齿轮锻造工艺设计说明书（Gear forging process design manual）Gear forging process design manual
Abstract: the purpose of forging blank molding, and control of its internal organizational performance reached the desired geometry, size and quality of forgings, steel and non-ferrous metal and alloy has the most plastic in different degrees, can be plastic molding process in cold or hot. The forging of gears adopts the free forging process. This paper mainly introduces the free forging process of gears. Free forging is the use of pressure or impact force is the metal between the upper and lower iron deformation between plastic deformation, so as to obtain the shape and size of the required method. The determination of free forging becomes the key to free forging. This article focuses on the process of free forging of gears.
Keywords: free forging, gear processing, plastic deformation, process flow.
