Embodiment
In order to facilitate the understanding of the purposes, features and advantages of the present invention, below in conjunction with the accompanying drawings to the present invention
Embodiment be described in detail.
It refer to Fig. 1, the present invention provides a kind of deburrer, from right to left respectively handle of a knife 3, connector 2 and knife
First 1, Fig. 3 is refer to, the overall cutter head 1 is in cylinder, by forming helical form around centrosymmetric three blades 11, each
The cutting edge of blade 11 is 45 ° for the angle between 45 °, namely two sides of blade 11, and the cutting face of each blade 11 is located at
The side of cylinder, when cutter head 1 rotates, three blades 11 rotate simultaneously, and centrifugal force is changed to form cutting force.
It is preferred that cutter head 11 is designed with anterior angle, and cutting edge processing is done, it is ensured that cutting edge strength, cutter head 1 is closed using hard
Gold.
Fig. 1 to Fig. 3 is continued referring to, chip area 12, two chip areas is provided between each two blade 11 on cutter head 1
12 cell wall is the side of two adjacent blades 11, and chip area 12 extends from cutter head 1 to connector 2, extends to connector 2
First paragraph 22, the bearing of trend of chip area 12 and the axis direction antarafacial of connector 2, as shown in Fig. 2 when the cutter level is put
When putting, the bearing of trend positioned at the chip area 12 of side is downward, in addition from cutter head 1 to the direction of first paragraph 22, chip area 12
Width is gradually reduced.
Please emphasis reference picture 2,2 points of connector is first paragraph 22 and second segment 23, and first paragraph 22 is connected with cutter head 1, second
Section 23 is connected with handle of a knife 3, and the diameter of first paragraph 22 is less than the diameter of cutter head 1, and the diameter of second segment 23 is more than the straight of first paragraph 22
Footpath, this is to strengthen the intensity of connector 2, it is to avoid meticulous connector 2 easily fractures in use.
The junction of first paragraph 22 and cutter head 1 sets chamfering 21, and first paragraph 22 and the junction diameter of second segment 23 become
Change, be also provided with chamfering 21.
Fig. 4 is refer to, the cutter provided using the present invention can make cutter head 1 out of drilling to drilling when removing flanging burr
Orifice part stretches out, rotary cutter 1 so that three blades 11 rotate, and is eccentric processing during rotation, and three blades 11 contact drilling hole
Inner circumferential, three blades 11 cut flanging burr in rotary course, and flanging burr is fallen to after being cut in chip area 12, please
Reference picture 1, the width of chip area 12 is gradually reduced, and chip area 12 bearing of trend gradually downward, then the flange after being cut
Burr is gradually gathered along chip area 12 to be dropped, and after the flanging burr of drilling is all cut, cutter head 1 is moved back along backtracking
Knife.
The present invention provides a kind of deburrer, and it has handle of a knife 3 and the cutter head 1 being fixed on the handle of a knife 3, the present invention
The cutter head 1 of offer around centrosymmetric three blades 11 by forming helical form, so in the drilling being molded, by cutter head
1 is stretched into the drilling, rotates three blades 11, and the burr around drilling is scraped off, chip removal is provided between each two blade 11
Groove 12, after three blades 11, which rotate, scrapes off the burr around drilling, falls into chip area 12, in three rotation processes of blade 11
In, with Action of Gravity Field, dropped along chip area 12.Therefore the deburrer that the present invention is provided has advantages below：
1. this deburrer can effectively remove the flanging burr in drilling exit, and the Tool Design is succinct, system
Cause low, be conducive to cost control, the probability that flanging burr occurs in original drill bit processing is about 50%, is thoroughly disappeared after improvement
Except the problem, can be removed with 100%, the cutter life of drill bit is promoted to 400 by original 200, separate room cost by
1.8RMB is down to 0.9RMB.Due to about 50,000 yuan of the disposable input of handle of a knife 3, the separate room cost about 0.2RMB of deburrer.Therefore
0.7 yuan/part of the actual annual saving cost of charp tool × 400,000/year=280,000/year；
2. this deburrer is from drill center feed, deburring Hou Cong centers withdrawing is completed, is not damaged so machined
The surface of part, it is ensured that part crudy and technological requirement.
Obviously, those skilled in the art can carry out the spirit of various changes and modification without departing from the present invention to invention
And scope.If these modifications and variations of the present invention belong within the scope of the claims in the present invention and its equivalent technologies, then
The present invention is also intended to including these changes and modification.
