Abstract：

Through a stamping process analysis on the structure of back side panel, a layout scheme of a progressive die for the part including five-step bending was determined. The overall structure and design of main parts of die with multi-position punching and bending were presented. The section view drawing of five-step bending was showed serially. To assure the bar strip moving synchronously and running smoothly, lifting guide devices were used. The design scheme of progressive die was determinate.The molds took full advantage of the structural characteristics of workpiece itself, and adopted discharging automatically process, material giving out and less waste material blanking, which availably improved material utilization. The results show that the layout scheme and the 12 position progressive die are reasonable and feasible, and the quality of bending parts is guaranteed, which suitable for large-scale production of back side panel parts.
