Abstract
The utility model discloses a hydraulic cold bending machine. A bent pipe pressure head is arranged on a swing arm; one end of the bent pipe pressure head is connected with a hydraulic system A, and the other end of the bent pipe pressure head is connected with a molding die; a pipe cutter is arranged on the molding die; a combined chain wheel and a hydraulic system B are arranged below the molding die; the outer side of the molding die is provided with a driven outer die; the driven outer die is provided with a hydraulic system C and an adjustable-pressure roller group; a tensile force return device is connected with a driven outer die line; a rib joint liner is sleeved in the driven outer die, and is connected with a connecting rod; and the connecting rod is connected with a hydraulic system D. The hydraulic cold bending machine has the advantages that: a steel pipe is bent by adopting a cold bending technology and is cut off while bending, so that reasonable utilization of a material is ensured, and waste is avoided; and a cold bending technology is adopted, so that forging is not required, polluted gas is not produced, and the hydraulic cold bending machine is very environmentally-friendly.
Description
Technical field
The utility model relates to a kind of steel pipe bending cutting equipment, and concrete is a kind of hydraulic pressure forming mill.
Background technology
At present, when enterprise is used to drag the bend pipe on the pump in production, all be the hot bending technology that adopts.That is, earlier straight tube tube material is cut into pieces, and then sends into and calcine in the reverberatory furnace, take out after calcining is good and carry out bending again, material after the cooling that the two ends of bend pipe are unnecessary cuts.But when adopting the calcining of this method, coal combustion can produce a large amount of gas that pollution is arranged, serious pollution air, and cut a material that falls and slatterned completely, increased the production cost of enterprise.
The utility model content
To the problem of above-mentioned existence, the purpose of the utility model provides a kind of hydraulic pressure forming mill.
The technical scheme of the utility model is: the hydraulic pressure forming mill, comprise spiral arm, bend pipe pressure head, hydraulic system A, shaping mould, casing knife, composite sprocket, hydraulic system B, passive external mold, hydraulic system C, adjustable pressure roller set, pulling force returning device, ridge joint formula liner, connecting rod, hydraulic system D, and it is characterized in that; The bend pipe pressure head is installed on the spiral arm, and bend pipe pressure head one end is connected with hydraulic system A, and the other end is connected with shaping mould; Casing knife is installed on the shaping mould; The below of shaping mould is provided with composite sprocket and hydraulic system B, and the outside of shaping mould is provided with passive external mold, and passive external mold is provided with hydraulic system C and adjustable pressure roller set; The pulling force returning device is connected with passive outer loft; Be with ridge joint formula liner in the passive external mold, ridge joint formula liner links to each other with connecting rod, and connecting rod is connected with hydraulic system D.
The advantage of the utility model: this equipment adopts the clod wash technology that steel pipe is carried out bending, on one side block an Edge Bend time, has guaranteed the reasonable utilization of material, has avoided waste; Owing to be to adopt the clod wash technology, so need not calcine, so just can not produce the gas of pollution, environmental protection very.
Description of drawings
