The cutting die steel is a special die cutting rule with single (double) side edge and thickened type for manufacturing cutting dies with complex shapes. As a key part of light industrial machinery (a blanking machine or a punching and shearing machine), the die steel is widely applied to blanking and forming of products such as textiles, leather, plastics and the like, and relates to the field of light industrial products such as shoes, cases, clothes, automotive interiors, furniture, toys and the like. The cutter die for manufacturing the special-shaped complex shape and realizing large-size blanking by using the cutter die steel needs to have both high strength and bending property. The production process flow of the die steel comprises the following steps: continuous acid washing, longitudinal shearing and splitting, cold rolling, quenching and tempering of a cutter body, broaching, cutting edge grinding and quenching hardening, splitting and automatic stacking.

Rolling: the steel strip after splitting and coiling is rolled flat and substantially shaped by a rolling mill.

And (4) limiting and controlling the cutting allowance of the rolling of the cutting die steel, and automatically grinding the cutter. The adoption of the white steel knife changes the original manual knife sharpening into the automatic knife sharpening of the knife sharpener, and the omnibearing limit structure improves the stability, and the rigidity of the designed knife rest structure is improved, thereby reducing the maintenance. The thickness of the steel cutter body of the cutting die is uniformly controlled, and the deviation and the inconsistency of the sizing size when the cutting die is formed are avoided.
