DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a processing material used for a kamaboko-shaped roof and a curved wall.
A waveform with peaks parallel to the width direction is formed on either fully lined steel plate or partially lined steel plate, and the cross section perpendicular to the longitudinal direction is formed into a trough-like shape with a substantially trapezoidal shape. The present invention relates to a forming roller device for manufacturing a metal roof plate or wall plate or the like (hereinafter, simply referred to as a metal roof plate) whose waveform is curved in the longitudinal direction with a radius of curvature that does not hinder the flow of dust, rainwater, washing water, or the like. .

[0002]

2. Description of the Related Art A forming roller device continuously forms a large number of forming rollers composed of an upper roller and a lower roller which can be separated and adjusted by a manual separating mechanism made up of an eccentric cam and a lever in a feeding direction of the forming material. The forming material is sequentially deformed by these forming rollers so that a metal roofing plate having a substantially trapezoidal end surface can be finally formed.

[0003] The above apparatus is mainly used as an apparatus for forming a linearly inclined metal roof or a vertical metal wall, but in recent architectural designs, it is required to use a semi-cylindrical roof or a bulging curved wall. Therefore, it is impossible to form a curved shape having a required large radius of curvature after securing sufficient strength.

[0004] In order to meet the above demands, 1) Only the forming roller disposed at the end of the conventional forming roller device is provided with a gear-shaped or spline shaft having a shallow corrugated groove. As a roller in the shape, after forming sequentially into a trough shape with a substantially trapezoidal end face without forming a waveform on the forming material, a waveform is formed in which the peaks are parallel to the width direction, and under the flow of dust, rainwater, washing water, etc. Means for forming a curve in the longitudinal direction with a radius of curvature that does not cause a problem; 2) forming the forming roller of the conventional forming roller device into a shallow waveform for forming a waveform in which the peaks are parallel to the width direction of the forming material. Using a device that is a roller with a gear-shaped or spline-shaft cross-section with uneven grooves formed, the forming material has flat peaks in the width direction over its entire width. Waveform sequentially molded into the end face substantially trapezoidal trough while forming the, and dust, rainwater, means for bending formed in the longitudinal direction on the order of a radius of curvature that trouble does not occur in the stream of such wash water,
The company manufactures metal shingles for the formation of Kamaboko roofs.

[0005]

However, in the means of 1), a waveform is formed on the gutter-shaped bottom, but no waveform is formed on the gutter-shaped side wall, so that the strength of the side wall portion cannot be secured. Despite the formation of the corrugations, there is the disadvantage of having to use a material of the same thickness as conventional ones, and since the corrugations are formed all at once by the forming roller disposed at the end, a large machine It adds a mechanical load and lowers durability, and since a gutter-like bottom is formed with a waveform but not formed on the side wall,
Since the dimensional difference in the length direction is large, the radius of curvature of the curvature is small, and not only is its use limited, but also the overall distortion is large, and the gutter-like opening is uneven, so that roofing, There is a problem to be solved in terms of deteriorating the workability of wall covering.

In the method 2), the forming material is sequentially formed into a trough shape having a substantially trapezoidal end face while forming a waveform over the entire width of the forming material. Although the corrugation is formed and the strength is secured, the bent portion that becomes the boundary between the gutter-shaped bottom and the side wall is not formed by the waveform being crushed at the time of the bending process. And it is difficult to maintain the deformed state even if it can be deformed in a predetermined radius of curvature along the longitudinal direction, and even if it can be deformed, the metal roofing sheet is easily twisted in the longitudinal direction, and the end surface is substantially trapezoidal. Metal roofing plates fixed to the roof receiving frame or wall frame or the roofing that connects the wallboards to each other, resulting in a significant decrease in work efficiency such as wall covering, etc. To a point There was a problem to be determined.

According to the present invention, not only is the gutter-shaped bottom plate formed on both the gutter-shaped bottom plate and the side plates on both sides thereof with a waveform in which the peaks are parallel in the width direction to form a trough-like shape having a substantially trapezoidal end face, but also the folding of the side plate with respect to the gutter-shaped bottom plate. Ensuring bending upright strength, preventing torsion and shape collapse, and as a whole, accurately deforming the waveform of the gutter-shaped bottom in the longitudinal direction with a radius of curvature that does not hinder the flow of dust, rainwater, washing water, etc. Forming that can be used efficiently for work such as Kamaboko roofing, curved wall covering, etc., and can be used without any distinction as a steel plate material, a fully lined steel plate material or a partially lined steel plate material It is an object to provide a roller device.
