A method for using a processing and punching device for a radiator core main sheet, based on the processing and punching device for a radiator core main sheet according to claim 9, characterized in that: The following steps are involved: S1: One end of the raw material used for producing the main plate of the radiator core is passed through the fixed frame (10) and extended into the side shell (6). At this time, the side walls of the raw material are inserted between the symmetrically arranged material limiting components (9). The raw material presses the groove wheels (15) on both sides to move away from each other. Under the elastic force of the first spring (17), the side plate (16) tends to approach the side shell (6), and drives the groove wheel (15) to press the raw material through the movable rod (14), thereby achieving limiting and flexible clamping of the raw material plate, which is convenient for stable transportation of the raw material; S2: The operator rotates and adjusts the rotating wheels (24) on both sides of the fixed frame (10), the rotating wheels (24) drive the threaded rod (23) to rotate, the threaded rod (23) drives the vertical plate (19) to move, and the vertical plate (19) drives the horizontal plate (18) to move toward the feeding channel side of the fixed frame (10), so that the conveying wheels (22) on both sides can clamp the raw materials for production; S3: The hydraulic cylinder (2) is started to pull the top plate (3) to move, and the top plate (3) pushes the stamping die (5) through the connecting plate (4), so that the stamping die (5) moves to the inner cavity of the side shell (6). The plurality of stamping dies (5) can be used to simultaneously perform multi-station stamping operations on the main sheet of the radiator core, and the waste material after the stamping process enters the discharge trough (8) under the push of the stamping die (5), and is transported to a designated position through the action of the discharge shell (34); S4: After the stamping die (5) completes the stamping process on the raw material, the hydraulic cylinder (2) is controlled to move in the reverse direction, the hydraulic cylinder (2) pushes the top plate (3) to move upward, and the top plate (3) pulls the stamping die (5) to reset through the connecting plate (4). At the same time, the motor (20) is started to drive the rotating shaft (21) to rotate, and the rotating shaft (21) drives the conveying wheel (22) to rotate, and the raw material is conveyed through the conveying wheels (22) on both sides, so that a section of the radiator core main sheet that has been stamped passes through the feeding trough (7); S5: When the hydraulic cylinder (2) drives the top plate (3) to rise to the highest position, the top plate (3) drives the movable plate (27) to rise to the highest position, the driving plate (2701) pushes the fixed plate (28), the fixed plate (28) drives the connecting rod (29) to move, the second spring (31) is compressed and the cutter (30) cuts the stamped radiator core main sheet material, thus completing the stamping and cutting processing operations of a single radiator core main sheet; S6: By continuously repeating the above steps S3-S5, efficient and convenient stamping processing operations on the main plate of the radiator core are achieved.
