Calculation Results

Taking the geometric configuration of complex-shape forging into account, the isothermal split-die forging method, which is one multi-way die forging technology and can be operated on the general hydraulic press, is employed. The temperatures of billed and dies are 420°C and 380°C in the isothermal forging process. The coupled thermo-mechanical finite element method (FEM) is used to analyze the forging process. FEM calculation results show several folds had been formed in the final forging process due to unreasonable geometric configuration of preform. The folds mechanism is that direction of velocities become cross on the surface of billet, and the folds can be avoided if the direction would be kept convex. And then the preform is redesigned. A set of isothermal precision forming equipment is designed and manufactured. The experimental results verify the selected process and preform configuration. And all of the hardness, dimensional accuracy and surface quality of the forgings obtained by the equipments satisfy the requirements.

Cold Precision Forging

The cold forging process of large module spur gear with four modules and 59mm breadth is performed by means of numerical simulation method. Two processes to forming such spur gears were compared by the simulation method, one is with the closed-die performing and extrusion in the finish-forging, the other is with divided-flow method in the finish-forging. Especially, the divided-flow method is analyzed in detail. The necessary reference and basis to realize practical cold precision forging process of spur gear with large modulus is provided eventually.
