Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, and in particular to an automotive sealing strip punch. Background Technology

[0002] As a critical sealing component of the automotive body, the drilling precision of automotive sealing strips directly affects assembly quality and sealing performance. Traditional drilling technology faces two major challenges: first, the rubber material is prone to deformation during stamping, leading to hole misalignment; second, the complex equipment structure makes it difficult to adapt to flexible adjustments of various hole spacings. Existing solutions mostly use fixed stamping modules, which are not only inefficient to replace but also prone to secondary pollution due to waste accumulation.

[0003] The existing application number CN202322293951.X proposes an automotive sealing strip punch, which includes a base plate, a drive assembly and an opening assembly. Two sets of side plates are fixedly installed on the top of the base plate, and a top plate is fixedly installed on the top of the two sets of side plates. This automotive sealing strip punch can be raised and lowered, making it easier to punch holes in automotive sealing strips during processing. This punching method reduces manual intervention steps and the workload of workers. After punching, the punch can be moved to remove sealing strip waste that is clogging the inside of the punch. This not only avoids the problem of poor punching effect due to excessive waste inside the punch after prolonged use, but also reduces the cleaning time for workers. While increasing the punching effect, it further reduces the labor intensity of workers. However, the existing technology still has the problem of sealing strip misalignment during the punching process, especially during high-speed stamping. Insufficient clamping force causes the sealing strip to shift, which affects the hole position accuracy and product consistency. In addition, the waste generated during the punching process tends to accumulate in the stamping area, affecting the accuracy of subsequent processing. Utility Model Content
