Description

Technical Field

[0002] With the development of modern industry, distribution boxes, as core components of power distribution and control, are increasingly widely used, covering multiple fields such as buildings, industrial plants, data centers, and new energy facilities. In the production process of distribution boxes, the bending of sheet metal parts is an indispensable link, and the bending machine, as the core equipment in this link, directly determines the quality and production efficiency of the distribution box. The sheet metal bending machine for electrical distribution boxes is mainly used for bending sheet metal parts of electrical distribution boxes and other power equipment. After bending, these sheet metal parts can form key components such as the outer shell, bracket, and panel of the distribution box, meeting the structural design and functional requirements of the distribution box.

[0003] Currently, the common electrical distribution box bending machines on the market mainly consist of a machine body, hydraulic system, worktable, upper die and lower die. The core lies in the cooperation of the upper die and lower die. The worker places the metal on the worktable and the metal sheet is bent into shape by the closing of the upper and lower dies. The hydraulic system provides power to make the upper die move in the vertical direction, apply pressure to the metal, and then fold the metal upward to complete the bending operation. However, this device still has some shortcomings.

[0004] Traditional sheet metal bending machines for electrical distribution boxes require manual bending operations after hydraulic pressure is applied. This process is time-consuming and labor-intensive, and it can easily threaten the safety of workers. During the manual loading process, the metal sheets are prone to shifting, which can affect the finished product. Utility Model Content
