Description

Technical Field

[0001] The present application relates to the field of sheet metal bending, and in particular to a sheet metal bending device for mechanical production. Background Art

[0002] "Mechanical production" refers to the process of producing items through mechanical equipment and process flow. This process usually involves a series of processing, assembly, inspection and other steps of raw materials or semi-finished products to finally produce finished products. Existing mechanical raw material plates need to be processed into different shapes. Bending is also a common sheet metal processing technology, which is used to bend metal sheets into the required shape according to design requirements. This process is usually used to manufacture various metal components and parts, such as chassis, housings, brackets, etc.

[0003] When bending sheet metal, due to the certain mass of the metal sheet, the sheet metal as a whole will warp at a certain angle during the bending process. However, some longer sheets may produce a certain degree of bending deformation when they are warped, thereby affecting the overall flatness of the sheet metal surface, which has a certain impact on the subsequent processing and use of the sheet metal, and reduces the overall utilization efficiency of the sheet metal.

[0004] In view of the above-mentioned related technologies, the inventor believes that the sheet metal has the defect of bending deformation during the bending process, and therefore proposes a sheet metal bending device for mechanical production to solve the above-mentioned problem.
