The specific embodiment
The utility model provides a kind of roller device for conticaster, realizes the online adjustment of pair of rollers opening degree, simplifies the adjustment flow process of roller opening degree.In addition, the utility model also provides a kind of conticaster that comprises above-mentioned roller device.
In order to make those skilled in the art can better understand the utility model, with embodiment, the utility model is described in detail below with reference to the accompanying drawings, wherein, identical label represents same parts all the time.
With reference to figure 1, Fig. 1 is the structural representation of the roller device in an embodiment of the present utility model.
In a kind of specific embodiment, roller device provided by the utility model comprises support 1 and is articulated in respectively a pair of roller that is oppositely arranged on support 1, described a pair of roller can be called the first roller 2 and the second roller 8, and the first roller 2 and the second roller 8 all are articulated on support 1 by rotating shaft, that is, the first roller 2 and the second roller 8 can rotate with respect to support 1.Minimum range between the periphery of the periphery of the first roller 2 and the second roller 8 is the roller opening degree.Square billet is placed between two rollers, and namely the width of square billet should be unanimous on the whole with the roller opening degree.
Have at least a roller to be articulated on support 1 by eccentric shaft 3 in described a pair of roller.Eccentric shaft 3 has certain eccentric amount e, as shown in Figure 2.Can there be a roller to be articulated on support 1 by eccentric shaft 3, and the another one roller is articulated on support 1 by the rotating shaft of measuring without acceptance of persons, in this case, by the angle of regulating this eccentric shaft 3 with respect to support 1, change the position of the rotation of the first roller 2, it departed from or move towards the second rod 8, just can realize the adjustment to the distance between the rotation of two rollers, and then realizing the adjustment of pair of rollers opening degree.In addition, two rollers can also be articulated on support 1 by eccentric shaft 3 respectively.
Specifically, eccentric shaft 3 can be fixed on support 1, for example, the two ends of eccentric shaft 3 is fixed on support 1, and at the two ends of eccentric shaft 3, axle sleeve 7 is installed all; And a roller can be arranged in described a pair of roller, and for example the first roller 2, be articulated on eccentric shaft 3, that is and, the first roller 2 is around eccentric shaft 3 rotations.Between the first roller 2 and eccentric shaft 3, roller shell 4 and bearing 5 can be set further, supporting the first roller 2, and can be around eccentric shaft 3 rotations.Certainly, when the assembling roller device, should set according to the standard scale scope of roller opening degree the initial angle of eccentric shaft 3, in order to guarantee that the roller opening degree is in critical field.
In addition, two rollers can also all be articulated on support 1 by eccentric shaft 3, like this, when the pair of rollers opening degree is adjusted, can only rotate an eccentric shaft 3, also can rotate simultaneously two eccentric shafts 3; Simultaneously, for the situation that an eccentric shaft 3 only is set, the adjusting range that two eccentric shafts 3 can increase the roller opening degree is set.
In order to reduce as much as possible the wearing and tearing between eccentric shaft 3 and roller, oil groove 301 and oilhole 302 can be set, in order to form oil lubrication between the contact-making surface of eccentric shaft 3 and corresponding roller, to improve the service life of roller and eccentric shaft 3 on eccentric shaft 3.
Cause the roller opening degree to change in the roller device serious wear and exceed the standard scale scope, when needing the pair of rollers opening degree to adjust, only need the suitable eccentric adjustment axle 3 of attendant with respect to the angle of support 1, by to the adjusting of the distance between rotating shaft separately of a pair of roller, realize the adjusting of pair of rollers opening degree, the roller opening degree is come back in critical field.That is, if when the roller opening degree becomes large, the distance between the axis of two rotating shafts is reduced, if when the roller opening degree diminishes, the distance between the axis of two rotating shafts is increased.
Roller device provided by the utility model has been realized the online adjustment of pair of rollers opening degree, do not need whole fan-shaped section or roller are disassembled in whole adjustment process, thereby significantly simplified the adjustment flow process, and shortened the adjustment time, reduced the input of manpower in the adjustment process, help to improve the service efficiency of roller device, reduce production costs, improve output.
In order to facilitate the adjusting of the angle between and support 1 relative to eccentric shaft 3, roller device provided by the utility model comprises tumbler 6, to drive the rotation of eccentric shaft 3 by the rotation of tumbler 6.
The concrete form of tumbler 6 is more, and for example, what tumbler 6 can be concrete is stock, have large end and small end, be formed with engaging groove 601 on large end, corresponding, the joining section 303 that matches with engaging groove 601 is set on eccentric shaft 3, and this joining section 303 extends out from an end of eccentric shaft 3.When the angle of eccentric shaft 3 is regulated, tumbler 6 can be locked on eccentric shaft 3 by the cooperatively interacting locking between engaging groove 601 and joining section 303, thereby complete rotation to eccentric shaft 3.In order being in course of adjustment, tumbler 6 to be locked on eccentric shaft 3, can on the engaging groove 601 of tumbler 6, internal thread to be set, and on the joining section 303 of eccentric shaft 3, the external screw thread that matches is set.Certainly, tumbler 6 provided by the utility model is not limited to this, identical and the coaxial installing hole of size can also be set on the joining section 303 of tumbler 6 and eccentric shaft 3, two installing holes over against the time, adopt alignment pin to be inserted in the locking that realizes in two installing holes tumbler 6 and eccentric shaft 3, after adjusting end, then alignment pin is extracted, tumbler 6 is separated getting final product with eccentric shaft 3.
In addition, the utility model also provides a kind of conticaster, and this conticaster comprises above-mentioned roller device, has advantages of consistently with above-mentioned roller device, and other structures of conticaster please refer to prior art, do not repeat them here.
Above to roller device provided by the utility model and comprise that the conticaster of this roller device describes in detail; although represented and described embodiment more of the present utility model; but those skilled in the art should understand that; in the situation that do not break away from principle of the present utility model and the spirit that is limited its scope by claim and equivalent thereof; can modify and perfect to these embodiment, these modifications and improve also should be in protection domain of the present utility model.
