Abstract
The utility model provides a guide plate regulating device for a rolling mill, which comprises a trunnion seat, a hinge pin, a lifting lug, a connecting chain, a regulating screw, a lifting lug support, a cantilever hinge pin, a regulating nut, a revolving wheel disc and the like. The combination modes are as follows: the revolving wheel disc and the regulating screw and nut are assembled together, the cantilever hinge pin is mounted in the lifting lug support, the regulating screw, the connecting chain and the lifting lug are welded integrally, the upper part of the welded integration regulates the screw spline position to cooperate with the cantilever hinge pin spline groove and is fixed by the regulating nut, and the lower part lifting lug is fixed with the trunnion seat by the hinge pin. The application of the guide plate regulating device can realize the accurate regulation of the medium guide plate for a rolling mill, effectively avoid the friction between the guide plate and the roller surface, reduce the roller wear and the consumption of the rolling mill guide plate spare parts, prolong the service life of equipment, fundamentally solve the problems, such as the serious wear of the roller surface, the poor quality of the steel plate surface, the frequent replacement of the rolling mill guide plate and the like, and ensure the steel plate rolling smoothly.
Description
Technical field
The utility model belongs to milling train mill auxiliaries equipment, particularly a kind of adjusting device of heavy and medium plate mill guide plate.
Background technology
On the Medium and Heavy Plate Rolling Production line, guide plate is one of requisite mill auxiliaries equipment of milling train.The main effect of guide plate is can alleviate the impact of rolled plate breaker roll working roll greatly and guarantee nipping smoothly of steel plate, guarantees that the stable of steel plate rolling process carries out.Last high-pressure water descaling utmost point pipe with steel plate places in the guide plate simultaneously, to avoid the possibility of steel plate bump high pressure water electrode pipe.
Existing rolling mill guide generally has two kinds of versions: a kind of form is the little guide plate of design and installation on operation roll of mill, adjust when the assembly work roller in advance on request in the gap of guide plate and roller surface, and rolling mill guide contacts by the little guide plate on hydraulic motor adjustment and the working roll.Its weak point is, because the guide plate structure more complicated is thiner again, be difficult to again adjust with the gap of little guide plate on the milling train, rolling thickness during less than the steel plate of 6mm fault rate higher, and the manufacturing expense of complete equipment is very big, can not satisfy the actual needs of producing fully; Another kind of form is that guide plate is fixed on the milling train balladeur train, and at guide plate and roll contact position installation scraper plate, guide plate relies on deadweight (about about 6 tons) directly to be pressed against on the roller surface by scraper plate, cause guide plate and roll to contact pressure quite big, it is also very serious to wear and tear, and needs frequent operation roll of mill and the guide plate changed.Guide plate replacement cycle average out to one month, wearing and tearing thickness reaches about 30mm when changing at every turn.In addition,, influenced the surface quality of steel plate greatly, can not meet the needs of production and the quality requirement of user surface of steel plate because the roller surface serious wear causes surface of steel plate that the cut impression is arranged.
The problem that descends for the serious wear that solves roller surface and consequent plate quality, once attempted middle board assembly line integral body is transformed into plate production line guide plate structure form, but owing to be subjected to spatial constraints, huge and the fluctuation of service of change amount, the accident that steel plate creeps into guide plate repeatedly takes place in the actual motion of slab line, may cause a series of device damage thus, cause enormous economic loss.
Summary of the invention
The purpose of this utility model is the deficiency that exists at above-mentioned prior art, and a kind of rolling mill guide adjusting device is provided.Use this device and can realize the accurate adjustment of heavy and medium plate mill guide plate, effectively avoid the friction of guide plate and roller surface, improve plate surface quality, reduce the consumption of roll wear and rolling mill guide spare part, the service life of prolongation equipment, fundamentally solved owing to roller surface serious wear, plate surface quality difference and rolling mill guide that guide plate and contacting of roll produce are changed a series of problems such as frequent, guaranteed carrying out smoothly of steel plate rolling.
The utility model is to be made of parts such as trunnion base, bearing pin, hanger, chain, adjustment screw, hanger bearing, cantilever bearing pin, adjustment nut, rotation roulettes.Concrete compound mode is, rotation roulette and adjusting screw are assembled together, the cantilever bearing pin is installed in the hanger bearing, adjusting screw, connection chain and hanger is welded as a whole, top is adjusted screw spline position and is cooperated with cantilever bearing pin spline, and fix with the adjustment nut, the bottom hanger aligns with trunnion base, fixes with bearing pin.
The utility model has overcome the deficiencies in the prior art, has following advantage:
1. prolonged the service life of guide plate and roll, the replacement cycle of guide plate extended to 8 by 1 month; Roll is by changing 6 former every day to improving the replacing of average two classes in back once.
2. effectively avoid contacting of guide plate and work roll surface, prevented the wearing and tearing of guide plate and roller surface, improved the surface quality of steel plate greatly.
3. alleviate steel plate to the impact of operation roll of mill and nipping smoothly of assurance steel plate, guarantee carrying out smoothly of steel plate rolling process.
Description of drawings
Accompanying drawing is a rolling mill guide adjusting device structural representation
Among the figure: trunnion base 1, bearing pin 2, hanger 3, connection chain 4, adjustment screw 5, hanger bearing 6, cantilever bearing pin 7, adjustment nut 8, rotation roulette 9.
The specific embodiment
Below in conjunction with the embodiment in the accompanying drawing the utility model is described in detail: as shown in the figure, the rolling mill guide adjusting device is to be made of trunnion base 1, bearing pin 2, hanger 3, connection chain 4, adjustment screw 5, hanger bearing 6, cantilever bearing pin 7, adjustment nut 8, rotation roulette 9.Wherein: adjusting screw 5 bottoms is the homalocephalus shape, and the centre is a spline, and top is screw thread; Cantilever bearing pin 7 both sides are respectively axle and homalocephalus, are spline in homalocephalus; Adjusting nut 8 tops is screw structural, and the bottom is the axle sleeve shape, with the not frayed destruction of protection adjusting device stroke range internal thread; Above parts all adopt the 1Cr18Ni9Ti material.
Concrete compound mode: rotation roulette 9 and adjustment nut 8 are assembled together; Cantilever bearing pin 7 is installed in the hanger bearing 6; Adjust screw 5, connection chain 4 and hanger 3 and be welded as a whole, the whole top after the welding is adjusted screw spline position and is cooperated with cantilever bearing pin 7 splines, and fixing with adjusting nut 8; Bottom hanger 3 aligns with trunnion base 1, and penetrate in the hole with bearing pin 2 and fix, and fastening with the M36 nut.
During installation, engaging lug axle bed 1 is welded on the suitable position of guide plate, adjusting device bearing centering welding is fixedly on the balladeur train of milling train front and back, hanging hydraulic cylinder by guide plate when changing jobs roller lifts guide plate, extract working roll out, by rotation roulette 9 guide plate is adjusted nut 8 and be screwed to adjustment screw 5 outer ends, guide plate descends then, this moment, the elongation of adjusting device will guarantee that guide plate contacts with the surface of roll working roll, adjusting nut 8 tightens, guide plate is lifted, be screwed into 360 degree behind the nut screwing clamping of both sides again, put down guide plate, check the gap of guide plate and roller surface, the big I in concrete gap is determined according to actual conditions, is as the criterion to guarantee that steel plate can not pierce between guide plate and the working roll.
