Abstract
The utility model relates to a four piece type large expansion and contraction volume decoiler roller, which comprises a main transmission shaft (6). The interior of the main shaft is quadrate, and gear racks are arranged on four surfaces of the main shaft. A sliding plate (3) is fixed on the end surface of the main transmission shaft, and an arc block (1) is fixedly connected with a positioning pin (8) and sliding gear racks (2) through screw bolts. A transmission device of the main shaft is connected with a revolution hydraulic oil cylinder installed at the tail through the back end of a push rod (7), and shaft moving gear racks are arranged in an advancing shaft direction of the push rod and is engaged with gear wheels (4) arranged in the push rod. The gear wheels of a gear wheel group are engaged with the gear racks (2) which move in a horizontal direction, and the gear racks (2) move outwards under the action of the sliding plate (3). The decoiler roller saves equipment investment and reduces land occupying area.
Description
Technical field:
The utility model relates to the architecture advances technical field of copper strips roughing mill reel of uncoiler, a kind of fFour piece type large expansion and contraction volume reel of uncoiler.
Background technology:
The copper strips calendering is produced wide in variety, little in batches, therefore adopt single chassis multi-pass reversible rolling usually, the varied in thickness scope of the rolled strip of milling train is big, be rolled down to 0.5mm by 16mm, divide several rolling processes to finish, necessary annealing in process after each rolling process, therefore and then uncoiling is rolling, finishes wholely rollingly must implement repeatedly uncoiling to the band of different-thickness.
Because the roughing mill supplied materials supplies base by hot-rolling mill and horizontal casting, its taking-up equipment is three roller coiling machines, so its coiled material internal diameter is a variable quantity, is generally φ 500mm～φ 800mm, and independent thick band uncoiling case is set, and this form uncoiling case is no tension force uncoiler; Other strip uncoiler is adopted in later uncoiling, and a unit needs the uncoiler of two different purposes, and this form uncoiler is subjected to structural limitations, and the breathing amount of reel is generally about 40mm, and maximum is no more than 150mm.Therefore unit equipment is heavy, and floor space is big, and investment is high.
Summary of the invention:
The purpose of this utility model provides a kind of fFour piece type large expansion and contraction volume reel of uncoiler, adapts to the roll coil of strip uncoiling of thick band of the various bands of roughing mill and different coil diameters, makes it the simplified apparatus structure, and the few floor space of letter is saved cost of investment.
The utility model adopts following technical scheme to realize the foregoing invention purpose:
Described fFour piece type large expansion and contraction volume reel of uncoiler, it has a final drive shaft, is square shape in the main shaft, and four faces respectively are provided with tooth bar; One end face of final drive shaft is fixed with sliding panel, and secter pat fixes with sliding rack with alignment pin by bolt and connects; The transmission device of main shaft is connected with the revolution hydraulic jack that is installed in afterbody by the rear end of tooth bar push rod, push rod advances also to be provided with on the axial direction and moves axially tooth bar, axially tooth bar is meshed with the gear that is arranged on inside, the gear of gear train and the tooth bar engagement of laterally moving, tooth bar outwards moves under slide plate guiding, four secter pats are expanded outwardly and shrinks.
Described fFour piece type large expansion and contraction volume reel of uncoiler, its gear, tooth bar are the straight-tooth profile of tooth.
Owing to adopted technical scheme as mentioned above, the utlity model has following good effect:
The utility model has adopted the fFour piece type secter pat with gear one tooth bar transmission, realizes the large expansion and contraction volume uncoiling, need not to adopt the uncoiler of two different purposes, has saved equipment investment, has reduced floor space.
The utility model reel breathing scope φ 470mm～φ 850mm can adapt to the coiled material of various internal diameters.Especially be applicable to the roughing mill uncoiling.
The maximum uncoiling tension 40KN of the utility model adapts to the strap tension uncoiling of different-thickness.
The narrow material single drum of its coiled material of the utility model; Wide material can be with two reels, to satisfy the demand.
The drawing explanation:
Fig. 1 is a fFour piece type large expansion and contraction volume reel of uncoiler overall structure schematic diagram:
As shown in fig. 1: 1-secter pat, 2-tooth bar, 3-slide plate, 4-gear, 5-holder, 6-main shaft, 7-tooth bar push rod, 8-alignment pin, 9-baffle ring.
The specific embodiment:
As shown in fig. 1, this fFour piece type large expansion and contraction volume reel of uncoiler, it has a final drive shaft (6), is the square shape in the main shaft, and four faces respectively are provided with tooth bar; The front end face of final drive shaft is fixed with sliding panel (3), and four secter pats (1) constitute the reel of uncoiler, and secter pat fixes with sliding rack (2) with alignment pin (8) by bolt and connects; The transmission of main shaft is promoted by push rod (7) and the revolution hydraulic jack that is installed in afterbody, also be provided with axial tooth bar on the push rod direction of advance, axially tooth bar is meshed with the gear that is arranged on inside, the engagement of gear train drives the upwards expansion of tooth bar (2) of laterally moving, tooth bar (2) is outwards mobile down in slide plate (3) guiding, four secter pats are expanded outwardly and shrinks.Position shown in the figure is the retracted position of reel.During spreading, push rod (7) is promoted left by hydraulic cylinder, and driven gear rotation, tooth bar (2) outwards move secter pat (1) spreading.Because of the stroke of push rod (7) is not subjected to structural limitations substantially, it is very big that secter pat can increase, and realizes the uncoiling of big harmomegathus amount.
Claims (2)
1, a kind of fFour piece type large expansion and contraction volume reel of uncoiler is characterized in that: described reel of uncoiler, and it has a final drive shaft (6), is square shape in the main shaft, and four faces respectively are provided with tooth bar; One end face of final drive shaft is fixed with sliding panel (3), and secter pat (1) fixes with sliding rack (2) with alignment pin (8) by bolt and connects; The transmission device of main shaft is connected with the revolution hydraulic jack that is installed in afterbody by the rear end of tooth bar push rod (7), push rod advances also to be provided with on the axial direction and moves axially tooth bar, axially tooth bar is meshed with the gear (4) that is arranged on inside, the gear of gear train and tooth bar (2) engagement of laterally moving, tooth bar (2) outwards moves under slide plate (3) guiding.
2, fFour piece type large expansion and contraction volume reel of uncoiler as claimed in claim 1, it is characterized in that: the gear of described reel of uncoiler (4), tooth bar are the straight-tooth profile of tooth.
