Description

A bending device for power distribution cabinet production

Technical Field

The utility model belongs to the technical field of power distribution cabinet production equipment manufacturing, and in particular relates to a bending device used for power distribution cabinet production.

Background Art

The bending device generally bends the metal sheet during the production process of the distribution cabinet. In order to enhance the sealing effect and structural stability of the finished distribution cabinet, the distribution cabinet shell is usually made of a whole sheet. The cold-rolled metal sheet is bent by the bending device and then assembled into the distribution cabinet shell.

Common sheet metal bending devices perform bending operations by placing the sheet metal into the bending operation area of a bending machine. However, the bending mechanism in conventional sheet metal bending devices generally simply clamps the metal sheet metal and then directly folds the sheet metal, which makes it difficult to ensure the processing accuracy of the bending operation. During the production process, the metal sheet metal needs to be clamped to prevent the metal sheet metal from shifting and affecting the processing accuracy. Conventional sheet metal bending devices usually use screws to fix the sheet metal, and the clamping effect is poor. After bending, the sheet metal needs to be taken out and punched for subsequent installation. The handling process reduces the efficiency of production and processing.
