Abstract
The utility model relates to a multi-point press controller in the shape of a plate for a rolling mill, which belongs to the field of the mechanical device. The multi-point press controller in the shape of a plate for a rolling mill is composed of a pair of top and bottom working rolls which make a work piece as a symmetry plane, two pairs of top and bottom first layers of the support rolls, three pairs sectional type bearing rolls of the back lining, and a pair of top and bottom roll boxes which are arranged in a machine frame. The multi-point press controller in the shape of a plate for a rolling mill is characterized in that at least one of the upper part of the upper roll box or the lower part of the lower roll box is provided with the multi-point press and a control hydraulic cylinder in the shape of a plate. The multi-point press controller in the shape of a plate for a rolling mill can more effectively and flexibly adjust the rolling force and the roll shapes of the working rolls, and superior products with smaller thickness difference and smooth plate shape can be obtained.
Description
Technical field
The utility model belongs to the plant equipment field, specially refers in metallic plate, band are produced, and a kind of multiple spot that is used for milling train is depressed and plate shape control device.
Background technology
In prior art, be generally used for plate, the milling train of band production has 2 rollers, 4 rollers, (domestic general system refers to 6 roller machines to HC, its original meaning is from " Hitachi's high accuracy control milling train "), UC (referring to omnipotent convexity control milling train), PC (the paired cross rolling mill of roll) milling train, CVC (regulating the control milling train continuously) and various multi-roll mill, these milling trains all are that the mode that adopts two-point to depress is operated, and screwdown gear all is positioned at the roll neck place of roll, their common disadvantage, be to make roll produce bigger flexural deformation, control this distortion in order to take measures, reduce its influence to strip thickness, especially the influence of lateral thickness difference, China and foreign countries had made various research and repetition test with the provisional capital, as far back as 1989, it is 89202658.8 to have reported the work of this respect that number of patent application is just arranged, the Position Design of screwdown gear and cushion block is being positioned near the working roll axis middle part, and the progressive that this patent possesses skills has reduced the lateral thickness difference during the strip material is produced.Though screwdown gear no longer is positioned at the roll neck place of roll, but concentrate to the middle part, it also belongs to two-point eventually and depresses mode.Continuous progress along with the level of production, precision prescribed to plate, strip product improves day by day, also wish to seek a kind of control mode of depressing and adjusting working roll of adjusting more effectively, neatly, thereby obtain thick difference is as far as possible little, plate shape is good high-quality plate, strip product, for this reason, we develop with great concentration and experimental development go out the new device that plate shape control function was depressed and had to a kind of multipoint mode.Well-content plate, strip-rolling product have been obtained.
Summary of the invention
The utility model technical issues that need to address are to depress at existing milling train two-point, depress and plate shape control device and redesign a kind of multiple spot.The purpose of this utility model adopts following technical proposals to realize, a kind of multiple spot that is used for milling train is depressed and plate shape control device, comprise with the workpiece being a pair of upper working rolls and lower working rolls of the plane of symmetry, ground floor backing roll about in the of two pairs, the three pairs of segmented backing cloth bearing rollers, a pair of up-down rollers case, and in the device frame, it is characterized in that, between top roll upper box part or lower roll lower box part and frame, be provided with place's multiple spot at least and depress and plate shape control device.Described multiple spot is depressed, its position be located at traditional 2 depress between, its pressure point number can be provided with at 3 o'clock by every row and adjust to 11 point ranges, the pressure point number is selected along with plate, strip product width and precision.
The beneficial effects of the utility model are that depressing of this multipoint mode can be adjusted roll-force more effective, neatly and adjust working roller, makes it obtain the quality product that thick difference is littler, plate shape is smooth.

The specific embodiment
With reference to Fig. 1, Fig. 2, the device that the milling train two-point is depressed in the expression prior art wherein is that the plane of symmetry is provided with a pair of upper working rolls and lower working rolls 1 with work, a pair of backing roll 2 up and down, a pair of metal (upper roller (or seat) 3.In the utility model, with reference to Fig. 3, segmented backing cloth bearing roller 3 is by 4 bracketings of pair of rolls case up and down, and place the inside of frame 5, on the top of top roll case and the bottom of lower roll case is provided with that 3 points (multiple spot) are depressed and plate shape control hydraulic cylinder 6,6 ' and 6 "; it can be adjusted flexibly and depress and control panel shape, and plate, band that quilt is rolled are 7.
Claims (2)
1, a kind of multiple spot that is used for milling train is depressed and plate shape control device, comprise with the workpiece being a pair of upper working rolls and lower working rolls of the plane of symmetry, ground floor backing roll about in the of two pairs, the three pairs of segmented backing cloth bearing rollers, a pair of up-down rollers case, and device is in frame, it is characterized in that between top roll upper box part or lower roll lower box part and frame, at least one place is provided with multiple spot and depresses and plate shape control device.
2, the multiple spot that is used for milling train according to claim 1 is depressed and plate shape control device, it is characterized in that, described multiple spot is depressed, its position be located at traditional 2 depress between, its pressure point number can be provided with at 3 o'clock by every row and select to adjust according to product width to 11 point ranges, and this device can be established 1 row to 2 row.
