Embodiment Construction
[0019] The following combination Figure 1 ~ Figure 3 And specific embodiments, the present invention is described further. It should be understood that the following examples are only used to illustrate the present invention but not to limit the scope of the present invention.
[0020] The concrete steps that the present invention implements are as follows:
[0021] 1) Deform simulation using process simulation system: simulate the entire processing process on the computer, analyze various forming processes and heat treatment processes in metal forming and related industries, and then simulate and optimize punches and adjust the fit gap between molds;
[0022] 2) Simulation and display of streamline distribution: Use carburized steel with low purity to replace the newly developed DZC1 carburized bearing steel with high purity to manufacture forgings with the same structure and size. Carry out wire cutting processing in the height direction of the ferrule, and after grinding...
