合理的模具設(shè)計(jì)。在級(jí)進(jìn)模中,下料順序的安排有可能影響到?jīng)_壓件成形的精度。針對(duì)沖壓件細(xì)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(duì)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(shè)計(jì)的沖壓件必須形狀簡(jiǎn)單，結(jié)構(gòu)合理，以有利于簡(jiǎn)化模具結(jié)構(gòu)、簡(jiǎn)化工序數(shù)量，即用少、簡(jiǎn)單的沖壓工序完成整個(gè)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(shí)現(xiàn)機(jī)械化與自動(dòng)化生產(chǎn)，以高勞動(dòng)生產(chǎn)率。

設(shè)計(jì)的沖壓件，在保證能正常使用情況下，盡量使尺寸精度等級(jí)及表面粗糙度等級(jí)要求低一些，并有利于產(chǎn)品的互換，減少廢品、保證產(chǎn)品質(zhì)量穩(wěn)定。

設(shè)計(jì)的沖壓件，應(yīng)有利于盡可能使用現(xiàn)有設(shè)備、工藝裝備以及工藝流程對(duì)其進(jìn)行加工，并有利于沖模使用壽命的延長(zhǎng)。

增設(shè)強(qiáng)壓功能。即對(duì)卸料鑲塊壓料部加厚尺寸(正常的卸料鑲塊厚H 0.03mm)，以增加對(duì)凹模側(cè)材料的壓力，從而抑制沖切時(shí)沖壓件產(chǎn)生翻料、扭曲變形。

Additional pressure function. In order to increase the pressure on the material of the die side, the pressure of the material in the die side is increased by the thickness of the material of the unloaded insert (normal unloaded insert thickness H 0.03mm), so as to suppress the turning and distortion of the stamping parts.

深縫：鋸削深縫時(shí)即當(dāng)鋸縫的深度超過鋸弓高度時(shí)，高度時(shí)，鋸弓就會(huì)與工具相碰，無法繼續(xù)鋸削；此時(shí)應(yīng)將鋸條拆出，將鋸條轉(zhuǎn)90。

Deep seam: when sawing deep seams, when the depth of the sawblade exceeds the height of the saw bow, when the height is high, the saw bow is touched by the tool and can not continue to be sawed; the saw strip should be removed and the saw blade is turned 90.
