The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1, six cabochon collapsible drums of present embodiment comprise drum mechanism built, and drum mechanism built one end connects support wheel 1, and the other end of drum mechanism built is connected and installed the main shaft 7 of reductor, and an end of main shaft 7 connects rotary oil cylinder 8 and swivel joint 9; Cylinder lever connecting rod 15 on the piston rod of rotary oil cylinder 8, and pull bar 15 passes respectively in main shaft 7 and the drum mechanism built, and a side of drum mechanism built is connected with hollow shell 2;
See Fig. 2, Fig. 3, Fig. 4 and Fig. 5; The structure of drum mechanism built is: main shaft 7 is installed on the pull bar 15; Be positioned on the outer circumference surface of main shaft 7 at drum mechanism built place staggered 120 ° and be respectively arranged with three chutes; Wedge 14 is installed in the chute, a plurality of first screws 12 are installed on the wedge 14, fastening on wedge 14 axial directions through a plurality of first bolt, 13 main shafts 7; Wedge 14 outsides cooperate respectively fanning strip 11 are installed; The inboard of fanning strip 11 is provided with the inclined-plane with wedge 14 wedge-like portion Contact Transmission; The excircle of fanning strip 11 staggered place with it is equipped with three arc plates 21 through retaining mechanism 5, and arc plate 21 constitutes circular housing body 4 with fanning strip 11 on its circumferencial direction; Pull bar 15 1 ends are equipped with axially movable push pedal 10 in hollow shell 2;
See Fig. 6 and Fig. 7; Being positioned at wherein, an arc plate 21 inboards are equipped with second jaw plate 26 through holding screw 25; With arc plate 21 adjacent fanning strips 11 the second band pucellas mouth cavity 6 that forms the bite strap steel between first jaw plate, 22, the second jaw plates 26 and first jaw plate 22 is installed through locking member.
The structure of retaining mechanism 5 is: comprises that first double-screw bolt, 18, the first double-screw bolts 18 open counterbore from 21 of arc plates and penetrate in the main shaft 7, is positioned on first double-screw bolt 18 of counterbore and is with disk spring 19, and with blind nut 20 lockings.
The mounting structure of first jaw plate 22 is: have deep gouge on fanning strip 11 1 side planes, first jaw plate 22 is installed on fanning strip 11 1 side planes through second double-screw bolt 28, is with rectangle spring 27 on second double-screw bolt 28 in the deep gouge; The outer surface of first jaw plate 22 is provided with tooth-shape structure.
Be equipped with at interval on fanning strip 11 and the main shaft 7 axial installation directions and radially slide mechanism.The structure that radially slides mechanism is: be respectively arranged with the groove that cooperatively interacts on fanning strip 11 inner planes and main shaft 7 outer circumference surfaces, the guide pad 16 that radially slides is installed in the groove, guide pad 16 is fixed on the main shaft 7 through second screw 17.
The mounting structure of push pedal 10 is: pull bar 15 1 ends are equipped with push pedal 10, and push pedal 10 is through axial location on double nut 23 and the pull bar 15, and is fastening with the end face of wedge 14 through second bolt 24 on the circumferential end surfaces of push pedal 10.
In the actual use, accomplish through following steps:
(1) sees Fig. 2 and Fig. 3,, can under the drive of the first band pucellas mouth cavity 3, realize easily tentatively bringing in the drum mechanism built with steel one side simultaneously when band steel toe portion inserts the second band pucellas mouth cavity 6 on the drum mechanism built; Start rotary oil cylinder 8; The piston rod pulling pull bar 15 of rotary oil cylinder 8 moves to right, and the push pedal 10 that is fixed on 15 1 on pull bar moves right, and drives three wedges 14 and in the axial slide of main shaft 7, also moves right; And fanning strip 11 does not move axially; Because the axially movable to the right action of wedge 14 makes wedge 14 and fanning strip 11 hypotenuse mating reactions produce fanning strip 11 radially to extending out, and realizes tensioning; Simultaneously, because fanning strip 11, drives arc plate 21 radially to the effect that extends out radially to extending out, the guide pad 16 that then radially slides mechanism radially outwards slides in groove, and then the disk spring 19 of retaining mechanism 5 is in compressive state; And because fanning strip 11 is radially to the effect that extends out; Rectangle spring 27 is compressed; First jaw plate 22 moves axially along second double-screw bolt 28 under the effect of rectangle spring 27 elastic force, and the bore of the second band pucellas mouth cavity 6 is diminished, and clamps the band steel; Start coiling machine, the band steel just batches around fanning strip 11 outers.
(2) see Fig. 4 and Fig. 5, batch end after, the piston rod of rotary oil cylinder 8 pulling pull bar 15 moves to left; The push pedal 10 that is fixed on 15 1 on pull bar is moved to the left; Drive three wedges 14 and in the axial slide of main shaft 7, also be moved to the left, and fanning strip 11 does not move axially, because the axially movable left action of wedge 14; Make wedge 14 and fanning strip 11 hypotenuse mating reactions produce fanning strip 11 and radially inwardly contract, realize undergauge; Simultaneously; Because the effect that fanning strip 11 radially inwardly contracts; Drive arc plate 21 and radially inwardly contract, the guide pad 16 that then radially slides mechanism radially inwardly slides in groove, and then the disk spring 19 of retaining mechanism 5 becomes releasing orientation by original compressive state; And because the effect that fanning strip 11 radially inwardly contracts, rectangle spring 27 is in relaxation state, and first jaw plate 22 is along with fanning strip 11 bounces back together, and the bore of the second band pucellas mouth cavity 6 becomes big, and drum diameter dwindles, and the roll coil of strip can take off easily.
The present invention will reel through the present invention the volume of the band coil of strip coiled after rolling in the useful application process to the band steel.Behind the coiling, directly the roll coil of strip is reeled with certain diameter through rising of reel, when the reel undergauge, easily the roll coil of strip is unloaded from reel, it is easy and simple to handle, and is easy to use.
Material according to the band steel is different, just can obtain suitable clamping force through size and the quantity that changes disk spring 19.
The present invention is particularly useful for the power reel below the thickness 1.2mm, when the thickness of band steel during less than 1.2mm, because the present invention is through three arc plates 21 and three fanning strips 11 are staggeredly placed on its circumferencial direction respectively; And formation circular housing body 4; The quantity of the cambered surface that increases, its roundness of circular arc that the footpath of rising forms is good, has avoided prior art to be prone to produce the phenomenon of losing circle; When strip coiling, guaranteed that the band coil of strip is around quality.Simultaneously, the present invention also is applicable to the band steel steel plate of 3mm.
More than describing is to explanation of the present invention, is not that institute of the present invention restricted portion within protection scope of the present invention, can be done any type of modification referring to claim to the qualification of invention.
