Abstract

PROBLEM TO BE SOLVED: To quickly manufacture a large size of punched perforated plate using a small number of punches by intermittently transferring a plate stock by a prescribed length in the longitudinal and lateral direction and selectively lowering punches. SOLUTION: The juxtaposed direction (X-axis direction) of punches 3 and 4 is parted into rows (a), (b), (c), (d), (e) and (f), and the process transferring a plate stock 1 successively in the direction (Y-axis direction) perpendicular to the X-axis direction is previously calculated. For example, the row (f) is transferred in the Y-axis direction as the first process, the row (e) is transferred in the right direction along the Y-axis as the second process, and the row (d) is transferred in the left direction along the Y-axis as the third process. Here, the plate stock 1 is inverted in the Y-axis direction, the row (c) is transferred in the left direction along the Y-axis as the fourth process, the row (b) is transferred in the right direction along the Y-axis as the fifth process, and finally the row (a) is transferred in the left direction along the Y-axis as the sixth process. And control signals are transmitted to punches 3, 4, and the transfer inverting mechanism of the plate stock 1, so that the prescribed punching is performed, whereby, the punched perforated plate arranged prescribed pictures is formed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a punched perforated plate, and more particularly to a punched perforated plate in which a large number of holes are formed at desired positions so that characters, images, and other various patterns are revealed. The present invention relates to a method for manufacturing a plate.

[0002]

2. Description of the Related Art Conventionally, a punched perforated plate is known in which a large number of punched holes are formed at predetermined positions of a material plate such as metal or synthetic resin so that characters, images, and other various patterns are exposed. It is used in a wide range of fields such as soundproof walls for roads and railways, speaker nets for audio equipment, interior materials for buildings, and even outdoor and indoor equipment such as trash cans and fences.

As a means for producing these punched perforated plates, Japanese Patent Application No. 2-331836 (JP-A-4-200).
No. 824) is known.

As shown in FIG. 8, this punching perforated plate manufacturing means intermittently feeds a long raw material plate 1 in the longitudinal direction by a predetermined length, and at the same time, feeds the raw material plate 1 to a predetermined length. When the above operation is performed, a large number of punch punches 2 arranged in a direction intersecting the longitudinal direction of the blank 1 are selectively lowered to form holes.

According to this conventional manufacturing method, it is possible to manufacture punched perforated plates having various patterns.

However, according to the above-mentioned conventional method for manufacturing a punched perforated plate, a press machine in which punching punches 2 are arranged in parallel by the number of punching holes formed in the material plate 1 in the lateral direction is required. .

Therefore, if the width L ₁ in the lateral direction is narrow, there is no problem of difference, but if the width L ₁ is wide,
A press machine having a large number of punching punches 2 arranged side by side has a wide width L ₂ , which requires not only a large and vast installation place and working space but also is expensive. There is a problem that it is extremely difficult to manufacture.

[0008]

SUMMARY OF THE INVENTION The problem to be solved by the present invention is that it requires a vast installation place and working space in order to manufacture a large punched perforated plate by the conventional method for manufacturing a punched perforated plate. Or, it requires a high-priced press machine.

[0009]

DISCLOSURE OF THE INVENTION The present invention provides a blank plate arranged in a direction orthogonal to at least one punch punch.
When an operation of intermittently feeding the material plate by a predetermined length in the front-back and left-right directions is performed, and the predetermined operation is performed on the material plate,
The operation of selectively lowering the punch punch is repeated.

The blank plate is intermittently fed to the punch punch by a predetermined length in the front-rear direction and the left-right direction, and when the hole forming position of the blank plate coincides with the punch punch, the punch punch is lowered to form the hole. The operation of forming is repeated.

Embodiments of the present invention will now be described with reference to the drawings.

2 to 4 show a control signal for use in the present invention in which punching characters 2 of alphabetic characters A and B are sent from an electronic controller to a horizontally long rectangular plate 1 as shown in FIG. 1, for example. Two conventionally known punch punches 3, which are driven by
4 shows an embodiment in the case of forming a punched perforated plate by 4.

In the present embodiment, the design of the punched character 2 is read by a reading device (not shown), and as shown in FIG. 2, punching data of punching punches 3 and 4 (black circles are punched in the drawing). The part and white circle indicate the non-punching part.).

Particularly, in the present embodiment, the punch punches 3, 4 are used.
Of the columns a, b, c, d,
The process of sequentially moving the material plate 1 in the direction perpendicular to the X-axis direction (Y-axis direction) divided into e and f is calculated in advance.

The order and the transfer direction are preferably such that the punching work can be performed most efficiently. For example, in the present embodiment, as shown in FIG. 3, the column f is the left direction of the Y axis in the figure as the first step. The column e is transferred to the Y-axis right direction in the figure as the second step, and the column d is transferred to the Y-axis left direction in the figure as the third step, in which the blank 1 is inverted in the Y-axis direction. Then, the column c is transferred to the Y-axis left direction in the figure as the fourth step, the column b is transferred to the Y-axis right and left direction in the figure as the fifth step, and finally the column a is moved to the Y-axis left in the figure as the sixth step. Transfer in the direction.

The control signal is punched out by punches 3, 4
In addition, the material is sent to a transfer / reversal mechanism (not shown) of the material plate 1 to perform a predetermined punching process to form a punched perforated plate having a predetermined design.

According to this embodiment, it is possible to rapidly form a punched perforated plate in which a pattern is formed by a large number of perforations by using the two punching punches 3 and 4.

Therefore, a large punching machine is not required and a vast installation place is not required.

FIGS. 5 and 6 show different embodiments of the present invention. In the above embodiment, two punching punches 3 and 4 are used, and these punching punches 3 and 4 are always used. , 5 as a unit for punching, the present embodiment punches three punches 3, 4, 5 as a unit.

The control means in this embodiment is the same as that in the above-mentioned embodiment, but when the two punches are used, it is necessary to move 6 times in the Y-axis direction. If 3 punches are used for 4 times,
Further, the working time can be shortened.

In each of the embodiments, the operation of moving the column formed in the Y-axis direction in the figure as one unit and moving the column in the X-axis direction in the figure is repeated, but the present invention is not limited to this. The movement in the axial direction and the movement in the X-axis direction in the drawing may be appropriately combined.

Further, in the above-mentioned embodiment, a plurality of punching punches are used, and a plurality of perforations can be formed at one stop position of the material plate 1 at a time, which is excellent in working efficiency. , At least one punch is necessary.

[0023]

According to the present invention, a large punched perforated plate can be rapidly manufactured using a small number of punches.

Therefore, a large press machine is not required,
It is economically advantageous, and since it is not necessary to install a large press machine, it does not require an installation area.
