The invention belongs to the technical field of hard alloy machining and relates to an environment-friendly device for performing no-water extruding on bar-shaped hard alloy blanks. The technical problem needing to be solved is to provide the environment-friendly device for performing no-water extruding on bar-shaped hard alloy blanks. In order to solve the technical problem, the environment-friendly device for performing no-water extruding on bar-shaped hard alloy blanks is provided and comprises a hydraulic cylinder, a piston, an extruding cylinder, a discharging barrel, rollers, motors, a transmission wheel, a discharging high-pressure spray nozzle, a high-pressure tank and an extruding high-pressure spray nozzle. The hydraulic cylinder is connected with the piston. The piston is matched with the extruding cylinder. The discharging barrel is arranged under the extruding cylinder. The rollers are symmetrically arranged on the discharging barrel. The motors are arranged on the two sides of the discharging barrel. The environment-friendly device for performing no-water extruding on bar-shaped hard alloy blanks overcomes the defect that when existing bar-shaped hard alloy materials are extruded, water is needed for lubrication. When the environment-friendly device for performing no-water extruding on bar-shaped hard alloy blanks is used for extruding the bar-shaped hard alloy blanks, water is not needed for lubrication, and water resources are saved.
