Abstract：

This paper deals with the problem of making a forged article such as the crank of gasoline engine,which consists of a big disc and a long thin rod.Through making a comparison between the common pre-blocking techniques and forming technology,the author finds that it is an ideal plan to adopt cross wedge rolling technique for pre-blocking and then implementing forging operations.This paper puts forward a rolling and forging combined process of the crank of gasoline engine,which proceeds from productive requirements.By this means,the author tries to introduce an designing idea which combines wedge-rolling tools in the performing process,to probe into the method of combined wedge-rolling tools design,and bring practical values to the rolling and forging combined process of the crank.
