Filed: 2000-02-10
Abstract: PROBLEM TO BE SOLVED: To improve the filling property of a counterweight by effectively suppressing the out-flow of burrs without increasing the forging load. SOLUTION: A crankshaft is forged by flowing out burrs on the flange side from the position shifted to either side in the vertical direction of the axis 5 of symmetry of the burr out-flow by using a rough die 11 in which a burr out-flow portion in the longitudinal direction on the flange side in upper and lower dies is shifted to either side of the axis 5 of symmetry of the burr out- flow in the vertical direction. The filling property of the counterweight can be improved by effectively suppressing the out-flow of the burrs without increasing the forging load, and thus, the underfill is prevented, and the yield is improved.
