Description

Technical Field [0001] The present invention relates to a stand manufacturing method of a display device,

The present invention relates to a method of manufacturing a display device, and more particularly, to a display device capable of simplifying a manufacturing process by a simple structure to provide convenience in fabrication and minimizing post- To a stand manufacturing method.

2. Description of the Related Art In general, a display device such as a TV or a monitor of a computer is provided with a stand or the like for seating on a table.

1, an example of a typical stand 10 includes a main body 11 and a cover 12 coupled to the main body 11. The main body 11 includes a body 13, And a pair of leg portions 15 and 16 extending to a predetermined length on both sides of the body 13 at predetermined angles are provided on the other side of the body 13 A conventional method of manufacturing such a conventional stand 10 is to make a material such as synthetic resin or aluminum by molding such as die casting using a metal mold having a size corresponding to the sectional shape of the stand 10.

However, in the case of the conventional stand 10, the length of the leg portions 15 and 16 is made to be long enough to stably support the leg 10 according to the size of the display device. There is a problem that the cost required for manufacturing the mold and the manufacturing cost are complicated.

In addition, since the surface of the conventional stand 10 can not be used as it is for the appearance of the molded product, the plating process is performed through a post-process or the like, thereby increasing the manufacturing cost. And the thickness of the main body 11 and the cover 12 itself is made thin, so that the rigidity thereof is weak.

Korean Patent Publication No. 10-2008-023983 (2008. 03. 17.)

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and it is an object of the present invention to eliminate manufacturing method using a mold so that it is not necessary to produce a large- The present invention provides a method of manufacturing a stand of a display device which can simplify a process to a great extent and provide convenience in fabrication while minimizing post-processing operations while being excellent in rigidity.

According to an aspect of the present invention, a body 31 having a predetermined thickness and area is fabricated by a raw material 20, and a coupling portion 32 having a relatively thin thickness is formed on one side of the body 31 (ST100);

A step (ST200) of forming a pair of divided parts (21, 22) which are divided in the longitudinal direction on the other side of the body (31) so as to face the engaging part (32);

(ST300) forming the V-shaped leg portions (33, 34) by bending and pulling the divided portions (21, 22);

And a step (ST400) of completing the stand (30) by forging or cutting the entirety of the raw material (20) including the leg portions (33, 34) .

According to another aspect of the present invention, in the step ST200 of forming a pair of divided portions 21 and 22 on a part of the body 31, And a plurality of cut-away grooves (23) are formed along the plurality of cut-out grooves (23).

In the step ST100 of forming the body 31 and the engaging portion 32 by the raw material 20, the side surface of the raw material 20 is joined to the engaging portion 32, Is tapered so as to reach the leg portions (33, 34).

As described above, according to the present invention, the stand 30 can be manufactured by a method of forming the leg portions 33 and 34 extending to a predetermined length by a manufacturing process of cutting and pulling the block-shaped raw material 20 , It is not necessary to use a large metal mold corresponding to the extension length of the leg portions 33 and 34 as in the prior art, and the cost and manufacturing hassle of manufacturing the metal mold are solved, The stand 30 is manufactured through a manufacturing process such as pressing or forging of a single raw material 20, so that the stand 30 itself has an excellent stiffness and minimizes the surface treatment.

Further, the present invention is characterized in that when the bar-shaped corrugated portions 21 and 22 are preliminarily manufactured for manufacturing the leg portions 33 and 34, the corrugated portions 21 and 22 are alternately extended in the width direction It is possible to form the leg portions 33 and 34 having sufficient length even by the short raw material 20 while easily stretching the wrinkle portions 21 and 22 by forming the cut- have.

2 is a perspective view showing an embodiment of the present invention.
Figure 3 is a flow chart of the process of the present invention,
4 is a perspective view illustrating a process sequence according to an embodiment of the present invention.

The objects, features and advantages of the present invention will become more apparent from the following detailed description. Hereinafter, description will be made with reference to the accompanying drawings.

2 to 4 show a preferred embodiment of the present invention. As shown in FIG. 2, the stand 30 of the present invention includes a body 31 having a substantially triangular cross-section and a fastening hole 35 formed at one end thereof, so that a display device or a bracket A pair of leg portions 33 and 34 extending in the form of a long bar are formed on the other two ends of the body 31. The stand 30 has a pair of leg portions 33, Will be described with reference to FIGS. 3 to 5. FIG.

3 and 4, the present invention includes a step ST100 of forming a body 31 and a coupling portion 32 by a raw material 20, a step ST100 of forming a pair (ST300) of forming the leg portions (33, 34) by the divided portions (21, 22), forming the divided portions (21, 22) (ST400) of completing the stand (30) by forging or cutting the entire surface of the stand (30).

Specifically, in the step ST100 of forming the body 31 and the engaging portion 32 by the raw material 20, a raw material 20 made of a metal such as aluminum in the form of a block having a roughly rectangular cross section At this time, the raw material 20 has a predetermined thickness and a relatively small thickness of an engaging portion 32 (see FIG. 3) formed on one side of the body 31 having a certain area and thickness by extrusion, pressing, The joining portion 32 may be provided with a work for forming a fastening hole 35 or the like in a subsequent step.

The shape and size of the raw material 20 itself are changed by cutting, bending, or tensile work in the manufacturing process, and the area, thickness, and cross-sectional shape of the thickness portion are optimized Preferably, the raw material 20 is tapered so as to extend from the engaging portion 32 to the other end so that the leg portions 33 and 34, which will be described later, are gradually thinned Thereby providing convenience in operation.

Also, in step ST200 of forming a pair of divided parts 21 and 22 on a part of the body 31, a part of the raw material 20 prepared in the previous stage is cut to be bisected, The divided portions 21 and 22 are formed to extend from the opposite ends of the coupling portion 32 by a predetermined length.

Preferably, when the dividing portions 21 and 22 are formed, a cutout groove 23 extending in the width direction is formed on the dividing portions 21 and 22, And a plurality of cut-away grooves 23 extending in the width direction are formed on both sides of the cut-off portions 21 and 22 so as to be offset from each other, 21, 22) can be seen as being formed in a corrugated state.

In the step (ST300) of forming the leg portions (33, 34) by the divided portions (21, 22), the divided portions (21, 22) manufactured in the previous stage are bent to form a certain angle, It is possible to form the leg portions 33 and 34 elongated to a predetermined length by stretching or to bend at a predetermined angle after the dividing portions 21 and 22 are first stretched. It does not matter if it changes.

In the step ST400 of completing the stand 30 by entirely forging or cutting the raw material 20, the raw material 20 including the leg portions 33 and 34 is entirely forged or cut The final stand 30 can be completed by trimming or rounding the side portion of the body 31 or the overall shape of the leg portions 33 and 34.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. It will be apparent to those of ordinary skill in the art.
