Abstract
The utility model relates to a forming machine for hot rolling and rolling online forming of a seamless special pipe. The forming machine is characterized by comprising a rack (1), wherein a row of forming roller groups (2) are arranged on the rack (1); a feeding roller rack (3) is arranged on the front side of the forming roller groups (2); a motor (4) is arranged on the rear side of the forming roller group (2); the motor (4) is connected with a speed reducer (6) through a coupler (5); the output shaft of the speed reducer (6) is connected with a transmission shaft (7) above the rack (1); meanwhile, a cooling water pipe (8) which is arranged front and back is arranged below the rack (1); the cooling water pipe (8) is connected with a plurality of hoses (9); each hose (9) is arranged near a bearing of the transmission shaft (7); a water outlet of each hose (9) is aligned at the bearing. By adopting the forming machine for hot rolling and rolling online forming of the seamless special pipe, the forming roller can be prevented from being affected by high temperature, normal transmission is ensured, and suspended production is not caused.
Description
Technical field
The utility model relates to be shaped the online forming machine of seamless heterotype pipe of a kind of hot rolling, roll-in, and it can form technique to high temperature seamless heterotype pipe.
Background technology
At present, seamless heterotype steel pipe adopts cold-drawing technology processing mostly, but cold-drawn processing technology is comparatively complicated, needs the operations such as system head, annealing, pickling, cold-drawn, aligning, and cold-drawn is sliding friction, required Drawing Force is larger, easily pulls the surfaces externally and internally of steel pipe, and not only energy consumption is high for the manufacture method of cold-drawn simultaneously, recovery rate of iron is low, and acid washing phosphorization etc. also can bring environmental pollution, therefore, need to carry out the online processing technology being shaped of high temperature to seamless heterotype pipe.
But current forming machine only forms technique to the seamless heterotype pipe of low temperature, the seamless heterotype pipe of high temperature can damage forming rolls, and drive bearing on forming machine also can be affected, and causes transmission position to be broken down, and causes to produce and suspends.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and guarantees that forming rolls is not subject to temperatures involved, has guaranteed that transmission normally carries out, and can not make to produce be shaped the online forming machine of seamless heterotype pipe of the hot rolling, the roll-in that suspend.
The purpose of this utility model is achieved in that
Be shaped the online forming machine of seamless heterotype pipe of the utility model hot rolling, roll-in, comprises frame, and described frame is provided with row's forming rolls group, and this forming rolls group is by multiple forming rolls module compositions;
The front side of described forming rolls group is provided with feeding roller frame, and the rear side of described forming rolls group is provided with motor, and described motor is connected with reductor by shaft coupling, and the output of described reductor is connected with the power transmission shaft of frame top;
The cooling water pipe that simultaneously below of frame is arranged before and after being provided with one, is connected to multiple flexible pipes on described cooling water pipe, and every flexible pipe is all located at the bearing side of power transmission shaft, the delivery port alignment bearings of flexible pipe.
The rear side of described frame is also equipped with adjusting head.
Forming rolls in described forming rolls group adopts refractory steel H13.
This hot rolling, the roll-in forming machine of seamless heterotype pipe that is shaped online has the following advantages compared with technology in the past:
This hot rolling, roll-in are shaped the forming machine of seamless heterotype pipe online by forming rolls is transformed, guarantee the calorific intensity of forming rolls, make it not be subject to temperatures involved, the bearing of power transmission shaft is high temperature resistant bearing simultaneously, and be furnished with cooling device it is lowered the temperature, prevent that the seamless heterotype pipe range time from will cause transmission fault after heat transmission, thereby guaranteed to produce unaffected.
