In the process of wire drawing, the quality of the wire drawing die directly affects the wire production tribute, output, die consumption and energy consumption. In order to prolong the service life of the wire drawing die and reduce the use cost of the wire drawing die, the production technology department of our factory has organized technicians to design and improve the structure and tree quality of the traditional wire drawing die several times since 1998. Through the operation, structure, price, and service life Comparing with other aspects, finally selected the taper direct water-cooled wire drawing die as our factory's shaping wire drawing die to promote and use, after more than one year of use, it has reached the design requirements. This article introduces the structural features and use effects of the taper direct water-cooled wire drawing die.

     The material and structure of the conical direct cold die is the same as the traditional wire drawing die. The die sleeve is made of 45 steel, and the die core is hard alloy. The grade is YG3 or YG3X. The population cone, lubrication cone, working cone, and outlet cone of the die hole are the same as the traditional drawing die. In terms of structure, the core and the sleeve of the tapered straight cold mold are matched with a taper of 1:15. The inner wall of the mold sleeve is provided with a water cooling groove and a water cooling hole is drilled outside the groove.
