不鏽鋼沖壓件表面劃痕形成的原因

網址:www.juhua584584.cn  2019-07-20  作者:admin    閱讀:

不鏽鋼沖壓件表面出現劃痕主要是由于工件和模具表面存在相對移動,在一定壓力的作用下,緻使坯料與模具局部表面直接産生摩擦,加之坯料的變形熱使坯料及金屬屑熔敷在模具表面上,使工件表面擦傷産生劃痕。
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.
