液化石油气钢瓶封头的落料模(尺寸见图)在使用中,由于刃口磨损,使凸模尺寸变小,凹模尺寸变大。当凸、凹模的间隙超过0.8mm时,就得更换新模具,我厂自生产钢瓶以来,已报废4个凹模、1个凸模。为节约材料和资金,我们将已报废的模具进行改制,从而节省了资金2万多元,具体做法如下:将4个四模内腔进行磨削,尺寸扩大到φ645_0~(+0.07)mm,并配制一个新凸模,尺寸为φ644.7_(-0.07)~0mm。又将废凸模尺寸磨削到φ643.7_(-0.07)~0mm,并配制两个新凹模,尺寸为
Liquefied petroleum gas cylinder head blanking die (size see picture) in use, due to the wear of the blade, the punch size becomes smaller, the die size becomes larger. When the convex and concave die gap exceeds 0.8mm, you have to replace the new mold, I plant since the production of cylinders, has been scrapped four die, a punch. In order to save materials and capital, we will have scrapped the mold for restructuring, thus saving more than 20,000 yuan of funds, as follows: The four four-cavity mold grinding, the size expanded to φ645_0 ~ (+0.07) mm, And the preparation of a new punch, the size of φ644.7 _ (- 0.07) ~ 0mm. Again the size of the punch punch grinding to φ643.7 _ (- 0.07) ~ 0mm, and the preparation of two new die, the size of
