Be labeled as among the figure: upper straightening roll 1, fore bearing 2, bearing holder (housing, cover) 3, gear shaft 4, reducing motor 5, displacement transducer 6, gear ring 7, key 8, following smoothing roll 9, rear bearing group 10, driven gear 11, gear distribution box 12, drive motors 13, decelerator 14, travelling gear 15, upper machine body 16, lower body 17, front-end bearing pedestal 18, rear bearing block 19.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As Fig. 1～section straightener shown in Figure 4, comprise upper straightening roll 1 that is installed on the upper machine body 16 and the following smoothing roll 9 that is installed on the lower body 17, described down smoothing roll 9 is drive roll, and also comprises and be used for separately adjusting device that each upper straightening roll 1 and each time smoothing roll 9 are axially adjusted.The adjusting device that on straightener, is provided for making each upper straightening roll 1 and each time smoothing roll 9 to axially move separately, thus the pass adjustment can be finished quickly and easily.Described adjusting device both can be a whole mechanism, and this integral body mechanism need have the function of separately each upper straightening roll 1 and each time smoothing roll 9 axially being adjusted; This adjusting device also can be the independent agency that is connected with each time smoothing roll 9 with each upper straightening roll 1 respectively.
As Fig. 2～Fig. 4, be built-in with one in the described lower body 17 and be used to drive the gear distribution box 12 that each time smoothing roll 9 rotates synchronously, the drive motors 13 of the input of described gear distribution box 12 and lower body 17 outsides is in transmission connection.Built-in one is used to drive the gear distribution box 12 that each time smoothing roll 9 rotates synchronously in lower body 17, and existing each roller of cancellation is distributor box and universal-joint spindle independently, makes the complete machine floor space little, and weight saving has also stayed locational space for the installation of adjusting device.Like this, adjusting device can be directly installed on the side of lower body 17 and axially be in transmission connection with the axle head of each time smoothing roll 9.
As Fig. 3, the inside concrete structure of described gear distribution box 12 comprises the driven gear 11 that is set with and is fixed on each time smoothing roll 9, and the travelling gear 15 that all meshes with adjacent two driven gears 11, the rotating shaft of one of them travelling gear 15 is in transmission connection by decelerator 14 and drive motors 13.The kind of drive of said gear distributor box 12 has simply realized the Synchronous Transmission to each time smoothing roll 9.Wherein, the facewidth of travelling gear 15 is greater than the facewidth of driven gear 11, and travelling gear 15 axial restraints after smoothing roll 9 moves axially by adjusting device so instantly, can guarantee the engagement of travelling gear 15 and driven gear 11.
The smoothing roll adjusting device of the utility model section straightener, upper straightening roll 1 adopts identical structure with following smoothing roll 9.As shown in Figure 1, when smoothing roll is upper straightening roll 1, described upper straightening roll 1 supports by fore bearing 2 and rear bearing group 10, described fore bearing 2 be installed in the front-end bearing pedestal 18 and with its axial sliding fit, described rear bearing group 10 is installed in the bearing holder (housing, cover) 3, described bearing holder (housing, cover) 3 is installed in the rear bearing block 19, the screw thread rotation set has a gear ring 7 on the bearing holder (housing, cover) 3, described gear ring 7 and gear shaft 4 engagements, described gear shaft 4 is in transmission connection with reducing motor 5, described gear ring 7 is axially fixed in the rear bearing block 19, and described bearing holder (housing, cover) 3 circumferentially is fixed in the rear bearing block 19.
The operation principle of this adjusting device is: 4 rotations of reducing motor 5 driven gear axles, gear ring 7 is rotated, because gear ring 7 and bearing holder (housing, cover) 3 thread connection, and gear ring 7 is axially fixed in the rear bearing block 19, bearing holder (housing, cover) 3 circumferentially is fixed in the rear bearing block 19, relative rear bearing block 19 axially-movables of bearing holder (housing, cover) 3 meetings when therefore gear ring 7 rotates, and by 1 axially-movable of rear bearing group 10 drive upper straightening rolls, fore bearing 2 axially slides in front-end bearing pedestal 18 simultaneously; After adjustment finished, reducing motor 5 quit work, because bearing holder (housing, cover) 3 is circumferentially fixing, therefore can axially-movable not take place because of the rotation of upper straightening roll 1, guaranteed that upper straightening roll 1 axial location is constant.Wherein, front-end bearing pedestal 18 connects as one structure with rear bearing block 19, improves the globality and the stability of equipment.In addition, bearing holder (housing, cover) 3 can circumferentially be fixed in the rear bearing block 19 by key 8.For the distance of each upper straightening roll 1 axially-movable is controlled accurately, the rear end of described upper straightening roll 1 is connected with displacement transducer 6, and displacement transducer 6 is connected with display unit.Displacement transducer 6 is connected with display unit,, thereby finishes the pass adjustment quickly and easily so that the amount of upper straightening roll 1 axially-movable is controlled accurately.
As shown in Figure 2, for the axial adjustment of smoothing roll 9 down, adopt with upper straightening roll 1 and axially adjust identical mode, promptly play smoothing roll 9 to support by fore bearing 2 and rear bearing group 10, described fore bearing 2 be installed in the front-end bearing pedestal 18 and with its axial sliding fit, described rear bearing group 10 is installed in the bearing holder (housing, cover) 3, described bearing holder (housing, cover) 3 is installed in the rear bearing block 19, the screw thread rotation set has a gear ring 7 on the bearing holder (housing, cover) 3, described gear ring 7 and gear shaft 4 engagements, described gear shaft 4 is in transmission connection with reducing motor 5, and described gear ring 7 is axially fixed in the rear bearing block 19, and described bearing holder (housing, cover) 3 circumferentially is fixed in the rear bearing block 19.Wherein, described bearing holder (housing, cover) 3 circumferentially is fixed in the rear bearing block 19 by key 8, and the described rear end of smoothing roll 9 down is connected with displacement transducer 6, and displacement transducer 6 is connected with display unit.
