Abstract
The invention discloses a large-expansion/retraction drum based on a strip decoiler, which comprises a spindle and a hydraulic cylinder, wherein the spindle is T-shaped, and is supported on a tank body of the decoiler and connected with the hydraulic cylinder by a pressing sleeve and a cylinder seat; the spindle is internally provided with a cavity; a mandrel is arranged in the cavity, and one end of the mandrel is connected with a cylinder lever. The large-expansion/retraction drum is characterized in that the section of the hydraulic cylinder close to the other end of the mandrel is quadrangular; each prismatic surface is provided with racks; a T-shaped spindle nose is arranged at the front end of the spindle and provided with a cross T-shaped groove at the end so as to form 4 symmetrical groove bodies, wherein each groove body is internally provided with 4 gear boxes, and the gear boxes are fixed on the T-shaped spindle nose; a gear I, a gear II and an idler pulley are arranged in each gear box, wherein the gear II is meshed with the racks on the mandrel, and the gear I is meshed with the racks embedded in the T-shaped grooves and fixed on a sector plate; and under the action of the hydraulic cylinder, the sector plate is driven by a rack-gear-idler pulley-gear-rack mechanism to move radially and synchronously.
Description
Technical field
The present invention relates to rolling-in, coiling or the uncoiling of metal or other flexible metallic material, relate in particular to distensible or contractile reel, be used for the expansion of non-ferrous metal and alloy thin band roll coil of strip when rolling.
Background technology
Traditional strip uncoiler, its reel generally adopt pyramid wedge hydraulic pressure harmomegathus structure, use hydraulic cylinder push-and-pull pyramid axle, and the fanning strip that drives reel radially moves, and reaches the purpose of reel harmomegathus.Because be subjected to the restriction of inclined-plane condition of self-locking, the harmomegathus amount of reel is less, usually within 50mm.For the volume core is not the very regular roll coil of strip, especially non-ferrous metal industry adopts centreless to batch the roll coil of strip of formation, its internal diameter varies scope is many more than 200mm, when cold rolling if adopt the reel of pyramid wedge harmomegathus, then its again during uncoiling the roll coil of strip be set to just unusual difficulty of reel.Therefore, pyramid wedge hydraulic pressure harmomegathus structure of the prior art is improved, just seemed especially important.
Summary of the invention
Proposition of the present invention is intended to the uncoiler of the employing pyramid wedge hydraulic pressure harmomegathus structure of prior art is improved, and designs a kind of big harmomegathus amount reel based on gear-rackwork, is used for the expansion of the roll coil of strip that the non-ferrous metal industry centreless batches.
Technical solution of the present invention is achieved in that
A kind of big harmomegathus amount reel based on strip uncoiler, comprise main shaft and hydraulic cylinder, wherein main shaft is the T type, be supported on the uncoiler casing, and overlap II and be connected, in the described main shaft cavity is arranged with hydraulic cylinder by meeting cover I and connecing, axle is wherein arranged, the one end is connected with the cylinder bar, it is characterized in that: the cross section near the axle other end is a quadrangular, all has tooth bar on each prismatic surface; The front end of main shaft is a T oblique crank Z head, and its axle head has the T-slot of right-angled intersection, forms 4 cell bodies of symmetry one by one, and 4 gear housings wherein are housed respectively, and gear housing is fixed on the T oblique crank Z head; Gear I, gear II and idle pulley all are housed in each gear housing, the engagement of gear II wherein and the tooth bar on the axle, another gear I then is embedded in the T-slot with iron chains and the tooth bar that is fixed on the fanning strip is meshed; Under the effect of hydraulic cylinder, promptly drive fanning strip and do synchronous radial motion by rack and wheel-idle pulley-gear-rackwork.
Cover in the gear all is housed in described gear and the idle pulley, and is bearing on the gear-box by gear spindle.
Compared with prior art, advantage of the present invention is apparent, mainly shows:
For the volume core is not the very regular roll coil of strip, especially batches the roll coil of strip of formation with centreless, because of its internal diameter varies is many about 200mm, when cold rolling if adopt the reel of pyramid wedge harmomegathus, its cover volume unusual difficulty just during uncoiling more then.Adopt the big harmomegathus amount reel of rack-and-pinion harmomegathus structure, reel harmomegathus amount can reach 400mm, both can solve above-mentioned uncoiling problem.
