SIMULATION ANALYSIS OF WHEEL BEARING FORGING PROCESS BASED ON DEFORM

Aiming at the complex structure of wheel hub bearing parts, which is difficult to form, an upsetting-pre-forging- final forging forming process is adopted after process analysis. A three-dimensional finite element model is established by Deform software to study the process of wheel hub bearing forging, and the distribution law of temperature field, equivalent stress field and other important fields in the forging process are systematically analyzed. The influence of forging process parameters on the forming quality of wheel hub bearings is studied. Based on the results of Deform simulation, the optimal forging process parameters are used in the actual forging production, and the forging parts obtained have clear hierarchical levels in each region and good forming quality. The experiment verifies that the forging is complete and meets the product requirements under the optimized process parameters, which provides theoretical and technological guidance for the hot die forging of wheel hub bearing parts.
