Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is to apply a concavo-convex pattern to a part or the whole surface of a thin metal plate material, correct the distortion with a group of leveler rolls, and then emboss this. N thin metal sheet material with slit roll
An n-series forming roll group that divides and divides each divided plate material into an arbitrary cross-sectional shape, and a streak-shaped embossing roll that applies streak-shaped embossing at an arbitrary position on the decorative surface portion of the formed thin metal plate material. The present invention relates to a metal thin plate material forming roll device useful for providing an uneven pattern at an arbitrary position.

[Conventional technology]

Generally, in building materials using surface-treated steel sheets, thin metal sheets such as aluminum sheets, many attempts have been made to improve the bad image of a smooth, cold metal by giving an uneven pattern to the decorative surface. There is. As the manufacturing device, any device such as a device for performing embossing on the entire metal hoop material and then forming it into a predetermined shape, or a device for simply forming it into a predetermined shape after embossing the necessary part Is manufactured by.

[Problems to be solved by the invention]

However, in the former device, the coil diameter is significantly increased, the number of windings is reduced, and moreover, the uneven patterns are likely to come into contact with each other and are easily scratched.
Further, since tension is applied during rewinding in the molding process, there is a drawback that twisting, warping, peking etc. occur after molding. In the latter case, the embossing is applied only to a certain area of the central part of the metal hoop material, and the embossing is applied to the molding machine in that state, so that there is a disadvantage that the boundary of the decorative surface and the uneven pattern “shift”. It was It is because the both edges of the embossed metal hoop material become wavy due to residual stress, and even if it is fed to the molding machine using this as a guide, the edge of the uneven pattern matches the edge of the predetermined range of the decorative surface Because not. Further, in the past, in order to form a metal hoop material into a predetermined cross section, a coil of 914 mm, 1000 mm, etc. was cut into a predetermined development dimension with a slit line, and this was fed to an embossing line and a forming line. In addition to being very wasteful and inefficient until it becomes a product such as movement, there was no apparatus for simultaneously manufacturing n, for example, two, or products with different double embossing patterns and shapes.

[Means for solving problems]

The present invention, in order to eliminate such defects, the embossing roll, leveler roll group, slit roll, forming roll group, streak-like embossing roll forming a streaky ripple pattern in this kind of forming roll device are arranged in this order, and Along with slitting the thin plate material, forming it in n series, for example, 2 series, and forming a concavo-convex pattern on the whole or part of the decorative surface of each metal thin plate material, it has a beautiful appearance without distortion, and it is optional in any cross section The present invention proposes a metal thin plate forming roll device capable of producing a roll formed product having a patterned metal thin plate material having the above-mentioned shape and the like all at once from a commercially available coil width.
