Abstract
The invention belongs to the field of hot roll equipment for seamless steel tubes, relates to a centering device for steel tube rolling and solves the technical problem that the prior device fails to position hollow billets resulting in the oscillation of core rods and capillary tubes during the rolling process. The inventive device comprises a frame (1), centering rollers and a driving unit. The driving unit consists of a travel-adjustable hydraulic cylinder (2), a swinging arm (5) and driving gears. The driving gears are respectively arranged on rotating shafts on the frame. The rotating shafts are also provided thereon with the centering rollers. The piston rod of the travel-adjustable hydraulic cylinder (2) moves to swing the swinging arm (5) and simultaneously rotate the driving gears, so that centering rollers A (7), C (15) and D (17) are directionally guided or retained relative to a round work piece with the center line of the frame as axis at a certain angle. The centering device is used together with a special horizontal displacement mechanism to achieve the operation of moving work pieces in or out of the center line thereof at the same time, thereby increasing production efficiency.
Description
Technical field
The present invention relates to a kind of seamless steel pipe hot-rolling equipment, particularly a kind of centring means of seamless steel pipe oblique milling
Background technology
At present, when rolling seamless steel pipe, be that plug is penetrated hollow billet, send in the milling train again and be rolled; Rolling mode mainly is divided into full floating mode and restraint mode.The main feature of complete floating mode is that plug floats, enter milling train outlet platform together with hollow forging, take off the circulation of plugs such as rod, cooling again, its advantage is that rolling rhythm is very fast, many plugs recycle, and the plug wearing and tearing are less, and shortcoming is that the equipment complexity is huge, the investment of equipment and factory building is big, the Operation and Maintenance difficulty.The main feature of restraint mode is the plug restraint, does not enter milling train outlet platform together with hollow forging, return back to raw bits after having rolled, and a plug uses repeatedly, and the advantage of this mode is that equipment volume is little, and the investment of equipment factory building is little, and shortcoming is that rolling rhythm is slow.On this basis, the part milling train has used the restraint rolling mode of plug partial circulating, basically this two kinds of rolling advantages have been absorbed, but device structure is unreasonable, cause apparatus function poor, in the operation of rolling, can not effectively locate, cause plug and hollow billet in the operation of rolling, to shake, influence the rolling quality of hollow billet hollow forging.
Summary of the invention
The centring means that the invention solves existing rolled steel tube can not effectively be located hollow forging, cause plug and hollow billet in the operation of rolling, to shake, the rolling quality and the low technical problem of rolling efficiency of hollow billet have been influenced, a kind of centring means of rolled steel tube is provided, has made the investment of equipment and factory building little easy to maintenance.
The present invention is achieved by following scheme:
A kind of centring means of rolled steel tube comprises frame 1, centering roller and drive unit, and described drive unit is made up of the adjustable hydraulic cylinder 2 of stroke, swing arm 5, driven wheel; The cylinder body of the hydraulic cylinder 2 that stroke is adjustable is fixedly installed on the frame 1, the piston rod of the hydraulic cylinder 2 that stroke is adjustable is hinged with an end of swing arm 5 by first connector 4 and second connector 6, swing arm 5 can rotate around it an A9 and rotate, turning cylinder A9 and swing arm 5 link together by turning cylinder first keeper 10, the other end of swing arm 5 is provided with connecting axle 8, and connecting axle 8 is provided with centering roller A7; Turning cylinder A9 links together with driven wheel A12 by second keeper 11, axle B20, turning cylinder C18, turning cylinder D19 are separately positioned on the corresponding bearing of frame 1, the end of axle B20 is set with mesomerism gear 13, the end of turning cylinder C18 is provided with driven wheel C14, and the end of turning cylinder D19 is provided with driven wheel D16; Mesh with the side of driven wheel D16 and a side of mesomerism gear 13 respectively the both sides of driven wheel A12, the opposite side of mesomerism gear 13 and driven wheel C14 engagement; Turning cylinder C18 is provided with the leverage 21 of centering roller C15, is set with centering roller C15 on the leverage 21, also is provided with leverage on the turning cylinder D19, is set with centering roller D17 on this leverage; The motion of the piston rod of the hydraulic cylinder 2 that stroke is adjustable drives swing arm 5 swings simultaneously and driven wheel A12 rotates, driven wheel A12 drives driven wheel D16 and mesomerism gear 13 again and driven wheel C14 rotates, thus realize centering roller A7, centering roller C15 and centering roller D17 with certain angle direction to the frame central line being the positioning and guiding or the clamping of the round piece 22 or the plug 23 of axis.
The cylinder body of the hydraulic cylinder 2 that described stroke is adjustable is fixedly installed on the frame 1 by hydraulic cylinder bearing 3.
The invention has the beneficial effects as follows the center line of in the operation of rolling of steel pipe, accurately locating workpiece, efficiently solve the whipping problem of workpiece, cooperate the operation that has realized specific workpiece is moved into simultaneously, shifts out work centre line with supporting translation mechanism, improved production efficiency, reduced investment outlay.

The specific embodiment
Frame 1 is provided with stroke adjustable hydraulic cylinder 2 and gear A, B, C, four driven wheels of D.The end swing that the piston of the hydraulic cylinder 2 that stroke is adjustable promotes swing arm 5 makes swing arm 5 rotate around turning cylinder A9.The other end of swing arm 5 drives upwards swing of centering roller A7 fixed thereon, arrive working position, the gear A 12 that is fixed on simultaneously on the turning cylinder A9 is rotated, and rotates thereby drive with its meshed gears B13 and gear D 16, and gear B 13 drives with its meshed gears C14 and rotates.Gear C 14 drives centering roller C15 fixed thereon and arrives working position, and in like manner, gear D 16 drives centering roller D17 fixed thereon and arrives working position.Realization is to the centering pilot or the clamping of round piece 22 or plug 23.After the round piece 22 rolling reaches, the piston rod of the hydraulic cylinder that stroke is adjustable (2) continues to stretch out, and realizes centering pilot or clamping to plug 23, and round piece is accurately located in the whole operation of rolling.
