What effect does heat treatment have on the performance of progressive die for automotive new energy motor?

Improve mold hardness and wear resistance
Heat treatment can significantly improve the hardness and wear resistance of mold steel through quenching, tempering and other processes. This is especially important for progressive dies, because progressive die for automotive new energy motor needs to withstand large punching force and friction during use. If the die hardness is insufficient, wear and deformation will easily occur, thus affecting the accuracy of the die. and service life. Through heat treatment, the surface hardness and wear resistance of the mold are improved, which can better resist wear and deformation during the stamping process and ensure the long-term stability and accuracy of the mold.
Optimize mold organization structure
Heat treatment can change the microstructure of mold steel, such as refining the grains, changing the phase composition, etc. These changes help optimize the mold's performance, increasing its strength and toughness. For progressive dies, the optimized organizational structure means better fatigue resistance and longer service life. At the same time, refining the grains can also improve the corrosion resistance and oxidation resistance of the mold, further extending the service life of the mold.
Eliminate internal stress and improve stability
Zhejiang Ruixin Mold Technology Co., Ltd. has advanced manufacturing equipment and quality control equipment. It has rich manufacturing experience and technical strength in new energy motor core progressive molds, which can ensure high precision and high quality of molds. During the mold processing process, due to the influence of cutting, grinding and other processes, a certain amount of internal stress will be generated inside the mold. If these internal stresses are not eliminated in time, they will have a negative impact on the performance and service life of the mold. The annealing and tempering processes during heat treatment can effectively eliminate these internal stresses and improve the stability and accuracy of the mold. This is especially important for progressive dies, which need to maintain stable accuracy and performance during the continuous stamping process.
Adapt to different working environments
The working environment of new energy vehicle drive motors is often complex, including harsh conditions such as high temperature, high pressure, and high humidity. Through heat treatment, the properties of mold steel can be adjusted to better suit these working environments. For example, through the quenching and tempering process, the high-temperature strength and thermal stability of the mold can be improved so that it can maintain stable performance in high-temperature environments.
