The invention relates to the technical field of manufacturing of punching machinery, in particular to a simple dual-drive punching machine mainly comprising a support base, a frame, two drive mechanisms, a punching head and a die base. The frame is fixed on the support base. The drive mechanisms are symmetrically disposed on left and right sides of the frame. Each drive mechanism comprises a flywheel, a reducer and an eccentric wheel; the flywheel is disposed outside the frame; a rotating shaft of the flywheel extends into the frame; the reducer is disposed at the rear of the frame; the reducer is connected with the eccentric wheel through a belt; the eccentric wheel is disposed inside the frame and connected with the rotating shaft. A clamping block is disposed between the eccentric wheels; a punching shaft vertically arranged is connected to the clamping block; the punching head is mounted on the punching shaft; the die base is disposed on the frame right below the punching head. The simple dual-drive punching machine is simple in structure; the two drive mechanisms are used to control the punching machine to operate at the same time; punching precision of punched pieces is improved; product quality is improved; adjustment is flexible and convenient; the simple dual-drive punching machine is convenient to popularize and apply.
