Thin-wall gold tube automatic shrinking machine

Abstract

The invention discloses an automatic thin wall gold tube necking machine, belonging to the technical field of jewelry processing equipment. The automatic thin wall gold tube necking machine comprises a rack, wherein the rack is provided with a feed system; the downstream of the feed system is provided with a mould system used for stamping a tube billet of a thin wall gold tube into bead strings; the feed system comprises an axial feeding device used for conveying the tube billet of the thin wall gold tube, a rotation feeding device used for rotating the tube billet of the thin wall gold tube in an intermittent way and a clamp device used for clamping or loosening the tube billet of the thin wall gold tube. According to the automatic thin wall gold tube necking machine, feeding, rotating clamping and stamping of the tube billet of the thin wall gold tube are automatic, so automatic feeding and stamping of the processing of the tube billet of the thin wall gold tube are realized. When the stamping is performed, the tube billet of the thin wall gold tube is clamped, so the quality of the produced bead strings is stable. In the machining process, stock lifting for the tube billet of the thin wall gold tube is not needed, so the working efficiency is significantly improved.

Description

technical field [0001] The invention belongs to the technical field of jewelry processing equipment, and in particular relates to an automatic necking machine for thin-walled gold tubes. Background technique [0002] Precious metal jewelry is more and more popular with consumers due to its dazzling appearance. There are more and more styles of precious jewelry on the market, and the categories are becoming more and more complex. Such as precious metal jewelry, marquise-shaped monomers are generally processed into bead strings from thin-walled gold tubes, and then the bead strings are cut into individual bead string monomers. [0003] At present, for processing thin-walled gold tubes into bead strings, a combination of manual feeding and a small manual punching machine is usually used. The punch of the punching machine is equipped with an upper mold with a profile. During production, the operator feeds the material with one hand. One end of the gold tube billet to be process...

Problems solved by technology

The disadvantages of this processing method are: due to the manual feeding and rotation of the gold tube billet and the operation and control of the punch, it is easy to cause inaccurate feeding position and low forging precision, and it is difficult to maintain uniform product specifications and quality. , and the production efficiency is low

However, during the operation of the jewelry beading machine, after the forging is finished, the metal tube blank needs to be lifted by the auxiliary lifting device every time, and then the axial feeding device can transport the metal tube blank downward. It affects the production efficiency; and when the die forging device is forging the metal tube blank, the metal tube blank is not fixed, and the forging position of the gold tube is unstable, resulting in unstable quality of the produced bead string
