Steel rolling cold-rolling mill frame of the present utility model has the following advantages:

(1) by adopting multiple cold roll group distributed side by side, and each cold roll group all adopts is inclined ten roller cold roll groups, and the efficiency making steel rolling cold rolling is high, and precision is high;

(2) to be positioned at below steel plate by having one between adjacent two cold roll groups and for the support tensioner of tensioning steel plate, to make steel plate keep higher flatness in whole transmission process, and then ensure the effect that steel rolling is cold rolling;

(3) by setting up calibrator before batching, can detect by the thickness of cold rolling rear steel plate, ensureing the quality that steel rolling is cold rolling.

Detailed description of the invention

By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.

As shown in Figure 1, steel rolling cold-rolling mill frame, there is cold roll group 3, calibrator 4, guide roller 5 and coiling machine 6 that the uncoiling case 2 for uncoiling steel plate 1 and multiple (four in such as Fig. 1) by steel plate 1 successively process distribute side by side, there is between adjacent two cold roll groups 3 one to be positioned at below steel plate 1 and for the support tensioner 7 of tensioning steel plate 1, what each cold roll group 3 all adopted is inclined ten roller cold roll groups.

As shown in Figure 2, cold roll group 3 comprises and to be positioned at above steel plate 1 and the topping roll 1 of tangent transmission in turn, topping roll 2 32, topping roll 3 33, topping roll 4 34, topping roll 5 35 and to be positioned at below steel plate 1 and the bottom roll 1 of tangent transmission in turn, bottom roll 2 37, bottom roll 3 38, bottom roll 4 39, bottom roll 5 40; The distribution of topping roll 1 and mirror image identical with bottom roll 1 specification, the distribution of topping roll 2 32 and mirror image identical with bottom roll 2 37 specification, the distribution of topping roll 3 33 and mirror image identical with bottom roll 3 38 specification, the distribution of topping roll 4 34 and mirror image identical with bottom roll 4 39 specification, topping roll 5 35 and mirror image distribution identical with bottom roll 5 40 specification.Wherein, tangent with topping roll 2 32 while of described topping roll 3 33 and topping roll 5 35; With bottom roll 4 39 while of described bottom roll 3 38 and bottom roll 5 40.

Due to topping roll 5 35 and bottom roll 5 40 direct cold rolling steel plate 1, therefore topping roll 5 35 and bottom roll 5 40 easily wear and tear, once there is the phenomenon of wearing and tearing in topping roll 5 35 and bottom roll 5 40, only need during practical operation to replace topping roll 5 35 and bottom roll 5 40, and do not need the roll replacing other, also save production cost while ensure that the cold rolling precision of steel rolling.

The central point of topping roll 1, topping roll 2 32, bottom roll 1 and bottom roll 2 37 is all located on the same line.The diameter of topping roll 1 is greater than the diameter of topping roll 2 32, the diameter of topping roll 2 32 is greater than the diameter of topping roll 3 33, the diameter of topping roll 3 33 is greater than the diameter of topping roll 5 35, the diameter of topping roll 5 35 is greater than the diameter of topping roll 4 34, also illustrate that the diameter of bottom roll 1 is greater than the diameter of bottom roll 2 37 simultaneously, the diameter of bottom roll 2 37 is greater than the diameter of bottom roll 3 38, the diameter of bottom roll 3 38 is greater than the diameter of bottom roll 5 40, the diameter of bottom roll 5 40 is greater than the diameter of bottom roll 4 39, namely the relatively little topping roll 5 35 of diameter dimension and the relatively little bottom roll 5 40 of size is adopted to carry out direct cold rolling steel plate 1, not only ensure that the working strength of topping roll 5 35 and bottom roll 5 40, also ensure that the precision that steel plate 1 is cold rolling simultaneously.

Certainly; the utility model can also have various embodiments; when not deviating from the utility model spirit and essence thereof; those of ordinary skill in the art can openly make various corresponding change and modification according to of the present utility model, but these change accordingly and are out of shape the protection domain that all should belong to the claim appended by the utility model.
