沖模的結構設計應充分考慮配用壓力機的結構型式、,,技術狀態及動態精度。沖制中小型板料沖壓件,海內多使用公稱壓力PG≤2500KN的國產開式壓力機,包括:

(1)J11、J12XILIECHONGCHUANGJIQIGAIXINGYUGAIJINSHEJIDEKAISHIDANZHUGUDINGTAI、LIUDONGTAIYALIJI。QIGONGCHENGYALIPG≤2500KN;

按照JB/T6580-93《開式沖床壓力機精度》行業尺度,,,山东11选5公稱壓力PG≤2500KN的開式壓力機出廠精度都須符合劃定的檢測項目及其允差。

不少工廠用于沖壓中小型沖壓件的國產開式沖床壓力機已使用多年,,,超期服役相稱普遍。其靜態精度遠低于相稱項目實測誤差均超過表列允差,出廠精度早已喪失,實際運行承載后的動態精度就更低了。
