Stepped rapid blanking precision machining die for steel pipe table

The utility model belongs to the technical field of steel pipe table machining, and particularly relates to a stepped rapid blanking precision machining die for a steel pipe table, which comprises a bottom plate, a frame is welded at the upper end of the bottom plate, a punching machine is fixedly mounted on the frame, a punch is arranged at the lower end of the punching machine, a threaded rod is in threaded connection with the inside of the bottom plate, and the threaded rod is in threaded connection with the bottom plate. A connecting base is rotationally connected to the outer side of the threaded rod, a supporting plate is welded to the connecting base, and a supporting block is welded to the lower end of the supporting plate. The threaded rod is connected into the bottom plate through the threads, the threaded rod is rotated to enable the supporting plate to ascend so that the relative distance between the supporting plate and the bottom plate can be adjusted, then the special-shaped pipe fitting can be
