Abstract
The present invention relates to a kind of novel timber deep hole processing chit drill, cutting head includes two symmetrically arranged fan-shaped cutting blocks, and a side of two fan-shaped cutting blocks structures in line is equipped with the cutting edge of raised side height, and the center of cutting edge is arranged in horn structure；The outer end of another side of two fan-shaped cutting blocks, which is equipped with, thickeies cutting edge, and each fan-shaped cutting blocks are equipped with the chip space for being equipped among the side for thickening cutting edge and extending from side to arc-shaped side.The advantage of the invention is that：Novel timber deep hole processing chit drill of the present invention, change the composite structure that Double-blade structure is fan-shaped cutting blocks and cutting edge, multiple cutting head punching meeting speed is faster, it cuts sharper, and fan-shaped cutting block structure increases drilling circularity, meanwhile it can guarantee uniform force in cutting process, and then guarantee cutting precision；In addition, being equipped with chip space, cutting resistance can be reduced, guarantee that chip removal is smooth, thus the service life of novel timber deep hole processing chit drill can be improved.
Description
Technical field
The present invention relates to a kind of boring bar tool, in particular to a kind of novel timber deep hole processing chit drill.
Background technique
Timber chit drill is mainly used for timber deep hole processing, and current chit drill mostly uses greatly Double-blade structure, and cutting is not sharp, often
The phenomenon that often hardwood occur beats motionless problem, and during the cutting process due to discontinuity, often will appear offset causes to add
The shape that work comes out deforms, and subsequent also to be finished, the precision and production efficiency of processing be not high.In addition, making at present
The chit drill of Double-blade structure, there is also the problems that cutting resistance is big and chip removal is unsmooth, in turn result in novel timber deep hole processing
With the low defect of chit drill service life.In addition, the chit drill of Double-blade structure used at present, there is also cutting resistance is big and chip removal not
Smooth problem in turn results in the low defect of Woodworking flat drill service life.
Therefore, research and develop it is a kind of cut it is sharp, enough improve trepanning velocity and can be improved service life novel timber processing
Deep hole is necessary with chit drill.
Summary of the invention
That the technical problem to be solved in the present invention is to provide a kind of cuttings is sharp, enough improves and trepanning velocity and can be improved use
The novel timber deep hole processing chit drill in service life.
In order to solve the above technical problems, the technical scheme is that：A kind of novel timber deep hole processing chit drill, including
Drillstock and cutting head；Its innovative point is：The cutting head includes two symmetrically arranged fan-shaped cutting blocks, two fan-shaped cutting blocks
The a side of structure in line is equipped with the cutting edge of raised side height, and the center of cutting edge is arranged in horn structure；Institute
The outer end for stating another side of two fan-shaped cutting blocks, which is equipped with, thickeies cutting edge, and each fan-shaped cutting blocks are equipped with the side for thickening cutting edge
The chip space extended from side to arc-shaped side is equipped among side.
Further, ring limit block is equipped in the outer lower end of described two fan-shaped cutting blocks.
Further, the depth of the chip space is the 3/5~4/5 of fan-shaped cutting blocks thickness.
The advantage of the invention is that：
(1) novel timber deep hole processing chit drill of the present invention changes the group that Double-blade structure is fan-shaped cutting blocks and cutting edge
Structure is closed, faster, cutting is sharper for multiple cutting head punching meeting speed, and fan-shaped cutting block structure increases the circularity that drills, meanwhile,
It can guarantee uniform force in cutting process, and then guarantee cutting precision；Cutting edge is thickeied in addition, being equipped in each fan-shaped cutting blocks
It is equipped with the chip space extended from side to arc-shaped side among side, cutting resistance can be reduced, guarantees that chip removal is smooth, thus can be improved
The service life of novel timber deep hole processing chit drill；
(2) novel timber deep hole processing chit drill of the present invention is equipped with ring limit block in the outer lower end of two sectorial blocks, can
Effective controlling depth cutting face is smooth；
(3) novel timber deep hole processing chit drill of the present invention, the depth of chip space are the 3/5~4/ of fan-shaped cutting blocks thickness
5, to be more advantageous to chip removal.
Detailed description of the invention
The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
Fig. 1 is the structural schematic diagram of novel timber deep hole processing chit drill of the present invention.
Specific embodiment
The following examples can make professional and technical personnel that the present invention be more fully understood, but therefore not send out this
It is bright to be limited among the embodiment described range.
Embodiment
The present embodiment novel timber deep hole processing chit drill, as shown in Figure 1, including drillstock 1 and cutting head 2；Cutting head 2 is wrapped
Two symmetrically arranged fan-shaped cutting blocks 21 are included, it is high that a side of two 21 structures of fan-shaped cutting blocks in line is equipped with raised side
The cutting edge 22 of degree, and the center of cutting edge 22 is arranged in horn structure；The outer end of another side of two fan-shaped cutting blocks 21 is set
Have and thicken cutting edge 23, and be equipped with ring limit block 24 in the outer lower end of two fan-shaped cutting blocks 21, depth can be effectively controlled and cut
Bevel is smooth；Each sector cutting blocks 21 are equipped with the chip removal for being equipped among the side for thickening cutting edge 23 and extending from side to arc-shaped side
Slot 25, and the depth of chip space 25 is the 3/5~4/5 of 21 thickness of fan-shaped cutting blocks, to be more advantageous to chip removal.
The present embodiment novel timber deep hole processing chit drill changes the group that Double-blade structure is fan-shaped cutting blocks 21 and cutting edge
Structure is closed, faster, cutting is sharper for multiple cutting head punching meeting speed, and fan-shaped cutting block structure increases the circularity that drills, meanwhile,
It can guarantee uniform force in cutting process, and then guarantee cutting precision；Cutting edge is thickeied in addition, being equipped in each fan-shaped cutting blocks 21
It is equipped with the chip space 25 extended from side to arc-shaped side among 23 side, cutting resistance can be reduced, guarantees that chip removal is smooth, thus
The service life of novel timber deep hole processing chit drill can be improved.
Basic principles and main features and advantages of the present invention of the invention have been shown and described above.The skill of the industry
Art personnel it should be appreciated that the present invention is not limited to the above embodiments, the above embodiments and description only describe
The principle of the present invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these
Changes and improvements all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and
