Embodiment 1

[0035] The invention discloses a method for preparing a hollow silver collar. First, the silver block is made into a hollow round tube, and then the hollow round tube is made into a circular collar.

[0036] Wherein, the preparation method of hollow circular tube is as follows:

[0037] (1) Stamping: take 990 silver materials and melt and cast them into silver bars with a width of 4cm, a thickness of 2cm, and a length of 60cm, and press the cast silver bars into a thickness of 0.5mm by a tablet press, wherein, after pressing to a thickness of 1.5cm At the same time, the silver bar needs to be quenched once, and the remaining material on both sides of the silver bar should be collected inward on the plodder, and then continue to be pressed;

[0038] (2) Quenching: the silver bar obtained by pressing step (1) is quenched, the quenching temperature is 750°C, and the quenching time is 10min, until the surface of the silver bar is red;

[0039] (3) Welding: Use an automatic weldin...

Embodiment 2

[0056] The invention discloses a method for preparing a hollow silver collar. First, the silver block is made into a hollow round tube, and then the hollow round tube is made into a circular collar.

[0057] Wherein, the preparation method of hollow circular tube is as follows:

[0058] (1) Stamping: Take 990 silver materials and melt and cast them into silver bars with a width of 3.8cm, a thickness of 1.8cm, and a length of 55cm, and press the cast silver bars into a thickness of 0.6mm through a tablet press. When the thickness is 1 cm, the silver bar needs to be quenched once, and the remaining material on both sides of the silver bar should be retracted on the plodder, and then continue to press;

[0059] (2) Quenching: the silver bars obtained by pressing step (1) are quenched, the quenching temperature is 780° C., and the quenching time is 9 minutes until the surface of the silver bars is red;

[0060] (3) Welding: Use an automatic welding machine to weld the quenched si...

Embodiment 3

[0071] The invention discloses a method for preparing a hollow silver collar. First, the silver block is made into a hollow round tube, and then the hollow round tube is made into a circular collar.

[0072] Wherein, the preparation method of hollow circular tube is as follows:

[0073] (1) Stamping: Take 990 silver materials and melt and cast them into silver bars with a width of 3.5cm, a thickness of 2.2cm, and a length of 65cm, and press the cast silver bars into a thickness of 0.4mm through a tablet press. When the thickness is 1 cm, the silver bar needs to be quenched once, and the remaining material on both sides of the silver bar should be retracted on the plodder, and then continue to press;

[0074] (2) Quenching: the silver bars obtained by pressing step (1) are quenched, the quenching temperature is 800° C., and the quenching time is 8 minutes until the surface of the silver bars is red;

[0075] (3) Welding: Use an automatic welding machine to weld the quenched si...

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 [0001] The invention relates to the technical field of ornaments, in particular to a method for preparing a hollow silver collar. Background technique [0002] As a cultural phenomenon, silver jewelry has been favored by many nations in history and has become one of the carriers of multicultural exchanges. In this carrier, there are "ear files" from the southern minorities, "jumping" originated from the northern minorities, and "buyao", "wubingpei" and Chinese traditional ornaments derived from ancient ornaments. Traditional dragon, phoenix, scale patterns and so on. Silver jewelry adopts various processing techniques, and there are many types of silver jewelry processed, which are basically divided into five categories: earrings, neck ornaments, hand ornaments, foot ornaments and clothing. [0003] Silver jewelry has a history of thousands of years in China. In the feudal society and before the liberation of ordinary people in China, gold was difficult for...
