Summary: | The utility model provides a hydraulic two-step propelling pipe making machine with four cylinders, belonging to the steel pipe processing apparatus and comprising a bracket, a supported plate, a rear push plate, a front push plate, and a front supported plate, arranged on a machine base orderly from rear to front. A hydraulic oil cylinder is fixed on the bracket and the supported plate, and the rear push plate is fixed on the outer end of the plunger of the hydraulic oil cylinder. One end of the push rod is fixed on the rear push plate, and the other end is fixed on the front push plate. The foreside of the machine base is provided with a mould device, and the hydraulic oil cylinder has two groups. Each group has two hydraulic oil cylinders. The pipe making machine can greatly improve the push force propelling the steel pipe forwards for using four hydraulic oil cylinders, so the stability of operation is increased. The utility model utilizes the advantage produced by the hydraulic oil cylinder of the existing hydraulic two-step propelling pipe making machine, completes the reducing aperture and the wall thickness of the steel pipe in the action of the mould device, or processes the circular steel pipe into the square pipe, to decrease the production cost of the steel pipe manufacturing apparatus. |
