The invention discloses a recycled metal resource shearing machine for accelerating the speed of smelting and returning to the furnace. A hydraulic cylinder is hinged at the end, a shearing knife is hinged at the lower end of the hydraulic cylinder, a clamping device is fixedly connected to the upper end of the workbench, a baffle device is fixedly connected to the bottom of the side of the base, and the clamping device includes Bracket, support plate, support seat, worm screw, limit ring, worm gear, first threaded rod, first card seat, pressure rod and roller. This kind of recycled metal resource shearing machine effectively fixes the required metal materials, which is convenient for the shearing knife to cut, avoiding multiple cuttings; the baffle device can adjust the distance between the baffle plate and the shearing knife, and can effectively control Cutting the length of the metal avoids multiple operations and reduces the labor intensity of workers.
