In the process of processing thick wire or steel wire into fine wire or steel wire, drawing die is an important part and plays a very important role. When using the wire drawing machine, the wire or steel wire or even steel bar will become cold drawn steel wire with smaller diameter than the original wire or steel bar after passing through the wire drawing die, and the wire drawing die is usually worn after repeated use. In order to prolong the service life of the wire drawing die, we analyze the reasons for the rapid damage of the wire drawing die, and avoid these reasons can effectively prolong the service life of the wire drawing die. Let's see.

1. In the process of wire drawing, the inlay of die blank and die steel sleeve is asymmetric, and the inlaid carbide steel sleeve is unevenly distributed or has a large gap, which easily leads to U-shaped cracks in the process of wire drawing;

2. In the process of laser drilling, if the sintering trace is not clean or the heating is not uniform, the metal catalyst and adhesive in the diamond layer will gather together, and it is easy to form pits in the die during the drawing process

3. Unreasonable pass design, too small opening of inlet lubrication zone and too long solidification zone will lead to poor lubrication, die wear and even fragmentation.

Finding out these reasons and putting forward the necessary solutions can effectively prolong the service life of the drawing die, reduce the production cost and improve the work efficiency.
