A base material S1 for a ball which is processed into a long cylindrical shape and is formed so as to feed a core wire S2 made of an ultrafine single wire made of a shape memory alloy, and the long cylindrical base material for a ball It is a ball chain S for jewelry composed of a plurality of independent decoration balls 1 formed from S1, and the plurality of decoration balls 1 are at least two or more different types of decorations having different shapes and dimensions. A plurality of sets of ball balls 1a and 1b are arranged in order, and a plurality of sets of these two or more irregular decorative ball balls 1a and 1b are arranged as a set.

  Moreover, in the ball chain S for jewelry of Claim 2, the dotted | punctate weld part 2 is provided in the butt-like joint line part of the said base material S1 for balls formed in the elongate cylindrical shape. It is a thing.

  Therefore, according to the ball chain S for jewelry according to claim 1, it is possible to more easily and efficiently manufacture the ball chain S for jewelry having a beautiful shape with excellent decorativeness and good appearance. Further, the cost of the ball chain S for jewelry itself can be reduced, and it becomes more economical.

  In particular, the plurality of decorative ball single bodies 1 are constituted by at least two or more kinds of irregular decorative ball single bodies 1a and 1b having different shapes and dimensions, and the two or more kinds of decorative ball single bodies 1a and 1b are combined. As a set, a plurality of sets are arranged in a sequentially arranged state, so that it is possible to provide a ball chain S for jewelry having better decorativeness.

  Furthermore, since the core wire S2 is composed of an ultrafine single wire made of shape memory alloy, the overall shape of the ball chain S for jewelry is influenced by the shape stored in the core wire S2, and the appearance of the body A good ball chain S for clothing can be provided relatively easily.

  Moreover, in the ball chain S for jewelry of Claim 2, the dotted | punctate weld part 2 is provided in the butt-like joint line part of the said base material S1 for balls formed in the elongate cylindrical shape. As a result, the strength and durability of the decorative ball unit 1 itself can be increased, and even if there is an unexpected external force, the joint line portion of the decorative ball unit 1 is prevented from opening and can be easily cut. It is possible to easily and efficiently manufacture the ball chain S for jewelry that does not become a stale.

It is the schematic which illustrates the method of manufacturing this invention. It is a fragmentary sectional view which illustrates the ball chain for clothing of the present invention. It is a partially omitted front view illustrating a necklace using a ball chain for clothing of the present invention. It is the schematic which illustrates the other manufacturing method which manufactures this invention.

Hereinafter, the present invention will be described with reference to the drawings.
First, the base material S1 for the ball is made of, for example, an appropriate noble metal (for example, gold, silver, platinum, platinum, etc.) or an appropriate metal material plated with an appropriate noble metal, and has a thickness that is appropriate. A thin film of about 0.1 mm formed in the shape of an elongated strip is used.
The specific shape, dimensions, material, and the like of the ball base material S1 are not limited to those shown in the drawings, and can be set and changed as appropriate.

The core wire S2 is made of an ultrafine single wire made of a (superelastic) shape memory alloy such that, for example, an alloy such as titanium and nickel is used and the wire diameter is 0.2 to 0.4 mm. In other words, a straight line shape, a curved line shape, or any other arbitrary shape is stored in advance. That is, at a temperature higher than the transformation point (ordinary temperature or lower), one that is configured to recover to the original shape that is arbitrarily stored even if it is deformed is adopted.
By the way, the arbitrary shape may be stored in the core wire S2, after the ball chain S for clothing is formed, the arbitrary shape may be stored in the core wire S2 by an appropriate heat treatment.
Thus, when the ball chain S for jewelry having the core wire S2 is used as a necklace, the shape of the ball chain S for jewelry when the necklace is put on the neck is only affected by the gravitational force applied to the decorative ball alone 1. Without being formed, the shape memorized in the core wire S2 is taken into consideration, and the overall shape of the ball chain S for jewelry is more excellent in decorativeness. At least, it looks like a conventional necklace, and it is unlikely to hang from the neck as it is.
The specific shape, dimensions, material, and the like of the core wire S2 are not limited to those shown in the drawings, and can be set and changed as appropriate.

  The present invention can be manufactured, for example, by the following manufacturing process. That is, the first step is a step performed by the first processing unit having the cylindrical forming die A. For example, the ball base material S1 is introduced into the cylindrical forming die A along the longitudinal direction, and the ball In this step, the base material S1 is gradually squeezed in the width direction, and the left and right side edges thereof are smoothly and beautifully plastically deformed into a cylindrical shape with a butted shape. Moreover, it is a step of feeding the core wire S2 into the ball base material S1 formed in a cylindrical shape. That is, the ball base material S1 that has undergone the first process is formed in a cylindrical shape, and the core wire S2 that has undergone the first process is in a state of being accommodated in the cylindrical ball base material S1, and the cylindrical forming die. The second processed part is sent to the alligator A.

  The second step is a step performed by the second processing unit having the ball forming die B. For example, the ball base material S1 processed into a long cylindrical shape is made up of a plurality of independent decorative balls having a desired shape. 1 is a step of plastic deformation. That is, a pair of ball forming dies B are configured so that the processing concave surfaces B1 face each other and come close to each other, and balls processed into a long cylindrical shape by the processing concave surfaces B1 of the pair of ball forming dies B By sandwiching the base material S1 in stages, it is finally possible to form a plurality of separate and independent decorative ball elements 1 having a desired shape.

In addition, the plurality of decorative ball single bodies 1 formed in the second step are configured by at least two or more different types of decorative ball single bodies 1a and 1b having different shapes and dimensions. Moreover, the two or more types of irregularly shaped decorative ball single bodies 1a and 1b are set as a set, and a plurality of sets are sequentially arranged.
That is, the ball base material S1 in the second step is intermittently stopped for each length of a set of irregularly shaped decorative balls 1a, 1b. Then, the pair of ball forming dies B are separated and approached in connection with the intermittent stopping operation of the ball base material S1, and the ball base material S1 is intermittently sandwiched so that each pair of decorative balls 1 is stepwise. The deformed decorative ball single body 1a, 1b having a desired shape is formed by plastic deformation.

  Incidentally, the decorative ball single body 1a shown in FIGS. 2A and 2B is formed into a hollow sphere having an outer diameter of 0.7 to 1.2 mm, for example, and the decorative ball single body shown in FIG. 1b is formed into a hollow elliptical sphere having an outer diameter of 0.7 to 1.2 mm, and the decorative ball single body 1b shown in FIG. 2B is a hollow bowl having an outer diameter of 0.7 to 1.2 mm. Each of them is formed to be a single small decorative ball 1 that is considerably small. The specific shapes, dimensions, types, combinations, and the like of the decorative balls 1, 1 a, 1 b are not limited to those shown in the drawings, and can be set and changed as appropriate.

In addition, a laser welding apparatus C is disposed between the first processing part in the first step and the second processing part in the second step, and the ball base material is plastically deformed into a long cylindrical shape. The spot-like welded portion 2 provided by the laser welding apparatus C can be arranged at a desired position along the joint line at the butt-like joint line portion of S1.
That is, the welding part 2 should just be correctly comprised by the joint line part with the laser from the laser welding apparatus C. FIG. Moreover, the spot-like welded portion 2 may be, for example, one place for the single decorative ball 1, two places, or three places, so that sufficient strength and durability can be obtained. As long as the work efficiency is improved, the work efficiency may be improved.
