Brief Introduction

Pully type wire drawing machine also named bull block wire drawing machine. It is the most popular machine for wire drawing in China at present. With the development of more automatic type wire drawing machine, pully type wire drawing machine also has improved much. And with its absolutely advantages, it will never be totally insteaded by the various other types of wire drawing machine.

The working principle of the bull black wire drawing machine mainly depends on its unique composition structure and operation mode. The bull block wire drawing machine is composed of a main reduction box, a mold box, a wheel frame, a wire drawing frame and an electrical control system. Each wire drawing reel is driven by a motor through a gear coupling to reduce the speed of two-stage cylindrical gears with different speed ratios, so that the reel rotates and works. The wire drawing reel is vertical and installed on the cover of the box. The gear pair is lubricated with oil immersion. The inner wall of the reel is equipped with a cooling water spray device to reduce the residual heat on the surface of the wire conveyor reel after drawing. The drawing die is immersed in cooling water to reduce the working temperature of the die. This design helps to keep the surface wear of the wire and the reel relatively small during the drawing process, and at the same time ensures that when a certain reel in the middle stops temporarily, the reels behind it can still work normally for a period of time based on their respective accumulated wire volume.
