Description

  The present invention relates to a siding accessory and a method for manufacturing the same.

  Between the adjacent sidings 30 having the three-dimensional pattern surface makeup 31, the mounting legs 2 that are attached to the accessory mounting body 40 disposed from the back side thereof and the adjacent sidings 30 are disposed adjacent to each other. For example, Patent Document 1 is known as a siding accessory 1 including a covering portion 3 that covers an end surface of a siding 30 as shown in FIG. However, the siding accessory 1 of Patent Document 1 is formed by assembling two members, a leg member 50 constituting the mounting leg 2 and a covering member 51 constituting the covering 3. There is a problem that its manufacture is complicated.

  Moreover, as what formed the siding accessory 1 provided with the attachment leg part 2 and the coating | coated part 3 with the metal original plate A of a sheet, patent document 2 is known as FIG. 11 (a), for example. ing. Specifically, the covering portion 3 is formed by folding a single flat metal plate A and a pair of back surface plate portions 5 overlapped on the back surface of the front surface plate portion 4. It is formed by bending the end of 5 to the back. However, the surface of the covering portion 3 in the siding accessory 1 of Patent Document 2 has a flat shape, and the surface portion 3a having a three-dimensional pattern is not applied to the covering portion 3 as in Patent Document 1. Therefore, as shown in FIG. 11B, when the siding accessory 1 of Patent Document 2 is disposed between the sidings 30 having the three-dimensional surface makeup 31, the siding accessory 1 having a different surface appearance is obtained. The appearance of the outer wall constituted by the siding 30 is disturbed, and the gap S, which has a different width in the front and back direction depending on the location, between the back surface of the covering portion 3 of the siding accessory 1 and the front surface of the siding 30. If s is generated, even if the packing 12 is interposed between the siding accessory 1 and the siding 30, there is a problem that effective water stoppage against rainwater that enters is impossible.

  Here, a three-dimensional surface makeup 3a that is continuous with the surface makeup 31 of the siding 30 is applied to the covering portion 3 of the siding accessory 1 formed of a single metal original plate A as in Patent Document 2. Then, for example, when the metal base plate A is folded to form the covering portion 3 and the metal base plate A is bent to form the mounting legs 2, and then the surface decoration 3a is applied to the covering portion 3 by press molding or the like, The mounting leg portion 2 protruding from the covering portion 3 obstructs the forming process of the surface decoration 3a. For example, the surface of the covering portion 3 is formed before the metal plate A is folded back to form the covering portion 3. When the makeup 3a is applied, the surface makeup 3a prevents the metal base plate A from being folded when the covering portion 3 is formed. That is, for reasons of manufacturing as described above, in the siding accessory 1 formed of one metal original plate A, the surface that is continuous with the three-dimensional pattern surface makeup 31 of the siding 30 with respect to the covering portion 3. At present, the makeup 3a is not realized.

That is, a siding accessory 1 that can be obtained by easy manufacturing, can ensure a good appearance with respect to the siding 30 having the surface makeup 31, and can also improve the effect of preventing the intrusion of rainwater, and a manufacturing method for realizing the siding accessory 1. This is the current situation.

The effect of preventing rainwater from entering can be improved. Since the siding accessory 1 of this example is made of metal, if the siding is also made of metal, a sense of unity can be given in terms of material and a better appearance can be displayed on the outer wall. More specifically, the distance between the front and back surfaces 3a of the cover 3 and the surface 31 of the siding 30 is substantially constant, and the packing 12 (see FIG. 11 (a)) If the packing 12 is interposed between the back surface of the covering portion 3 of the siding accessory 1 and the front surface of the siding 30, the rainwater intrusion prevention effect can be greatly improved. In the corner wall type siding accessory 1b, as shown in FIG. 7, a central flat plate portion 13 described later remains in the center of the decorative convex curved portion 6 of the covering piece. Since it is located at the top of the outer wall corner as shown in FIG. 9, it can be ensured without losing the appearance of a good outer wall with a sense of unity.

  The siding accessory 1 (straight wall type siding accessory 1a) of FIG. 1 formed by sheet metal processing of a single metal original plate A is manufactured as follows.

  First, as shown in FIG. 2, in the central region 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. 3, 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. 4A to 4C, and the covering 3 as shown in FIGS. 4D and 4E. A covering portion forming process is performed. Specifically, in the leg portion forming process, as shown in FIG. 4 (a), 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. 4 (b). 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. 4 (d) and 4 (e), the covering portion forming process is performed by folding back both sides A2 of the metal original plate A to the back with each flat plate portion 9 so as to be along the back surface of the center region A1. This is performed by fitting the portion 8 into the convex portion 7 from the back side (in FIG. 4 (d), the metal original plate A is bent at an acute angle by the flat plate portion 9, and in FIG. 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.4 (a)-(e), it is not restricted to this.

  Next, as shown in FIG. 5, press-molding is performed on the flat plate-like portion 9 in the polymerized state that constitutes both ends of the covering portion 3 in the intermediate molded product A ′, and continues to the center-side decorative convex portion 6a. The 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. Here, the pressing member 24 is mounted so as to be movable in the contact / separation direction between the punch 22 and the die 21 via an urging means 26 constituted by a spring. In response to the urging means 26 urging the die 21, the tip of the urging means 26 protrudes further toward the die 21 than the opposing surface of the punch 22.

  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, in the state where the center side decorative convex portion 6 a is pressed by the pressing member 24, the press processing unit 23 performs press molding to the intermediate molded product A ′.

  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. Further, in this example, the press working part 23 presses the intermediate molded product A ′ with the pressing member 24 pressing the center side decorative convex portion 6a as described above. It is also attempted to eliminate the influence of deformation or the like on the side decorative convex curved portion 6a. Therefore, good dimensional accuracy can be ensured for the siding accessory 1 completed through the end region pattern forming process.

  In addition, in FIG. 8, the manufacturing process of the siding accessory 1 (corner wall type siding accessory 1b) of FIG. 7 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, a bent portion forming device 60 is used as shown in FIG. 8E, and the front side is convex at the central flat plate-like portion 13 at the center of the covering portion 3 so that the front side is convex. 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, the siding accessory 1 capable of ensuring a good appearance and improving the effect of preventing the intrusion of rainwater could be manufactured easily and with high dimensional accuracy.
