Research on forging simulation of spiral bevel gear blank
The hot forging process of spiral bevel gear blank is completed at high temperature, and the metallographic structure of metal will change at high temperature. At the same time, heat treatment is also required for the blank after forging. It can be further studied in combination with the change...

Simulation of forging forming of spiral bevel gear blank
Taking the forging process of driving and driven spiral bevel gears as the research object, the forging process of gear blanks is numerically simulated with the help of the finite element numerical simulation software from-3d. The main work and conclusions are as follows: Multi-step analysis method for numerical simulation...

Analysis of stroke load curve in the total forging process of spiral bevel gear blank
The stroke load curve of the die in the general forging process of the spiral bevel gear blank is shown in Figure 1. The overall forming process includes two stages: upsetting and die forging. Figure (a) shows that the load at the beginning of the upsetting process is 0t,...

Numerical simulation of forging process of driving spiral bevel gear blank
The CAD two-dimensional drawing of the upper and lower molds is shown in Figure 1. 1.Mold geometric model establishment According to the two-dimensional drawings of the upper and lower molds, the 1/4 geometric model of the upper and lower molds is established, as shown in Figure 2. 2.Establishment of...

Analysis of stress-strain and temperature variation with time in forging process of spiral bevel gear blank
In the DEFORM-3D post-processing function, the time-dependent curves of the equivalent stress-strain and temperature at a certain point of the spiral bevel gear blank can be obtained. However, the change curve of each point is different, and there is no strong regularity. Therefore, only three representative points are taken...

Precision forging of spiral bevel gear blank
Although a lot of research has been done on precision forging of spiral bevel gears at home and abroad, there are still some problems in the process of applying it to production practice: high requirements for moulds. The tooth profile of spiral bevel gear is complex, which determines that...

Influence of die structure of spiral bevel gear forging blank on forming effect
Through the stress-strain analysis and temperature analysis of the spiral bevel gear blank after hot forging, we know that the metal material is difficult to flow at the two steps of the die, one of which is the step between the outer side of the spiral bevel gear blank...
