Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal processing, in particular to a multifunctional clamp for sheet metal processing. Background Art

[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. The products processed by sheet metal technology are called sheet metal parts. The sheet metal parts referred to in different industries are generally different, and are mostly used for assembly. Before the sheet metal parts are used, it is usually necessary to drill multiple connecting holes on the sheet metal parts for screws to connect each other. A punching device is required in the drilling process.

[0004] Although the device can drive the two clamping rods to move down at the same time through the transmission device, so as to clamp the two sides of the sheet metal, and clamp the sheet metal by mechanical transmission, the clamping force can be improved, the sheet metal can be prevented from loosening, and the subsequent drilling quality can be improved, and the metal residue collected in the placement groove can be pushed out by the pushing mechanism, which is convenient for subsequent use, and after the handle is released, the push plate can be reset under the action of the spring to facilitate pushing again.
