Description

A kind of reel

[technical field]

The present invention relates to metal-pressed machine strip production field, especially relate to a kind of be applied to cold rolling, the unit such as hot rolling or straightening uncoiling and devices for taking-up in reel.

[background technology]

Known, in the process of metal-pressed machine strip production operation, particularly when running cold mill complex, hot rolling, withdrawal straightening stands, often to use reel come the uncoiling of sheet material and batched operation, but, along with strip develops to wide cutization, uncoiling during its production operation, coiling tension are also corresponding to be increased a lot, but because existing reel is basic or relative transmitting torque can only be relied on less, the key that reliability is not high carrys out transmitting torque, and therefore its production operation that well can not adapt to wide cut strip again require that.

[summary of the invention]

In order to overcome the deficiency in background technology, the invention discloses a kind of reel that effectively can strengthen transmitting torque.

For achieving the above object, the present invention adopts following technical scheme:

A kind of reel, described reel comprises hollow spindle, fanning strip, radial wedge, guide pillar, mandrel and disc spring group; The outside of described hollow spindle is provided with three pieces of corresponding fanning strips forming reel outside wall surface at least uniformly, and the two ends of every block fanning strip all connect by key is corresponding with the rubbing surface of end cover of hollow spindle respective end; The medial surface of described fanning strip is provided with multiple projection block along the radial equidistant arrangement of hollow spindle, and equal correspondence is provided with a radial wedge between two often adjacent fanning strips, two inclined-planes of this radial wedge are all fixed with the slide block that can slide along the fanning strip edge of correspondence; The medial surface of described radial wedge is provided with the boss along hollow spindle radial projection, and this boss runs through by many correspondences that the guide pillar of hollow spindle axle body is corresponding with the mandrel being positioned at hollow spindle inner chamber to be connected; Hollow spindle is arranged with multiple limited impression engaging the projection block of fanning strip and the boss of radial wedge for correspondence, and fanning strip connects by disc spring group is corresponding with hollow spindle.

Further, the inner of described disc spring group is fixed in the middle part of corresponding limited impression bottom land.

Owing to adopting technical scheme as above, the present invention has following beneficial effect:

Reel structure of the present invention is simple, easy to use; Described reel not only can transmit larger moment of torsion when applying, but also effectively strengthens the rigidity of self, thus improves operating efficiency accordingly, extends service life, for producer adds economic well-being of workers and staff.

[detailed description of the invention]

Can explain the present invention in more detail by the following examples, disclose object of the present invention and be intended to protect all changes and improvements in the scope of the invention, the present invention is not limited to the following examples:

Reel by reference to the accompanying drawings described in 1 ~ 3, described reel comprises hollow spindle 1, fanning strip 2, radial wedge 5, guide pillar 8, mandrel 9 and disc spring group 11; The outside of described hollow spindle 1 is provided with three pieces of corresponding fanning strips 2 forming reel outside wall surface at least uniformly, and the two ends of every block fanning strip 2 all connect by key 3 is corresponding with the rubbing surface of end cover of hollow spindle 1 respective end, namely these lateral surfaces fixing spacing fanning strip 2 by key 3 coordinate the cylinder face forming described reel; Between two often adjacent fanning strips 2, equal correspondence is provided with a radial wedge 5, two inclined-planes of this radial wedge 5 are all fixed with the slide block 6 that can slide along fanning strip 2 edge of correspondence, thus radial wedge 5 moving radially along hollow spindle 1, and when causing fanning strip 2 to make the action of corresponding rise footpath or undergauge, slide block 6 can be utilized effectively to avoid occurring rigid friction between radial wedge 5 and fanning strip 2 simultaneously;

The medial surface of described radial wedge 5 is provided with the boss 7 complying with hollow spindle 1 radial projection, this boss 7 runs through by many correspondences that the guide pillar 8 of hollow spindle 1 axle body is corresponding with the mandrel 9 being positioned at hollow spindle 1 inner chamber to be connected, thus when mandrel 9 is along the axial action of hollow spindle 1, radial wedge 5 can be driven to make along the radial direction of hollow spindle 1 by guide pillar 8 to move radially accordingly, namely rise footpath time, mandrel 9 promotes guide pillar 8, guide pillar 8 promotes fanning strip 2 spreading and forms the footpath state that rises, during undergauge, fanning strip 2 and guide pillar 8 lose the thrust of mandrel 9, fanning strip 2 related guide pillar 8 under the pull-back forces of disc spring group 11 shrinks and forms undergauge state, multiple projection block 4 complying with the radial equidistant arrangement of hollow spindle 1 is provided with at the medium position of fanning strip 2 medial surface, hollow spindle 1 is arranged with multiple for the correspondence engaging projection block 5 of fanning strip 2 and the limited impression 10 of the boss 7 of radial wedge 5, the engaging of limited impression 10 and corresponding projection block 5 and boss 7 namely can be utilized to ensure that fanning strip 2 and radial wedge 5 position when movement there will not be deviation, in addition, described fanning strip 2 connects by disc spring group 11 is corresponding with hollow spindle 1, the inner of this disc spring group 11 is fixed in the middle part of the corresponding limited impression 10 of hollow spindle 1, thus can, when radial wedge 5 radially draws in, utilize disc spring group 11 to ensure the effective undergauge of fanning strip 2.

Described reel operationally, because fanning strip 2 utilizes multiple evenly distributed projection block 4 to be inserted in the corresponding limited impression 10 of hollow spindle 1, and also have key 3 role at fanning strip 2 two ends, therefore compared with existing reel, described reel can effectively transmit larger moment of torsion; In addition, described reel when fanning strip 2 proper circle does not increase, effectively can be strengthened the rigidity of reel by being done more by the sectional area of hollow spindle 1, thus extends the service life of reel accordingly.

Part not in the detailed description of the invention is prior art, therefore the present invention is not described in detail.
