Abstract：

In order to improve the processing capacity of mouldless rolling equipment and roll the discal part with larger sizes, for the rolling head being the key part of rolling equipment, a new structure model of rolling head was proposed according to the research goal, and it was analyzed and simplified according to its loading characteristics during the rolling process, finally, the expected loading on the rolling head was calculated by hypotheses. Then, the finite element analysis was conducted by software ANSYS Workbench, and the stress and deformation of the rolling head under expected conditions were obtained. The results show that the stress of the new rolling head meets the requirements, but its deformation is too large to meet the requirements. Based on this, it was improved by two different methods, and two optimized rolling head structures were obtained and analyzed by finite element method. Finally, the rolling head structure of the second optimization scheme meets the expected requirements and solves the problem of excessive deformation after the rolling head is loaded previously, which enables the key parts of rolling equipment, namely the rolling head, to match the target processing capacity of equipment and also guarantees the safety of rolling equipment.
