不銹鋼沖壓件加工中存在的難題。
Difficulties in the processing of stainless steel stamping parts.
第一，由于不銹鋼沖壓件硬度高，不容易拉伸。在沖壓是如果模具設計不合理，變形度過大，容易出現裂口；
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，不銹鋼沖壓件屈服點高，所需沖切力大，對模具設計和模具材料的要求較高。模具不合理或模具的材料較差那在生產中容易爆模，造成生產停滯；
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，不銹鋼沖壓件變形度大，容易產生表面起皺；
Thirdly, stainless steel stamping parts have large deformations and are prone to surface wrinkles.
第四，模具易出現粘結瘤，導致不銹鋼沖壓件加工時常出現劃傷和壓痕；
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，不銹鋼沖壓件模具設型槽模具 一次性止血帶 保定水處理設備 一次性止血帶 保定空壓機 北京真空泵計時要計算好材料回彈系數，不然會導致不銹鋼沖壓件很難達到預期的結構。
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.
