弯曲工艺的概念及弯曲件1.弯曲工艺:是根据零件形状的需要,通过模具和压力机把毛坯弯成一定角度,一定形状工件的冲压工艺方法。 2.弯曲成形工艺在工业生产中的应用:应用相当广泛,如汽车上很多履盖件,小汽车的柜架构件,摩托车上把柄,脚支架,单车上的支架构件,把柄,小的如门扣,夹子(铁夹)等。 弯曲的基本原理:以V形板料弯曲件的弯曲变形为例进行说明。其过程为: 1. 凸模运动接触板料(毛坯)由于凸,凹模不同的接触点力作用而产生弯矩, 在弯矩作用下发生弹性变形,产生弯曲。 2. 随着凸模继续下行,毛坯与凹模表面逐渐靠近接触,使弯曲半径及弯曲力臂均随之减少,毛坯与凹模接触点由凹模两肩移到凹模两斜面上。(塑变开始阶段)。 3.随着凸模的继续下行,毛坯两端接触凸模斜面开始弯曲。(回弯曲阶段)。 4.压平阶段,随着凸凹模间的间隙不断变小,板料在凸凹模间被压平。 5. 校正阶段,当行程终了,对板料进行校正,使其圆角直边与凸模全部贴合而成所需的形状。 弯曲变形的特点: 弯曲变形的特点是:板料在弯曲变形区内的曲率发生变化,即 弯 曲半径发生变化。从弯曲断面可划分为三个区:拉伸区、压缩区和中性层。
