Analysis of die stress and forging force for DIN 1.2714 die material during closed die forging of anchor shackle

In hot forging the dies are subjected to the high temperature and contact pressure. The selection of die material is based on the ability to retain the hardness and toughness at elevated temperature. The chromium die steel material retain their hardness upto 425 0C. The die life is not only depend on the material used but also on the process parameters like preform size, number of blows, forging force, temperature, coefficient of friction and so on. To enhance lifecycles of dies the die stress and forging force should be minimized during closed die forging process. Preliminary geometry of the component which is transformed to concluding geometry in forging is known as preform and the die stress and forging force are depended on the preform size and shape. In this paper DIN 1.2714 die steel material is considered for a finite element analysis to observe the effect of preform size on die stress and forging force during closed die forging of anchor shackle which is used in transmission line.
