One-step forming method for high-low pressure bidirectional high-strength oil seal

Abstract

The invention discloses a one-step forming method for a high-low pressure bidirectional high-strength oil seal. According to the method, a T-shaped outer framework and a vertical inner framework are arranged. The method comprises the following steps that A, the T-shaped outer framework and the vertical inner framework are positioned, so that the vertical inner framework and a vertical rod of the T-shaped outer framework are located on the same straight line, and a gap is reserved between the vertical inner framework and the vertical rod of the T-shaped outer framework; B, rubber and bone glue are injected for vulcanization, the T-shaped outer framework and the vertical inner framework serve as the center, wrapping forming is carried out, forming comprises a low-pressure end and a high-pressure end, and the low-pressure end and the high-pressure end are located on the two sides of the vertical inner framework correspondingly; C, a supporting ring is clamped into the inner side surface of the high-pressure end; and D, the outer surfaces of the low-pressure end and the high-pressure end are arranged and clamped into an annular spring body. The method is reasonable, low-pressure oil seal and high-pressure oil seal forming can be completed at a time, the machining efficiency can be conveniently improved, so that the machining cost can be lowered during use, in addition, the integrated structure is adopted, the high-pressure sealing performance can be improved, and practicability is high.

Description

Technical field[0001]The present invention belongs to the technical field of oil sealing processing, and more particularly to a high and low pressure bidirectional high strength oil seal primary molding method.Background technique[0002]The high and low voltage bidirectional oil seal structure in the prior art is composed of two oil seals different from the traditional and imported oil seals. One seal high pressure, one seal low pressure, two assembly, corresponding cost is higher At the same time, the problems in the assembly link are relatively, so applicability and practicality are limited.Inventive content[0003]It is an object of the present invention to provide a high and low pressure bidirectional high strength oil seal primary molding method.[0004]A technical solution to the object of the present invention is a high and low pressure bidirectional oil seal primary molding method, including a T-shaped outer backbone and a vertical inner backbone, including the step of: Step A, p...

AI Technical Summary

Problems solved by technology

[0002] The structure of high and low pressure bi-directional oil seals in the prior art is based on the traditional and imported oil seals, which are composed of two oil seals with different functions when used. One seals high pressure and the other seals low pressure. It needs to be assembled twice, and the corresponding cost is relatively high. , and there are relatively many problems in the assembly process, so the applicability and practicality are limited
