Stamping parts manufacturers use material characteristics and cold work hardening-hardware

Stamping materials have higher requirements for metallographic structure. The same material has different heat treatments, and its metallographic structure and elongation are also different, which also has a significant impact on the quality of stamping parts. Stamping parts manufacturers, first of all, understand the characteristics of various metal materials, so as to serve every customer well. For example, for carbon steels and alloy steels with a carbon content of more than 0.35%, the shape and distribution of cementite (Fe3C) have a decisive effect on the shear surface finish. Among them, spheroidizing (after spheroidizing annealing) is carbonized The fine-grained uniform distribution is ideal, and it is difficult to punch out a smooth shearing surface with a piece of pearlite tissue. It is a carbon steel with a carbon content of 0.45%. Due to the difference in metallographic structure, different shear surface qualities can be obtained. On the left is the untreated ferrite-pearlite structure, and on the right is the spherical cementite after spheroidization. Cold work hardening in stamping Since stamping is a composite of extrusion-shearing processes, the crystal structure of the material in the shear zone produces strong cold work deformation. The outstanding performance is that the hardness of the material in the cold work hardening zone is significantly greater than the hardness of the matrix. For this reason, it is very necessary to grasp the deformation law of stamping cold work hardening, determine the size, shape and depth of cold work hardening, and the actual effect on fine blanking parts.
