The utility model discloses a multistage drive type punching device, punching die and punching machine, including template, multistage cylinder connecting structure, stamping structure and punching needle structure, wherein the primary drive cylinder in multistage cylinder connecting structure is fixed on the mounting surface, the output shaft of the upper drive cylinder is connected with the lower drive cylinder, and the output shaft of the lower drive cylinder is connected with the punching needle structure. An output shaft of the last-stage driving air cylinder is connected with the stamping structure. The multi-stage air cylinder connecting structure drives the punching structure to move back and forth among the multiple punching needles. A multi-stage air cylinder combined driving structure is used for replacing a traditional motor and lead screw matched driving structure, compared with a motor and lead screw matched driving structure, the multi-stage air cylinder combined driving structure is lower in c
