⑴設(shè)計(jì)的沖壓件必須滿(mǎn)足產(chǎn)品使用和技術(shù)性能，并能便于組裝及修配。

⑵設(shè)計(jì)的沖壓件必須有利于提高金屬材料的利用率，減少材料的品種和規(guī)格，盡可能降低材料的消耗。在允許的情況下采用價(jià)格低廉的材料，盡可能使零件做到無(wú)廢料及少?gòu)U料沖裁。

⑶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。

簡(jiǎn)單來(lái)說(shuō)鈑金件是金屬薄板殼體，沖壓件就是用拉伸機(jī)或沖床等加工的工件1，鈑金件在折彎過(guò)程中厚度不會(huì)有變化，但在汽

車(chē)鈑金殼體中應(yīng)為敲擊等原因，一部分表面會(huì)有一定變化。沖壓廠(chǎng)是不能確定落料尺寸的，應(yīng)該是在定做模具時(shí)由模具廠(chǎng)試定出來(lái)的。

In a simple way, the sheet metal part is a metal sheet shell, and the stamping part is 1 of the workpiece, which is processed by a drawing machine or a punch press. The thickness of the sheet metal parts will not change during the bending process, but in the steam.

The surface of the automobile shell should be knocked and so on. Part of the surface will change. The stamping plant is unable to determine the blanking size. It should be determined by the mold factory when making the mould.

日常模具生產(chǎn)中，應(yīng)注意維護(hù)沖切凸、凹模刃口的鋒利度。當(dāng)沖切刃口磨損時(shí)，材料所受拉應(yīng)力將增大，從而沖壓件產(chǎn)生翻料、扭曲的趨向加大。

In daily mold production, attention should be paid to sharpness of punching and concave die edges. When the cutting edge is worn, the tensile stress of the material will increase, and the stamping and bending will increase.

深縫：鋸削深縫時(shí)即當(dāng)鋸縫的深度超過(guò)鋸弓高度時(shí)，高度時(shí)，鋸弓就會(huì)與工具相碰，無(wú)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.
