Treatment method for freezing and deburring inertial disc

Abstract

The invention discloses a treatment method for freezing and deburring an inertial disc, which comprises the following steps: S1, the inertial disc is poured into a container, and the container is driven to rotate, thereby driving the inertial disc to rotate together; S2, the inertial disc is cooled to reduce the temperature in the container to below -40 DEG C, so that the surface of the inertial disc is embrittled; S3, a shot blasting machine is used to spray particles to make the particles strike embrittled burrs on the surface of the inertial disc; S4: after completion, the inertial disc istaken out from the container. The invention greatly improves the cooling efficiency of the inertial disk by cooling the inertial disk through liquid nitrogen atomization, and achieves the embrittlement effect of burrs and improves the particle impact removal. By using the plastic particles, the surface damage of the zinc alloy inertial disc can be avoided, so that the roughness of the inertial disc will not be affected, and finally the rotational performance of the inertial disc in the whole belt assembly will be affected.

Description

technical field [0001] The invention relates to the field of industrial processing, in particular to a processing method for freezing and deburring an inertial disk. Background technique [0002] Most of the deburring methods for zinc alloy die-casting inertial discs use traditional manual deburring, vibration deburring, and shot blasting deburring; these three methods have certain disadvantages for inertial discs, and manual deburring is not only efficient Low, and there is manual uncertainty, it is easy to have omissions in deburring or deburring is not clean, so the product flows into the client and assembled on the car, the consequences are unimaginable; due to the special structure of the vibration research deburring, in some The vibrating stone at the corner cannot go in, resulting in poor deburring effect, and there will still be burrs remaining or burrs falling down and sticking to the surface of the product; although shot blasting deburring can remove burrs relative...
