Description

Technical Field

[0001] This utility model relates to the technical field of sealing component punching processing, and in particular to a guillotine-type punching device applied to the lip of a sealing component. Background Technology

[0002] When the lip of a seal has a long punch cut, it is generally processed by slicing or multiple-cut punching. Slicing involves first slicing the rubber with a slicing knife, and then cutting off the root connection with a cutting knife. Multiple-cut punching involves using a knife with a short blade to punch multiple times with multiple feeds to complete the punching of a long lip.

[0003] The scribing technique has the following drawbacks: When the scribing blade enters the rubber, the rubber at the end contracts before being cut. This contraction causes the cut to deviate, resulting in the cut at the end not being on a straight line with the subsequent cuts. The cut at the end appears to have taken a detour before returning to the correct path, causing the cut to be either not straight or have a "large end." Additionally, the scribing technique suffers from a relatively short blade life, especially for long cuts on thick rubber. The blade edge easily reaches its metal fatigue strength, becoming dull or chipping.

[0004] Multi-cutting technology has the following drawbacks: for example, there is a step at the joint between the first and second cuts, resulting in an uneven cut that affects aesthetics and adhesive bonding. Additionally, multiple feeds and multiple cuts increase the production time per piece, impacting cutting efficiency and overall production efficiency. Utility Model Content
