暖风机除霜接口冲压工艺设计

分析了暖风机除霜接口零件的冲压生产工艺,在生产技术准备工作中用倒推法对工艺顺序进行了合理编排,对各工序的形状和尺寸进行了分析和计算,对宽凸缘零件拉深进行了详细计算;各工序间的坯料尺寸计算较为关键,它对其后工序的形状会产生较大影响;修边工序的准确轮廓尺寸可通过试验获得,以保证最终产品口部平直的要求;在成形锥度形状时,从模具结构上尽量保证制件坯料处于径向、切向受拉厚度方向受压的应力状态.本零件结构独特,工艺方案复杂,工序较长,对同类型产品工艺制定具有借鉴作用和参考价值.

Punching process design on defrosting conection of heater unit

; Punching production process of the defrosting connection components of heater unit was analyzed, the proce-dure order with counter-pushing method in the technology preparatory work was rationally arranged, the shape and the size of working procedures were analyzed and calculated, and the drawing of width flange components was calculated i ndetail. The blank size calculation of working procedures is the key, and it could cause major impact to subsequent processes. To ensure a fiat mouth shape of final product, accurate boundary dimension of trimming procedure could be got by testing. In forming taper shape, the work-blank had a stress state that its radial direction and tangential direction were pulled and thickness direction was pressed. This component had a unique structure and was of complex processing plan and long working procedure. The result has the model function and the reference value to the same type product.
