How do we guarantee the length of the stamping die when we process the stamping die parts? First of all, we only have a deep understanding of stamping dies to solve the problems we face. Summer heat can't stop our enthusiasm for learning new knowledge. Today, together with Yize Mould, we can understand some factors that determine the length of life of stamping die.

First, stamping equipment

The accuracy of the stamping equipment and the impact of the rigid stamping die life are extremely important. The precision of the stamping equipment is high, the rigidity is good, and the die life is greatly improved. Precision dies must be selected with high precision and good rigidity. Otherwise, the life of the mold will be reduced and the mold will be damaged seriously.

Second, the mold design

1. Precision of the guiding mechanism of the mold: In order to improve the life of the mold, it is necessary to correctly select the guiding form and determine the accuracy of the guiding mechanism according to the requirements of the nature of the process and the accuracy of the parts.

2. Geometric parameters of the die edge: the shape of the convex and concave die, the fit clearance and the fillet radius not only have a great influence on the forming of the stamping part, but also have a great influence on the wear and life of the die. If the accuracy is high, the smaller gap value should be selected. Otherwise, the gap can be increased to improve the die life.

Third, the stamping process

1. Raw materials for stamping parts

2. Layout and edge

Fourth, the mold material

The influence of mold materials on mold life is a comprehensive reflection of material type, chemical composition, microstructure, hardness and metallurgical quality. The life of molds of different materials is often different.

Five, thermal processing technology

1. Forging process: This is an important part in the manufacturing process of mold parts. The forging temperature range should be strictly controlled during processing, the correct heating specification should be established, the correct forging method should be adopted, and the slow cooling or timely annealing after forging should be carried out.

2. Pre-heat treatment: Pre-heat treatment processes such as annealing, normalizing or quenching and tempering should be used according to the materials and requirements of the mold parts to improve the processing technology.

3. Quenching and tempering: This is the key link in the heat treatment of the mold. During the quenching and heating of the die, special attention should be paid to preventing oxidation and decarburization. The heat treatment process specification should be strictly controlled. If conditions permit, vacuum heat treatment can be used.

4. Stress relief annealing: For molds with high precision requirements, after flat grinding, grinding or electric machining, it needs to be subjected to stress relief and tempering treatment, which is beneficial to stabilize mold precision and improve service life.

Sixth, processing surface quality

The advantages of mold workpiece parts and surface quality have a close relationship with the wear resistance, fracture resistance and anti-adhesion ability of the mold, which directly affects the service life of the mold.
