Description
Technical field
The invention belongs to milling train operation field, is that a kind of three-roller type is stablized the roller mounting mechanism.
Background technology
In the cold-rolling mill production line, also have a segment distance owing between band is from the entrance to the mill roll-gap, band can produce in this zone to be shaken, thereby influences the precision of aspects such as thickness measure.
To this phenomenon, domestic present processing method one: as far as possible shorten the distance between milling train and the entrance; The secondth, adopt the double-roller type pinch roll.First method is because entrance has multiple devices such as oil removing and side be thick, and it is very limited to reduce the distance; Though first method can to a certain degree be improved the band shake, does not still cause the shake of band to eliminate because the supplied materials template is good, thereby causes the inaccurate problem in thickness measure position.
Summary of the invention
The objective of the invention is to stablize the roller mounting mechanism for the cold-rolling mill production line provides a kind of use, the safe and reliable three-roller type of performance, this device well combines hydraulic technique and frame for movement.
Technical scheme of the present invention is that three-roller type is stablized the roller mounting mechanism; Which comprises at least two fixedly roller, up-down roller, guide plate, support body, lift cylinders, locking cylinder, near switch and lazy-tongs; Two fixedly roller be separately fixed at the right ends of support body; The up-down roller is fixed in the middle of the support body, is fixedly connected through axle with lift cylinders; Locking cylinder is fixedly connected with axle, it is characterized in that: below the up-down roller, locking cylinder is arranged, and orthogonal; Lift cylinders and locking cylinder are equipped with near switch respectively, and are connected into electric-control system; Lazy-tongs are fixed on the support body; Up-down roller decline state, the connecting axle pin joint of the connecting axle of locking cylinder and lift cylinders, locking cylinder pins lift cylinders.
Described up-down roller is than the position protrusion of fixing rod, two fixedly rods and up-down roller formation " protruding " type.
Described lazy-tongs are pinion and racks.
Described up-down roller decline state, band fixedly forms the serpentine curve in the middle of roller roller and the up-down roller at two.
Described lift cylinders and locking cylinder are hydraulic jacks.
Characteristics of the present invention be have safe and reliable, compact conformation, functional, convenience operation can be used in the various cold-rolling mill production lines; This device well combines hydraulic technique and frame for movement.This device has been successfully applied in the cold-rolling mill production line.
Description of drawings
To combine embodiment that the present invention is further described below:
Fig. 1 is the structural representation of three-roller type roller stabilizing apparatus.
Among the figure: 1, fixing roller; 2, up-down roller; 3, near switch; 4, locking cylinder; 5, lift cylinders; 6, guide plate; 7, support body; 8, lazy-tongs.
The specific embodiment
Embodiment: as shown in Figure 1; Three-roller type is stablized roller mechanism; Which comprises at least two fixedly roller 1, up-down roller 2, guide plate 6, support body 7, lift cylinders 5, locking cylinder 4, near switch 3 and lazy-tongs 8; Two fixedly roller 1 be separately fixed at the right ends of support body 7, up-down roller 2 is fixed in the middle of the support body 7, with lift cylinders 5 through spool being fixedly connected; Locking cylinder 4 is fixedly connected with axle, and up-down roller 2 is connected with guide plate 6; Locking cylinder 4 is arranged below up-down roller 2, and orthogonal; Lift cylinders 5 is equipped with respectively near switch 3 with locking cylinder 4, and is connected into electric-control system; Lazy-tongs are fixed on the support body; Up-down roller decline state, the connecting axle pin joint of the connecting axle of locking cylinder and lift cylinders, locking cylinder pins lift cylinders.
Described up-down roller can be than the position protrusion of fixing rod, two fixedly rods and up-down roller formation " protruding " type.The front end the right and left that is support body 7 respectively is fixed with a fixedly rod 1, and a up-down roller 2 is housed in the middle of the support body 7, and protrude than fixing rod 1 position of up-down roller 2, two fixedly rod 1 and up-down roller 2 formation " protruding " shapes.Lazy-tongs 8 can be pinion and racks, also are fixed on the support body 7, play synchronous effect.
Up-down roller 2 is connected with guide plate 6, and the roller 2 that goes up and down simultaneously is fixedly connected with 5 of lift cylinders.
Locking cylinder 4 is positioned at up-down roller 2 belows, and locking cylinder 4 also is fixedly connected with axle.Locking cylinder 4 can all be a hydraulic jack with lift cylinders 5, and is orthogonal with their axle that is fixedly connected.Locking cylinder 4 all is equipped with near switch 3 with lift cylinders 5, and is connected into electric-control system, has realized the interlocked control of technology, and has guaranteed the safety of the person and equipment.
When lift cylinders 5 drive up-down rollers 2 dropped to predeterminated position, locking cylinder 4 work were locked when connecing the realization duty through two pivot pins, have prevented the deviation that up-down roller 2 causes down in working order.Up-down roller 2 decline states, band fixedly forms the serpentine curve in the middle of roller roller and the up-down roller at two, and the serpentine curve has played the effect of stabilising strip.
When off working state, locking cylinder 4 is opened, and lift cylinders 5 drives up-down roller 2 and lifts, and has made things convenient for to wear band and detect maintenance.
It should be noted that well-known components and common structure or conventional means that parts that present embodiment is not described in detail and structure belong to the industry, here narration one by one.
