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...
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...
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,...
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...
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...
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...
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...
1、 Establishment of geometric model Using pro/e4.0, the geometric model of extrusion process is established, including the geometric model of upper and lower dies and the geometric model of spiral bevel gear blank. According to the drawings provided by the enterprise, the blank of spiral bevel gear is Φ...
Due to the problems in the free forging process of the cutting block, other forming methods are considered to replace the free forging of the cutting block to achieve the purpose of drawing. The following two forming methods are considered to replace the free forging of cutting block to...
