Abstract
The utility model discloses a kind of novel timber deep hole processing chit drills, cutting head includes two symmetrically arranged fan-shaped cutting blocks, the 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.Utility model has the advantages that the utility model novel timber deep hole processing chit drill, 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 utility model 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.
Utility model content
That the technical problem to be solved by the present invention is to provide a kind of cuttings is sharp, enough improves and trepanning velocity and can be improved
The novel timber deep hole processing chit drill of service life.
In order to solve the above technical problems, the technical solution of the utility model are as follows: 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, and two sectors are cut
The cutting edge that a side of block structure in line is equipped with raised side height is cut, and the center of cutting edge is set in horn structure
It sets；The outer end of another side of described two fan-shaped cutting blocks, which is equipped with, thickeies cutting edge, and each fan-shaped cutting blocks are equipped with and thicken cutting
The chip space extended from side to arc-shaped side is equipped among the side of sword.
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.
Utility model has the advantages that
(1) the utility model novel timber deep hole processing chit drill, changing Double-blade structure is fan-shaped cutting blocks and cutting edge
Composite structure, the punching of multiple cutting head can speed faster, cut sharper, and fan-shaped cutting block structure increases drilling circularity,
Meanwhile it can guarantee uniform force in cutting process, and then guarantee cutting precision；It is cut in addition, being equipped with to thicken in each fan-shaped cutting blocks
The chip space for being equipped among the side of sword and extending from side to arc-shaped side is cut, 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；
(2) the utility model novel timber deep hole processing chit drill is equipped with annular stop in the outer lower end of two sectorial blocks
It is smooth that deep cuts face can be effectively controlled in block；
(3) the utility model novel timber deep hole processing chit drill, the depth of chip space are the 3/5 of fan-shaped cutting blocks thickness
~4/5, to be more advantageous to chip removal.
Detailed description of the invention
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
Fig. 1 is the structural schematic diagram of the utility model novel timber deep hole processing chit drill.
Specific embodiment
The following examples can make professional and technical personnel that the utility model be more fully understood, but therefore will not
The utility model is 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.
The advantages of basic principles and main features and the utility model of the utility model have been shown and described above.This
The technical staff of industry is retouched in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments
That states only illustrates the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model
It will also have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention.This is practical new
Type is claimed range and is defined by the appending claims and its equivalent thereof.
