Therefore, various equivalents And variations are possible.

Before describing the present invention with reference to the accompanying drawings, it should be noted that the present invention is not described or specifically described with respect to a known configuration that can be easily added by a person skilled in the art, Let the sound be revealed.

'의 형태를 갖도록 성형하는 장치에 관한 것으로, 구체적으로는 1회 가공으로 상기 2개면을 동시에 가공할 수 있도록 하는, 패널단부의 2개면을 성형하는 장치에 관한 것이다.In the present invention, two surfaces, i.e., an upper surface and a lower surface,

The present invention relates to an apparatus for molding two surfaces of a panel end so that the two surfaces can be simultaneously processed by one-time processing.

Hereinafter, the present invention will be described with reference to the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 schematically shows a configuration of an apparatus for molding two sides of a panel end according to the present invention. Fig.

The present invention according to Fig. 1 of the accompanying drawings mainly includes a panel support 10, a panel 20, a start plate 30, a fixing portion 40, and a cutting machine 50. Fig.

First, the panel support 10 is formed at the bottom in the present invention and serves to support the panel 20 as an object to be molded.

As shown in FIG. 1, the panel support 10 may have four corners and may have a hollow interior. However, the panel support 10 need not always have a hollow shape, and a space enough to support the support plate 11 It is natural that the inside of the panel support 10 may not be empty instead of forming the support plate 10 on the upper surface of the panel support 10. [

'의 형태를 갖는 다수의 돌기가 돌출되도록 할 수 있다. 이러한 돌기는 패널(20)과의 마찰력을 증진시켜 패널(20)이 밀리는 것을 방지하도록 한다. 한편, 상기 돌기의 상면에 미세 돌기들을 더 포함하도록 구성할 수도 있다.1, the support plate 11 is formed on one side of the panel support 10 to support the panel 20, and may be formed in a simple plate form as shown in the right side of FIG. 1, Likewise,

A plurality of protrusions having a shape of '' can be protruded. These projections increase the frictional force with the panel 20 and prevent the panel 20 from being pushed. On the other hand, the protrusions may be further configured to include fine protrusions on the upper surface thereof.

According to the design conditions, the support plate 11 may be configured to have a slide groove on the inner surface of the panel support 10, rather than being simply fixed to the panel support 10, By further including a roller wheel, the position of the support plate 11 can be set variously.

At this time, the roller wheels may be formed on the upper and lower sides of the support plate 11, that is, two on both ends, and the roller wheels may move along the upper surface and the lower surface of the slide groove of the panel support 10 .

To this end, the height of the slide groove should be the same as the height of the support plate 11, so that the support plate 11 should be easily fixed.

Accordingly, the support plate 11 may be positioned horizontally with respect to the width direction of the panel support 10 as shown in FIG. 1, but may be inclined with respect to the width direction. Thereby, there is an advantage that the supporting force can be increased even when the panel 20 is not a rectangular plate but a trapezoid or the like having different lengths on each surface.

However, a stopper may be provided on one side of the roller wheel to increase the fixing force of the roller wheel, and the movement of the roller wheel can be controlled by the stopper. At this time, since the conventional relation between the roller wheel and the stopper is used, a detailed description thereof will be omitted.

The panel 20 is an iron plate to be molded and placed on the upper side of the support plate 11 of the panel support table 10.

The start plate 30 is mounted on the panel support base 10 in the same manner as the panel 20 and can be installed on the panel 20 near the start of the forming of the panel 20.

More specifically, one or more joint portions 31 are connected to the joint portion 31. The joint portion 31 is formed in a pair of plate shapes extending from the upper surface and the lower surface of the start plate 30 in the direction of the panel 20.

The connecting portion 31 and the panel 20 are connected to each other through the fixing portion 40 so that the starting plate 30 can be fixed near the starting point of the panel 20.

Thus, the start plate 30 allows a part of the cutting machine 50, which will be described later, to be positioned before the start of molding.

The reason why the start plate 30 is necessary is that the start can be formed from one end near the start when the panel 20 is first to be molded and if the start plate 30 is not provided, When the panel 20 is molded by using the panel 20, it is molded from the middle portion of the panel 20, and molding from the end near the start is impossible.

As shown in Fig. 1, the fixing portion 40 is configured to be able to fix the fixing object by pressing it in the upward and downward directions. When the adjusting means (bolt or the like) provided on one side is operated, It is sufficient if the height is configured to be adjusted.

That is, the pressing region of the fixing portion 40 in the upward and downward directions pushes the joining portion 31 of the starting plate 30 inserted into the panel 20, 20).

'의 형태를 갖도록 절삭 성형하는 기계로서, 시작판(30)에서부터 패널(20)까지의 상면에서 이동할 수 있도록 구성된다.The cutting machine 50 is configured such that the forming cross-section of the panel 20 is '>'

And is configured to move from the start plate 30 to the panel 20 on the upper surface.

Specifically, reference is made to Figures 2 and 3 of the accompanying drawings.

Fig. 2 schematically shows the configuration of a cutting machine in an apparatus for forming two sides of a panel end according to the present invention, and Fig. 3 is an enlarged view of the square area of Fig.

According to Fig. 2 of the accompanying drawings, the cutting machine 50 is constituted as follows.

The body 51 serves as a basic base of the cutting machine 50. Such a structure may include a configuration for discharging a source (cutting flame) for oxygen cutting using a source for oxygen cutting supplied from the outside, a gear configuration for feeding and a deceleration configuration, Since many of them are disclosed, a detailed explanation is omitted.

The speed adjusting unit 52 is configured on the upper surface of the body 51 and is configured to adjust the reduction gear configuration in the body 51 by rotating.

That is, the user can accelerate / decelerate the moving speed of the cutting machine 50 by operating the speed adjusting portion 52. [

The front wheel 53 is formed on the front side of the body 51 (in the direction opposite to the start plate), and is shown as being one in front of the body 51 in FIG. 2, .

The rear wheel 54 is formed on the rear side (start plate direction) of the body 51 so that the body 51 can move together with the front wheel 53. [

The guide 55 is provided at one side of the body 51 and functions to guide the cutting machine 50 to move along the longitudinal direction of the panel 20. [

The guide 55 includes a body connecting plate 55a connected to the body 51 by screws or bolts and a horizontal connecting portion 55b connected to the body connecting plate 55a and extending to a side of the panel 20 A vertical connection part 55c vertically connected to one end of the horizontal connection part 55b and a roller 55d connected to the bottom of the vertical connection part 55c by an axis.

That is, the roller 55d is configured to move along the longitudinal direction of the panel 20 when the cutting machine 50 moves, by being rotated against the side surface of the panel 20.

1 shows that the panel 20 has a lengthwise direction in the lengthwise direction of the panel 20 but the cutting machine 50 can be moved in the longitudinal direction of the panel 20 according to the configuration of the guide 55 even if the panel 20 is bent It has a remarkable effect that it can move along.

Meanwhile, the horizontal connection portion 55b may be formed in multiple stages by an antenna method so that the length can be adjusted.

This allows the cutting machine 50 to flexibly move along the curved side surface of the panel 20 when the panel 20 has a curved shape by freely adjusting the length of the horizontal connection portion 55b have.

A cover made of a flexible material may be provided on the outer periphery of the roller 55d so as to move along the curved side surface of the panel 20 more flexibly.

The base 56 is formed on one side of the upper portion of the body 51 and serves to connect the structures described below for cutting.

The base 56 may have a plurality of transverse adjustment grooves 56a spaced at predetermined intervals.

The cutting source supply unit 57 is provided at one side of the base 56 and functions to receive a source for oxygen cutting from the outside. In this case, since the definition of the cutting source uses a commonly used oxygen cutting, it can be easily understood by a person skilled in the art, and a detailed description thereof will be omitted.

The cutting portion 58 serves to cut off the panel 20 by emitting a cutting flame for oxygen cutting. As shown in Fig. 2, the two cutting portions 58 are configured to face each other in a pair.

This is because, as described above, it is possible to adjust the width, height, and angle depending on the shape of the cutting cross section as a configuration for machining the end to be cut of the panel 20 at one time.

Specifically, referring to FIG. 3,

The cutting portion 58 includes a base fixing portion 58a connected to and fixed to the base 56. The base fixing portion 58a is configured to surround the outer circumference of the base 56, And the connecting portion 58b is protruded. That is, a total of two connecting portions 58b are included as one end of the base fixing portion 58a is broken. Grooves (not shown) are formed in each of the connecting portions 58b, and each connecting portion 58b So that they are in surface contact with each other.

Although not shown in the drawing, a screw or a bolt such as a butterfly bolt may be inserted into the groove to connect the connection portion 58b, so that the base fixing portion 58a can be fixed to the base 56. [

At one side of the base fixing portion 58a, a lateral direction adjusting portion 58c is formed in a hole shape, and a lateral direction adjusting bolt 58d is inserted into the lateral direction adjusting portion 58c.

A pinion is formed at one end of the transverse adjustment bolt 58b inserted in the transverse adjustment portion 58c and the transverse adjustment groove 56a functions as a rack, (56).

That is, as described above, since the number of the cutting portions 58 is two, the mutual width can be adjusted.

The vertical adjustment guide 58e is formed in the other side of the base fixing portion 58a in the form of a hole and the vertical adjustment guide 58e is provided with a vertical adjustment groove 58g, 58f are inserted.

A longitudinal direction adjusting portion 58h having a direction perpendicular to the longitudinal direction adjusting guide 58e is formed at one side of the longitudinal direction adjusting guide 58e, and the longitudinal direction adjusting bolt 58i can be inserted into the hole.

Likewise, a pinion is formed at one end inserted into the longitudinal direction adjusting portion 58h of the longitudinal direction adjusting bolt 58i, and the pinion abuts against the longitudinal direction adjusting groove 58g, and the longitudinal direction adjusting groove 58g So that the longitudinal direction adjusting rods 58f can be operated in the upward and downward directions according to the operation of the longitudinal direction adjusting bolts 58i, thereby making it possible to adjust the height of the cutting portions 58. [

The rotation connecting portion 58j is connected to the lower direction of the longitudinal direction adjusting rods 58f. The rotating connecting portion 58j is formed with an emitting portion shaft (not shown) And is rotatable in the outer circumferential direction of the connecting portion 58j.

And a cutting source emitting portion 58k may be connected to the emitting portion shaft. Accordingly, the cutting source emitting portion 58k is rotatable along the emitting portion axis, so that the angle of the cutting portion 58 can be adjusted.

However, as described above, two cutting portions 58 are formed, and the cutting source emitting portions 58k of one and the other cutting portion 58 are mutually opposed with respect to the rotational connecting portion 58j Respectively.

Therefore, in the present invention as shown in the drawing, the cutting source emitting portion 58k of the cutting portion 58 positioned on the outer side starts to mold the end portion of the panel 20 first, The discharge portion 58k starts to mold the end portion of the panel 20 at another angle.

With the configuration as described above, the molded panel 20 has a molded end as shown in Fig. 4 (see the bottom of the arrow in Fig. 4).

Fig. 4 is a sectional view showing an example of forming two sides of a panel by an apparatus for molding two sides of a panel end according to the present invention. Fig.

It is obvious that the present invention is not limited to the above-described description, as it is possible to design variously within the technical scope of the present invention.
