Stamping die

　　The service life, processing precision and stable performance of Stamping die depend on the scientific selection and quality control of materials. As the core supporting component of the sheet metal stamping process, the stamping die must bear the impact force and friction force of high-frequency stamping, and adapt to the stamping needs of different materials and specifications. Therefore, the material selection strictly follows the core principles of "high strength, high wear resistance, high toughness and strong adaptability", accurately matching the functional needs of different mold components such as punches, dies, mold bases and guide parts. It solves the industry pain points such as easy wear, easy cracking and rapid precision attenuation of the mold, provides solid guarantee for efficient and precise sheet metal stamping production, extends the service life of the mold and reduces production costs.

　　Core Material 1: Mold Steel (Model Cr12MoV, SKD11), the preferred material for the core force-bearing components of stamping dies. Cr12MoV mold steel has extremely high hardness, wear resistance and hardenability. After heat treatment processes such as quenching and tempering, the hardness can reach HRC60-62, which can bear the impact force and friction force of high-frequency stamping, not easy to wear or deform. It is suitable for harsh scenarios such as medium and thick plate stamping and high-strength plate stamping, and is mainly used to manufacture core force-bearing components such as punches and dies, ensuring that the mold can still maintain precise dimensional accuracy after long-term use, and extending the service life of the mold to more than 100,000 times.

　　Core Material 2: High-Speed Steel (W6Mo5Cr4V2), focusing on the needs of high-precision and high-speed stamping scenarios. This material has excellent red hardness and wear resistance, and can still maintain good hardness and toughness in high-temperature environments, not easy to appear thermal fatigue, cracking and other problems. It is suitable for high-speed stamping and precision small part stamping scenarios, and can be used to manufacture precision components such as mold cutting edges and small punches. It can accurately complete the stamping processing of complex shapes and high precision, and has good processing performance, which can be flexibly processed and formed according to the mold design needs, ensuring the dimensional consistency of stamping parts.

　　Core Material 3: Cast Iron (HT200, QT500), focusing on the materials for load-bearing components such as mold bases and bases. HT200 gray cast iron has good rigidity, shock absorption and cost performance, with a flat surface and low processing difficulty. It can be used to manufacture non-core force-bearing components such as mold bases and bases, which can stably support the overall structure of the mold, absorb the impact force during stamping, reduce mold vibration and ensure the stability of the stamping process; QT500 ductile iron has upgraded performance on the basis of gray cast iron, with greatly improved toughness and strength, suitable for the manufacture of mold bases for large stamping dies, which can bear greater weight and impact force, avoiding mold base deformation and fracture.

　　Auxiliary Materials: Copper alloy, graphite, etc., to improve mold adaptability and service life. Copper alloy has good thermal conductivity and wear resistance, which is used to manufacture mold guide parts, ejector pins and other components, reducing friction between components, improving the smoothness of mold operation and avoiding jamming; graphite, as a lubricating material, can be applied to the mold cutting edge and cavity surface, reducing friction between the sheet and the mold during stamping, preventing sheet scratches, and reducing mold wear, further extending the service life of the mold, taking into account processing precision and product appearance quality.
