Description
Technical field
The smooth roller that the present invention relates to the planisher in metallurgical the smelting is safeguarded auxiliary equipment, particularly a kind of device that changes smooth roller roll change guide groove position.
Background technology
Thin size hot-rolled plate plate shape needs smooth unit to carry out the plate face, and smooth just to reach the user required, so existing hot rolling line, all supporting have one four a roller flat line, promptly as shown in Figure 1 and Figure 2, comprise that planisher memorial archway 1, roller are adjusted memorial archway 2, upper support roller 3, lower support roller 4, top working roll 5 and bottom working roll 6 and shockproof roller 7, depressed screw mandrel 8, grinding and polishing electro-optical device 9 and band-type brake 10 up and down.(400m～500m/min), smooth working roller abrasion is fast, the replacement cycle short (average 2～3 days more transducer set) because smooth unit speed of production is fast.Therefore, for smooth unit, all set up a cover work roll changing mechanism, so that in time change the working roll that is worn.Existing roll change mechanism as shown in Figure 1 and Figure 2, be to adjust fixed installation four roll change guide grooves, i.e. top working roll entrance side roll change guide groove 21, top working roll outlet side roll change guide groove 22, bottom working roll entrance side roll change guide groove 23 and bottom working roll outlet side roll change guide groove 24 on the memorial archway 2 in roller.Each roll change guide groove is installed in roller by bolted respectively and adjusts on the memorial archway 2.Press guide groove distributing position and production actual conditions for many years; overslaugh flat line ordinary production be top working roll entrance side roll change guide groove 21; this guide groove is that smooth steel band height has only 60mm between upper working rolls and lower working rolls; be easy to be drawn guide groove bad by the steel band afterbody; in case draw bad; will shut down repairing, become one of principal element of puzzlement flat line production.
A kind of technology is abroad arranged, four roller planisher roll change guide grooves are contained in the pre-changing rig of planisher driving side the inside, by four hydraulic cylinder controls, when needs are changed working roll, four hydraulic cylinders are released four guide grooves and are connected with the active side roll change buggy, the pre-changing rig of driving side is released working roll along the guide groove roll change then, and roll change finishes, and guide groove is recovered to pre-changing rig the inside by hydraulic cylinder.This device has two defectives, and first: the pre-changing rig equipment of driving side is huge, and the guide groove position of putting of living forever more is big more.Second: do not have guiding device because of guide groove in the oversize and butt joint, need are docked by artificial help when releasing guide groove and being connected with roll change buggy.
In a word, the problem of prior art roll change mechanism existence is:
1, since the roll change guide groove to bear the sliding surface of working roll gravity narrow, make the guide groove cross section produce oblique reaction of bearing, because of guide groove be subjected to gravity after guide groove oblique to gravity one square neck, what be subjected to oblique reaction of bearing at last is the guide groove bolt that is fastened on the roller adjustment memorial archway, easily the guide groove bolt is broken.
2, it is necessary in the production technology changing the planisher working roll, and roll change must have guide groove to carry out transition, because being the height of smooth steel band, the installation site of top working roll entrance side roll change guide groove has only 60mm between double-working, steel band nose head in the production and folding, sideslip afterbody are easy to guide groove is drawn bad, directly influence the flat line ordinary production.
3, roller is adjusted memorial archway does not have safeguard procedures, reason is, the roll change guide groove is installed in roller by bolted and adjusts on the memorial archway, in case guide groove is by steel band afterbody stretch bending, the guide groove damaged injures roller simultaneously and adjusts memorial archway, must carry out laid-up or change parts memorial archway, increase workload and maintenance cost.
Summary of the invention
Purpose of the present invention is to solve the problems referred to above that prior art exists, and a kind of device that changes smooth roller roll change guide groove position is provided.
The object of the present invention is achieved like this: a kind of device that changes smooth roller roll change guide groove position, comprise top working roll entrance side roll change guide groove, top working roll outlet side roll change guide groove, bottom working roll entrance side roll change guide groove and bottom working roll outlet side roll change guide groove, also comprise oblique two and half arc rail plates and two hydraulic drive mechanisms that are arranged on the planisher entrance side, the lower end of two and half arc rail plates is installed in roller respectively and adjusts on the memorial archway, the upper end is installed in respectively on the planisher memorial archway, described top working roll entrance side roll change guide groove is inlaid between the two and half arc rail plates, the stiff end of two hydraulic drive mechanisms is connected on the planisher memorial archway, and its movable end is connected to the two ends of top working roll entrance side roll change guide groove and can drives top working roll entrance side roll change guide groove and moves up and down along two and half arc rail plates.
Described two and half arc rail plates are two identical groove shape structural members of symmetrical configuration, its groove is half arc, constitute the slideway of top working roll entrance side roll change guide groove, one end of groove outwards connects, other end sealing also has the suitable structure in end with top working roll entrance side roll change guide groove, constitutes the fixed mount of top working roll entrance side roll change guide groove.
Described two hydraulic drive mechanisms respectively comprise a hydraulic cylinder, a cylinder seat, a backing plate and a piston rod bearing, backing plate is installed on the planisher memorial archway, the cylinder seat is installed on the backing plate, the cylinder body of hydraulic cylinder is installed on the cylinder seat, the outer end of the piston rod of hydraulic cylinder is installed on the piston rod bearing, and the piston rod bearing is fixedly linked with top working roll entrance side roll change guide groove again.
Described two and half arc rail plates are adjusted the end that memorial archway is connected in itself and roller and are respectively equipped with the construction bolt hole, half arc rail plate is adjusted memorial archway by this construction bolt hole and roller and is fixedly linked, two and half arc rail plates are respectively equipped with the installation long slot bore at the end that it is connected with the planisher memorial archway, half arc rail plate is movably connected by this installation long slot bore and planisher memorial archway, when roller adjustment memorial archway was adjusted up and down, half arc rail plate can slide up and down along this long slot bore.
The setting height(from bottom) of described two and half arc rail plates guarantees can not cause collision to guide groove when shockproof roller moves.
The present invention changes the device of smooth roller roll change guide groove position owing to adopted above technical scheme, makes it compared with prior art, has following advantage and characteristics:
1, owing to adopts two and half arc rail plates to be installed on roller adjustment memorial archway and the planisher memorial archway, guide groove slip stress surface and oblique reaction of bearing face are 35 ° of angles, gravity during roll change has half to be absorbed by rail plate, can alleviate the fastening tractive force of bolt.
2, owing to adopt two and half camber rail plates to be fixedly mounted on the roller adjustment memorial archway by original form, the shift in position of guide groove is to decide according to whether changing working roll, guide groove is in the roll change position during roll change, the roll change guide groove that finishes can not rise to and drawn bad position by the steel band afterbody, thereby can guarantee that guide groove can not drawn bad by the steel band afterbody.
