Its production processes mainly include wire unwinding, wire drawing, annealing, painting, baking, cooling and wire winding. The quality of the finished enameled wire is mainly affected by the wire drawing and painting processes. According to survey statistics, the quality of the copper rod has an impact of more than 60% on the quality of the enameled wire.

[0003] During the production process of enameled wire, it was found that the outlet die seats of the wire drawing process were all installed externally, and the emulsion flushing effect was poor during the wire drawing process. After a long period of production, copper powder would accumulate on the wire drawing outlet die, locking bolts and the outer tower wheel of the wire drawing chamber. The copper powder accumulation would cause scratches on the surface of the copper rod wire on the one hand, and on the other hand, the copper powder would adhere to the surface of the bare copper wire, causing quality risks to the subsequent production of the enameled wire and significantly reducing the yield of the enameled wire. Therefore, we need to propose an enameled wire drawing die outlet mechanism. Utility Model Content
