Automatic bending machine

Abstract

The invention discloses an automatic bending machine. The automatic bending machine comprises a workbench, a mounting frame, a bending tool and a first supporting plate, a V-shaped groove is formed inthe upper end face of the workbench in the left-right direction, the mounting frame is arranged above the workbench, the bending tool is arranged on the mounting frame in an up-down movable mode, andthe lower end of the bending tool is located over the V-shaped groove. When the bending tool moves downwards into the V-shaped groove, a steel wire framework above the V-shaped groove is forced to bebent to form a V-shaped structure. The first supporting plate is arranged on the front side of the workbench, and the end, away from the workbench, of the first supporting plate can rotate up and down around the end, close to the workbench, of the first supporting plate. When the first supporting plate rotates to the horizontal position, the upper end face of the first supporting plate is flush with the upper end face of the workbench. The steel wire framework of a horizontal net structure can be bent twice to form a C-shaped grid bridge frame, operation is easy, the working efficiency is high, the labor amount is small, and the situation that longitudinal ribs need to be bent in advance, and consequently the efficiency of welding operation is affected can be avoided.

Description

technical field [0001] The present application relates to the technical field of bending equipment, in particular to an automatic bending machine. Background technique [0002] At present, grid bridges are usually used for support and protection when laying cables, communication optical cables or other long and thin pipes. The existing grid bridge is generally a grid-like structure with a "匚"-shaped structure, and the inside of the "匚"-shaped structure can be used for laying cables, communication optical cables or other long and thin pipes. [0003] In the prior art, the processing method of the grid bridge frame of the "匚"-shaped structure is: firstly, the longitudinal ribs are bent to form the "匚"-shaped structure, and then the longitudinal ribs and the transverse ribs of the "匚"-shaped structure are arranged to form a network Grid structure, and finally weld the junction of transverse ribs and longitudinal ribs. [0004] However, the above-mentioned processing method ma...

AI Technical Summary

Problems solved by technology

[0004] However, the above-mentioned processing method mainly has the following disadvantages: 1. Due to the need to bend each longitudinal rib in advance to form a "匚"-shaped structure, the amount of operation is large and the bending efficiency is low; 2. Since the longitudinal rib is in the shape of "匚" structure, when the longitudinal ribs and transverse ribs are arranged to form a grid structure, the longitudinal ribs need to be supported and fixed, and the operation is cumbersome; moreover, the supporting parts and the longitudinal ribs themselves are likely to interfere with the welding equipment, thereby affecting the welding operation work efficiency
