According to technical scheme provided by the invention: tapered cylinder cylindrical shell rolling device, comprise the veneer reeling machine top working roll, veneer reeling machine top working roll left end is bearing in veneer reeling machine and touches the pillow in the body; It is characterized in that: also comprise volume conic tube, rolling bearing assembly, friction key and positioning key, the volume conic tube is installed in the left end of veneer reeling machine top working roll by the rolling bearing assembly, offer and be parallel to its axial keyway on the outer wall of volume conic tube, positioning key and friction key are installed in the keyway of volume conic tube; Described positioning key left end is provided with protuberance, and the described veneer reeling machine body of touching the pillow is provided with locating slot with this protuberance corresponding matching, and protuberance inserts in the locating slot, to prevent that rolling up conic tube follows the rotation of veneer reeling machine top working roll; Described friction key right-hand member is provided with the portion of exposing, and this portion of exposing is used for providing frictional resistance to fanning strip.
As a further improvement on the present invention, described rolling bearing assembly comprises thrust ball bearing, back-up ring and snap ring, thrust ball bearing and shield ring sleeve on the axle journal of veneer reeling machine top working roll and be loaded on the volume conic tube in, thrust ball bearing one side is withstood on the volume conic tube, the thrust ball bearing opposite side blocks by back-up ring, back-up ring is spacing by the snap ring that is installed on the veneer reeling machine top working roll, is connected with screw between back-up ring and the snap ring.
As a further improvement on the present invention, described positioning key and friction key all are to be installed in the keyway of volume conic tube by the mode of attachment screw with movable dismounting.
As a further improvement on the present invention, between described volume conic tube and the veneer reeling machine top working roll composite bush is housed also.
The present invention compared with prior art, advantage is: (1) is installed on the veneer reeling machine top working roll owing to friction key, when rolling (except during pre-bending) veneer reeling machine top working roll all the time with two bottom working roll symmetries, so no matter which bottom working roll the fanning strip end moves to, its fulcrum is all the time at the medium position of friction key, make and the accurate positioning of fanning strip on veneer reeling machine improved the precision that rolls cylindrical shell.(2) because the frictional resistance of fanning strip is provided by friction key, the friction key volume is little, make simple and cost low, friction key can make things convenient for fast and change during because of wear out failure, can improve production efficiency of equipment, has reduced manufacturing cost and maintenance cost.

The specific embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As Fig. 2 ~ shown in Figure 4, veneer reeling machine top working roll 3 left ends are bearing in veneer reeling machine and touch the pillow in the body 13, volume conic tube 8 is installed in the left end of veneer reeling machine top working roll 3 by the rolling bearing assembly, on the outer wall of volume conic tube 8, offer and be parallel to its axial keyway 8a, positioning key 12 and friction key 10 are installed in the keyway 8a of volume conic tube 8 by attachment screw 11 respectively, positioning key 12 and friction key 10 movable dismountings; Described positioning key 12 left ends are provided with protuberance 12a, and the described veneer reeling machine body 13 of touching the pillow is provided with locating slot 13a with this protuberance 12a corresponding matching, and protuberance 12a inserts in the locating slot 13a, to prevent that rolling up conic tube 8 follows 3 rotations of veneer reeling machine top working roll; Described friction key 10 right-hand members are provided with and expose the 10a of portion, and this exposes the 10a of portion and is used for providing frictional resistance to fanning strip.
As shown in Figure 2, described rolling bearing assembly comprises thrust ball bearing 7, back-up ring 6 and snap ring 5, thrust ball bearing 7 and back-up ring 6 are enclosed within on the axle journal of veneer reeling machine top working roll 3 and are loaded in the volume conic tube 8, thrust ball bearing 7 one sides are withstood on the volume conic tube 8, thrust ball bearing 7 opposite sides block by back-up ring 6, back-up ring 6 is spacing by the snap ring 5 that is installed on the veneer reeling machine top working roll 3, is connected with screw between back-up ring 6 and the snap ring 5.In addition, between described volume conic tube 8 and the veneer reeling machine top working roll 3 composite bush 9 is housed also, composite bush 9 has that coefficient of friction is little, wear-resisting, corrosion resistance is good and the characteristics of oil-free lubrication, and volume conic tube 8 can be rotated on veneer reeling machine top working roll 3 more neatly.
During concrete work, as shown in Figure 5, with the fanning strip small end near friction key 10, reduce the translational speed of fanning strip small end by the frictional resistance of friction key 10, the big small end that makes fanning strip is along with the rotation of veneer reeling machine top working roll 3 and two bottom working rolls 4 is moved simultaneously, thereby rolls out the tapered cylinder cylindrical shell.
Because friction key 10 is installed on the veneer reeling machine top working roll 3, and when rolling [except during pre-bending] veneer reeling machine top working roll 3 all the time with two bottom working roll 4 symmetries, the fulcrum of fanning strip is all the time at the middle part of friction key 10, make the accurate positioning of fanning strip on veneer reeling machine, thereby improved the precision that rolls cylindrical shell.And because the frictional resistance of fanning strip is to be provided by friction key 10, friction key 10 volumes are little, make simple and cost low, friction key 10 can make things convenient for fast and change during because of wear out failure, can improve production efficiency of equipment, has reduced manufacturing cost and maintenance cost.
