How to repair drawing die regularly

In the long-term use of the wire drawing die, the die surface is subjected to strong friction and erosion of the metal wire, which inevitably produces wear. The most common is the appearance of annular grooves (dents) at the entrance of the wire in the work area. The appearance of the ring groove of the wire drawing die aggravates the wear of the die hole, because the small particles of the core material peeled off due to loosening on the ring groove are brought into the working area and sizing area of the die hole by the metal wire, which acts as an abrasive and enters The wire of the die hole exacerbates the wear of the die hole like a grinding pin. If the repair is not carried out in time, the ring groove will continue to accelerate and expand, making the repair more difficult. There may even be cracks in the deeper part of the ring groove, causing the dies to completely be scrapped.

We know from experience that it is very economical and cost-effective to work out a set of norms and standards, strengthen dally maintenance, and often perform maintenance on the drawing dies. Once there is any slight wear on the dies, polish it in time, it will take less time to restore the dies to the original polished state, and there is no obvious change in the die hole size.
