摘　　要：通过对6700轻卡转向节的结构与特点分析,结合多向挤压精密模锻的特点制定了它的工艺方案并进行了模具设计。模锻工艺包括下料、挤杆、劈挤叉部和多向精密模锻。采用Deform-3D软件对成形过程和速度场进行了分析,得到了锻件的成形规律。这对转向节的多向精密模锻锻具有指导意义。Through the analysis of structrue and characteristics for 6700 steering knuckle, its technology project was constituted by combining the characteristics of the multi-directional precision die forging, and the die was designed. The technology of die forging includes blanking, extrusion rod, splitting extrusion fork and multi-directional precision die forging. The forming process and velocity field were analyzed by using Deform-3D sottware.The forming law the forging was obtained. This has guiding significance for multi-directional precision forging of steering kunckle.
