A Processing Technology of Precision Gap Adjusting Gasket

Abstract

The invention discloses a processing technology of a precision gap adjusting gasket. (1) select raw materials for overall lamination, record the thickness of lamination and select a tool; (2) fix the lamination parts as a whole with screws, and calculate the fixed torque value according to the yield strength of the materials of the lamination parts The size of Y; (3) the inner and outer diameter of the tooling fixture to fix the laminated parts; (4) CNC machining the inner and outer diameters of the laminated parts; (5) cleaning the surface; (6) packaging and storage. The invention has the advantages of automatic production without moulds, avoiding technical difficulties and cost investment in traditional mold opening; no burrs, flanging, and other quality problems in the processing process, high precision and high efficiency; and low cost control.

Description

technical field [0001] The invention relates to a precision mechanical processing technology, in particular to a processing technology of a precision gap adjusting gasket. Background technique [0002] At present, gaskets with lower quality requirements in the market generally adopt ordinary die stamping technology; while precision gap adjustment gaskets with higher quality requirements generally adopt precision die stamping methods, wire cutting, water cutting, laser cutting and other technologies, but the parts are deformed , burrs, surface discoloration risk is very high. For high-precision gaskets and gap adjustment gaskets with very high quality requirements, especially in the face of harsh requirements such as no burrs, the above-mentioned related methods are all ineffective, so a very expensive high-precision composite mold stamping process has to be used. In order to ensure that the fracture of the ultra-thin gasket is free of burrs, it is necessary to require a sma...

For high-precision gaskets and gap adjustment gaskets with very high quality requirements, especially in the face of harsh requirements such as no burrs, the above-mentioned related methods are all ineffective, so a very expensive high-precision composite mold stamping process has to be used

In order to ensure that the fracture of the ultra-thin gasket is free of burrs, it is necessary to require a small die gap or even a zero die gap to be blanked at high speed and high frequency using interference fit. This method has very high requirements for die steel, and currently there are Certain limitations, can only be replaced by some steel with similar properties but wears out relatively quickly

In addition, die blanking has certain limitations on the parts to be processed, and the humanization is extremely poor, such as the single processing volume cannot be lower than the required value, cannot be easily transformed, and cannot be processed in various types, otherwise the product will be greatly increased.
