Manufacturing method of power distribution switch cabinet

Abstract

The invention relates to a manufacturing method of a power distribution switch cabinet. The manufacturing method uses bending and tapping equipment, the bending and tapping equipment comprises a base, a feeding and bending device and an alignment and tapping device, the feeding and bending device is arranged at the upper end of the base, and the alignment and tapping device is arranged at the rear side of the upper end of the base. According to the manufacturing method, when the pressure is maintained after a plate is bent, a drilling device is used for drilling and tapping the bent edge of the plate, and the bending, pressure maintaining and drilling and tapping operations are integrated into one process, so that the production time of the power distribution cabinet is saved to a great extent, the problem of low production efficiency of the power distribution cabinet is solved, meanwhile, in the pressure maintaining operation, the plate is clamped and fixed in a high-strength mode, and therefore the hole position for hole forming at the moment is more accurate.

Description

technical field [0001] The invention relates to the technical field of power distribution cabinet production, in particular to a method for manufacturing a power distribution switch cabinet. Background technique [0002] The power distribution cabinet is a general term for the motor control center. The power distribution cabinet is used in the occasions where the load is relatively scattered and there are few circuits; the motor control center is used in the occasions where the load is concentrated and there are many circuits. They distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearest load. This level of equipment shall provide protection, monitoring and control of the load. The switchboard box should be made of non-combustible materials; open switchboards can be installed in production sites and offices with low risk of electric shock; [0003] When making a power distribution cabinet, the board is often bent f...

AI Technical Summary

Problems solved by technology

[0003] When making a power distribution cabinet, the board is often bent first and then punched, and then the board and the skeleton are spliced. In this process, there are often the following problems. First, because the board often returns due to its metal memory after bending Therefore, it is necessary to carry out pressure-holding treatment on the bent plate. If the hole is drilled after the pressure-holding process, the production time of a single plate will be greatly extended, and the production efficiency of the power distribution cabinet will be greatly reduced.
