In order to ensure convenient installation and maintenance, the general end covers are formed by sheet metal deep drawing The side of the deep-drawing part is designed with 3 to 4 outer protrusions, which are used for interference fit with the groove at the end of the sealing shaft, and are used to clamp the end cover. At present, the outer convex hull of the end cap is usually formed by a combination of vertical convex hull pressing and indexing. As a result, it is difficult to ensure the position of 3 to 4 convex hulls, and the extruded convex hulls are not uniform in size, resulting in inconsistent tightness after assembly. ; If polyurethane rubber is used to expand the shape, due to the small size of the convex hull and the excessive unit pressure, it is not easy to realize; because this type of mold forming must be implemented on a mechanical press, the noise is large and the cost is high.
