Description

Technical Field

[0001] The utility model relates to the technical field of chain drawing equipment, in particular to a chain drawing equipment with improved strength performance. Background Technique

[0002] The production of elevator balance chains requires production processes such as wire drawing, knitting, and butt welding. Among them, wire drawing is to use a wire drawing machine to draw steel. The core structure of the wire drawing machine is a wire drawing die, whose main function is to force the steel through the die hole, compress its cross-sectional area, and process the steel into the required specifications and shapes of elevator balance chains. In the prior art, most of them cool the steel after wire drawing. However, when the steel deforms inside the wire drawing die, the heat generated by friction easily damages the internal metal structure of the steel, affecting the strength of the steel after wire drawing, and thus affecting the final use strength of the elevator balance chain.

[0003] When the existing chain drawing equipment with improved strength performance is actually used, it is not easy to cool the steel during the deformation process inside the wire drawing die, which has certain limitations.

[0004] After retrieval of existing patents: A wire drawing device for raw materials in the production of elevator balance chains (publication number: CN212703705U), its structure includes a wire drawing die. The wire drawing die includes an inlet end for steel wire drawing, a pressure die cavity for steel wire drawing, and an outlet end for steel wire drawing. The inlet end, the pressure die cavity, and the outlet end are arranged in sequence along the transmission direction of the steel wire drawing. The pressure die cavity is oblate, and a number of arc-shaped grooves are formed on the upper and lower circular surfaces of the pressure die cavity. The arc-shaped grooves are arranged along the transmission direction of the steel wire drawing, and cold air holes are provided inside the arc-shaped grooves. The cold air holes are communicated with cold air pipes. The utility model effectively protects the internal metal structure of the steel and improves the use strength of the elevator balance chain after production.

[0005] Although the above patent cools the steel through cold air holes, to a certain extent, it protects the internal metal structure of the steel and improves the use strength of the elevator balance chain after production, but the effect is not obvious. At the same time, it is not easy to lubricate the steel during the wire drawing process, which has certain limitations.

[0006] Therefore, it is very necessary to invent a chain drawing equipment with improved strength performance to solve the above problems. Utility Model Content
