[0002] The gasket has the properties of oil resistance, acid and alkali resistance, cold and heat resistance, and aging resistance. It can be directly cut into sealing gaskets of various shapes and is widely used in the pharmaceutical, electronics, chemical, antistatic, flame retardant, food and other industries.

[0003] Gaskets serve as mechanical seals between two workpieces, and are usually used to prevent leakage caused by pressure, corrosion, or thermal expansion and contraction between the two workpieces. During the production of rubber gaskets, a driving structure is generally used to drive a punching head to punch the rubber sheet, thereby forming an annular gasket. In order to increase production, rubber gaskets are usually punched out from a whole piece of sheet material during production. However, when using traditional punching equipment to perform punching operations, manual intervention is often required to feed and fix the raw materials, which not only leads to a significant increase in labor costs, but also affects stamping efficiency and poses a certain threat to personal safety. More importantly, manual handling lacks sufficient stability, dimensional accuracy, and stability, which affects stamping accuracy and is also very likely to cause pollution and waste of raw materials.
