Abstract

The invention discloses an automatic processing unit for surface treatment and deburring of copper-chromium electric contact materials, which includes a magnetic grinding system, a grinding oil filtering system, a grinding oil cooling system, an auxiliary wind removal system, an oil mist collection system, and an oil dirt return system. system, automatic mechanical execution system and automatic electrical control system. The automatic processing unit of the present invention can well solve the bad defects such as surface cleanliness, surface structure state, edge state, and surface oxidation in the manufacturing process of copper-chromium electrical contact materials, and can produce high-quality and consistent copper-chromium contact materials. Head material, thereby reducing or eliminating the probability of the above-mentioned failure of copper chromium electrical contact material in the vacuum interrupter. Moreover, based on the processing technology of the automation unit, the process flow is short, the process connection is compact, and the automation level is high. It has high efficiency, environmental protection, and economical application value, and can be applied to batch industrial production.

Description

technical field [0001] The invention relates to the technical field of surface treatment of copper-chromium electrical contact materials, in particular to an automatic processing unit for surface treatment and deburring of copper-chromium electrical contact materials. Background technique [0002] Copper-chromium electrical contact material is currently considered to be the electrical contact material for high-voltage switches with the best comprehensive performance, and has been widely used. The copper-chromium electrical contact material is the "heart" part of the vacuum interrupter. During the manufacture, performance test and service of the vacuum interrupter, the surface cleanliness, surface structure state, edge state, The surface oxidation state, etc., play a vital role in whether it can be installed reliably, whether it can pass the performance test reliably, and whether it can continue to serve stably. Contact materials with high surface quality and high consistenc...
