Description

Technical Field

[0001] The utility model belongs to the technical field of polymer material processing, and in particular relates to a punching device for polytetrafluoroethylene. Background Art

[0002] Polytetrafluoroethylene is an excellent polymer material. It is a polymer obtained by polymerizing tetrafluoroethylene as a monomer. It has excellent heat resistance and cold resistance. Since the material is resistant to acid, alkali and various organic solvents, it will be used to make various workpieces. Polytetrafluoroethylene gaskets are one of them. When the existing polytetrafluoroethylene gaskets are processed, the polytetrafluoroethylene sheets are punched by punching equipment to form polytetrafluoroethylene gaskets. Although the existing device can produce polytetrafluoroethylene gaskets, it also has certain defects. For example, in the publication number "CN 219748268 U" discloses a stamping device for polytetrafluoroethylene. When the device is stamping a polytetrafluoroethylene sheet, the servo motor drives the screw to rotate, the screw drives the bottom block to slide in the bottom groove, and the bottom block drives the electric screw slide to move forward and backward. Therefore, when the device is punching, it can only move back and forth horizontally along a fixed path on the device, and cannot process other positions of the polytetrafluoroethylene sheet. Therefore, personnel need to repeatedly adjust the position of the sheet, and need to frequently disassemble and fix the polytetrafluoroethylene sheet, which increases the stamping difficulty of the device and reduces the stamping efficiency of the device.

The driving part 1 is moved to the top of the polytetrafluoroethylene sheet, and the stamping part 4 is driven downward by the driving part to allow the stamping part 4 to punch the polytetrafluoroethylene sheet to form a polytetrafluoroethylene gasket. The personnel remove the polytetrafluoroethylene gasket from the stamping part 4, and continue to drive the stamping part 4 to rotate by the driving part to rotate the stamping part 4 to another position, and repeat the above steps to punch the polytetrafluoroethylene sheet. When the polytetrafluoroethylene sheets on the support member 1 are all punched, the polytetrafluoroethylene sheets are driven to continue to move forward by the guide member 3, and the above steps are repeated to continuously process the polytetrafluoroethylene sheets.

[0033] Specifically, in one embodiment, regarding the support member 1:
