Abstract

PURPOSE:To increase mounting stability by forming a second cutting blade in the ark shape formed at a corner part with an acute angle of a vertical face in the parallelogram shape so that a tangent line at an end part on the short side of the vertical face and a ridge line on the short side make an angle less than 180 degrees. CONSTITUTION:A second cutting blade 31 in the ark shape formed at a corner part with an acute angle of a vertical face in the parallelogram shape is formed so that a tangent line L at an end part P on the short side of the vertical face and a ridge line 32 on the short side make an angle less than 180 degree. Due to this, the area of a contact face 40 formed between the ridge line 32 on the short side can be secured large, the mounting stability is increased and the effective blade length of the cutting blade on the long side can be set longer.

However, in the above-mentioned pin mirror cutter, the conventional tip 1 has a parallelogram shape, and the arc-shaped second cutting edge 5 is further provided.
However, since the tangent lines at both ends coincide with the ridge lines on the long side and the short side to form a smoothly continuous arc curve, as shown in FIG. Since G 2 becomes short, a sufficient area cannot be secured on the contact surface 9. Therefore, there is a problem that the seating stability of the chip 1 is poor.

5 to 8, this throwaway tip 30 is different from the conventional throwaway tip 1 in that it has a second arcuate shape formed at the corners of the upper and lower surfaces 2 and 3 that sandwich an obtuse angle. It is in the configuration of the cutting blade 31. That is, in the throw-away tip 30, the second cutting edge 31 has the tangent line L at the end portion P on the short side of the upper and lower surfaces 2, 3 and the ridge line 32 on the short side satisfy 180 °. It is formed so that there is no angle. As a result, the ridgeline 32 on the short side is formed to have a dimension G 2 longer than that of the conventional one, and at the end P of the second cutting edge 31, the second cutting edge 31 and A corner portion that discontinuously intersects the ridge line 32 is formed. A contact surface 40 is formed between the ridgelines 32 of the upper and lower surfaces 2, 3. On the other hand, the other end of the second cutting edge 31 is smoothly formed so that the tangent line at the end matches the ridge line 6 on the long side. In addition, at the corners sandwiching the acute angles of the upper and lower surfaces 2 and 3, the angle formed by the ridgeline 32 on the short side and the ridgeline 6 on the long side is in the range of 70 ° to 85 °.

The chip 30 having the above structure

1 and 13 are detachably mounted and used via mounting bolts. Here, in the tip 30, the seating surface 7 and the contact surface 40 of the tip 30 are respectively set to the first tip mounting seat 11 with the first cutting edge 4 on the acute angle side thereof protruding from the end surface 12. It is fixed by abutting on the bottom surface 15 and the side surface 16 of the chip mounting seat 11.

According to the chip 30 having the above structure,
Attach the second cutting edge 31 to the end portion P on the short side of the upper and lower surfaces 2, 3.
Since the tangent line L and the ridgeline 32 on the short side are formed so as to form an angle of less than 180 °, the length G 2 of the ridgeline 32 on the short side is set to be shorter than that of the conventional short side as shown in FIG. It is possible to secure a length longer than the length G 1 of the side ridge. For this reason, when mounted on the cutter body 10, it is possible to obtain much better seating stability than the conventional tip 1. As a result, as shown in FIG. 8, a straight line portion A longer than the conventional one is formed at the intersection with the ridgeline 6 on the long side, so that the effective blade length of the cutting edge 6 on the long side is increased. Can be set.

In addition, since the angle of the acute corners of the tip 30 that sandwich the first cutting edge 4 is formed in the range of 70 ° to 85 °, when the tip 30 is mounted in the wrong orientation, In addition, the side surface of the tip 30 does not come into contact with the side surface of the tip mounting seat, the second cutting edge 31 protruding from the short surface does not have a sufficient lateral clearance angle, or the tip 30 is on the end face 12 side. Since the mounting bolt and the screw hole cannot be screwed together due to misalignment, the operator can easily recognize the mounting error. The angle is 7
If the angle is less than 0 °, a sufficient lateral clearance angle can be obtained for the first cutting edge 4, but it becomes difficult to machine the side surface of the tip mounting seat, and especially when the width of the tip 30 is large This is inconvenient because the back metal in the width direction of the main body 1 becomes small. On the other hand, if the angle exceeds 85 °, a sufficient lateral clearance angle cannot be maintained in the first cutting edge 4 and, when the tip 30 is mounted in the wrong direction, the mounting error can be easily determined. It is inconvenient because it can not be done. Therefore, it is preferable that the angle of the acute corner portion is formed in the range of 70 ° to 85 °.

As described above, the throw-away tip of the present invention has the arc-shaped second cutting edges formed at the corners sandwiching the obtuse angle on the upper and lower surfaces of the parallelogram.
Since the tangent line at the end of the short side of the upper and lower surfaces and the ridge line of the short side are formed to form an angle of less than 180 °, the area of the contact surface should be secured larger than that of the conventional one. Therefore, the seating stability is excellent, and the effective blade length of the cutting edge on the long side can be set large.
