不锈钢冲压件加工中存在的难题

不锈钢冲压件加工中存在的难题。
Difficulties in the processing of stainless steel stamping parts.
第一，由于不锈钢冲压件硬度高，不容易拉伸。在冲压是如果模具设计不合理，变形度过大，容易出现裂口；
First, because of the high hardness of stainless steel stamping parts, it is not easy to stretch. In stamping, if the die design is unreasonable, the deformation degree is too large, and cracks are easy to appear.
第二，不锈钢冲压件屈服点高，所需冲切力大，对模具设计和模具材料的要求较高。模具不合理或模具的材料较差那在生产中容易爆模，造成生产停滞；
Secondly, stainless steel stamping parts have high yield point and large punching force, which require high requirements for die design and die materials. Mold is unreasonable or the material of the mould is poor, which is easy to burst in production, resulting in production stagnation;
第三，不锈钢冲压件变形度大，容易产生表面起皱；
Thirdly, stainless steel stamping parts have large deformations and are prone to surface wrinkles.
第四，模具易出现粘结瘤，导致不锈钢冲压件加工时常出现划伤和压痕；
Fourthly, the die is prone to sticking nodules, which often lead to scratches and indentations in the processing of stainless steel stamping parts.
第五，不锈钢冲压件模具设计时要计算好材料回弹系数，不然会导致不锈钢冲压件很难达到预期的结构。
Fifth, the springback coefficient of materials should be calculated well in the die design of stainless steel stamping parts. Otherwise, it will be difficult for stainless steel stamping parts to achieve the desired structure.
