Description

Technical Field

[0001] The utility model relates to the technical field of punchers, in particular to a convenient-to-use puncher for processing oil seals. Background Art

[0002] Oil seals are generally divided into monomeric and assembled types. The assembled type means that the skeleton and lip materials can be freely combined and are generally used for special oil seals. Oil seals can be divided into various forms and named according to their sealing function, characteristics, structural type, working state and sealing mechanism. However, it is customary to call the rotating shaft lip seal an oil seal, and the seals used for static and dynamic sealing are called seals.

[0003] In the process of oil seal processing, punching is required, and a puncher is needed for punching. In the prior art, there are many kinds of such punchers. For example, the Chinese patent application No. 202321486982.0 discloses a convenient oil seal processing puncher, which is fixed by two clamping seats 8 during use. However, simply removing the two clamping seats 8 to clamp and fix the oil seal cannot be centered, which easily leads to the center position of the punched hole of the oil seal and the punching drill being out of concentricity. In this way, it is very troublesome to adjust the concentricity of the oil seal and the punching drill each time punching is performed, which is inconvenient to use and easily produces defective products. Therefore, in order to address this problem, an easy-to-use oil seal processing puncher needs to be improved. Utility Model Content
