Study on Bending and Upsetting Forging 305 Marine Crankshaft

Abstract:

Roll-over of crank arm is the major defect of forming quality during the upsetting process. Bending and upsetting forging of crankshaft was simulated by using the rigid-plastic finite element model. The theories of metal flowing and distribution of deformation during the bending and upsetting forging were analyzed, the root cause of the roll-over of crank was found; the optimal combination of the bending and upsetting velocities was obtained; the experimental results agree well with simulations.
