Automatic punching machine and method for transformer accessory conductive copper bar

The transformer an automatic punching machine for a transformer accessory conductive copper bar. The machine comprises a base, a supporting frame, clamping frames, pushing devices, a punching device and a material collecting box, wherein the supporting frame is fixedly installed in the middle of the upper surface of the base, the clamping frames are slidably installed on the two sides of an inner cavity of the supporting frame, the pushing devices connected with the supporting frame are arranged below the clamping frames on the two sides, the punching device is fixedly installed on the rear side of the upper surface of the base, and the material collecting box is placed on the rear side of the upper surface of the base. The invention may solve the problems that when an existing conductive copper bar is punched, automatic feeding of the copper bar cannot be achieved, so that machining of the copper bar is time-consuming and labor-consuming; the distance of a to-be-punched hole in the copper bar cannot be adjus
