Description

Technical Field

[0001] The utility model relates to the technical field of punching devices, in particular to a punching device for sealing members. Background Art

[0002] Automotive seals play a vital role in the automobile manufacturing process. They can prevent moisture, dust and other impurities from entering the key components of the car, thereby ensuring the normal operation of the car. They are mainly used in car doors, trunks, glass and other parts to improve the sound insulation and waterproof performance of the car. During the processing of automotive seals, it is necessary to perform punching operations according to processing requirements. After the traditional punching device completes the punching operation of the seal, the remaining waste during the punching process is easily left in the punching operation groove, which is not only inconvenient for centralized collection and treatment of the waste, but also too much waste remaining in the operation groove will affect the subsequent punching operation of the seal. To this end, we propose a punching device for seals. Utility Model Content
