Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention provides an uneven pattern on a part or the whole surface of a thin metal sheet material, slits in an n-series, and continuously cuts each thin metal sheet material. The present invention relates to a metal thin plate material forming roll device which is useful for forming concave portions in respective cross sections and for forming an uneven pattern at arbitrary positions on its decorative surface portion.

[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 the uneven patterns are easily contacted with each other to cause scratches. Added,
Furthermore, since tension is applied during rewinding in the molding process,
There is a defect that twisting, warping, pebbles, 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. , Move, etc.
Not only is there considerable waste and inefficiency until it becomes a product, but there has not been an apparatus for manufacturing products of n sheets, for example, two sheets at the same time, or different double embossed patterns and shapes.

[Means for solving problems]

In order to eliminate such drawbacks, the present invention arranges an embossing roll, a slit roll, a forming roll group, and a streak-like embossing roll that forms a streak-like ripple pattern in this kind of forming roll device, and slits a thin metal plate material. In addition, by molding in n series, for example, 2 series, and forming a concavo-convex pattern on the whole or a part of the decorative surface of each thin metal sheet material, it has a beautiful appearance without distortion, and a thin metal sheet with an arbitrary pattern in an arbitrary cross section. The present invention proposes a metal thin plate material forming roll device capable of producing a roll-formed product having a plate material having the above-described shape and the like all at once from a commercially available coil width.

〔Example〕

Hereinafter, an embodiment of a thin metal sheet forming roll device (hereinafter, simply referred to as a roll device) according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing the outline of the above-mentioned apparatus, and FIG. 2 is an explanatory view showing the steps separately.
In the figure, 1 is a guide portion, 5 is an embossing roll, 6 is a slit roll, 7 is a forming roll group, 8 is a streak embossing roll, 9 is a frame, 10 is a stand, and all of them are mounted on the same frame 9. To do. The rolls in each process may be replaced in a unit type. To further explain, the guide portion 1 is the entrance of the roll device, is at the same height as the pass line of the roll group, and is horizontally and flatly placed on the mounting plate 2 and the metal thin plate material A at the front end of the mounting plate 2. Of the elastic guide plate 3 (hereinafter simply referred to as a guide plate) 3 fixed in a V shape with a width corresponding to the width W ₀ of the front and a guide arranged and supported at the same width as the above just before the entrance of the roll group. It is composed of a roller 4 and mainly serves to accurately guide the thin metal plate material A to the roll group. Further, the distance P between the guide plate 3 and the guide roller 4 is 50-
It is about 500 mm. The emboss roll 5 is an upper roll 5
The metal thin plate material A is made of a and 5b and is provided with an arbitrary uneven pattern on the whole surface or a part thereof. Also, the slit roll 6
Is arranged in the next stage of the embossing roll, and is formed by upper and lower blades 6a and 6b which divides the central portion of the metal thin plate material A into n as shown in FIG. Of course, W ₀ / 3~W ₀ 15
It is also possible to divide into arbitrary widths, one of which is a material for a thin metal plate material, and the rest of which is cut for an accessory. Further, the forming roll group 7 is formed by forming the thin metal plate material A slit into a predetermined size with a plurality of stages of n series, as shown in FIGS. The rolls 7a, 7a ', 7b, 7b', 7c, 7c '... 7n, 7n' are constructed. The streak-shaped embossing roll 8 has male and female upper and lower rolls 8a and 8b installed at the substantially final stage, and the decorative surface A ″ of the formed metal sheet A is required to have, for example, the fifth
As shown in the figure, convex ribs are formed.

Next, the operation of the roll device according to the present invention will be described.
Now, assume that each roll on the frame 9 is driven by a motor (not shown) via a chain (not shown), and the diameter and the number of rotations are selected so that the pass lines have the same peripheral speed. I assume. The striped embossing roll 8 is the fifth
It is a rib-like pattern with a depth of 0.5 mm shown in the figure. The thin metal plate A is a 0.27 mm thick color steel plate with a total width W ₀ = 500 m.
prepared m. In addition, as the roll, nylon resin having a thickness of 0.5 mm and a density of 1.0 g / cm ³ was coated on all of the rolls. Then, a color steel plate A having a flat cross section and a length of 3636 mm is fed onto the placing plate 2 of the guide portion 1 , and on the placing plate 2, the guide plate 3 and the guide roller 4 move horizontally straightly and are embossed. It is fed to roll 5 , where the entire surface of thin metal sheet material A is provided with an uneven pattern, and then slit roll
Delivered to 6 . As shown in FIG. 3, the slit roll 6 is divided into two parts, which are fed to the forming roll group 7 as shown in FIG.
The thin metal plate material A is molded in two series on the cross section shown in
The intermediate molding body A ′ is used. Next, a convex rib as shown in Fig. 5 is formed at the final stage on the decorative surface A "of this molding intermediate body A ', and it is sent to the next step as a molded product. It is also possible to use the thin metal plate material A. Furthermore, as shown by the alternate long and short dash line in Fig. 1 , a preheater may be installed in front of the guide portion 1 to protect the coating film.

〔The invention's effect〕

As described above, according to the roll device of the present invention, a coil-shaped, wide-width metal thin plate material is embossed with a concavo-convex pattern by a single molding machine, then slit, and molded into an n-series cross-sectional shape, It is characterized in that it is possible to manufacture a thin metal plate product in which a streaky uneven pattern is applied to any part of the decorative surface at the final stage. In addition, since embossing, slitting, molding, and streak embossing can be performed in one unit and in a plurality of series, it is possible to simultaneously manufacture deformed products at low cost. Furthermore, if the embossing roll, slit roll, forming roll group, and embossing roll are unit type, there is a feature that various types of molded products can be easily manufactured.
