Embodiments of the punching plate 7 of the present invention will now be described with reference to the drawings. FIG. 1 shows a punching plate 7 according to a first embodiment of the present invention, in which a large number of large-diameter holes 1 are formed on a plate member 4.
And the small-diameter holes 2 are formed in a pattern.
That is, the plate member 4 is divided into four substantially equal parts, and a large number of large-diameter holes 1 and small-diameter holes 2 are formed only in the upper left part and the lower right part. The upper right portion and the lower left portion are blank portions 3. The first figure portion 5 in the upper left portion is provided with large-diameter holes 1 at equal intervals centered on positions corresponding to the intersections of the grid. That is, the large diameter hole 1 is bored at each intersection of the unit lengths in the X and Y directions of the first orthogonal coordinate system 1a indicated by XY. Next, the small-diameter holes 2 are provided at the intersections of the grid-shaped second orthogonal coordinate system 2a having intersections at half positions of the X-direction unit length and the Y-direction unit length of the first orthogonal coordinate system 1a. The small-diameter hole 2 is penetrated only in the upper right part of the first graphic portion 5 with the chain line A as a boundary, and in the second graphic part 6 only in the upper left part of the chain line B.

The punching plate 7 as described above is manufactured, for example, as follows. By pressing the strip-shaped metal plate sequentially, the minimum pitch of the large-diameter holes 1 or the small-diameter holes 2
It is controlled so that it is sequentially sent in the longitudinal direction by 1/2. As the lower mold of the press, there is used one in which a plurality of rows of holes matching the large diameter holes 1 and the small diameter holes 2 are penetrated. The upper die has the same number of large-diameter hole punching pins and the same number of small-diameter hole punching pins as the lower die. The large-diameter hole pin and the small-diameter hole pin are configured to be able to move in and out of the lower surface of the upper mold, and the large-diameter hole 1 pin and the small-diameter hole 2 pin are respectively the control device and the device. Is connected to an air pressure or hydraulic device driven by, and those pins are controlled so that they can freely move in and out by appropriate tamming. That is, a control program is created so that a desired perforation pattern is formed, and the large-diameter holes 1 and the small-diameter holes 2 are punched at required positions of the plate material 4 according to the program. for that reason,
Protruding those necessary pins at each timing,
The plate member 4 may be sequentially and intermittently moved in the longitudinal direction while controlling the unnecessary pins so as not to project.

Next, FIG. 2 shows a second embodiment of the punching plate 7 of the present invention. In this embodiment, the first figure portion 5 formed by the large diameter hole 1 of the black circle on the elongated plate member 4 made of aluminum.
And a second figure portion 6 formed by a small-diameter hole 2 of a black circle and a blank portion 3 where they do not exist, which represent a cloud floating in two types of sky and a seagull against it. That is, a blank part 3 in the shape of a seagull is represented in the first graphic part 5, and two types of clouds are represented by the first graphic part of the large diameter hole 1 and the second graphic part of the small diameter hole 2, and
The four edges of the plate member 4 are bordered by blank portions. The presence of this edge causes the figure to become cohesive. Further, this edge portion can be used as a mounting portion to be mounted on the supporting material of the punching plate. Further, by bending the edge portion into an L-shaped cross section or the like, the punching plate can be prevented from being deformed. The punching plate 7 of this embodiment is used as a side wall plate arranged on a fence or balustrade of a bridge. Alternatively, it can be used for decorating a wall surface provided with illumination on the back side. It should be noted that the blank portion 3 in which no hole is provided can be printed.

[0008]

In the punching decorative plate of the present invention, the large-diameter holes 1 are bored only on the plate member 4 at a large number of selected positions of the first orthogonal coordinate system 1a, and the second orthogonal coordinate system 2a is selected. The small-diameter holes 2 are drilled only at a large number of positions that are
The figure part where only a large number of large-diameter holes 1 exist, and at least that part
A large number of small holes 2 are provided at positions adjacent to the outer edge of the graphic portion of the large hole 1.
And the large-diameter hole 1 are mixed, and the large-diameter hole 1 is also a small-diameter hole.
By the three parts of the blank part 3 where 2 does not exist at all
The decoration such as unified characters and figures was constructed as a whole
Things. Therefore, it is possible to clearly express a figure or the like depending on the change . Especially, large diameter hole 1 and small diameter hole 2 are mixed.
In the part to
A high-quality decorative expression with a clear ratio is displayed. Further, since the large-diameter holes 1 and the small-diameter holes 2 are formed at positions where the drilling positions are different by a half pitch, the holes do not interfere with each other, and a large number of large-diameter holes 1 and small-diameter holes 2 are mixed. The total hole area per unit area becomes large in the portion to be opened, the background of the punching decorative plate can be more clearly recognized, and the portion having only the large diameter hole 1 or the empty portion 3 gives different impressions. Therefore, it is possible to provide useful decorative plates as various decorative plates. Further, since the large-diameter holes 1 and the small-diameter holes 2 are formed at positions where the drilling positions are different by a half pitch, mass production is possible with a processing machine having a large number of punching pins that can freely move in and out.
