Abstract
The utility model provides a bundle pipe equipment of thin wall seamless steel pipe hot rolling mill, is equipped with the plug including controlling two rolls between two rolls, and every roll includes the roll neck of the body of roll and both sides, and at least one roll neck nearer apart from the entrance side is through selling the hub connection hydro -cylinder, and the articulated elements is all connected to two roll necks far away apart from the entrance side. The beneficial effects of the utility model are that: compared with the prior art, the utility model discloses a hydro -cylinder drive this side the roll neck and the rod body keeps away from the plug, about resulting in between two rolls apart from the grow, be equivalent to that the wall thickness of steel pipe increases (perhaps saying the external diameter grow of steel pipe), make roll, excellent core prick the pipe strength reduction to the pipe, so reduced the interact of excellent core, roll and pipe and do all can, reduced the emergence of accident.
Description
Technical field
This utility model relates to the rolling tube equipment of a kind of thin-wall seamless steel pipe hot-rolling mill, particularly hot-rolling mill.
Background technology
Present thin-wall seamless steel pipe is usually and is 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 respectively distributed to pipe four direction up and down, can be regulated the external diameter of seamless pipe by the distance adjusted between.Problem is: because the interaction force of rod 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 drag.
Utility model content
For overcoming above-mentioned deficiency, the purpose of this utility model is to provide the rolling tube equipment of a kind of safer thin-wall seamless steel pipe hot-rolling mill.
The technical solution of the utility model particularly as follows:
A kind of rolling tube equipment of thin-wall seamless steel pipe hot-rolling mill, including two rolls in left and right, it is provided with plug between two rolls, each roll includes the roll neck of the body of roll and both sides, at least one connects oil cylinder apart from the roll neck that entrance side is nearer by bearing pin, two distance entrance side all connecting hinge fittings of roll neck farther out.
Two all connect oil cylinder by bearing pin apart from the roll neck that entrance side is nearer.
The side of the body of roll is protruded laterally.
The beneficial effects of the utility model are: compared to the prior art, this utility model by oil cylinder drive this side roll neck and and rod body away from plug, cause that the distance between two rolls in left and right becomes big, the wall thickness being equivalent to steel pipe increases (external diameter of steel pipe becomes big in other words), make roll, rod core that pipe rolling tube intensity to be reduced, so reducing the interaction force of rod core, roll and pipe, decrease the generation of accident.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
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, including two rolls 2 in left and right, plug 1 it is provided with between two rolls 2, each roll 2 includes the roll neck 22 of the body of roll 21 and both sides, at least one connects oil cylinder 3 apart from the roll neck 22 that entrance side is nearer by bearing pin, two distance entrance side roll neck 22 all connecting hinge fittings farther out.
Two are all passed through bearing pin apart from the roll neck 22 that entrance side is nearer and connect oil cylinder 3.
The side 28 of the body of roll 21 is protruded laterally.
Its operation principle is:
Being contained on hot-rolling mill by this equipment, making two rolls is two rolls in horizontal direction.Distance entrance side roll neck farther out is hinged in frame, in the fixing frame away from plug side of oil cylinder.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, causing that the distance between two rolls in left and right becomes big, the wall thickness being equivalent to steel pipe increases (external diameter of steel pipe becomes big in other words), makes roll, rod core that pipe rolling tube intensity to be reduced, so reducing the interaction force of rod core, roll and pipe, decrease the generation of accident.
Finally, because the tail end wall thickness of the steel pipe being bundled into is defective, amputated, the same with prior art.
Other guide is shown in prior art.
