Design and Experimental Verification of Hot Forging Die with Resistance Continuous Heating

In order to enhance product quality and simplify forming process,a new die structure which can make the forging finish heat and form in the die continuous resistance heating was investigated.The die structure was classified according to the relationship between the electrode and the billet.Taking the die structure,in which the electrode doesn't contact with the billet,as an example,the feature and the forming process were analyzed.The research was verified by experiment.The results show that the billet could be quickly heated to forming temperature.During the forming process,the billet cooling rate effectively decreases.
