Description

Technical Field

[0001] The utility model relates to the technical field of stamping and forming mechanisms, in particular to a stamping and forming mechanism for producing sheet metal parts. Background Art

[0002] Sheet metal parts are products manufactured through sheet metal processing. They are typically formed into the desired shape and size by plastically deforming thin metal sheets through manual or die stamping. Stamping mechanisms are key equipment in sheet metal production, using pressure to press sheet metal into specific shapes. This process is suitable for high-volume production because it can quickly and accurately replicate identical part shapes.

[0003] Dust and impurities will adhere to the inside of the forming mold. These pollutants come from particles on the surface of the raw materials, dust in the working environment, lubricant residues or debris generated by mold wear. Dust and impurities adhere to the inside of the mold. These foreign objects will be embedded in the sheet metal material during the stamping process, resulting in surface defects, inaccurate dimensions or affecting the forming quality of the material. The conventional cleaning method is to wipe it with a rag, which is more troublesome. For this reason, a stamping forming mechanism for sheet metal production is proposed. Utility Model Content
