Abstract

The conventional methods for processing disc cam has many problems such as low material utilization and production, long processing cycle etc. A new rolling method was tried, and a three-dimensional finite element model of rolling process with several passes was obtained by different roll gaps and constant groove based on DEFORM. After simulating the hole filling degrees of the rolled parts with different total elongation coefficients, the best rolling pass of two was determined, and after simulating hole filling degrees and deformation degrees of the rolled parts with different billet diameters, the best billet diameter of Φ72 mm was determined. In the Ф160 mm×200 mm mill, 40Cr cam rolling process with the optimal rolling pass and billet diameter was experimented. The structure distribution of experimental rolled part is consistent with the simulated distribution of the effective strain, which proves that the simulation results are accurate.
