Described sensor 8 adopts rope sensor or turn-sensitive device, and sensor contact device 7 is the stay cord of rope sensor.
Described fixedly top roll 5, lower rubber roller 6 are in the whole set equipment Design and manufacturing process, and its position can be replaced, and namely fixedly top roll 5 is in lower rubber roller 6 lower positions, and other principle is constant.
The course of work of the present utility model is:
1, when lower rubber roller 6 (switches between the limiting condition after lower roll rises) rise/fall mutually from up-down rollers in certain interval range, rolls the also thereupon change of curvature deformation that sheet material produces.
2, in rolling process, determine that as required the different amounts of being pressed into makes sheet material produce deformation, thereby reach the required radius of curvature that rolls sheet material.
3, but sensor 8 Real-time Measurings measure the amount of being pressed into after lower rubber roller 6 rises, thereby derive the radius of curvature that rolls sheet material; Otherwise, as long as know the radius of curvature (ellipticity form) that rolls sheet material, also can be by operation line speed and the required parameters such as different curvature radius that roll oval workpiece at the thickness of slab of numerical control device 1 input workpiece, plate length, sheet material yield strength, lower rubber roller 6, go out the amount of being pressed into of lower rubber roller 6 by sequential operation, can realize Full-numerical-control, and one-time formedly roll out oval workpiece.
