Abstract：

Pointing to the characteristic of G2500 crank shaft that the crank width is much bigger and it is difficult to fill forging die, the technology of first roll forging and then die forging was adopted, and the flow of metal and change of press tonnage press during the die forging process of designed four kinds of G2500 crank shafts were studied by numerical simulation. That the ideal roll forging blank is roll forging workpiece 4 is determined under the condition of assuring the good filling of die forging cavity, fully filled crank and satisfied tonnage of die forging equipment. Finally, the result of the numerical simulation was tested by actual production. It proves that actual production and numerical simulation are coincident, and the G2500 crank shaft with good quality can be obtained by using 8000 t hot forging press and adopting rational dimension of roll forging workpiece．
