Maximum, the part at the cylindrical top of wedge 4 is from the gap between three pieces of fanning strips 2 or between fanning strip 2 and jaw fan-shaped 5
It is protruding, enhancing tension force can be fully contacted under such a state with band, does the use of uncoiling reel.
When specifically used：When roll bending starts, reel is in smallest circle working condition, drive of the pull bar 11 in expanding cylinder 13
Under, the adpting flange 12 that is attached thereto it, while drive fanning strip breathing wedge 6 and axial wedge 3 to axially move.It is fan-shaped
The wedge of plate breathing wedge 6 promotes fanning strip 2 and jaw fan-shaped 5 makees radial motion, while the wedge promotion of axial wedge 3 is outer
Circle wedge 4 make radial motion, so as to fanning strip 2,5 synchronous breathing of jaw fan-shaped.When the upper cavity of hydraulic cylinder 7 is in pressurising shape
During state, hydraulic tongs pig's tongue 9 is moved down, and jaw is opened, by feeding mechanism pan feeding, the lower chamber pressurising of hydraulic cylinder 7 after pan feeding, and its piston
Bar promotes hydraulic tongs pig's tongue to move up, and jaw clamps supplied materials.
When batching, expanding cylinder 13 is extended to one-level stroke, and fanning strip breathing is driven by connecting rod 11 and adpting flange 12
Wedge 6 and axial wedge 3 axially move, the 4 affected radial motion of fanning strip 2, jaw fan-shaped 5 and cylindrical wedge, reel
It will swell to positive round working condition, will be batched with volume swelling.
When unloading volume, the upper cavity of hydraulic cylinder 7 is in pressurising state, its piston rod retraction, drives hydraulic tongs pig's tongue 9 to move down, clamps
Mouth is opened, and unclamps strip steel head, and connecting rod 11 is gone back in the presence of contract cylinder 13, drives fanning strip swollen by adpting flange 12
Contracting wedge 6 is gone back, and hauls fanning strip 2 and the return of jaw fan-shaped 5, while is hauled cylindrical wedge 4 and bounced back together, and reel will
Smallest circle state is bounced back to, makes there are enough gaps to unload volume between coil of strip and reel.
During uncoiling, expanding cylinder 13 is extended to second level stroke, and fanning strip breathing is driven by connecting rod 11 and adpting flange 12
Wedge 6 and axial wedge 3 continue to axially move on the basis of one-level stroke, fanning strip 2, jaw fan-shaped 5 and cylindrical
Wedge 4 continues to make radial motion, and reel will swell to greatest circle working condition, and cylindrical wedge 4 is higher by fanning strip 2 and jaw is fan-shaped
Plate 5, swelling band volume, carries out uncoiling.
To sum up, fan is passed through as other fanning strips by means of above-mentioned technical proposal of the present utility model, jaw fan-shaped
Shape plate breathing wedge is connected in spool shaft, and fanning strip breathing wedge is with axial wedge by being fixed to pull bar together with adpting flange
On, realize the breathing synchronous with fanning strip of cylindrical wedge, avoid when unloading volume inner ring of steel coil by reel scratch or be carried over and
Influence scroll；Expanding cylinder can realize fanning strip breathing synchronous with cylindrical wedge, and can realize the function of batching with uncoiling.
Preferred embodiment of the present utility model is these are only, it is all in this practicality not to limit the utility model
Within new spirit and principle, any modification, equivalent substitution and improvements made etc., guarantor of the present utility model should be included in
Within the scope of shield.
