冷模鋼實(shí)際上是指模具零件的熱處理。冷沖裁模、冷扎模、冷擠壓模、冷拉深拉模等冷拉模具種類(lèi)繁多。在形狀結(jié)構(gòu)的巨大差異下，操作條件和功能規(guī)定也有所不同。除選擇合適的數(shù)據(jù)外，還應(yīng)選擇Z佳的熱處理方法，以適應(yīng)模具的使用，提高磨具的使用壽命。
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.
球化退火冷加工模具煅燒后，充分準(zhǔn)備Z終熱處理，清除鍛坯的鑄造應(yīng)力，改善顯微布局，降低強(qiáng)度，便于加工。
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的主要操作。應(yīng)注意模具的使用。應(yīng)注意以下幾點(diǎn)：
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(yīng)識(shí)別磨具數(shù)據(jù)，并檢查磨具表面是否有劃痕和裂紋。
1) Acknowledge the mold data and check whether there are scratches, cracks and other defects on the mold surface.
2)根據(jù)模具外觀(guān)，模具文學(xué)和武術(shù)的趨勢(shì)可能會(huì)導(dǎo)致各種阻塞、相關(guān)或綁定，以便均勻地加熱和制冷。
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）合理選擇淬火加熱溫度的馬氏體，不僅需要與一些合遠(yuǎn)素和碳固溶，還需要過(guò)多的滲碳體來(lái)細(xì)化晶粒，以保證模具的淬火、硬化水平和強(qiáng)度，提高模具的耐磨性，確保磨具有一定的耐久性。同時(shí)，應(yīng)注意磨具溫度對(duì)加熱環(huán)節(jié)變形和加熱的影響。
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)合理選擇淬火、加熱和保溫時(shí)間-磨具淬火和加熱，根據(jù)加熱設(shè)備選擇的經(jīng)驗(yàn)公式換算保溫時(shí)間。但在具體的熱處理操作中，應(yīng)注意模具零件的實(shí)際情況。但在具體的熱處理操作中，應(yīng)注意模具零件的實(shí)際情況。但在具體的熱處理操作中，應(yīng)注意模具零件的實(shí)際情況。特別是對(duì)于復(fù)雜的磨具，應(yīng)充分考慮各種相關(guān)因素，并確認(rèn)淬火和絕緣時(shí)間。
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.
