According to such a configuration, the concave and convex portions can be formed on the metal plate 1 while the concave and convex surface 2 for forming the concave and convex portions can be formed deeply by the multi-stage forming rolls 6a, 6b. When the concave / convex surface 2 to be rolled is formed, both flat ends of the metal plate 1 are pressed from above and below by endless belt- like pressers 5a and 5a , and the concave / convex surface 2 is rolled in multiple stages. Compared to means of pressing with a hard metal roll by pressing with endless rubber-like pressers 5a, 5a while preventing deformation due to stress on both ends of the metal plate 1 when forming. It is possible to avoid scratching the surface of the plate 1 and not to impair the appearance.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below. FIG. 1 is an explanatory view of a method for forming a metal siding A according to the present invention, FIG. 2 (a) is a sectional view of the metal siding A, and FIG.
[0009]
As shown in FIG. 1, the metal plate 1 sent out by the uncoiler 7 is cut into an appropriate length by a cutting device 8, and the cut metal plate 1 is formed into multistage forming rolls 6a, 6b, 6c and 6d. Then, the concave and convex portions are formed deeply in order (for example, the forming depth is 3 mm, 4 mm, 5 mm, etc.), and the concave and convex surface 2 has, for example, a concave groove 9 formed on the metal siding A as shown in FIG. A plurality of concave strips 15 are formed with a gap in the width direction and a gap in the length direction. Forming convex portions 16 and forming concave portions 17 are formed on the upper and lower rolls of the forming roll 6a. Needless to say, the shape of the uneven surface 2 can be changed. After forming the concavo-convex surface 2, the end forming machine 14 forms a fitting projection 3 on one side end of the metal siding A in the width direction and a fitting recess 4 on the other end. Although the shape of the fitting convex part 3 and the fitting recessed part 4 is shown to Fig.2 (a), the shape can be changed. The end molding machine 14 may be a roll molding machine, but may be a press molding machine provided in the line.
[0010]
After the molding of the fitting convex portion 3 and the fitting concave portion 4, urethane resin is foam-filled as an example of the heat insulating material 10 on the inner surface of the metal plate 1, and the aluminum laminate film 11 is laminated on the back surface of the heat insulating material 10. To do. Thus, the metal siding A is manufactured. By the way, the deformation at the both ends 12 and 12 of the metal plate 1 is caused by the stress when the concave and convex portions are roll-formed on the metal plate 1 to form the uneven surface 2. Such deformation is avoided, so that the fitting convex portion 3 and the fitting concave portion 4 can be satisfactorily formed at both end portions 12 and 12.
[0011]
That is, as shown in FIG. 1 and FIG. 4, the flat end portions 12 and 12 of the metal plate 1 are vertically moved on both sides of the multi-stage forming rolls 6 a, 6 b, 6 c and 6 d for forming the uneven surface 2. Are provided with pressers 5a, 5a formed of rubber-like bodies in an endless belt shape sandwiched between the two. The endless belt-like presser 5 a is configured by attaching a rubber-like body 19 by a chain link 18.
[0012]
Thus, while the concave / convex surface 2 for forming the concave portion and the convex portion is formed on the metal plate 1, the end portions 12, 12 that are flat on the metal plate 1 are pressed from above and below the endless rubber-like body. 5a, 5a , and pressing with the rubber-like pressers 5a, 5a while preventing deformation of both ends due to stress on both ends of the metal plate 1 when the uneven surface 2 is roll-formed. Thus, it is possible to avoid scratching the surface of the metal plate 1 as compared with the means of pressing with a hard metal roll, and the appearance is not impaired.
[0013]
FIG. 5 shows another embodiment, in which a continuously fed metal plate 1 is continuously roll-formed to form an uneven surface 2, cut by a cutting device 8, and then an end forming machine. 14, the fitting convex part 3 and the fitting concave part 4 are shape | molded.
[0014]
【The invention's effect】
The metal siding according to claim 1, wherein the concave and convex portions are roll-formed on a metal plate to form an uneven surface, and then the fitting convex portion is roll-formed at one end and the fitting concave is roll-formed at the other end. The endless surface formed by a rubber-like body having elasticity on both ends of the metal plate while forming the uneven surface with a multi-stage forming roll and forming such an uneven surface. Because it is sandwiched from above and below by a belt-shaped presser , the concave and convex surfaces that form the concave and convex portions can be formed deeply with a multi-stage forming roll while forming the concave and convex surfaces to form the concave and convex portions. When the surface is roll-formed, both ends of the metal plate are pressed by the endless belt- like presser of the rubber-like body from above and below, resulting in stress transmitted to both ends of the metal plate. Prevents deformation It can, and, because pressed by the pressing of the endless belt-shaped rubber-like body, in comparison with the means for pressing in hard metal rolls can avoid scratching the surface of the metal plate, advantage of not disfiguring There is.
[0016]
The metal siding according to claim 2, wherein the concave and convex portions are roll-formed on the metal plate to form an uneven surface, and then the fitting convex portion is roll-formed at one end and the fitting concave is roll-formed at the other end. A multi-stage forming roll for forming an uneven surface, and while forming the uneven surface with such a multi-stage forming roll, both ends of the metal plate that are flat are moved up and down. Since it has an endless belt-shaped presser formed of a rubber-like body with elasticity to hold from, it can be formed deeply with a multi-stage forming roll to form concave and convex surfaces to form concave and convex portions. When the concave / convex surface for forming the concave and convex portions on the metal plate is roll-formed, the flat end portions of the metal plate are pressed from above and below by the endless belt- like presser of the rubber body. the metal plate in the case of roll forming a multistage While preventing deformation due to stress on the end portion, by pressing in pressing the endless belt-shaped rubber-like material, can avoid scratching the surface of the metal plate as compared to the means for pressing in hard metal rolls There is an advantage that the appearance is not impaired.
