根据皮带轮壁厚不均匀且带有双向凸台的结构特点，对其进行冲锻成形工艺研究。利用有限元软件Deform-3D对冲锻阶段金属的流动、成形缺陷及成形载荷进行模拟分析，并采取在冲锻模上模增加不同高度分流槽的形式来降低成形载荷。结果表明，对于双向凸台皮带轮可以采用冲锻成形工艺来成形；在分流槽高度为2mm时，成形效果良好，成形载荷较小。
根據皮帶輪壁厚不均勻且帶有雙嚮凸檯的結構特點，對其進行遲鍛成形工藝研究。利用有限元軟件Deform-3D對遲鍛階段金屬的流動、成形缺陷及成形載荷進行模擬分析，併採取在遲鍛模上模增加不同高度分流槽的形式來降低成形載荷。結果錶明，對于雙嚮凸檯皮帶輪可以採用遲鍛成形工藝來成形；在分流槽高度為2mm時，成形效果良好，成形載荷較小。

The stamping-forging hybrid forming process was analysed based on the structure characteristics, including non uniform wall thickness and bidirectional boss of the pulley. By the FEM software Deform-3D, the metal flow, forming defect and load in stamping-forging hybrid forming process were analysed. Diffluent troughs with different heights in the top die were used to reduce the forming load. As a result, stamping-forging hybrid forming was available for pulley with bidirectional boss, the load and forming result was satisfactory when the height of diffluent trough is 2mm.
