Description

[Detailed Description of the Invention] This invention relates to a cutting device that cuts a band-shaped blade plate into predetermined dimensions.

When using a Thomson (punching device) to punch cardboard or other thick paper into a predetermined shape, it is necessary to place the cut blade plate into the punched shape. I have to.

Here, the above-mentioned cutting device will be explained with reference to FIGS. 1 to 3 of the attached drawings. A leg body 2 is provided perpendicularly to the end of a support table 1 that supports a band-shaped blade plate. A blade holder arm 4 is swingably supported by a support piece 3 that stands up from one end.
The U-shaped end of the operating lever 7 is swingably supported via a pin 6 on a support piece 5 that stands up from the other end of the leg 2, and the end of the operating lever 7 and the cutter holder arm 4 are connected to each other. The ends are connected by a U-shaped link 8, so that when the operating lever 7 swings in the direction of the arrow in FIG. 1, the cutter holder arm 4 swings downward. Then, the fixed cutter 9 is attached to the end of the support table 1, while the cutter holder arm 4
A movable cutter 10 is attached to the movable cutter 10, and this movable cutter 10 corresponds to the fixed cutter 9.

To cut a band-shaped blade plate using such a cutting device, place the band-shaped blade plate on the support table 1, and move the movable blade 10 by swinging the operating lever 7 in the direction of the arrow in FIG. Lower this movable blade 10
The band-shaped blade plate is cut to size using the fixed blade 9 and the fixed blade 9.

By the way, there are two ways to cut the blade plate to size: one is to cut a band-shaped piece to a set length, and the other is to bend the band-shaped blade plate A into an L-shape and cut the bent piece B to size, as shown in Fig. 5. However, cutting the latter method has traditionally been very time-consuming.

That is, to cut the bent piece B, the bent piece B is placed on the support table 1, and a plate-shaped plate for regulating the cutting dimension is placed between the band-shaped blade plate A standing up on the table and the movable blade 10. Since the movable cutter 10 is moved downwards to regulate the cutting position, when forming a large number of L-shaped blade plates with the same length dimension of the bent piece B, the plate body for regulating the cutting dimension is It is necessary to align the folded piece B along the movable blade 9 each time the folded piece B is cut, which has the drawback of poor cutting workability.

The object of this invention is to solve the above-mentioned drawbacks and to provide a cutting device that can efficiently cut a large number of L-shaped blade plates having the same length of bent pieces.

In order to achieve the above object, this invention forms a vertically long guide groove on the surface of the movable cutter, and this guide groove has a wide groove at the back of the narrow groove so that the horizontal cut can be made by T. The width of the upper part of the guide groove is larger than that of the lower part, and the cutting dimension regulating plate is removably attached to the surface of the movable blade. A shaft is provided, a retaining plate is formed at the end of the engagement shaft that can fit into the wide groove above the guide groove, and a dimension regulating plate is attached to the surface of the movable cutter to fix it to the movable cutter. The bent piece of the L-shaped belt-shaped blade plate is cut using a knife.

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

As shown in FIGS. 3 and 4, a vertically elongated guide groove 11 is formed on the surface of the movable cutter 10 attached to the cutter holder arm 4, extending from the upper end of the movable cutter 10 to the center. This guide groove 11 is formed by forming a wide groove part 13 at the back of a narrow groove part 12 and cutting it in the transverse direction into a T-shape. This is an insertion port 14.

An engagement shaft portion 16 is provided on the upper back surface of the cutting dimension regulating plate attached to the surface of the movable cutter 10.
A retaining plate 17 having a larger diameter than the engaging shaft 16 is formed at the end of the engaging shaft 16 . The engagement shaft portion 16 is formed in a size that allows it to move freely along the narrow groove portion 12 of the guide groove 11, while the retaining plate 17 is movable along the wide groove portion 13 of the guide groove 11, and has a size that allows it to move freely along the narrow groove portion 12 of the guide groove 11. It is formed to a size that makes it difficult to escape.

Now, when the retaining plate 17 of the cutting dimension regulating plate 15 is inserted into the insertion opening 14 at the upper part of the narrow groove part 12 and positioned in the wide groove part 13, and then moved downward, the engagement shaft part 16 is inserted into the guide groove. 11, and the retaining plate 17 descends along the narrow groove portion 12 of the wide groove portion 1.
3, the retaining plate 17 comes into contact with the bottom of the guide groove 11, and as shown in FIG. 3, the cutting dimension regulating plate 15 can be attached to the surface of the movable cutter 10.

Therefore, the bent piece B of the L-shaped belt-shaped blade plate A shown in FIG. When the movable cutter 10 is lowered by swinging the operating lever 7, the bent piece 2 can be cut to a length corresponding to the thickness of the cutting dimension regulating plate 15.

A large number of cutting dimension regulating plates 15 having different thickness dimensions are prepared, and the cutting dimension regulating plates necessary for the cutting operation are attached to the movable blade 10. Further, the length of the regulating plate 15 is arbitrary.

Since the cutting dimension regulating plate 15 is attached to the movable cutter 10 so that it can be raised and lowered, the bent piece B
When the lower end of the cutting dimension regulating plate 15 comes into contact with the bent piece B and stops during cutting, the movable blade 1
0 is lowered to the cutting completion position and the movable blade 10
There is no possibility that the cutting size regulating plate 15 and the cutting size regulating plate 15 move relative to each other, thereby interfering with the cutting operation.

As described above, in this invention, by bringing the L-shaped belt-shaped blade plate into contact with the cutting dimension regulating plate attached to the movable blade and lowering the movable blade, the bent piece of the belt-shaped blade plate is cut by the thickness of the cutting dimension regulating plate. Since it can be cut to a length corresponding to the dimensions, it is possible to efficiently cut a large number of L-shaped blade plates with the same length dimension of the bent pieces.

In addition, since the cutting dimension regulating plate is removable from the movable blade, the cutting dimension of the bending plate can be changed arbitrarily by preparing and replacing many types of cutting dimension regulating plates with different thickness dimensions. can.
