Abstract

The invention belongs to the technical field of mechanical processing of sealing rings, and in particular relates to a processing method and tooling for special-shaped sealing rings, which process an 8-shaped groove on a raw material plate, and use the inner surface and outer surface of the groove as the reference roughness. The prototype of the special-shaped sealing ring is milled out, and the inner surface of the prototype of the special-shaped sealing ring is fine-milled to the required size, and then the inner cavity is filled with a process pressure plate, and the outer surface is fine-milled to obtain the finished product of the special-shaped sealing ring. Plate and process platen are clamped at one time, divided into rough milling and fine milling, which effectively solves the problem of difficult positioning and clamping when processing fluoroplastic special-shaped sealing rings, and its positioning is accurate, and the processing error of special-shaped sealing rings is small. High efficiency ensures the sealing performance of the special-shaped sealing ring.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing of sealing rings, and in particular relates to a processing method for a special-shaped sealing ring, a process pressure plate and a positioning plate for processing. Background technique [0002] Gasket is a kind of sealing spare parts used in machinery, equipment and pipelines where there is fluid, and it plays a sealing role. Gaskets are made of metal or non-metal plate-like materials through cutting, stamping or cutting processes, and are used for sealing connections between pipes and between parts of mechanical equipment. According to the material, it is divided into metal gaskets and non-metal gaskets. [0003] PTFE material, high temperature resistance, ozone resistance, natural aging resistance, vacuum resistance, fuel oil resistance, lubricating oil resistance, strong oxidant resistance, widely used in national defense industry and civil industry. The special-shaped protec...
