Hot Forging Process

The rigid-visco-plastic finite element model for the hot forging process of transmission shaft flange yoke was established, and two forging schemes of different male die shapes were simulated. As for the present forming process, the forming defects were indentified and analyzed. Based on the simulating results the decision-making process was obtained, and a preforming die and a final forming die with proper structures and longer life were designed. The transmission shaft flange yoke part produced by this process is excellent in dimension tolerance and mechanical property. This process is profitable reference for producing the similar type of forks with complex shape.

This paper demonstrates the development of a technology for low-waste zero-draft hot forging of axisymmetric parts, in particular, welding neck flanges, on the basis of an expansion-extrusion deforming procedure. In this study, we carried out a process simulation by means of DEFORM 3D for a qualitative evaluation of the plastic yield. Based on the simulation results, the method was proven feasible, and we set forth the goal to prepare the process and design guidelines for further industrial application. The region of plastic deformation was determined, and a general view of the function for determining kinematic parameters was given according to A.L. Vorontsov’s procedure. The force parameters of the zero-draft hot forging process by the combined expansion-extrusion procedure were analyzed by studying the kinematic conditions of the forging. The general function for determining the force parameters was found.

Forging process is one of the most basic metal forming processes. In this study a new forging process is applied to fabricate a precision forging product uniting parking and driven gears in order to obtain lightweight and cost effectiveness of an automobile. Since the united product using the precision forging process needs high quality and new manufacturing process, 3D computer simulation by FEM has been used to reduce some trial and errors in experiment and obtain the deformation, strain, stress and load of the workpiece and die. The study has tried to find out an optimal process including preform design putting emphasis on tooth filling by DEFORM-3D, a 3-dimensional rigid-plastic finite element code.
