Background technology

In existing rolling/active unwinding and rewinding machine,, all do not have auto-lock function if there is employing cylinder/hydraulic actuating cylinder to realize the swelling function of swelling watt.That is, when taking place to reveal when cylinder/hydraulic actuating cylinder or with its bonded assembly gas circuit/hydraulic tubing, the air pressure or the hydraulic pressure that act in the cylinder body on the piston descend, and swelling watt will lose enough tension forces.When swelling watt loses enough tension forces, for the machine of vertical unreeling/rolling, still can the material volume still can be positioned in the swelling watt (or being referred to as reel) owing to the deadweight of material volume.But for level unreel/machine of rolling for; Be easy to cause the material volume to fly out or expect that volume scatters owing to rolling/tension force when unreeling or the reasons such as whirling vibration of machine; And in case the volume that takes place to loose; Then generally can't raw material be reverted to original state again, so this just causes serious safety misadventure or causes serious wastage of material.

If but the cylinder/hydraulic actuating cylinder that will have auto-lock function simply is applied to and unreels/the winder field, can there be following problem again:

1, the self-locking of cylinder/hydraulic actuating cylinder only is to keep the position of throw rod motionless; And can't guarantee to provide a lasting constantly application force to make swelling watt have enough tension forces to come the inboard of swelling material volume; Watt can not withdraw and only satisfy swelling; Be merely simple passive bearing force but not the actv. tension force between swelling watt and the material volume inboard; Be actually like this and rise not tightly, for example patent application 201010138295.0 disclosed spool material retractable feeders just do not adopt self-locking cylinder to hold out against I-beam wheel; If the internal diameter of 2 material volumes is not completely unified, internal diameter is less than normal slightly, will cause the piston of self-locking cylinder/hydraulic actuating cylinder full action to put in place; Self-locking device can't start; Internal diameter is bigger than normal slightly, will cause the piston full action of self-locking cylinder/hydraulic actuating cylinder to put in place after, self-locking device starts; It is inboard that swelling watt also can't swelling material volume, also still should have more than is needed self-locking cylinder/hydraulic actuating cylinder.

So self-locking cylinder/hydraulic actuating cylinder is applied to unreel/the winder field, avoid leaking gas or leakage to the influence of machine run safety and reliability, be that those skilled in the art thirsts for solving and the problem of failing to succeed always.

See also Fig. 1, Fig. 5, the cylinder bar of cylinder 33 is hinged with the side arm end of vee shape connecting panel 35 through connector 36.Correspondingly; The side arm of the vee shape connecting panel 35 of arm structure both sides is arranged in a crossed manner; Promptly two connecting panels 35 are vertical each other; In the space of the vee shape inside bottom of each connecting panel 35 between the vee shape two side arms of another connecting panel 35, utilize space between each vee shape two side arms hold the bottom of another connecting panel and with it pivotally attached, be positioned at the connection wye 34 of tie rod end, this connection wye 34 is threaded in the inner end of pull bar 17.When so the size of connecting panel should guarantee that the cylinder bar is released; The bottom of two vee shapes can not interfere, and simultaneously the width between the vee shape two side arms should and be used for the length of bearing pin of the Y joint 34 of hinged vee shape connecting panel bottom and tie rod end greater than the thickness of connecting panel.

Connection wye 34 is threaded in the inner end of pull bar 17, and connection wye 34 adopts the jam nut locking that is connected on the pull bar 17, between jam nut and Y joint, installs stop washer (GB/T 858-1988) additional, can limit the rotation of connection wye with respect to pull bar.In other words, owing to be that the plane is hinged between connection wye and the connecting panel, and connecting panel can not rotate, thus connection wye also can not rotate, so also just limited the rotation of pull bar.

Because exoskeletal accurate after-combustion steel coil strip is different from the wide cut steel coil strip, wide cut steel coil strip width can reach about 1m even be more, and the width of wall scroll steel band and the thickness of steel coil strip are bigger, are not prone to the problem that steel band scatters to the side.And use steel coil strip for flux-cored wire, and width of steel band is 10～20mm, and in arbitrary section, one deck steel band generally has the steel band more than 20, and the probability that such steel coil strip generation is scattered to the side is more much bigger than wide cut steel coil strip.So need baffle plate be set in the steel coil strip both sides, in case the steel band in the steel coil strip scatters to the side.

Drive socket 28 is connected with chain drive, and chain drive is driven by motor reducer 61, and motor reducer 61 is installed on the casing.This unreeling machine not only can carry out initiatively unreeling operation can also carry out the rolling operation.

See also Fig. 1; In order to prevent that the inside side of steel band in the steel coil strip from scattering, on drive socket 28, be provided with Internal baffle assembly 2, drive socket 28 is packed in the outside of turnbarrel 13; The Internal baffle assembly is packed in the outside of drive socket 28; Drive socket 28 outer ends are provided with and are used to locate the inboard shaft shoulder of Internal baffle assembly, and the outside of Internal baffle assembly is held out against by Internal baffle steady ring 29, and Internal baffle steady ring 29 is fastened on the drive socket 28 through screw.

Because exoskeletal accurate after-combustion steel coil strip is on lifting active unwinding and rewinding machine the time; Can not be directly the side of steel coil strip be against on the rectangular steel tube of Internal baffle assembly because along with the radial direction of swelling watt outwards, axial direction moves to machine intimate, the path of motion of steel coil strip and the swelling that it is propped up are watt the same; One-component can be arranged in the axial direction; If directly the side with steel coil strip is against on the rectangular steel tube of Internal baffle assembly, can the generation relative motion between steel coil strip and the swelling watt, and also the friction force of relative motion is bigger; One deck or which floor steel band in the inner end edge of swelling watt might be destroyed cause whole steel coil strip to be subsided.So can not directly make the axial direction positioning device of lifting steel coil strip of the Internal baffle assembly.In lifting during steel coil strip, need steel coil strip be placed in the swelling watt, just need have a location device this moment in swelling watt, to control steel coil strip in axial position.

See also Fig. 1, in the present embodiment, swelling watt inner reinforced plate 8 is provided with inboard registration device 37, and inboard registration device is installed in the end of swelling watt gusset near casing.Inboard registration device comprises two connection boards that are installed in swelling watt inner reinforced plate both sides; Connection board is L shaped; Horizontal bottom conduct and swelling watt gusset bonded assembly connecting portion, vertically portion is as the location division, and the connecting portion of connection board is provided with horizontal slotted hole; Be provided with the fixing screw of connection board in the horizontal slotted hole, fixing screw is fixed together a connection board and a swelling watt gusset.Horizontal relative position through parallel motion connection board control itself and fixing screw; Can adjust the relative position of inboard registration device and swelling watt; Guarantee steel coil strip after fully by swelling, its inside edge can contact with the square tube of Internal baffle assembly, the location of realization steel band.

See also Fig. 3, Fig. 4 a and Fig. 4 b, locate in like manner with the inboard, initiatively the arranged outside of unwinding and rewinding machine has outside registration device, and outside registration device is a demountable structure.Outside registration device comprises steel band outer baffle and outer baffle registration device; The steel band outer baffle comprises outer ring 381, inner ring 383 and the spoke that is connected outer ring and inner ring 382, constitutes by metal tube with top.The outer baffle registration device comprises two pilot bars 392 and two abutment sleeves 385; Two abutment sleeve 385 disalignments, the average level setting, the length of one of them abutment sleeve is greater than another abutment sleeve, and two abutment sleeves 385 respectively are connected with the inner ring 383 of outer baffle through radius stay 384; Two pilot bars 392 respectively are fixed on the outer circumference surface of turnbarrel 27 through riser 391, and two pilot bars 392 are installed on respectively in two abutment sleeves 385, and the end of pilot bar 392 is provided with screw thread, and a setscrew nut has been threaded on the screw thread.Through two point locations and a line location, can limit the axial location of outer baffle device, and can limit the outer baffle swing like this.

In the present embodiment, the connection structure of casing and base, similar with disclosed connection structure among the patent documentation CN201525655U, the present invention repeats no more at this.

Like Fig. 6 a～Fig. 6 b and shown in Figure 1, the principle of work of present embodiment is:

One) shown in Fig. 6 a the first half; Before the lifting steel coil strip; The displacement cylinder group of respective side is shunk, and displacement cylinder drives pull bar through connecting panel and stretches out, and the circlip for shaft on the pull bar promotes the first inner ring sleeve and the second inner ring sleeve; The second inner ring sleeve promotes the inner ring of two-direction thrust bearing, and promotes roller bearing end cap through two-direction thrust bearing.Because roller bearing end cap and plain bearing chamber are connected; The plain bearing chamber is also along with roller bearing end cap outwards moves together; The outdoor gusset of plain bearing that is packed on the plain bearing chamber also outwards moves thereupon together, and the angle between swelling connecting rod and the axis reduces, and the angle between support link and the axis reduces simultaneously; Swelling watt edge is that the circular arc of radius outwards moves with the distance between two hinge-points of support link and swelling connecting rod, and the external diameter of swelling simultaneously watt also dwindles thereupon.When the outer gusset of the inner reinforced plate of swelling watt and turnbarrel contacted, the external diameter of swelling watt was retracted to minimum value, and cylinder still possibly not shunk and put in place this moment.

Because the axial location of inboard registration device on swelling watt gusset can be regulated, so before the lifting steel coil strip, need adjustment to confirm the position of inboard registration device.If directly steel coil strip is placed in the swelling watt, the standard of neither one location, the workman confirms the position of steel coil strip entirely by rule of thumb; So very possible bigger than normal or less than normal; If steel coil strip is near excessively apart from the outer end, will cause swelling watt after swelling, the inboard of steel coil strip still can't touch on the square tube of Internal baffle; Steel coil strip does not have the location, side, and the steel band that keeps to the side most still might subside.If inboard registration device is far away excessively apart from the outer end; Though can utilize the square tube of Internal baffle accurately locatees the side of steel coil strip; But can increase the distance of the friction of steel coil strip and swelling watt support; For the steel coil strip that does not have paper web, this is with steel strip surface the most inboard in the severe wear steel coil strip, and the wire feed when administration core welding wire is produced follow-up drawing work or use brings difficulty; For the steel coil strip that has paper web as the inner tube of a tyre,, also can strengthen wearing and tearing to recycled paper web though there is not the problem of the steel strip surface of wearing and tearing.And except wear problem, when steel coil strip and swelling watt relatively moved, friction force needed the application force of cylinder to overcome, and undoubtedly can increase the load of cylinder, might cause the increase of cylinder size.After having increased inboard registration device, can be after once adjusting to the right place, it is carried out fastening, each just all had a good reproducibility when going up volume, and the position reference of accurate positioning need not to adjust once more, can avoid above-mentioned problem.

Two) steel coil strip is placed in that swelling watt is gone up and axial location after, cylinder is stretched out, the connector on the cylinder bar drives connecting panel, and then drives the pull bar withdrawal, the nut of tie rod end compresses disc spring sleeve, disc spring sleeve compression belleville spring group.Because the belleville spring group is not in compressive state when pull bar stretches out fully little when amount of compression will be more than the lifting steel coil strip in other words; So this moment, cylinder only was through pull bar compression belleville spring group; And do not cause other variations; For example can suppose that the distance between this moment dish spring support ring and first shaft shoulder is 5mm, state is shown in the lower part of Fig. 6 a at this moment.Certainly; If select the cylinder of less stroke for use in order to reduce the space in the casing, swelling watt inner reinforced plate still is suspended from the outer gusset of turnbarrel in the time of can causing the cylinder contraction to put in place, and both can not dock; If will expect volume in this case is placed in the swelling watt; Can move plain bearing is outdoor through the swelling connecting rod, through two-direction thrust bearing, the first inner ring sleeve, dish spring carrier ring with force transmission on dish spring group, dish spring group is compressed.It would, of course, also be possible to is above the two combination, i.e. the swelling watt inner reinforced plate segment distance that descends, and after one section of dish spring group compression, swelling watt inner reinforced plate falls to placing on the outer gusset of turnbarrel, when pull bar moves inward then, again dish spring group is continued one section of compression.

When compressive force suffered on the belleville spring group reaches need steel coil strip be risen required application force the time; The plain bearing chamber is (this power is delivered on the plain bearing chamber through dish spring support ring and two-direction thrust bearing) under the elastic force effect of belleville spring; In turnbarrel, move; And then through swelling connecting rod and support link swelling watt is propped up, this moment, the center of gravity of steel coil strip constantly rose.

Since swelling watt swelling when putting in place swelling connecting rod and support link be greater than the angle of these two connecting rods when just having begun the lifting steel coil strip with respect to the angle of axis; So stressed (belleville spring stressed) during swelling on the connecting rod is less than the power when just beginning the lifting steel coil strip; The length of belleville spring is greater than its length when just beginning the lifting steel coil strip; In lifting the process of steel coil strip; Belleville spring comes down to discharge its amount of compression constantly, and the distance between the dish spring support ring and first shaft shoulder is 1.5mm at this moment, and this moment, state was shown in the first half of Fig. 6 b.This moment, dish spring group still had certain compression surplus.So watt with steel coil strip after the complete swelling, cylinder still continues to release a segment distance in swelling, pull bar continues to shrink inwards, disc spring sleeve compression belleville spring group.Until reaching the cylinder stroke; Cylinder in-to-in with lock lock is locked cylinder, prevents that cylinder from losing thrust because of gas leakage, causes expecting to roll up the accident that flies out; Distance between the dish spring support ring and first shaft shoulder is 3.5mm at this moment, and this moment, state was shown in the latter half of Fig. 6 b.Be belleville spring by the length of another compression in the swelling watt length that the cylinder bar continues to stretch out after the complete swelling with steel coil strip, then this length is 2mm.When parts such as cylinder, connecting panel, connector, pull bar are installed accurately more, this length is needed just more little, and the second-compressed amount of spring is also just more little, and the pressure during final initiatively unwinding and rewinding machine operation on the dish spring group is also just more little.For above-mentioned reasons, initiatively during the operation of unwinding and rewinding machine, in other words, the axial force after the steel coil strip swelling is less, and after machine run got up, the two-direction thrust bearing in the outside and inboard thrust baring stressed also less helped improving the thrust baring life-span.

The generation of second-compressed amount is not only in order to remedy the error when installing, and has the effect that tension force is provided concurrently.Because in fact in the swelling watt process that constantly struts, the swelling watt bearing capacity for the material volume also only is to equal to expect the gravity rolled up, then the elastic force on belleville spring this moment also be with this bearing capacity to cooresponding.If there is not second-compressed; That swelling watt will be the same (owing to the geometric relationship between swelling connecting rod, swelling watt, support link and the pull bar with not using dish spring group to the tension force of material volume; Can not produce bigger tension force, otherwise will cause structural damage) use the advantage of disk spring group to give prominence to so.And the generation of this second-compressed amount; Then over against the generation of having answered additional tension force; And this tension force can not disappear because of the gas leakage/leakage of cylinder, and this additional tension force exactly, and guaranteeing can have enough friction force between swelling watt and the material volume the most inboard (or material roll up paper web); Control the raising speed/reduction of speed of honest material convolution commentaries on classics etc., improved the safety and the reliability of system.For example; The weight of material volume is 1000 kilograms, and when swelling watt will expect to roll up complete swelling, the application force on the dish spring group was 800 kgfs; Because the second-compressed of dish spring group; Application force on the dish spring group has increased by 320 kgfs again, has increased the tension force of 400 kgfs so between swelling watt and the material volume inboard again, and this has just increased swelling and watt has rolled up the friction force between the inboard with material.

Owing to adopt the active unwinding and rewinding machine or the winder of swelling watt swelling material volume inner core to be different from I-beam wheel unwinding and rewinding machine.The material of I-beam wheel unwinding and rewinding machine volume is placed on the I-beam wheel (or being referred to as drum), the rotative speed of I-beam wheel is to embed in the hole in the I-beam wheel through the finger on the unwinding and rewinding machine, stirs I-beam wheel and rotates to regulate its rotating speed.And adopt the rotating speed of the confidential adjusting material volume of material retractable of swelling watt to regulate its rotating speed through the friction force that swelling watt and material are rolled up between the inner core; And friction force is by tension force and friction coefficient decision; And friction coefficient be immobilize moving, so can only improve friction force through increasing tension force.

In case the piston motion of self-locking cylinder puts in place, the application force that the cylinder of the active unwinding and rewinding machine of the existing form of employing externally applies is and overcomes the required pairing dish spring force of bearing capacity of material volume weight, and for example the piston area of cylinder is 314cm ², air pressure is 4kgf/cm ², then the cylinder power that can externally apply in theory is 1256kgf, but in fact can only externally apply 800kgf after the self-locking, remaining 1256-800=456kgf can only act on the cylinder bottom of cylinder.For example the friction coefficient between tensioner watt and the material volume is 0.3, and then the friction force of every swelling this moment watt can only be 300kgf.If tensioner puts in place before self-locking, cylinder no longer moves, and cylinder on the contrary can outwards be exported the 1256kgf application force, but has not had self-locking, in case cylinder leakage tester will be easy to expect to roll up the accident that flies out.

But after the present invention had increased belleville spring, belleville spring can also carry out second-compressed, and swelling watt can increase extra tension force again, increase for example mentioned above the tension force of 400kgf, and this swelling watt total can increase the friction force of 120kgf again.And the technical scheme in the employing present embodiment; Raising tension force that can be bigger; And then the unwinding and rewinding machine that improves employing swelling watt form is rolled up the control ability of velocity variations to material; Acceleration/accel that needs are bigger in the time of can adapting to speed governing and/or material are rolled up the bigger occasion of rotor inertia, have expanded the range of use of such machine.

Three) after the swelling operation is accomplished; Outer baffle is contained in the swelling watt; Utilize two abutment sleeves and two pilot bars to realize the location to outer baffle, wherein two abutment sleeves have been accomplished point location jointly, and long abutment sleeve has also been accomplished and prevented the location of swinging; Use nut locking then, can play protective effect the outer side edges of steel coil strip.

After accomplishing the location, the outside of steel coil strip, can begin the passive band of putting.

Dish spring group in the present embodiment also can be replaced by the elasticity of compression parts of other type; Other compressibi1ity springs of being mentioned in can the 11st piece of spring chapter 1 spring of Chemical Industry Press's version " mechanical design handbook " in 2002 the 3rd volume referring to Cheng Daxian chief editor; Resilient sleeve for example, cylindroid helical-coil compression spring etc.Nut 16 can be replaced by the limiting stopper of pin joint or the locating dowel pin through the pull bar axis.

Embodiment 2:

Most of identical with embodiment 1, just changed the connection mode of cylinder and pull bar.In embodiment 1, stretch the contraction that realizes pull bar, in the present embodiment, shrink the contraction that realizes pull bar through cylinder through cylinder.

See also Fig. 9; Pull bar with the left side is an example; The cylinder 33 of drive stay 17 also is two one group; But different is cylinder bar towards the left side (near the direction of connected pull bar outer end) stretch out, the end of each cylinder cylinder bar also is to be connected with a side arm end of V-arrangement connecting panel 35 through a connector 36.Different is: the connecting panel length in the present embodiment is shorter than the connecting panel among the embodiment 1; And opening direction is different from embodiment 1; Therefore the top of V-arrangement connecting panel 35 is directly arranged dolly respectively with at the bottom of two V-arrangement connecting panels of two groups of pull bar cylinder bonded assemblys than the outer end of its bottom near connected pull bar 17 in the present embodiment.Be responsible for 35 operations in the machine center line is regional with a left side of connecting panel of push-and-pull left side pull bar; Be responsible for the only operation in the machine center line is regional with the right side of connecting panel of push-and-pull right side pull bar; The inner bottom part of vee shape connecting panel is relative with the breeches joint on the pull bar and hinged; Be that breeches joint 34 on the pull bar is in the space between the two side arms of vee shape connecting panel, the distance between vee shape connecting panel 35 two side arms should be greater than the width of connection wye.

Present embodiment also provides the connection structure of another kind of cylinder cylinder bar and pull bar:

Referring to Figure 10 a, still the pull bar with the left side is an example, and the cylinder 33 cylinder bars that drive stay moves also stretch out towards the left side, but cylinder 33 cylinder bars are different with the connection mode of pull bar 17 the inners.In Figure 11, the cylinder bar that is used for the cylinder group of drive stay 17 is provided with the connecting panel vertical with them 46, and pull bar 17 is connected with U-shaped latch fitting 48 through coupling bush 47 with the middle part of connecting panel 46.Coupling bush 47 is arranged on the inboard of connecting panel 46, and the middle inside of coupling bush 47 is provided with a gap; Be provided with parallel two adaptive position-limited troughs with above-mentioned gap in the inner end cylindrical both sides of pull bar, the lateral surface of position-limited trough is the inclined-plane; U-shaped latch fitting 48 is inserted in the position-limited trough of pull bar 17; Inside and outside both sides are by the madial wall cramping of gap bottom surface and position-limited trough; The side arm cramping of U-shaped latch fitting 48 is between at the bottom of gap wall and the position-limited trough; The side arm of U-shaped latch fitting 48 is provided with the inclined-plane adaptive with the inclined-plane of position-limited trough, and the angle on this inclined-plane should be in the friction self-locking scope, can guarantee that the U-shaped latch fitting can not deviate from.The structure that U-shaped latch fitting 48 is inserted in the inboard gap of coupling bush can also prevent that pull bar from rotating.

The 3rd cylinder cylinder bar that present embodiment provides and the connection structure of pull bar; See also Figure 10 b; Still the pull bar 17 with the left side is an example, and the cylinder 33 cylinder bars that drive stay moves stretch out towards the left side, and the cylinder bar that is used for the cylinder group of drive stay 17 is provided with the connecting panel vertical with them 46; The outer middle side part of connecting panel 46 is provided with contiguous block 49, and contiguous block 49 is provided with T type groove; The inner end of pull bar is provided with the salient of radius greater than its adjacent part, and salient is contained in the T type groove.The direction of T type groove is 45 ° with the direction of the paired cylinder cylinder bar line of centres.

Embodiment 3:

First kind of structure: see also Fig. 1 and Figure 11 a, the afterbody of each cylinder all is hinged on the riser of casing, and the cylinder bar is connected with the inner of pull bar 17 through a lever 35.The inner of pull bar 17 is connected with a Y joint 34; Cylinder cylinder club head is equipped with the 2nd Y joint 36; The two ends of lever 35 are hinged with a Y joint 34 and the 2nd Y joint 36 respectively; Be elongated slot and non-circular hole with a Y joint hinged portion wherein, the middle part of lever 35 is connected with the casing riser and the 17 homonymy settings of driven pull bar of bearing 63 with to be fixed in casing riser upper bracket 63 hinged.

Second kind of structure: see also Figure 11 b; Form one group two cylinder 33 and second kind of structure of pull bar bonded assembly: be with the difference of above-mentioned first kind of structure; The afterbody of cylinder 33 is directly installed on the riser of casing; Lever 35 is used for should be elongated slot with a Y joint 34 and junction, the 2nd Y joint 36 pivotally attached end and non-circular hole will cause lever to rotate otherwise the connection between the three is the structure of " bearing pin+circular hole ".

Below 2 kinds of leverages different with above two kinds of leverages be to have changed the connection mode of cylinder and pull bar.In embodiment 1, realize the contraction of pull bar through stretching of cylinder cylinder bar, in the present embodiment, contraction through cylinder cylinder bar realizes the contraction of pull bar.

The 3rd kind of structure: see also Figure 12 a; Be with the difference of first kind of structure among the embodiment 1: the middle part of lever 35 and the 2nd Y joint 36 are hinged; One end of lever 35 and a Y joint 34 are hinged; Be elongated slot and non-circular hole with a Y joint hinged portion wherein, the other end of lever 35 is hinged with the bearing 63 that is fixed on the casing riser, and bearing 63 and cylinder were located at the both sides of pull bar 17 in 33 minutes.When cylinder was stretched out, pull bar is side shifting outside casing, and a swelling watt radius is reduced; When cylinder was shunk, pull bar moved to box house, made swelling watt spreading to setting diameter.

The 4th kind of structure: see also Figure 12 b; Be with the difference of above-mentioned first kind of structure; The afterbody of cylinder 33 is directly installed on the riser of casing; Cylinder bar 35 is used for should be elongated slot with a Y joint 34 junctions, pivotally attached end with junction, the 2nd Y joint 36 pivotallys attached middle parts and non-circular hole will cause lever to rotate otherwise the connection between the three is the structure of " bearing pin+circular hole ".

Embodiment 4:

Be the registration device of outer baffle with the difference of embodiment 1.See also Figure 13 a and Figure 13 b; In the present embodiment; The registration device of outer baffle comprises and is sleeved on the outer locking of swelling watt watts 53, is connected with the holding screw and the radius stay 54 that are pressed in the swelling watt in the locking watts 53, and radius stay passes 55 slips of outer baffle inner ring and is installed in the spoke 56; Radially be provided with slotted hole 561 on the spoke, be provided with the lock screw affixed in the slotted hole with radius stay.Locking watt compresses swelling through the holding screw on it and watt realizes locking, and radius stay compresses spoke through the lock screw on it and realizes the location.

Above-mentioned outer baffle registration device can be avoided the big problem of embodiment 1 outer baffle registration device difficulty of processing.Because in embodiment 1, outer baffle and turnbarrel are except the nested relationship of abutment sleeve and pilot bar; Be two incoherent parts fully; And the outer baffle pilot bar that is with abutment sleeve outward still is welded on the turnbarrel through riser, and through this hot working of welding, total just more likely produces new error because expand with heat and contract with cold; Reduce the quality of fit of abutment sleeve and outer baffle pilot bar; Increasing tolerance clearance needs to guarantee installation, thus, has improved the fugitiveness of outer baffle location; The raising working accuracy increases tooling cost.The two scheme all has certain drawback.

Outer baffle registration device among the embodiment 1; Owing to be provided with the outer baffle pilot bar in the end of riser; Pilot bar is in a single day stressed, for riser, is a cantilever beam structure of only having fixed at afterbody; And outer baffle pilot bar itself also is a cantilever beam structure of only having fixed at afterbody, and this structure is very unfavorable for carrying.In order to reduce the negative effect of riser cantilever beam structure; Can reduce the height of riser; If but reduced height, just need to increase the length of radius stay in the outer baffle registration device, and radius stay itself also would be a cantilever beam structure; If increase the length of radius stay, certainly will reduce its rigidity and load-carrying capacity again.And outer baffle is after being put into the material volume on the active unwinding and rewinding machine; Be manually installed on the active unwinding and rewinding machine; In order to reduce workman's work load; Need again as much as possible with outer baffle do lighter, so its material is also selected the material that density is less, intensity is relatively poor or wall thickness is thin for use, so that its rigidity is not easy to do again is too much.The two has just constituted contradiction.

Present embodiment; Change the registration device of outer baffle into the locking that directly is sleeved in the swelling watt watt; Locking watt shape and size and swelling watt coupling; No matter how a swelling watt formed circular outer diameter size changes, and the shape of swelling watt itself is fixed, so locking watt can watt realize stable cooperating with swelling.And the variation of swelling watt external diameter is to remedy through the position of adjustment radius stay in spoke during swelling.Present embodiment compresses the location that swelling watt realizes locking watt through holding screw, and is simple in structure, easy to operate.

In the present embodiment, the steel band outer baffle adopts plectane to add the structure that spoke adds inner ring, and the effect of spoke is equivalent to gusset.The steel band outer baffle also can adopt the structure of the outer ring+spoke+inner ring among the embodiment 1.

Embodiment 5:

See also Fig. 8, and the difference of embodiment 1 is: between first shaft shoulder of dish spring support ring 19 and pull bar, clamp adjusting disk 60, adjusting disk 60 is sleeved on the pull bar 17.Dish spring support ring 19 does not directly contact with first shaft shoulder 171 of pull bar; But contact with the adjusting disk that is used for size adjusting 60; The internal diameter of adjusting disk 60 is identical with the external diameter of pull bar 17; The external diameter of adjusting disk 60 is identical with the internal diameter of the first inner ring sleeve 21, and can endwisely slip between the first inner ring sleeve 21.

In process of production, the internal diameter of steel band material volume can not be completely unified, and the present invention depends on the locking cylinder of pulling pull bar and can move fully and put in place, utilizes lock in the cylinder to guarantee not take place the material volume accident that flies out.But the position of material volume internal diameter and pull bar pulling is to have certain relation of interdependence; If the internal diameter of material volume is bigger than theoretical value; After putting in place, the cylinder cylinder bar that causes driving pull bar still can't increase to the position; Also can't guarantee even discharge amount of compression once more, so just need the relative position of adjustment dish spring support ring and pull bar through belleville spring.For example, the position of dish spring support ring is outwards moved, then need increase the thickness or the quantity of adjusting disk, make cylinder when moving to the terminal, the external diameter of swelling watt is less than original steel coil strip internal diameter; Vice versa.Adjusting disk can have various ways: 1) to certain material volume internal diameter size; Calculate the every increase certain size of internal diameter (for example 1mm or 0.5mm); The thickness of needed adjusting disk; The internal diameter of corresponding a kind of material volume of the thickness of each adjusting disk when the internal diameter of steel coil strip changes to some extent, increases or reduces cooresponding adjusting disk number; Required size adjusting washer size when 2) calculating discharging volume internal diameter respectively and be different size is made the adjusting disk of coil diameter in corresponding each steel band respectively, when the internal diameter of steel coil strip changes to some extent, and integral replacing size adjusting packing ring.

Embodiment 6:

Among the embodiment 1; Swelling watts 7 is connected through the outdoor gusset 12 of swelling watt inner reinforced plate 8 and swelling connecting rod 10 and plain bearing; Swelling connecting rod one end and the outdoor gusset of plain bearing plane are hinged; The other end and swelling watt inner reinforced plate plane is hinged, and outdoor gusset of plain bearing and plain bearing chamber are connected, and swelling watt inner reinforced plate and swelling watt are connected.Under the constraint that does not have other, in the swelling plane of movement of swelling watt, the swelling connecting rod can carry out the swing of single degree of freedom with respect to the plain bearing chamber, and swelling watt can be that the swing in the plane is carried out at the center with the hole of swelling interlinking lever end.So with the plain bearing chamber is system of axes, swelling watt has two degree of freedom.So can claim to be connected for 2DOF between swelling watt and the plain bearing chamber.

In like manner, among the embodiment 1, a transverse plane of an end of two groups of support link 9 and swelling watt inner reinforced plate 8 is hinged, and outer gusset 11 planes of the other end and turnbarrel are hinged.Because two groups of support link are isometric, and swelling watt inner reinforced plate and two holes of two groups of support link pivotallys attached are and the outer gusset of turnbarrel and two holes of two groups of support link pivotallys attached, and pitch-row is the same, and this has just constituted parallel-crank mechanism.And the swelling watt mode with parallel-crank mechanism connects and turnbarrel, so swelling watt can only drive down in support link and swelling connecting rod with parallel with turnbarrel all the time mode, carries out parallel mobilely, and any rotation or swing do not take place for self.Its position only is decided by the angle between the outer gusset of support link and turnbarrel, so be connected for single degree of freedom between swelling watt and the turnbarrel.

So for 2DOF is connected, and be that 1 degree of freedom is connected between the turnbarrel between swelling watt and the plain bearing chamber, so connecting, the M degree of freedom described in the summary of the invention is connected with the N degree of freedom, M+N=3 is this notion.

Except embodiment 1 described swelling watt bracing or strutting arrangement, can also adopt following method for supporting:

First kind of mechanism:

Shown in figure 14, this figure is reduced to straight line for simplifying view with swelling connecting rod and support link; Every place hinge hole is reduced to circle, and among the figure, the plain bearing chamber watt links to each other through two groups of isometric swelling connecting rods and swelling; And swelling watt inner reinforced plate and two holes of two groups of support link pivotallys attached are and the outdoor gusset of plain bearing and two holes of two groups of support link pivotallys attached; Pitch-row is the same, constitutes parallel-crank mechanism, so swelling watt is that single degree of freedom is connected with the plain bearing chamber.And swelling watt is to be connected through one group of support link and the outer gusset of turnbarrel, and swelling watt is that 2DOF is connected with turnbarrel.In the breathing plane of movement of every tensioner watt, said swelling watt is connected with the plain bearing chamber with M degree of freedom ways of connecting, is connected with turnbarrel with N degree of freedom ways of connecting, and M is 1, and N is 2, and M+N=3.

In this structure; Though the weight of material volume is to be born jointly by tensioner connecting rod and support link, promptly some radial weight is born by the plain bearing chamber, shown in Fig. 1, Fig. 6 a and Fig. 6 b; The plain bearing chamber is when sliding into maximum distance; Still some length is embedded in the turnbarrel, and diametral load is born by turnbarrel, does not have the problem of utilizing two-direction thrust bearing to bear radial weight.

Second kind of mechanism:
