Abstract

The invention discloses a gold and silver hollow bracelet processing technology and belongs to the technical field of jewelry processing technologies. The processing technology comprises the following steps: preparing material: according to the specifications for processing gold and silver hollow bracelets, preparing sheet material with corresponding specifications; manufacturing a pipe: processing the sheet material into a round pipe with a gap and straightening the round pipe; annealing; calibrating: straightening the gap; welding without welding material: eliminating gap through high-temperature heating to form a gapless round pipe; cutting: cutting the gapless round pipe according to the finished size of a gold and silver hollow bracelet, and polishing two ends of the gapless round pip; pre-forming: processing the gapless round pipe into an open type circular ring, and forming a closed circular ring by performing high-temperature heating on the open type circular ring; shaping: shaping the shape of the closed circular ring until specified requirements are met; forming: processing the closed circular ring into a hollow bracelet with elliptic sections. Through the processing steps, since a only a piece of sheet material is needed, the hollow bracelet can be manufactured, the processing technology is reduced, the processing efficiency is improved, the forming effect is good, and meanwhile, the gap is closed automatically through high temperature, so that welding without welding material is achieved, and the purity and fineness are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of jewelry processing technology, and in particular relates to a processing technology of gold and silver hollow bracelets. Background technique [0002] Gold and silver hollow bracelets are one of many bracelet styles and are popular with the public because of their light weight and elegant appearance. Traditional gold and silver hollow bracelets are usually processed separately from the upper and lower mother bodies whose cross-sectional shapes are arc-shaped. Combine them together so that the middle of the combination forms an elliptical hollow. At present, the combination of the upper parent body and the lower parent body is combined in the form of manual welding. When welding, two welds need to be welded with flux. At the same time, the color and purity of jewelry will be affected by the flux during the welding process. The purity of gold and silver hollow bracelets cannot reach a certain standard, esp...
