Fig. 1 is a partial front view of embodiment 1 of the present invention;
fig. 2 is a plan view of embodiment 1 of the present invention;
fig. 3 is a partial front view of embodiment 2 of the present invention;
fig. 4 is a plan view of embodiment 2 of the present invention.
Detailed Description
Example 1:
referring to fig. 1-2, a novel drill comprises a head 1 and a drill body 2, wherein the head 1 is connected and fixed to the top end of the drill body 2, and a spiral chip guide groove 21 is formed in the drill body 2, and the spiral chip guide groove 21 is in the prior art, so that the details are not repeated herein.
The head part 1 is provided with a main alloy blade 3 and an even number of auxiliary alloy blades 4, and the auxiliary alloy blades 4 are respectively arranged at two sides of the main alloy blade 3. The number of the secondary alloy blades 4 is preferably two, and the present embodiment is exemplified by three. The two auxiliary alloy blades 4 are arranged in parallel and are crossed with the main alloy blade 3 in space, and the specific structure is that the two auxiliary alloy blades 4 are not in direct contact connection with the main alloy blade 3. The imaginary included angle formed by the auxiliary alloy blade 4 and the main alloy blade 3 is A, A is more than or equal to 5 degrees and less than or equal to 30 degrees, and A is preferably 12 degrees. The imaginary included angle is formed by intersecting an imaginary center line of the sub-alloy blade 4 and an imaginary center line of the main alloy blade 3.
The head part 1 is provided with two chip removal ports 5, and the chip removal ports 5 are communicated with the spiral chip guide grooves to form a chip removal effect. The chip removal port 5 is specifically positioned between the main alloy blade 3 and the secondary alloy blade 4, so that the chip removal port 5 and the secondary alloy blade 4 form a right-angle arrangement, and the chip removal effect is further better.
Further, the main alloy blade 3 and the two auxiliary alloy blades 4 are welded and fixed on the head 1. The welding arrangement is adopted, so that the connection strength is ensured, and the head part 1 is prevented from being broken in the cutting process. The height of the secondary alloy blade 4 is one third to two thirds of the height of the primary alloy blade 3. The height of the secondary alloy blade 4 is preferably half of that of the primary alloy blade 3. The height limitation also ensures the cutting effect.
Adopt main alloy blade 3 and vice alloy blade 4 to form three blade, form multiunit cutting effect, improve holistic work efficiency, for current drill bit, adopt this kind of structure setting, improved holistic efficiency greatly.
Example 2:
referring to fig. 3-4, a novel drill comprises a head 1 and a drill body 2, wherein the head 1 is connected and fixed to the top end of the drill body 2, and a spiral chip guide groove 21 is formed in the drill body 2, and the spiral chip guide groove 21 is in the prior art, so that the details are not repeated herein.
The head part 1 is provided with a main alloy blade 3 and an even number of auxiliary alloy blades 4, and the auxiliary alloy blades 4 are respectively arranged at two sides of the main alloy blade 3. The number of the secondary alloy blades 4 is preferably two, and the present embodiment is exemplified by three. The two secondary alloy blades 4 and the main alloy blade 3 are arranged in parallel, namely, the three alloy blades are all parallel.
