Embodiment

[0016] Embodiment: The present invention provides a kind of electrical contact deburring cleaning and polishing process, comprising the following specific steps:

[0017] S1: Initial cleaning: Put the electrical contacts in a basket with a mesh structure, soak the basket in a pool with cleaning agent for 20-30 minutes, control the temperature of the water in the pool at 35°-40°, after soaking, use Rinse the cleaning agent on the surface of the electrical contacts in the basket with flowing water, and then heat-treat the cleaned electrical contacts. In a vacuum environment, control the temperature at 80-150°C and heat-treatment time for 20-30 minutes to remove residues. organic matter;

[0018] S2: Polishing: put the heat-treated electrical contacts into the polishing machine, use coarse wax water, adjust the speed of the polishing machine to 2500r / min for rough polishing for 15-20min; use medium and coarse wax water, adjust the speed of the polishing machine Polish at 4800r / m...

Abstract

The invention discloses a deburring, washing and polishing process for an electrical contact. The deburring, washing and polishing process comprises four steps, including primary washing, polishing, secondary washing and after-treatment; the deburring, washing and polishing process disclosed by the invention is simple to operate and low in defective percentage; in a primary washing process, oil stain impurities on the surface of the electrical contact can be removed by adopting heat treatment and warm water and flowing water added with a detergent; subsequently the surface of the electrical contact is polished by means of coarse polishing, intermediate polishing and fine polishing, so that the glossiness of the polished surface of the electrical contact can be greatly increased; tiny scratches on the polished surface of the electrical contact can also be effectively eliminated; a good polishing effect is achieved; meanwhile environment-friendly polishing liquid is adopted, no pollutionis generated; a good surface treatment effect is achieved; secondary washing is implemented by adopting dry ice; dry ice particles are directly jetted to the surface of the electrical surface and areinstantly sublimated; the problem about secondary pollution is prevented; meanwhile a drying step is not needed; the work efficiency is high; washing and further polishing of the surface of the electrical contact can be implemented simultaneously; and the polishing effect is improved.

Description

technical field [0001] The invention relates to the technical field of electric contact production, in particular to an electric contact deburring, cleaning and polishing process. Background technique [0002] Contact materials are electrical contact materials used for switches, relays, electrical connections and electrical connector components, also known as electrical contact materials, generally divided into two types: contact materials for strong electricity and contact materials for weak electricity. In switching electrical appliances, electrical contacts directly undertake the function of breaking and connecting circuits and carrying normal operating current or carrying overload current within a certain period of time. The key functions of various electrical appliances, such as the on-off capability of power distribution appliances, control electrical appliances The electrical life of the relay and the reliability of the relay all depend on the working performance and ...
