【摘要】：正1问题的提出凸凹模配合间隙与模具的使用时间(冲裁次数)和冲件的断面干净(毛刺大小)及锥度有直接的关系。因此在使用过程中,这种情况得用刃磨来解决。为了延长使用时间就要加厚凹模的厚度尺寸,可是在实际使用过程中,冲件断面由于材料内部金属颗粒在强大压力突然消失的情况下,会有弹性回跳现象,使冲件的断面尺寸比凹模的内径尺寸变大,这时冲件与凹模内壁产生磨损,凹模内孔尺寸逐渐变大,
[Abstract]:It is pointed out that the matching clearance of convex and concave die has a direct relationship with the working time of die (number of blanking) and the clean section (burr size) and taper of punching parts.Therefore, in the process of use, this situation has to be sharpened to solve.In order to prolong the service time, the thickness dimension of the thickening die is required. However, in the process of practical use, when the metal particles inside the material suddenly disappear under the strong pressure, there will be an elastic rebound phenomenon.The cross section dimension of the punch is larger than that of the die, and the inner wall of the die is worn out, and the size of the inner hole of the die increases gradually.
