As shown, the bending machine according to the present invention relates to a technique for processing the edge 110 of the metal plate 100 used in various fields, such as electronic products into various shapes as needed.

In particular, when the edge 110 of the metal plate 100 is to be processed into a predetermined curved surface, the shape of the curved surface may be variously processed as necessary.

As shown in FIG. 1A, when using the bending machine according to the present invention, the rectangular metal plate 100 may be bent to the edge of the metal plate 100 as desired.

Hereinafter, an apparatus and a method for processing the edge of the metal plate 100 as shown in FIG. 1 as B will be described in detail.

As shown, Figure 2 is a view showing the basic structure of the bending machine according to the present invention.

The bending machine according to the present invention includes a linear roller 300 for bending an edge by pressing the lower structure 200 supporting the metal plate 100 to be processed and the metal plate 100.

The lower structure 200 may be configured in various forms according to the processing method of the metal plate 100. For example, when both edges of the metal plate 100 are bent at the same time as shown in FIG. 2, the same structure is symmetrical.

If only one edge of the metal plate 100 is to be processed, the lower structure may be configured of only one structure of FIG. 2, and the other structure may be simply configured to support the metal plate 100.

The undercarriage 200 includes a bending head 210, a support shaft 220, and a support plate 230.

The bending head 210 is located on the metal plate 100 to determine the actual machining shape of the edge of the metal plate 100.

Therefore, the bending head 210 may be configured in various forms as necessary. If the edge of the metal plate 100 is to be processed in the form of a perfect circle and to be configured in the form of an ellipse, the shape of the bending head 210 may be varied.

The bending head 210 according to FIG. 2 shows an example in which an edge of the metal plate 100 may have a curved surface in the form of an ellipse. However, the bending head 210 of the present invention is not limited thereto and may be variously modified as necessary.

The support shaft 220 connects the bending head 210 and the support plate 230. The support shaft 220 may be configured in the form of a plate as well as a pillar. The support plate 230 serves as a support for the undercarriage 200.

In order to process the metal plate 100 to a desired curved surface, the linear roller 300 presses the metal plate 100 along the bending head 210. At this time, the linear roller 300 presses the metal plate 100 while moving in the direction of the arrow.

The linear roller 300 may rotate about both axes to press the metal plate 100 while moving along the bending head 210.

An upper structure (not shown) for transporting and supporting the linear roller 300 controls the movement of the linear roller 300.

Fig. 3 shows a second embodiment of a bending machine capable of sequentially processing a metal plate according to the present invention, and Fig. 4 is a perspective view showing a specific embodiment of the bending machine according to the present invention.

As shown, Figures 3 and 4 show the bending machine for processing the metal plate sequentially in accordance with the processing form of the edge in the processing of the edge of the metal plate 100.

First, the bending machine according to the second embodiment is a straight line for pressing the metal plate 100 and the substructure 200 including the bending head 210, the support shaft 220 and the support plate 230, as shown in FIG. A fixing plate 400 including an upper structure 600 supporting the roller 300 and the linear roller 300, and additionally, pressing and fixing the metal plate 100 with a constant force to prevent vibration and shaking of the metal plate 100. ) Is connected to the superstructure 600.

In addition, the transfer body 530 for controlling the transfer arm 520 and the transfer arm 520 to transfer the first processing plate 510, the first processing plate 510 up and down primarily to machine the edge of the metal plate 100. ).

Specifically, first, the metal plate 100 is moved by a moving means (not shown), and positioned above the first processing plate 510 and the bending head 210.

The first processing plate 510 is located outside the bending head 210 and the support shaft 220 of the substructure 200, and controls the transfer arm 520 to move the first processing plate 510 up and down. The main body 530 may be positioned on the support plate 230 of the substructure 200.

After the metal plate 100 moves to the required position by the moving means, the fixed plate 400 connected to the upper structure 600 descends and presses the metal plate 100 to fix the metal plate 100 so as not to move.

After the metal plate 100 is positioned on the first processing plate 510 and the substructure 200, and the metal plate 100 is fixed by the fixing plate 400, the transfer body 530 controls the transfer arm 520. The first processing plate 510 is moved upward to be positioned on the bottom surface of the metal plate 100. It is preferable that the first processing plate 510 is in contact with the lower surface of the metal plate 100.

After the first processing plate 510 moves, the linear roller 300 connected to the upper structure 600 presses the metal plate first along the first processing plate 510.

In this case, the edge of the metal plate 100 may be processed in various forms according to the structure of the first processing plate 510. 3 shows an example in which the first processing plate 510 is formed in the form of a right angle plate, and the edge of the metal plate 100 is formed at a right angle.

After the edge of the metal plate 100 is primarily processed by the first processing plate 510, the first processing plate 510 is lowered to its original position.

In addition, the linear roller 300 moves to the upper portion of the bending head 210 for the secondary processing by the bending head 210. Therefore, the linear roller 300 moves to a predetermined position according to the control signal.

When the linear roller 300 is positioned above the bending head 210, the linear roller 300 presses the metal plate 100 along the bending head 210 to perform secondary processing.

Secondary processing may be variously processed according to the shape of the bending head 210. 3 shows an example in which the metal plate 100 is bent in the form of an ellipse.

Therefore, after the primary processing and the secondary processing are performed, the metal plate 100 is processed in the form of an ellipse by the secondary processing after being processed at a right angle by the primary processing.

After the secondary processing is completed, the fixed plate 400 is moved upward, and the metal plate 100 is moved by a moving means (not shown).

It is a figure which shows the method of processing a metal plate using the bending machine which concerns on this invention.

In the metal plate processing method using a bending machine, the metal plate is moved by a moving means, and then the fixed plate is lowered to apply a predetermined pressure to the metal plate to fix the metal plate.

After the metal plate is fixed by the fixing plate, the first plate is moved upward so as to be in contact with the bottom surface of the metal plate. (S520) The first plate is to be processed primarily when the metal plate is sequentially processed. Is made of.

When the first working plate is located on the lower surface of the metal plate, the linear roller is moved along the first working plate while pressing the metal plate to perform the primary processing.

After the metal plate is first processed by the linear roller, the first processed plate is returned to its original position, and the linear roller is moved to the upper portion of the bending head for the secondary processing (S540).

When the linear roller is located above the bending head, the linear roller is moved along the bending head to pressurize the metal plate to perform secondary processing.

When the secondary machining is completed, the bending machine returns to its initial state. Therefore, the fixing plate holding the metal plate is separated from the metal plate, the linear roller returns to the initial position, and the metal plate is moved to the required position by the conveying means or the like (S560).

The present invention described above is capable of various substitutions, modifications, and changes without departing from the technical spirit of the present invention for those skilled in the art to which the present invention pertains. It is not limited by the drawings.
