Abstract
A wire drawing die relates to metal material processing dies and comprises a die body. The die body is provided with a die hole, and a tungsten carbide coating layer is coated on the inner wall of the die hole. An inlet area, a lubricating area and a compressing area which are all taper-shaped are respectively arranged at an inlet end of the die hole and in circular-arc connection sequentially, and taper angles of the inlet area, the lubricating area and the compressing area are reduced sequentially. A pressure releasing area and an air outlet area which are taper-shaped are respectively arranged at an outlet end of the die hole and are in circular-arc connection sequentially, and taper angles of the pressure releasing area and the outlet area are increased sequentially. A cylindrical sizing area is formed between the compressing area and the pressure releasing area of the die hole, and is in circular-arc connection with the compressing area and the pressure releasing area sequentially. Since the die hole is divided into multiple angles and multiple work areas, abrasion to the die is reduced during wire drawing, while the wire drawing die has the advantages of high precision and stability and can be applicable to production of wires at the levels of 0.1mm and 0.01mm.
