JP2001137018A - Stone clamping tool - Google Patents

Abstract

PROBLEM TO BE SOLVED: To manufacture a stone clamping tool that is made of two press- machining parts, can reduce cost, and does not require much time and labor without producing the stone rock-fill of jewels and cut glass using a conventional casting process requiring much time and labor. SOLUTION: Cylindrical parts with a stepped, hollow nib and a hollow seat are manufactured by clipping drawing due to pressing so that stone can be clamped easily, and jewels and cut glass are pinched between them and the claw is bent by hand press for assembly, thus reducing machining labor and time, and cost.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a press process using a thin metal plate such as gold, platinum, silver, brass, or aluminum as a stone frame to attach jewelry or cut glass to a pendant head, earrings, or piercings. It is related to stone fasteners.

[0002]

2. Description of the Related Art Conventional stone fasteners are made of cast, thick walled jewelry and cut glass, which are fixed by enclosing rings or nail fasteners. However, processing techniques are also difficult and time-consuming.

[0003]

DISCLOSURE OF THE INVENTION The present invention eliminates the drawbacks of the present invention and eliminates the drawbacks of the present invention by using a pressing technique so that the stone can be easily fixed. We made research with the task of making a perforated washer and holding a jewel or cut glass in between and folding and fixing the nail.

[0004]

[Means for Solving the Problems] In order to easily perform stone fixing, a cylindrical part with a stepped perforated claw and a perforated washer are manufactured by press working, and what is ideal between a jewel and a cut glass is sandwiched. As a result of experiments and theory, it was found that it is best to make a mold and bend and fix the nail with a hand press.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Since the present invention has the above-described configuration, a nail is bent by a hand press with a jewel or a cut glass sandwiched between a pressed cylindrical part with a stepped perforated claw and a perforated washer. It can be fixed stably and the pressure can be adjusted, so the product is hardly damaged and can be made lighter than cast products

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In order to carry out the present invention, first, a press die was punched out, and a thin plate of various metals was pressed to produce two types of parts: a cylindrical part with a stepped perforated claw and a perforated washer. . In the case of a small amount, this method may be used, but since it takes time and costs are high, various methods such as making a progressive press die for mass production are performed so that mass production can be performed next.

[0007]

(1) Since the present invention is configured as described above, the completed stone retaining frame can easily and stably fix the jewelry by two parts, and the jewelry can be fixed by the light picked up from the back. The crown shines and looks beautiful, and it can be connected by brazing each one of the nails that hold the perforated washer,
Jewelry can be made with variety. Weight can be reduced to about 1/10 of material compared to cast products, helping to reduce costs, easy to assemble, shortening production time and mass production.
