Embodiment 1

[0036] A pure aluminum billet with a diameter of 40mm and a length of 30mm is selected as the raw material. Preheat the forging cylinder 5 and the mold 10 to 400°C and 450°C respectively; place the pure aluminum billet at the rear end of the heating device 3, and push the pure aluminum billet into the heating device 3 through the horizontal pushing system 2; After the horizontal pushing system 2 is reset, start the heating equipment 3 to heat the pure aluminum billet; measure the temperature of the surface of the pure aluminum billet through the thermometer 9 and feed back the temperature parameters to the heating device 3, and wait for the pure aluminum billet to be heated. After the surface temperature of the billet reaches 400°C, use the heating device 3 to keep the temperature of the pure aluminum billet constant and keep it warm for 3 minutes; turn off the heating device 3, push the pure aluminum billet out of the heating device 3 through the horizontal pushing system 2 an...
