Fig. 1 and 2 shows the preferable embodiment of low pressure winding technique machine 10 of the present invention.Except the several important improvement of narrating below, coil winding machine 10 be one by the New Jersey, " BW " type loop coil coiling machine that Meccanica Generale S. R. L of A Wendun makes.It is to design on the basis of disclosed machine in above-mentioned Fahrbach patent.
In the course of work of coil winding machine 10, lead 25 from a lead in bulk source in a clockwise direction around in lead storage bin 18, as seeing among Fig. 2, until lead 25 in lead storage bin 18, contain predetermined length with after satisfying during the winding operation needs till.After this, the lead 25 that comes from lead in bulk source is cut off.The termination that maybe will be stored in the lead 25 in the lead storage bin 18 is fixed with hook or pin 64, and the latter is contained in an end of coil tire core 38, to provide coiling preceding top lead-in wire.As shown in Figure 3, by means of the rotation of shuttle plate 20, lead 25 takes out from lead storage bin 18, and by directive wheel 28a or 28b, around to coil tire core 38, adopts 28a or 28b to depend on the direction of rotation of shuttle plate 20.Hook 26 is used for mentioning the lead 25 in the storage groove 27 of lead storage bin 18, and guiding lead 25 is to directive wheel 28a or 28b.Because less than the diameter of lead storage bin 18, lead storage bin 18 can be independent of shuttle plate 20 and rotate effective coiling diameter of coil tire core 38 significantly, to adapt to owing to the different different speed that cause of coil diameter.
By means of rotate shuttle plate 20 and lead storage bin 18 lead 25 around to coil tire core 38 time, coil tire core 38 rotates around rotating shaft 40, and lead 25 is arranged in above the coil tire core 38 by the pattern of being scheduled to.
Figure 4 and 5 show lead once around the coiling pattern to coil tire core 38.Note, as shown in Figure 4, coil from tire core upper part begin around, and constantly carry out along with coil tire core 38 counterclockwise rotates around axle 40.When coil tire core 38 when axis 40 is done counterclockwise to rotate, shuttle plate 20 and lead storage bin 18 counterclockwise rotate (with respect to throwing apparent direction shown in Figure 2) around horizontal roll, lead 25 around to coil tire core 38.In above-mentioned winding process, coil tire core 38 is also finished some back and forth " shaking ", that is to say around axle 40 forward, to rotate backward under the control of controller 44, and lead is arranged by predetermined pattern, and Fig. 5 shows such example.Coil tire core 38 is that Fig. 4 view rotates to the counter clockwise direction shown in Fig. 5 view around axle 40 summations clockwise and that back and forth rotate counterclockwise.Since the rotation that coil tire core 38 continues causes the crepe cord coil structures, the reciprocally swinging of the recommendation of coil tire core 38 is more conducive to constitute non-helical shape coil.
Fig. 8 A-8E shows the coiling order of the multiply low pressure winding 48 of five leads, it should be noted that five strands of leads twine to make five strands of multi-thread coils in succession with sub-thread, and before the winding, core insulation tube 46 is enclosed within on the coil tire core 38, and this will describe in detail below.
In first burst of coiling, shown in Fig. 8 A, single cord 25 at first is fixed on the binding post 64, and at the end plate 114(of tire core 38 Figure 12) go up around a volume, with surplus that a lead is provided lead-in wire as coil windings top.Lead 25 is guided on the core insulation tube 46 then.First strand is that coiling is carried out in shuttle plate 20 rotation counterclockwise, and the horizontal solid line among Fig. 8 A represents that wire turn is that part of around coil tire core 38 tops, and the horizontal line dotted line is represented around the bottom of coil tire core 38 that part of.After finishing first burst of coiling, the residue length of lead is drawn to overhanging from coil tire core 38, is used as end leads on second binding post 66.For the wire turn that makes first burst of winding and differentiating of twining later on, the cross section of that part of lead is represented with half small circle of blacking in coil radially inner side and the outside.
Thereafter, back-roll in second burst of gap that is wound on the circle that winds the line (being the rotations of shuttle plate 20 clockwise directions) is shown in Fig. 8 (B), with distinguishing with a single horizontal line in horizontal solid line and horizontal dotted line and the small circle.After finishing second burst of coiling, the lead of one section residue length draws to overhanging from tire core 38, and the top lead-in wire of a winding is provided, and on first binding post 64.First strand and second burst of lead interlacing are wrapped on that one deck of being close to insulating core tube 46 with interweaving.
In Fig. 8 (c), show the 3rd burst of coiling with real horizontal line and empty horizontal line equally.In the 3rd strand of winding process, lead 25 counterclockwise rotates by means of shuttle plate 20 and carries out coiling.Represent with the small circle of band "+" word among the figure.During the 3rd burst of lead coiling, every turn-to-turn is reserved at interval almost evenly, wire turn is in the annular tire core outside, being close to core insulation tube 46 arranges, yet in annular tire in-core side, a part is around the ground floor of being close to core insulation tube 46, another part with approximately uniform ratio around the inside second layer in footpath.In other words, need the number of turn of twice half windings to form the radially inner side ground floor, after the 3rd strand of lead twined and finish, the residue length of lead 25 was drawn on second binding post 66 to overhanging equally, so that the end leads of coil to be provided.
The coiling of the 4th strand of lead has been shown among Fig. 8 (d), and shuttle plate 20 clockwise directions rotate.The real horizontal line in path of the 4th coiling of coil, empty horizontal line and in have the small circle of two parallel lines to represent.At annular tire core diameter laterally, wire turn is on the ground floor of being close to core insulation tube 46, and at annular tire core diameter to the inside, wire turn is on the second layer, and after coiling finished, the residue lead drew to overhanging, on the binding post 64 as the top lead-in wire of coil.
Fig. 8 (E) shows the coiling of last one lead, and it finishes the making of low pressure winding part.Wire turn counterclockwise rotates coiling by shuttle plate 20, every circle be filled in around the remaining gap of several strands of leads in, the path of the 5th burst of lead coiling is represented with the small circle of real horizontal line, empty horizontal line and blacking.Available space of radial outside ground floor and radially inner side second layer space have been filled up in the coiling of last one lead basically.After finishing the 5th burst of lead coiling, end leads is drawn around to binding post 66 to overhanging, and after this, all lead-in wires of guiding on the binding post 64 twist together, and all lead-in wires of guiding on the binding post 66 twist together, to form the multiply coil.
As a kind of replacement of five strands of lead winding methods shown in Fig. 8 (A)-8(E),, can finish coiling with the step of lacking than the stranded conductor coiling by once twining stranded conductor.When first time coiling, rotate with a direction around bobbin by means of shuttle plate 20, coil tire core rotates toward the mode of shaking by multiple around axle 40 simultaneously, two or multiple conducting wires are around to tire core 38, each circle radially inner side surface at tire core 38 arranged side by side of two or multiple conducting wires, along the circumferential direction go up on radial outside surface at tire core 38, separates mutually between two adjacent turn.When second time coiling, rotate with another direction around its coiling axis by means of shuttle plate 20, coil tire core 38 is done rightabout multiple toward shaking around axle 40, and two or multiple conducting wires are on tire core 38.Two or each circle of multiple conducting wires of coiling for the second time, on coil tire core 38 radially inner side surfaces, lap wound on the radial outside surface of coil tire core 38, is arranged between adjacent two circles of coiling for the first time on the wire turn of the coiling first time.
The wire turn of low pressure winding 48 is preferably without spirality.Or rather, wire turn has the line segment of axial location at the coil radially inner side and the outside that part of (with respect to axle 40), and coil all has radially usually in top and bottom or non-radially transition.Wire turn radially inner side and outer felt around determining positions in the pattern of the coil shown in Fig. 8 (A)-8(E).Wire turn across that part of determining positions in top and bottom in the position that is connected inner surface and outer surface.This location is determined by shaking the course of work, shown in Fig. 6,7A and 7B.
Do not need to understand the process of shaking, could fully understand the present invention, this process changes with designer's requirement.In fact, in order to make the non-helical shape coiling of lead, coil tire core 38 shakes with counter clockwise direction clockwise around axle 40, shown in Fig. 7 A and 7B.In order to make lead 25 across a certain part of coil location, after lead has touched a rib of coil tire core to lead become to touch coil tire core 38 another ribs before, be seamed edge 39A and 39B, corresponding to shaking process D, coil tire core 38 rotates to shake process A-D clockwise or counterclockwise around axle 40, so that lead 25 is throwed along non-helical direction, shown in Fig. 7 A.Along with shuttle plate 20 continues counterclockwise to rotate around its axle, lead 25 touches the seamed edge 39B of coil tire core 38 outer side-lowers, has determined the position across the lead 25 of coil tire core lower surface.This makes and shakes process D end.Along with shuttle plate 20 coiling tire cores 38 rotate, the process of shaking clockwise or counterclockwise continues, so that lead 25, so provides the inboard and the outside wire turn of axial orientation around to tire core 38, and the pattern of pressing Fig. 8 A-8E, connect top and bottom wire turn.In general, the determining positions that lead 25 is walked around every seamed edge on the coil tire core 38 in the front around that seamed edge of tire core 38 with respect to the position of the directive wheel 28 of shuttle plate 20, lead 25 in front around the seamed edge of tire core 38 and directive wheel 28 between form straight line.Rotation along with shuttle plate 20, lead 25 along the front around seamed edge and the straight line between the directive wheel 28 a bit contact in the centre with adjacent seamed edge on the tire core 38, therefore between two seamed edges, determined the position of lead 25, the purpose of shaking process each time is a rotating coil tire core 38, and lead 25 is correctly located on tire core 38 each bar seamed edge.Fig. 8 A-8E shows by the coiling order and determines the position of wire turn on seamed edge.
With reference to Fig. 9 and 10, can see in the process of coiling low-voltage coil 48, a core insulation tube 46 that is pressed into paperboard form has been installed on coil tire core 38.Low-voltage coil 48 comprises that an internal layer wire turn part 50 and an outer wire turn part 52(latter are only shown in Figure 10), the two separates by an insulating barrier 54.The shape of core insulation tube 46 is just in time encircled the coiling magnetive cord that is wrapping transformer, so its cross section is curved, and it and second such insulating cylinder can be arranged by same axis, forms one section about 330 ° toroidal cores tube.Each end of core insulation tube 46 all has a pair of end block 56 and 58, and end block 58 is installed on the radial outside surface of core insulation tube 46, and end block 56 is installed on the radially inner side surface of core insulation tube 46.As shown in figure 11, radial outside end block 58 has skewed slot 59 and 61, with lead-in wire 62 location of the lead-in wire 60 of internal layer wire turn 50 and outer coil 52 and pack into.The start lead 60 of internal layer wire turn 50 is stretched out from the top 38A of coil tire core 38, and fixing by the slot upper 61 of end block 58.The end leads 60 of internal layer wire turn 50 is stretched out from the terminal 38B of coil tire core 38, and is fixed in the slot lower 59 of end block 58.Equally, the lead-in wire 62 of outer wire turn 52, when coiling began and finish, also the remainder in slit 59 and 61 was fixed respectively.Arrange the position of low-voltage coil lead-in wire as stated above, but the semiorbicular coil of an interchangeable direction of coiled, wherein the lead-in wire of coil is drawn from same relevant position, no matter and the installation site of coil in transformer integral body how, can both keep correct direction of winding.
With reference to Fig. 9, wherein show the coiling result of the interior layer segment 50 of stranded conductor low-voltage coil 48.Layer segment 50 has an independent layer conductor in it should be noted that on the radial outside surface of annular insulating cylinder, on the radially inner side surface of ring-type insulating cylinder two layer conductors is arranged.In addition, can see the insulation interlayer of being made by insulating material 54 in Fig. 9, this layer should adopt the wrinkle paper tape, wraps the internal layer wire turn 50 of low-voltage coil 48.It should be noted that wrinkle paper tape its adjacent when swathing is actually overlapping in order to be surrounded by one deck crepe paper at least on the radial outside surface of internal layer wire turn 50.After swathing insulating barrier 54 internal layer wire turn 50 covered, the outer low pressure wire turn 52 of coiling again, as shown in figure 10.It should be noted that the mode coiling that outer layer segment 52 usefulness and internal layer wire turn 50 are same, on ring-type insulating cylinder radial outside surface around the individual layer lead, and on ring-type insulating cylinder radially inner side surface around dual-layer metal line.In the winding process of low-voltage coil 48 or after finishing, should use adhesive lead wire turn on the throne, can use B level heat to coagulate the lead coating, by dry processing while winding the line, be dried to and can touch; Another way is that the heat of using hygrometric state in the coiling process is coagulated adhesive.
Referring now to Figure 12, wherein show coil tire core 38 with the perspective view that decomposes.Coil tire core 38 comprises upper and lower arc supporting disk 70 and 72, and they are linked by three lateral struts that can stretch 74,76 and 78.Each lateral struts 74,76 and 78 all comprises an extendible seam 80, and for example, this seam 80 can comprise a pair of taper pad 82 and 84, and this pad is on the pressure bolt 86, and bolt 86 is screwed into and passes pressure plare 88, as shown in figure 14.The assembling of pressure plare can make it move along guide blot 89.Taper pad 82 and 84 inner surface are pressed in respectively on the taper convex surface 90 and 92 on the upper and lower strutting piece 94 and 96 of lateral struts.Rotation pressure bolt 86 just makes taper pad 82 and 84 1 startings, its effect make support component 94 and 96 trends away from, therefore just with the arc supporting disk 70 and the 72 distance increasings of upper and lower.An opening 97(Figure 12 is arranged on lateral struts 74) so that make instrument 99 can enter into the end of pressure bolt 86.Instrument 99 is meshed with the termination of each pressure bolt 86 of three telescopic intermediate studdles 7476 and 78, removes rotating bolt 86, tire core 38 is strutted or tightens.
By tire core 38 is strutted, can force the madial wall and the wall angular position of the upper and lower of upper and lower arc supporting disk 70 and 72 compacted iron core insulation tubes 46, for coil tire core 38, core insulation tube 46 is supported securely, and prevent that also the core insulation tube subsides and is out of shape in the process of coiling low-voltage coil 48.For this point, if support insecurely, to tighten under the coiling situation, coiling low-voltage coil 48 will cause core insulation tube embossed paper plate structure to subside or be out of shape before the fixedly processing that then will carry out.Certainly, if make the insulating cylinder structure more solid, can avoid this distortion with higher cost.Yet telescopic tire core 38 also provides a kind of easy means for dismounting core insulation tube 46 in the coiled process in provide the structural support.In addition, by inwardly dwindling the distance of supporting disk 70 and 72, after coiling finished, low-voltage coil 48 can be taken off from coil tire core 38 easily.
End plate 98 and 100 is fastened to the end of telescopic coil tire core 38, with the fixed-site of insulating cylinder 46 on coil tire core 38.End plate 100 is fixed on lateral struts 78, and is provided with an aperture 104, so that make instrument 99 can enter into the end of pressure bolt 86, as shown in figure 12.End plate 100 also has an assembling plug 106, and this assembling plug 106 rigidly fixes with lateral struts 78 with buck plate 100 and is connected, and its profile can mesh securely with the chuck 32 and 34 of tire core clamp 30.For this purpose, chuck 32 and 34 has short column 108, and assembling plug 106 then has corresponding grooves 110.
The assembling that end plate 98 and lateral struts are 74 is demountable, so that pack into and take out core insulation tube 46.End plate 98 has an aperture 112, so that make instrument 99 can enter into the end of bolt 86, is used for strutting and tightens lateral struts 74.End plate 98 also has an assembling plug 114, and generally speaking, assembling plug 114 can be taken off with end plate 98.The fixture 116 of band screw thread is used for realizing assembling removably connecting between plug 114 and end plate 98 and the pillar 74.As shown in figure 13, when removing the fixture 116 of band screw thread, end plate 98 and taking off together with the assembling plug 114 of wrapping post can install to insulating cylinder 46 on the coil tire core 38 whereby, and after coiling finishes, it can be taken off equally.Assembling plug 114 has coiling hook 64, and assembling plug 106 has coiling hook 66.
Another kind of coil tire core 120 has been shown among Figure 15.Coil tire core 120 is different from coil tire core 38 parts and is: it is to be assembled on the axle pivot on the assembling plug 122 with pivot 124, therefore that a part of coil tire core 120 with core insulation tube 46 can rotate with respect to assembling plug 122, makes before coiling low-voltage coil 48 and is easy to afterwards and pack into and take out core insulation tube 46.Because core insulation tube 46 must take off till breaking away from coil tire core 38 fully from coil tire core 38 in circular motion, so pivot 124 just is convenient to take out core insulation tube 46 especially.Because core insulation tube 46 has certain-length, when not providing the gap of packing into and taking off up to being close to assembling plug 106, it could throw off coil tire core 38.Hinge joint has the tire core 120 of core insulation tube 46 because permission is in the outside, so adopt pivotally connected assembling plug 122 to increase significantly in order to take out the gap of core insulation tube 46.
In Figure 16,17 and 18, illustrated according to second low-voltage coil coiling machine 130 of the present invention.The coiling machine 130 of this low-voltage coil is suitable for winding multi-strand lead low-voltage coil one time.Once twine for ease of multi cord, from a stranded conductor source or from a plurality of single cords source with each burst of stranded conductor while around storage line case 134.Clockwise after in storage line case 134, shuttle plate 136 and storage line case 134 promptly rotate counterclockwise with each strand of lead 132, with stranded conductor 132 on core insulation tube 46, shown in Figure 19 A-19E.When shuttle plate 136 rotated counterclockwise, stranded conductor 132 just was raised, and unclamped from storage line case 134 by means of stranded conductor hook 138.For ease of realizing this purpose, stranded conductor hook 138 has a plurality of direction recess, and each dividend of stranded conductor 132 is with a groove.
In order counterclockwise to carry out the once winding of multiply coil, adopted the directive wheel 152a of a band groove, each strand of stranded conductor 132 utilizes this groove.After directive wheel 152a, along with rotating counterclockwise of shuttle plate 136 and storage line case 134, stranded conductor 132 is just around to core insulation tube 46.An adjacent directive wheel 152b also has groove, and each strand of stranded conductor 132 utilizes this groove, and this directive wheel 152b twines in order to make clockwise direction.
