Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, and in particular to a quick-change stamping sheet metal stretching forming mechanism. Background Technology

[0002] Sheet stretch forming is a common metal processing technique, mainly used to manufacture parts of various shapes. It involves applying pressure to a sheet metal in a mold, causing it to undergo plastic deformation, thereby obtaining the desired shape.

[0003] Traditional stretch forming equipment typically uses a single mold structure. After one forming operation, the machine must be stopped for demolding and reloading, resulting in low production efficiency. In addition, metal shavings generated during the stretch forming process can easily remain inside the mold. If not cleaned in time, this can affect the surface quality of subsequent workpieces, and may even cause scratches or deformation of the products, reducing the yield rate. Summary of the Invention
