The invention relates to a hardware workpiece punching device capable of automatically pushing materials. The device comprises a base, a support rod, a cross rod, an operation table, a raw material box, a punching mechanism and a material pushing mechanism, wherein the hardware workpiece punching device capable of automatically pushing the materials realizes continuous punching of a workpiece through the punching mechanism, and realizes automatic intermittent material pushing of the workpiece through the material pushing mechanism, compared with an existing punching device, through linkage of the material pushing mechanism and the punching mechanism, the device achieves online material pushing and punching of the workpiece, efficiency is improved, a pure mechanical mechanism is adopted for linkage, use of electronic elements such as a sensor is avoided, stability of the device is improved, the service life of the device is prolonged, meanwhile, operation of the punching mechanism and the material pushing mechanism is achieved through one output end, energy is saved, compared with an existing material pushing mechanism, movement of rolling wheels is limited, damped and lubricated through a rolling unit, a buffering unit and a lubricating unit, a push rod moves more stably, and the better material pushing effect is achieved.
