When the secondary hydraulic mechanism (35) is in a return state, the first-stage support spring (24), the second-stage support spring (27), the third-stage support spring (32), and the fourth-stage support spring (33) are all in a reset state, and at this time, the lower surface of the corner cutter head (18) is higher than the lower side surface of the air avoidance groove (28).

6. The continuous stamping and forming equipment for a big data chassis server according to claim 5, characterized in that: A guide pulley groove (36) is provided on the side wall of the guide seat (20), a guide pulley mounting groove is provided on the inner side wall of the guide ring (29), a guide pulley (37) is rotatably mounted in the guide pulley mounting groove, and the guide pulley (37) is rollingly arranged in the guide pulley groove (36).

7. A continuous stamping process for a big data chassis server, characterized in that: The continuous stamping process of the big data chassis server is processed by any one of the continuous stamping equipment of the big data chassis server of claims 3-6 above. The punching hole (2) on the chassis shell (1) of the big data chassis server is first moved by the secondary hydraulic mechanism (35) to make the lower end surfaces of the main cutter head (17), the corner cutter head (18), and the side cutter head (19) flush with each other, and then the main hydraulic mechanism is driven to press down, thereby driving the cutter head (8) to complete the stamping of the punching hole (2). Then the secondary hydraulic mechanism (35) returns, so that the corner cutter head (18) and the side cutter head (19) are retracted for a distance, so that the corner cutter head (18) and the side cutter head (19) are retracted for a distance inward, so that a certain gap is formed between the corner cutter head (18) and the side cutter head (19) and the side of the punching hole (2), so as to avoid friction damage to the punching hole (2) when the cutter head (8) is reset, and finally the main hydraulic mechanism returns.
