Abstract：

The advantages and disadvantages of forging forming and twisting forming for crankshaft were briefly compared. Based on the development example of Hongqi V6 crankshaft, the product characteristics of Vstyle twist crankshaft were described, and the forging process was discussed and summarized. For the problem of being prone to folding on V6 twist crankshaft pin area when forging, the research methods of comparison test and simulation test were carried on, the reasonable process plan was selected, and the problem was solved. In terms of equipment selection, taking the existing production line of FAW forge company as example, the selection parameters of key equipments for twist press and walking beam were discussed in detail, and the twist step principle and twisting movement decomposition were expounded. The design difficulties of twist dieset and twist die were analyzed one by one, and the practical solutions were given.
