Abstract
The invention discloses a spherical bracetype electromagnetic rectifying roller, which is suitable for automatically rectifying various belt materials, and aims at solving the problems of poor safety and poor practicability of the existing electromagnetic rectifying roller. The spherical bracetype electromagnetic rectifying roller comprises annular magnets (1), spherical concave rings (2), spherical convex rings (3), a roller body (4), a roll shaft (5), ball bearings (6), an electromagnet (7), a bracket (8) and the like, wherein both the inner sides of the two ends of the roller body (4) are provided with the annular magnets (1); the roll shaft (5) corresponding to the annular magnets (1) is provided with the electromagnet (7); the two ends of the roll shaft (5) are fixed on the bracket (8); the inner sides of the two ends of the roller body (4) are also provided with the spherical concave rings (2), and the spherical surfaces of the spherical concave rings (2) are mutually laminated with the spherical surfaces of the spherical convex rings (3); the inner sides of the spherical convex rings (3) are provided with the ball bearings (6), and the ball bearings (6) are fixed on the roll shaft (5); and all the centers of the spherical concave rings (2) on the roller body (4) and the all centers of the spherical convex rings (3) on the roller body (4) are mutually coincided at the same point on the axis of the roll shaft (5). Since the two ends of the roller body (4) are provided with the concave spherical surfaces and convex spherical surfaces which are mutually laminated, the moment of sliding friction among the spherical surfaces enables the roller body (4) to be in a stable state when working, thus greatly improving the safety and practicability of the system.
Description
Technical field
The present invention relates to the automatic electromagnetic correction roller of use in a kind of sheet metal strip production, belong to the conveying machinery field.
Background technology
In the sheet metal strip manufacturing line, the sheet metal strip of high-speed cruising is owing to deviation phenomenon appears in a variety of causes, so many places deviation rectification of strip system is set in the band manufacturing line usually.Enumerate various method for correcting error in the patent documentation 200920076118.7, announced a kind of unload-type electromagnetic rectification system simultaneously, can realize simple, fast speed deviation-correcting function.But this unload-type electromagnetic rectifying roller is because a center position at roller body is provided with a bearing fulcrum, under the situation that system cut-off or electromagnet are not worked as yet, the position instability of roller body, roller body are easily crooked and cause the accident, and therefore bring potential safety hazard to production process.
Summary of the invention
Technical matters to be solved by this invention be existing unload-type electromagnetic rectifying roller owing to the potential safety hazard that roller body has only a fulcrum to cause, a kind of safe, practical electromagnetic rectifying roller is provided.
The technical solution used in the present invention is: a kind of spherical bracetype electromagnetic rectifying roller, comprise circular magnet (1), roller body (4), roll shaft (5), electromagnet (7), support (8), detector switch (9) etc., the inboard, two ends of roller body (4) is equipped with circular magnet (1), be provided with electromagnet (7) with the cooresponding roll shaft of circular magnet (1) (5), electromagnet (7) is provided with detector switch (9), the two ends of roll shaft (5) are fixed on the support (8), the inboard, two ends of roller body (4) also is provided with sphere scrobicular ring (2), sphere scrobicular ring (2) equates with the sphere curvature radius of sphere bulge loop (3) and sphere is fitted mutually, sphere bulge loop (3) inboard is provided with ball-bearing casing (6), ball-bearing casing (6) is fixed on the roll shaft (5), and the centre of sphere that is positioned at the concavo-convex ring of all spheres at roller body (4) two ends overlaps on the same point of the axis of roll shaft (5).
In order to prevent that sphere scrobicular ring (2) and sphere bulge loop (3) from sliding in a circumferential direction mutually, the sphere of sphere scrobicular ring (2) is provided with cylinder boss (10), is provided with the diameter circular hole (11) bigger than cylinder boss (10) with cylinder boss (10) corresponding position on the sphere of sphere bulge loop (3).
Principle of work of the present invention is: roller body (4) is under the driving of sheet metal strip, drive sphere scrobicular ring (2), sphere bulge loop (3), ball-bearing casing (6) outer ring rotate around roll shaft (5), when needs are rectified a deviation to band, feed different electric currents in the electromagnet (7) at roller body (4) two ends, under the effect of electromagnetic force between circular magnet (1) and the electromagnet (7), the sphere scrobicular ring (2) at roller body (4) and two ends thereof will be around centre of sphere beat, the axis that makes the axis of roller body (4) and roll shaft (5) at an angle, thereby play the effect of correction band.Detector switch (9) is given electric control system with the size of real-time measuring roll cylindrical shell (4) deflection angle with this signal feedback.
The invention has the beneficial effects as follows: the concavo-convex sphere that mutual applying is set by the two ends at roller body (4), increased the arm of force of the force of sliding friction between sphere, sliding friction torque between sphere makes roller body (4) be in highly stable state when work, even also can remain on normal control position at powering-off state lower roll cylindrical shell (4), improve the reliability and security of system greatly; Because circular magnet and concavo-convex sphere all are arranged on the two ends of roller body (4), make the difficulty of processing of roller body (4) reduce greatly, have improved the economy and the practicality of electromagnetic rectifying roller.
