Description
Technical field
The utility model relates to drill bits, are specifically related to super solid center bit.
Background technique
When carrying out deep hole machining to wood materials, most-often used tool is solid center bit, but common solid center bit is cut
Resistance is larger when cutting, cause bore processing efficiency it is lower, chip removal performance is poor, although by solid center bit increase cutting edge come
Stationarity is poor when reducing resistance, but working, and heat dissipation is slow, is not durable.
Summary of the invention
In order to solve the above-mentioned technical problem, the utility model provides super solid center bit, stationarity when the drill bit works
Good, good heat dissipation, reliability and durability, the technical solution of the utility model is as follows:
Super solid center bit, including drilling rod, cutting portion, the cutting portion are fixed on one end of the drilling rod, the cutting
Portion includes the first, second cutting portion, and the first cutting portion is embedded in the top of second cutting portion, second cutting portion and institute
The one end for stating drilling rod is fixedly connected, and the axis of first, second cutting portion and the drilling rod is on the same line；Described first
Cutting portion includes the first, second cutting edge, and first, second cutting blade structure is identical, first cutting edge by first, the
Two, third inclined-plane is constituted, described first, the one side on third inclined-plane be fixedly connected with the both ends on second inclined-plane, described first,
Second, third inclined-plane is equipped with a wedge angle upward, and first, second inclined-plane is connected at obtuse angle, it is described second, third tiltedly
Face is connected at obtuse angle；The third inclined-plane vertex of the third inclined-plane of first cutting edge and second cutting edge coincides to be formed
The two sides of wedge angle, the wedge angle are equipped with the first groove；Second cutting portion is equipped with 2 the second grooves, second groove
Section it is arc-shaped, the both ends of first cutting portion protrude from the inner wall of second groove.
Further, first groove is angularly disposed.
Further, second groove is angularly disposed.
Further, first cutting portion is hard alloy material.
Beneficial effect
The utility model structure is simple, and cutting portion includes the first, second cutting edge, the first cutting edge by first, second, the
Three inclined-planes are constituted, and the first, second, third inclined-plane is equipped with a wedge angle upward, and intermediate equipped with the first groove, with second
The second groove on cutting portion matches, and can not only preferably arrange sawdust and stationary performance is good, rapid heat dissipation, the first cutting portion
Using hard alloy material, the durability of solid center bit is improved.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of the first cutting portion in the utility model.

Second cutting portion 22 is fixedly connected with one end of the drilling rod 1, the axis of first, second cutting portion 21,22 and the drilling rod 1
Line is on the same line；First cutting portion 21 includes the first, second cutting edge 211,212, first, second cutting edge
211,212 structures are identical, and first cutting edge 211 is made of the one 3, the 2nd 4, third inclined-plane 5, the described 1st, third it is oblique
The one side in face 5 is fixedly connected with the both ends on second inclined-plane 4, the described 1st, the 2nd 4, third inclined-plane 5 be equipped with a court
On wedge angle, the described 1st, the second inclined-plane 4 connected at obtuse angle, the described 2nd 4, third inclined-plane 5 connects at obtuse angle；Described first
5 vertex of third inclined-plane of the third inclined-plane 5 of cutting edge 211 and second cutting edge 212 coincides to form wedge angle, the wedge angle
Two sides be equipped with the first groove；Second cutting portion 22 is equipped with 2 the second grooves 6, and the section of second groove 6 is in arc
Shape, the both ends of first cutting portion 21 protrude from the inner wall of second groove 6, and first groove is angularly disposed, described
Second groove 6 is angularly disposed, and first cutting portion 21 is hard alloy material.
Work efficiency is high for the utility model, can quickly radiate, and chip removal performance is good.
The utility model core is merely used to help understand to one kind provided by the embodiments of the present invention above to think
Think, meanwhile, for the general technology person of this field, according to the thought of the present invention, made in specific embodiment and application range
Change also should include in the protection scope of the claims of the present utility model.
