JP2000312608A - Production of ornamental parts made of noble metals - Google Patents

Abstract

PROBLEM TO BE SOLVED: To prevent the burn of, for example, silicone resins and rubber which are the non-refractories near weld zones by irradiating the joint parts to accessory parts constituted by having non-refractories with a laser, thereby welding the joint parts. SOLUTION: The process for producing the ornamental parts made of noble metals is constituted by having the non-refractories. The joint parts 1c of portions of the accessory parts 1 formed by putting, for example, silicone resins and rubber, etc., 1b which are the non-refractories into, for example, hollow shells 1a made of the noble metals and another parts made of the noble metals, for example, annular bodies 2 are welded by irradiation with a laser beam from a laser emission device. As a result, the welding is executed by rapidly heating only the portions irradiated with the laser. Since the irradiated parts cool rapidly and naturally when the irradiation with the laser is ended and, therefore, the silicone resins, rubber, etc., which are the non-refractories near the weld zones are no longer burned as much heat conduction is not given to the parts exclusive of the weld zones.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of manufacturing a noble metal decorative part such as a noble metal accessory part to be attached to a noble metal decorative chain such as gold, silver or platinum.

[0002]

2. Description of the Related Art Generally, a precious metal part is joined to an accessory made of a precious metal such as gold, silver or platinum, for example, an accessory such as a brooch or an accessory part made of a precious metal attached to a precious metal decorative chain. In this case, a brazed joint is used in which the joint is heated by a gas burner or the like and a brazing material is melted into the joint.

[0003]

However, an accessory part in which a non-refractory material such as silicone resin or rubber is put in a noble metal hollow shell attached to a noble metal decorative chain, for example. If other precious metal parts are to be attached to the part by brazing, the heat of the brazing will burn out the non-refractory, so brazing was considered impossible and limited to the manufacture of accessories. Had occurred. This invention, when joining a precious metal accessory part partially having a non-refractory and another precious metal part, or when joining precious metal accessory parts partially having a non-refractory, Or joining precious metal accessory parts with other precious metal parts, near non-refractory materials,
Alternatively, there is provided a method of manufacturing a noble metal decorative part in which, when joining accessory parts, the joint is irradiated with a laser and only the joint is rapidly heated to perform welding. It is intended.

[0004]

In order to achieve the above object, the invention according to claim 1 is directed to a joint between a noble metal accessory part having a non-refractory and another noble metal part. A method for producing a noble metal decorative part, characterized in that the part is welded by laser irradiation.

According to a second aspect of the present invention, there is provided a decoration for precious metal decoration, wherein a laser beam is applied to a joint between two noble metal accessory parts having a non-refractory material. It is a method of manufacturing a part.

According to a third aspect of the present invention, a laser is applied to a joint between a noble metal accessory part and another noble metal part or a joint between accessory parts near a non-refractory. And a method for manufacturing a noble metal decorative part characterized by being welded.

[0007] As described above, by irradiating the noble metal joint with the laser and welding the noble metals to each other, only the portion irradiated with the laser is rapidly heated and the welding is performed. Even if there is a non-refractory material such as silicon resin or rubber, the non-refractory material will not be burned.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a method for manufacturing a metal decorative part according to the present invention will be described below with reference to the drawings. Claim 1
As shown in FIG. 1, the invention according to the present invention is configured to include a non-refractory material. For example, a non-refractory material such as a silicone resin or rubber 1b is put in a hollow shell 1a made of a noble metal. A laser is emitted from a laser emitting device (not shown) to a joint 1c between a part of the accessory part 1 and another part made of noble metal, for example, the ring body 2, and is welded. This is a method of manufacturing a noble metal decorative part.

According to a second aspect of the present invention, there is provided a decoration for a noble metal decoration, wherein a laser beam is applied to a joint between two noble metal accessory parts having a non-refractory material. It is a method of manufacturing a part.

According to a third aspect of the present invention, a laser is applied to a joint between a noble metal accessory part and another noble metal part or a joint between accessory parts near a non-refractory. And a method for manufacturing a noble metal decorative part characterized by being welded.

According to the present invention, as described above, a part of a noble metal accessory part having a non-refractory is joined to another noble metal part, and a noble metal accessory part having a non-refractory is connected to each other. When joining or joining precious metals in the vicinity of non-refractory materials, laser welding is applied to the joints, so-called laser welding, so that only the laser-irradiated parts are rapidly heated. When the laser irradiation is completed, it cools naturally immediately, so that it does not provide much heat conduction to the parts other than the welded parts, so that non-refractory materials such as silicon resin and rubber near the welded parts are removed. Burnout will not occur.

In this laser welding, a laser beam is applied to the center of a welded portion in an amount necessary for welding.
In order to increase the strength of the welded portion, it is also possible to add a necessary amount of material of the same quality as that of the joined material to the joined portion and to weld the same at the same time. By employing such laser welding, a wide range of designs can be applied to accessory products.

Reference numeral 3 shown in FIG. 1 is a decorative chain made of a noble metal such as gold, silver or platinum, and this decorative chain 3 is a non-refractory material in a hollow shell 1a made of a noble metal. For example, the accessory part 1 is inserted into a through hole 1d formed in the accessory part 1 in which a silicone resin, rubber 1b, or the like is inserted, and the accessory part 1 is attached to the decorative chain 3. When you move along, the decoration chain 3
The accessory part 1 can be held at the moving position by friction between the accessory part 1 and, for example, a silicone resin or rubber 1b.

At one end of the decorative chain 3, a noble metal decorative metal fitting 5 is attached via a noble metal ring 4. A noble metal hook 6 is attached to a noble metal ring 2 laser-welded to a part of the accessory part 1 as described above via a noble metal ring 4 ′. A noble metal plate 7 attached to the other end of the noble metal decorative chain 3 via a noble metal ring 4 "is detachably fitted.

[0015]

As described above, in the method of manufacturing a noble metal decorative component according to the present invention, when joining noble metals, a laser is applied to the joint of the noble metal, and only the portion irradiated with the laser is irradiated. The welding is performed by rapidly heating the steel, and when the laser irradiation is completed, it cools down naturally, so that it does not give much heat conduction to the parts other than the welded parts. There is an advantage that burnout of rubber or rubber is eliminated.
