Problems solved by technology

[0008] The technical problem to be solved by the present invention is to provide a rolling mill with a two-dimensional composite structure for the roll stand, which can not only reduce the The deflection deformation in the vertical direction can also reduce the deflection deformation in the horizontal direction. At the same time, due to the improvement of machining accuracy and assembly accuracy, the error of the cross-sectional thickness of the rolled piece is reduced, and the quality of the rolled piece is improved. dimensional accuracy, is a high-precision rolling mill

Embodiment 1

[0050] Fig. 3 is a three-dimensional schematic diagram of the first embodiment of the present invention, Fig. 4 is a side sectional view of the A-A section of Fig. 3 , and Fig. 5 is a side sectional view of the C-C section of Fig. 3 . As shown in Fig. 3, Fig. 4, and Fig. 5, the present embodiment is a twelve-high rolling mill, and the main structure includes a frame 10, and the contents of the frame 10 are equipped with an upper roll stand 50 and a lower roll stand 60, and the upper roll stand 50 and the lower roll stand The roll stand 60 is connected to the upper tower-shaped roll system 30 and the lower tower-shaped roll system 40 respectively in the form of multi-point support beams, and also includes a pressing device 20 and a horizontal support device 80 . The frame 10 is a whole frame surrounded by a panel 11 , a back panel 12 , a top panel 13 and a bottom panel 14 . The surface of the back plate 12 is provided with a material inlet 121 for the rolled piece 100 to enter,...

Embodiment 2

[0065] This embodiment is based on the embodiment 1, adding some additional components to further improve the precision of the rolled piece.

[0066] In this embodiment, the lower roll stand 60 also adopts the same split structure as the upper roll stand in Embodiment 1. In this way, decomposing a large roll stand into several small structures is convenient for processing, because it is difficult to ensure the accuracy of opening holes on objects that are too large and heavy, not to mention opening multiple holes on them. At the same time, it is even more difficult to achieve the precision requirements such as parallelism between the through holes. The present invention decomposes it, processes each through hole on each split body, and then passes through each split when assembling it. The spacers added in the middle of the assembly of the body parts are used to adjust the parallelism of each hole and other indicators, thus improving the machining accuracy and installation acc...

Embodiment 3

[0079] FIG. 15 is a schematic structural view of a third embodiment of the present invention, and FIG. 16 is a side sectional view of FIG. 15 . As shown in Fig. 15 and Fig. 16, the structural difference between this embodiment and the first embodiment is that the depressing device 20 adopts a depressing screw, and the depressing screw passes through the top plate 13 of the frame and is screwed on the frame. On the top plate 13. Another difference in the figure is that the number and position of the vertical supporting devices 70 are the same as those of the pressing devices 20 .

[0080] Compared with the prior art, the present invention has the following advantages:

[0081] The pressing device of the present invention is located in the outermost support beam of the 50 multi-point support beams of the upper roll stand, and the position is as defined above, which reduces the horizontal and vertical deflection deformation of the roll stand, thereby reducing the support roll an...

Abstract

A rolling mill whose roller holder has a 2D combined structure has machine frame, upper roller holder, lower roller holder, upper and lower roller system with tower structure, and symmetric two press-down units. It features that said upper roller holder is composed of a T-shaped upper middle roller holder, the first upper side roller holder and the second upper side roller holder.

Description

technical field [0001] The invention relates to a rolling mill for producing plates and strips, in particular to a rolling mill with a two-dimensional combined structure of roll stands, which can make the rolled plates and strips have the characteristics of high lateral thickness accuracy. Background technique [0002] In the production of plate and strip, the thickness accuracy and flatness of the plate are important indicators to reflect the quality of the product. The thickness automatic control technology has been developed to a very high level in recent years, but the flatness control technology has been under research, and there are still various types of rolling mills in the existing technology when rolling strips with large width-to-thickness ratios. Serious lateral thickness difference problem. The transverse thickness difference of the plate and strip depends on the size and shape of the work roll gap, and one of the main reasons affecting the work roll gap is the...
