referring to fig. 1-5, in the present embodiment, in the production application, the sheet material 1001 to be blanked is only laid on the cutting board 6, and the typeset processing pattern data is input into the controller 8, so that the present invention enters the automatic operation state. Under the control of the controller 8, the initial state of the present embodiment is: the piston rod of the ram cylinder 7 lifts the swivel head 1 upwards to the highest point. After the machining operation is started, the X-axis driving module 4 drives the X-axis heavy-load sliding block 46 to carry the punching oil cylinder 7 to a preset position in the X-axis direction, the Y-axis driving module 5 drives the Y-axis heavy-load sliding block 56 to carry the cutting board 6 to a preset position in the Y-axis direction, meanwhile, the R-axis driving motor 14 on the rotating head 1 rotates the punch 2 to a preset position through the connecting seat 21, and the punch 2 performs tool changing action at the current position: the swing cylinder 27 drives the swing chuck 28 to rotate clockwise to make the arm rod of the swing chuck 28 separate from the mortise of the telescopic rod 26, except the preset cutting die assembly 29 of the current station, the telescopic cylinders 25 corresponding to the other cutting die assemblies 29 drive the telescopic rods 26 thereof to lift and retract the cutting die assemblies, the telescopic cylinders 25 corresponding to the preset cutting die assembly 29 of the current station drive the corresponding telescopic rods 26 to extend and eject the cutting die assembly, then the swing cylinder 27 drives the swing chuck 28 to rotate anticlockwise to make the arm rod of the swing chuck 28 re-clamped into the mortise of the telescopic rod 26, at this time, the cutting die assembly 29 is aligned with the preset position of the sheet material 1001 to be blanked on the cutting board 6, then the piston rod of the punching cylinder 7 moves downwards until the cutting die at the lower end of the cutting die assembly 29 punches the sheet material to be blanked and blanks to be blanked, therefore, a huge punching force is not applied to the piston rod of the telescopic cylinder 25 corresponding to the lower cutting die assembly 29 in the punching process, but rather on the telescoping rod 26 associated with the cutting die assembly 29, the telescoping cylinder 25 can be of a light duty design and have a longer service life and lower design and service maintenance costs. After the punching action is finished, the piston rod of the punching oil cylinder 7 lifts the rotating head 1 and the punch 2 upwards to the highest point again to prepare for the punching action of the next station. The above-described blanking-tool changing-blanking operation is repeated until the blanking process of the full-plate to-be-blanked sheet material 1001 is finished. In the embodiment, the telescopic transposition of the plurality of cutting dies is realized by means of the telescopic rods with the mortises and driven by the group of telescopic oil cylinders, and the punching force borne by the working cutting dies is borne by the rotary swing chuck and the bracket columns with the mortises and driven by the rotary swing oil cylinders, so that the structure and the size of the multi-cutting-die punch assembly are simplified.
