Abstract

PURPOSE: To improve design of the surface of a metal siding by applying a treatment having a three-dimensional effect to a decorative surface of the metal siding without increasing production cost. CONSTITUTION: In a manufacturing device for a metal siding comprising a delivery part 4 consisting of an uncoiler 1 and a pinch roller 2, a forming roll part 5 which can form a thin metal plate 3 into a shape so that left and right ends thereof can be engaged with each other in the longitudinal direction, an injection head 7 for feeding raw liquid of plastic foam 6 which will become a core material, and a delivery part 9 of a rear side material 8, a press processing device 10 is disposed between the delivery part 4 and the roll part 5. A die blanking processing is applied to the plate 3 at regular intervals to form notches, and further a press processing device 12 is installed between the roll poart 5 and the head 7. And a vertical joint having inverted U-shape is formed at each notch.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to metal siding and a method for manufacturing the same.

[0002]

2. Description of the Related Art Conventional metal siding has a strong image of being inexpensive, and since a flat metal plate does not give a high-class feeling, it is stucco-like or brick-like in order to improve its design. Squeeze with the embossing roll of the pattern, or apply a stone-tone special coating to the metal plate,
As an accent, processing such as forming ribs in the longitudinal direction with foaming crawling is the mainstream. However, if the material used for embossing is also thick, the drawing depth cannot be sufficiently obtained, and even if special coating is applied, the surface does not have a three-dimensional effect, and it is beyond the range of fake products. In addition, even if ribs are inserted, there is almost no change because it is the same as the joint direction of siding. With conventional continuous metal siding production methods, it is difficult to manufacture products with a uniform cross section, so the above-mentioned degree of processing is the best, and a wall surface that creates a three-dimensional three-dimensional effect such as masonry, tiles, and bricks. Was impossible to produce. If a method of molding and injecting one by one is used instead of the continuous production method, it is possible to manufacture a product having a free shape to some extent, but this method causes an increase in cost.

[0003]

The problem to be solved by the present invention is to improve the surface design of metal siding by giving a three-dimensional processing to the decorative surface of metal siding without increasing the production cost. is there.

[0004]

[Means for Solving the Problems] In order to solve the above problems, the present invention makes it possible to make three-dimensional unevenness appear by adding press working while keeping the advantages of the conventional continuous production method. Is. That is, a press working device is arranged between the metal thin plate feeding part and the forming roll part, a shearing force is applied to both longitudinal ends of the unmolded metal thin plate, and die punching is performed at a constant interval. A cutout is provided, and a press machine is also installed between the forming roll section and the injection head section, and a metal mold is applied to the cutout to form an inverted U-shaped vertical joint perpendicular to the longitudinal direction of the thin metal plate. Formed.

EXAMPLE An example of claim 1 is shown in FIG. 1 and an example of construction is shown in FIG. The metal siding according to the present invention is a so-called horizontal type, and the surface decorative portion 14 made of the metal thin plate 3 is used.
A plastic foam 6 which is a core material and a back surface material 8 and which have fitting shapes capable of fitting with each other at both longitudinal ends, and have a vertical cross-section vertical shape on the surface decorative portion 14 at a predetermined pitch. It has joints 13. An embodiment of claim 2 is shown in FIG. The feeding portion 4 of the strip-shaped metal thin plate 3 including the uncoiler 1 and the pinch roller 2, the forming roll portion 5 that molds the left and right ends of the metal thin plate 3 into a shape that can be fitted in the longitudinal direction, and the self-adhesiveness that serves as the core material. In an apparatus for producing metal siding, which comprises an injection head part 7 for supplying a stock solution of the foamed plastic foam 6 to the metal thin plate 3 to be continuously molded and delivered, and a delivery part 9 for a backing material 8 to be laminated on the foamed plastic foam 6. Then, the press working device 10 is arranged between the metal thin plate feeding part 4 and the forming roll part 5, and a shearing force is applied to the length of the unmolded metal thin plate 3 to perform the die punching process at regular intervals (Fig. 3). ), The notch portion 11 is provided, and after the forming roll portion 5 is formed (FIG. 4), the notch portion 11 is subjected to mold forming using the press working device 12 and the metal thin plate 3 is formed. The credit U-shaped longitudinal joint 13 which is perpendicular to the longitudinal direction is formed (FIG. 5).

[0006]

[Effects of the Invention] By punching the left and right ends of a thin metal plate to make notches, and by making deep joints by pressing in the notches, a three-dimensional and profound feeling appears on the decorative surface of the metal siding, and the aesthetic appearance is improved. improves. In addition, since conventional continuous production is possible, there is no cost increase.
