(1) Forging material The forming metal material selected for the driven spiral bevel gear of automobile rear axle is a

1. Establishment of finite element model According to the structural diagram of closed cold finishing and open cold finishing, the

By changing the die structure and the cone angle of lead billet, the test is carried out on the universal

The three-dimensional geometric modeling of the punch and die is completed by ug-3 software, as shown in the three-dimensional geometric

When forming parts under cold extrusion, the selection of die materials for precision forming of spiral bevel gear should have

Among the designed parts, the tooth shape concave die of spiral bevel gear is the most critical part. Because the

Bevel angle of preform of spiral bevel gear α It has a great influence on the filling fullness of tooth

The shape of preform has a great influence on the cavity filling, material consumption and forming force of metal in

Under the condition of ensuring the same volume and shape of the preform of spiral bevel gear, the internal split

Because DEFORM-3D software does not have the function of 3D modeling, UG modeling software is used to establish the solid

At present, the main processing method of spiral bevel gear is cutting method, and its whole production process is: blank

The pitch tooth line is a curve. This determines that when the teeth mesh, each pair of teeth can only

20CrMnTi gear steel is used for precision forging driven spiral bevel gear, and lead is selected as the simulation material.

The forming process of spiral bevel gear can be divided into three stages. The initial stage of deformation is at
