Description
Technical field
The utility model is related to a kind of processing high temperature alloy solid carbide drills, belong to metal cutting process cutter skill
Art field.
Background technology
Since high temperature alloy is a series of excellent with high intensity, high tenacity, high thermal stability, heat-resistant anti-fatigue and lower thermal conductivity etc.
Point so that this kind of alloy machining is more difficult, in addition, processing high temperature alloy is easily formed built-up edge, generates processing hardening
And rebound phenomenon so that cutting environment is complicated and changeable, these factors can all cause cutting resistance to increase, cutting temperature raising, knife
Tool abrasion aggravates namely proposes more stringent requirement to the structure type and geometric parameter of cutter.
For difficult-to-machine materials such as high temperature alloys, the inner edge and outside of bit cutting part, which use, to be directly intersected transition or adopts
The increase of drilling resistance and drilling temperature is not only caused to increase, but also before inner edge and outside intersection can be accelerated with form of straight lines transition
The breakage of knife face and rear knife face, when using bit cutting of the rear knife face for back-off form after contact friction of the knife face with workpiece compared with
Greatly, the angle of knife face and rake face is excessive after cutting tip or too small machining and the cutter life of being all unfavorable for improves, in addition
Using more sharp cutting edge cutting high rigidity high temperature alloy when cutting edge be easy to generate micro- collapse and peeling phenomenon, therefore process high
During temperature alloy, to improve tool life and machining accuracy and efficiency, for the processing characteristics of this kind of alloy, it is desirable that drill bit is not only
Structure design is reasonable, and the geometric parameter of key position is proper.
Utility model content
The purpose of the utility model is to provide one kind is simple in structure, service life is long, geometric parameter reasonably processes height
Temperature alloy solid carbide drill, to overcome deficiency of the prior art.
The technical solution of the utility model：It is a kind of processing high temperature alloy solid carbide drill, including handle of a knife and with
The helical edges that handle of a knife is connected as one have chisel edge in the end set of helical edges and are symmetricly set on the cutting at chisel edge both ends
Sword, is provided with the negative chamfered edge that width is 0.05~0.1mm, angle is 15~20 ° on the cutting edge, the inner edge of cutting edge and outer
Sword is circular arc type transition.
Further, the azimuth of the chisel edge is 55~60 °.
Further, the negative chamfered edge width is 0.05~0.1mm, angle is 15~20 °
Further, the top angle of the cutting edge is 125~130 °, and relief angle is 8~12 ° of straight line relief angle, cutting edge
Interior angle of cutting edge is 4~6 °.
Further, the helical angle of the helical edges is 30~35 °, and radial rake is 0~4 °.
Due to the adoption of the above technical scheme, the utility model has the advantage of：The inner edge of the cutting edge of the utility model and
Outside is using circular arc type transition, therefore drilling resistance can be reduced in practical drilling process, while the negative chamfered edge on cutting edge
Cutting edge strength is increased, has delayed the breakage and peeling of cutting edge to a certain extent, rear knife face reduces for the relief angle of form of straight lines
Contact friction between workpiece, along with the rational parameter designing of each main portions, these favorable factors ensure reality jointly
The durability of drill bit in the working angles of border, particularly performance is more excellent on the difficult-to-machine materials such as drilling high temperature alloy,
Can finally meet the needs of efficient drilling high temperature alloy.

Specific embodiment
In order to make the utility model aim, technical solution and advantage clearer, below in conjunction with the accompanying drawings and embodiment pair
The utility model is described in further detail.
The embodiment of the utility model：The structural representation of the processing high temperature alloy solid carbide drill of the utility model
As shown in figs. 1 to 6, including handle of a knife 4 and the helical edges being connected as one with handle of a knife 43, the azimuth 5 of the chisel edge 1 is figure
58°；There is chisel edge 1 in the end set of helical edges 3 and be symmetricly set on the cutting edge 2 at 1 both ends of chisel edge, set on cutting edge 2
The negative chamfered edge 11 that width is 0.08mm, angle is 18 ° is equipped with, the inner edge and outside of cutting edge 2 are circular arc type transition.It is described to cut
The top angle 6 for cutting sword 2 is 125 °, and relief angle is 8 ° of straight line relief angle 9, and the interior angle of cutting edge 10 of cutting edge 2 is 5 °.The helical edges 3
Helical angle 7 for 32 °, radial rake 8 is 3 °.
During using drill bit drilling high temperature alloy with above structure and parameter attribute, averagely can drilling GH4169 high temperature close
Golden 320~350 holes/only, not only drilling hole amount is more, but also pore size precision is high, it is ensured that highly-efficient processing.
