Thin bead forming process

Abstract

Disclosed is a thin chain bead forming process for forming shells of chain beads. The thin chain bead forming process comprises the following steps that (1) gold melting is conducted; (2) tube-drawingforming is conducted; (3) seamless welding is conducted, and thus a hollow tube is formed; (4) tube-drawing forming is conducted; (5) preliminary die pressing is conducted, specifically, the hollow tube is fixed to a clamping device, the clamping device clamps the hollow tube to enable the hollow tube to be subjected to die pressing on a first die, and thus a drum-shaped tube is formed; (6) die pressing is conducted for the second time, specifically, the drum-shaped tube treated in the step (5) is fixed to the clamping device, and the clamping device clamps the hollow tube to enable the hollow tube to be subjected to die pressing on a second die; (7) the surface is treated, specifically, the surface of the spherical tube is polished to be smooth; and (8) the tube is cut. Preliminary forming of the spherical tube is completed through first-time die pressing, in secondary die pressing, machining is conducted through different sets of forming grooves with the spherical radii being decreased gradually, and accordingly forming of the thin chain beads is completed; and under the condition that the appearance size is guaranteed, the weight of each chain bead is reduced effectively, and the product price is lowered.

Description

technical field [0001] The invention relates to a gold ornament forming process, in particular to a thin-shaped chain bead forming process. Background technique [0002] The quality of life of modern people has improved, so in addition to choosing appropriate and decent clothing in daily life, in order to highlight personal characteristics, they will wear different decorations to show their own taste and distinguish them from others. There are many kinds of decorations, More commonly used, including rings, necklaces, earrings, bracelets and other decorations. Through the matching of decorations, personal style and overall visual beauty can be enhanced. [0003] The existing decorative chain beads are becoming thinner and thinner. Manufacturers not only effectively improve the visual effect of the chain beads, but also reduce the thickness of the chain beads by increasing the volume of the chain beads and reducing the thickness of the chain beads. weight, thereby reducing t...

AI Technical Summary

Problems solved by technology

[0003] The existing decorative chain beads are becoming thinner and thinner. Manufacturers not only effectively improve the visual effect of the chain beads, but also reduce the thickness of the chain beads by increasing the volume of the chain beads and reducing the thickness of the chain beads. weight, thereby reducing the cost of the beads and increasing the selling point of the product. However, the existing decorative beads are becoming thinner and thinner, but affected by the technology, the thickness of the product cannot be made too thin, otherwise the product During the pressing process, the product will break, which will cause the product to be scrapped and increase the manufacturing cost of the product
