Abstract
The utility model pertains to the field of a steel pressurization device, in particular to a convexity degree control device of a grinding mill. The utility model is characterized in that a rack which meshes with a gear sheet which is positioned at a back lining bearing is positioned between the upper back-up rolls A and B and upper back-up rolls of C and D. A servo hydraulic oil tank is connected with the rack. The board from control is realized by adjusting the form of the four back-up rolls of A, B, C and D. The back and forth movement of the rack which is driven by the hydraulic servo oil tank causing the gear sheet to produce an eccentricity, which makes the back lining bearing to change the convexity grade to control four or two back-up rolls. Thus, the planeness of the steel belt is increased. Experiments have proved that the convexity degree control device of the grinding mill of the utility model can achieve a great board form controlling effect and therefore can be applied to each kind of grinding mill.
Description
Technical field
The utility model belongs to the steel rolling equipment field, particularly a kind of 20 roller mill crown control devices.
Background technology
Present 20 roller mill convexitys control can be divided into radially roll forming guiding mechanism and axially roll forming guiding mechanism, and radially guiding mechanism is adopted in practice more.Its basic principle is in the saddle between the back lining bearing of backing roll B, C, outside the interior eccentric hoop of screwdown gear, refill eccentric hoop outside, this eccentric hoop drives the eccentric hoop rotation by adjusting hydraulic cylinder or hydraulic motor respectively, the rotation of any one outer eccentric hoop can both make the axle of backing roll group produce corresponding distortion, reach elimination by the part of strip or whole in uneven thickness, this control device can only be controlled two backing rolls of B, C and control template, the working control poor effect, the adjustment dynamics is not strong.
Summary of the invention
The purpose of this utility model provides a kind of 20 effective roller mill crown control devices of controlling.
The purpose of this utility model realizes by following technical proposals:
According to 20 roller mill crown control devices of the present utility model, it is characterized in that between upper support roller A, the B, between upper support roller C, the D toothed rack is set respectively, be meshed with the gear sheet on being located at back lining bearing, a servo-hydraulic oil cylinder is connected with described tooth bar.
Adopt 20 roller mill crown control devices of the present utility model, the control of 20 roller mill roll forming convexitys is to control template by the roll shape of adjusting A, B, C, four backing rolls of D, promote tooth bar with the servo-hydraulic oil cylinder and move back and forth driven gear generation off-centre, make back lining bearing change convexity and control 4 or 2 backing rolls, thereby improve the steel band flatness.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with the description of drawings specific embodiment of the present utility model.
As shown in Figure 1, label 1 is a working roll, and 2 is first intermediate calender rolls, and 3 is second intermediate calender rolls, 4 is backing roll, 7 for supporting roll shaft, and 8 is the backing roll back lining bearing, and 9 is steel band, 20 roller mill crown control devices of the present utility model, it is characterized in that between upper support roller A, the B, between upper support roller C, the D toothed rack 6 is set be meshed with gear sheet on being located at back lining bearing 8, a servo-hydraulic oil cylinder 5 is connected with described tooth bar 6.E among the figure, F, G, H are backing roll.
Evidence is adopted this control device to produce the steel band glacing flatness and is significantly improved.
