What are the processing quality factors of the wire drawing die that cause the rapid wear of the die?
1. The drawing die blank and the mold steel sleeve are asymmetrically inlaid, and the inlaid carbide steel sleeve is unevenly distributed and has gaps, which are likely to cause U-shaped cracks in the drawing process of the wire.
2. In the process of laser drilling, the sintering marks are not cleaned or the force is not uniform, which will cause the dents of the diamond during the drawing process.
3. The mold hole design is unreasonable, the opening of the inlet lubrication area is too small, and the sizing belt is too long, which will lead to poor lubrication during the drawing process, resulting in accelerated mold wear and even chipping.
