The working principle and the using process of the invention are as follows: the blank is placed in the lower die 3, then the upper die column 6 is controlled by the controller 17, so that the upper die column 6 drives the upper die 4 to forge the blank, the blank is forced to deform and flow and is quickly filled in a cavity formed by the upper die 4 and the lower die 3, a hub forging is obtained, then the water cooler 16 is started by the controller 17, so that the water cooler 16 conveys cooling liquid into the water tank 8, then the water pump 9 is started by the controller 17, at the moment, the cooling liquid in the water tank 8 is conveyed into the cooling pipe 21 on the inner side wall of the die base 2 by the water pump 9, so that the forging is cooled, the temperature of the forging is better due to the spiral disc shape of the cooling pipe 21, the working efficiency of the forging is improved, then the cooling liquid is conveyed into the drain pipe 10 from the cooling pipe 21, at the moment, the temperature sensor 11 in the drain pipe 10 detects the cooling inside of the drain pipe 10, and the signal is transmitted to the controller 17, if the temperature signal reaches the set value, the controller 17 opens the first electric control valve 13, closes the second electric control valve 15, at the moment, the cooling liquid is transmitted to the water cooling machine 16 through the first branch pipe 12, so as to cool the cooling liquid, when the temperature signal is lower than the set value, the controller 17 opens the second electric control valve 15, closes the first electric control valve 13, at the moment, the cooling liquid is transmitted to the inside of the water tank 8 through the second branch pipe 14, so that the cooling liquid continuously participates in the heat dissipation of the forging, then the controller 17 opens the hydraulic cylinder 37, so that the hydraulic cylinder 37 drives the push block 35, at the moment, the push block 35 pushes the slide bar 34 to move upwards, so as to drive the push block 32 to move upwards, further push the forging out of the lower die 3, so as to facilitate the forging taking out, after the push-out is completed, the controller 17 controls the hydraulic cylinder 37 to drive the pushing block 35 to move downwards, so as to drive the ejecting block 32 to return to the ejecting groove 31, thereby facilitating the next forging, when the upper die 4 needs to be repaired or replaced, the electromagnet 71 is closed through the controller 17, and the locking block 7 moves upwards under the action of the elastic force of the compression spring 52, so that the limiting post 72 is far away from the fixing hole 42, and then the mounting block 5 is driven to rotate by rotating the upper die upright post 6, thereby taking the mounting block 5 out of the mounting hole 41, then mounting the intact upper mold 4 on the mounting block 5 through the mounting hole 41 by screwing, finally opening the electromagnet 71 through the controller 17, therefore, the fixed locking block 7 adsorbs the top of the belt mounting block 5 under the magnetic force of the electromagnet 71, and the limiting column 72 is inserted into the fixing hole 42, so that the stability of the upper die 4 and the mounting block 5 is improved.
