Description

TECHNICAL FIELD

[0001] The utility model relates to wire rod processing technical field, concretely relates to a wire rod down -pressing structure. BACKGROUND

[0002] Before the metal wire such as stainless steel wire is drawn, it needs to be phosphorized first. Because the traditional wire rod is thick and the drawing speed is slow, the commonly used phosphorizing method is to use a phosphorizing tank, heat the phosphorizing liquid in the tank to above 80 DEG C, and the metal wire slowly passes through the phosphorizing liquid, and a phosphorizing film is formed on the surface of the metal wire after a certain time of reaction. But because this phosphorizing method is not suitable for small diameter wire rod and high speed drawing, the thick phosphorizing film will gather in the drawing die and cause die jamming, and the low phosphorizing speed also cannot be integrated into the high speed drawing process line, so it is not suitable for high speed fine wire drawing.

[0003] With the emergence of high speed drawing process, the wire rod is wound on the phosphorizing wheel, the lower half of the phosphorizing wheel is in contact with the phosphorizing liquid, so that the wire rod reciprocatingly reacts with the phosphorizing liquid when moving in the circumferential direction, and the reaction time is short and sufficient. At present, two phosphorizing wheels are usually arranged, and the wire rod is wound on the two phosphorizing wheels in turn. Because there is a certain distance between the two phosphorizing wheels, the wire rod may be loose after winding for many times, and the loose wire rod not only shakes to affect the phosphorizing reaction, but also causes the phosphorizing liquid to splash.
