防尘盖轴承压盖模具改进

Improvement on gland mould for dust cover bearing

通过对防尘盖轴承压盖后外径变形原因的分析后发现,模具结构是造成外径变形的原因,故对该模具进行了改进设计,将压盖工序对产品外径变形影响降至最低限度,达到了降低废品率的目的。

It was found that the mould structure was the cause of of outer diameter deformation after the dust cover bearing gland that the effect of gland process on product diameter deformation deformation of outside diameter through analyzing the cause , therefore the improvement design to this mold was made so dropped to the minimum to achieve the goal of reducing the rejection rate.
