            模具鋼是用來制造冷沖模、熱鍛模壓鑄模等模具的鋼種。模具是機械制造、無線電儀表、電機電器等工業部門中制造零件的主要加工工具。
            Die steel is used to make cold stamping die, hot forging die, die casting die and so on. Mold is the main processing tool for manufacturing parts in mechanical manufacturing, radio instruments, electrical machinery and other industrial sectors.
            模具的質量直接影響著壓力加工工藝的質量、產品的精度產量和生產成本、而模具的質量與使用壽命除了靠合理的結構設計和加工精度外,主要受模具材料和熱處理的影響。
            The quality of the mold directly affects the quality of the pressure processing technology, the precision of the product, the output and the production cost. The quality and service life of the mold are mainly affected by the mold material and heat treatment besides the reasonable structure design and processing precision.
            當今高強鋼、強鋼很好的實現了車輛的輕量化,提高了車輛的碰撞強度和安全性能 ***模具鋼h13,因此成為車用鋼材的重要發展方向。
            Nowadays, high strength steel and high strength steel realize the lightweight of vehicle and improve the impact strength and safety performance of vehicle. Die steel H13 has become an important development direction of vehicle steel.
            但隨著板料強度的提高,傳統的冷沖壓工藝在成型過程中容易產生破裂現象,無法滿足高強度鋼板的加工工藝要求。在無法滿足成型條件的情況下,國際上逐漸研究強度鋼板的熱沖壓成形技術。
            However, with the improvement of sheet metal strength, the traditional cold stamping process is prone to fracture in the forming process, which can not meet the processing requirements of high strength steel plate. In the case of unable to meet the forming conditions, the hot stamping technology of high strength steel plate is gradually studied in the world.
            該技術是綜合了成形、傳熱以及組織相變的一種新工藝,主要是利用高溫奧氏體狀態下 熱作模具鋼,板料的塑性增加,屈服強度降低的特點 加工模具鋼產品,通過模具進行成形的工藝。但是熱成型需要對工藝條件、金屬相變、cae分析技術進行深入研究,該技術被國外廠商壟斷,--發展緩慢。
            This technology is a new process which integrates forming, heat transfer and microstructure transformation. It is mainly a process which makes use of the characteristics of hot working die steel in high temperature austenite state, that is, the plasticity of sheet increases and the yield strength decreases, to process die steel products, and to form through the die. However, hot forming needs to study the process conditions, metal phase transformation and CAE analysis technology, which is monopolized by foreign manufacturers and develops slowly.
