Description

Technical Field

[0001] This utility model relates to the field of molding die technology, and more specifically, to a metal extrusion molding die. Background Technology

[0002] When steel wire is processed, it needs to be cold-drawn to change its radius. Generally, when steel wire is drawn, its radius is changed by passing it through a drawing die. The drawing die consists of an inlet area, a sizing area, and an outlet area. The radius of the steel wire changes when it passes through the sizing area.

[0003] A search revealed that utility model patent CN220781832U discloses a steel wire drawing die, including a base with several support seats fixedly connected to it. A first pressing die is detachably connected to one support seat at one end of the base, and a third pressing die is detachably connected to one support seat at the other end of the base. A second pressing die group is detachably connected to several support seats in the middle of the base. The second pressing die group includes several second pressing dies, each detachably connected to a corresponding support seat. The first, second, and third pressing dies each have frustum-shaped slots at both ends in the middle. After the steel wire is drawn through the first pressing die, it is then slowly and gradually drawn through several second pressing dies, which improves the quality and efficiency of steel wire drawing and reduces the breakage frequency of the steel wire during the drawing process. The third pressing die supports and transmits the drawn steel wire. However, the above patent still has the following shortcomings: Although the drawing die can be adjusted and replaced, multiple screws need to be turned when replacing it, and the required die needs to be found and matched each time, which is not convenient. In addition, the die generates heat when extruding the steel wire. If the heat is not dissipated in time, the die will deform and wear will be aggravated, which will affect the wire drawing effect and product quality. Therefore, we have proposed a metal extrusion forming die. Utility Model Content
