Summary:The invention relates to the mechanical equipment technology field, in particular to a punching machine. The punching machine comprises a drive gear and a driven gear, wherein the drive gear is connected with a motor rotation shaft through a transmission device, the driven gear is fixed on a crankshaft, the drive gear transmits power through meshing with the driven gear, a work surface of gear teeth on the drive gear is in an arc shape, an arc-shaped groove is formed in the driven gear, and the inner surface of the groove is in tight fit with the outer surfaces of the gear teeth when the groove is meshed with the gear teeth. According to the punching machine, the driven gear and the drive gear are meshed with each other through arc-shaped planes from beginning to end, and compared with line contact of an existing gear, the drive gear and the driven gear are subject to even stress, a tooth breaking probability is greatly reduced, and reinforcing steel bars are pre-buried in the machineframe in the stress direc
