水沟盖板模具疲劳断裂性能:模盒工作过程中,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。模盒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 property of the ditch cover mould: fatigue failure is often caused by the long-term effect of cyclic stress during the operation of the mould box. Its form is small energy, multiple impact fatigue fracture, tensile fatigue fracture, contact fatigue fracture and bending fatigue fracture. The fatigue fracture properties of the mould box mainly depend on its strength, toughness, hardness, and the content of inclusions in the material.
水沟盖板模具高温性能:当模盒的工作温度较高进,会使硬度和强度下降,导致模盒早期磨损或产生塑性变形而失效。因此,模盒材料应盒有较高的抗回火稳定性,以保证模盒在工作温度下,盒有较高的硬度和强度。
The high temperature performance of the groove cover die: when the working temperature of the mold box is higher, the hardness and strength will decrease, resulting in the failure of the early wear or plastic deformation of the mold box. Therefore, the box material should have higher resistance to tempering, so that the mold box has higher hardness and strength at the working temperature.
