[0015] (1) Heating: First, the raw material - the metal billet is fed into the heating assembly, which includes a supporting cabinet with a medium frequency heating furnace on the top. The medium frequency heating furnace quickly heats the metal billet to the required forging temperature through the principle of electromagnetic induction. The heating temperature is between 1130-1200°C. The heated metal billet is discharged from the discharge port and smoothly transported to the rolling machine through the discharge chute;

[0016] (2) Forging: The heated metal blank enters the rolling forging machine, which is composed of two support seats. Two upper and lower movable rollers are installed between the inner walls. The movable rollers rotate under the drive of the second drive motor to roll and stretch the metal blank, so that it gradually forms a blank close to the final shape;

[0017] (3) Positioning and conveying: The forged blank is conveyed to the transfer box for temporary storage through the positioning conveyor line.

The punch press consists of a second main frame, a first drive motor, a guide arm, a punch block, a punch table and a die mouth. The first drive motor drives the guide arm and the punch block to move downward, and the die mouth is used to stamp the blank to form the specific contour and detail features of the automobile outer wheel.

[0020] (6) Trimming: After stamping, the workpiece needs to be trimmed to remove excess material. The push cylinder pushes the workpiece along the edge material slideway, while the trimming device cuts off the excess part and collects the waste into the trimming material box.

[0021] (7) Lathe finishing: After trimming, the workpiece enters the lathe for final precision machining. The lathe consists of an overhead frame, a base plate, a fixed seat, a third drive motor, a workpiece fixing fixture, a linear slide, a transmission rod, a screw and a handwheel. The third drive motor drives the workpiece fixing fixture to rotate, and at the same time, the transmission rod drives the screw to rotate, so that the slide moves along the linear slide. A mounting seat and a turning tool are provided above the slide to cut the workpiece to ensure that its dimensional accuracy and surface finish meet the design requirements.

[0022] (8) Safety and control: During the entire processing process, the safety fence provides protection for the operator to prevent accidental injuries.

The medium frequency heating furnace (10) rapidly heats the metal billet to the temperature required for forging by electromagnetic induction principle. The heating temperature is between 1130-1200°C. The heated metal billet is discharged from a discharge port (14) and smoothly transported to a rolling forging machine (12) through a discharge chute (11); (2) Forging: The heated metal blank enters a rolling forging machine (12). The rolling forging machine (12) is composed of two support seats (20). Two upper and lower movable rollers (19) are installed between the inner walls. The movable rollers (19) rotate under the drive of a second driving motor (21) to roll and stretch the metal blank, so that the blank is gradually formed into a blank close to the final shape. (3) Positioning and conveying: The forged blank is conveyed to the transfer box for temporary storage via the positioning conveyor line (8). The positioning conveyor line (8) ensures that the blank enters the next process accurately. Subsequently, the first robot (2) and the second robot (13) take the blank out of the transfer box and place it accurately on the workbench of the electric screw press (1); (4) Press processing: On the electric screw press (1), the hydraulic pump (30) drives the hydraulic cylinder (31) to work, so that the hydraulic rod (32) moves downward, exerting a huge pressure on the blank. The positioning fixture (34) above the workbench ensures that the blank remains stable during the processing. (5) Stamping: The blank after pressure processing is transported to the punching machine (3) for fine processing. The punching machine (3) is composed of a second main frame (23), a first drive motor (22), a guide arm (45), a punching block (46), a punching table (27) and a die opening (28). The first drive motor (22) drives the guide arm (45) and the punching block (46) to move downward, and the die opening (28) is used to punch the blank to form a specific outline and detailed features of the automobile outer wheel. (6) Trimming: After punching, the workpiece needs to be trimmed to remove excess material. The push cylinder (24) pushes the workpiece along the edge material slideway (25), while the trimming device cuts off the excess part and collects the waste material into the trimming material box (47). (7) Lathe (15) finishing: the workpiece after trimming enters the lathe (15) for final precision machining. The lathe (15) is composed of an overhead frame, a bottom plate, a fixed seat (36), a third drive motor (35), a workpiece fixing fixture (37), a linear slide rail (42), a transmission rod (43), a screw rod and a hand wheel (41). The third drive motor (35) drives the workpiece fixing fixture (37) to rotate, and at the same time, the transmission rod (43) drives the screw rod to rotate, so that the slide (40) moves along the linear slide rail (42). A mounting seat (39) and a turning tool (38) are provided above the slide (40) to perform cutting processing on the workpiece to ensure that its dimensional accuracy and surface finish meet the design requirements. (8) Safety and control: During the entire processing process, the safety fence (5) provides protection for the operator to prevent accidental injuries. The power supply box (6) and the main control box (7) provide a stable power supply and precise control signals for the entire system to ensure the normal operation and coordinated work of each device.
