7. The forging die for electric power fitting as recited in claim 1, wherein: the number of the rotating shafts (11), the rollers (12) and the driven gears (13) is multiple, and the outer surfaces of the driven gears (13) are in meshed connection through a transmission toothed belt.

8. The forging die for electric power fitting as recited in claim 1, wherein: the discharging assembly (21) comprises a fixed box (211) fixedly connected inside a lower die (1), a sealing plate (212) is connected to the inside of the fixed box (211) in a sliding manner, a second spring (213) is movably mounted inside the fixed box (211), a connecting rod (214) is fixedly connected to the surface of the sealing plate (212) away from the second spring (213), a venting groove (2141) is formed in the surface of the connecting rod (214), a supporting block (2142) is fixedly connected to the surface of the connecting rod (214) away from the sealing plate (212), the outer surface of the supporting block (2142) is connected to the inside of a material receiving cavity (17) in a sliding manner, and a venting hole (216) communicated with the inside of the fixed box (211) is formed in the surface of the fixed box (211) away from the supporting block (2142).

9. The forging die for electric power fitting as recited in claim 8, wherein: the outer surface of the pressing plate (19) is slidably connected to the inside of the material receiving cavity (17), and an air leakage groove (2141) is formed in the surface of the connecting rod (214).

10. The forging method of the forging die for the electric power fitting is characterized by comprising the following steps of:

s1: when the die is used, a material is placed at the center of the surface of the die cavity seat (612), the stamping head (3) is driven to move downwards through the upper die (2), the material in the die cavity seat (612) is subjected to forging and pressing, after forging and pressing, the servo motor (7) drives the rotating seat (61) to turn over by one hundred eighty degrees through the fixed shaft (8), and at the moment, the material in the die cavity seat (612) after being molded can automatically fall on the surface of the roller (12);

s2: on the basis of S1, through the rotation of the roller (12), the formed material is conveyed out from one end of the discharging cavity (10), and meanwhile, the die cavity seat (612) and residues on the surface of the formed material fall into the material receiving cavity (17) through the surface of the roller (12) for collection;

s3: on the basis of S1, in the overturning process of the rotating seat (61), the first air cylinder (64) drives the adjusting plate (63) to slide in the direction close to the connecting pipe (66) and pressurizes the inside of the sliding groove (68), the inserted rod (610) is driven by the pressure to slide towards the inner wall of the rotating cavity (4) through the sliding block (69), when the air pressure in the sliding groove (68) reaches a certain value, the surface of the steel ball (6102) is in rolling connection with the inner wall of the rotating cavity (4), when the steel ball (6102) rolls to the clamping hole position, the inserted rod (610) is inserted into the jack due to the air pressure in the sliding groove (68), at the moment, the rotating seat (61) just overturns for one hundred eighty degrees, the servo motor (7) is closed, the rotating seat (61) is fixed, and the next material can be forged;

s4: on the basis of S2, after the residue scraps fall inside the material receiving cavity (17), the second cylinder (18) is started, the second cylinder (18) drives the pressing plate (19) to slide, scraps inside the material receiving cavity (17) are punched between the pressing plate (19) and the abutting block (2142), and scraps are punched and formed.
