Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides an embodiment: a pressureless sintering tool bit comprises a cutter head 1 and a cutter body 2, wherein the cutter body 2 is uniformly arranged on the front surface of the cutter head 1, a first cutting end 3 is arranged on one side of the cutter body 2, a second cutting end 4 is arranged on the cutter body 2 far away from the first cutting end 3, first heat dissipation ports 7 are arranged on the upper surfaces of the first cutting end 3 and the second cutting end 4, the first heat dissipation ports 7 are hemispherical, the contact surface between the first heat dissipation ports 7 and air is increased, second heat dissipation ports 8 are arranged on the lower surfaces of the first cutting end 3 and the second cutting end 4, the second heat dissipation ports 8 are conical, the contact surface between the second heat dissipation ports and air is increased, heat exchange is facilitated, a first cutting surface 9 is arranged on the outer side of the first cutting end 3, first diamond particles 10 are embedded in the first cutting surface 9, a second cutting surface 11 is arranged on the outer side of the second cutting end 4, the inclination angle of the first cutting surface 9 is larger than that of the second cutting surface 11, convenient difference, and because the tangent plane of general gradient can cut the material of different materials, promote the practicality, the inboard of second tangent plane 11 is inlayed and is had second diamond granule 12.

The inner side of the cutter body 2 is penetrated with a connecting inner rod 5, connecting members 6 are embedded between the cutter body 2 and the first cutting end 3 and between the cutter body 2 and the second cutting end 4, the connecting inner rod 5 and the connecting members 6 are made of tungsten, and the inner part of the cutter head can be added during sintering without being influenced by the sintering process.

The connecting member 6 comprises a first wafer 601, a second wafer 602 and a connecting rod 603, the first wafer 601 is located inside the cutter body 2, the second wafer 602 is arranged outside the first wafer 601, the second wafer 602 is embedded inside the first cutting end 3 and inside the second cutting end 4, the connecting rod 603 is installed between the first wafer 601 and the second wafer 602, the first wafer 601, the second wafer 602 and the connecting rod 603 form an I shape, the structure is stable, the connectivity is enhanced, the connection between the first cutting end 3 and the second cutting end 4 and the cutter body 2 is more stable, and the stability of the cutter head is improved.

The working principle is as follows: during the use, blade disc 1 rotates at high speed in the drive of motor, when motor corotation, first tangent plane 9 and material contact, first diamond granule 10 that first tangent plane 9 inside was inlayed rubs with the material, first diamond granule 10 hardness is big, constantly with material wearing and tearing, thereby play the effect of cutting, when the motor reversal, second tangent plane 11 and material contact, second diamond granule 12 that second tangent plane 11 inside was inlayed rubs with the material, thereby play the effect of cutting, both ends all can play the cutting action, strengthen the practicality of tool bit.

When the cutting, first cutting end 3 or second cutting end 4 wear and tear with the material, produce a large amount of heats, because first thermovent 7 has increaseed the contact surface with the air with second thermovent 8 to promote the heat transfer between first thermovent 7 and second thermovent 8 and the air, strengthened the heat dissipation of first cutting end 3 and second cutting end 4, strengthened the convenience that the tool bit used.

Because the pole 5 and the connecting elements 6 in connecting are installed to inside and first cutting end 3 of blade 2 and second cutting end 4 between, the material of pole 5 and connecting elements 6 in the connection is tungsten, can add the mould when the sintering, strengthens the connectivity between blade 2 and the first cutting end 3 in both ends or the second cutting end 4 for it is more stable to be connected between first cutting end 3 and second cutting end 4 and the blade 2, promotes the stability of tool bit.
