摘　　要：浪形保持架原整形模具由于结构复杂,模具各个部件组装后累积误差大,使得冲压过程中容易出现保持架兜孔尺寸精度、位置精度及饱满度超差的情况。针对上述问题,改进了模具结构,减掉了整形工序退料板,采用在钢球座上加退料销退料的模具结构,减少了模具的加工成本、组装、调整时间和模具的制造难度。The accumulated error of assemblies of primary dressing mold for ribbon cage is big because of complex structure, so as to make dimension accuracy, position accuracy and plumpness out of tolerance. For the above problems, the mold structure has been modified to remove the unloading plate replaced with an unloading pin on ball housing so as to make the mold’s processing cost, assembly, adjusting time reduce and manufacture easier.
