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 single head.
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.

Because exoskeletal accurate after-combustion steel coil strip is on lifting the unwinding and rewinding machine 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 tensioning watt outwards, axial direction moves to machine intimate, the path of motion of steel coil strip and the tensioning 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 tensioning watt, and also the friction force of relative motion is bigger; One deck or which floor steel band in the inner end edge of tensioning 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 tensioning watt, just need have a location device this moment in tensioning watt, to control steel coil strip in axial position.
See also Fig. 1, in the present embodiment, tensioning watt inner reinforced plate 8 is provided with inboard registration device 37, and inboard registration device is installed in the end of tensioning watt gusset near casing.Inboard registration device comprises two connection boards that are installed in tensioning watt gusset both sides; Connection board is L shaped; Horizontal bottom conduct and tensioning 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 tensioning 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 tensioning watt; Guarantee steel coil strip after being tensioned fully, its inside edge can contact with the square tube of Internal baffle assembly, realizes the location of steel band.
See also Fig. 3, Fig. 4 a and Fig. 4 b, locate in like manner with the inboard, 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.
Except taking above-mentioned setscrew nut as the fastening device of outer baffle on its guide piece, 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 pilot bar 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 drgs 5 perpendicular to the axis of turnbarrel on the casing, and brake disc is between two braking planes of disc brake drg.Damping arrangement in the time of can selecting for use the less disc brake drg of air pressure normally to move as the unwinding and rewinding machine keeps a suitable tension force on the feasible steel band that is discharged.Select for use the bigger one or more disc brake drgs of air pressure as brake equipment.
The brake disc of in present embodiment, being mentioned, can also select damping and the brake equipment of cartridge type brake gear for use as the unwinding and rewinding machine.
The principle of work of present embodiment is:
One) when the workman need put a steel coil strip on double end unwinding and rewinding machine; Before the lifting steel coil strip, should guarantee that damping arrangement or brake gear clamp brake disc (otherwise turnbarrel will rotate with pull bar), manually rotate pull bar; The worm drive that pull bar leading screw section and bolster inner bolt hole form; The supporting sleeve that is axially fixed on the pull bar is moved outward, 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.
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, the application force that friction force need rotate pull bar overcame, and undoubtedly can increase working strength of workers, might cause manually rotating the pull bar difficulty.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; Manual contrarotation pull bar; The worm drive that pull bar leading screw section and bolster inner bolt hole form move inward the supporting sleeve that is axially fixed on the pull bar, and supporting sleeve drives tensioning through tension link and watt outwards opens.
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.
Embodiment 2:
Be the registration device of outer baffle with the difference of embodiment 1.See also Fig. 5~Fig. 6; 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 unwinding and rewinding machine; Be manually installed on the 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 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.
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; For example; 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.
