An automatic bending machine

Abstract

The application discloses an automatic bending machine, which includes a workbench, a mounting frame, a bending tool and a first pallet. The upper end surface of the workbench is provided with a V-shaped groove along the left and right directions, and the mounting frame is arranged above the workbench. The bending tool can be moved up and down on the mounting frame, and the lower end of the bending tool is located directly above the V-shaped groove; when the bending tool moves down into the V-shaped groove, the steel wire skeleton above the V-shaped groove can be forced to bend. Fold to form a V-shaped structure; the first pallet is arranged on the front side of the workbench, and the end of the first pallet far away from the workbench can rotate up and down around the end of the first pallet close to the workbench; when the first pallet rotates When reaching the horizontal position, the upper end surface of the first supporting plate is flush with the upper end surface of the workbench. It can bend the steel wire skeleton of the horizontal mesh structure twice to form a "匚"-shaped grid bridge frame, which is easy to operate, high in work efficiency, and small in labor, and can avoid the need to bend the longitudinal ribs in advance and affect the welding operation. efficiency.

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...

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
