Process Design for Cold Precision Forging of Bevel Gear

摘要：

Precision forging is defined as a near net-shape forging operation which generates high quality parts concerning surface quality and dimensional accuracy. In particular gears offer a wide application field for the precision forging technology. Advantages like shortened production cycles achieved by eliminating machining operations and the saving of raw material contribute to the ongoing cost-saving trend in the industry. This article describes the adopted methods and the precision forging process of the bevel gear. 3D FEM model of the precision forging process of bevel gear was established. The forming laws, material plastic behavior, changed geometries and the qualities of the gears are explored by finite element simulation. Completely filled gear teeth were obtained using a lower forging load by the designed process which is the effective forging process for manufacturing of bevel gear. The design process for bevel gear has to be purpose-built to consider the distinctions of this precision forging technique.
