Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal part edge folding, in particular to a sheet metal part edge folding mechanism. Background Art

[0002] Sheet metal flanging refers to the process of bending, curving or curling the edge of a metal sheet to form a specific edge shape during sheet metal processing. This process can be completed by mechanical equipment such as a bending machine, a rolling machine, etc. An existing automotive sheet metal shaping and flanging mechanism (publication number: CN211386455U) has at least the following defects in use:

[0003] When bending, if a larger sheet metal part needs to be bent, the sheet metal part needs to be broken first, and then the sheet metal part needs to be folded. Such separate operations take a long time and are cumbersome to operate. Therefore, a sheet metal folding mechanism is proposed. Utility Model Content
