Die interior oil gas lubricating mechanism of WDC440301 type wire drawing machine

Abstract

The invention relates to the technical field of metal wire drawing, in particular to a die interior oil gas lubricating mechanism of a WDC440301 type wire drawing machine. Inner dies of the wire drawing machine and an oil gas supply station are included. The inner dies of the wire drawing machine are arranged in a wire drawing cavity in rows at intervals through die bases. The part, between everytwo adjacent die bases, of the wire drawing cavity is internally provided with a free rotating flywheel. A metal wire sequentially penetrates through the inner dies, and the metal wire between the adjacent inner dies is wound around the flywheels by one circle. A nozzle is arranged on the side edge of each die base, wherein the nozzle is connected with the oil gas supply station through an oil gasconveying pipeline, and oil gas sprayed out of the nozzle is sprayed to the corresponding inner die or sprayed to the metal wire which is about to enter the corresponding inner die. By means of the obtained die interior oil gas lubricating mechanism of the WDC440301 type wire drawing machine, the inner dies of the wire drawing machine can be effectively and accurately cooled, it is ensured that wire drawing oil can be sprayed to wire drawing friction faces of the inner dies, the cooling effect and the wire drawing effect are ensured, and meanwhile the usage amount of the wire drawing oil canbe greatly reduced.

Description

technical field [0001] The invention relates to the technical field of metal wire drawing, in particular to an in-mold oil-air lubrication mechanism of a WDC440301 wire drawing machine. Background technique [0002] In the prior art, when the wire drawing machine draws the metal wire, friction occurs between the metal wire and the mold, thereby generating a large amount of heat energy, which makes the temperature of the mold and the wire rise. However, the current lubricating method of the wire drawing machine for the mold is Shower lubrication, this method is that the flywheel rotates during the drawing process to throw the drawing oil in the drawing cavity and splash it randomly on the surface of the mold to cool the mold. The amount of drawing oil that can enter the internal friction surface of the mold is inaccurate. And the arriving position is also uncertain, so it is easy to cause excessive heat generation of the mold and cause wire breakage, and the life of the mold ...

[0002] In the prior art, when the wire drawing machine draws the metal wire, friction occurs between the metal wire and the mold, thereby generating a large amount of heat energy, which makes the temperature of the mold and the wire rise. However, the current lubricating method of the wire drawing machine for the mold is Shower lubrication, this method is that the flywheel rotates during the drawing process to throw the drawing oil in the drawing cavity and splash it randomly on the surface of the mold to cool the mold. The amount of drawing oil that can enter the internal friction surface of the mold is inaccurate. And the arrival position is also uncertain, so it is easy to cause excessive heat generation of the mold and cause wire breakage, and the life of the mold is relatively short

At the same time, the existing wire drawing machine consumes a lot of drawing oil, and the metal powder produced during the drawing process will enter the drawing oil, resulting in many impurities in the drawing oil, which will affect the drawing quality of the mold, and the service life of the drawing oil is short. Difficult to deal with waste oil
