Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal face plate for a siding material which is used for a wall surface of a building, an exterior material and the like, and which has a deeply carved pattern and which has an improved design.

[0002]

2. Description of the Related Art A metal siding material used for an outer wall or the like is inferior in design property when the surface is flat and easily gives an inexpensive image. Therefore, a method of changing the surface with an embossed pattern, a special coating, or the like is adopted. But,
An embossed pattern formed by processing using an embossing roll is less than 2 mm even in a deep one, and has a poor three-dimensional appearance.
Even if a special paint such as stone-grain is applied, the surface does not have a three-dimensional effect, so it does not appear as a fake area. When trying to apply a deep embossed pattern to a metal strip by continuous press forming, it is necessary to press the end portion of the press with a flat plate in order to fix the formed metal strip. However, if you press the end of the press with a flat plate,
The embossed pattern attached to the metal strip is easily crushed. The collapse is more likely to occur as the emboss pattern is deeper. Therefore, in Japanese Patent Application Laid-Open No. 8-224621, in order to suppress the drawing in of the material at the time of molding while giving the design by performing two press moldings using various upper dies and lower dies, the bead shape along the feeding direction of the material and the like. A presser with the same pattern as the design is used.

[0003]

By the way, the applicant of the present invention press-molds a metal strip between a template and a soft elastic body to form an overhang corresponding to the pattern formed on the template. Japanese Patent Laid-Open No. 7-39 describes a method of attaching a portion to a metal strip
No. 963. When this method is applied to continuous press forming of a metal strip, a metal face plate for a siding material having a complicated deeply carved pattern can be easily produced. However, depending on the depth and shape of the pattern, undulation may occur at the end in the width direction of the pressed metal face plate. When large undulations occur, it becomes difficult to form a roll for forming fittings for fitting at both ends in the width direction of the metal face plate after press forming. Even if the fitting joint can be formed, the warpage of the metal face plate hinders the work of connecting a plurality of siding materials to construct a wall or the like.

The cause of the occurrence of undulations is the fins generated at the exit end of the plate retainer for fixing both ends in the width direction and the material being pulled into the center in the width direction. I and material retraction occur as follows. Irritation is caused by a partial increase in stiffness due to the formation of a deep carved pattern and a partial constraint of the material due to a plate retainer. That is, when the press-out side of the metal strip is pulled in during the press forming and is going to bend, the central part in the width direction where the rigidity is increased due to the formation of the deep engraving pattern is curved without being undone. Both end portions in the width direction do not bend in a portion having a plate retainer, but have low rigidity and are easily bent in a portion having no plate retainer. As a result, swelling occurs at the boundary of the plate presser. In addition, due to the formation of the deeply engraved pattern, the central portion is shorter than both ends in the width direction of the metal strip, and a difference in length is generated between the central portion in the width direction and both ends in the width direction in the longitudinal direction of the metal strip. While both ends in the width direction are restrained by plate holders,
The restraining force by the plate holder does not act on the central portion in the width direction where the length in the longitudinal direction of the metal strip is shortened. For this reason, the material being drawn in due to the formation of the deep engraved pattern is largely drawn into the template side at the center in the width direction as compared with the both ends in the width direction restrained by the plate retainer, and the material is drawn into both ends in the width direction. And length differences are aggregated.

[0005]

SUMMARY OF THE INVENTION The present invention is a further improvement of the method of manufacturing a metal siding material proposed above. In addition to restraining the four sides of the molded part of the metal strip, the insertion side part of the pattern forming part formed by the previous press molding is sandwiched between the template and the soft elastic body by the press molding this time, An object of the present invention is to obtain a metal face plate for a siding material which has no swelling and has improved design by a deeply carved pattern.

In order to achieve the object, the present invention intermittently feeds a metal strip into a press forming apparatus provided with a template having a joint flat portion and an embossed decorative projection. When the metal strip is pressed by pressing the template against the joint holding member and the soft elastic body which is arranged to face the joint forming flat section via the metal strip, the metal strip formed by the previous press forming is formed. Both ends in the width direction of the portion are constrained between the upper end plate presser and the lower end plate presser, and the entry side of the molded portion is placed between the entry side upper plate presser and the entry side lower plate presser. Between the flat-sided soft elastic body that protrudes to the soft elastic body side from the decorative protruding portion of the template and the decorative protruding portion of the template, It is characterized by being restrained between. As the template, for example, a template having a repetitive pattern of a raised portion for decoration and a flat portion for forming a joint portion is used.
In this case, the fixed portion on the entry side of the pattern forming portion applied to the metal strip in the previous press molding is moved to the decorative protrusion on the template having the same pattern on the template in the current press molding. When the intermittent movement and press forming of the predetermined distance are repeated, the pattern forming portion interrupted in the longitudinal direction is attached to the metal strip.

[0007] The press forming apparatus to be used restrains the metal strip to be intermittently fed on all sides of the formed part, and forms the metal strip between the soft elastic body and the joint holding tool formed with the decorative raised part. Press-forming apparatus for applying a decorative pattern to a molded portion by pressing a template against a soft elastic body with a metal strip sandwiching the portion, and a decorative raised portion partitioned by a joint forming flat surface portion , A joint holding member disposed opposite to the joint forming flat portion, a soft elastic member disposed opposite to the decoration ridge, and upper and lower ends for restraining both widthwise ends of the molded portion. A part plate retainer, upper and lower entry side plate retainers for constraining the entry side of the molded part, and a flat soft elastic body and an exit joint retainer for constraining the exit side of the molded part are provided. . The entry side of the pattern forming portion formed by the previous press molding is constrained by the press molding between the decoration projection ridge of the template and the soft elastic body. A template having a repetitive pattern of a decorative ridge and a joint forming flat portion is used, and a soft elastic body and a joint retainer are arranged corresponding to the repetitive pattern. The soft elastic body preferably has a top surface having a shape obtained by inverting the decorative ridge of the template. The decorative projecting ridge can be configured separately from the template. In this case, it is preferable to attach the decorative protrusion on the upper pressure equalizing plate via a coil spring. Also, when the entry side of the pattern forming portion formed by the previous press molding is restrained between the decorative projection ridge of the template and the soft elastic body during the current press molding, the exit side top of the soft elastic body is restrained. By partially increasing the surface, the entry side of the pattern forming portion formed by the previous press molding is preferentially restrained, and the material is prevented from being drawn into the template at the center in the width direction.

When pressing the metal strip 10 with the template 31,
The metal strip 10 is plastically deformed in accordance with the uneven shape of the decorative ridge 31a, and the brick 5 (FIG. 9) is formed. The brick portion 5 is provided with an uneven pattern 6 to which the unevenness 31c and 33a of the decorative raised portion 31a and the soft elastic body 33 are transferred. In addition, since the base and the shoulder of the brick portion 5 respectively contact the shoulder of the joint holding member 34 and the shoulder of the decorative ridge 31a, the brick is formed into a sharp shape with a clear rise from the joint 4. The metal strip 11 with the deeply carved pattern is intermittently sent out from the press forming apparatus 30 at a predetermined pitch. When sending out the metal strip 11, the fixed part 1 on the entry side of the pattern forming portion formed by the previous press molding is used.

After the fitting portion 7 and the fitting receiving portion 8 (FIG. 9) are formed at both ends in the width direction by the roll forming device 24 (FIG. 1), the foamable resin 13 is injected into the back surface side. Next, the back material 14 is overlaid and passed through the double conveyor 26. The foamable resin 13 foams between the metal strip 11 and the backing material 14.
Metal strip 11 filled with foamed resin and back material 1
After being sent out from the double conveyor 26, the laminate of No. 4 is cut to a fixed size by the cutter 27 to become a metal siding material as shown in FIG.

[0017]

When the metal strip 10 is deeply engraved by continuous press forming, _fins generated at the widthwise end 10 _edg and the outgoing side 10 _out of the metal strip 10 and the metal with the deep engraved pattern are formed. Since the widthwise central portion of the strip 11 is drawn toward the template 31, undulation is likely to occur at both ends in the width direction of the metal strip 11. If it is, the swell becomes sharp and the height of the swell increases. The metal strip 11 having such undulations
It is difficult to form the fitting part 7 and the fitting receiving part 8 at both ends in the width direction by processing the following with the subsequent roll forming device 24. Further, even if the fitting portion 7 and the fitting receiving portion 8 can be formed,
Since undulations are brought into the manufactured metal siding material, it is difficult to construct a fence, a wall, and the like by connecting a plurality of metal siding materials to each other.

On the other hand, in the present invention, the portion to be formed of the metal strip 10 to be press-formed has a widthwise end portion 10 _edg between the upper end plate presser 35u and the lower end plate presser 35d. The entry side lower plate retainer 36d and the entrance side upper plate retainer 3 are restrained.
Constrained input side 10 _in the between 6u, the sides 10 _out out between the plate-shaped soft elastic body 32 and the joint retainer 34 is restrained. Since the four sides are restrained, the metal strip 10
Even if the molded part is disposed between the template 31 and the soft elastic body 33 and the joint holding member 34 and press-molded, the material at the center in the width direction is not drawn into the template 31 side. Further, since the metal strip 11 which Fukaho pattern attached is held at the same height as the metal strip 10 which is a material, without bending in the width direction central portion, is I to delivery sections 10 _out It does not occur. By the way, even if there is the pattern overlap forming part 11 _{dp, the} outgoing side part 10 _out
When the holding at the step is omitted, the metal strip 11 bends at the center in the width direction, and _swelling is _likely to occur at a position released from the restraint of the width direction end 10 _edg , so that there is undulation at both ends in the width direction. The metal strip 11 is obtained. Therefore, no swelling is generated at the width direction end of the metal strip 11 with the deeply carved pattern, and the fitting portion 7 and the fitting receiving portion 8 can be easily formed by the roll forming device 24, and the swelling is reduced. Since no metal siding material is obtained, workability is also improved.

[0019]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A coated steel plate having a thickness of 0.35 mm and a width of 584 mm is used as a metal strip 10 and is sent from a pay-off reel 21 to a press forming apparatus 30.
Manufactured the metal strip 11 having a deeply carved pattern. As the deep carving pattern, bricks 5 of 65 mm × 130 mm in size are arranged in three rows in the longitudinal direction of the metal strip 11, and each brick 5
Adopted a brick pattern partitioned by joints 4 having a depth of 3.5 mm. During the press forming, both ends 10 _{edg in} the width direction of the metal strip 10 are sandwiched between the upper end plate holder 35 u and the lower end plate holder 35 d at 85 mm and 54 mm, respectively, and the entrance side 10 _in 100 mm is inserted into the entrance side. The effect of the pattern overlap forming portion 11 _{dp of the} outgoing side portion 10 _out and the height holding condition on the height of the swelling and the presence or absence of swelling was investigated, sandwiched between the upper side plate retainer 36 u and the entry side lower plate retainer 36 d.

As can be seen from the survey results in Table 1, the pattern overlap forming portion 11 _dp is provided, and the exit side portion 10 _out of the metal strip 11 is provided.
In Test Nos. 1 and 2 in which the metal strip 11 was sandwiched between the soft elastic body 32 or the flat pressing plate 37 and the soft elastic body 33, no generation of ole was detected, and The undulation height generated at both ends in the width direction was suppressed to 19 mm or less. Further, in Test Nos. 3 and 4 in which the irregularities 33a corresponding to the pattern overlap forming portion 11 _dp were increased by 1.0 mm, the undulation height was further reduced to 14 mm or less. Also,
Even in Test No. 7 in which the delivery side was suppressed by the flat plate 38 (FIG. 7), a deep sculpture pattern was formed in a state where there was no swelling and the undulation height was suppressed. On the other hand, even if there is a pattern overlap forming portion 11 _dp,
0 In _out of high preservation is not without test No. 5 and the pattern overlap forming unit 11 _dp Test No. 6, out I side 10 _{ou t}
And large swells having a height of 31 mm or more were generated.

Each of the metal strips 11 having the deeply engraved pattern was passed through a roll forming device 24, and the fitting portion 7 and the fitting receiving portion 8 were roll-formed at both ends in the width direction. At this time, the metal strip 11 of Test No. 6 provided with a 45 mm-high swelling was violently moved up and down in the roll of the roll forming device 24, so that the fitting portion 7 and the fitting receiving portion 8 were moved. Could not be molded. Metal strip 11 of test number 5 with swell height 31 mm
Although the fitting portion 7 and the fitting receiving portion 8 could be formed by the roll forming device 24, the formed metal strip 11 was warped in the longitudinal direction. The warping is performed by injecting foamable urethane as the foamable resin 13 into the back surface of the metal strip 11, laminating the backing material 14, heating and foaming the foamable resin 13, and then cutting the metal siding to a fixed size. Was brought into the wood.
Therefore, when a plurality of obtained metal siding materials are connected to each other to construct a wall surface, the fitting of the fitting portion 7 and the fitting receiving portion 8 is hindered. On the other hand, test numbers 1-4
Since the undulation height of the metal strip 11 was kept to 19 mm or less, the fitting portion 7 and the fitting receiving portion 8 could be easily formed by the roll forming device 24. Since the manufactured metal siding material also has no warp, the fitting receiving portion 8 can be easily fitted to the fitting portion 7, and a wall surface having an excellent appearance is constructed.

[0022]

[0023]

As described above, in the present invention, the four sides of the press-formed portion of the metal strip are restrained,
Since the metal strip is held at the same height on the press-out side and press-formed, not only decorative parts such as brick and masonry patterns with sharp contours at the base and shoulders are formed, but also sleds. It becomes a metal face plate for siding material with little undulation. For this reason, formation of a fitting part and a fitting receiving part becomes easy in a subsequent process, and construction of the obtained metal siding material also becomes easy. In addition, a three-dimensional appearance is remarkably superior to a conventional wall surface using a metal siding material, and a wall surface excellent in design and distinction can be constructed.
