Pressure wire drawing die good in lubrication

Abstract

The invention discloses a pressure wire drawing die good in lubrication. The pressure wire drawing die comprises a die base and a pressing bolt detachably arranged on the die base. A conical wire drawing die cavity is formed in the die base and internally provided with a conical wire drawing die body. The wire drawing die body is provided with a high-pressure lubrication cavity and a wire drawing hole. A pressure die is arranged in the pressing bolt and provided with a conical hole. The pressure die is arranged between the pressing bolt and the wire drawing die body. The pressing bolt is provided with a lubricating agent cavity used for containing a lubricating agent. The lubricating agent cavity communicates with the high-pressure lubricating cavity through the conical hole. According to the pressure wire drawing die good in lubrication, the steel wire surface friction force is reduced, the steel wire drawing force is reduced, and accordingly the purpose of improving the production efficiency is achieved.

Description

technical field [0001] The invention relates to the technical field of metal wire drawing, in particular to a well-lubricated pressure wire drawing die. Background technique [0002] Wire drawing machine, also known as wire drawing machine, refers to the wire rod with thicker wire diameter is drawn step by step by the drum wheel and eye mold of the wire drawing machine to make wire rod with thinner wire diameter. The metal wire is wound onto the wire drawing wheel by the feeding mechanism of the wire drawing machine, and a wire drawing die is arranged behind the wire drawing wheel. The surface of the wire drawing die in the prior art is easily scratched due to the effect of friction. The lubricating effect of ordinary wire drawing die is poor, and the steel wire directly contacts with the inner hole of the wire drawing die, which greatly reduces the life of the wire drawing die and affects the performance of the steel wire. Contents of the invention [0003] The present i...
