Description

Metal panel forming and coating device using variable mold

The present invention relates to a metal panel forming apparatus, and more particularly, in a state in which the panel is fixed, side and corner forming is possible by variable operation. A manufacturer who coats the cut surface of the panel after manufacturing the panel in a hexahedral shape, a foam packing It relates to a metal panel forming coating device using a variable forming mold applied to automobile manufacturers and home appliance manufacturers that manufacture doors to form, and companies that manufacture doors of various cases.

In general, for mechanical devices, automobiles, various enclosures and opening/closing doors, metal panels for construction are interior and exterior materials for construction that are attached to the exterior or interior walls of buildings and are used for the purpose of protection and decoration of buildings. Such a metal panel for construction is manufactured to have a three-dimensional structure of a hexahedron with an open bottom by bending the upper, lower, left, and right sides of a square metal plate.

In particular, it can be processed by pressing the metal plate using a press forming mold. However, when a metal sheet is to be processed to have four corners, for example, when the radius of the four corners of the press forming mold is small, there is a problem in that the metal sheet is torn during the processing of the metal sheet.

In this way, in the case of manufacturing a door using a conventional metal plate as an example, after chamfering the four corners of the metal plate, the four parts are vertically bent to form a side part. Then, the four side parts are welded to connect the four side parts.

More specifically, in the case of manufacturing a door requiring a sealing function, after chamfering the four corners of the metal plate, the four parts are bent vertically to form a side part, and then the four side parts are welded to connect the four side parts.

And, after chamfering the boundary of the four side parts again, the outer door is manufactured by folding a part of the four side parts inward to form a flange part. According to this conventional processing method, since the four side portions of the sealing door are joined by welding, there is a problem in that the foaming agent leaks when there is a portion that is not welded.

In addition, since the operator has to weld the four side parts, a problem that takes a lot of time occurs when manufacturing the door.

Then, after chamfering the boundary of the four side parts again, the outside door is manufactured by folding a part of the four side parts inward to form a flange part. According to this conventional processing method, since the four side parts of the sealing door are joined by welding, , there is a problem that the foaming agent leaks if there is a part that is not welded. In addition, since the operator has to weld the four side parts, a problem that takes a lot of time occurs when manufacturing the door.

In the conventional method, in manufacturing a rectangular parallelepiped-shaped metal panel, in order to facilitate bending of each side, a portion of each corner of a square metal plate is cut and then bent, and the incised portion is bent on each side. After losing, separate caulking or welding is performed on the edge to close the gap at the edge caused by the cutout.

However, since the metal panel manufactured by the process according to the conventional method as described above has poor watertightness and is accompanied by deformation of material, shape, or physical properties by heat generated during welding, mechanical strength or corrosion easily occurs. there was.

In consideration of the manufacturing disadvantages of the conventional metal panel as described above, in recent years, without cutting the corners of the square metal plate, pre-bending so that unbent portions remain at the end of each side of the square metal plate, and then pressing the edge using a forming roller this is being used

According to this improved method, there is an advantage in that a corner is formed in which two adjacent sides of a square metal plate are connected naturally without a gap, and a metal panel with an integrated structure without a gap is produced by cutting the part stretched by the pressure of the forming roller . A process diagram of manufacturing a metal panel without a gap is shown in FIG. 1 .

2 is a perspective view showing a structure of a forming roller for forming a corner of a conventional metal panel.

In the conventional structure of a forming roller for forming a corner of a metal panel, the forming roller 2 is installed so that both ends are supported by a bearing 3 so that it can rotate, and when forming the corner of the metal panel 1, the forming roller (2) is configured to form a corner of the metal panel by pressing the metal panel 1 while moving in a vertical direction from top to bottom.

However, the forming roller having the above structure can smoothly form a plate of a relatively soft material such as aluminum, but when forming a plate of a relatively strong material such as a galvanized steel sheet, a gap between the forming roller and the bearing supporting it Due to the play, the forming roller was pushed slightly, and the edge of the metal panel could not be bent to form a perfect right angle, so there was a problem in that the product was defective.

And, Figure 3 is for processing the corner curvature forming of the conventional metal panel, and in order to perform the conventional corner forming operation of the metal panel, the operator bends the panel at four corners. There was an uncomfortable problem that had to be done.

In addition, when the size of the panel is large in order to perform the conventional corner forming operation of the metal panel, there is an inconvenient constraint that two or more workers must perform the operation together.

Due to this, the forming frame is adjusted to the size of the panel according to the size of the panel for corner forming, and the side forming and corner forming are performed simultaneously to simplify the process and work with panels of various sizes in one forming forming frame. There is an urgent need for an improved metal panel forming device to increase the utilization of the panel and to coat it in an automated manner so that no safety accident occurs at the end of the panel cutting.
