Power copper contact lost wax investment casting
In the field of high voltage switch parts processing technology, a processing method of high voltage switch copper contact, contact finger and contact holder parts is specifically disclosed.
The processing method is as follows: melting: adding electrolytic copper plate and old material to the induction furnace, then covering with charcoal, then heating and melting electrolytic copper plate, adding phosphor copper before the oven for final deoxidation; Heat preservation: Transfer the molten liquid obtained in step one to the heat preservation furnace for heat preservation storage, and carry out full slagging;
Pouring extrusion steps: First preheat the extrusion mold, then pour the molten liquid into the cavity of the extrusion mold, open the press down, and directly extrude the liquid to produce the billet; High voltage switch copper contact, contact finger, contact holder parts are made by machining the blank. The processing method of the invention adopts solidification crystallization molding technology under pressure, has short process flow, high material utilization rate, excellent product performance and low production cost.
