在装配冷冲模时,凸凹模的间隙是否均匀一致将直接影响冲压件的质量。我厂过去在制造电机定子扇形片冲模时,当模具制造完后,检查间隙大体上一致,只有局部或大或小,但仍在合理的间隙(最大与最小间隙)之间。可是当试模时,局部出现小毛刺。为了解决冲模间隙的均匀性,可采用如下方法: 首先加工好的凸、凹模用汽油洗净,然后在凸模上涂一层均匀的漆片溶液(即漆片5％+酒精95％),待干后将凸模试插入凹模约4～8mm,以不能
Die assembly in the cold, punch and die gap is uniform will have a direct impact on the quality of stamping parts. In the past, when manufacturing the motor stator segment die, the inspection clearances were basically the same after the molds were manufactured, only partial or large but still within a reasonable clearance (the maximum and minimum clearances). However, when the test mode, a small local burr. In order to solve the uniformity of the die gap, the following method can be used: First, the processed convex and concave mold washed with gasoline, and then coated with a uniform coating solution on the punch (ie, 5% of the paint + 95% alcohol) , To be dry after the punch into the die about 4 ~ 8mm, can not
