Abstract：

In this paper, we studies the plastic forming technology of the horse shoe which is made by 6061 aluminum alloy and simulates the forming process which runs in DEFORM 3D software. From the simulation results, we found the insufficient forming at the top of the part. So we improve the die structure to control the material flow and simulated again and the material flows effectively. It has been shown that finite element simulation can improve the forging process design level greatly.
