Specific process process of rubber skeleton oil seal production
The rubber skeleton oil seal generally refers to the shaft lip -shaped seal, also called axis seal. In addition, there are rubber skeleton oil seals that are moved backward, such as shock absorber oil seal and valve stem oil seal. There are also oil seals between the rubber skeleton oil seal and the rubber skeleton oil seal of the reciprocated movement, that is, the rubber sealing parts have both rotating and reciprocating skeleton oil seals, such as hydraulic motors and ultra -high pressure oil seals on the direction.
There are many forms of excellent chinese rubber oil seal, in addition to built-in skeleton oil seal, exposed skeleton oil seal, prefabricated double skeleton oil seal and so on. In addition, the skeleton without rubber oil seal and spring-free oil seal also belong to the scope of oil seal. Its process flow chart can remove the skeleton, adhesive, spring or an unnecessary process link. In addition, some oil seals such as the exposed frame oil seal of the assembly are also assembled during trimming. Some need to spray paint on the side wall of the metal frame; some oil seals need to inject lubricating oil into the auxiliary lip.
For oil seals used in some special occasions, such as requiring to increase abrasion resistance and reduce friction coefficients, it should also be carried out in the halogen liquid before hanging spring. Polytetrafluoroethylene film, so the surface treatment and adhesion process of polytrafluoroethylene should be added to the process.
