AI Technical Summary

Technical Problem

Existing methods for manufacturing ball chains for jewelry face challenges such as extended production time, variability in product quality due to manual pattern formation, and difficulty in forming cutting patterns on the outer side of the balls, as well as potential deformation or damage to link chains during the ball forming process.

Method used

A method involving forming a plate into a tubular shape, then into a ball shape using a die, applying a cutting pattern by numerical control, and separating the balls while connected, followed by connecting a link chain to the wire and transferring the balls to form a combined ball-link chain.

Benefits of technology

Enables efficient production of a ball chain with a cutting pattern by automating pattern formation and ensuring precise separation and transfer of balls to a link chain, reducing production time and ensuring consistent quality.

Abstract

The present invention relates to a method for manufacturing a ball chain, and more specifically, to a method for manufacturing a ball chain for jewelry having a cutting pattern formed thereon, wherein a plate is formed into a tubular shape and then formed into a ball shape using a ball forming die, a cutting pattern is processed on the outer surface using a cutting pattern forming machine operated by numerical control, and the balls are processed to be individually separated using a separate cutting machine. To this end, the present invention comprises: a wire supply step for supplying a wire; a plate feeding and tube forming step for feeding a plate into the outside of the supplied wire and forming the plate into a tube shape; a ball forming step for forming the plate formed into a tube shape into a ball shape using a ball forming die, but forming it in a connected state without being completely separated; a cutting pattern forming step for automatically forming a cutting pattern by numerical control using a cutting pattern forming machine on the outside of the formed ball; a cutting separation step for cutting the connecting part of the ball with the formed cutting pattern to completely separate it into multiple parts; a link chain connecting step for connecting a link chain to the end of the wire on which multiple balls are fitted; a ball link chain side transfer step for moving the balls fitted on the wire to the link chain side; and a recovery step for separating the link chain from the wire and recovering it when the balls are transferred to the link chain side.
