Above-mentioned support and contracting mechanism comprises that the inner is positioned at rotation hollow shaft 27 ports and outer end is positioned at the telescopic 13 rotating outside this port of hollow shaft, and this telescopic 13 is in axial sliding connection with rotating hollow shaft 27, and internal-and external diameter cooperatively interacts, and relative rotation does not circumferentially occur.On excircle, have a pillow block in the outer end of telescopic 13, the inner of restriction telescopic 13 puts in the degree of depth of rotating hollow shaft 27.The part that telescopic 13 is positioned at outside port is that outer end portion is provided with outer gusset, between telescopic 13 and every breathing arc plate inner reinforced plate 8, be equipped with swelling connecting rod 10, one end of swelling connecting rod 10 and breathing arc plate inner reinforced plate 8 are hinged, and the other end is hinged on the outer gusset 12 of telescopic.The swelling connecting rod 10 being connected with same breathing arc plate inner reinforced plate and support link 9 are positioned at same plane and are splayed arranges.
In telescopic 13, be provided with successively two-direction thrust bearing 20, dish spring group 18 and limiting component from outer end to the inner, limiting component is the second pillow block 91 of inner side, telescopic the inner, breathing draw bar 17 is provided with first pillow block 95, first pillow block props up the outer face of two-direction thrust bearing inner ring, and the outer ring of two-direction thrust bearing is arranged in swelling bearing outer sleeve 93.
The inner ring of two-direction thrust bearing 20 is arranged between first pillow block 95 and the flexible bearing inner sleeve 22 of second.Flexible bearing inner sleeve 22 suits of second are fixed on breathing draw bar, and the outer face of the flexible bearing inner sleeve 22 of second props up the inner side of two-direction thrust bearing 20 inner rings.
Swelling bearing outer sleeve is sleeved on telescopic inside face in the mode that can axially inwardly slide along telescopic with respect to telescopic, and between the inwall of telescopic, be larger free-running fit, cause unnecessary wearing and tearing to avoid swelling bearing outer sleeve 93 and breathing draw bar 17 to come in contact.The inner end portion of swelling bearing outer sleeve 93 inwalls is provided with third pillow block 90, and this third pillow block props up the inner end surface of the outer ring of the inner end of two-direction thrust bearing 20.The outer ring of two-direction thrust bearing 20 is arranged in telescopic 13, and the outer end of swelling bearing outer sleeve 93 is connected with roller bearing end cap 14 by bolt, and this roller bearing end cap 14 is a tubular construction, and the outer end of tubular is provided with flange, for being connected with the outer face of telescopic; The inner of tubular props up the outer ring, outside of two-direction thrust bearing 20, for the location of this outer ring.
Telescopic is provided with the force application structure for prop up swelling bearing outer sleeve to the inner, and this force application structure is the circlip for bore 92 being arranged on telescopic inwall;
Circlip for bore 92 is positioned at the position of comparatively outer end on telescopic inwall, for being promoted telescopic by swelling bearing outer sleeve 93.Before each material loading, breathing draw bar is extrapolated, support reduction device is outwards moved, and then drive breathing arc plate to close up to facilitate upper volume by swelling connecting rod, because required thrust is little, so be provided with a circlip for bore 92 on sliding, the installation site of this circlip for bore 92 is the outer end of breathing arc plate swelling bearing outer sleeve 21 while strutting completely.In the time that breathing draw bar 17 moves outward, be packed in the flexible bearing inner sleeve of second on breathing draw bar by application force successively the outer ring of the outer end of inner ring, roller or the ball by two-direction thrust bearing, two-direction thrust bearing be delivered on roller bearing end cap, promoting swelling bearing outer sleeve by roller bearing end cap 14 moves outward, and make to move outside telescopic 13 by circlip for bore 92, drive the lower end of swelling connecting rod 10 outwards to move, swelling connecting rod 10 pulls the downward translation of breathing arc plate 7, complete closing up of breathing arc plate, so that the smooth installation of steel coil strip.

The supporting structure of above-mentioned rotation hollow shaft 27 is selected one direction thrust bearing, selects the structure of two-direction thrust bearing in support and contracting mechanism, is because in actual production process, and breathing arc plate can not swelling arrive angle as shown in Figure 1.If swelling is to the angle shown in Fig. 1, support link is vertical with the axis of breathing draw bar 17, and the swelling of breathing arc plate is to upperlimit so.In the time that the internal diameter size of steel coil strip is greater than theoretical size, that breathing arc plate just cannot swelling steel coil strip or has been tied with the inner tube of a tyre paper web of steel band.So in fact breathing arc plate can not swelling arrive upperlimit, should keep one to be less than the angle of 90 ° with axis, like this in order to bear the weight of steel coil strip and innermost layer steel band or paper web to be maintained to enough friction force, support link and swelling connecting rod just produce an axial force to corresponding gusset, and be delivered to telescopic 13 and rotate on hollow shaft 27, make the two have respectively the relative trend expanding outwardly, therefore in the supporting structure that rotates hollow shaft 27 and in support and contracting mechanism, all should adopt thrust baring for this trend, this thrust baring can bear the axial force that this trend produces.Again because, when thrust baring in support and contracting mechanism also will bear breathing draw bar and outwards moves, the flexible bearing inner sleeve 22 of second imposes on its outside application force, therefore in support and contracting mechanism, the thrust shaft in telescopic 13 is promised and is adopted the two-direction thrust bearing that can bear bi-directional axial load, and the block bearing that rotates hollow shaft 27 adopts one direction thrust bearing.
The installation form of the present embodiment to above-mentioned two-direction thrust bearing 20 and the force transferring structure of breathing draw bar 17 are not limited to said structure form, can also between the flexible bearing inner sleeve of first and dish spring group, set up dish spring support ring, dish spring support ring can make the osculum of that dish spring that approaches the flexible bearing inner sleeve of first most towards the flexible bearing inner sleeve of first, if there is no dish spring support ring, that dish spring of the flexible bearing inner sleeve of so the most close first must be that large mouth is directly towards the flexible bearing inner sleeve of first, arranging of dish spring support ring increased the alerting ability that dish spring group is arranged.Same this dish spring support ring also can be arranged between dish spring group and second pillow block, has also improved the alerting ability that dish spring group is arranged near the dish spring at second pillow block place.
The present embodiment can also arrange disc spring sleeve beyond the external diameter of dish spring, and dish spring group 18 is contained in disc spring sleeve 15, and disc spring sleeve is bowl-type, and the bottom of bowl is sleeved on breathing draw bar, to retrain the radial runout of dish spring from external diameter.Maybe flexible second bearing inner sleeve can be extended, extend to the inner side of dish spring group, be equivalent to increase breathing draw bar diameter in this section, retrain the radial runout of dish spring from internal diameter.Except this function, increase disc spring sleeve and also improved the alerting ability that dish spring group is arranged, for example disc spring sleeve 15 is positioned at the inner side of two-direction thrust bearing 20 and opening in the time of two-direction thrust bearing 20, the spring of the inner side of dish spring group is just without the second pillow block 91 large mouth of single dish spring being against inside telescopic the inner, also can make the osculum of this dish spring towards four axistyle, the number of dish spring just no longer by large mouthful of the dish spring of outer end outwardly, the number that the large mouth of inner dish spring is constrained to dish spring has inwardly been necessary for odd number, also can be even number, can select flexibly according to the actual needs number and the kind of dish spring.Disc spring sleeve 15 is positioned at the tubular construction of roller bearing end cap 14, and does not contact with the tubular construction inwall of roller bearing end cap 14.
The length of above-mentioned disc spring sleeve 15 should guarantee in the time that dish spring group 18 does not stress completely, distance between the bottom inside of disc spring sleeve 15 and swelling bearing outer sleeve is greater than the amount of compression of dish spring, in order to avoid dish spring group 18 directly contacts with swelling bearing outer sleeve because of disc spring sleeve 15 in the time of compression, the problem that dish spring group 18 cannot continue compression occurs.
Refer to Fig. 1, the start cylinder 33 cylinder bars that drive breathing draw bar to move stretch out towards left side, the cylinder bar that is used for the start cylinder group that drives breathing draw bar 17 is provided with the push-and-pull action plate 46 vertical with them, and the outer middle side part of push-and-pull action plate 46 is provided with contiguous block 49, and contiguous block 49 is provided with T-shaped groove; The inner end of breathing draw bar is provided with the salient that radius is greater than its adjacent part, and salient is contained in T-shaped groove.The direction of T-shaped groove is 45 ° with the direction of the paired start cylinder cylinder bar line of centres.
Refer to Fig. 1, scatter in order to prevent the inside side of steel band in steel coil strip, on speed control sleeve 28, be provided with Internal baffle assembly 2, speed control sleeve 28 is packed in the outside of rotating hollow shaft 13, Internal baffle assembly is packed in the outside of speed control sleeve 28, speed control sleeve 28 outer ends are provided with the pillow block for locating Internal baffle assembly inner side, and the outside of Internal baffle assembly is held out against by Internal baffle steady ring 29, Internal baffle steady ring 29 by screw fastening on speed control sleeve 28.
Because steel coil strip is in the time being lifted on material volume expansion machine, can not 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 breathing arc plate is outside, axial direction is to the movement of machine intimate, the path of motion of steel coil strip is the same with the breathing arc plate of being propped up, can there is in the axial direction one-component, if directly the side of steel coil strip is against on the rectangular steel tube of Internal baffle assembly, between steel coil strip and breathing arc plate, can there is relative motion, and the friction force of relative motion is larger, the inner end edge of breathing arc plate is likely destroyed interior one deck or which floor steel band, cause whole steel coil strip to be subsided.So can not directly make of Internal baffle assembly the axial direction positioning device of steel belt for lifting volume.In the time that steel belt for lifting is rolled up, steel coil strip need to be placed on breathing arc plate, now just need on breathing arc plate, there is a registration device, to control steel coil strip in axial position.
Refer to Fig. 1, in the present embodiment, breathing arc plate inner reinforced plate 8 is provided with inner side registration device 37, and inner side registration device is arranged on breathing arc plate gusset one end near head shell.Inner side registration device comprises two connection boards that are arranged on breathing arc plate inner reinforced plate both sides, connection board is L shaped, horizontal bottom as with the connecting portion of breathing arc plate link of boards, vertical portion is as location division, the connecting portion of connection board is provided with horizontal slotted hole, in horizontal slotted hole, be provided with the fixing screw of connection board, fixing screw is fixed together connection board and breathing arc plate gusset.By the horizontal relative position of the control of parallel motion connection board itself and fixing screw, can adjust the relative position of inner side registration device and breathing arc plate, guarantee that steel coil strip is after completely by swelling, its inside edge can contact with the square tube of Internal baffle assembly, realizes the location of steel band.
Refer to Fig. 3, Fig. 4 a and Fig. 4 b, locate in like manner with inner side, the arranged outside of material volume expansion machine has outside registration device, and outside registration device is demountable structure.Outside registration device comprises steel band outer baffle and outer baffle registration device; Steel band outer baffle comprises outer ring 381, inner ring 383 and is connected the spoke 382 of outer ring and inner ring, and above part forms by metal tube.Outer baffle registration device comprises two pilot bars 392 and two abutment sleeves 385; Two abutment sleeve 385 disalignments, are all horizontally disposed with, and the length of one of them abutment sleeve is greater than another abutment sleeve, and two abutment sleeves 385 are respectively connected with the inner ring 383 of outer baffle by radius stay 384; Two pilot bars 392 are respectively fixed on the outer circumference surface that rotates hollow shaft 27 by 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 screw thread.By two point locations and a line location, can limit the axial location of outer baffle device, and can limit outer baffle swing like this.
Except taking above-mentioned setscrew nut the fastening device on its guide piece, also can adopt other fastening means as outer baffle, for example on abutment sleeve, be provided with an eccentric wheel hold-down mechanism, realize fastening function.Or the fastening abutment sleeve of jackscrew and outer baffle pilot bar are set on abutment sleeve.
The present embodiment, is fixed with brake disc 6 in the inner of speed control sleeve 28, and brake disc, perpendicular to the axis that rotates hollow shaft, is also provided with many disc brakes 5 on head shell, and brake disc is between two braking planes of disc brake.Damping arrangement can select disc brake that air pressure is less normally to move as material volume expansion machine time, makes to keep on discharged steel band a suitable tension force.Select one or more disc brakes that air pressure is larger as brake equipment.
The brake disc of mentioning, can also select damping and the brake equipment of cartridge type brake gear as material volume expansion machine in the present embodiment.
As shown in Figure 1, the principle of work of the present embodiment is:
One) before steel belt for lifting volume, the displacement cylinder group of respective side is released, displacement cylinder stretches out by the moving breathing draw bar of push-and-pull action strip, be packed in the flexible bearing inner sleeve of second on breathing draw bar by application force successively by the inner ring of two-direction thrust bearing, roller or ball, the outer ring of the outer end of two-direction thrust bearing is delivered on roller bearing end cap, promoting swelling bearing outer sleeve by roller bearing end cap 14 moves outward, and make to move outside telescopic 13 by circlip for bore 92, the outer gusset of telescopic being contained on telescopic also outwards moves thereupon together, angle between swelling connecting rod and axis reduces, angle between support link and axis reduces simultaneously, breathing arc plate is along outwards moving take the distance between support link and two hinge-points of swelling connecting rod as the circular arc of radius, the external diameter of the arc of breathing simultaneously plate also dwindles thereupon.In the time that the inner reinforced plate of breathing arc plate contacts with the outer gusset that rotates hollow shaft, the external diameter of breathing arc plate is retracted to minimum value, and now start cylinder still may not shrink and put in place.
Because the axial location of inner side registration device on breathing arc plate gusset can regulate, so before steel belt for lifting volume, need to adjust the position of determining inner side registration device.If directly steel coil strip is placed on breathing arc plate, the standard of neither one location, workman determines 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 excessively near apart from outer end, will cause breathing arc plate after swelling, the inner side of steel coil strip still cannot touch in the square tube of Internal baffle, steel coil strip does not have location, side, and the steel band keeping to the side most still likely subsides.If inner side registration device is excessively far away apart from outer end, although can utilize the square tube of Internal baffle accurately locates the side of steel coil strip, but can increase the distance of the friction of steel coil strip and breathing arc board mount, for there is no the steel coil strip of paper web, this,, by the steel strip surface of inner side in severe wear steel coil strip, gives; For the steel coil strip that has paper web as the inner tube of a tyre, although there is not the problem of wearing and tearing steel strip surface, also can strengthen the wearing and tearing to recycled paper web.And except wear problem, in the time that steel coil strip and breathing arc plate relatively move, friction force needs the application force of start cylinder to overcome, and certainly can increase the load of start cylinder, likely causes the increase of start cylinder size.Increased after the registration device of inner side, can be after once adjusting to the right place, it is carried out fastening, when each upper volume, just had one reproducible, the position reference of accurate positioning, without again adjusting, can avoid above-mentioned problem.
Two) steel coil strip is placed on breathing arc plate and after axial location, start cylinder shrinks, and the connector on start cylinder bar drives push-and-pull action plate, and then drives breathing draw bar to retract, the end first pillow block 95 of breathing draw bar end compresses dish spring group, and dish spring group is compressed.Because dish spring group is not little when amount of compression will be more than lifting steel coil strip in other words in compressive state in the time that breathing draw bar stretches out completely, so now start cylinder is only by breathing draw bar compact disc spring group, and do not cause that other change, for example, can suppose that now the amount of compression of dish spring group is 5mm.
When suffered compressive force in dish spring group reaches steel coil strip need to be risen to required application force time, telescopic is under the elastic force effect of dish spring, move to rotating in hollow shaft, and then by swelling connecting rod and support link, breathing arc plate is propped up, now the center of gravity of steel coil strip is constantly rising.
Angle when swelling connecting rod and support link are greater than these two connecting rods and have just started lifting steel coil strip with respect to the angle of axis while putting in place due to the swelling of breathing arc plate, so stressed (dish spring stressed) when swelling on connecting rod is less than the power while just starting lifting steel coil strip, the length of dish spring is greater than its length in the time just starting lifting steel coil strip, in the process of lifting steel coil strip, dish spring is in fact to discharge its amount of compression constantly, and now the amount of compression of dish spring group is 1.5mm.Now dish spring group still has certain compression surplus.So by after complete steel coil strip swelling, start cylinder still continues to release a segment distance at breathing arc plate, breathing draw bar continues to shrink inwards, swelling bearing outer sleeve compact disc spring group.Until reach start cylinder stroke, the lock of locking start cylinder interior is locked start cylinder, prevents that start cylinder from losing thrust because of gas leakage, the accident that causes material volume to fly out, and now the amount of compression of dish spring group is 3.5mm.At breathing arc plate, the length that after complete steel coil strip swelling, start cylinder bar continues to stretch out is to dish spring by the length of another compression, this amount of compression is 2mm.When the parts such as start cylinder, push-and-pull action plate, connector, breathing draw bar are installed more accurately, this length is needed just less, and the second-compressed amount of spring is also just less, and pressure when final material volume expansion machine operation in dish spring group is also just less.For above-mentioned reasons, when the operation of material volume expansion machine, in other words, the axial force after steel coil strip swelling is less, and after machine run gets up, the two-direction thrust bearing in outside and the thrust baring of inner side stressed also less, is conducive to improve the thrust baring life-span.
The generation of second-compressed amount is not only in order to make up the error while installing, and to have the effect that tension force is provided concurrently.Because in the process in fact constantly strutting at breathing arc plate, breathing arc plate is only also the gravity that equals material volume for the bearing capacity of material volume, now the elastic force on dish spring also with this bearing capacity to corresponding.If there is no second-compressed, that breathing arc plate will be the same (due to the geometric relationship between swelling connecting rod, breathing arc plate, support link and breathing draw bar with not using dish spring group to the tension force of material volume, can not produce larger tension force, otherwise will cause structural damage) use so the advantage of dish spring group to give prominence to.And the generation of this second-compressed amount, the positive corresponding generation of additional tension force, and this tension force can not disappear because of the gas leakage/leakage of start cylinder, and this additional tension force exactly, guarantee that breathing arc plate and material volume can have enough friction force between inner side (or material roll up paper web), control raising speed/reduction of speed that honest material convolution turns etc., improved the safety and reliability of system.For example, the weight of material volume is 1000 kilograms, when breathing arc plate will be expected the complete swelling of volume, application force in dish spring group is 800 kgfs, due to the second-compressed of dish spring group, application force in dish spring group has increased again by 320 kgfs, has increased again so the tension force of 400 kgfs between breathing arc plate and material volume inner side, and this has just increased the friction force between breathing arc plate and material volume inner side.
And technical scheme in employing the present embodiment, raising tension force that can be larger, and then the unwinding and rewinding machine that improves employing breathing arc plate form is rolled up the control ability of velocity variations to material, the acceleration/accel that can adapt to speed governing time, needs are larger and/or material are rolled up the larger occasion of rotor inertia, have expanded the range of use of such machine.
Three) after swelling has operated; outer baffle is contained on breathing arc plate; utilize two abutment sleeves and two pilot bars to realize the location to outer baffle; wherein two abutment sleeves have completed point location jointly; longer abutment sleeve has also completed the location that prevents swing; then use nut locking, can play the protective effect of the outer side edges to steel coil strip.
Complete behind the location, outside of steel coil strip, can start 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, can be referring to other compressibi1ity springs of mentioning in the 11st piece of spring chapter 1 spring of Chemical Industry Press's version " mechanical design handbook " the 3rd volume in 2002 of Cheng great Xian chief editor, for example resilient sleeve, cylindroid helical-coil compression spring etc.Nut 16 can replace by the limiting stopper of pin joint or by the locating dowel pin of breathing draw bar axis.

Refer to Fig. 6, and the difference of embodiment 1 is: between dish spring group and swelling bearing outer sleeve, also clamp and regulate grommet 60, regulate grommet 60 to be sleeved on telescopic inwall.Dish spring group 18 does not directly contact with the third pillow block 90 of swelling bearing outer sleeve 93, but contacts with the adjusting grommet 60 for size adjusting, regulates the external diameter of grommet 60 identical with the internal diameter of telescopic 13, and can slide axially between the inwall of telescopic.
In process of production, the internal diameter of steel band material volume can not be completely unified, and this patent depends on and pulls the locking start cylinder of breathing draw bar to move completely to put in place, utilizes lock in start cylinder to guarantee not occur the material volume accident that flies out.But the position that material volume internal diameter and breathing draw bar pull is to have certain relation of interdependence, if the internal diameter of material volume is larger than theoretical value, after causing driving the start cylinder cylinder bar of breathing draw bar to put in place, still cannot increase to position, also cannot guarantee even again discharge amount of compression by dish spring, so just need to adjust the relative position of dish spring support ring and breathing draw bar.For example, the position of swelling bearing outer sleeve is outwards moved, needing increases the thickness or the quantity that regulate grommet, makes start cylinder in the time moving to terminal, and the external diameter of breathing arc plate is less than original steel coil strip internal diameter; Vice versa.Regulate grommet can have various ways: 1) for 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 grommet, each regulates the internal diameter of corresponding a kind of material volume of thickness of grommet, in the time that the internal diameter of steel coil strip changes to some extent, increase or reduce corresponding adjusting grommet number; 2) while calculating respectively discharging volume internal diameter and be different size, required size regulates the size of grommet, makes respectively the adjusting grommet of coil diameter in corresponding each steel band, and in the time that the internal diameter of steel coil strip changes to some extent, integral replacing size regulates grommet.
Although by reference to the accompanying drawings the preferred embodiment of this patent is described above, but this patent is not limited to the above-mentioned specific embodiment, the above-mentioned specific embodiment is only schematic, be not restrictive, those of ordinary skill in the art is under the enlightenment of this patent, do not departing from the scope situation that this patent aim and claim protect, can also make a lot of forms, 1. replace the breathing arc plate inner reinforced plate described in this patent with hinged-support and rotate the outer gusset of hollow shaft, be arranged on respectively the inner side of breathing arc plate and the outside of rotation hollow shaft, and hinged with support link, play the effect of supporting breathing arc plate, 2. will change 3 or more number into for the cylinder number that struts each side breathing arc plate, the cylinder that supports both direction is still crisscross arranged.Within these all belong to the protection domain of this patent.
