Can also be other springs having compared with high tension in example.
The working condition of the roll device of the sheet metal strip of the present embodiment has three：
Working condition 1：When first piston 124 is in limit on the left position, cross flange 26 is in axial voussoir 22
Limit on the left position, while radial direction voussoir 23 is in reel radial position most inner side state, i.e. undergauge state, such as the main view in Fig. 1
Shown in figure lower state；At the same time, because radial direction voussoir 23 is in reel radial position most inner side state, four fanning strips 24
In the presence of the first spring 242, radial direction minimum dimension location status is retracted into, reel radial dimension is retracted into Φ a, such as Fig. 2
Shown in view；At the same time, because radial direction voussoir 23 and each fanning strip 24 are relative to the displacement difference of reel axis center, form away from
From the opening degree for X, as shown in Figure 4.
Working condition 2：When second piston 125 is in limit on the left state, and first piston 124 is to the snap of second piston 125
During position, cross flange 26 moves right certain distance with axial voussoir 22, while radial direction voussoir 23 is to reel radial position
Outside moves a certain distance, i.e. reel spreading certain size state, as shown in the front view upper states in Fig. 1；At the same time,
Because radial direction voussoir 23 is to moving a certain distance on the outside of position, effect of the fanning strip 24 in the first spring 242 and radial direction voussoir 23
Under, reach Φ b to away from reel shaft core position spreading certain size, reel radial dimension, as shown in Figure 2；At the same time, due to
With each fanning strip 24 relative to the displacement difference away from reel axis center, distance becomes for X opening degree stings tightly radial direction voussoir 23
State.
Working condition 3：When second piston 125 is in limit on the right-right-hand limit state, and first piston 124 is to the snap of second piston 125
During position, cross flange 26 moves right certain distance again with axial voussoir 22, while radial direction voussoir 23 is again to reel
Move a certain distance on the outside of radial position, i.e. reel spreading certain size state again, such as the front view upper states institute in Fig. 1
Show；At the same time, because radial direction voussoir 23 moves a certain distance to position outside again, fanning strip 24 is in the He of the first spring 242
In the presence of wedge, again to away from reel shaft core position spreading certain size, reel radial dimension reaches Φ c, such as Fig. 2 institutes
Show；At the same time, reel, which is kept, stings tight state, as shown in Figure 5.
In above-mentioned three state handoff procedure 4 axial wedges only along spool shaft 21 4 left axial movements of guide groove,
And four radial direction wedges 23 and four fanning strips 24 also only radially move.Drum diameter change Φ a<Φb<Φc.
The roll device of this sheet metal strip can be used for upper volume, uncoiling, winds, unreels, and unload a variety of occasions such as volume.
1st, upper volume；
Reel is first switched to above-mentioned state 1, drum diameter is Φ a, now band volume internal diameter Φ bands, then Φ a<Φ bands<Φ
C, after band volume widthwise central is attached to drum center position, above-mentioned state 3 is switched to, then band volume internal diameter is realized by reel tensioner
Upper volume.
2nd, uncoiling；
After upper end of volume (EOV), band volume can be deployed, i.e. uncoiling.Band can be applied due to internal diameter tensioner, during uncoiling
Some tension F.
3rd, wind；
Reel is first switched to above-mentioned state 1, drum diameter is Φ a, and the opening degree for stinging material mouth is X, by thickness<X band
Material is switched to above-mentioned state 2 through after stinging in material mouth, by reel, now rolls up internal diameter and increases to Φ b, stings material mouth and sting tightly, can be received
Volume, can also be to band application some tension F during winding because band has been snapped tightly.
4th, unreel；
Winding terminate rear reel can continue reversely rotate band volume deploy, that is, unreel, due to winding when band be snapped tightly,
Unreel Shi Yike and some tension F is applied to band.
5th, volume is unloaded；
Winding terminates rear reel and switches to above-mentioned state 1, and now, drum diameter is Φ a, band volume internal diameter Φ band=Φ b,
It can will be unloaded with volume from reel, that is, unload volume.
6th, reversible rolling.
When uncoiling and winding are applied in combination, or unreel and winding is applied in combination, can when milling train is arranged between two reels
For reversible rolling.The advantages of this reel is can be by Φ a<Band volume internal diameter<Φ c band volume internal diameter, is unified for Φ b after rolling
Or Φ c, that is, realize two kinds of volume internal diameter specifications.
The roll device of the sheet metal strip of the present embodiment, it is engaged, stings tight relatively reliable due to being promoted by wedge shape, it is possible to provide
Bigger coiled strip tension force, while the opening and closing of reel is moved axially by output shaft and realized, meets requirement significantly, is dropped
The low labor intensity of user, improves automaticity, the scope of application is wider.
Use above specific case, such as specific title, symbol, parameter, it is intended to be illustrated to the present invention, simply
It is used to help understand the present invention, is not intended to limit the invention.For those skilled in the art, according to this
The thought of invention, some simple deductions, deformation can also be made or replaced.
