摘要：

通过对某微波炉ELG外壳的冲压工艺分析及计算，提出了针对该制件采用双侧载体及内、外圈3个方向搭边的排样方案。介绍了该制件的整体模具结构及主要部位的局部机构设计，并对整形工序中的凸模微调装置机构及调整动作进行详细说明，每调整1次可在10 min以内完成，大大节省了模具调试时间。在排样设计中，充分利用带料毛坯外圈的搭边形状特点，将其中1个方向的搭边设置在两个制件之间的对应位置，可以减短步距而不影响带料刚度，从而有效提高材料利用率。为确保带料在连续拉深后送料畅通，该模具在带料两侧设置了浮动导料销装置。冲压实验结果表明，所设计的模具结构紧凑，冲压制件质量良好，可以满足大批量生产需求。

According to stamping process analysis and calculation for microwave ELG shell, the layout plan for sides in three directions of a two-sided carrier and inner and outer rings was presented. The overall die structure and the local mechanical design of the key parts were introduced and the punch fine-tuning device and adjustment action in shaping process were described in detail. Therefore, each adjustment could be completed within 10 min which saved the adjustment time of the die greatly. In layout design, considering the characteristics of the side shape with outer ring blank, the side location of the one of directions was designed in the corresponding location between the workpieces, and the step was shortened without influencing the strip stiffness. Therefore, the utilization rate of the material was improved. In order to ensure the continuous feeding smoothly after deep drawing, the floating guide pin devices were designed on both sides of the strip in the die. The experimental results show that the compact die design and good quality stamping parts can meet the needs of mass production.
