For example, the magnets 25, 25 ', 26, 26', 27, 27 'of the upper plate 21 are N poles, and the magnets 35, 35', 36, 36 ', 37 of the lower plate 31 are , 37 ') may be disposed as the S pole, furthermore, the magnets indicated as 25, 25', 27, 27 'of the upper plate may be arranged as the N pole, and the magnets indicated as 26, 26' as the S pole. Correspondingly, the magnets indicated by 35, 35 ', 37, 37' of the lower plate are preferably S poles, and the magnets indicated by 36, 36 'are N poles. That is, it is satisfied if the magnets corresponding to the upper plate 21 and the lower plate 31 have opposite polarities so that the attraction force can act on each other.

Referring to FIG. 4, the punching member 10 has punching blades 12 and 13 having a pattern of a specific pattern on the lower portion of the pressure plate 11. Naturally, the patterns of the punching blades 12 and 13 may be varied. In addition, two guide blades 14 are further formed separately from the punching blades 12 and 13. The guide blade 14 is formed to have a greater height (length) than the punching blades 12 and 13. When the pressure plate is pressed, the guide blades 14 first pass through the guide holes 24 before the punching blades 12 and 13 having the pattern of the specific pattern pass through the guide holes 23 and punch the sheet. While the punching blades 12 and 13, the guide hole 23 and the punching hole 33 are positioned on the same line. In addition, it can be seen that the punching blade 13 is provided with a guide protrusion 13a extending downward in the lower end thereof. Similarly to the guide blade 14, the guide protrusion 13a is punched while the guide protrusion 13a first passes through the guide hole 23 before the punching blades 12 and 13 pass through the guide hole 23. The blades 12 and 13, the guide hole 23 and the punching hole 33 serves to position the same line. Here, the guide protrusion 13a is formed at the end of the punching blade 13 so that the shape of the guide protrusion 13a is not punched in the punched sheet. However, since the guide blade 14 is formed separately from the punching blades 12 and 13, the guide blade 14 is also punched in the shape of the guide blade 14. Therefore, it is preferable to design the position and shape of the guide blade 14 so that the punching part (shape) by the guide blade 14 can be matched with the punching area (shape) by the punching blades 12 and 13. Do.

Referring to FIG. 5A, the upper jig 22 is coupled to the center of the upper plate 21. The upper jig 22 has four spring holders 29 protruding from all four sides thereof, as described above. The guide hole 23 cut in the same shape as the pattern of the punching blades 12 and 13 is formed. By forming the guide hole 23 in the same shape as the pattern, that is, the punching blades 12 and 13 pass through the guide hole 23, so that the punching blades 12 and 13 are brought into position. Guided to be aligned.

Referring to FIG. 5B, the upper plate 21 is not provided with an upper jig 22 having guide holes 23 having the same shape as the patterns of the punching blades 12 and 13. Instead, the guide hole 24 'is formed in the center of the upper plate 21 so that the incision 23' and the guide blade 14 can pass through the punching blades 12 and 13. It can be seen that. This is sufficient to guide the punching blades 12 and 13 by the guide blades 14 and the guide holes 24 ', so that the upper jig 22 having the guide holes 23 is not provided separately as shown in FIG. 5A. No. However, four spring holders 29 'are equally provided.

6A and 6B, the operation of the present invention will be described in detail.

First, the sheet 40 is placed on the lower plate 31. According to the present invention, since the upper plate 21 and the lower plate 31 are separated from each other, the punching position of the sheet 40 is not limited. That is, punching is possible not only at the edge of the sheet 40 but also at the center or any place, and it is necessary to find a desired position and place it on the lower plate 31.

When the sheet 40 is not a transparent material, it is problematic to align the punching blades 12 and 13, the guide holes 23, and the punching holes 33 on the same line. In particular, since the punching blades 12 and 13 and the guide hole 23 are already coupled, there is no problem, but the alignment of the punching blades 12 and 13 and the punching hole 33 is particularly problematic. For this purpose, the upper plate 21 should be placed in the correct position on the lower plate 31. Specifically, the punching hole 33 of the lower plate 31 and the guide hole 23 of the upper plate 21 should be located on the same line, and likewise the guide hole 34 of the lower plate 31 The guide holes 24 of the upper plate 21 should be aligned so that they are located on the same line. According to the present invention, a predetermined position of the seat 40 is placed on the lower plate 31 by a magnet formed on each of the upper plate 21 and the lower plate 31, and the upper plate 21 in the state. If it is placed, it is automatically aligned by the attraction force and the repulsive force of the magnets 26 and 36 at the corresponding positions, respectively. When the magnets 26 and 36 are multipole magnets, the accuracy of alignment is further improved.

When the pressing plate 11 of the punching member 10 is pressed downward in the aligned state, before the punching blades 12 and 13 pass through the guide hole 23 and pass through the punching hole 33. The guide protrusion 13a protruding from the lower portion of the guide protrusion 13a passes through the guide hole 23 and the punching hole 33 to finely adjust the guide. In addition, the guide blade 14 passes through the guide holes 24 and 34 to guide the punching blades 12 and 13 as well.

However, there is a limit in the alignment by the magnets 26 and 36, so that there is an error. In order to solve this problem, in the present invention, it can be seen that the guide hole 34 formed in the lower jig 32 has a tapered surface 34a inclined outward at an upper end thereof (see enlarged view of FIG. 6A). The tapered surface 34a is for correcting the case where the guide blade 14 and the guide hole 34 of the lower jig are not positioned on the same vertical line due to the error after alignment by the magnet.

That is, even if there is an error in alignment by the magnets 26 and 36, the guide blade 14 slides along the tapered surface 34a, so that punching is possible while making fine adjustments.

The punching blades 12 and 13 finely adjusted and guided by the above-described guide protrusion 13a and guide blade 14 pass through the guide hole 23 of the upper jig 22 and punch the sheet. On the other hand, the punching blade (12, 13), the guide blade 14 and the guide protrusion (13a) is formed as a blade end to facilitate cutting as shown.

According to the present invention, there is an effect that can be punched freely in a desired position, regardless of the punching position, such as the sheet to be punched.

In particular, a plurality of magnets are attached to the upper plate and the lower plate, respectively, at positions opposite to each other, so that the magnets can be accurately aligned to the correct positions of the upper plate and the lower plate.

In addition, by forming a guide blade separately from the punching blade to the punching member or by adding a guide protrusion to the punching blade, there is an effect to be finely adjusted by leading and guiding during punching after primary alignment by the magnet.

In addition, by providing an alignment portion on one side of the lower plate, there is an effect that can be continuously punched without breaking or overlapping a pattern of a specific pattern that the punching member has.

In addition, since the upper jig and / or the lower jig is formed to be detachable, when the pattern of the punching member is changed, the upper jig and / or the lower jig may be replaced with a corresponding one so that the compatibility of the product is high.

In addition, by making the magnet a multi-pole magnet, the alignment accuracy due to the attraction and repulsion of these magnets is increased.

In particular, since the guide blade penetrates the guide hole of the lower jig along the tapered surface, fine alignment is possible in addition to the alignment by the magnet.
