High strength steel has high strength and poor plasticity. When it is used in parts with large material thickness, complex shape and many working procedures, higher requirements are put forward for mold design. This paper introduced the forming characteristics, layout scheme, overall structure design of multi-station progressive die and design key points of important parts of a high-strength steel plate car mounting part. The progressive die including blanking, drawing, local forming and bending and other 13 processes was designed. The preforming and secondary forming were adopted to form the reinforcing ribs. The double-row with center carrier layout pattern was adopted to reduce the bending side force, and made the material utilization higher. The sub-die and insert structure’s using was convenient for die machining and debugging. The practice has proved that the die structure is reasonable and reliable, which can guarantee the quality of the products. It can be used as a reference for the design of similar products.
