Embodiment
Figure 1A and B are the figure of first execution mode of illustration winding jig involved in the present invention, and Figure 1A is a vertical view, and Figure 1B is the cutaway view at the A-A line place of Figure 1A.
The size of winding jig 1 according to the size of required dihedral coil etc., is suitably selected to get final product.Particularly, protuberance 14,14 ... The length of long side direction, cooperate the diameter dimension of the dihedral coil of making suitably to regulate and get final product.And, protuberance 14,14 ... The length of long side direction, need not all identical.
Be preferably the distance X between opposed of first flange part 12 and second flange part 13
1, and protuberance 14,14 ... Height X
2, suitably regulate according to the kind of the kind of the lead of reeling, diameter dimension and required dihedral coil.In the present invention, the precision of the dihedral of dihedral coil depends on protuberance 14,14 ... And the distance (X between opposed of second flange part 13
1-X
2).
For example, use following that kind many metal fine boundlings are formed as lead, with this lead radially overlapping coiled one row of spool 15 and make under the occasion of the multilaminate coiled coil of a so-called row, be preferably above-mentioned distance X
1Be 1.5～1.9 times of diameter dimension of lead.On the other hand, be preferably above-mentioned distance (X
1-X
2) be 1.0～1.5 times of diameter dimension of lead.
Material to winding jig 1 does not have special qualification, suitably selects to get final product according to purpose.For example, can use metal, plastics etc., also can various material be made up and use.And winding jig 1 utilizes known gimmick to be shaped or assembling gets final product.
Fig. 2 A to C is that explanation uses winding jig 1 to make the figure of the operation of the multilaminate coiled dihedral coil 10 of a row; Fig. 2 A is the vertical view that lead 6 is wound on the state of winding jig 1; Fig. 2 B is the amplification view at the B-B line place of Fig. 2 A, and Fig. 2 C is the amplification view at the C-C line place of Fig. 2 A.In addition, in Fig. 2,, and omit its detailed description to the identical inscape mark prosign of representing with Fig. 1 of inscape.This figure to the back is suitable for too.
Shown in Fig. 2 A, through with lead 6 being initial point on the periphery of spool 15, in the zone that first flange part 12 and second flange part 13 are seized on both sides by the arms, and spool 15 radially carry out overlapping coiling, form the multilaminate coiled dihedral coil of a row.
At this moment, in the zone of being equipped with protuberance 14, shown in Fig. 2 B, the distance (X between the protuberance 14 and second flange part 13
1-X
2), when roughly the same, lead 6 is being held under the arm with protuberance 14 by second flange part 13, shown in Fig. 2 B, is wound as a row with the diameter dimension of lead 6.
Relative therewith, in zone, shown in Fig. 2 C, because the distance X between first flange part 12 and second flange part 13 away from protuberance 14
1Greater than the diameter dimension of lead 6, therefore become spiral shape such shown in Fig. 2 C.

In addition, in Figure 1A and Fig. 2 A, represented cylindricly as spool 15, but the shape of spool not only is confined to this, so long as the spool of tubular gets final product.For example, the shape in the diametric(al) cross section of spool, that is, no matter the shape of the spool of coil is any shapes such as circle, ellipse, polygon, the profile of the dihedral coil of being made does not receive the influence of these shapes of spool basically.
In addition, in Figure 1A and Fig. 2 A, represented that as protuberance 14 angle is bar-shaped, but the shape of protuberance not only is confined to this, so long as convex gets final product.
In addition, be preferably, second flange part 13 removably be fixed in the end of spool 15.Thus, can be easily pull down the dihedral coil after the manufacturing from anchor clamps.Method to second flange part 13 removably being fixed in the end of spool 15 is not done special qualification, can utilize known method yet, for example, the end of spool 15 is embedded in this locational recess that is arranged on second flange part 13.
In addition, in Figure 1A and Fig. 2 A, represented discoid parts, but these flange parts are so long as have can with the parts Any shape on the prominent plane of establishing of protuberance as first flange part, second flange part.
Like this, if use winding jig of the present invention,, can make the dihedral coil of different shape through number and the configuration pattern that changes the protuberance that is arranged at flange part radially.Particularly, the number of vertex of dihedral coil, with identical by the number of the protuberance that is provided with radially, the distance between each summit is decided by the formed angle of adjacent protuberance.Therefore, be arranged at number and the adjacent formed angle of protuberance of the protuberance of flange part, suitably select to get final product according to purpose.
