Die is an important part of metal stamping processing. The quality of metal stamping is basically determined by the quality of stamping die. To ensure the quality of metal stamping die


With life and precision, it is necessary to understand the hot processing technology and precautions of metal stamping die.

In order to eliminate grinding residual stress, stamping die should be treated at low temperature after grinding to improve toughness. This process is an important part in the production of die parts.


In the links, it is necessary to strictly control the forging temperature scale, draw up accurate heating scale, select accurate forging force method, and slow cooling or timely annealing after forging. Die quenching heating


Special attention should be paid to avoiding oxidation and decarbonization. The heat treatment process scale should be strictly controlled. Due to quenching stress and network carbide structure, phase transformation occurs under the action of grinding force.


It is very easy to crack the workpiece. This step is an important step in the heat treatment of dies and moulds. There are more differences in materials and requirements of die parts to choose annealing, normalizing or tempering.


Prepare heat treatment process, eliminate the shortcomings of forging blank, improve the processing technology of metal stamping parts.

In addition, the following points need to be noted:

1. Preparatory heat treatment;

2. Forging technology. ;

3. Quenching and tempering;

4. Stress relief annealing. This process has limited or insignificant effect on general low carbon steel plate, but it is very useful for stainless steel. Detailed annealing process
