[0002]
[Prior art]
2. Description of the Related Art Conventionally, various punching devices have been used as devices for forming holes of a predetermined shape in a thin plate member such as a wiring board, a film, and a metal foil. In this punching device, a thin plate-shaped member is interposed between a die and a punch, and the punch is fitted into a hole of the die through the thin plate-shaped member to form a hole in the member. In such a punching device, in particular, in the case where holes having various shapes or sizes such as round, square, and elliptical are formed in one thin plate-like member, the punch and the die do not need to be replaced. There is disclosed a punching device that can easily cope with a change in the punching pattern (Japanese Patent Publication No. 8-398).
[0003]
FIG. 4 is a perspective view partially showing a conventional punching device. Dies 26a, 26b and 26c having holes are fixed to the upper surface of the lower side end 24b of the plurality of U-shaped support members 24.
[0004]
Further, a hole (not shown) penetrating from the upper surface to the lower surface is provided in the upper side end 24a of the support member 24, and the punch head 25 is fixed on the upper side end 24a. In the punch head 25, a cylinder (not shown) is arranged with a piston (not shown) facing downward. A punch support (not shown) is fixed to the lower end of the piston, and the punches 27a, 27b, and 27c are supported by the punch support. The punches 27a, 27b and 27c pass through holes formed in the upper side end 24a of the support member, and move closer to and away from the dies 26a, 26b and 26c by elevating and lowering the piston.
[0005]
The tips of the punches 27a, 27b and 27c are machined into different shapes according to the required perforation shape, and the dies 26a, 26b and 26c have holes each having a shape corresponding to the corresponding punch. are doing. For example, the tip of the punch 27a is formed in a circular shape, the tip of the punch 27b is formed in an elliptical shape, and the tip of the punch 27c is formed in a square shape. Then, a plurality of punching units 29 composed of the support member 24, punches, dies, and the like are arranged and fixed on the base 21.
[0006]
When piercing a thin plate member using such a piercing device, first, the position of the thin plate member is controlled in accordance with a preset program, and the position where the round hole is to be formed is arranged below the punch 27a. Thereafter, the punch 27a is lowered, and the punch 27a is fitted into the hole of the die 26a via the thin plate member, thereby forming a round hole in the thin plate member. This operation is repeated to form all round holes in the thin plate member.
[0007]
Next, the position where the oval hole is to be formed in the thin plate member is arranged below the punch 27b, the punch 27b is lowered, and the oval hole is formed in the thin plate member by fitting into the hole of the die 26b. This operation is repeated to form all the elliptical holes in the thin plate member. Similarly, all the square holes in the thin plate member are formed by the punch 27c and the die 26c.
[0008]
As described above, when the punching device shown in FIG. 4 is used, it is not necessary to change the types and positions of the punch and the die according to the change of the punching pattern. A plurality of holes having various shapes such as an oval can be efficiently formed.
[0009]
By the way, for example, in the case of manufacturing a wiring board, a plurality of modules may be formed from a thin plate-like member that becomes one board. FIG. 5 is a plan view showing the punching positions of the thin plate member when a plurality of modules are formed. As shown in FIG. 5, when a plurality of modules 31 are taken from one sheet-like member 9, the hole patterns of the holes 31 a in each module 31 are all the same. Therefore, if the holes of the plurality of modules 31 can be formed at the same time, the perforation process becomes easy and the time can be shortened.
[0010]
Then, using the punching device shown in FIG. 4, for example, after replacing the punches 27a, 27b and 27c and the dies 26a, 26b and 26c with punches and dies of the same shape, the thin plate member 9 is moved to a desired position. When the plurality of punches are arranged and lowered simultaneously by the piston, holes having the same shape can be formed at predetermined intervals. Then, by repeating the process of moving the position of the thin plate member 9 and perforating the same, holes having the same pattern can be formed in the plurality of modules 31 at the same time.
[0011]
[Problems to be solved by the invention]
However, when the size of the module 31 is changed and the interval between adjacent modules changes, the interval between punches also needs to be changed correspondingly. However, when the punching device shown in FIG. Since 29 is fixed to the base 21, it is difficult to change the interval between the units 29. Further, when the interval between the punching units is adjusted and fixed again, the operation becomes extremely complicated.
[0012]
As described above, in the conventional punching apparatus, when a plurality of holes are formed at the same time, the distance between the holes cannot be adjusted, and the distance between the dies and the distance between the punches can be easily changed. Could not be adapted. Further, every time the interval (pitch) between adjacent modules is changed, it is necessary to adjust the interval between dies and between punches, so that it has been difficult to maintain pitch accuracy.
[0013]
The present invention has been made in view of such a problem, and when a plurality of holes are simultaneously formed in a thin plate member, the distance between the holes can be easily changed, and the holes can be formed with high precision. It is an object of the present invention to provide a multi-axial drilling device for a thin plate member capable of drilling a hole.
