合理的模具設計。在級進模中,下料順序的安排有可能影響到沖壓件成形的精度。針對沖壓件細小部位的下料,一般先安排較大面積之沖切下料,再安排較小面積的沖切下料,以減輕沖裁力對沖壓件成形的影響。
Reasonable mold design. In progressive die, the order of blanking sequence may affect the accuracy of stamping forming. In order to reduce the impact of punching parts, the punching and cutting blanking of small area is arranged in the light of the blanking of the small parts of the stamping parts.
設計的沖壓件必須形狀簡單,結構合理,以有利于簡化模具結構、簡化工序數量,即用少、簡單的沖壓工序完成整個零件的加工,減少再用其他方法加工,并有利于沖壓操作,便于組織實現機械化與自動化生產,以高勞動生產率。
設計的沖壓件,在保證能正常使用情況下,盡量使尺寸精度等級及表面粗糙度等級要求低一些,并有利于產品的互換,減少廢品、保證產品質量穩定。

設計的沖壓件,應有利于盡可能使用現有設備、工藝裝備以及工藝流程對其進行加工,并有利于沖模使用壽命的延長。
壓住材料。克服傳統的模具設計結構,在卸料板上開出容料間隙(即模具閉合時,卸料板與凹模貼合,而容納材料處卸料板與凹模的間隙為材料厚t-0.03~0.05mm)。如此,沖壓中卸料板運動平穩,而材料又可被壓緊。關鍵成形部位,卸料板一定做成鑲塊式結構,以方便解決長時間沖壓所導致卸料板壓料部位產生的磨(壓)損,而無法壓緊材料。


Press the material. In order to overcome the traditional mold design structure, the clearance of material is opened on the discharge plate (i.e., when the die is closed, the discharge plate and the die are fitted, and the gap between the discharge plate and the die is t-0.03 to 0.05mm). In this way, the discharging plate moves smoothly, and the material can be pressed tightly. In the key forming part, the discharge plate must be made into an inlaid structure to facilitate the solution of the grinding (pressure) loss caused by the pressing part of the unloading plate for a long time, and the material can not be pressed.
