不锈钢九州体育 表面划痕形成的原因

网址:70707882@qq.com  2019-07-20  作者:admin    阅读:

不锈钢九州体育 表面出现划痕主要是由于工件和模具表面存在相对移动,在一定压力的作用下,致使坯料与模具局部表面直接产生摩擦,加之坯料的变形热使坯料及金属屑熔敷在模具表面上,使工件表面擦伤产生划痕。
The scratches on the surface of stainless steel stamping parts are mainly due to the relative movement of the workpiece and the die surface. Under certain pressure, the friction between the blank and the local surface of the die directly occurs. In addition, the deformation heat of the blank makes the blank and the metal chips deposited on the die surface, resulting in scratches on the surface of the workpiece.
