A multi-point fixing device for a thick metal plate bending machine

Abstract

The invention discloses a multi-point fixing device of a thick metal plate bending machine. The multi-point fixing device comprises a conveying table and a bending device, supporting legs are fixedlyarranged on the edge, close to the front side, of the lower surface of the conveying table, the bending device is fixedly arranged at the rear end of the conveying table, and supporting cylinders arefixedly arranged on the two sides of the upper surface of the bending device in the vertical direction. According to the multi-point fixing device, an electric push rod and a sliding plate are arranged to be matched with each other, the thick metal plate pieces are pushed to the bending device in a sliding mode, labor is saved, and efficiency is improved; a connecting spring is arranged, so that afixing rod piece and a sliding rod piece can clamp the metal plate in the horizontal direction, a plurality of L-shaped fixing devices are arranged, the metal plates are fixed in the vertical direction, dislocation is avoided, and the bending line is inclined; and an anti-skid pad is arranged at the lower end of fastening nuts, a pressing mark is prevented from being left on the metal plate, a thin plate is additionally arranged in pressing grooves, so that the width of the pressing grooves is narrowed, and then the bending angle can be adjusted.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a multi-point fixing device for a thick metal plate bending machine. Background technique [0002] A bending machine is a machine capable of bending thin plates, and its structure mainly includes a bracket, a workbench and a clamping plate. The bending machine is an important equipment for bending and forming workpieces in the sheet metal industry. Its function is to press steel plates into parts of various shapes according to the needs of the process. But it still has the following disadvantages in actual use: [0003] 1. The bending machine needs to manually push the plate to the lower end of the bending device when bending. The bending of a large number of thick metal plates is intensive, time-consuming and labor-intensive, and the efficiency is low; [0004] 2. When bending, the fixing of the thick metal plate is also fixed manually, and the plate is placed un...

AI Technical Summary

Problems solved by technology

[0003] 1. The bending machine needs to manually push the plate to the lower end of the bending device when bending. The bending of a large number of thick metal plates is intensive, time-consuming and labor-intensive, and the efficiency is low;

[0004] 2. When bending, the fixing of the thick metal plate is also fixed manually, and the plate is placed unevenly, which may easily lead to the inclination of the bending line;

[0005] 3. The width of the press groove of the bending machine cannot be adjusted. For metal plates of different thicknesses, the bending angle cannot be adjusted by adjusting the width of the press groove
