ようとするものである。However, in all of those described in the prior art, the cutting edge has a sharp knife pointed shape, so that there is a problem that the blade is easily chipped during cutting.
In addition, it is possible to provide a relatively large number of cutting blades, but on the other hand, the cutting edges are sharp and the number of blades is large, so high-frequency shocking cutting noise is likely to be generated and the working environment is deteriorated due to the noise. was there. In addition, re-polishing involves polishing the cutting edge on the back side of the cutter body blade, so the thickness of the cutter changes and becomes thin with each re-polishing, and the cutting position on the work material changes. Fine adjustment of the blade position was indispensable. In addition, this fine adjustment is a work requiring considerable skill, and often causes the blade tip to strike the press roller or the like mounted overhanging the cutter on the processing machine main body to cause chipping, which greatly impairs workability. In addition, there is a problem that costs such as blade repair costs are also expensive. SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and aims at hardly chipping the blade, can quickly repair even the chipped chip, has a small cutting noise, and requires re-polishing. It is an object of the present invention to provide a replaceable cutter in which the thickness of the cutter hardly changes.

The blade is a single-blade slitter knife and can change the cutting blade position by rotating about an axis perpendicular to the mounting seat. A part of the blade edge protrudes from the outer circumference of the cutter body, and the blade back surface is a cutter. It is positioned and fixed by mechanical means so as to slightly protrude from the side surface of the main body in the direction of the cutter rotation axis. Since a single-blade type slitter knife-like replacement blade, whose cutting blade position can be changed by turning, is used, the number of blades is reduced as compared with the conventional number of blades, but the strength of the cutting blade is increased, and chipping and cutting noise can be suppressed. In addition, since the cutting edge position can be changed by turning indexing based on the hole where the replacement blade is installed, even if chipping occurs, it can be repaired quickly, one blade can be used many times, and the number of regrinds can be reduced And a longer life is possible. Furthermore, the re-polishing of the replacement blade is performed by polishing the resilient surface instead of the back surface of the blade, so if the replacement blade after re-polishing is attached to the cutter body, the cutter thickness hardly changes, so there is no need for fine adjustment of cutter installation.

決め廻り止めピン１２が嵌入されている。A plurality of replacement blade mounting seats 11a are formed at equal angular positions (although not necessarily equal angles) on the same circumference on the side surface orthogonal to the rotation axis of the cutter body 11.
The replacement blade mounting seat 11a has a substantially circular shape with a cutout of approximately 1/4. The bottom surface has a two-stage counterbore that is concentrically deeper at the center by one step. The seating surface is slightly shallower than the thickness of the replacement blade. The back surface of the replacement blade is formed so as to be recessed from the side surface 11b of the cutter body and slightly inclined for about 30 minutes with respect to a surface perpendicular to the axis of rotation of the cutter in a direction having a positive set angle θ. At the center of the counterbore circle, a tapped hole 11c is screwed at right angles to the mounting seat surface of the replacement blade tip. Inconsistency in the distance between the two-stage replacement blade mounting seat and the tapped hole from the center of the cutter body is related to the unevenness of the positions of the cutting edges of the cutter, and therefore requires special care in processing. A tap hole 11c is formed in the seat surface of the replacement blade mounting seat 11a.
A pin hole 11d is formed on a diameter line passing through the hole, and a positioning detent pin 12 is fitted therein.

る。The replacement blade tip 13 mounted on the replacement blade mounting seat 11a has a diameter slightly larger than the diameter of the mounting seat and a part of which projects as a cutting blade from the outer periphery of the cutter body. The blade has a single-blade slitter knife shape with a cross-sectional shape like a half, and has a boss portion on the front side of the blade that comes into contact with the mounting seat surface and serves as a reference surface. At the center, a 90-degree chamfered through hole is drilled, and the 90-degree chamfered surface 13a serves as a reference hole for turning the spare blade, and the spare blade 13 turns to change the cutting blade position based on this hole. Will be A hole 13b, into which the positioning detent pin 12 is fitted, is formed outside the countersunk surface 13a, at an equiangular position on the same circumference concentric with the countersunk surface, and in this example at an equal angular position of eight. The ridgeline 13f of the outer peripheral line of the single blade type slitter knife of the replacement blade 13 is a cutting edge line. Since the circular blade is a cutting blade that cuts at a small inclination angle with respect to the tangential direction of the cutter rotating circle, the wedge angle at the cutting position of the cutting blade is
And becomes a sharper cutting edge.

数の替刃の外周精度がそろい易い。The perpendicularity of the bottom surface 13c serving as the reference surface of the boss portion and the parallelism between the bottom surface 13c and the blade back surface 13d with respect to the 90-degree plate surface 13a are important. If changed, it affects the stability of the cutting edge line. Blade is a cemented carbide, chromium nitride comprising a mixed hard cutting material or surpass surface 13e, CrN on at least any one side of the blade back rake surface 13d or Cr 2 N or CrN and Cr 2 N, such as high-speed tool steel It is desirable to use a hard cutting edge material that has been subjected to a wear-resistant surface treatment such as coating the material layer to a thickness of 0.5 to 6.0 μm. The replacement blade 13 thus formed is positioned and prevented from rotating by the pin 12 and the cutter body 1 is rotated.
The blade 1 is fastened to the spare blade mounting surface with a countersunk machine screw 14. In this example, the 90-degree plate surface 13a serves as a positioning reference hole when the replacement blade is mounted. However, the inner periphery of the second counterbore portion of the replacement blade mounting seat 11a of the cutter body and the outer periphery of the boss portion of the replacement blade are provided. If the portion 13g is fitted over almost the entire circumference, the outer peripheral portion of the boss portion becomes a positioning reference when the spare blade is attached when the spare blade is attached, and the outer peripheral accuracy of the plurality of spare blades is easily uniform.

えて研磨する必要がある。After the replacement blade 13 is fastened to the entire replacement blade mounting seat 11a of the cutter body 11 with a flat head screw 14, the cutter is attached to the processing machine and the spine cover to be bound is trimmed. When the number of cuts increases and the sharpness decreases, countersunk screw 1
Loosen the blade 4, slightly lift the blade, remove it from the pin 12, rotate the blade 13 by one pitch to change it to a new cutting blade, and fit the pin 12 to the blade again and fix it. In this way, the blade 13 is turned, and when the blade is performed eight times, the blade 13 needs to be polished again. Remove the replacement blade 13 and turn it into a rod-shaped jig having a diameter slightly smaller than the diameter of the replacement blade, the squareness of the mounting surface of the replacement blade with respect to the rotation axis being accurate, and having a boss at the center that fits into the through hole of the replacement blade. The fixing bolt is screwed into the center hole of the jig and fixed by contacting the back surface of the blade. Then, the jig is rotated about the rotation axis, and the grindstone surface is polished with a flat grindstone having a blade surface parallel to the cutting surface 13e. By polishing in this way, the cutting edge 13
f is formed concentrically with the spare blade center axis on a plane perpendicular to the spare blade center axis. Further, since the replacement blade 13 repolishes the resilient surface 13e, the thickness of the replacement blade hardly changes. However, the diameters of all the replacement blades of at least one cutter need to be uniform and polished so as to have the same size.

In the second embodiment, a single-blade slitter knife-shaped replacement blade having a polygonal shape such as a regular square, a regular pentagon, or a regular hexagon instead of a circle is used. In the embodiment, a regular hexagonal replacement blade is illustrated. Spare blade 15
Has a regular hexagonal outer edge cutting edge, no pin hole for detent, and a boss 15a on the front side of the blade forms a regular hexagonal shape along the cutting edge 15b. The replacement blade mounting seat 11e of the cutter body is provided with a width slightly larger than the width of two opposing parallel sides of the regular hexagon of the boss 15a, and the boss 15a plays a role of preventing rotation during cutting.

の１と同じである。The reference hole of the center 90-degree dish 15c is the same as that of the first embodiment. In this example, the cutting edge ridge is formed on the entire outer edge, but may not necessarily be formed on the entire outer edge, but may be formed at equal intervals. When changing the position of the cutting blade by turning the spare blade due to reduced sharpness during cutting, loosen the countersunk screw, slightly lift the spare blade, remove the spare blade boss from the replacement blade mounting seat, and rotate one pitch, then renew. Fit the regular hexagonal part of the spare blade boss into the detent seat and tighten the flat head screw. In the re-polishing, polishing the surviving surface 15d is described in Example 1
However, the rod-shaped polishing jig performs indexing grinding at a predetermined angle sequentially without rotating the grindstone while keeping the cutting depth of the grindstone constant. It is convenient to use a polishing machine of a machine capable of rotating and indexing the jig rotation axis. The blade material and wear-resistant surface treatment are also the same as those in the first embodiment.

の大幅な低減に寄与する。Since the replacement blade is constructed as described above, the replacement blade type cutter according to claim 1 has a smaller number of blades as compared with the conventional blade and has a small inclination angle with respect to the tangential direction of the cutter rotation. Therefore, high frequency shocking cutting noise caused by a large number of blades is suppressed. Also, after re-polishing the spare blade,
Even when the spare blade is attached to the cutter body, the thickness of the cutter hardly changes, so that fine adjustment at the time of attaching the cutter is unnecessary and skill is not required. For this reason, even a young worker can easily exchange and re-grind the work, thereby improving work efficiency. In addition, it is difficult for chipping to occur, and even if chipping occurs, it can be repaired quickly, and one cutting edge tip is used more frequently than conventional ones. As a result, the cut skin is hardly deteriorated and the life can be extended, contributing to a significant reduction in running costs.

て、良い作業環境が得られる。According to the second aspect of the present invention, the rotation indexing of the spare blade can be accurately and easily performed. In the spare blade type cutter according to the third aspect, since the entire back surface of the spare blade is prevented from being brought into contact friction with the work material, heat generation is reduced, and the life is hardly deteriorated,
It contributes to prolonging the service life, and a stable setting angle can be obtained by keeping the parallelism between the blade back surface and the blade surface. The spare blade type cutter according to claim 4 reduces the entrapment of air during rotation,
There is little contact with floating chips and the scattering of paper dust is suppressed, and a good working environment can be obtained.
