Abstract
The utility model discloses an oval winding drum which comprises a hollow shaft, sector plates, pyramid shafts and copper plungers, wherein the four sector plates are uniformly distributed on the periphery of the hollow shaft, the copper plungers penetrate through positioning holes in the hollow shaft and connect the sector plates and the pyramid shafts, a T-shaped flange is arranged at the top of each copper plunger and matched with a T-shaped groove of each sector plate, the bottom of the copper plunger is an inclined table board, the vertical section of the inclined table board is a T-shaped flange which is matched with a T-shaped groove of the inclined table board on each pyramid shaft, the copper plungers can slide radially under the action of the inclined table boards of the pyramid shafts, the contour of each sector plate is oval, and the four sector plates form a complete oval rotation body. According to the oval winding drum, the oval sector plates are adopted, and the middle of the winding drum is bulged, so that the effective abrasion loss of the winding drum can be increased, and the service life can be prolonged; and meanwhile, the alignment performance of the oval winding drum is good, strip steel deviation during winding can be reduced, and neatness of strip steel edges is facilitated.
Description
Technical field
The utility model belongs to metallurgical steel rolling equipment technical field, is specifically related to a kind of oval reel.
Background technology
Coiling machine is extremely important equipment on output strip line, and how are their structure, operation conditions, not only directly affect unit production efficiency, and closely related with belt steel product quality.Relevant statistics shows, coiling machine fault rate accounts for the over half of production line, and the fault rate of reel account for wherein 2/3.Existing coiler mandrel has adopted cylindrical structural conventionally, and it is simple in structure, easy to manufacture, is widely used on many production lines.But there are following two problems in hot rolling downcoiler reel: the one, be subject to Effect of Hyperthermic Environment, when reel work, the roll coil of strip very easily skids on reel, cause reel middle part serious wear, sometimes also there will be the situation of unexpected fracture, affect the service life of reel; The 2nd, cannot use automatic deviation rectifying device (EPC), only rely on outlet side guide and guard and reel self to regulate, easy sideslip when strip coiling, causes even cassette tape phenomenon of coil of strip misalignment.
Utility model content
The purpose of this utility model is to provide a kind of oval reel, and it can extend service life of reel, again can be in the time of the operation of band steel automatic deviation correction.
The utility model solves the technical scheme that its technical problem adopts:
A kind of oval reel is provided, comprise hollow shaft, fanning strip, pyramid axle and copper plunger, 4 described fanning strips are evenly distributed on the periphery of hollow shaft, described copper plunger connects fanning strip and rib vertebra axle through the locating hole in hollow shaft, the top of described copper plunger is T-shaped flange, match with the T-shaped groove of fanning strip, the bottom of described copper plunger is sloping platform face, the vertical cross-section of described sloping platform face is T-shaped flange, match with the T-shaped groove of sloping platform face on rib vertebra axle, described copper plunger can radially slide under the effect of rib vertebra axle sloping platform face, the outline of described fanning strip is oval, 4 fanning strips form a complete oval revolving body.
By technique scheme, on the sloping platform face of described pyramid axle, be provided with batter post, in described batter post, be provided with dish spring, the top of described dish spring contacts with fanning strip.
By technique scheme, the top at described fanning strip two ends is provided with positioning sleeve, and described positioning sleeve is arranged in hollow shaft.
The utility model, has following beneficial effect: the utility model adopts oval fanning strip, and protrude at reel middle part, can increase the effective wear extent of reel, increase the service life, simultaneously, oval reel centring property is good, while batching, can reduce strip running deviation amount, contributes to steel edge portion neat.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing:
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the enlarged diagram of batter post.
Wherein: 1-hollow shaft, 3-positioning sleeve, 4-copper plunger, 5-hold-down bolt, 6-gland, 7-butterfly spring, 8-batter post, 9-fanning strip, 10-T type groove, 11-pyramid axle.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
In preferred embodiment of the present utility model, as shown in Figure 1, provide a kind of oval reel, comprise hollow shaft 1, fanning strip 9, pyramid axle 11 and copper plunger 4.4 fanning strips 9 are evenly arranged in the periphery of hollow shaft 1, the outline of fanning strip 9 is oval, 4 fanning strips 9 form a complete oval revolving body, the top at fanning strip 9 two ends is provided with positioning sleeve 3, its maximum outside diameter consistent size while being used for ensureing the swollen footpath of reel, positioning sleeve 3 is arranged in hollow shaft 1.Copper plunger 4 connects fanning strip 9 and rib vertebra axle 11 through the locating hole in hollow shaft 1, the top of copper plunger 4 is T-shaped flange, match with the T-shaped groove of fanning strip 9, the bottom of copper plunger is sloping platform face, and the vertical cross-section of this sloping platform face is T-shaped flange, matches with the T-shaped groove 10 of sloping platform face on rib vertebra axle, when the reel rotating cylinder drive lip axis of cone 11 moves axially, copper plunger 4 can radially slide under the 11 sloping platform face effects of rib vertebra axle, promotes fanning strip 9 and moves up and down, and realizes drum-expanding.
As shown in Figure 2, on the sloping platform face of pyramid axle 11, be provided with batter post 8, in batter post 8, be provided with dish spring 7, the top of dish spring 7 contacts with fanning strip 9 by gland 6, gland 6 is connected with batter post 8 by hold-down bolt 5, when reel shrinks, butterfly spring 7 stretches, and makes fanning strip 9 all the time in tensioning state radially, to prevent that under drum collapsing state, fanning strip 9 gets loose.
The utility model adopts oval fanning strip, and protrude at reel middle part, can increase the effective wear extent of reel, increases the service life, and meanwhile, oval reel centring property is good, while batching, can reduce strip running deviation amount, contributes to steel edge portion neat.
Should be understood that, for those of ordinary skills, can be improved according to the above description or convert, and all these improvement and conversion all should belong to the protection domain of the utility model claims.
