Abstract
The utility model discloses a combination cutting drill utensil, including drilling rod and the drill lip of setting at the drilling rod front end, be equipped with screw guide scrap groove on the surface of drilling rod, the drill lip includes inside edge, well sword and outside, inside edge, well sword and outside become step like setting in proper order, all are equipped with the cutting knife edge in the inboard outside of inside edge, well sword and outside, are equipped with the protruding muscle of horizontal enhancement on inside edge's side, are equipped with heat dissipation channel at the center of drilling rod, are equipped with the heat conduction post pole that is linked together with heat dissipation channel on the side of well sword. The utility model has the advantages of simple structure, its drill lip comprises outside, well sword and inside edge, so when drilling, about 13 work load is all only born to every cutting edge at cutting process to can reduce the drilling noise, and adopt three drill lip to share some cutting, thus use difficult tipping when driling, thus the stability and the reliability of drilling guaranteed, long service life, well just the practicality is strong for the suitability.
Description
Technical field
The utility model belongs to rig technical field and in particular to a kind of combination cutting drill has.
Background technology
It is typically necessary boring in workpiece process, the drilling tool of conventional art mainly by drilling rod and is arranged on drilling rod
The drill lip composition of end, due to its general only one of which drill lip, so easily produce the situation of tipping in boring, thus can shadow
Ring stability in use and the service life of drilling tool, applicability and practicality are restricted.
Content of the invention
In order to solve above-mentioned technical problem, the purpose of this utility model is that a kind of structure of offer is simple, can effectively prevent from boring
The combination cutting drill tool of tool tipping and strong applicability.
The technical scheme realizing the utility model purpose is a kind of combination cutting drill tool, includes drilling rod and is arranged on described drilling rod
The drill lip of front end, is provided with screw thread dregs guiding groove on the surface of described drilling rod, and described drill lip includes inner edge, middle sword and outside, described interior
The stepped setting successively of sword, middle sword and outside, the width of described middle sword is more than the width of inner edge, and the width of outside is more than middle sword
Width, be equipped with cutting knife edge in the medial lateral of described inner edge, middle sword and outside, the side of described inner edge be provided with horizontal stroke
To strengthening convex tendon, it is provided with heat dissipation channel at the center of described drilling rod, the side of described middle sword is provided with and described heat dissipation channel
The heat conduction mast being connected.
Vertical strengthening ribs are additionally provided with the side of described middle sword, the front end of described vertical strengthening ribs is connected to horizontal reinforcement
The middle part of convex tendon and described heat conduction mast is arranged on the side of described vertical strengthening ribs.
The width of described inner edge is 8.8mm, and the width of described middle sword is 10mm, and the width of described outside is 13mm.
The utility model has positive effect：Structure of the present utility model is simple, and its drill lip is by outside, middle sword and interior
Sword forms, so in boring, each blade only bears 1/3 about workload in working angles, and in each blade
Inner side be also equipped with cutting edge, such that it is able to make chip removal more smooth, such that it is able to reduce boring noise, and adopt three
Drill lip has shared part cutwork, thus being not easy tipping using during boring, thus ensure that stability and the reliability of boring
Property, long service life, applicability is good and practical.
Brief description
In order that content of the present utility model is more likely to be clearly understood, below according to specific embodiment and with reference to attached
Figure, is described in further detail to the utility model, wherein：
Fig. 1 is structural representation of the present utility model.
Specific embodiment
(embodiment 1)
Fig. 1 shows a kind of specific embodiment of the present utility model, and wherein Fig. 1 is structural representation of the present utility model
Figure.
See Fig. 1, a kind of combination cutting drill tool, including drilling rod 1 and the drill lip 2 being arranged on described drilling rod 1 front end, in described drilling rod
1 surface is provided with screw thread dregs guiding groove 3, and described drill lip 2 includes inner edge 21, middle sword 22 and outside 23, described inner edge 21, middle sword 22 and
Outside 23 stepped setting successively, the width of described middle sword 22 is more than the width of inner edge 21, and the width of outside 23 is more than middle sword
22 width, is equipped with cutting knife edge in the medial lateral of described inner edge, middle sword and outside, sets on the side of described inner edge 21
There is horizontal reinforcement convex tendon 24, be provided with heat dissipation channel 4 at the center of described drilling rod 1, the side of described middle sword 22 is provided with and institute
State the heat conduction mast 5 that heat dissipation channel 4 is connected.
Vertical strengthening ribs 25 are additionally provided with the side of described middle sword 22, the front end of described vertical strengthening ribs 25 is connected to horizontal stroke
It is arranged on the side of described vertical strengthening ribs 25 to the middle part and described heat conduction mast 5 strengthening convex tendon 24.
The width of described inner edge is 8.8mm, and the width of described middle sword is 10mm, and the width of described outside is 13mm.
Structure of the present utility model is simple, and its drill lip is made up of outside, middle sword and inner edge, so in boring, each
Blade all only bears 1/3 about workload in working angles, and is also equipped with cutting edge in the inner side of each blade, thus
Chip removal can be made more smooth, such that it is able to reduce boring noise, and shared part cutwork using three drill lips,
Thus using boring when be not easy tipping, thus ensure that stability and the reliability of boring, long service life, applicability good and
Practical.
Obviously, above-described embodiment of the present utility model is only intended to clearly illustrate the utility model example, and
It is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, in described above
On the basis of can also make other changes in different forms.There is no need to give to all of embodiment
Exhaustive.And these belong to the obvious change that connotation of the present utility model extended out or change and still fall within this practicality
New protection domain.
