Description

Technical Field

[0002] Sheet metal is a comprehensive cold processing technology for thin metal plates, including shearing, punching / cutting / compounding, folding, welding, riveting, splicing, forming, etc. Its most notable feature is that the thickness of the same part is consistent. Products processed by sheet metal processing are called sheet metal parts. Sheet metal parts are generally bent during processing, and a bending device is generally used during bending. When bending, the existing sheet metal bending mechanism generally uses a lifting mechanism to push the bending mechanism to slide on the surface of the shaft to perform stamping and bending processing on the sheet metal on the processing table. However, since the surface of the shaft does not have any cleaning and lubricating structure, the bending mechanism may not slide smoothly after a long period of sliding. For this reason, we propose a sheet metal bending mechanism. Utility Model Content
