Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a rising part,
The present invention relates to a method for forming a construction board and a forming apparatus therefor, which are capable of integrally forming a hook-shaped portion consisting of a top portion and an inclined portion in a reliable and orderly manner.

2. Description of the Related Art Conventionally, various shapes of architectural boards constituting an outer enclosure such as a roof or a wall have been developed.

Among them, there is a construction board that has an engaging portion formed on one side and a hook-shaped portion formed halfway on the other side. To construct a roof or wall with this, attach the other side attachment part of the construction board to a structural member such as a main building, engage the engaging part of the adjacent construction board with this hooked part, and then attach these parts. Construction is being carried out repeatedly. At this time, it is desirable that the hook-shaped portion be bent into a hook shape, and by doing so, the engagement can be made more reliable and the outer envelope can be made stronger. However, when trying to integrally form a hook-shaped part in the middle of a flat part of a construction board using multiple groups of forming rolls, it is necessary to support the lower forming roll inside the hooked part due to the roll structure. It is extremely difficult. In other words, in order to bend into a hook shape, the corner must be pressed by the upper and lower forming rolls to form a hook shape, exceeding the elastic limit, and in a configuration where the lower forming roll is not attached, the hook shape is The parts cannot be formed neatly. For this reason, in order to form a hook-shaped part in the middle of one side of a flat part, the hook-shaped part must be divided into two parts, and the manufacturing of the construction board is extremely troublesome. However, it also had the disadvantage of making construction boards expensive. Therefore, in the present invention, a rising portion is bent from one end of the flat portion, a top portion is formed inwardly from this upper end, an edge portion is subsequently provided below, and the portion is bent again from this lower end to extend outward from the lower end of the rising portion. In order to form a construction board with a horizontal attachment part formed on one side, a rising part is bent on a flat plate-shaped workpiece using one side roll of a plurality of upper and lower forming rolls at an initial stage;
In addition, the sides corresponding to the edges and tops are bent in a substantially perpendicular manner directly above the rising portions, and then the edges and tops are slightly bent with side free rolls, and the lower side of the tops is formed with a guide shaft. A forming method may be used in which the top and edges are finally formed with one side roll of the upper forming roll in the final stage, or a large number of upper and lower forming steps are performed to sequentially form the above-mentioned building board. In a forming machine equipped with a group of rolls, at the initial stage, one side roll of the upper and lower forming rolls is installed with the side corresponding to the edge and top standing up almost vertically almost directly above the rising part, and at the middle stage. , the edge and the top are supported by a side free roll that is slightly bent, and in the final stage, a guide shoe is provided that comes into contact with the lower side of the top, and the top and edge are pressed to final form the top and edge. By using a forming device equipped with one side roll of the upper forming roll, the edge, top, and rising part of a single flat plate can be integrally and reliably and orderly bent in the middle of one side of the flat part. Therefore, it is possible to easily and quickly manufacture a building board having a desired shape, and the product can be provided at a low cost, thus solving the above-mentioned drawbacks.

1b], the side corresponding to the folded edge P of the mountain-shaped portion P8 is bent into a gently inclined side and a horizontal side, respectively (
(See Figures 1 and 1 in Figures 20). Next, one side roll of the second upper and lower forming rolls 2a and 2b further bends one side of the flat part P, and the horizontal side is made into a gently sloped side so that the outer end side is lowered. It is formed into a mountain shape, and the gently sloped side is further bent by the other side roll to form a sloped side (see 2 in FIG. 20). Then, by one side roll of the third upper and lower forming rolls 3a and 3b, the inclination angle of both inclined sides formed in a mountain shape is increased, the inner inclined side is further bent into two sides, and the other side is bent. With the side rolls, the inclination angle of the inclined side is further increased (see FIGS. 2 and 3 in FIG. 20). Next, the fourth upper and lower forming rolls 4a, 4

One side roll of b is bent so as to further increase the angle of each sloped side in the fourth stage, and the other side roll is used to incline the inside sloped side to an even steeper angle. ,
At the outer end of the outer gently inclined side, a side corresponding to the folded edge P9 is bent into a slightly arc shape (see FIGS. 4 and 5 in FIG. 20). Next, with one side roll of the sixth upper and lower forming rolls 6a and 6b, each inclined side is further steeply inclined, 3 sides are bent as the side corresponding to , and at the other side roll, the inner inclined side corresponding to the mountain-shaped portion P8 is further inclined further steeply, and the side corresponding to the folded edge P9 is further bent inward. (See Figures 5 and 6 in Figure 20). Then,
It is further bent by one side roll of the seventh upper and lower forming rolls 7a and 7b, so that the side corresponding to the top part P3 and the edge part P4 is formed into a substantially vertical shape, and the other side roll is used to form a mountain-like part P8. The inner slope side is steeply sloped for final forming, and the side corresponding to the folded edge P9 is further bent (at this time, the bent portion is formed in an arc shape. See 7 in FIG. 20). Next, with one side roll of the eighth upper and lower forming rolls 8a and 8b,
The rising part P2, the horizontal attachment part P6, the rising edge P7 is finally formed, the top part P3 is slightly narrowed between both sides of the substantially vertical shape corresponding to the edge P4, and the side corresponding to the folded edge P9 is formed using the other side roll. (Fig. 6, 8 in Fig. 20)
reference). Then, in the ninth stage, side free roll 9
'A, 9'b, an enlarged part P5 is formed at the upper end of both sides corresponding to the top part P3 edge P4, and the lower part thereof is formed in close contact except for the rising part P2, and other than the architectural board P. The side folded edge P is further bent by a side pressing roll 27 (see FIGS. 7 and 9 in FIG. 20). Next, in the 10th and 11th stages, the side free roll 10'A
,lO'B,l"A,ll"b, top P3 edge P4
The approximately vertically bent side corresponding to , is bent at one point in the middle, and is sequentially bent as the side corresponding to the edge P4, and the folded edge P9 is further bent by the side pressing roll 27 in the tenth stage, The folded edge P9 is finally formed by the side pressing roll 27 in the 11th stage (Fig. 8, 10 in Fig. 20,
(See No. 11). Then, in the twelfth step, the side corresponding to the edge P4 is further bent on the side free roll 12''A, l7b, and the bending angle with respect to the vertical side corresponding to the top P3 is adjusted to a desired angle. The edge portion P4 is finally formed, and the side corresponding to the outer inclined side of the mountain portion P8 is slightly bent using the other rolls of the twelfth upper and lower forming rolls 12a and 12b (as shown in FIGS. 9 and 20). 12).Next, in the 13th step, the side free roll 13''A, l3
At "b", the vertical side corresponding to the top part P3 is slightly bent from the upper end of the rising part P2, and the other side roll of the thirteenth upper and lower forming rolls 13a and 13b is used to bend the vertical side corresponding to the top part P3 to the outside of the mountain part P8. The side corresponding to the inclined side is further bent (see FIGS. 10, 11, and 13 in FIG. 20). Then, in the 14th step, the side free rolls 14''A, 14''b are bent to the top P3. The corresponding side is further bent, and the other side rolls of the fourteenth upper and lower forming rolls 14a and 14b are used to make the bending angle between the outer inclined side of the mountain-shaped portion P8 and its top side a desired angle, and then Final shaping of the outer inclined side (No. 14 in Fig. 20)
reference). In the 15th step, a guide shoe 29 and a 15th upper forming roll 15a provided on the lower side of the inclined side corresponding to the top P3 [on the inside formed by the edge P4, the top P3, and the rising part P2, and on the back side of the top P3] With one side roll,
While fixing the rising portion P2, press the upper side of the side corresponding to the top P3 to form a bend, and use the other side rolls of the fifteenth upper and lower forming rolls 15a and 15b to form the mountain-like portion P8. The top side relative to the inside inclined side is bent so as to be nearly horizontal (see FIGS. 12 and 15 in FIG. 20).
Then, in the 16th step, the side corresponding to the top portion P3 is finally bent with respect to the rising portion P2, and the other side roll of the 16th upper and lower forming rolls 16a and 16b is used to form the mountain-like portion P.
8 is finally bent approximately horizontally (see FIG. 13, FIG. 14, and FIG. 20, FIG. 16). At this 16th stage,
Architectural board P is formed. Then, the construction board P formed in the 16th step is passed through the 17th upper and lower forming rolls 17a and 17b, and the board is fed out and subjected to strain relief forming. Note that 35a and 35b are upper and lower corrugated rolls in the preliminary stage, which are supported between the side plates 19 and 19 at a position before the first stage, and the upper corrugated roll 35a and the lower corrugated roll 3
The corrugations 5b are fitted to form a flat workpiece P.

It may also be formed into a corrugated shape in the longitudinal direction (see Fig. 22). An upper gear 23 and a lower gear 24 mesh with the upper and lower corrugated roll shafts 35a and 35b, respectively, and the lower corrugated roll 35
It is driven by the rotation of the chain wheel 25 at the end of the shaft b. When the upper and lower corrugated rolls 35a and 35b are passed through, a corrugation is formed on the construction board P, and it is also possible to form the construction board P without providing the upper and lower corrugated rolls 35a and 35b. There is also. Next, the effects will be explained.

First, in the invention of the method for forming a construction board as described in claim 1, a flat plate-shaped workpiece PO is formed by one side roll of a plurality of upper and lower forming rolls at an initial stage. The portion P2 is bent, and the side corresponding to the top portion P3 of the edge portion P4 is bent approximately vertically directly above the rising portion P2, so that the rising portion P2 is bent from one end of the flat portion P1. Architectural board P, in other words, a flat board, has a top part P3 formed inward from the upper end, followed by an edge part P4 below, and is folded back from this lower end to form a horizontal attachment part P6 outward from the lower end of the rising part P2. In the middle of the section, there is a rising section P2 and a top section P.
In order to bend and form the hook-shaped portion consisting of the three edges P4, first, most of the construction board P can be reliably bent by forming only the upper and lower forming roll groups at the initial stage, and there is no waste in the forming order. It can be done without

Next, the edge P4 and the top P3 were formed into a slight bend using a side free roll, and then the edge P4 was finally formed using a side free roll, so that the edge P4, which had already been made vertical, was formed with a slight bend.
The edge P4 of the side corresponding to the top P3 can be bent to an extremely accurate bending angle by applying pressure from both sides. and,
By bending the side corresponding to the vertical upper edge P4, the width of the actual bending is small, the diameter of the side free roll can be reduced accordingly, and the roll configuration is also simple. Can be done. Generally, when roll-forming a metal plate, the plate is pressed from above and below or from the left and right, thereby ensuring that the plate exceeds its elastic limit and is easily plastically deformed. However, it is a narrow space to final form the edge P4 in this way and to support the roll located on the lower side inside the slightly bent, almost hook-shaped top part P3. In addition, it must be provided directly below the upper forming roll, which is technically extremely difficult. Therefore, in the method of the present invention, the lower side of the top part P3 is supported by the guide shoe 29, and the top part P3 is pressed by one side roll of the upper forming roll in the final stage to finally form the top part P3. Therefore, the top part P3 can be bent by pressing from two places above and below, while fixing the bending corner part.
It can be bent in an extremely orderly manner. In this way, the architectural board P
This complex shape can only be reliably formed by sequentially forming the product using upper and lower forming rolls and side free rolls, and then final forming using the upper forming roll and guide shoe. Next, in the invention of the construction board forming apparatus described in claim 2, the flat part P1
A standing earth part P2 is bent from one end, a top part P3 is formed inward from this earth end, and an edge part P4 is subsequently provided below,
In a forming machine equipped with a large number of upper and lower forming roll groups, etc., which sequentially forms a building board P which is folded back from the lower end to form a horizontal attachment part P6 outward from the lower end of the rising part P2,
At the initial stage, an edge P4 and a top P3 are formed almost directly above the rising portion P2.
Since one side roll of the upper and lower forming roll group is provided with the side corresponding to the side rising approximately vertically, a rising part P2 is formed between the flat part P1 and the horizontal attachment part P6, which constitutes the majority of the construction board P. In addition, the vertical side corresponding to the edge P4 and the top P3 can be reliably and orderly bent using only the upper and lower forming roll groups. The configuration of this forming roll group is simple;
A role configuration with relatively few stages is possible. Furthermore, in the middle stage of the device, since the side free rolls that slightly bent the edge P4 and the top P3 and the side free rolls that final formed the edge P4 were supported, the edge P4 and the top P3 were bent vertically in the initial stage. By pressing from both sides, the material at that location can be easily bent to exceed its elastic limit, and the bending angle can be made orderly and reliable.
Only side free rolls are supported on both sides of the vertically bent sides, and the structure is extremely simple. Further, in the present invention, in the final stage, a guide shaft 29 is provided that comes into contact with the lower side of the top portion P3, and a roll on one side of the upper forming roll that presses the lower surface of the top portion P3 to finally form the top portion P3 is provided. As a result, the top part P3 is turned into a rising part P by vertical pressure between the guide shaft 29 below the top part P3 and one side roll of the upper forming roll above the top part P3.
2. Bending molding can be performed extremely orderly and reliably from the upper end. As described above, it is technically difficult to provide a roll that supports the top part P3 under the top part P3 and directly under the upper forming roll inside the bent state of the top part P3, that is, inside the substantially hook-shaped part. The guide shaft 29 has a simple structure, is easy to install, and can be made compact. Moreover, it has revolutionary effects such as being able to form architectural boards P with complex shapes for the first time. . The upper surface of the guide shaft 129 is not in rolling contact but in sliding contact with the lower surface of the top P3 of the architectural board P, and during molding, small deformation and strain may occur on the lower surface of the top P3 depending on the material, but it is also the inner surface, and experimentally However, there is no support for its commercialization. In addition, the guide shoe 12
If only both sides of the top portion P3 are configured so as to contact the lower surface of the top portion P3, the above-mentioned deformation strain 1', wrinkles, etc.) will not occur, and more orderly bending can be performed.

In addition, if upper and lower forming rolls 35a and 35b are provided in front of the first upper and lower forming rolls 1a and 1b in a longitudinal direction in a corrugated manner (the height is actually about 1 to 2), it is possible to pass through the corrugated upper and lower forming rolls 35a and 35b. By bending forming using a group of rolls according to the present invention, it is possible to commercialize a product in which corrugated portions are formed in each part, and it is possible to provide an even stronger forming apparatus and method for forming a building board P. Also, as a method or forming apparatus, the side corresponding to the top P3 and the upper end of the rising part P2 are bent, and then the edge P4 is bent from the top P3 end. This is done in a bending order or device with support for the bending.
