The steel tube throwing prevention device not only can effectively prevent the steel tube from being thrown out, but also requires no adding of lubricating agent for a plurality of times, leads lubrication of a steel tube protection device to last without maintenance, guarantees safe production of seamless steel tubes, and improves production efficiency.
Description
Technical field
The utility model relates to the anti-rejection device of a kind of steel pipe, relates in particular to a kind of seamless steel pipe hot-rolling machine anti-rejection device of steel pipe.
Background technology
The seamless steel pipe hot-rolling machine is made one of capital equipment of seamless steel pipe, round steel becomes seamless steel pipe through hot mill rolling after high-temperature process, but in course of hot rolling, because quality is softer after the round steel high-temperature process, through the hot rolling high speed rotating time, can produce centrifugal force, thereby the easy whipping of round steel at hot-rolling mill dog upstream position, so just may cause the iron filings even the whole round steel of high temperature to throw away, cause great security incident, though the manufacturer of some seamless steel pipe has also taked some to handle and has prevented the steel pipe whipping, fix some anti-rejection devices at the upstream position of dog, but because the temperature of round steel is too high, reach about 1200 °, and the cooling water that uses during hot rolling and the vapours of generation make that these anti-rejection device lubricant effects are very undesirable, often cause easily and lose oil, thereby the destruction of causing anti-rejection device has been reduced production efficiency greatly.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of seamless steel pipe hot-rolling machine anti-rejection device of steel pipe is provided, the anti-rejection device of this steel pipe can prevent effectively that not only steel pipe from throwing away, but also need not repeatedly to add lubricant, make the steel pipe protector lubricated lasting, Maintenance free, guarantee the safety in production of seamless steel pipe, improved production efficiency.
For solving the problems of the technologies described above, the technical solution of the utility model is: the seamless steel pipe hot-rolling machine anti-rejection device of steel pipe, the anti-rejection device of described steel pipe is installed on the dog upstream position of hot-rolling mill, comprise axle sleeve and back shaft, described axle sleeve is sleeved on described back shaft periphery and wraps up described whole back shaft, be fixed with Connection Block on the described axle sleeve outer peripheral face, described axle sleeve outer peripheral face is provided with the installing port that is communicated with inner diameter hole, described installing port circumferentially extends, and described back shaft is fixedlyed connected with the frame of described hot-rolling mill by the connecting rod that passes described installing port; Steel pipe is buckled watt, and described steel pipe is buckled on watt outer peripheral face that is fixed in described axle sleeve, and described steel pipe is buckled the cover portion that buckles that is used to buckle the cover steel pipe that watt is provided with; Drive the power set of described axle sleeve reciprocally swinging, described power set and described Connection Block are hinged.
After having adopted technique scheme, effect of the present utility model is: because the anti-rejection device of described steel pipe comprises axle sleeve and back shaft, described axle sleeve is sleeved on described back shaft periphery and wraps up described whole back shaft, be fixed with Connection Block on the described axle sleeve outer peripheral face, described axle sleeve outer peripheral face is provided with the installing port that is communicated with inner diameter hole, described installing port circumferentially extends, and described back shaft is fixedlyed connected with the frame of described hot-rolling mill by the connecting rod that passes described installing port; Steel pipe is buckled watt, and described steel pipe is buckled on watt outer peripheral face that is fixed in described axle sleeve, and described steel pipe is buckled the cover portion that buckles that is used to buckle the cover steel pipe that watt is provided with; Drive the power set of described axle sleeve reciprocally swinging, described power set and described Connection Block are hinged, therefore when seamless steel pipe hot-rolling, installing port on the axle sleeve outer peripheral face provides the space for the axle sleeve swing, axle sleeve just can drive relative back shaft swing by power set, thereby being buckled, the steel pipe that is fixed on the described axle sleeve watt buckles the steel pipe that covers on the dog upstream position, steel pipe is only buckled a watt lower space whipping at steel pipe in the time of so just can guaranteeing hot rolling, thereby guaranteed safety in production, and whole back shaft all is wrapped in the axle sleeve, so just can put into resistant to elevated temperatures graphite as lubricant from installing port, and graphite loss not at all in axle sleeve, thereby make lastingly lubricated, need not repeatedly to add again lubricant, remove the trouble of safeguarding from, prolonged the service life of the anti-rejection device of steel pipe, improved production efficiency.
