Abstract
A pipe binding device of a thin wall seamless steel pipe hot mill comprises two rollers left and right; a mandril is arranged between the two rollers; each roller comprises a roller body and roller necks at two sides; at least one roller neck closer to an inlet side is connected with an oil cylinder by a pin shaft; the two roller necks farther away from the inlet side are connected with hinging parts. The pipe binding device has the beneficial effects that compared with the prior art, since the roller neck at one side is driven by the oil cylinder, and the roller bodies are away from the mandril, a distance between the two rollers left and right is enlarged, which is equivalent to increase of the wall thickness of the steel pipe (or the outer diameter of the steel pipe is increased), the binding intensity of the rollers and mandril to pipe blanks is reduced, the mutual action force between the mandril, the rollers and the pipe blanks is reduced and accidents are reduced.
Description
Technical field
The present invention relates to a kind of rolling tube equipment of thin-wall seamless steel pipe hot-rolling mill, particularly hot-rolling mill.
Background technology
Present thin-wall seamless steel pipe is generally produced by hot-rolling mill, and hot-rolling mill, by columned pipe and the plug relative motion being arranged on its axial direction, makes pipe from mandrel outer surface by just forming steel pipe, the outer surface of plug and the contact internal walls of steel pipe.In general, do not move at axial direction plug, but pipe is moved to central layer direction by the effect of four rolls.Four rolls are distributed in pipe four direction up and down respectively, can be regulated the external diameter of seamless pipe by the distance adjusted between it.Problem is: because the interaction force of excellent core, roll and pipe is huge, when rolling pipe afterbody, and rolling tail end easily occurs being fried rotten etc. irregularly shaped, the production accident such as simultaneously easily cause brokenly tail, time to drag.
Summary of the invention
For overcoming above-mentioned deficiency, the object of this invention is to provide a kind of rolling tube equipment of safer thin-wall seamless steel pipe hot-rolling mill.
Technical scheme of the present invention is specially:
A kind of rolling tube equipment of thin-wall seamless steel pipe hot-rolling mill, comprise two rolls in left and right, plug is provided with between two rolls, each roll comprises the roll neck of the body of roll and both sides, at least one roll neck nearer apart from entrance side passes through pinned connection oil cylinder, roll neck all connecting hinge fittings that two distance entrance sides are far away.
Two nearer roll necks of distance entrance side all pass through pinned connection oil cylinder.
The side of the body of roll is protruded laterally.
Beneficial effect of the present invention is: compared to the prior art, the present invention by oil cylinder drive this side roll neck and and rod body away from plug, the distance between two rolls in left and right is caused to become large, the wall thickness being equivalent to steel pipe increases (external diameter of steel pipe becomes large in other words), roll, excellent core are reduced pipe rolling tube intensity, so reduce the interaction force of excellent core, roll and pipe, decrease the generation of accident.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
Fig. 2 is the enlarged diagram on the right side of Fig. 1.
Fig. 3 is the enlarged diagram of the body of roll.
Detailed description of the invention
As shown in Figure 1, Figure 2, a kind of rolling tube equipment of thin-wall seamless steel pipe hot-rolling mill, comprise two rolls 2 in left and right, plug 1 is provided with between two rolls 2, each roll 2 comprises the roll neck 22 of the body of roll 21 and both sides, at least one roll neck 22 nearer apart from entrance side passes through pinned connection oil cylinder 3, two distance entrance side roll neck 22 all connecting hinge fittings far away.
Two nearer roll necks 22 of distance entrance side all pass through pinned connection oil cylinder 3.
The side 28 of the body of roll 21 is protruded laterally.
Its operation principle is:
This equipment is contained on hot-rolling mill, makes two rolls be two rolls in horizontal direction.The roll neck far away apart from entrance side is hinged in frame, and oil cylinder is fixed in the frame away from plug side.When just starting, maximum position stretched out by oil cylinder, adjust the gap between two rolls, pipe rolling tube is entered from entrance side, when being rolled down to pipe afterbody, operating cyloinder shrinks, because the roll neck of the other end is hinged fixing, so oil cylinder drive this side roll neck and and rod body away from plug, cause the distance between two rolls in left and right to become large, the wall thickness being equivalent to steel pipe increases (external diameter of steel pipe becomes large in other words), and roll, excellent core are reduced pipe rolling tube intensity, so reduce the interaction force of excellent core, roll and pipe, decrease the generation of accident.
Finally, because the tail end wall thickness of the steel pipe be bundled into is defective, amputated, the same with prior art.
Other guide is shown in prior art.
