Abstract
The invention discloses a three-roller stable roller mechanism. The three-roller stable roller mechanism at least comprises two fixing rollers, a lifting roller, a guide plate, a frame, a lifting cylinder, a locking cylinder, approach switches, and a synchronization mechanism; the two fixing rollers are fixed at left and right ends of the frame; the lifting roller is fixed in the middle of the frame and is fixedly connected with the lifting cylinder through a shaft; the locking cylinder is fixedly connected with a shaft; the three-roller stable roller mechanism is characterized in that: the lifting roller is connected with a guide plate; the locking cylinder is arranged below the lifting roller, and the lifting roller is vertical to the locking cylinder; each of the lifting cylinder and the locking cylinder is provided with one approach switch and the lifting cylinder and the locking cylinder are connected to an electronic control system; the synchronization mechanism is fixed on the frame; and in the descending state of the lifting roller, a connection shaft of the locking cylinder is in pin joint with a connection shaft of the lifting cylinder; and the locking cylinder locks the lifting cylinder. The mechanism has the characteristics of safety and reliability, compact structure, good performance, and convenience in operation, can be applied to various operation lines of cold rolling mills, integrates a hydraulic technology and a mechanism structure, and is successfully applied to the operation line of the cold rolling machine.
Description
Technical field
The invention belongs to milling train operation field, is a kind of three-roller type stabilizing roller mounting mechanism.
Background technology
In cold-rolling mill production line, owing to also having a segment distance between band is from entrance to mill roll-gap, band can produce shake in this region, thereby affects the precision of the aspects such as thickness measure.
To this phenomenon, domestic current processing method one: as far as possible shorten the distance between milling train and entrance; The secondth, adopt double-roller type pinch roll.First method, because entrance has oil removing and the multiple devices such as side is thick, reduces the distance very limited; Though first method can to a certain degree be improved band shake, still causes the shake of band to eliminate, thereby cause the inaccurate problem in thickness measure position because supplied materials template is not good.
Summary of the invention
The object of the invention is for cold-rolling mill production line provides a kind of use, the reliable three-roller type stabilizing roller of performance safety mounting mechanism, this device well combines hydraulic technique and frame for movement.
Technical scheme of the present invention is three-roller type stabilizing roller mounting mechanism, which comprises at least two fixing rollers, lifting roller, guide plate, support body, lift cylinders, locking cylinder, approach switch and lazy-tongs, two fixing rollers are separately fixed at the two ends, left and right of support body, lifting roller is fixed in the middle of support body, is fixedly connected with by axle with lift cylinders; Locking cylinder is fixedly connected with axle, it is characterized in that: below lifting roller, there is locking cylinder, and orthogonal; Lift cylinders and locking cylinder are equipped with respectively approach switch, and are connected into electric-control system; Lazy-tongs are fixed on support body; Lifting roller decline state, the connecting axle pin joint of the connecting axle of locking cylinder and lift cylinders, locking cylinder pins lift cylinders.
Described lifting roller protrudes than the position of fixing rod, and two fixing rods and a lifting roller form " protruding " type.
Described lazy-tongs are pinion and racks.
Described lifting roller decline state, band forms serpentine curve in the middle of two fixing roller rollers and a lifting roller.
Described lift cylinders and locking cylinder are hydraulic jacks.
Feature of the present invention be have safe and reliable, compact conformation, functional, easy to operate feature, can be used in various cold-rolling mill production lines; This device well combines hydraulic technique and frame for movement.This device has been successfully applied in cold-rolling mill production line.
Accompanying drawing explanation
Below in conjunction with embodiment, the present invention is further illustrated:
Fig. 1 is the structural representation of three-roller type roller stabilizing apparatus.
In figure: 1, fixing roller; 2, lifting roller; 3, approach 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 stable roller mechanism, which comprises at least two fixing rollers 1, lifting roller 2, guide plate 6, support body 7, lift cylinders 5, locking cylinder 4, approach switch 3 and lazy-tongs 8, two fixing rollers 1 are separately fixed at the two ends, left and right of support body 7, lifting roller 2 is fixed in the middle of support body 7, is fixedly connected with by axle with lift cylinders 5; Locking cylinder 4 is fixedly connected with axle, and lifting roller 2 is connected with guide plate 6; Below lifting roller 2, there is locking cylinder 4, and orthogonal; Lift cylinders 5 and locking cylinder 4 are equipped with respectively approach switch 3, and are connected into electric-control system; Lazy-tongs are fixed on support body; Lifting roller decline state, the connecting axle pin joint of the connecting axle of locking cylinder and lift cylinders, locking cylinder pins lift cylinders.
Described lifting roller can protrude than the position of fixing rod, and two fixing rods and a lifting roller form " protruding " type.The front end the right and left that is support body 7 is respectively fixed with a fixing rod 1, in the middle of support body 7, a lifting roller 2 is housed, and protrude than fixing rod 1 position of lifting roller 2, and two fixing rods 1 and a lifting roller 2 form " protruding " shape.Lazy-tongs 8 can be pinion and racks, are also fixed on support body 7, play synchronous effect.
Lifting roller 2 is connected with guide plate 6, and the roller 2 of lifting is simultaneously fixedly connected with lift cylinders 5 axles.
Locking cylinder 4 is positioned at lifting roller 2 belows, and locking cylinder 4 is also fixedly connected with axle.Locking cylinder 4 and lift cylinders 5 can be all hydraulic jacks, orthogonal with their axle being fixedly connected with.Locking cylinder 4 and lift cylinders 5 are all equipped with approach switch 3, and are connected into electric-control system, have realized the interlocked control of technique, and have guaranteed the safety of the person and equipment.
When lift cylinders 5 drives lifting roller 2 to drop to predeterminated position, locking cylinder 4 is worked, and by two pivot pins, is connect while realizing duty and is locked, and has prevented the deviation that lifting roller 2 causes down in working order.Lifting roller 2 decline states, band forms serpentine curve in the middle of two fixing roller rollers and a lifting roller, and serpentine curve has played the effect of stabilising strip.
When off working state, locking cylinder 4 is opened, and lift cylinders 5 drives lifting roller 2 to lift, and has facilitated threading and has detected maintenance.
It should be noted that parts that the present embodiment does not describe in detail and structure belong to well-known components and common structure or the conventional means of the industry, here not narration one by one.
