            冷作模具鋼材具有足夠的淬硬層

            冷作模具鋼材鋼實踐上是指模具零件的熱處理。冷加工模具有很多種,首要包含冷沖裁模、冷鐓模、冷擠壓模、冷拉深拉模等。于形狀和結構的巨大差異,作業條件和功能要求也不同。除了挑選臺適的資料外,還應挑選Z佳的熱處理工藝,以滿意模具的使用功能要求,并進步模具的使用壽命。
            In practice, cold work die steel refers to the heat treatment of die parts. There are many kinds of cold working dies, mainly including cold blanking die, cold heading die, cold extrusion die, cold drawing die, etc. Due to the great differences in shape and structure, the operating conditions and functional requirements are also different. In addition to selecting suitable materials, we should also select z-best heat treatment process to meet the functional requirements of the die and improve the service life of the die.
            冷加工模具需要在鍛后進行球化退火,清理鍛坯的鑄造應力,改進顯微安排,下降硬度,以便于機械加工,為Z終熱處理做準備。
            The cold working die needs spheroidizing annealing after forging, cleaning the casting stress of the forging blank, improving the microstructure arrangement and reducing the hardness, so as to facilitate machining and prepare for Z final heat treatment.
            淬火是冷加工模具終熱處理中的一項重要操作。它對模具的使用功能有很大的影響,應特別注意。應注意以下幾點:
            Quenching is an important operation in the final heat treatment of cold working die. It has a great impact on the use function of the die, which should be paid special attention to. The following points should be noted:
            1)應承認模具資料,并查看模具表面是否有劃痕和裂紋等缺點。
            1) Acknowledge the mold data and check whether there are scratches, cracks and other defects on the mold surface.
            2)根據模具的形狀,估計模具的文學和武術的趨勢,并使各種各樣的堵塞,綁定或綁定,以使均勻的加熱和冷卻。
            2) According to the shape of the mold, estimate the trend of mold literature and martial arts, and make a variety of blocking, binding or binding to make uniform heating and cooling.
            3)淬火加熱溫度的合理挑選奧氏體不只需要與某些合遠素和碳固溶,以保證模具的淬透性、硬化才能、強度和熱硬度,并且需要有恰當的過量碳化物來細化晶粒,進步模具的耐磨性,并保證模具具有必定的耐性。同時,應考慮模具溫度對加熱過程中變形和預熱的影響。
            3) Reasonable selection of quenching heating temperature austenite not only needs solid solution with some alloying elements and carbon to ensure the hardenability, hardening ability, strength and thermal hardness of the die, but also needs appropriate excess carbide to refine the grain, improve the wear resistance of the die and ensure that the die has certain resistance. At the same time, the influence of mold temperature on deformation and preheating during heating should be considered.
            4)淬火、加熱和保溫時刻的合理挑選對于-般模具的淬火和加熱,保溫時刻可根據加熱設備選用的經歷公式計算。然而,在實踐熱處理操作中,應考慮模具零件的具體條件。特別是對于復雜的模具,應綜合考慮各種影響因素,經過試驗確認淬火和保溫時刻。
            4) Reasonable selection of quenching, heating and heat preservation time for the quenching and heating of general molds, the heat preservation time can be calculated according to the experience formula selected by the heating equipment. However, the specific conditions of die parts should be considered in the practical heat treatment operation. Especially for complex molds, various influencing factors should be comprehensively considered, and the quenching and holding time should be confirmed through tests.
