Abstract

PURPOSE:To reduce a production cost by forming the engagement part of the final shape in V-shaped or reverse V-shaped cross-section on a plate by the roll forming at the initial stage and forming in order the remaining part by the roll forming at the middle and final stages. CONSTITUTION:The engagement part P3 of V-shaped or reverse V-shaped cross- section consisting of an orthogonal piece P3a and inclined piece P3b is subjected to roll forming for the plate P0 to be formed. In this case, the forming is gradually executed and completely up to the final shape as well. A crest-like part P2 and bottom part P1 are then formed by the roll forming at middle and final stages. In this case, the engagement part P3 passes through the gap between rolls to prevent the breakdown, At the final stage of the roll forming the side part inclined face P2a and end part engaging part P3' of the plate P0 to be formed are formed. Since the work is executed only by the roll forming in a simple shape and the change in the shape and dimension of a product can be done by the partial change in the roll equipment the production cost is reduced.

Description

Detailed Description of the Invention [Industrial Field of Application] The present invention provides a fitting portion and an end fitting which are composed of a chevron portion and a bottom portion, and which bulge inwardly or outwardly on the side slopes of the chevron portion. To form a construction board with a joint, the joint is first formed by
The present invention then relates to a method of manufacturing a construction board that can be formed extremely easily by bending the chevron portion, the bottom portion, and the end fitting portions, respectively.

[Conventional technology and its problems]

Near the summit, the cross section was formed into a corrugated shape. In folded metal plates, many types of architectural plates for fitting have been researched and developed by forming a fitting part such as a stepped part at the top or upper part of the chevron-shaped part. . Among these, there is also a construction board for fitting in which a fitting portion and an end fitting portion are formed on the inclined surfaces on both sides of the chevron portion.

It has such a fitting part and an end fitting part. As a method of forming architectural boards for fitting, they are sequentially formed by multi-stage roll forming, etc., but if the chevron part, fitting part, and end fitting part are formed at the same time, in the final stage, the The fitting part and end fitting part are complicatedly bent, making it difficult to press-form with forming rolls from above and below, which not only requires more stages but also requires a special shape that requires pressing diagonally. Furthermore, there were other problems such as the need for a molding machine and the cost of the construction boards.

Furthermore, even if the shapes of the chevron portions are approximately the same, the shape will vary depending on the shape of the fitting portion and the end fitting portion.

There is also the inconvenience of having to install a roll forming machine to form and process the architectural boards for mating, and if this is done, there are problems such as the cost of the architectural boards for mating themselves becoming extremely high. .

[Means for solving problems]

Therefore, as a result of intensive research to solve the above-mentioned problems, the inventor has developed the present invention, which consists of a chevron portion and a bottom portion.

First, upper and lower forming rolls in the initial stage form a plurality of fitting portions at predetermined intervals at predetermined intervals only at the middle position in the width direction of the plate to be formed, with the final shape having a substantially V-shaped cross section or a substantially inverted V-shaped cross section. Then, this fitting part passes through the gap between the upper and lower forming rolls in the middle and final stages, and forms a chevron part and a bottom part in the upper and lower forming rolls in the middle and final stages, and With the upper and lower forming rolls in the step, a side inclined surface and an end fitting part are formed at the outermost edge in the width direction of the board to be formed. It consists of
In addition, when forming a construction board having a fitting part that bulges inwardly or outwardly and an end fitting part on the sloped side surface of the chevron part, the fitting part is first formed, then the chevron part is formed.

〔Effect of the invention〕

In the present invention, it consists of a chevron portion P2 and a bottom portion P,
In order to form a construction board P having a fitting part P3 and an end fitting part P3 which bulge inwardly or outwardly on the side inclined surface P of the chevron part P2, first, an initial step is performed. Using upper and lower forming rolls, a plurality of fitting portions P3 each having a final shape having a substantially V-shaped cross section or a substantially inverted V-shaped cross section are formed at predetermined intervals only at the middle position in the width direction of the plate to be formed P0, and then , this fitting part P3.

While passing through the gap S between the upper and lower forming rolls at the middle and final stages, the chevron portion P is formed by the upper and lower forming rolls at the middle and final stages.
2 and the bottom part P1, and at the same time, the upper and lower forming rolls in the final stage form the side inclined surface Pem and the end fitting part P3 at the outermost end in the width direction of the plate to be formed P0. By adopting the manufacturing method for the architectural board P, firstly, the architectural board P having the fitting part P3 and the end fitting part P, which bulges inwardly or outwardly, can be formed by roll forming with a simple configuration. Second, it is a manufacturing method that can be used by only partially modifying a conventional roll forming machine for forming folded plates, making it inexpensive. Third, only the shape of the fitting part P3 is possible. Even if it is changed appropriately, it can be done relatively easily.

To explain these effects in detail, first, in the upper and lower forming rolls at the initial stage, the final shape having a substantially V-shaped cross section or a substantially inverted V-shaped cross section is formed only at the intermediate position in the width direction of the plate to be formed P0. By forming a plurality of portions P at predetermined intervals, and then passing through the gap S of the upper and lower forming rolls in the middle and final stages, the fitting portion P is By being able to form only the upper and lower forming rolls at the initial stage, there is no need for this forming later, and the bottom part P is simply formed.

and the chevron portion P2 are formed. Only roll forming has a simple configuration, and there is a great effect that the construction board P with the fitting portion P3 can be formed extremely orderly by simple roll forming.

In particular, in forming the outer side inclined surface P2+a of the chevron portion P2, which is the outermost position in the width direction, and the end fitting portion P3.
If the free end of the chevron-shaped portion P2, which is the outermost position in the width direction, is formed from the beginning, forming distortion will occur from the center side of the plate P0 toward both sides when it is sequentially bent into a folded plate shape. etc., causing a springback phenomenon to return the side inclined surface Pem at the outermost end in the width direction and the end fitting portion P3 to their old positions, resulting in a curved shape. However, in the present invention, the side inclined surface Ptm and the end fitting portion P, at the outermost end in the width direction of the plate to be formed P0 are initially No molding in stages,
By forming with upper and lower forming rolls at the final stage,
It is no longer subject to forming distortion during sequential bending forming into a folded plate shape, and it is possible to form the side inclined surface Pem at the outermost end in the width direction and the end fitting part P3 in an extremely orderly manner. Any inconvenience or problem can be eliminated.

The reason why the side slope Pem has a more arched shape than in the past is also because the side slope pza' at the outermost end in the width direction is being supported in a cantilevered manner.

In other words, if the upper and lower forming rolls are supported in a cantilevered manner and pressure forming is performed in multiple stages, the bent end fitting portion P3 and the plate to be formed P3. The molding strain generated from the center side toward both sides competes with each other to deform the side inclined surface pza and the end fitting portion P3 at the outermost end in the width direction, but in the present invention, Such problems can also be definitely solved.

Moreover, it was provided on the architectural board P. Since the fitting part P3 and the end fitting part P3 that bulge inwardly or outwardly must be able to be locked to the top and bottom of the overlapped parts, their shape is naturally as follows.
It is complicatedly bent, and in the conventional technology, it was difficult to press the molding rolls from above and below, and not only did it require more stages, but it also required the roll structure to have a special shape that allows it to be pressed diagonally.

However, in the present invention, in the upper and lower forming rolls at an initial stage, fitting portions P3 having a final shape having a substantially V-shaped cross section or a substantially inverted V-shaped cross section are formed at predetermined intervals only in the widthwise middle of the plate to be formed P0. Even if the fitting parts Pa in this state cannot be locked even if they are stacked vertically, after the final molding of the plate to be formed P0, the fitting parts P3 will become the chevron-shaped parts P2.
stood up at an appropriate angle. It is formed at the middle □ position of the side inclined surface P2+a, and furthermore, even if the side inclined surface PAIL and the end fitting part P3 are formed at the final stage, since they are at the free end position, Can be formed using upper and lower forming rolls. That is, the initial fitting portion P3 ultimately takes on a shape that looks like it has rotated or revolved, and thereby can be formed into a shape that can be locked when stacked vertically. In this way, the present invention is roughly divided into three stages: the initial □ stage, the middle stage, and the final stage. Molding of the chevron portion P2, the outermost side slope P2m in the width direction, and the end fitting portion P3
By performing the above steps separately, the building board P can be formed extremely easily using only forming rolls from above and below, and in turn, the building board P can be formed at a low cost.

Furthermore, in the upper and lower forming rolls in the middle and final stages, the chevron portion P2, the bottom portion P1, and the side inclined surface Pta at the outermost end in the width direction
and the end fitting part P3. Therefore, this roll forming machine can be used not only with a new configuration, but also with a slightly modified version of a conventional folded plate roll forming machine. It can be used for. Therefore, by adding the upper and lower forming rolls at the initial stage to a modified roll forming machine for conventional folded plate forming, the manufacturing method of the present invention can be made into an apparatus.
There is also the great advantage that the device can be manufactured very cheaply.

In addition, in the present invention, in the upper and lower forming rolls at the initial stage,
First, a plurality of fitting parts P in the final shape are formed, and then,
Due to the manufacturing method of forming the chevron portion P2 and the bottom portion P+, and finally forming the side inclined surface Ptm at the outermost end in the width direction and the end fitting portion P, the chevron portion P2 and the bottom portion P+. Even if the configured folded plate shape is constant and the shapes of the fitting portion P3 and the end fitting portion P3 change, the multiple stages of the upper and lower forming rolls in the initial stage and final stage are changed as appropriate. There is an advantage that the construction board P, in which only the shape of the fitting part P can be appropriately changed, can be molded at a very low cost.
