Description

The globular outfit element for metal net chain's ornamental accessary's use

The present invention is a high-quality spherical design device for decorative accessories, such as jewelry, ornaments, ornaments, etc. rich in design than other design devices, made of gold chain made of metal meshes such as gold, silver, stainless steel, and general metal; The present invention relates to a method for efficiently and quickly manufacturing this design element.

Among spherical design elements for jewelry, those made of perforated plates are compared with the present invention. The design device of perforated board is low in ornamentation as a decoration or ornament because of lack of glare and glare rather than showing the design by the size and arrangement of holes.

In addition, since burrs are formed on the back of the hole during the drilling process, post-processing is required to remove them, and the welding of the folded ends is necessary when rolling the plate into a round pipe, so productivity is low and such manufacturing costs are high.

The present invention is to provide a spherical design device having a rich design feeling that surpasses the quality, decoration, and manufacturing efficiency using other gold pipes, and a method for efficiently and qualityly manufacturing the design device.

The present invention provides a process for forming a preliminary gold chain tube spirally wound around a long metal rod having a higher melting point than a powder welding agent in a spiral direction, and a mesh of the preliminary gold chain tube obtained in the preceding step. Powder welding agent buried with gold metal powder welding agent between components, and the preliminary gold chain tube with powder welding agent is heated together with mandrel to remove powder welding agent between the gold chain and the gap between the gold chain elements. The gold chain pipe shaping process of melting and attaching and shaping the gold chain pipe to form a gold chain pipe, the cooling and the core rod removing process of cooling the gold chain pipe shaped by welding and removing the mandrel, and inserting the gold chain pipe into the rolling machine and A method of manufacturing a spherical design element made of a gold chain, which is formed by a molding step processed into a spherical design element such as a round circle or an elliptical sphere; And a gold chain design element 8 having a hole 9 obtained therefrom.

Hereinafter, a process of manufacturing a decorative element for decorative or decorative gold chain intended by the present invention will be described with reference to FIG. 1.

Step 1-Creation of Reserved Gold Chain Pipe

A preliminary gold chain pipe (3) is made of gold chain (1). Here, the gold mesh chain (1) literally refers to chains for ornaments or ornaments woven from metal yarn material. Gold chains having this purpose (1) are generally made of ordinary metals, which are easily processed, including precious metals such as gold, silver and copper.

The precondition for making it a design chairman is to make a gold chain pipe (3) from a gold chain (1). In order to make a high-quality high-quality gold chain tube (3) with a gold chain (1), the elements of the gold chains of each line as well as adjacent gold chains should be straightened without overlapping. This requires a mandrel (2).

The core rods 2 are generally round rods, elliptical rods, or angular rods, which are also made of metal. Among the metals, the metal has a higher melting point than the powder welding agent used when shaping the preliminary gold chain tube 3. Metal core rods having a lower melting point than powder welding agents are not considered because they may be bonded to gold chains when the gold chain tubes are heat-treated to melt powder welding agents and weld adjacent elements of the gold chains 1 to each other. The core element 2 is inserted into the preliminary gold chain tube 3 to stretch the chain element.

Second Process-Applying Powder Welder

The preliminary gold chain tube 3 obtained in the previous step is not marked by the conventional welding method known so far, and should be welded quickly. Therefore, powder welding agent 4 is used. The powder welding agent 4 is a welding agent particularly suitable for the chain only. Put the preliminary gold chain tube (3) in the container (5) containing the core welding powder (4) together with the core rod (2) and rolled around, and the particles of the powder welding agent (4) were It is buried so as to fit in the gap between the chain elements, and taken out to shake off any excess powder welding agent stuck in the chain elements.

Process 3-Formation of the Gold Chain Pipe

The preliminary gold chain tube (3) having a length of 40 to 80 cm obtained in the previous step is provided with a core rod (2) and a tunnel heater (6) such as a high-frequency processor maintained at 400 to 700 ° C lower than its melting point for 4 to 6 minutes. The powder welding agent 4 sandwiched between the gold chains and the chain elements is completely melted, and the adjacent ones stick to each other to be hardened by the gold chain pipe 7.

Process 4 -cooling of the gold chain and removing the mandrel

Since the core rod 2 is unnecessary in a subsequent process, after cooling the gold chain tube 7 obtained through the chain tube shaping process, the core rod 2 is collected.

5th process: shaping of design element

When the gold chain tube 7 is put into a rolling machine with a pressure roll installed at the same pitch on the rotating shaft and gradually pressurized with a predetermined pressure, the pressed mark is cut off at a constant pitch like a bean pod, and is close to a bead shape 7a. A design element is obtained.

Alternatively, as shown in FIG. 2, when the small diameter hollow tube 8 is put in the gold chain tube 7 and put into a rolling machine and pressurized, the gold chain tube 7 of the pressed portion is reduced in diameter, and the hollow tube 8 is spontaneously moved to the center thereof. It moves, and stops pressurizing in the state which the gold chain pipe 7 touches the outer peripheral surface of the air pipe 8, and crushes it with a slightly strong pressure. Then, a preliminary design element having a hollow tube 8 in the center is obtained. Either way, the pressure on the gold chain tube 7 is adjusted to the dimension of the design element to be obtained.

When the concave portion of the semifinished product is cut by a cutter, a gold chain design element 9 is obtained. The design element 9 is formed with a hole 10 in the axial direction.

The design element 9 has a unique shape of a gold chain having the same standard and has a well developed natural surface irregularities, so that the design element is much richer than other design elements.

3 shows an example of ornaments such as necklaces, arms, and decorative belts made using the design element 9, and can be widely used for decorative strings, handbag straps, and the like.

As described above, the present invention uses a gold chain to form an invariant gold chain tube, and the gold chain tube is put into a rolling machine to be manufactured as a preliminary spherical design element at a predetermined pitch. High-quality design elements can be manufactured very efficiently and quickly.

In addition, it is possible to provide a gold chain design device having a superior design feeling compared to a conventional metal drill control device.
