DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. First, it should be noted that, in the drawings, the same components or parts have the same reference numerals as much as possible. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted so as to avoid obscuring the subject matter of the present invention.

FIG. 1 shows a process flow chart of an accessory manufacturing method according to the present invention. As shown in FIG. 1, it can be seen that the accessory manufacturing method of the present invention comprises a series of processes such as rolling, punching, molding, , The preferred implementation of each process is as follows.

The rolling process is a pretreatment process for obtaining an accessory material (M), and a flat plate-like material having a uniform and constant thickness is processed by passing a noble metal material having a high elongation rate between rolling rollers (R) .

The punching process is a process for implementing an accessory material (M), and is a process for cutting a noble metal material processed into a plate shape into a certain shape by using a piercing punch, which is moved up and down by a die and a manual means, A plurality of accessory materials (M) are obtained. The accessory material M thus obtained is uniform in shape and uniform in thickness, and is almost the same in weight.

The forming process is a process for pressing the accessory material (M) to form a pattern or a letter of a specific pattern on the surface. The process is divided into 1 to 6 steps. First, the accessory material (M) A molding jig J having a molding hole H capable of accommodating the outer shape of the lower block B2 is placed on the upper portion of the lower block B2 so that the upper surface of the lower molding plate J at the center of the forming hole H. (Step 1)

The accessory material M is put into the molding hole H of the molding jig J located at the upper portion of the lower block B2 so that the accessory material M is mounted on the upper surface of the molding lower pressurizing plate P2. Step 2)

The upper block B1 provided with the molding upper pressure platen P1 is first lowered so that the upper molding platen P1 is pressed against the lower press platen P2 for molding The upper surface of the accessory material M placed on the upper surface is pressed so that the accessory material M is pressed between the upper and lower pressing plates P1 and P2 so that the upper pressurizing plate P1 is formed on the upper surface of the accessory material M. [ So that the pattern or character of the specific pattern formed in the step (3)

When the pressurization of the accessory material M is completed, the upper block B1 is raised and lowered (step 4), and then the molding jig J is raised and lowered (step 5)

The upper block B1 is lowered secondarily after the molding jig is raised and lowered so that the upper molding plate P1 presses the accessory material M interposed in the center of the molding hole H of the molding jig J, The molding process for the accessory material (M) is terminated by discharging down the hole (H) (step 6).

The post-processing step is to finish the molding and to bend the accessory material (M) having a pattern or pattern of a specific pattern on the surface thereof in the form of a ring to realize a ring or a bracelet.

On the other hand, accessories require a separate post-processing such as a medal or a nameplate, and the manufacture ends in the molding process.

The method of manufacturing a noble metal accessory according to the present invention is capable of manufacturing an accessory in which a pattern or pattern of a specific pattern is formed by directly pressing an accessory material M having the same shape and weight (see FIG. 7) (Weight and shape) can be produced quickly and accurately. In particular, accessories are manufactured by pressing the accessory material (M) of a certain weight as it is. Therefore, there is no need to worry about weight loss due to a pattern or a piece of characters, (bur or iridium), it is possible to greatly shorten the working time.

2 is a perspective view showing a preferred embodiment of a precious metal accessory molding apparatus 10 according to the present invention. As shown in the drawing, a molding apparatus 10 includes a lower portion 20 fixed on a worktable 20 having a flat upper surface, A molding lower press plate P2 is formed on the upper part of the block B2 and a molding jig J provided above the lower block B2 is provided with a molding hole (H).

The wings W1 and W2 of the molding jig J are fixed to the lifting rod 41 of the lifting cylinder 40 fixed to the work table 20 and the lifting cylinder 40 is operated to rotate the forming jig J, Up and down.

A fixing plate 22 is provided on the upper end of the support post 21 provided at the rear of the lower block B2 to provide a pressing cylinder 30 on the fixing plate 22, The upper block B1 is fixed to the lower block 31 so that the upper block B1 is raised and lowered by the operation of the pressurizing cylinder 30. [

A molding upper pressure plate P1 is provided at the bottom of the upper block B1 and a pattern or letter mark of a specific pattern made of a negative or positive angle is formed on the bottom of the molding upper pressure plate P1.

The molding apparatus 10 having the above-described configuration is configured such that the molding jig J is positioned above the lower block B2 and the upper surface of the molding lower presser plate P2 of the lower block B2 is molded The accessory material M is put into the molding hole H of the molding jig J in a state where the accessory material M is positioned at the center of the hole H (see FIG. 3 [B] The upper block B1 fixed to the pressurizing rod 31 is lowered first and the upper block B1 is lowered to the lower end of the upper block B1, The upper pressing plate P1 is drawn into the forming hole H of the jog J so that the upper pressing plate P1 presses the upper surface of the accessory material M so that the accessory material M is pressed against the upper, (See Fig. 3 [C] and Fig. 4). At this time, the upper surface of the upper pressing plate P1 is pressurized between the upper surface P1 and the lower surface P2 A pattern or character of a specific pattern is formed on the surface of the accessory material M (see FIG. 7).

When the pressurization is completed, the upper block B1 is raised and lowered by the driving of the pressurizing cylinder 30. At the same time, the molding jig J fixed to the lifting rod 41 is lifted and lowered by driving the lifting cylinder 40 The pressurized accessory material M is separated from the lower block B2 as shown in Figs. 3 (A) and 5 (A) to be.

When the elevating movement of the elevating cylinder 40 is stopped, the pressurizing cylinder 30 is driven so that the upper block B1 fixed to the pressurizing rod 31 is lowered for the second time, and the upper pressurizing plate P1 And the accessory material M is discharged downward into the molding hole H by pressing the accessory material M interposed in the center of the molding hole H of the molding jig J After the completion of the molding of the accessory material M, the upper block B1 and the molding jig J are returned to their initial positions by driving the pressurizing cylinder 30 and the lifting cylinder 40.
