摘要: Based on the precision roll forging of one coupler yoke, the key problems of controlling the length of precision roll forgings were researched firstly with response surface method (RSM) and finite element method (FEM). First of all, in order to meet the appropriate length of roll forgings and reduce the maximum torque of roller, the second-order analysis model combined RSM and FEM was established in FORGE3 program, and the influences of roller clearance, friction factor, roller speed and billet temperature on the length of roll forgings and the maximum torque of roller were studied. Secondly, the roll forging was simulated with optimized process parameters, the principle of debugging the length of roll forgings was firstly presented, the roll forging dies were redesigned using the principle and point anti-tracking technology, and the lengths of designed, simulated and produced roll forgings and the power dissipation and distribution in one roll process were analyzed. The contrastive results of optimized simulation and products indicate that using RSM and FEM can accurately and effectively grasp the technology of controlling the length of precision roll forgings.
