Rotary forging process of bevel gear

Bevel gear swing rolling, namely swing rolling, also known as axial rolling, is a new plastic processing technology gradually and widely used in production since the 1970s. Due to the unique processing mode and many advantages of this process, scholars and enterprises all over the world attach great importance to it. The process features are as follows:

(1) The mold of bevel gear rotary rolling has two parts. The active pressurizing part is the cone die (also known as the swing head), which is in local contact with the workpiece during machining and rolls or rolls on the workpiece.

(2) During bevel gear swing rolling, the local contact between the conical die installed on the swing head and the workpiece (as shown in the figure) is only 1 / N (n = 5-10) of the deformation area of the workpiece. The contact area is compressed axially and extended tangentially and radially. The contact surface moves continuously due to the swing of the die. When covering the whole deformation area of the workpiece, one feed cycle is completed, and multiple feed cycles are superimposed to complete the overall deformation required by the workpiece. It is equivalent to the eccentric load of the cone rolling deformation on the workpiece along the bus.

(3) Compared with the traditional plastic processing method, the motion forms of bevel gear rotary rolling are diverse and complex.

(4) The rotary forging process of bevel gear is mainly suitable for forming axisymmetric parts.
