Description
Technical field
The invention belongs to the uncoiling field of sheet metal strip, belong to big group of the B21C47 of IPC classification number, also can be used for weaving, the uncoiling field of industry such as printing and dyeing, papermaking, plastics, particularly relate to a kind of one-sided unreeling machine and one-sided unwinding and rewinding machine.
Background technology
At present, along with the fast development of flux-cored wire industry, flux-cored wire manufacturer more and more payes attention to the non-cutting time of minimizing equipment operation, to enhance productivity.Wherein reducing each required time of replacing steel coil strip is one of them important means with changing frequency.Use exoskeletal accurate after-combustion steel coil strip to unreel so emerged in recent years, this steel coil strip can directly utilize steel band itself to form steel coil strip, and after steel band all discharged, what was not remaining on the unreeling machine, can directly put new steel coil strip again.Also can adopt the inner tube of a tyre of paper web as steel coil strip, steel band back and forth is wrapped on the paper web, forms steel coil strip, and after steel band all discharged, from unreeling machine collection last time tube, paper web can also be used for twining again new steel band.Make and carry out unwinding and rewinding in this way and not only reduced the workman and push to, push the time and the labour intensity of I-beam wheel, and when having solved I-beam wheel as the carrier of steel coil strip, the turnover problem of I-beam wheel and the consumption problem of I-beam wheel.
But existing both arms are put the band machine and are had plenty of the repeated combination of existing single head being put the band machine, and for example CN201105294Y " two reel uncoiler " discloses the two reel uncoilers in a kind of cold-strip steel uncoiling field, and it contains two cover running parts; Two cover reel parts; One cover telescopic section is divided into rotating part, and the mandrel in the main shaft of left and right reel links to each other respectively with the cylinder bar of telescopic oil cylinder through a pair of thrust bearing; The running part of left and right reel and telescopic oil cylinder are fixed on the revolving body simultaneously; The dead in line of the mandrel of telescopic oil cylinder and left and right reel is fixed on the top of revolving body, and the casing of two cover reels is separately fixed at the both sides of revolving body.Its two cover reels, discontinuous operation, when a reel operate as normal, another reel can be gone up volume simultaneously, has omitted service working time, thereby has improved production efficiency, has not only reduced the floor space of production line, and has practiced thrift equipment investment.
The design of this uncoiler is straight and narrow, and device such as brake gear, transmission device is available in all varieties, but wherein the main shaft of reel leans on bearing fixing on casing.This equipment is with (though the not directly explanation in the literary composition of two self-aligning roller bearings; But the technical staff in this area can be from Figure of description unquestionable definite bearing type) be installed on two risers of casing; And main shaft and reel (promptly bearing the steel coil strip weight of portions) lean out casing; Formed cantilever beam structures, the cantilever beam structures of this and single armed uncoiler is actually duplicate.The designer comes down to common single armed uncoiler is overlaped back-to-back.Caused in other words conj.or perhaps apart from the bearing part nearer shaft strength nearer very big like this apart from reel.For addressing this problem, or use the strongly-typed bearing of bearing capacity instead, or use larger sized bearing instead, the two all can increase the manufacturing cost of equipment; Be cost just to sacrifice bearing life.
But and adopt this structure will cause the length of revolving body of both arms unreeling machine bigger, but should two cover running parts have been comprised by revolving body, two cover reel parts, a cover telescopic section.On the one hand, but greatly increased the weight of the weight of revolving body, just can find out from two huge gussets (limit switch of each side promptly is installed on the gusset), if not so big casing, so heavy casing need not so big gusset so and supports.Thereby make that utilizing manpower to turn round becomes impossible, so but just must cause it to need above-mentioned these revolving bodies of motor-driven to turn round, and then the another step has caused the complicacy of equipment.On the other hand; This structure makes that reel is that the main bearing part and the distance of the centre of gyration have increased greatly; Part that will be heavier shifts out the scope that base contacts with ground outward, if the steel coil strip of having only a side on unreeling machine, and the steel coil strip of opposite side has used up; The equipment center of gravity that has comprised steel coil strip so will deflect away from the support scope of base, so will improve the risk that equipment topples greatly like this.
In addition; This unreeling machine adopts wedge expanding-contracting type mechanism tensioner steel coil strip: wedge expanding-contracting type mechanism comprises a three-jaw inclined wedge-shaped structure; Oblique bloated piece is connected with the dovetail shaped drift slot with interior wedge; In moving wedge can promote that oblique bloated piece opens or oppositely move in wedge make oblique bloated piece withdrawal, and can realize self-locking through the wedge angle, the interior tensioner mode of this structure generally is applied on the uncoiler of large-scale heavy duty.This uncoiler all is to adopt cantilever structure, and in order to guarantee to bear heavier coil of strip, what be used for that the main shaft of load-bearing will do is thick; In addition, process oblique bloated piece and interior wedge and bother very much, and slide by the inclined-plane and to realize the harmomegathus of three-jaw; Wearing and tearing are big, need carry out specific surface treatment to rubbing surface, cause the uncoiler of this large-scale heavy duty to cost an arm and a leg; Bulky, this shows, for the lighter situation of coil of strip; Adopt the uncoiler of this tensioner mode extremely uneconomical, be unfavorable for promoteing the wider application.The tensioner mode often also needs interpolation lubricating oil to safeguard in this, otherwise very easily wears away the inclined working of oblique bloated piece and interior wedge, causes shorten service life.
And, in existing rolling/unreeling machine,, all do not have auto-lock function if there is employing cylinder/hydraulic cylinder to realize the tensioner function of tensioner watt.That is, when cylinder/hydraulic cylinder or the gas circuit that is connected with it/fluid pressure line took place to reveal, the air pressure or the hydraulic pressure that act in the cylinder body on the piston descended, and tensioner watt will lose enough expanding forces.When tensioner watt loses enough expanding forces, for the machine of vertical unreeling/rolling, still can the material volume still can be positioned on the tensioner 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 security incident or causes serious wastage of material.
If but the cylinder/hydraulic cylinder that will have auto-lock function simply is applied to and unreels/the winder field; Can have following problem again: 1, the self-locking of cylinder/hydraulic cylinder only is to keep the position of actuating strut motionless; And can't guarantee to provide a lasting constantly active force to make tensioner watt have enough expanding forces to come the inboard of tensioner material volume; Watt can not withdraw and only satisfy tensioner; Be merely simple passive support force but not expanding force initiatively between tensioner 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 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 cylinder to put in place after, self-locking device starts; It is inboard that tensioner watt also can't tensioner material volume, also still should have more than is needed self-locking cylinder/hydraulic cylinder.
So self-locking cylinder/hydraulic cylinder is applied to unreel/the winder field, avoid leaking gas or leakage to the influence of machine safety in operation and reliability, be that those skilled in the art thirsts for solving and the problem of failing to succeed always.

In sliding bearing chamber 13; From the inner; Be provided with the two-direction thrust bearing 20, dish spring support ring 19, disk spring group 18 and the disc spring sleeve 15 that are sleeved on successively on the pull bar 17, disk spring group 18 is contained in the disc spring sleeve 15, and disc spring sleeve is a bowl-type; The bottom of bowl is sleeved on the pull bar, and disc spring sleeve 15 is positioned at the outside and the opening of two-direction thrust bearing 20 towards two-direction thrust bearing 20; The outer end of pull bar 17 passes the bottom of disc spring sleeve 15 and is provided with one section external screw thread, is connected with nut 16 on the screw thread of pull bar outer end, the bottom outside adjacency of nut 16 and disc spring sleeve 15.
The inner ring of two-direction thrust bearing 20 is installed between the first inner ring sleeve 21 and the second inner ring sleeve 22.The first inner ring sleeve 21 to be can being sleeved on the pull bar 17 along the modes that pull bar 17 axially outwards slides, and be bigger matched in clearance between the pull bar 17, causes unnecessary wearing and tearing to avoid the first inner ring sleeve 21 and pull bar 17 to come in contact.The second inner ring sleeve, 22 suits are fixed on the first inner ring sleeve 21.The Outboard Sections of the first inner ring sleeve, 21 outer walls is provided with a step surface, and this step surface props up the outside of two-direction thrust bearing 20 inner rings, and the lateral surface of the second inner ring sleeve 22 props up the inboard of two-direction thrust bearing 20 inner rings.The outer ring of two-direction thrust bearing 20 is installed in the sliding bearing chamber 13, and the outer end of sliding bearing chamber 13 is connected with bearing (ball) cover 14 through bolt, and this bearing (ball) cover 14 is a tubular construction, and the outer end of tubular is provided with flange, is used for being connected with the outer face of sliding bearing chamber; The inner of tubular props up the outer ring, the outside of two-direction thrust bearing 20, is used for the location of this outer ring.
Also be provided with a circlip for shaft 23 on the pull bar 17, circlip 23 is positioned at the inboard of the first inner ring sleeve 21 and the second inner ring sleeve 22, is used to promote the first inner ring sleeve 21 and the second inner ring sleeve 22.Before each material loading; Pull bar is outwards released; Make the support reduction device outwards move, and then drive tensioner through the tensioner connecting rod and watt close up and to go up volume, because required thrust is little with convenient; So on pull bar, be provided with a circlip for shaft 23, the installation site of this circlip for shaft 23 is the inboard of tensioner first inner ring sleeve 21 when watt strutting fully.When pull bar 17 moves laterally; Circlip 23 promotes two-direction thrust bearing 20 through the first inner ring sleeve 21 and the second inner ring sleeve 22, and two-direction thrust bearing 20 promotes sliding bearing chamber 13 through bearing (ball) cover 14, makes sliding bearing chamber 13 outer moving; Outwards move the lower end that drives tensioner connecting rod 10; Watt 7 downward translations of tensioner connecting rod 10 pulling tensioner, the closing up of completion tensioner watt is so that the smooth installation of steel coil strip.
When pull bar 17 moves to the inside; Nut 16 through being threaded in its end promotes disc spring sleeves 15, disc spring sleeve 15 with force transmission on disk spring group 18, the 18 stressed contractions of disk spring group; Be delivered to active force on the first inner ring sleeve 21 that is connected with two-direction thrust bearing 20 through dish spring support ring 19; The first inner ring sleeve 21 passes to sliding bearing chamber 13 through two-direction thrust bearing 20 with power, and move to the inside sliding bearing chamber 13, and the lower end that drives tensioner connecting rod 10 moves inward; Tensioner connecting rod 10 promote tensioners watts 7 upwards translation open, accomplish the tensioner process of material volume.
The length of above-mentioned disc spring sleeve 15 should guarantee when butterfly spring group 18 does not stress fully; Distance between the bottom inside of disc spring sleeve 15 and the two-direction thrust bearing 20 is greater than the decrement of butterfly spring; In order to avoid butterfly spring group 18 contacts with two-direction thrust bearing 20 because of disc spring sleeve 15 when compression, the problem that butterfly spring group 18 can't continue to compress occurs.
The supporting structure of above-mentioned turnbarrel 27 is selected single thrust bearing for use; Select the structure of two-direction thrust bearing in the support and contracting mechanism for use; Be because in actual production process; Tensioner watt impossible tensioner can only tensioner arrive the position shown in the first half of Fig. 6 left side to angle as shown in Figure 1, and the size that this part is represented is the theoretical internal diameter that material is rolled up.If tensioner is to angle shown in Figure 1, i.e. the axis normal of support link and pull bar 17, so tensioner watt tensioner to full-size.At the internal diameter size of steel coil strip during greater than theoretical size, that tensioner watt just can't the tensioner steel coil strip or has been tied with the inner tube of a tyre paper web of steel band.So tensioner watt in fact can not tensioner to full-size; Should keep one less than 90 ° angle with axis; Maintain enough frictional force for the weight of bearing steel coil strip and to innermost layer steel band or paper web like this; Support link and tensioner connecting rod just produce an axial force to corresponding gusset, and are delivered on sliding bearing chamber 13 and the turnbarrel 27, make the two that relative trend that expands outwardly arranged respectively; Therefore in the supporting structure of turnbarrel 27 with in the support and contracting mechanism, all should adopt thrust bearing to this trend, this thrust bearing can bear the axial force that this trend produces.Again because; When the thrust bearing in the support and contracting mechanism also will bear pull bar and outwards moves; The second inner ring sleeve 22 imposes on its outside active force; Therefore the thrust axis in the sliding bearing chamber 13 are promised to adopt and can be born the two-direction thrust bearing of bi-directional axial load in the support and contracting mechanism, and the block bearing of turnbarrel 27 adopts single thrust bearing to get final product.
Present embodiment is not limited to the said structure form to the installation form of above-mentioned two-direction thrust bearing 20 and the force transferring structure of pull bar 17; Also can adopt other mounting structure and force transferring structure; See also Fig. 7; The inner ring of two-direction thrust bearing is installed on the first inner ring sleeve 21; The first inner ring sleeve 21 to be can being sleeved on the pull bar 17 along the modes that pull bar 17 axially outwards slides, and with interior and be provided with second shaft shoulder 172 that is used for inwardly holding out against the two-direction thrust bearing inner ring, dish spring group 18 acts on elastic force on the outer face of the first inner ring sleeve 21 through dish spring support ring 19 the first inner ring sleeve 21 indirectly in the outer outer ring of two-direction thrust bearing 20.Said structure also can be cancelled dish spring support ring 19, and dish spring group 18 directly acts on elastic force on the outer face of the first inner ring sleeve 21.Pull bar 17 is provided with second shaft shoulder that is used for outwards promoting two-direction thrust bearing 20, and this second shaft shoulder should be positioned at the inboard of the inner ring of two-direction thrust bearing 20.
See also Fig. 1 and Fig. 8, in the present embodiment, the afterbody of 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; The middle part of lever 35 is hinged with the bearing 63 that is fixed on the casing riser, is connected with the casing riser and the pull bar 17 homonymy settings of bearing 63.
See also Fig. 9; Form second kind of structure that two cylinder 33 of one group are connected with pull bar: 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 the 2nd Y joint 36 hinged junctions, end and non-circular hole will cause lever to rotate otherwise the connection between the three is the structure of " bearing pin+circular hole ".
The connection wye 34 that is connected with pull bar 17 inner ends adopts the locking nut locking that is connected on the pull bar 17, between locking 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 lever, and lever 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.
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 locating ring 29, and Internal baffle locating ring 29 is fastened on the drive socket 28 through screw.
Because exoskeletal accurate after-combustion steel coil strip is on lifting unreeling 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 tensioner watt outwards, axial direction moves to machine intimate, the movement locus of steel coil strip and the tensioner 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 tensioner watt, and also the frictional force of relative motion is bigger; One deck or which floor steel band in the inner end edge of tensioner 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 on the tensioner watt, just need have a location device this moment on tensioner watt, to control steel coil strip in axial position.
See also Fig. 1, in the present embodiment, tensioner watt inner reinforced plate 8 is provided with inboard positioner 37, and inboard positioner is installed in the end of tensioner watt gusset near casing.Inboard positioner comprises two connection boards that are installed in tensioner watt gusset both sides; Connection board is L shaped; The connecting portion that the horizontal bottom conduct is connected with tensioner watt gusset, vertically portion is as the location division, and the connecting portion of connection board is provided with horizontal slotted hole; Be provided with the dog screw of connection board in the horizontal slotted hole, dog screw is fixed together a connection board and a tensioner watt gusset.Through moving horizontally the horizontal relative position of connection board control itself and dog screw; Can adjust the relative position of inboard positioner and tensioner watt; Guarantee steel coil strip after fully by tensioner, 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 and Fig. 5, locate in like manner with the inboard, the arranged outside of unreeling machine has outside positioner, and outside positioner is a demountable structure.Outside positioner comprises steel band outer baffle and outer baffle positioner; 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 positioner comprises two guide posts 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 backstay 384; Two guide posts 392 respectively are fixed on the outer circumference surface of turnbarrel 27 through riser 391, and two guide posts 392 are installed on respectively in two abutment sleeves 385, and the end of guide post 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.
Except taking above-mentioned setscrew nut as the retention mechanism of outer baffle on its guider, also can adopt other fastening means, for example on abutment sleeve, be provided with an eccentric wheel hold-down mechanism, realize fastening function.Or fastening abutment sleeve of jackscrew and outer baffle guide post are set on abutment sleeve.
Present embodiment is fixed with brake disc 6 in the inner of drive socket 28, and brake disc also is provided with many disc brake brakes 5 perpendicular to the axis of turnbarrel on the casing, and brake disc is between two braking planes of disc brake brake.Damping unit in the time of can selecting for use the less disc brake brake of air pressure normally to move as unreeling machine keeps a suitable tension force on the feasible steel band that is discharged.Select for use the bigger one or more disc brake brakes of air pressure as brake apparatus.
The brake disc of in present embodiment, being mentioned, can also select damping and the brake apparatus of cartridge type brake gear for use as unreeling machine.
The operation principle of present embodiment is:
One) before the lifting steel coil strip; The displacement cylinder group is shunk, and displacement cylinder stretches out through the lever drives pull bar, 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 bearing (ball) cover through two-direction thrust bearing.Because bearing (ball) cover and sliding bearing chamber are connected; The sliding bearing chamber is also along with bearing (ball) cover outwards moves together; The outdoor gusset of sliding bearing that is packed on the sliding bearing chamber also outwards moves thereupon together, and the angle between tensioner connecting rod and the axis reduces, and the angle between support link and the axis reduces simultaneously; Tensioner watt edge is that the circular arc of radius outwards moves with the distance between two pin joints of support link and tensioner connecting rod, and the external diameter of tensioner watt also dwindles thereupon simultaneously.When the outer gusset of the inner reinforced plate of tensioner watt and turnbarrel contacted, the external diameter of tensioner watt was retracted to minimum of a value, and cylinder still possibly not shunk and put in place this moment.
Because the axial location of inboard positioner on tensioner watt gusset can be regulated, so before the lifting steel coil strip, need adjustment to confirm the position of inboard positioner.If directly steel coil strip is placed on the tensioner 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 tensioner watt after tensioner, 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 positioner 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 tensioner watt support; For the steel coil strip that does not have paper web, this is with steel strip surface the most inboard in the heavy 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 tensioner watt relatively moved, frictional force needed the active force of cylinder to overcome, and undoubtedly can increase the load of cylinder, might cause the increase of cylinder size.After having increased inboard positioner, 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 tensioner watt goes up and axial location after, cylinder is stretched out, through the withdrawal of lever drives pull bar, the nut of tie rod end compresses disc spring sleeve, disc spring sleeve compression butterfly spring group.Because the butterfly spring group is not in compressive state when pull bar stretches out fully little when decrement will be more than the lifting steel coil strip in other words,, and do not cause other variations so this moment, cylinder only was through pull bar compression butterfly spring group.Certainly; If select the cylinder of less stroke for use in order to reduce the space in the casing, tensioner 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 on the tensioner watt; Can move sliding bearing is outdoor through the tensioner connecting rod, through two-direction thrust bearing, the first inner ring sleeve, dish spring support 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 tensioner watt inner reinforced plate segment distance that descends, and after one section of dish spring group compression, tensioner 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 compression stress suffered on the butterfly spring group reaches need steel coil strip be risen required active force the time; The sliding bearing chamber is (this power is delivered on the sliding bearing chamber through dish spring support ring and two-direction thrust bearing) under the elastic force effect of butterfly spring; In turnbarrel, move; And then through tensioner connecting rod and support link tensioner watt is propped up, this moment, the center of gravity of steel coil strip constantly rose.
Since tensioner watt tensioner when putting in place tensioner 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 (butterfly spring stressed) during tensioner on the connecting rod is less than the power when just beginning the lifting steel coil strip; The length of butterfly spring is greater than its length when just beginning the lifting steel coil strip; In lifting the process of steel coil strip, butterfly spring comes down to discharge constantly its decrement.This moment, dish spring group still had certain compression surplus.So watt with steel coil strip after the complete tensioner, cylinder still continues to release a segment distance in tensioner, pull bar continues to shrink inwards, disc spring sleeve compression butterfly spring group.Until reaching the cylinder stroke, the inner lock of cylinder with lock is locked cylinder, prevents that cylinder from losing thrust because of gas leakage, causes expecting to roll up the accident that flies out.Be butterfly spring by the length of another compression in the tensioner watt length that the cylinder bar continues to stretch out after the complete tensioner with steel coil strip.When parts such as cylinder, lever, 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 unreeling machine operation on the dish spring group is also just more little.For above-mentioned reasons, in unreeling machine when operation,, in other words, the axial force after the steel coil strip tensioner is less, and after machine run got up, the two-direction thrust bearing in the outside and inboard thrust bearing stressed also less helped improving the thrust bearing life-span.
The generation of second-compressed amount is not only in order to remedy the error when installing, and has the effect that expanding force is provided concurrently.If because there is not second-compressed; Elastic force on the disk spring also only is to rest on because in the material volume tensioner process; Overcome tensioner watt needs and will expect that the center of gravity of volume rises on the needed gravity level, if the active force of disk spring is also only on this level during cylinder locking, that expanding force to the material volume will be the same (when not using dish spring group with not using dish spring group; The gravity that the expanding force that can provide is only rolled up for material; Because the geometrical relationship between tensioner connecting rod, tensioner watt, support link and the pull bar can not produce bigger expanding 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 expanding force; And this expanding force can not disappear because of the gas leakage/leakage of cylinder, and this additional expanding force exactly, and guaranteeing can have enough frictional force between tensioner 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 security and the reliability of system.For example, the weight of material volume is 1000 kilograms, when tensioner watt will expect to roll up complete tensioner; Active force on the dish spring group is 800 kgfs; Because the second-compressed of dish spring group, the active force on the dish spring group has increased by 160 kgfs again, and tensioner watt is rolled up the expanding force that has increased by 200 kgfs between the inboard again with material so; The frictional force that this has just increased between tensioner watt and the material volume inboard has improved the unwinding and rewinding machines control ability to material volume velocity variations.
Owing to adopt the uncoiler or the winder of tensioner watt tensioner 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 rotary 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 tensioner watt to regulate its rotating speed through the frictional force that tensioner watt and material are rolled up between the inner core; And frictional force is by expanding force and coefficient of friction decision; And coefficient of friction be immobilize moving; So can only improve frictional force through increasing expanding force, because described in the last paragragh, it is excessive that the expanding force of the unwinding and rewinding machine of existing employing tensioner watt form can not be done.And the technical scheme in the employing present embodiment; Raising expanding force that can be bigger; And then the unwinding and rewinding machine that improves employing tensioner watt form is rolled up the control ability of velocity variations to material; Acceleration that needs are bigger in the time of can adapting to speed governing and/or material are rolled up the bigger occasion of rotary inertia, have expanded the scope of application of such machine.
Three) after the tensioner operation is accomplished; Outer baffle is contained on the tensioner watt; Utilize two abutment sleeves and two guide posts 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 check 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, for example resilient sleeve etc.Nut 16 can be replaced by the limited block of pin joint.
Embodiment 2:
Be with the difference of embodiment 1, changed the connected 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.
First kind of structure: see also Figure 10; 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; The other end of lever 35 is hinged with the bearing 61 that is fixed on the casing riser, and bearing 61 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 tensioner watt radius is reduced; When cylinder was shunk, pull bar moved to box house, made tensioner watt spreading to setting diameter.
Second kind of structure: see also Figure 11; 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 the hinged junction, end of a Y joint 34 with the 2nd Y joint 36 hinged junctions, middle part and non-circular hole will cause lever to rotate otherwise the connection between the three is the structure of " bearing pin+circular hole ".
Embodiment 3:
Seeing also Figure 12, still is example with the left-half, compares with embodiment 1; Dish spring and disc spring sleeve structure in the sliding bearing chamber 13 have been cancelled; Two-direction thrust bearing is directly installed on the pull bar, and the inboard that the outer end of pull bar is provided with the 3rd shaft shoulder 52, the three shaft shoulders 52 props up the inner ring of two-direction thrust bearing 20; The opposite side of inner ring is propped up by the first inner ring sleeve 51, and the first inner ring sleeve 51 is fastened on the pull bar 17 through screw.Sliding bearing chamber 13 is no longer inner at turnbarrel when flexible, but is directly installed on the turnbarrel outside, when the cylinder bar moves, directly drives the sliding bearing chamber and moves back and forth, and need not through dish spring transfer function power.
Under the identical situation of tensioner watt length (being machine-wide); The outer end supporting structure that the structure of present embodiment can make turnbarrel is more near the outer end of turnbarrel; Load proportion between the equalizer bearing better; The bearing capacity of this load proportion and bearing is complementary, realizes that bearing life is tending towards unified more, reduced the overhaul frequency.But adopt this structure to need the higher precision of being equipped with of cylinder, when making the steel coil strip tensioner, the position of cylinder bar in cylinder for the position of cylinder locking, need not the dish spring and remedies rigging error just.
For embodiment 1; For the length that reduces the unreeling machine single armed sliding bearing chamber is contained in the turnbarrel; Therefore caused the outer end supporting structure of turnbarrel nearer apart from the center of gravity of steel coil strip; Cause the suffered load of bearing in the inside and outside end bearing structure of turnbarrel to differ greatly, bigger with the theory load gap of bearing, finally caused the inharmonious of bearing life.For unified bearing life; Can increase the length of tensioner watt, make that sliding bearing is outdoor to be moved, to increase the distance between turnbarrel outer end supporting structure and the steel coil strip center of gravity; Make the real load ratio and the bearing capacity of inside and outside end bearing bearing mate more, thus unified bearing life.But this structure except equalizer bearing the life-span, has no other good effect; On the contrary; Cause unreeling machine single armed length to increase, increased material consumption, improved the manufacturing cost of equipment; But also increased the rotary inertia of rotating part simultaneously, improved the labor load of the manual rotating box of workman.
Embodiment 4:
Be the positioner of outer baffle with the difference of embodiment 1.See also Figure 13～Figure 14; In the present embodiment; The positioner of outer baffle comprises and is sleeved on the outer locking of tensioner watt watts 53, is connected with the holding screw and the backstay 54 that are pressed on the tensioner watt in the locking watts 53, and backstay 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 backstay.Locking watt compresses tensioner through the holding screw on it and watt realizes locking, and backstay compresses spoke through the lock-screw on it and realizes the location.
Above-mentioned outer baffle positioner can be avoided the big problem of embodiment 1 outer baffle positioner difficulty of processing.Because in embodiment 1, outer baffle and turnbarrel are except the nested relationship of abutment sleeve and guide post; Be two incoherent parts fully; And the outer baffle guide post 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 guide post; Increasing fit clearance needs to guarantee installation, thus, has improved the unstability of outer baffle location; The raising machining accuracy increases processing cost.The two scheme all has certain drawback.
Outer baffle positioner among the embodiment 1; Owing to be provided with the outer baffle guide post in the end of riser; Guide post is in a single day stressed, for riser, is a cantilever beam structures of only having fixed at afterbody; And outer baffle guide post itself also is a cantilever beam structures 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 structures; Can reduce the height of riser; If but reduced height, just need to increase the length of backstay in the outer baffle positioner, and backstay itself also would be a cantilever beam structures; If increase the length of backstay, certainly will reduce its rigidity and bearing capacity again.And outer baffle is after being put into the material volume on the unreeling machine; Be manually installed on the unreeling 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 positioner of outer baffle into the locking that directly is sleeved on the tensioner watt watt; Locking watt shape and size and tensioner watt coupling; No matter how a tensioner watt formed circular outer diameter size changes, and the shape of tensioner watt itself is fixed, so locking watt can watt realize stable cooperating with tensioner.And the variation of tensioner watt external diameter is to remedy through the position of adjustment backstay in spoke during tensioner.Present embodiment compresses the location that tensioner 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 Figure 15, and the difference of embodiment 1 is: between first shaft shoulder of dish spring support ring 19 and pull bar, clamp adjustment packing ring 60, adjustment packing ring 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 adjustment packing ring 60 that is used for size adjusting; The internal diameter of adjustment packing ring 60 is identical with the external diameter of pull bar 17; The external diameter of adjustment packing ring 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 decrement once more, so just need the relative position of adjustment dish spring support ring and pull bar through butterfly spring.For example, the position of dish spring support ring is outwards moved, then need increase the thickness or the quantity of adjustment packing ring, make cylinder when moving to the terminal, the external diameter of tensioner watt is less than original steel coil strip internal diameter; Vice versa.The adjustment packing ring 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 adjustment packing ring; The internal diameter of corresponding a kind of material volume of the thickness of each adjustment packing ring when the internal diameter of steel coil strip changes to some extent, increases or reduces corresponding adjustment packing ring number; Required size adjusting washer size when 2) calculating discharging volume internal diameter respectively and be different size is made the adjustment packing ring 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.
