Problems solved by technology

[0003] The technical problem to be solved by the present invention is to overcome the disadvantages of the large loss of jewelry chains made of solid metal wires, the small volume of jewelry chains obtained from gold per unit weight, and the lack of soft and beautiful shapes, and provide a jewelry chain made of hollow round wire and The production method enables the prepared jewelry chain to have larger volume, less loss, more compact structure, softness and strong texture under the same weight, which greatly improves the utilization rate of gold

Embodiment Construction

[0023] The present invention will be further described below in conjunction with accompanying drawing.

[0024] Such as figure 1 As shown, the gold is pressed into a thin sheet with a thickness of 0.3mm, one end of which is rolled into a circle, passed through a wire drawing die with a diameter of 2.0mm, and can be drawn into a hollow round wire with a diameter of 2.0mm; depending on the diameter of the wire drawing die, Different models, that is, hollow round wires with different diameters, can be drawn.

[0025] Such as figure 2 As shown, the drawn hollow round wire is wound on the smooth winding mandrel, and the speed is kept uniform during winding.

[0026] Such as image 3 As shown, after winding, cut the hollow round wire along the direction of the winding mandrel to make an open hollow link of the same size and shape.

[0027] Such as Figure 4-5 As shown, in order to heat up the cooled and hardened gold and make it easier to carry out the next step, therefore, te...

Abstract

The invention relates to a jewelry chain and a manufacturing method thereof. The jewelry chain is formed by connecting hollow chain rings in series. The manufacturing method comprises the following steps of: processing gold into hollow round wires through the processes of sheet rolling, wire drawing and the like; and then performing coiling, downward breaking, serial connection, molding and the like. The jewelry chain and the manufacturing method have the advantages that: compared with the conventional jewelry chain made of solid metal wires, by using the hollow round wire manufactured by the method of the invention, the jewelry chain with a larger volume, smaller losses, softness and compactness can be obtained by using the gold with the same weight.

Description

technical field [0001] The invention relates to gold jewelry chains such as necklaces and bracelets and a production method thereof. Background technique [0002] In the field of jewelry making, necklaces and bracelets have many styles and production methods, and the most important purpose is to obtain jewelry chains with larger volume, less wear and tear, soft and comfortable. However, the width, thickness and softness of various jewelry chains made by traditional solid metal wires still cannot achieve the desired effect, and the manufacturing loss of jewelry chains made by solid metal wires is large, and the gold per unit weight can obtain Expressiveness (appearance, texture) is not ideal. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the disadvantages of the large loss of jewelry chains made of solid metal wires, the small volume of jewelry chains obtained from gold per unit weight, and the lack of soft an...
