Stamping mould processing

Stamping mould processing The working parts of the material requirements

    Stamping die Work to withstand shock, vibration, friction, pressure and tension, bending and torsion load, and even work at higher temperatures (such as cold extrusion), complex working conditions, easy abrasion, fatigue, fracture and deformation phenomenon. Therefore, the mold work parts material requirements than ordinary high parts.

Because of all kinds of stamping die working conditions are different, so the die parts of the material requirements are also different.

Blanking die material requirements for sheet metal stamping die working parts material requirements having abrasion resistance and high hardness, and blanking die plate with compressive resistance, in addition to the requirements of high yield point, in order to prevent mould breaking or chipping, should also have the flexural strength and toughness, high fracture resistance the high.

Drawing die material requirements, requirements of die parts material has good anti adhesion (anti bite), toughness, wear resistance and hardness of the high cutting and good processing performance, and heat treatment to small deformation.

Cold extrusion die material requirements, requirements of die parts have high strength and hardness, high wear resistance, broken in order to avoid the impact, also requires a certain toughness. Because the extrusion will produce large temperature, so we should also have a certain heat fatigue and hot hardness
