The specific embodiment
Below incite somebody to action its operation principle in detail, and describe embodiment of the present utility model with reference to the accompanying drawings in detail.
In the hot strip rolling operation of rolling, be the coil of strip quality that ensures that coiling machine batches, must arrange a cover flipper guide device at the coiling machine inlet, band steel and reel center line are consistent when batching the band steel with assurance.But in existing hot rolling line, coiling machine entrance side guide plate arrangement all adopts single liner plate to finish being with the guide function of steel basically.Because liner plate is that fixed installation itself is motionless, when the band steel passed through, liner plate directly contacted with the strip and the phase mutual friction in its production process, cause wear liner to be exceedingly fast, need change liner plate every day one time, not only increase the weight of working strength of workers, and influence production efficiency greatly.
The utility model is by structural change, respectively be provided with 2 groups of Roll Collar assemblings 1 with eccentric shaft structure in the both sides of guide and guards, and correspondingly respectively be provided with 1 group of driving mechanism 2 in both sides, make per 1 group of driving mechanism 2 drive 2 groups of Roll Collar assembling 1 motions, when described driving mechanism 2 moves, the eccentric shaft 4 that makes Roll Collar assembling 1 clockwise or be rotated counterclockwise 90 °, make the surface of the edger roll 3 of Roll Collar assembling 1 be higher or lower than the surface of foreplate simultaneously, like this, can realize alternately carrying out guide and guard for what the band steel was advanced.
Owing to be provided with rolling bearing 5 in the Roll Collar assembling 1, when the edger roll 3 of Roll Collar assembling 1 contacts with the strip, can under the drive of band steel, therewith rotatablely move synchronously, avoided the rigidity friction.Therefore, the life-span of Roll Collar assembling 1 is longer.And when work most of the time edger roll 3 the surface contact with the strip and under the drive of band steel, rotate, greatly reduce contacting and the rate of wear of foreplate of band steel and foreplate.Therefore, adopt foreplate and Roll Collar alternately advancing of steel of band to be carried out guide and guard, not only improved the service life of power reel inlet both sides foreplates, reduced the replacing frequency of foreplate, saved material and labour cost, guaranteed that equally also the band steel is consistent with the center line of reel.
As shown in Figure 1, power reel guide and guards of the present utility model comprises the foreplate 10 that is arranged on the guide and guards both sides, and the Roll Collar assembling 1 and the driving mechanism 2 that are arranged on the guide and guards both sides, this Roll Collar assembling 1 is arranged between the foreplate 10 of both sides, and alternately carries out guide and guard for advancing of steel of band with foreplate 10.
As shown in Figure 2, Roll Collar assembling 1 described in the utility model comprises edger roll 3, eccentric shaft 4, rolling bearing 5 and supporting seat 6; Rolling bearing 5 is arranged between edger roll 3 and the eccentric shaft 4, and the lower end of eccentric shaft 4 is arranged in the guide plate frame 11, matches with driving mechanism 2 by supporting seat 6 and guide plate frame 11 in the upper end; Driving mechanism 2 comprises the gear 7 with eccentric shaft 4 upper end secure fit, the tooth bar 8 that is meshed with gear 7, and the hydraulic cylinder 9 that is connected with tooth bar 8; When driving mechanism 2 motions, hydraulic cylinder 9 drives tooth bar 8 and makes back and forth movement, the eccentric shaft 4 that makes Roll Collar assembling 1 is clockwise or be rotated counterclockwise 90 °, make simultaneously Roll Collar assembling 1 edger roll 3 the surface or be higher or lower than the surface of foreplate, to realize alternately serving as to be with the guide and guard of carrying out that steel advances.
The utility model respectively is provided with 2 groups of Roll Collars assembling 1 in the guide and guards both sides, and 1 group of driving mechanism 2 respectively is set in the guide and guards both sides simultaneously, and per 1 group of driving mechanism 2 drives 2 groups of Roll Collars simultaneously and assembles 1 reciprocating.
According to preferred embodiment of the present utility model, as depicted in figs. 1 and 2, the edger roll 3 of Roll Collar assembling 1 is installed on the eccentric shaft 4 that two ends are equipped with 2 rolling bearings 5, the lower end of eccentric shaft 4 is installed in the installing hole of guide plate frame 11, matching with the gear 7 of driving mechanism 2 by the through hole of supporting seat 6 and guide plate frame 11 in the upper end of eccentric shaft 4, thereby forms Roll Collar assembling 1.The utility model is provided with 4 groups of Roll Collar assemblings 1 altogether, forms the power reel guide and guards under the support of supporting seat 6, and is separately positioned on the both sides of output strip line coiling machine inlet.
As shown in Figure 3, edger roll 3 upper ends of Roll Collar assembling 1 and 7 fixed installations of the gear of driving mechanism 2, the tooth bar 8 of driving mechanism 2 is meshed with two gears 7 simultaneously, and tooth bar 8 is connecting hydraulic cylinder 9.When the operation of band steel, because the impulsive force of band steel toe portion is bigger, cause the damage of edger roll bearing easily, need utilize this moment foreplate that the band steel is led.Therefore, earlier Roll Collar assembling 1 is arranged at the home position, that is, edger roll 3 surfaces of Roll Collar assembling 1 are lower than the surface of foreplate 10, thereby edger roll 3 is not contacted with the strip, shown in Fig. 4 A; After coiler mandrel is nipped the band steel, hydraulic cylinder 9 motions in the driving mechanism 2, promote tooth bar 8 motions, tooth bar 8 driven gears 7 half-twists, thereby make and gear 7 joining eccentric shaft 4 half-twists, that is, the surface of edger roll 3 is higher than the surface of foreplate 10 at this moment, and have only edger roll 3 to contact, shown in Fig. 4 B with the limit portion of band steel; And edger roll 3 rotates synchronously with band steel direction of advance under the effect of frictional force, finishes the guiding to the band steel.
According to preferred embodiment of the present utility model, when Roll Collar assembling 1 was in the home position, edger roll 3 can be lower than foreplate 10 surperficial 5mm, and when Roll Collar assembling 1 is in the operating position, edger roll 3 can be higher than foreplate 10 surperficial 10mm, so that it does not touch the band steel simultaneously.
Though show exemplary embodiment of the present utility model in conjunction with the accompanying drawings, it should be understood that the utility model is not limited to the foregoing description, but under the situation that does not break away from the utility model scope, can carry out the modification of various malformations and size.
