Example Embodiment
[0016] The invention relates to a processing method for a high-precision forging of a wheel hub of a revolving forged truck, such as figure 1 — Figure 4 shown, characterized by:
[0017] ①, heat the aluminum rod, take the aluminum rod 1, and use the aluminum rod heating furnace to heat the aluminum rod for 3 hours, and heat it to 420°-480°;
[0018] ②, upsetting the aluminum rod, take a hydraulic press, the upper molding plate 2 and the lower molding plate (3) are set in the hydraulic machine, the preset height of the upper molding plate is 150mm, and the pressure is 2000 tons, and the heated aluminum rod is subjected to molding and upsetting. get rough 4;
[0019] 3. Rotary forging, take the rough blank 4 and put it into the rotary forging machine. The rotary forging machine includes the first upper die base 5 and the first lower die base 6, and the first upper die is installed under the first upper die base. 8. The first upper mold base 5 and the first upper mold 8 are f...
