    模具钢材硬度的重要性是怎样的?

    来源:/ 日期:2022-09-14 发布人:admin


    在工业生产中,模具钢是模具工业的主体材料,那么  模具钢材硬度的重要性是怎样的?下面山东热作模具钢厂家为您解析。
    In industrial production, mold steel is the main material of the mold industry. What is the importance of the hardness of mold steel? Below, Shandong hot work die steel manufacturers will analyze for you.
    模具的使用寿命和制成零件的精度、质量、外观性能,除与模具的设计技术、制造精度,以及机床精度和制造操作有关外,正确地选用模具材料和正确的执行热处理质量和使用性能通常都以硬度作为判断的依据。
    The service life of the mold and the accuracy, quality and appearance performance of the parts made are related to mold design technology, manufacturing accuracy, machine tool accuracy and manufacturing operation. In addition, the hardness is usually used as the basis for determining the quality and performance of the mold materials and heat treatment correctly.
    硬度是模具材料和成品模具的重要性能指标。模具在工作时的受力状态是复杂的,如热作模具通常是在交变的温度场下承受交变应力作用,因此它应具有良好的阻止模具转变成较软或塑性状态的能力,并且在长期工作环境下仍保持模具的形状和尺寸精度不变。一般成品模具的硬度,冷作模具常选择在59-60HRC,热作模具常选择在48HRC左右。
    Hardness is an important performance index of mold materials and finished molds. The stress state of the mold during working is complex. For example, the hot working mold usually bears the alternating stress under the alternating temperature field, so it should have a good ability to prevent the mold from changing into a soft or plastic state, and still maintain the shape and dimensional accuracy of the mold under a long-term working environment. Generally, the hardness of finished molds is 59-60HRC for cold working molds and 48HRC for hot working molds.

    耐磨性也是成品模具的重要性能指标。零件成型时金属和模具型腔表面发生相对运动,磨损了型腔表面,致使模具的尺寸形状、精度和表面粗糙度发生变化而失效。模具的耐磨性是由模具的热处理,特别是表面热处理决定的,评估模具耐磨性好坏的主要依据也是硬度。
    Wear resistance is also an important performance index of the finished mold. The relative movement between the metal and the surface of the mold cavity during the forming of the part has worn the surface of the mold cavity, resulting in the change of the size, shape, accuracy and surface roughness of the mold and failure. The wear resistance of the mold is determined by the heat treatment of the mold, especially the surface heat treatment. The main basis for evaluating the wear resistance of the mold is also the hardness.
    此外大家应该都知道,钢是由铁冶炼成的,而铁一但与空气的水跟氧气接触就会产生化学反应,形成三氧化二铁,也就是棕红色的锈迹,所以各位在存放钢材的时候尽量避免潮湿的地方,也可以喷点防锈油来防止材料生锈。
    In addition, we should all know that steel is made from iron smelting, and once iron contacts with air, water and oxygen, it will produce chemical reaction, forming ferric oxide, that is, brownish red rust. Therefore, when you store steel, you should try to avoid wet places, and you can also spray some antirust oil to prevent materials from rusting.
    那如果所产模具需要带有防锈,防腐性能,应该选择哪些材料呢,我们建议选择是含Cr,含Ni成分比较高的材料,比如像S136模具钢,2083模具钢,2316模具钢等,这些材料含Cr量都达到了12.5%甚更多,具有很好的防锈功能。
    If the molds produced need to have anti rust and anti-corrosion properties, which materials should be selected? We suggest to select materials containing Cr and high Ni content, such as S136 mold steel, 2083 mold steel, 2316 mold steel, etc. These materials have a Cr content of 12.5% or more, which has a good anti rust function.
    所以在选择材质以及材料的存放地点时,都要注意其是否具有防锈性能,避免材料生锈影响模具的使用与美观。更多相关内容就来我们网站进行咨询吧!
    Therefore, when selecting materials and storage locations of materials, we should pay attention to whether they have anti rust performance to avoid the impact of material rust on the use and beauty of the mold. More relevant content will come to our website Consult!
