Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, in particular to a laser-perforated tire membrane of a passenger car bumper. Background Art

[0002] The passenger car bumper is a safety device that absorbs and mitigates external impact forces and protects the front and rear parts of the car body. During the processing of the passenger car bumper, drilling operations are required to facilitate later installation. Therefore, a perforated tire membrane is required to fix the passenger car bumper to ensure the accuracy of laser drilling.

[0003] The existing laser perforated tire membrane for passenger car bumper processing can only be used for the fixed punching of passenger car bumpers of specific specifications. When punching operations are required for passenger car bumpers of other specifications, it is necessary to re-customize the matching laser perforated tire membrane. The customization process is time-consuming and has limitations in use. Utility Model Content
