Description
Technical Field
The utility model relates to a circle ripple saw bit belongs to the technical field of saw bit.
Background
At present, the sintered saw blade mainly comprises a corrugated sheet, and the corrugated sheet mainly comprises oblique corrugations, so that the sintered saw blade becomes a mainstream product in the market. Other wave structures are generally determined according to specific characteristics of the cutting object, and generally have no general applicability.
For the oblique corrugated saw blade, the corrugated protrusions are approximately in a straight line state parallel to the radius, one surface of each protrusion is fixedly connected with the cutter head, the other surface of each protrusion is a friction surface which is in contact with a cutting object and plays a role in cutting and grinding, and the whole oblique corrugated saw blade is approximately a cuboid. Because the size of the saw blade in the circumferential direction is limited, the saw blade cannot be too thick, and meanwhile, the saw blade cutting and grinding work stress is in the circumferential direction and is basically vertical to the corrugation, so that the strength of the corrugated structure is reduced. On one hand, the consolidation area of the oblique corrugations and the cutter head is smaller than that of the curve corrugations; also, the oblique wave is stressed in the same direction throughout the length of the wave, all of which causes the oblique wave to have a lower strength.
Because the included angle between each oblique ripple and the radial direction of each oblique ripple is the same, the force direction of each ripple borne by any point of a cutting object is the same, the cutting efficiency is reduced, and the quality of the cut section is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a circular ripple saw bit has improvement ripple self intensity, improves section quality after the cutting to further improve the effect of sharpness.
In order to realize the purpose, the utility model discloses a technical scheme is:
the utility model provides a circular ripple saw bit, includes circular saw bit base member and the diamond segments of sintering at saw bit base member outward flange, set up the ripple of S-shaped in its circumferencial direction staggered arrangement excircle groove and interior circular slot in the inside and outside both sides of diamond segments, in between the excircle groove, the first half of ripple is concentric with the excircle groove, and the latter half of ripple is concentric with interior circular slot.
The utility model discloses technical scheme's further improvement lies in: the width of the corrugation is larger than the thickness of the diamond tool bit.
The utility model discloses technical scheme's further improvement lies in: the radius of curvature of the corrugations is-times the width of the corrugations.
The utility model discloses technical scheme's further improvement lies in: the ripples set up along the radial of saw bit base member, and two ripples that set up relatively are a cycle.
The utility model discloses technical scheme's further improvement lies in: the ripples of diamond segments both sides about stagger half cycle along circumference.
The utility model discloses technical scheme's further improvement lies in: and a reinforcing ring with the thickness equal to that of the diamond tool bit is arranged between the saw blade matrix and the diamond tool bit.
Since the technical scheme is used, the utility model discloses the technological effect who gains has:
the utility model discloses a circular or circular arc ripple has improved ripple self intensity, has improved the whole life-span of saw bit. Particularly, the curvature radius of the corrugation is 3-7 times of the width of the corrugation, thereby ensuring the obvious effect of improving the strength. When the curvature radius of the corrugations is larger than 7 times of the width of the corrugations, the improvement effect on the strength of the corrugations is weakened; when the radius of curvature of the corrugations is less than 3 times the width of the corrugations, the sharpness of the saw blade is significantly reduced.
The utility model discloses a crooked direction of ripple has the effect that has improved the section quality after sharpness and the cutting along radius symmetry.
The utility model discloses set up the beaded finish between saw bit base member and diamond segments, through the effect of beaded finish, improved the bonding strength of tool bit with the base member.

Detailed Description
The present invention will be described in further detail with reference to the following drawings and specific embodiments:
the utility model discloses a circular ripple saw bit, the main objective has improvement ripple self intensity for providing one kind, improves the section quality after the cutting to further improve the oblique ripple saw bit of sharpness effect. As shown in fig. 1-2, the saw blade comprises a circular saw blade base body 1 and a diamond cutting head 2 sintered on the outer edge of the saw blade base body 1, wherein a whole circle of reinforcing ring 6 with the thickness equal to that of the diamond cutting head 2 is arranged between the diamond cutting head 2 and the saw blade base body 1, and the bonding strength between the diamond cutting head and the saw blade base body 1 is improved through the reinforcing ring 6.
The diamond tool bit is characterized in that two layers of integral outer circular grooves 3 and inner circular grooves 4 which are staggered in the circumferential direction are arranged in the radial direction of the diamond tool bit 2, the outer circular grooves 3 and the inner circular grooves 4 are respectively arranged in gaps between the two circular grooves, two sides of each outer circular groove 3 and each inner circular groove 4 in the circumferential direction are two sections of concentric circular arcs, the circular arcs surround the outer circular grooves 3 and the inner circular grooves 4, the circular arcs surrounding the outer circular grooves 3 and the circular arcs surrounding the inner circular grooves 4 are smoothly connected in opposite bending directions, S-shaped corrugations 5 are formed, the width of each corrugation 5 is larger than the thickness of the diamond tool bit 2, and two opposite S-shaped corrugations 5 are in one period; the excircle groove 3, the inner circle groove 4 and the ripple 5 which are arranged on the upper surface and the lower surface of the diamond tool bit 2 have a half period of difference along the circumferential direction.
The curvature radius of the upper and lower circular arcs of the corrugations 5 is 3-7 times of the width of the corrugations 5, so that the obvious effect of improving the strength is ensured. When the curvature radius of the corrugations 5 is larger than 7 times the width of the corrugations 5, the effect of improving the strength of the corrugations 5 is weakened; when the radius of curvature of the corrugations 5 is less than 3 times the width of the corrugations 5, the sharpness of the saw blade is significantly reduced.
