Abstract：

The warm-cold forming process of blanking\|extrusion-backward extrusion-finishing\|reduction was researched for BJ-type outer race by means of numerical simulation. Focusing on analysis of the material flow, temperature distribution as well as the load curve for the backward-extrusion process, a reasonable mold construction was obtained. The optimized temperature is 700900 ℃ for backward extrusion process and the load is 9000 kN. The above reasonable data for BJ-typed outer race offer favorable basis for forming and mold design.
