多接点密型接触环是我厂引进产品ELFSL4—2关键零件之一。过去一直依赖进口,为降低产品成本,实现零件国产化,遂组织力量攻关。该零件的冲制模具是典型的高难度微型零件冲压模以及是冲裁、弯曲和成形三组合的多工步变节距级进模。其中关键是要让模具步进方向三层密合叠合.改变级进模后工步的等距,给级进模后成形工步的定位和成形增加了难度,因此对各工步的动作提出了严格要求。
Multi-contact dense contact ring is one of the key parts of ELFSL4-2 introduced by our factory. In the past has been dependent on imports, in order to reduce product costs, to achieve localization of parts, then the organization power research. The parts of the stamping die is a typical difficult miniature parts stamping die and is blanking, bending and forming three combinations of multi-step variable pitch stepper die. One of the key is to make the mold stepping direction of the three-layer close together superimposed.Changing the step after the progressive die step equidistant to the progressive die forming step positioning and forming increased difficulty, so the steps of the action Put forward strict requirements.
