Few.
6) mold notch material is changed to SKH51, and SKH-51 is for tungstenic high-speed tool steel, and its characteristic is：1st, high-wearing feature,
2nd, high compressive strength, 3, harden after high case hardness, 4, excellent overall quenching degree, 5, good surface treatment processability,
6th, excellent anti-temper softening, thus ensure that lower mould enters the edges of a knife such as block and is not easily broken.
7) take off material and nitrogen spring is replaced by by excellent power glue, de- material power uniformly, seldom occurs not take off material, get stuck phenomenon.
8) outline of the outline of boring cover molding concave die and die fixed seat adopts the structure of dodecagon it is ensured that tying
The stability of structure and stress uniform.
9) leave the distance of a boring cover molding between boring cover material profile drift and boring cover forming punching head, advantageously ensure that
The planarization of feeding before boring cover molding.
