彎曲工藝的概念及彎曲件1．彎曲工藝：是根據零件形狀的需要，通過模具和壓力機把毛坯彎成一定角度，一定形狀工件的沖壓工藝方法。 2．彎曲成形工藝在工業生產中的應用：應用相當廣泛，如汽車上很多履蓋件，小汽車的柜架構件，摩托車上把柄，腳支架，單車上的支架構件，把柄，小的如門扣，夾子（鐵夾）等。 彎曲的基本原理：以V形板料彎曲件的彎曲變形為例進行說明。其過程為： 1． 凸模運動接觸板料（毛坯）由于凸,凹模不同的接觸點力作用而產生彎矩， 在彎矩作用下發生彈性變形，產生彎曲。 2． 隨著凸模繼續下行，毛坯與凹模表面逐漸靠近接觸，使彎曲半徑及彎曲力臂均隨之減少，毛坯與凹模接觸點由凹模兩肩移到凹模兩斜面上。（塑變開始階段）。 3．隨著凸模的繼續下行，毛坯兩端接觸凸模斜面開始彎曲。（回彎曲階段）。 4．壓平階段，隨著凸凹模間的間隙不斷變小，板料在凸凹模間被壓平。 5． 校正階段，當行程終了，對板料進行校正，使其圓角直邊與凸模全部貼合而成所需的形狀。 彎曲變形的特點： 彎曲變形的特點是：板料在彎曲變形區內的曲率發生變化，即 彎 曲半徑發生變化。從彎曲斷面可劃分為三個區：拉伸區、壓縮區和中性層。
