(1)Metal flow law in extrusion process
The metal velocity vector diagram of each stage in the extrusion process of spiral bevel gear blank is shown in Figure 1. Fig. 1a is the metal flow velocity vector diagram at the beginning of the extrusion process, FIG. 1b to Fig. 1E are the metal flow velocity vector diagram of the intermediate process, and Fig. 1F is the metal flow velocity vector diagram at the completion of the extrusion process.
(1)Analysis of numerical simulation results after extrusion
The equivalent stress-strain and temperature distribution of spiral bevel gear blank after extrusion are shown in Figure 2. After extrusion, the equivalent stress of spiral bevel gear blank is between 3-537mpa, the equivalent effect is between 0-1.58, and the temperature is between 443-755 ° C.
