什么原因可能导致路沿石钢模具使用寿命减短
发布人:管理员   发布时间:2020-9-5

路沿石钢模具耐磨性:坯料在模具型腔中塑性变性时,沿型腔表面既流动又滑动,使型腔表面与坯料间产生剧烈的摩擦,从而导致模具因磨损而失效.所以材料的耐磨性是模具最基本、最重要的性能之一.硬度是影响耐性的主要因素.
Wear resistance of die for curbstone steel: when the blank is plastic denatured in the mold cavity, it flows and slides along the surface of the cavity, which causes severe friction between the surface of the cavity and the blank, resulting in the failure of the die due to wear. Therefore, the wear resistance of the material is one of the most basic and important properties of the mold. Hardness is the main factor affecting the durability

一般情况下,模具零件的硬度越高,磨损量越小,耐磨性也越好.另外,耐磨性还与材料中碳化物的种类、数量、形态、大小及分布有关.
Generally speaking, the higher the hardness of die parts is, the smaller the wear loss is, and the better the wear resistance is. In addition, the wear resistance is also related to the type, quantity, shape, size and distribution of carbides in the material

           

路沿石钢模具强韧性:模具的工作条件大多十分恶劣,有些常承受较大的冲击负荷,从而导致脆性断裂.为防止路沿石钢模具零件在工作时突然脆断,模具要具有较高的强度和韧性.模具的韧性主要取决于材料的含碳量、晶粒度及组织状态.
Strength and toughness of the die for curbstone steel: most of the working conditions of the die are very bad, and some of them often bear large impact load, which leads to brittle fracture. In order to prevent the parts of the stone steel mould from breaking suddenly, the die should have high strength and toughness. The toughness of the die mainly depends on the carbon content, grain size and microstructure of the material

路沿石钢模具疲劳断裂性能:模具工作过程中,在循环应力的长期作用下,往往导致疲劳断裂.其形式有小能量多次冲击疲劳断裂、拉伸疲劳断裂接触疲劳断裂及弯曲疲劳断裂.模具的疲劳断裂性能主要取决于其强度、韧性、硬度、以及材料中夹杂物的含量.
Fatigue fracture performance of die for curbstone steel: in the process of die working, under the long-term effect of cyclic stress, it often leads to fatigue fracture. Its forms include small energy multiple impact fatigue fracture, tensile fatigue fracture, contact fatigue fracture and bending fatigue fracture. The fatigue fracture performance of the die mainly depends on its strength, toughness, hardness and the content of inclusions in the material

这些特点都是我们平时使用路沿石钢模具设备中及其关注的重点问题,这与后期的使用成效直接挂钩,因此对于此方面的要求也是我们平时在选购中需要重点注意的.
These characteristics are our usual use of stone steel mold equipment and focus on the key issues, which are directly linked to the use of late results, so for this aspect of the requirements are usually we need to pay attention to in the purchase
