幫助確定成形零件毛坯形狀、尺寸及用料標準：在沖模設計中，有些形狀復雜或精度要求較高的沖壓成形零件，很難在設計時精確地計算出變形前毛坯的尺寸和形狀。為了要得到沖壓加工較準確的毛坯形狀、尺寸及用料標準，只有通過反復試沖才能確定。 </p> <p> <br /> </p> <p> 幫助確定沖壓加工工藝和模具設計中的某些尺寸：對于形狀復雜或精度要求較高的精密沖壓成形工件件，在工藝和模具設計中，有個別難以用計算方法確定的尺寸，如拉深模的凸、凹模圓角半徑等，需經過試沖，才能確定。只有通過調試發(fā)現(xiàn)問題，解決問題，積累經驗，才能有助于進一步提高模具設計和制造水平。 </p> <p> <br /> </p></p><br /><p>文章來源地址:
