Description
Technical field
This utility model belongs to technical field of tools, particularly relates to a kind of fluted drill, especially a kind of rake face
Reconditioning fluted drill.
Background technology
The common fluted drill of tradition, is born for over 100 years more than a hundred years from it, and planform change is little, along with constantly sending out of science and technology
Exhibition, new material continues to bring out, the requirement that proposition continuous to drill bit is new, and the common fluted drill of tradition is primarily present following problem: 1.
On main sword, the anterior angle change in value of each point is very big, has been negative rake at drill core, and machining condition is poor.2. chisel edge is oversize, has very
Big sword drift angle, and be again the biggest negative rake, machining condition is worse, thus axially drag is big, feels relieved bad.The most main sword is long,
Cutting width, chip curling becomes to get spiral shell volume, and shared spatial volume is big, causes chip removal not smooth, and cutting fluid difficultly flows into.
In order to improve the performance of tradition fluted drill, people have employed numerous method, substantially increases the performance of fluted drill, so
And the anterior angle change in value of each point is the biggest on main sword, still also having the existence of negative rake at drill core, machining condition difference does not has yet
Have and obtain basic change.
Therefore, the problems referred to above are asking of should paying attention to and solve during to fluted drill structure design and use
Topic.
Utility model content
For the problem of above-mentioned existence, this utility model provides one to overcome defect of the prior art, it is provided that Yi Zhongjie
Structure is reasonable, and intensity is high, the rake face reconditioning fluted drill that cutting effect is good.
Technical solution of the present utility model is: a kind of rake face reconditioning fluted drill, including shank and blade, described
Blade offers helicla flute, and the top of described blade is apex point, and described apex point includes chisel edge, rake face, main cutting edge and Hou Gou
Rib, described rake face, main cutting edge and rear ditch rib through while reconditioning processing form a reconditioning face at described spiral fluted top,
Described reconditioning face is tapered, and including dual-side and base, described base is curve, described side lay respectively at main cutting edge and after
On the sideline of ditch rib, described rear ditch seamed edge its length range of line upper side edge is the 1/3-1 of described rear ditch rib.
Further improvement of the utility model is: the angle between its main cutting edge of described apex point is 135 °.
Further improvement of the utility model is: the angle between described chisel edge and described main cutting edge is 118 °.
Further improvement of the utility model is: the surface configuration of described main cutting edge has carbon nitride coatings.
This utility model provides a kind of rake face reconditioning fluted drill, while the rake face of fluted drill is carried out reconditioning, also
Main cutting edge is carried out reconditioning, shortens the length of chisel edge, make the anterior angle numerical value of each point on main cutting edge reduce and change eases up,
Improve anterior angle numerical value, be improved particularly the numerical value of anterior angle at drill core so that the front angle number at drill core be on the occasion of, improvement is cut
Cut condition.
The beneficial effects of the utility model are: its simple in construction, reasonable in design, shorten the length of chisel edge, the row of improving
The puzzlement of bits chip breaking, reduces drilling drag, reduces axial force than common fluted drill, it is simple to cutting fluid flows into cutting region, reduces
The temperature of cutting edge, alleviates the abrasion of cutting edge, improves the durability of drill bit, make operation safer, thus improve
Production efficiency.

Detailed description of the invention
In order to deepen understanding of the present utility model, below in conjunction with drawings and Examples, this utility model is done further
Describing in detail, this embodiment is only used for explaining this utility model, does not constitute protection domain of the present utility model and limits.
As shown in the figure: technical solution of the present utility model is: a kind of rake face reconditioning fluted drill, including shank 1 He
Blade 2, described blade 2 offers helicla flute 3, and the top of described blade 2 is apex point, and described apex point includes chisel edge 4, rake face 5,
Main cutting edge 6 and rear ditch rib 7, described rake face 5, main cutting edge 6 and rear ditch rib 7 through while reconditioning process at described helicla flute
Top form a reconditioning face 8, described reconditioning face 8 is tapered, and including dual-side and base, described base is curve, described side
While lay respectively on the sideline of main cutting edge 6 and rear ditch rib 7, described rear ditch seamed edge its length range of line upper side edge is described rear ditch
The 1/2 of rib 7, the angle between its main cutting edge 6 of described apex point is 135 °, the angle between described chisel edge and described main cutting edge
Being 118 °, the surface configuration of described main cutting edge has carbon nitride coatings.
This utility model provides a kind of rake face reconditioning fluted drill, while the rake face 5 of fluted drill is carried out reconditioning, also
Main cutting edge 6 is carried out reconditioning, shortens the length of chisel edge 4, make the anterior angle numerical value of each point on main cutting edge 6 reduce and change becomes
Slow, improve anterior angle numerical value, be improved particularly the numerical value of anterior angle at drill core so that the front angle number at drill core be on the occasion of, change
Kind machining condition.
The present embodiment provides the benefit that: its simple in construction, reasonable in design, shortens the length of chisel edge, improves chip removal
The puzzlement of chip breaking, reduces drilling drag, reduces axial force than common fluted drill, it is simple to cutting fluid flows into cutting region, reduces
The temperature of cutting edge, alleviates the abrasion of cutting edge, improves the durability of drill bit, makes operation safer, thus improves life
Produce efficiency.
Skilled person will appreciate that of the industry, this utility model is not restricted to the described embodiments, above-described embodiment and
