telescopic rod, a threaded rod, and a threaded tube, the slider can be continuously and precisely driven to move, thereby changing the angle between the two sets of adjusting plates and achieving stepless adjustment of the bending angle. This mechanism is easy to operate, significantly reducing the complexity of angle adjustment, and eliminating the need for repeated machine stops, manual movement of the stop blocks, and multiple trial bends for correction.
