Process for machining positioning gasket

Abstract

The invention discloses a process for machining a positioning gasket. The process comprises the following steps of: 1, performing finish turning, namely performing the finish turning on an excircle and an inner hole of a raw material until the sizes of the excircle and the inner hole reach design sizes; 2, performing heat treatment; 3, performing wire cutting; 4, grinding, namely clamping a workpiece by using a double-sided grinding fixture, grinding the plane of the workpiece until the size of the workpiece reaches the design size, and keeping depth of parallelism, planeness and surface roughness; 5, performing finish-milling, namely milling positioning holes in the workpiece according to the requirement of a drawing; 6, performing aging, namely keeping the workpiece in a drying oven at the temperature of 140 DEG C for 12 hours; 7, polishing, namely polishing the surface of a part by using a magnetic force polishing machine without bumping and scratching, and demagnetizing the part by using a demagnetizing machine; and 8, packaging for warehousing. Due to the adoption of the process, the positioning gasket can be machined quickly and efficiently and is high in accuracy, the utilization rate of materials is high, cost is saved, and machining efficiency is improved.

Description

technical field [0001] The invention relates to the field of gasket processing, in particular to a processing technology for positioning gaskets. Background technique [0002] A gasket is a mechanical seal between two objects, usually to prevent pressure, corrosion, and natural expansion and contraction of pipelines between the two objects; since the machined surface cannot be perfect, it can be filled with gaskets Irregularity, the structure of the positioning gasket is complex, the precision requirement is high, the utilization rate of traditional gasket processing materials is low, most of them are processed individually, the production efficiency is low, and the accuracy and qualification rate of the product are relatively low. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a processing technology for the positioning gasket, which can process the positioning gasket quickly and efficiently, has high prec...
