In addition, since the siding accessory 1 with surface decoration in this example is made of metal, if the siding 30 is also made of metal, it is possible to bring out a sense of unity in terms of material and to make a better appearance appear on the outer wall. Furthermore, the interval between the surface decoration 3a of the covering portion 3 and the surface decoration 31 of the siding 30 is substantially constant, and packing 12 (see FIG. 12 (a)) is provided on the back surface of both end portions of the covering portion 3. If the packing 12 is interposed between the back surface of the covering portion 3 of the siding accessory 1 and the surface of the siding 30 by sticking or the like, the effect of preventing rainwater from entering can be greatly improved. In addition, in the corner wall type siding accessory 1b with a surface decoration, a central flat plate portion 13 to be described later remains in the center of the decorative convex curved portion 6 of the covering piece as shown in FIG. The portion 13 is positioned at the top of the outer wall corner as shown in FIG. 9 and can secure the appearance of the good outer wall with a sense of unity.

  The siding accessory 1 with a surface decoration (a straight wall type siding accessory 1a with a surface decoration) of FIG. 2 of this example formed by sheet metal processing of a single metal sheet A is manufactured as follows. Is done.

  First, as shown in FIG. 3, in the central area A1 of one flat plate-shaped metal original plate A, a convex curved portion 7 in which one of the front surface or the back surface is convex and the other is concave is formed by press molding. A concave curved portion 8 having a shape in which the convex curved portion 7 is reversed on the front and back sides by press molding with the flat plate-like portion 9 being spaced apart on both side regional portions A2 of the central region A1 of the original metal plate A, etc. Center pattern processing is performed. In addition, the convex curved part 7 of this example becomes a concave shape in which the front surface of the metal original plate A has a convex shape on the front side and its back surface opens on the back side, and extends in the width direction of the central region A1 of the metal original plate A. Is formed. The press forming here is a so-called drawing process, and as the metal original plate A, a coated steel plate, an aluminum plate or the like is preferably used.

  Next, as shown in FIG. 4, the metal blank A having the convex curved portion 7, the concave curved portion 8, and the flat plate-like portion 9 is punched into the developed shape of the siding accessory 1 by the external punching die. (14 in the figure is a developed shape line). In the metal original plate A in which the convex curved portion 7 and the concave curved portion 8 are formed by the press forming described above, the outer shape is drawn by being drawn into the convex curved portion 7 and the concave curved portion 8 formed by being squeezed. Although it shrinks somewhat, in this processing step, since the metal original plate A that has already been contracted in the previous processing step is punched out, the outer dimensions of the extracted workpiece (the unfolded metal original plate A) are stable.

  Next, the process proceeds to a workpiece bending process as shown in FIG. The workpiece bending process includes a leg forming process for forming the mounting leg 2 as shown in FIGS. 5 (a) to 5 (c), and the covering 3 as shown in FIGS. 5 (d) and 5 (e). A covering portion forming process is performed. Specifically, in the leg portion forming process, as shown in FIG. 5A, first, the engaging claw portions 11 are formed by bending both ends in the width direction of the unfolded metal original plate A to the front side, and then FIG. 5B. As shown in (c), both side end regions A3 of the metal original plate A are bent from the position of the center side end of each back plate 5 to the front side to form the leg plate 10. As shown in FIGS. 5 (d) and 5 (e), the covering portion forming process is performed by folding each side portion A2 of the metal original plate A back to the back so that it follows the back surface of the central portion A1. This is performed by fitting the portion 8 into the convex curved portion 7 from the back surface side (in FIG. 5 (d), the metal original plate A is bent at an acute angle by the flat plate portion 9, and continued in FIG. 5 (e). This is a state in which the metal plate A is folded back approximately 180 degrees). As a result, a covering portion 3 is formed in which a pair of back surface plate portions 5 are overlapped on the back surface of the front surface plate portion 4, and in this covering portion 3, the convex curved portion 7 and the concave curved portion 8 are centered on the front and back sides. The side decorative convex curved portion 6a is formed. Further, the mounting leg portion 2 has a shape protruding from the covering portion 3 to the back side. That is, the metal original plate A that has undergone the workpiece bending process becomes a semi-finished intermediate molded product A ′ in which the mounting leg portion 2 protrudes from the covering portion 3 to the back side. For example, a bender (bending device) can be suitably used for each of the bending processes. Moreover, although the bending process of the workpiece | work of this example is performed in order of Fig.5 (a)-(e), it is not restricted to this.

  Next, as shown in FIG. 6, press-molding is performed on the flat plate-like portion 9 in the polymerization state that constitutes both side ends of the covering portion 3 in the intermediate molded product A ′, and continues to the center-side decorative convex portion 6a. An end region pattern forming process of forming the end side decorative convex curved portion 6b is performed. The decorative convex curved portion 6 is formed by the continuous central convex curved portion 6a and the end decorative convex portion 6b, that is, the siding 30 from both ends of the covering portion 3 toward the central side. The makeup convex curved part 6 which continues to the makeup convex part 32 of the surface makeup 31 is formed. As described above, the end region pattern forming process is a process of forming the decorative convex curved part 6, that is, a process of completing the surface decoration 3 a of the covering part 3.

  Here, a makeup forming apparatus 20 that is a press molding machine as shown in FIG. The makeup forming apparatus 20 includes a die 21 for setting the intermediate molded product A ′, and a punch 22 that is driven so as to be movable toward and away from the die 21, and an opposing surface of the die 21 and the punch 22. In 21a and 22a, press molding is performed on the plate-like portion 9 in a polymerized state constituting both side ends of the covering portion 3 in the set intermediate molded product A ′ so as to be continuous with the central decorative convex portion 6a. A press working portion 23 for forming the end side decorative convex curved portion 6b is provided. The punch 22 is provided with a pressing member 24 for pressing the center side decorative convex portion 6a of the set intermediate molded product A ′, and set so that the surface side of the covering portion 3 is the die 21 side. The leg avoiding portion 25 for avoiding the mounting leg portion 2 in the intermediate molded product A ′ is recessed from the facing surface 22a.

  The pressing member 24 is attached to the punch 22 via an urging means 26 and a stopper 27. The urging means 26 has a function of urging the pressing member 24 toward the die 21 side, and the stopper 27 has a function of stopping the pressing member 24 moved to the die 21 side by the urging means 26 with a predetermined movement amount. Have Specifically, the pressing member 24 of the present example presses both outer end portions of the center side decorative convex portion 6a adjacent to the pair of end side convex convex portions 6b formed by the pair of press working portions 23. The upper end of the pair of pressing portions 24a, 24a is formed in a U-shaped cross-section formed by connecting the upper ends of the pressing portions 24a, 24a with a connecting portion 24b. The leg avoiding portion 25 is configured by a space that opens to the side. Further, the pressing member 24 is a long member that is long in the length direction of the intermediate molded product A ′, and the lower end surface of the pressing member 24 is a belt-like shape in the length direction of the intermediate molded product A ′ at the formation site of the center side decorative convex portion 6a. It is formed in a concavo-convex shape which is the same shape as the shape of the part, that is, over the band-like part in the length direction of the intermediate molded product A ′ in the formation part of the central decorative convex curved portion 6a, the intermediate molded product A ′ It is possible to hold down. In order to attach the long pressing member 24 to the punch 22, a plurality of urging means 26 and stoppers 27 are provided in the length direction of the punch 22 at a predetermined interval. The biasing means 26 is constituted by a spring in this example, but an air spring or the like may be used, for example.

  In this way, the pressing member 24 is mounted on the punch 22 so as to be movable in the contact / separation direction between the punch 22 and the die 21. The pressing member 24 in the normal state is positioned on the die 21 side by the urging force of the urging means 26, and the movement to the die 21 side is restricted by the stopper 27, and the tip of the pressing member 24 faces the surface of the punch 22. It protrudes toward the die 21 side.

  According to this makeup forming apparatus 20, an end region by press molding is performed on the intermediate molded product A ′ so that the intermediate molded product A ′ is sandwiched between the press-worked portions 23 of the punch 22 and the die 21 that are close to each other. Pattern formation processing is performed, but when the punch 22 is brought close to the die 21, the pressing member 24 moves the intermediate molding A ′ prior to press molding of the intermediate molding A ′ by the press working unit 23. The center side decorative convex part 6a is pressed against the central side decorative convex part 6a. The pressing member 24 continues to the center of the intermediate molded product A ′ at the time of press molding to the intermediate molded product A ′ by the press processing unit 23 which is further performed by bringing the punch 22 closer to the die 21. The side decorative convex curved portion 6a is kept pressed. That is, it is possible to perform the press molding to the intermediate molded product A ′ by the press working unit 23 in a state where the central decorative curved portion 6a is securely pressed by the pressing member 24.

  In the end area pattern forming process, only the flat plate-like part 9 in the polymerized state constituting both side ends of the covering part 3 in the intermediate molded product A ′ is subjected to press forming such as drawing to form the covering part. Only the end-side decorative convex portion 6b of the decorative convex portion 6 formed in FIG. In other words, the area of the processing portion of the covering portion 3 to be press-molded is small, and this processing portion is the end in the width direction of the covering portion 3 where the metal is easily spread by press forming. It is possible to reduce the influence of deformation or the like due to press molding on the part of the intermediate molded product A ′ other than the part. Furthermore, in this example, in the state where the center side decorative convex portion 6a is pressed by the pressing member 24 as described above, the intermediate molded product A ′ by the press working portion 23 is formed so as to form the end side decorative convex portion 6b. Therefore, the influence of deformation or the like on the central side decorative convex portion 6a due to the press molding is also surely eliminated. Therefore, good dimensional accuracy could be ensured for the siding accessory 1 with surface decoration completed through the end region pattern forming process.

  In addition, in FIG. 9, the manufacturing process of the siding accessory 1 (corner wall type siding accessory 1b) of FIG. 8 of this example is shown. The corner wall type siding accessory 1b is basically manufactured by following the manufacturing method of the straight wall type siding accessory 1a. Specifically, in the central zone pattern forming process, the convex curved portion 7 is formed in the central zone A1 of the metal original plate A so as to leave a flat central plate-like portion 13 at the center of the metal original plate A, and an end portion. After the area pattern forming process, the bent portion forming device 60 is used as shown in FIG. 9 (e), and it is folded at about 90 degrees so that the front side is convex at the central flat plate portion 13 at the center of the covering portion 3. The bending part forming process for forming the bent part 15 by bending is different from the manufacturing method of the straight wall type siding accessory 1a. In the figure, 61 is a V-bending die in the bent portion forming apparatus 60, and 62 is a V-bending punch.

  As in the above manufacturing method, first, the bent portion 7 and the recessed bent portion 8 which are the central decorative bent portion 6a constituting most of the decorative bent portion 6 in the surface makeup 31 of the covering portion 3 are accurately bent. An intermediate molded product A that is formed by press molding so as to leave a flat plate-like portion 9 that can be processed, and is then bent by the flat plate-like portion 9 to provide the covering portion 3 and the mounting leg portion 2. ′, And only the end-side decorative convex portion 6b, which is the remaining portion of the central-side decorative convex portion 6a in the decorative convex portion 6, is formed by press molding on the intermediate molded product A ′. By providing the convex part 6, the surface decoration 3a having a three-dimensional pattern is applied to the covering part 3 by sheet metal processing such as bending processing or press processing (punching processing or drawing processing) on a single metal original plate A. Applied to the siding 30 having the surface makeup 31 On the other hand, it is possible to manufacture the siding accessory 1 with a surface makeup that can ensure a good appearance and improve the effect of preventing the intrusion of rainwater. In addition, the pressing member 24 presses the center-side decorative convex portion 6a. In the attached state, by pressing the intermediate molded product A ′ by the press working unit 23 to form the end side decorative convex portion 6b, the center side decorative convex portion 6a by press molding is formed. Since the influence of deformation or the like could be eliminated without fail, good dimensional accuracy could be ensured for the siding accessory 1 with surface decoration.

  In the makeup forming apparatus 20 of the above embodiment, the pressing member 24 is attached to the punch 22. However, if it is possible to press the center side decorative convex portion 6a, the pressing is performed against the die 21. The member 24 may be attached.
