Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a ring jewel crimping device for fixing a jewel such as a diamond to a ring.

BACKGROUND TECHNOLOGY Conventionally, the process of fixing jewelry to a ring has been carried out manually by craftsmen, or by using a press-type device using an air cylinder or an oil cylinder. As shown in Fig. 8, the manual method involves placing a heavy steel ball with multiple grooves on its surface on the cushion, and inserting the lower end of the stand into the grooves. A stand with a tip to which a ring to be processed can be detachably attached is erected on the surface of the steel ball, and the steel ball is placed on a cushion in order to arbitrarily change the working angle with respect to the tip of the stand as seen from the craftsman's point of view. While turning the stand, the jewel was fitted into the fitting hole of the pedestal of the ring to be processed, which was attached to the tip of the stand, and the periphery of the fitting hole was swaged using nippers.

Problems to be Solved by the Invention The above-mentioned manual caulking of gemstones onto rings to be processed is performed by the craftsmen using a caulking method suitable for the type and shape of each type of gemstone, so the finished product is in good condition. It is. However, this manual work requires many years of skill and a great deal of effort and time, and especially in the case of a ring as shown in Fig. 7, in which multiple jewels are fixed to one ring, the workpiece ring Since the jewels inserted into the fitting holes are likely to fall out, it is necessary to perform fitting and caulking for each fitting hole, which inevitably results in high labor costs and expensive products. It was hot. In addition, the press-type caulking device cannot finely adjust the caulking force or the caulking direction, so the jewelry itself is often damaged, and it is particularly unsuitable for diamonds. .
