Abstract
The invention discloses a roller floating rotor wing device which comprises a driving shaft. The driving shaft is sleeved with a basic roller, and a right floating side roller and a left floating side roller which are matched with the basic roller are arranged on the front circumferential face and the rear circumferential face of the basic roller respectively. An inward-concave strip steel machining face is formed by the basic roller, the right floating side roller and the left floating side roller on the circumferential faces. The front circumferential face and the rear circumferential face of the basic roller are respectively provided with a gland, and the glands are connected with the basic rollers through screws. The basic roller is connected with the shaft through a key, power is provided, and the basic roller and strip steel operate synchronously. The floating rotor wing structure is adopted by the left floating side roller and the right floating side roller, the left floating side roller and the right floating side roller rotate along with the forward movement of the strip steel, and therefore the problem that the surface of the strip steel is scraped due to the line speed difference in the rolling process is solved. Practices have proven that the quite obvious effect is achieved on large-caliber welding pipes, large-diameter cold forming sectional steel rollers and strip steel rollers made of special materials.
Description
Technical field
The invention discloses a kind of roller floating rotor device.
Background technology
In actual production process, want to roll out high-quality steel pipe, the optimization of pass design is no doubt important, but the structure of roll itself also plays a part quite crucial, as everyone knows, roll is gyration in the operation of rolling, as shown in Figure 1 and Figure 2, if roll is an integral body, so Va=ω * Ra; Vb=ω * Rb, due to Ra>Rb, so in the identical situation of angular speed (ω), the linear velocity that a is ordered is greater than the linear velocity that b is ordered, the caliber of production is larger, the linear speed of 2 is poor just larger, band steel is when the operation of roll the inside, and the speed of service that will produce roll at a point is fast, and slow with the speed of service of steel, the consequence causing is like this exactly to produce and scratch on the surface with steel, thereby the surface quality of welded tube is reduced.
Summary of the invention
In order better to solve the problem that prior art exists, the invention discloses a kind of roller floating rotor device.
The technical solution used in the present invention is as follows:
A roller floating rotor device, comprises a driving shaft, at described propeller shaft sleeve, a base roller is housed, and respectively establishes the unsteady side roller in the right side being mated, the left side roller that floats on described former and later two peripheries of base roller; Described base roller, the right side roller that floats, the left side roller three of floating form a band steel machined surface concaving on periphery.
On the periphery of the both sides, front and back of described base roller, be respectively provided with a gland, described gland with by screw, be connected with base roller.
Described base roller is connected by key with driving shaft.
Between the mating surface of described base roller and the right side roller that floats, the left side roller that floats, bearing is installed.
Described right gland, left gland and the right side roller that floats, left floating are provided with bearing between side roller.
It with steel machined surface, is the annular concaving.
The beneficial effect that the present invention produces is as follows:
In the structural design of roll, done corresponding adjustment, between the mating surface of base roller and the right side roller that floats, the left side roller that floats, bearing has been installed, right gland, left gland and the right side roller that floats, left floating are provided with bearing between side roller; Base roller, with axle key connecting, provides power, and the synchronous operation of band steel; And the left side roller that floats, the right side roller that floats have adopted the structure of unsteady rotor, moving ahead of steel going along with and rotating, like this in the operation of rolling, just reduced the problem of the scuffing belt steel surface causing because linear speed is poor due to a, 2 of b, facts have proved with roller, have very significantly effect for the band steel of the larger cold-formed steel roll of bigbore welded tube, diameter and special substance.
Accompanying drawing explanation
The existing device front view of Fig. 1;
The existing device side view of Fig. 2;
Fig. 3 front view of the present invention;
Fig. 4 side view of the present invention;
In figure: 1 base roller, the 2 right side rollers that float, the 3 left side rollers that float, 4 screws, 5 right glands, 6 left glands.
The specific embodiment
As shown in Figure 3,4, roller floating rotor device, comprises a driving shaft, at propeller shaft sleeve, a base roller 1 is housed, and respectively establishes the unsteady side roller 2 in the right side being mated, the left side roller 3 that floats on base roller 1 former and later two peripheries; Described base roller 1, the right side roller 2 that floats, the left side roller 3 three's integral body of floating form a band steel machined surface on periphery.It with steel machined surface, is the annular concaving; On the periphery of the both sides, front and back of base roller, be respectively provided with a right gland 5, left gland 6, gland with by screw 4, be connected with base roller.Base roller 1 is connected by key with driving shaft.
In mechanical processing process, base roller 1 and the right side roller 2 that floats, the left side roller 3 that floats need whole turning processing, and during work, the right side roller 2 that floats, the left side roller 3 that floats can freely rotate.
As shown in Figure 3, at base roller and left mating surface A, the B that floats side roller, between place, bearing is installed, at left gland and left floating, between side roller 3, bearing is installed, i.e. C place in figure.The bearing of different size is all installed at A, B, C tri-places; Other corresponding positions at Fig. 3 are also provided with bearing, and base roller, with axle key connecting, provides power, and the synchronous operation of band steel; And the left side roller that floats, the right side roller that floats have adopted the structure of unsteady rotor, moving ahead of steel going along with and rotating, like this in the operation of rolling, just reduced the problem of the scuffing belt steel surface causing because linear speed is poor due to a, 2 of b, facts have proved with roller, have very significantly effect for the band steel of the larger cold-formed steel roll of bigbore welded tube, diameter and special substance.
