Abstract

The invention discloses a punching machine. The punching machine comprises a punching device and a conveying structure which is located under a punching knife of the punching device. The punching device comprises a rack, an oil cylinder, the punching knife and an oil cylinder control device, wherein the oil cylinder is arranged on the rack in an inverted manner, and the punching knife is mounted on the end face of a piston rod of the oil cylinder. The conveying structure comprises a workbench, a conveying device and a locating device, wherein the workbench is located under the punching knife, and the locating device is located on the workbench. The locating device comprises a first photoelectric sensor and a locating control device, wherein the first photoelectric sensor is located on the upper end face of the workbench. A panel is conveyed onto the workbench through the conveying device. According to the punching machine, a second photoelectric sensor detects the moving distance of a moving device, and precision of the moving distance of the moving device is enhanced; and rotating speed of a servo motor is constant, the first photoelectric sensor senses passing of the panel, and the position where the panel is stopped is accurate.
