Abstract
A cold-rolling strip steel tension straightening machine roller box comprises a roller box body, three rows of supporting rollers, two rows of intermediate rollers and a working roller. The supporting rollers are arranged at the bottom of the roller box body, the intermediate rollers are symmetrically arranged above the supporting rollers, and the working roller is intermediately arranged above the intermediate rollers. The intermediate rollers and the working roller are overall through-length rods, the supporting rollers in each row are composed of a plurality of shorter supporting rollers and one longer supporting roller, axial spacing is formed among the shorter supporting rollers in each row as well as among the shorter supporting rollers and the longer supporting roller, and the axial spacing corresponding to the every two neighboring rows is arranged in a staggered manner. By the design, the intermediate rollers are enabled to contact with the supporting roller in the whole roller length direction, stress situation of the intermediate rollers is greatly improved, and a series of problems brought by uneven stress of the intermediate rollers with an existing roller box structure are solved; tension straightening effect of strip steel is greatly improved, and remarkable direct and indirect economic benefits are achieved; the technology can also be applied to similar operation areas, and the cold-rolling strip steel tension straightening machine roller box is widely applicable.
Description
Technical field
The utility model relates to cold-strip steel tension straingtening implement field, refers to particularly a kind of cold-strip steel seven-roll Abramsen machine roller box.
Background technology
In the process for producing cold rolled strip steel such as Continuous Hot Dip Galvanizing, continuous annealing unit, for improving belt plate shape, make to obtain certain percentage elongation with steel simultaneously, unit has configured seven-roll Abramsen machine.Seven-roll Abramsen machine is comprised of some bending roll roller boxes and some smoothing roll roller boxes, each roller box is comprised of roller box body 1, backing roll 2, intermediate calender rolls 3 and working roll 4, these rollers are pyramid shape and stack layout, as shown in Fig. 1～2: backing roll 2 is arranged in roller box body 1 bottommost, it is comprised of the consistent short backing roll 21 of some length, short backing roll 21 is arranged side by side with three row, and every row vertically spaced set have many; Intermediate calender rolls 3 is arranged in roller box body 1 second layer, is two long support rollers arranged side by side, and it overlays the joint top of the short backing roll 21 of adjacent two row of bottom; Working roll 4 is arranged in roller box body 1 the superiors, is a long support roller, and it overlays the joint top of two long support rollers of the second layer.Because the axial spacing S of the short backing roll 21 of every row is consistent, as shown in Figure 3, therefore, two long support rollers of intermediate calender rolls 3 can not get support force at the axial spacing S place of the short backing roll 21 of correspondence, very easily cause two long support roller distortion of intermediate calender rolls 3 herein, produce roll marks, and then have influence on the roll surface quality of working roll 4, and finally cause belt steel surface to produce the defects such as straightening line, badly influence belt steel product quality, and significantly increased maintenance cost, to production, brought tremendous influence.
Summary of the invention
The purpose of this utility model is exactly to overcome the defect that existing seven-roll Abramsen machine roller box exists, and provides a kind of and can guarantee strip surface quality, ensures and produce the cold-strip steel seven-roll Abramsen machine roller box carrying out smoothly.
For achieving the above object, the cold-strip steel seven-roll Abramsen machine roller box that the utility model is designed, comprise roller box body, be arranged on three row's backing rolls of roller box body bottom, be symmetricly set on the row of two above three row's backing rolls intermediate calender rolls, and be arranged between two parties one above two row's intermediate calender rolls rows working roll, described two row's intermediate calender rolls and row's working roll are whole elongated rod, its special character is: in described three row's backing rolls, each row combines by some short backing rolls and a long support roller, between each row's short backing roll and between short backing roll and long support roller, be formed with axial spacing, axial spacing dislocation corresponding in adjacent two rows is arranged.
Further, in described three row's backing rolls, each row's long support roller is arranged in this row's end, and adjacent two rows' long support roller is arranged crosswise end to end.Like this, can be so that realize axial spacing dislocation layout corresponding in adjacent two rows.
Further, the axial length of described long support roller is 1.3～1.8 times of short backing roll axial length, and preferred version is 1.4～1.6 times, and preferred plan is 1.5 times.
The utility model has the advantage of: designed cold-strip steel seven-roll Abramsen machine roller box, the axial spacing of three row's backing rolls is dislocation and arranges, intermediate calender rolls is all contacted with backing roll on whole roller length direction, greatly improve the stressing conditions of intermediate calender rolls, thereby overcome the series of problems that existing roller box structure causes because of intermediate calender rolls unbalance stress; Greatly improved the tension straingtening effect with steel, the direct economic effect indirect economic effect highly significant bringing.This technology equally also can be applicable to similar field, applied widely, simple in structure, and reliability is strong.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Cold-strip steel seven-roll Abramsen machine roller box shown in figure, comprise roller box body 1, be arranged on roller box body 1 bottom three row's backing rolls 2, be symmetricly set on two row's intermediate calender rolls 3 above of three row's backing rolls 2 and be arranged between two parties two row's intermediate calender rolls 3 row's working roll 4 above, two row's intermediate calender rolls 3 and row's working roll 4 are whole elongated rod, in three row's backing rolls 2, each row combines by some short backing rolls 21 and a long support roller 22, each row's long support roller 22 is arranged in this row's end, and adjacent two rows' long support roller 22 is arranged crosswise end to end; Between each row's short backing roll 21 and between short backing roll 21 and long support roller 22, be formed with axial spacing S, axial spacing S dislocation corresponding in adjacent two rows is arranged.The axial length of long support roller 22 is 1.5 times of short backing roll 21 axial lengths.
By above-mentioned improvement, the intermediate calender rolls 3 of last layer is all contacted with backing roll 2 on whole roller length direction, greatly improve the stressing conditions of intermediate calender rolls 3, thereby overcome the series of problems that existing roller box structure causes because of intermediate calender rolls 3 unbalance stress.The roller length of the short-and-medium backing roll 21 of backing roll 2 and long support roller 22 also can, according to the strip width adjustment of production line, also can be adjusted according to strip width the radical of single-row short backing roll 21 and long support roller 22.
Finally, it should be pointed out that above embodiment is only the more representational example of the utility model.Obviously, the utility model is not limited to above-described embodiment, can also have many distortion.Every foundation technical spirit of the present utility model, to any simple modification made for any of the above embodiments, equivalent variations and modification, all should be thought and belong to protection domain of the present utility model.
