            模具鋼材硬度的重要性是怎樣的?

            在工業生產中,模具鋼是模具工業的主體材料,那么  模具鋼材硬度的重要性是怎樣的?下面山東熱作模具鋼廠家為您解析。
            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.
            模具的使用壽命和制成零件的精度、質量、外觀性能,除與模具的設計技術、制造精度,以及機床精度和制造操作有關外,正確地選用模具材料和正確的執行熱處理質量和使用性能通常都以硬度作為判斷的依據。
            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標。模具在工作時的受力狀態是復雜的,如熱作模具通常是在交變的溫度場下承受交變應力作用,因此它應具有良好的阻止模具轉變成較軟或塑性狀態的能力,并且在長期工作環境下仍保持模具的形狀和尺寸精度不變。一般成品模具的硬度,冷作模具常選擇在59-60HRC,熱作模具常選擇在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標。零件成型時金屬和模具型腔表面發生相對運動,磨損了型腔表面,致使模具的尺寸形狀、精度和表面粗糙度發生變化而失效。模具的耐磨性是由模具的熱處理,特別是表面熱處理決定的,評估模具耐磨性好壞的主要依據也是硬度。
            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.
            此外大家應該都知道,鋼是由鐵冶煉成的,而鐵一但與空氣的水跟氧氣接觸就會產生化學反應,形成三氧化二鐵,也就是棕紅色的銹跡,所以各位在存放鋼材的時候盡量避免潮濕的地方,也可以噴點防銹油來防止材料生銹。
            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.
            那如果所產模具需要帶有防銹,防腐性能,應該選擇哪些材料呢,我們建議選擇是含Cr,含Ni成分比較高的材料,比如像S136模具鋼,2083模具鋼,2316模具鋼等,這些材料含Cr量都達到了12.5%甚至更多,具有很好的防銹功能。
            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.
            所以在選擇材質以及材料的存放地點時,都要注意其是否具有防銹性能,避免材料生銹影響模具的使用與美觀。更多相關內容就來我們網站http://www.environmentandpeople.net進行咨詢吧!
            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.
