Specific embodiment
Description of reference numerals：The explanation of Fig. 2 labellings：Clamp pull bar 1, outer arc water tank 2, clamping cylinder 3, disc spring 31, piston
Bar 32, narrow side copper coin 4, wide face copper coin 5, inner arc water tank 6.
The explanation of Fig. 3 labellings：It is narrow while adjust wide hydraulic cylinder 7, angular transducer 8, it is narrow while movable plate 9, it is narrow in backboard 10, it is narrow while
Sufficient roller 11, displacement transducer 12, displacement ratio servo valve 13, narrow side hue angle hydraulic cylinder 14, angle proportional servo valve 15.
The technical solution of the utility model is described further below in conjunction with accompanying drawing.
As shown in Fig. 2 crystallizer width face clamp system of the present utility model mainly includes that two pairs of tops clamp oil with bottom
Cylinder 3（Include disc spring 31, piston rod 32）, clamp pull bar 1 constitute.Wherein pull bar one end nut is pressed in the outer wall of inner arc water tank 6
On, other end is compressed in outer arc water tank 2 by disc spring, so as to narrow side copper coin 4 be clamped.When needing cone adjusting or adjusting wide, it is
Mitigate in the narrow motor process of side copper coin 4 with the frictional resistance between wide face copper coin 5, drawing is promoted by clamping cylinder piston rod 32
Bar 1（Or referred to as push up loose）To offset part disc spring pretightning force.On the one hand crystallizer broadside should be made to the pressure on narrow side reasonable
In the range of be unlikely to produce wide arc gap and caused corner bleed-out between width side, on the other hand reduce narrow side again with broadside
Frictional force selects the pressure of suitable wide face clamping cylinder 3 with this to prevent plowing from copper coin.After adjusting wide, cone adjusting to terminate or
When hydraulic system is out of order, piston rod 32 is retreated, and interior outer arc water tank returns to the default clamping force state of disc spring, it is ensured that wide face
0.3mm is less than with the angle seam between narrow side copper coin 4.The technical security reliability, can also avoid thermal expansion due to narrow side copper coin and
Increase the face pressure between width side and produce the copper coin deformation of creep.
As shown in figure 3, narrow roller 11 sufficient when copper coin 4 is orderly arranged outside each narrow of the present utility model, narrow side movable plate 9, narrow
Side backboard 10.Crystallizer leptoprosopy cone adjusting mechanism mainly includes two pairs of symmetrical shift adjusting machines and angle-adjusting mechanism.Wherein,
Shift adjusting machine includes that narrow side adjusts wide hydraulic cylinder 7, displacement transducer 12, displacement ratio servo valve 13, narrow side to adjust wide hydraulic cylinder 7
While be connected with the center of narrow side backboard 10, another side connection displacement transducer 12 and displacement ratio servo valve 13, and
When two pieces narrow side copper coins 4 are parallel, that is, when there is no taper, it is narrow while adjust wide hydraulic cylinder 7 perpendicular to it is narrow while backboard 10.Angle-adjusting mechanism
Including angular transducer 8, narrow side hue angle hydraulic cylinder 14, angle proportional servo valve 15, angular transducer 8 is arranged on narrow side and adjusts wide
Between hydraulic cylinder 7 and narrow side backboard 10, for measure it is narrow while adjust wide hydraulic cylinder 7 with it is narrow while backboard 10 angle.Narrow side hue angle
Hydraulic cylinder 14 with narrow side backboard 10 at an angle, such as 60 degree, the rear side of narrow side hue angle hydraulic cylinder 14 and angle proportional servo valve
15 connection, so, when narrow 14 liters of time receivings of side hue angle hydraulic cylinder, can drive it is narrow while backboard 10 around its with it is narrow while adjust wide hydraulic cylinder 7
The fulcrum rotation of contact, and then only angle is adjusted.
When device of the present utility model works, crystallizer width face clamp system is identical with the existing course of work, crystallizer
Leptoprosopy cone adjusting mechanism then changes control point, that is, position and the leptoprosopy taper of two narrow central points of side copper coin 4 are calculated, according to narrow
The flexible of wide hydraulic cylinder 7 is adjusted when copper coin 4 controls narrow, the angle of angular transducer 8 is calculated according to leptoprosopy taper, by narrow
Side hue angle hydraulic cylinder 14 is flexible to reach calculating angle.This utility model adjusts the position of wide hydraulic cylinder 7 using narrow side
All it is control accuracy that system can be improved by sensor direct measurement with leptoprosopy taper, reduces system control sytsem and be related to
Difficulty.Relative to existing, by for the position for controlling upper and lower four points of crystallizer leptoprosopy respectively, dress of the present utility model
When putting control, position control point is few, and taper and position can be respectively controlled, and more quickly narrow side copper coin 4 can be carried out
Control.
