Description
Technical field
The utility model belongs to the uncoiling field of sheet metal strip, belongs to big group of the B21C47 of IPC classification number, also can be used for weaving, the uncoiling field of industries such as printing and dyeing, papermaking, plastics, particularly relates to initiatively unwinding and rewinding machine of a kind of unwinding and rewinding machine tightening device and both arms.
Background technology
At present, along with the fast development of flux-cored wire industry, flux-cored wire manufacturer more and more payes attention to reducing the non-cutting time of 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 decoiling unit " discloses the two reel decoiling units 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 baring; The running part of left and right reel and telescopic oil cylinder are fixed on the gyro-rotor simultaneously; The dead in line of the mandrel of telescopic oil cylinder and left and right reel is fixed on the top of gyro-rotor, and the casing of two cover reels is separately fixed at the both sides of gyro-rotor.Its two cover reels, intermittent use, when a reel normal operation, another reel can be gone up volume simultaneously, has omitted service working time, thereby has improved production efficiency, has not only reduced the floor area of manufacturing line, and has practiced thrift equipment investment.
The design of this decoiling unit is straight and narrow, and device such as brake gear, driving 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 personnel 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 structure, the cantilever beam structure of this and single armed decoiling unit is actually duplicate.The designer comes down to common single armed decoiling unit dos-is overlaped.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 load-carrying 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 gyro-rotor of both arms unreeling machine bigger, but should two cover running parts have been comprised by gyro-rotor, two cover reel parts, a cover telescopic section.On the one hand, but greatly increased the weight of the weight of gyro-rotor, 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 gyro-rotors 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 center 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 expansion type mechanism tensioning steel coil strip: wedge expansion 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 tensioning mode of this structure generally is applied on the decoiling unit of large-scale heavy duty.This decoiling unit 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 hypertonic of three-jaw; Wearing and tearing are big, need carry out specific surface treatment to friction face, cause the decoiling unit 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 decoiling unit of this tensioning mode extremely uneconomical, be unfavorable for promoteing the wider application.The tensioning mode often also needs the 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 actuating cylinder to realize the tensioning function of tensioning 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 tensioning watt will lose enough tensile forces.When tensioning watt loses enough tensile forces, for the machine of vertical unreeling/rolling, still can the material volume still can be positioned in the tensioning 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 have 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 tensioning watt have enough tensile forces to come the inboard of tensioning material volume; Watt can not withdraw and only satisfy tensioning; Be merely simple actv. bearing force but not the actv. tensile force between tensioning watt and the material volume inboard, be actually like this and open 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 tensioning watt also can't tensioning 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.

In the present embodiment, the connection structure of casing and base, similar with disclosed connection structure among the patent documentation CN201525655U, the utility model repeats no more at this.
The principle of work of present embodiment is:
One) before the lifting steel coil strip; The displacement cylinder group of respective side is shunk; Displacement cylinder drives pull bar through connecting panel and stretches out; Circlip for shaft on the pull bar promotes the first inner ring sleeve and the second inner ring sleeve, and 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 tension link and the axis reduces, and the angle between support link and the axis reduces simultaneously; Tensioning watt edge is that the circular arc of radius outwards moves with the distance between two hinge-points of support link and tension link, and the external diameter of tensioning simultaneously watt also dwindles thereupon.When the outer gusset of the inner reinforced plate of tensioning watt and turnbarrel contacted, the external diameter of tensioning 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 tensioning 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 tensioning 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 tensioning watt after tensioning, 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 tensioning 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 tensioning 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 tensioning 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,, and do not cause other variations so this moment, cylinder only was through pull bar compression belleville spring group.Certainly; If select the cylinder of less stroke for use in order to reduce the space in the casing, tensioning 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 tensioning watt; Can move plain bearing is outdoor through tension link, 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 tensioning watt inner reinforced plate segment distance that descends, and after one section of dish spring group compression, tensioning 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 tension link and support link tensioning watt is propped up, this moment, the center of gravity of steel coil strip constantly rose.
Since tensioning watt tensioning when putting in place tension link 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 tensioning 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 constantly its amount of compression.This moment, dish spring group still had certain compression surplus.So watt with steel coil strip after the complete tensioning, cylinder still continues to release a segment distance in tensioning, pull bar continues to shrink inwards, disc spring sleeve compression belleville spring group.Until reaching the cylinder stroke, cylinder in-to-in lock 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 belleville spring by the length of another compression in the tensioning watt length that the cylinder bar continues to stretch out after the complete tensioning with steel coil strip.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 unreeling machine operation on the dish spring group is also just more little.For above-mentioned reasons, in unwinding and rewinding machine when operation,, in other words, the axial force after the steel coil strip tensioning 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 tensile 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 tensioning process; Overcome tensioning watt needs and will expect that the center of gravity of volume rises on the needed gravity level, if the application force of disk spring is also only on this level during cylinder locking, that tensile 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 tensile force that can provide is only rolled up for material; Because the geometric relationship between tension link, tensioning watt, support link and the pull bar can not produce bigger tensile 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; And this tensile force can not disappear because of the gas leakage/leakage of cylinder, and this additional tension exactly, and guaranteeing can have enough friction force between tensioning 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, when tensioning watt will expect to roll up complete tensioning; Application force on the dish spring group is 800 kgfs; Because the second-compressed of dish spring group, the application force on the dish spring group has increased by 160 kgfs again, and tensioning watt is rolled up the tensile force that has increased by 200 kgfs between the inboard again with material so; The friction force that this has just increased between tensioning watt and the material volume inboard has improved the unwinding and rewinding machines control ability to material volume velocity variations.
Owing to adopt the decoiling unit or the winder of tensioning watt tensioning 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 tensioning watt to regulate its rotating speed through the friction force that tensioning watt and material are rolled up between the inner core; And friction force is by tensile force and friction coefficient decision; And friction coefficient be immobilize moving; So can only improve friction force through increasing tensile force, because described in the last paragragh, it is excessive that the tensile force of the unwinding and rewinding machine of existing employing tensioning watt form can not be done.And the technical scheme in the employing present embodiment; Raising tensile force that can be bigger; And then the unwinding and rewinding machine that improves employing tensioning 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 tensioning operation is accomplished; Outer baffle is contained in the tensioning 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 initiatively folding and unfolding band.
Four) when the steel coil strip of a side has been put; Step on stretcher, make its rotation, make limit shaft shifted laterally in the zigzag groove of upper limit cover; And then step on stretcher downwards; Stretcher overcomes the elastic force of spiral compression spring, drives limit shaft and in upper limit cover and lower limit cover, moves down, and withdraws from the spacing hole of the upper end of limit shaft from box bottom.And then stepping on stretcher and make it continue rotation; Make locating dowel pin shifted laterally in the zigzag groove of upper limit cover; Move to the right-hand part of the following horizontal stroke of zigzag, the top of locating dowel pin is stopped, so just can guarantee that locating dowel pin can upwards not skid off because of the elastic force of compression spring; Cause limit shaft upwards to stretch out, disturb the rotation of casing.Casing can be rotated then.After the casing rotation puts in place; Again according to opposite sequence control motion of foot, can make locating dowel pin come back to horizontal left side, zigzag top one, simultaneously; Drive limit shaft and in upper limit cover and lower limit cover, move up, the upper end of limit shaft is stretched in the spacing hole on the box bottom.Stop owing to have below this position, can not skid off that the phenomenon of having avoided limit shaft from spacing hole, to withdraw from effectively makes the casing location more reliable downwards so can guarantee locating dowel pin.
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 limiting stopper of pin joint.

Embodiment 4:
Be the registration device of outer baffle with the difference of embodiment 1.See also Figure 14～Figure 15; In the present embodiment; The registration device of outer baffle comprises and is sleeved on the outer locking of tensioning watt watts 53, is connected with the holding screw and the radius stay 54 that are pressed in the tensioning 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 tensioning 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 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 registration device of outer baffle into the locking that directly is sleeved in the tensioning watt watt; Locking watt shape and size and tensioning watt coupling; No matter how a tensioning watt formed circular outer diameter size changes, and the shape of tensioning watt itself is fixed, so locking watt can watt realize stable cooperating with tensioning.And the variation of tensioning watt external diameter is to remedy through the position of adjustment radius stay in spoke during tensioning.Present embodiment compresses the location that tensioning 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 16, 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 utility model 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; Still can't open after the cylinder cylinder bar that causes driving pull bar puts in place and put in place; 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 tensioning 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.
Although combine accompanying drawing that the preferred embodiment of the utility model is described above, the utility model is not limited to the above-mentioned specific embodiment, and the above-mentioned specific embodiment only is schematic; Be not restrictive; Those of ordinary skill in the art not breaking away under the scope situation that the utility model aim and claim protect, can also make a lot of forms under the enlightenment of the utility model; 1. replace tensioning watt inner reinforced plate described in the utility model and the outer gusset of turnbarrel with hinged-support; Be installed in the inboard of tensioning watt and the outside of turnbarrel respectively, and hinged, play the effect of supporting tensioning watt with support link; The cylinder number that 2. will be used to strut each side tensioning watt changes 3 or more number into, and the cylinder that supports both direction still is crisscross arranged; 3. with parts that have identical function among the above embodiment or unit construction mutual alternative, constituting does not have the directly technical scheme of description among above each embodiment, and these all belong within the protection domain of the utility model.
