Hereinafter, with reference to the accompanying drawings will be described in detail for the accessory chain and its manufacturing method according to the present invention. The following embodiments are merely illustrative of the present invention and are not intended to limit the scope of the present invention.

1 to 4 are process drawings showing an exemplary method of manufacturing a chain for accessories according to the present invention, and FIG. 5 is a schematic diagram of exemplary coil spring-type wires that can be used in the method for manufacturing an accessory chain of the present invention. Fig. 7 is a schematic cross-sectional view of an exemplary accessory chain according to the present invention, and Fig. 8 is a schematic view of an exemplary accessory chain according to the present invention. It is a state of use.

First, the manufacturing method of the chain for accessories according to the present invention will be described step by step.

The first process of the accessory chain manufacturing method according to the present invention is a process of joining two or more coil spring wires 10 side by side so that the spirals 11 overlap each other (see FIG. 1).

Coil spring-type wire 10 that can be used in the present invention means a wire wound spirally, such as coil spring, coil spring-type wire 10 is a metal (eg, copper) easy to process widely used in the processing of accessories , Copper alloy, gold, silver, and the like).

As shown in FIG. 1, the coil spring wire 10 is particularly limited as long as the coil spring wire 10 can overlap each other's spirals 11 while being arranged side by side with another adjacent coil spring wire 10. Not.

That is, as the coil spring wire 10 according to the present invention, the coil spring wire 10B having the circular spiral 11A shown in FIG. 5 or the coil spring wire 10B having the rectangular spiral 11B is shown. Of course, any shape of the coil spring type wire 10 to which the manufacturing method of the present invention may be applied may be used.

1 to 4 show an example of manufacturing the chain 1 of the present invention using four coiled spring wires 10 of the same formation with circular spirals 11. The number of coil spring wires 10, the shape and the diameter of the helix can be appropriately selected and used according to the intended use of the chain 1.

The chains 1 illustrated in FIG. 7 are made of coil spring wire 10, two (A), three (B, C), four (D, E), and eight (F). Only a few of the chains (1) produced using each one is illustrated. In FIG. 7C, the coil spring wire 10B having the rectangular spiral 11B as shown in FIG. 5 is disposed at the center, and the coil spring wire 10A having the circular spiral 11A as shown in FIG. It illustrates the chain 1 manufactured by arrange | positioning on both sides, respectively.

In FIGS. 1 to 4, when the four coil spring wires 10 are overlapped with each other, the chain 1 is disposed so that the rotation direction of the spiral 11 is opposite to the adjacent coil spring wires 10 adjacent to each other. Although the example which manufactures this is shown, the rotation direction of the spiral 11 can also be arrange | positioned in the same direction.

For example, as shown in Figs. 1 to 4, when the spiral rotation directions are alternately arranged, the chain 1 has a shape as shown in Figs. 4, 7A and 7D, but the spiral rotation directions are the same direction. In this case, the chain 1 is shaped like B in FIG.

As described above, according to the present invention, the shape of the finally produced chain is changed according to the arrangement relationship of the rotational direction of the spiral 11 of the coil spring wire 10 arranged to face each other.

A second step of the method according to the present invention is a step of mutually binding the coil spring wires 10 arranged to overlap each other by the first step with the binding wire 20 (see FIG. 2A). .

In the first process, the coil spring wires 10 which are opposed to each other do not twist the spiral 11 and the spiral 11 with each other, but as shown in FIGS. 1 and 6, one coil spring wires are shown. Since the spiral 11 of the other coil spring type wires 10 is simply inserted and overlapped between the spiral 11 of the 10 and the spiral 11, the coil spring type wires 10 are disposed from the side. Pull it back out.

Therefore, in the second process, the coil spring wire is inserted by inserting the binding wires 20 through the spiral 11 of the two adjacent coil spring wires 10 and the overlapping portion 12 of the spiral 11. The fields 10 are not separated from each other.

As the binding wire 20, it is preferable to use a wire made of a rigid metal (eg, a steel straight wire) so that the coil spring wires 10 can maintain their arrangement without being deformed. It is preferable to use the bundle wire 20 with a small diameter within the range which maintains the strength so that the binding wire 20 may not be exposed to the line of sight in the final chain 1 without affecting the shape formation of the chain 1.

In the binding wire insertion step, the binding wires 20 are inserted into the overlapping portions 12 of the spirals 11, and the non-overlapping portions of the spirals 11 (hereinafter, referred to as 'non-overlapping portions'): The molded wire 30 or the decorative wire 40 can be inserted into all or part of the () (see Fig. 2 B and 6).

The forming wire 30 serves to deform the rolled shape of the coil spring wire 10 by acting as a mold when the coil spring wire 10 is rolled in a subsequent rolling process. That is, when the coil spring wire 10 is rolled in the state in which the shaping wire 30 is inserted, the rolling of the coil spring wire 10 is affected by the presence of the shaping wire 30, resulting in the final chain. The shape of (1) is to vary depending on the presence or absence of the molding wire (30). The main wire 30 is removed from the coil spring wire 10 after the coil spring wire 10 is rolled to a required degree.

The decorative wire 40 also acts to slightly deform the rolled shape of the coil spring-type wire 10 like the forming wire 30, but the difference from the forming wire 30 from the final chain (1) It is not removed but remains inserted and thus itself serves a decorative function. 7E shows an example of a chain 1 manufactured by inserting four decorative wires 40 into four coil spring-type wires 10, respectively.

In view of the action of the forming wire 30 and the decorative wire 40 as described above, as shown in Figure 2 and 7 E, the wire is relatively larger in diameter than the binding wire (20) Is used.

The third step of the present invention is a step of preliminarily rolling the tip 10E to hold the rolling direction before rolling the bound coil spring wires 10 in full scale (see Fig. 3).

In this pre-setting process, the pressing direction of the spiral 11 is set in advance before rolling the coil spring wire 10 in earnest, so that the coil spring wire 10 is not intended in a subsequent rolling process. Since it is prevented from rolling in the shape or shape, the failure rate in the rolling process can be lowered.

Accordingly, in the chain 1 having a structure in which uniform rolling can be made without presetting in the pressing direction, the fourth step may be performed immediately without the present presetting step.

The pre-setting process can be performed, for example, by pressing the tip 10E of the coil spring wire 10 with a press device 2 having a mold formed to match the pressing direction of the desired coil spring wire 10. .

The shape of the final chain is changed by adjusting the degree of overlap of the coil spring wires 10 before the pre-setting process. For example, when the degree of overlap of the adjacent coil spring wires 10 is increased, the spirals are densely arranged as in the inner part of the chain 1 shown in FIG. 7F, and the degree of overlap is reduced. As shown in FIG. 7, the spirals 11 are loosely arranged as in the chain 1 of FIG.

By inserting the binding wire 20 in the non-overlapping portion 13 in addition to the overlapping portion 12 so that the degree of overlap of the coil spring-type wires 10 adjusted as necessary is maintained intact in the rolling process, You can also prevent the nesting from changing.

In the fourth process of the present invention, the entire coil spring wire 10 is rolled flat as necessary in the pressing direction preset in the third process to finally complete the chain 1 (see Fig. 4). . This rolling step can be performed by the roller type rolling apparatus 3, for example.

The shape of the roller 4 of the rolling apparatus 3 can be suitably selected according to the shape of the chain 1 to manufacture. For example, when manufacturing a chain which does not need to control the widening sideways by rolling, a flat roller 4A having a flat roller surface can be used, and the width of the chain 1 must be limited to a constant width. If there is, the uneven roller 4B having unevenness corresponding to the width of the chain on the roller surface can be used.

When the latter uneven roller 4B is used, when the coil spring wire 10 is inserted into the groove and rolled, the coil spring wire 10 is rolled only up to the width corresponding to the width of the groove, so that the width is uniform. I can keep it.

Although this rolling process can be performed by only one rolling, it is preferable at the point that rolling in steps, narrowing the space | interval of the roller 4 little by little over several times, can lower the defective rate of the chain 1.

As described above, the binding wire 20 is used to bind the coil spring-type wires 10 to each other. Since the diameter of the binding wire 20 is small, the binding wire 20 has little effect on the shape or design of the chain even though it is maintained in the final chain 1. In some cases, it may be desirable to remove it.

The binding wire 20 can be removed in the middle of the present rolling process. That is, in the state where the coil spring wires 10 are only slightly rolled in the rolling process, since adjacent coil spring wires 10 are in a state of being bited together, even if the binding wire 20 does not exist thereafter. Since it is possible to maintain the mutually bound state and the coil spring type wires 10 are not completely compressed, the binding wire 20 can be removed. The binding wire 20 can be removed by pulling it out, after which the chain 1 is free of the binding wire 20 in which the rolling process is completed.

The chain 1 of the present invention manufactured as described above is finished in a chain for accessories by cutting to a length suitable for the intended use after finishing processing to be suitable for use as accessories.

According to the series of processes according to the invention described above, there is provided a chain 1 characterized in that two or more coil spring type wires 10 are rolled flat against each other such that the spirals 11 overlap each other. .

The chain 1 of the present invention thus manufactured includes a bracelet 5 as shown in FIG. 8 according to its size and shape, and a variety of accessories such as anklets, necklace straps, watch straps, shoulder straps for handbags, belts, and the like. It can be used as. In Fig. 8, reference numeral 6 denotes a hook of the bracelet 5.

In addition, when the decorative wire 40 is inserted into the non-overlapping portion 13 and rolled, the chain 1 having a shape in which the decorative wire 40 is inserted into the coil spring wires 10 as shown in FIG. ) Is formed.

According to the present invention described above, it is possible to provide a chain (1) for accessories of various shapes in which the coil spring-shaped wires (10) are superimposed and bound by the binding wire (20) and rolled. The chain 1 is expected to be widely used as a string material for various accessories such as bracelets, anklets, necklace straps, watch straps, shoulder straps for handbags, belts, and the like.
