DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a molding apparatus for building exterior materials installed for the purpose of protecting and decorating an outer wall of a building, and more particularly, to a hard iron plate having a relatively small stretching ratio. The present invention relates to a molding device for an architectural exterior material excellent in round molding workability and productivity without forming another cut portion in a connecting side portion at the time of round bending at a square top portion in the exterior material of the above. It is.

[0002]

2. Description of the Related Art In general, a building exterior material is manufactured in an arbitrary size, and is attached to an outer wall of a building as a unit in a state of being connected in a large number in order to protect the outer wall and to treat an outer exterior. It is used. Although such exterior materials have been used in various patterns in the past, due to the manufacturing cost and workability, colored exterior materials for building material panels, which are obtained by bending iron plate materials and applying paint treatment, are the most commercialized. Have been.

[0003] As shown in FIG. 11, a conventional steel plate material is prepared by preparing a square or rectangular steel plate (iron plate) 110 as shown in FIG.
After performing the work of engraving the zero and second fold curves 130, the four corners of the steel plate 110 are cut at right angles to the first fold curve 120 to form cut portions, and the respective fold curves 110 and 120 are formed.
The peripheral part is bent by a forming device along the decorative surface part 14.
0, a small width side part 150 bent downward in a direction perpendicular to the decoration surface part 140, and the side parts 150
From the decorative surface portion 140
And an extension 160 having a surface parallel to the surface of the unit body was formed to form the exterior material of the unit body. The exterior material manufactured by such a forming method is cut to the first fold curve 120 at the cut portion provided at the four corners in order to ensure the easiness of the fold forming. Since the decorative surface 140 is extended to the four corners and exposed to the surface, a welding operation must be performed on each corner to prevent water leakage. Accordingly, the flatness of the exterior material is reduced due to an increase in the number of work steps due to the production of the exterior material and the occurrence of thermal deformation of the decoration surface due to the welding process, and the four corners of the decoration surface are formed into a right angle to improve the appearance. Is reduced.

[0004] In order to overcome the above-mentioned problems of the molding of the exterior material, the present applicant has proposed to manufacture the exterior material by a molding apparatus as shown in FIG. 17948). That is, an incision 210 that is circularly connected and cut on both sides of the steel plate 110 is positioned between the first fold curve 120 and the second fold curve 130, and the first fold curve 120 and the second The decorative surface 140, the side 150, and the extension 16 are formed by forming along the folding curve 130.
0 was formed to manufacture the exterior material 200. Such a method of forming an exterior material includes, when bending along the first fold curve 120, rounding processing of the four corner vertices of the decorative surface portion 140, so that the corners where the first fold curves 120 meet are formed. In a state where the protrusion 220 was not bent completely but was partially bent to form the unformed protrusion 220 at the corner, this was round-formed by a forming apparatus. That is, the side portion 150
A lower mold 230 having a round surface 240 to be molded on the inner side of the inside and the lower surface of the corner top of the decorative surface portion 140
The pressing roller 250 having an arcuate round groove 260 corresponding to the round surface 240 of the lower mold 230 is lowered in the direction of the arrow so that the unformed protrusion 220 is The projecting portion 220 was rounded by the pressurizing and rolling action of the arcuate round groove 260 of FIG. 250 to manufacture the exterior material 200 as a complete product (see FIG. 13).

As described above, in the prior application technology of the present applicant,
At the time of rounding the four corners of the decorative surface part 140, the protruding part 220 is pressure-formed by the pressure roller 250. In this process, the deformation (stretching) due to the difference in radius between the round corner 120a (FIG. 13) of the first folding curve 120 and the round cutting portion 210a of the cutout 210 is absorbed by the cutting portion 210, and the molded portion thereof is formed. Since the effect of absorbing the distortion is provided, round processing of the corners by molding is possible. Further, since the cut portion 210a is located on the side surface portion 150 between the first bent curve 120 and the second bent curve 130, it is not necessary to weld the cut portion 210 by construction.

[0006] However, such a molding apparatus is not suitable for use in a case where the material of the exterior material to be molded is a soft material such as aluminum. However, when the molding material is a hard iron plate having a low elongation ratio, there is a drawback that the molding is not performed normally and a break occurs.
In particular, such a molding apparatus is provided with the pressure roller 250.
At the time of round forming of the protrusion 220 formed at the four corners by the above, in order to absorb the amount of deformation that is extended by the forced pressure forming, the cutting part 210a is always necessary,
In order to minimize the molding failure rate, the lower mold 230 is installed as a fixed mold, and the pressing roller 250 is formed by a forced pressing action by a rolling action while preventing breakage such as breakage of a formed portion. It has become.

However, such a technique has a disadvantage that, as described above, when the material of the exterior material is a hard iron plate, the forming speed is limited, so that workability and productivity are reduced. In particular, the cutting section 210a is necessary to absorb the deformation amount due to the molding, which complicates the work process and increases the cost.

[0008]

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a molding apparatus according to the present invention will be described with reference to the accompanying drawings. As shown in FIGS. 1 to 3, the apparatus of the present invention comprises a lower forming means 10 positioned to support the inside of the side surface 4 of the exterior material 1 and the lower surface of the corner of the decorative surface 3, Clamping means 30 for pressurizing and fixing the decorative surface portion 3 of the exterior material 1 located at the upper part of the molding means 10 by a fixing plate 32 attached to the tip thereof by raising and lowering an operating rod 31 of a hydraulic or pneumatic cylinder.
And pressure bending means 20 for bending the unformed protrusion 2 of the exterior material 1 fixed by the clamping means 30. The lower forming means 10 includes a movable fixed plate 1.
A lower mold 12 having a molding round surface 13 is provided on the upper part of the apparatus 1, and slide holes 14 are formed in the movable mold fixed plate 11 on both front and rear sides, and are fitted to guide posts 15 so as to be able to move up and down. The fixed state is maintained by the elastic force of the compression springs 16 and 17. The pressure bending means 20 has slide holes 22 on both sides of a pressure plate 21 so that both guide posts 2 are formed.
The upper and lower surfaces of the lower mold 12 are normally mounted on the upper and lower surfaces of the lower mold 12 by a hydraulic or pneumatic cylinder operating rod 25 coupled to the center. Maintained in a fixed position,
A molding end 26 having an arcuate round groove 27 corresponding to the molding round surface 13 of the lower mold 12 is provided. The molding end 26 has a round portion 26a formed between the lower surface and the front molding surface, so that when the hydraulic rod or pneumatic cylinder is lowered by the operating rod 25, the unmolded projection 2 Bends while applying soft pressure.

FIGS. 4 to 9 show a process of round-forming the unformed protruding portion 2 of the square portion generated in the process of bending and forming the building exterior material 1 by the forming apparatus of the present invention thus configured.
This will be described below based on First, the unformed protrusion 2 of the exterior material 1 is positioned above the lower mold 12 of the lower forming means 10, and the inner surface of the already bent side portion 4 and the lower surface of the corner portion of the surface decoration portion 3 are fixed. It is settled on the molding round surface 13 in a close contact state (see FIG. 4). In this state, the operating rod 31 of the hydraulic or pneumatic cylinder of the clamping means 30 is operated to descend, and the fixing plate 32 at the tip positions the corner where the unformed protrusion 2 of the surface decoration portion 3 of the exterior material 1 is located. The lower forming means 10 is gradually lowered while the upper surface of the portion is fixed by pressure bonding (see FIG. 5). In this state, the operating rod 25 of the hydraulic or pneumatic cylinder of the pressurizing / folding means 20 is moved down earlier than the operating rod 31 of the hydraulic or pneumatic cylinder of the clamping means 30, and the lower forming means 10 The unformed protrusion 2 is round-formed by the arc-shaped round groove 27 of the formed end 26 passing through the unformed protrusion 2 of the exterior material 1 fixed to the lower mold 12 while pressurizing (FIG. 6, FIG. (See FIG. 7).

As described above, simultaneously with the lowering operation of the lower forming means 10, the pressing / folding means 20 descends faster than the lowering speed of the lower forming means 10 to round the unformed protruding portion 2 of the exterior material 1. Since the molding is performed, even if the exterior material 1 is an iron plate having a relatively small elongation ratio, the unformed protrusion 2 is not damaged in the molding process, and the round groove 27 of the molded end 26 is Since the round portion 26a is formed between the upper surface and the upper surface, it is possible to perform a soft molding while dispersing a vertical stress due to bending in a molding process. Thereafter, in order to round-mold the other unformed protrusion 2 of the exterior material 1, first, when the operating rod 31 of the clamping means 30 is raised, the movable plate 11 of the lower forming means 10 is compressed. Due to the resiliency of the spring 17, it rises along the guide post 15 in a state in which the exterior material 1 is in close contact between the fixing plate 32 and the lower mold 12, and the resilience of the compression spring 17 and the upper When the resilient force of the compression spring 16 becomes the same, the movable fixed plate 11 stops, and only the operating rod 31 further rises (see FIG. 8). In this state, the exterior material 1 is separated from the lower mold 12 of the lower forming means 10, and when the operating rod 25 of the pressure bending means 20 is raised, the pressure plate 21 is vertically raised along the guide post 23. Then, it returns to the predetermined position (see FIG. 9).

In this state, after the unformed protrusion 2 of the exterior material 1 is again positioned on the lower mold 12 of the lower forming means 10, the clamping means 30 is fixed. In an iterative operation process according to the above operation sequence, the unformed protrusion 2 of the exterior material 1 is formed, and the deformed protrusion 2a protruding from the end surface of the protrusion is formed.
Can be obtained to obtain a beautifully structured exterior material 1 as shown in FIG. As described above, according to the present invention, the lower forming means 10 for supporting and fixing the unformed protrusion 2 of the exterior material 1 is lowered, and at the same time, the pressing / folding means 20 is lowered at a speed higher than the lowering speed of the lower forming means 10. Meanwhile, since the unmolded protrusion 2 is pressed and lowered at the molding end 26 having the round groove 27 to perform the molding operation, it is possible to mold the hard material exterior material as compared with the existing fixed mold molding apparatus. The molding operation is continuous and quick, and the productivity can be significantly improved.

[0015]

As described above in detail, according to the present invention, in manufacturing an exterior material, round processing of a square portion where a decorative surface portion and a side portion meet can be easily performed, and particularly, pressure molding is performed. Excellent production workability can be achieved even with a hard iron plate material with a small deformation rate (stretch rate). Also, at the time of round bending processing of the square part of the decoration surface exposed to the outside of the exterior material, The round molding is possible without forming another cut portion on the connecting side portion, thereby simplifying the working process, and thus providing an inexpensive building exterior material suitable for mass production. I can do it.
