Production and Application of Domestic Hexagonal Trimming Die

At present, the domestic production of hexagonal trimming die, especially large size (M12 above) stainless steel bolts with the mold, compared with foreign countries, its service life is generally low, so most of the domestic standard parts for the mold is still dependent on imports. Hexagonal trimming die in the cold heading hexagonal bolt forming process from the trimming and shaping role in the standard parts industry is very large.

Through the die force analysis, material optimization and other measures, significantly improve the M16 hexagonal trimming die life. With LD, GM and W6Mo5Cr4V2CoS steel production of M16 carbon steel and stainless steel bolts with the mold, the service life were SKH51, SKH55 steel manufacturing similar to the same level of imported mold, while the price was significantly reduced.
