Abstract
The utility model belongs to a hot rolling device for a seamless steel pipe, and relates to a core holding device of a rolled steel pipe. The utility model solves the technical problems that the core holding device of the prior rolled steel pipe can not effectively position a pierced billet, thereby causing a core rod and a hollow billet to wobble during the rolling process. The core holding device comprises a machine frame (1) and a travel adjustable hydraulic cylinder (2), as well as a T-shaped oscillating arm (5), a first V-shaped oscillating arm (10) and a second V-shaped oscillating arm (12) and a multiple-head oscillating arm (18) which are connected by three connecting rods and distributed in an inverted triangle shape. A fixed mandrel B (13) penetrates through the middle parts of the first V-shaped oscillating arm (10) and the second V-shaped oscillating arm (12) in sequence to cause the first V-shaped oscillating arm (10) and the second V-shaped oscillating arm (12) to penetrate together; and a left swinging head (25) and a right swinging head (26) of the multiple-head oscillating arm (18) and a right swinging head (27) are mutually and fixedly connected and are distributed in a fan shape. The utility model is matched with a complete transition mechanism to achieve the operation of moving specific workpieces into and out of a workpiece center line, thereby solving the wobbling problem of rolled workpieces and improving the production efficiency.
Description
Technical field
The present invention relates to a kind of seamless steel pipe hot-rolling equipment, particularly a kind of core holding device of seamless steel pipe oblique milling
Background technology
At present, be that Jiang's plug penetrates hollow billet when rolling seamless steel pipe, send in the milling train again to be rolled; Rolling mode is mainly complete floating mode and restraint mode.The main feature of complete floating mode is that plug floats, with hollow forging enters milling train outlet platform, the circulation of taking off plugs such as rod, cooling more together, its advantage is that rolling rhythm is fast, and many plugs recycle, and the plug wearing and tearing are less, shortcoming is that the equipment composition is many, and the investment of equipment and factory building is big.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 the equipment composition is few, and the investment of equipment and 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 exist device structure unreasonable, cause functions of the equipments poor, in the operation of rolling, can not effectively locate hollow billet and plug, cause the violent shake in the operation of rolling of hollow billet and plug, influenced the stability of the operation of rolling and the dimensional accuracy and the surface quality of hollow billet, influenced the difficult problem that plug partial circulating rolling mill practice is promoted so the reliable guiding under the plug partial circulating rolling mode becomes.

The present invention is achieved by following scheme:
A kind of core holding device of rolled steel tube, comprise frame 1, T shape lever 5, the first V-arrangement lever 10, the second V-arrangement lever 12, bull lever 18, first connecting rod 17, second connecting rod 16, hydraulic cylinder that third connecting rod 23 and stroke are adjustable or cylinder 2, the stationary spindle A6 that described T shape lever 5 is provided with on it rotates a side of the oblique upper that is arranged on described frame 1, the first V-arrangement lever 10 and the second V-arrangement lever 12 rotate around the stationary spindle of installing in the middle, these two V-arrangement levers are arranged on the opposite side of the oblique upper of described frame 1, and the V-shaped part that makes the first V-arrangement lever 10 towards with the V-shaped part of the second V-arrangement lever 12 towards opposite setting, bull lever 18 rotates the oblique below that is arranged on the described frame 1, first hinge 25 of bull lever 18 around stationary spindle C21, to be distributed in stationary spindle C21 be on the circumference in the center of circle with fan-shaped for second hinge 26 and tri-joint mechanism 27; The output shaft of hydraulic cylinder that described stroke is adjustable or cylinder 2 is hinged by the T shape bottom of connector A4 and T shape lever 5, top one end of T shape lever 5 is set with guide roller A8, the top other end of T shape lever 5 is hinged by an end of connector B3 and third connecting rod 23, the other end of third connecting rod 23 is hinged by second hinge 26 in connector C20 and the bull lever 18, first hinge 25 of bull lever 18 is hinged by an end of connector D19 and second connecting rod 16, the other end of second connecting rod 16 is hinged by an end of the connector E15 and the second V-arrangement lever 12, the other end of the second V-arrangement lever 12 is set with guide roller B11, the tri-joint mechanism 27 of bull lever 18 is hinged by an end of connector F22 and first connecting rod 17, the other end of first connecting rod 17 is hinged by an end of the connector G14 and the first V-arrangement lever 10, the other end of the first V-arrangement lever 10 is set with guide roller C9, the motion of hydraulic cylinder that stroke is adjustable or cylinder 2 makes guide roller A8, guide roller B11 and guide roller C9 are the center with the workpiece centre, open and close identical amount synchronously, realization is to the stable guiding in steel pipe 7 operations of rolling, and the opening degree of guide roller is adjustable arbitrarily.
Stationary spindle A6, stationary spindle B13 and stationary spindle C21 generally are del and distribute on described frame 1; Guide roller A8, guide roller B11 and guide roller C also are del and distribute.
The invention has the beneficial effects as follows the center line of in the operation of rolling of steel pipe, accurately locating workpiece, what efficiently solve workpiece anti-rejectionly mays I ask topic, cooperate the operation that has realized specific workpiece is moved into synchronously, shifts out work centre line with supporting translation mechanism, realized the reliable guiding under the plug partial circulating mode.
