    银河国际·Galaxy材具有足够的淬硬层

    来源:/ 日期:2022-04-12 发布人:admin


    银河国际·Galaxy材钢实践上是指模具零件的热处理。冷加工模具有很多种,首要包含冷冲裁模、冷镦模、冷挤压模、冷拉深拉模等。于形状和结构的巨大差异,作业条件和功能要求也不同。除了挑选台适的资料外,还应挑选Z佳的热处理工艺,以满意模具的使用功能要求,并进步模具的使用寿命。
    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.
    冷加工模具需要在锻后进行球化退火,清理锻坯的铸造应力,改进显微安排,下降硬度,以便于机械加工,为Z终热处理做准备。
    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.
    淬火是冷加工模具终热处理中的一项重要操作。它对模具的使用功能有很大的影响,应特别注意。应注意以下几点:
    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)应承认模具资料,并查看模具表面是否有划痕和裂纹等缺点。
    1) Acknowledge the mold data and check whether there are scratches, cracks and other defects on the mold surface.
    2)根据模具的形状,估计模具的文学和武术的趋势,并使各种各样的堵塞,绑定或绑定,以使均匀的加热和冷却。
    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)淬火加热温度的合理挑选奥氏体不只需要与某些合远素和碳固溶,以保证模具的淬透性、硬化才能、强度和热硬度,并且需要有恰当的过量碳化物来细化晶粒,进步模具的耐磨性,并保证模具具有必定的耐性。同时,应考虑模具温度对加热过程中变形和预热的影响。
    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、加热和保温时刻的合理挑选对于-般模具的淬火和加热,保温时刻可根据加热设备选用的经历公式计算。然而,在实践热处理操作中,应考虑模具零件的具体条件。特别是对于复杂的模具,应综合考虑各种影响因素,经过试验确认淬火和保温时刻。
    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.
