Abstract
The invention relates to the technical field of accessories, in particular to a preparation method of a hollow silver necklace. The hollow necklace is formed by a hollow pipe. A preparation method of the hollow pipe includes the following steps of firstly, conducting punching, wherein a silver block is cast and pressed into a silver strip through a tablet press; secondly, conducting quenching, wherein quenching is conducted on the silver strip obtained through pressing in the first step; thirdly, conducting welding, wherein the edges of the silver strip subjected to quenching are welded together in the length direction of the silver strip to form a hollow pipe body; fourthly, manufacturing the hollow pipe, wherein the welded hollow pipe body is manufactured into the hollow pipe, the necklace is formed by the hollow pipe, ground and polished, and then the finished product is obtained. The necklace prepared through the method is novel and unique in style and high in modeling three-dimensional sense; due to the hollow tubular structure, the weight is small, materials are saved, and cost is saved for wearers.
Description
Technical field
The present invention relates to ornaments technical field, be specifically related to a kind of preparation method of hollow silver necklace.
Background technology
Silver jeweleries in history once by the favor of many nationalitys, becomes one of carrier of multiculture interchange as a kind of cultural phenomenon.In this carrier, merge " the ear shelves " that have from Southern Minority, originate from " escape " of northern ethnic group, and " step is shaken ", the dragon, phoenix, ripple sample etc. of " five soldiers wear " and Chinese tradition that derive jewelry from ancient times and come.Silver jeweleries adopts various processing technology, and the Silver Jewelry be processed into is of a great variety, is substantially divided into ear pendant, necklace, jewelry, foot decorations and dress ornament 5 large classes.
Silver jeweleries in the history of state-owned thousands of years, feudal society and the pre-peaceful liberation period China common people family, owing to living in want, gold is difficult to have in the common people, therefore the common people make the preferred material of jewellery is the moderate silver having again texture naturally, thus silver jeweleries culture is taken root among the people.
At present, silverware style is exquisite, immediately following fashion, material has neutral original texture, style more focuses on leisure individual character, more courageously exaggerates in design, be more suitable for daily wearing dressing, the fashion intelligent gang of big and medium-sized cities, buys number cover fashion silver jeweleries each season, the mood that the different clothes that are used for arranging in pairs or groups are different with expression.Silver jeweleries breaks traditions, and fully caters to modern's showing personality, immediately following the feature of fashion.Along with trend of back-to-ancients is popular in recent years, some handicrafts pseudo-classic, modelled after an antique and ornaments enjoy people to pursue.
It is but the silver jeweleries being worn on neck mostly at present is silver-colored chain collocation pendant, moulding old stuff, single.Fine silver-colored chain lacks third dimension, cannot meet consumer demand.
Summary of the invention
The object of this invention is to provide a kind of preparation method of hollow silver necklace, the fashionable uniqueness of silver-colored necklace that the method prepares, moulding third dimension is strong, and the structure of hollow tubular, lightweight, saving material, is also that wearer is cost-saving.
In order to realize above object, the present invention adopts following technical scheme:
A preparation method for hollow silver necklace, described hollow necklace is made up of hollow pipe, and the preparation method of described hollow pipe comprises the following steps:
