【発明の詳細な説明】
本発明は、ビルの壁面仕上げ等に使用される壁面材の製
造方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing wall materials used for finishing walls of buildings.
この種壁面材として、例えば第1図に示すように、基体
lの周囲に側壁2を一体に備えた方形皿状のものが知ら
れている。このような壁面材は、従来、方形の金属板を
絞り加工することによって成形していたが、その加工に
当って次に列挙するような欠点があった。As this type of wall material, for example, as shown in FIG. 1, there is known a rectangular dish-shaped wall material having a side wall 2 integrally provided around a base 1. Conventionally, such wall materials have been formed by drawing a rectangular metal plate, but this process has the following drawbacks.
a 角部の絞りが非常に困難で肉厚むらや強度紙ド等を
生じ易く、そのため安定した製品を得ることが難しい。a It is very difficult to squeeze the corners and tends to cause uneven wall thickness and paper strength, making it difficult to obtain a stable product.
b 側壁を深く絞るのが難しいため、側壁の高い壁面材
を得るのが困難である。b. Because it is difficult to draw the side walls deeply, it is difficult to obtain wall materials with high side walls.
C絞り部分に集中的に大きな力が作用して歪や傷が生じ
易く、予め表面加工した金属板を使用することができな
い。A large force acts intensively on the C drawing area, which tends to cause distortions and scratches, making it impossible to use a metal plate whose surface has been treated in advance.
d 型を使用する必要があるため、加]二装置市が大が
かりになり、しかもその型に合った特定寸法の製品しか
得ることができない。Because it is necessary to use a mold, the manufacturing process becomes large-scale, and it is only possible to obtain products with specific dimensions that match the mold.
本発明は、このような壁面材を、型による大がかりな絞

。In order to achieve such an object, the method of the present invention provides arc-shaped notches that curve toward the tip at the four corners of a rectangular metal plate, and also provides a portion of the metal plate located outside the notch at the corner of the metal plate. and a step of bending the edge of the metal plate on a fold line that is located slightly inside the line connecting the ends of adjacent cuts and whose length is approximately the same as the distance between the ends. and a step of bending the tongue pieces formed at the four corners of the metal plate along the compound cuts along arc-shaped fold lines connecting the ends of adjacent vertical and horizontal fold lines.
而して、本発明の方法によれば、次に列挙するような効
果を期待することができる。According to the method of the present invention, the following effects can be expected.
A、折曲加工が主体であって、大がかりな絞り加工を必
要としないため、加工が非常に容易で肉厚むらや強度低
下のない安定した製品を得ることができる。A. Since the bending process is the main process and no large-scale drawing process is required, the process is very easy and a stable product without uneven thickness or loss of strength can be obtained.
B、型やそれに伴う大規模な加工装置が不要である。B. No mold or large-scale processing equipment is required.
C2折曲部にそれほど大きな力が作用したり歪が発生し
たりすることがないため、予め表面加工を施した金属板
を使用しても損傷する虞れが少ない。Since a large force is not applied to the C2 bent portion and no distortion occurs, there is little risk of damage even if a metal plate whose surface has been previously treated is used.
D、型による加工寸法の制約がないため、任意;」法の
壁面材を得ることができる。D. Since there are no restrictions on processing dimensions due to molds, wall materials of any desired size can be obtained.
以F、本発明の方法を図面を参照しながら詳述する。Hereinafter, the method of the present invention will be explained in detail with reference to the drawings.
壁面材の製造に当っては、まず、鉄、アルミニウム、ス
テンレスなど任意の素材からなる方形状の金属板を用意
し、この金属板をプレス加工等により第2図に示すよう
に切断する。即ち、金属板lOの四隅に、尖端部11に
向かって湾曲する円弧状の切込み12を設けると共に、
該切込み12の外側に位置する金属板lOの角部13を
切除する。In manufacturing the wall material, first, a rectangular metal plate made of any material such as iron, aluminum, or stainless steel is prepared, and this metal plate is cut as shown in FIG. 2 by press working or the like. That is, arc-shaped cuts 12 are provided at the four corners of the metal plate IO, and the cuts 12 are curved toward the tip 11.
The corner portion 13 of the metal plate IO located outside the notch 12 is cut off.
]二配合属板10には、予めメッキや塗装、ビニールコ
ーティングなどの表面加工を施しておいてもよい。] The two-component metal plate 10 may be previously subjected to a surface treatment such as plating, painting, or vinyl coating.
次に、上記金属板10の端縁を、隣接する切込み12.
12の端部12a、12bを結ぶ線より若干内側に位置
し且つ長さが上記端部12a、12b間の距離と略同長
の折線14上において直角に折曲し、それによって第3
図に示すように側壁15を形成する。この折曲作業はベ
ンダー等の機械を使用して行うことができ、折曲後の金
属板10においぞは、その四隅に切込み12に沿って形
成された円弧状の舌片16が非折曲状態のまま保持され
ることになる。Next, the edge of the metal plate 10 is cut into adjacent notches 12.
12 at a right angle on a fold line 14 that is located slightly inside the line connecting the ends 12a and 12b and whose length is approximately the same as the distance between the ends 12a and 12b.
A side wall 15 is formed as shown in the figure. This bending work can be performed using a machine such as a bender, and the grooves on the metal plate 10 after bending are such that the arcuate tongue pieces 16 formed along the notches 12 at the four corners are not bent. It will remain in its current state.
続いて、上記舌片16を、隣接する上記縦横の折線14
.1’4の端部同士を結ぶ円弧状の折線17に沿って側
壁15と同じ方向に折曲し、これによって第4図に示す

を吸収できてその加工を容易に行うことができ、特に、
このように切欠き18を設ける方法は、側壁15を高く
することによって舌片I6の絞り率が太きくなった場合
に有効である。Next, the tongue piece 16 is attached to the adjacent vertical and horizontal fold lines 14.
.. It is bent in the same direction as the side wall 15 along the arc-shaped folding line 17 connecting the ends of the 1' 4, thereby finishing the corner as shown in FIG. The bending of this tongue IB is
This can be done by a simple drawing process.At this time, if an appropriate number of notches 18 are cut in the edge of the tongue lB as shown by chain lines in FIG. It can absorb the shrinkage of edges and can be easily processed, especially
The method of providing the notch 18 in this way is effective when the drawing ratio of the tongue piece I6 becomes thicker by increasing the height of the side wall 15.
上記舌片】8の折曲が完了すると、側壁15の先端を外
側に向けて直角に折曲し、フランジ部18を形成する。When the bending of the tongue piece [8] is completed, the tip of the side wall 15 is bent outward at a right angle to form a flange portion 18.
このフランジ部18は必要に応じて設ければよく、また
、その折曲は、」配合側壁15の折曲と同時に行うこと
もできる。This flange portion 18 may be provided as necessary, and its bending can be performed simultaneously with the bending of the blending side wall 15.
