Abstract
The invention relates to the technical field of processing tools, in particular to a combined ceramic drill bit. The combined ceramic drill bit comprises a drill handle, a drill body and a drill bit body, wherein cutting blades for cutting are arranged at the front end of the drill bit body; rotating trails of the cutting blades are arranged on the drill body; a chip groove is formed between the rotating trails of the two cutting blades; the drill handle is a carbon steel drill handle; the drill body is a carbon steel drill body; the drill bit body is a ceramic drill bit body; a metal fixing rod formed in the center of the lower end of the drill body covers the center of the drill bit body and fixedly connects the drill body with the drill bit body; the fixing rod penetrates through the drill bit body; a drill point of the drill bit body is formed at the lower end of the fixing rod. According to the combined ceramic drill bit, the produced heat can be timely transferred to the drill body and the drill handle through the metal fixing rod, so that the problem of the poor heat dispersing effect of a ceramic drill bit can be effectively solved; the combined ceramic drill bit is simple in structure, good in cooling effect, outstanding in abrasion resistance, long in service life, and wide in applicable scope.
Description
Technical field
The present invention relates to machining tool technical field, especially a kind of ceramic combination drill bit.
Background technology
Drill bit is the cutter for usually working under the working environment of high-speed rotation cutting, due to needing that Work piece high-speed is rotated
Cutting, this province of drill bit will produce amount of heat, and the general type of cooling is directly to be poured with brill with coolant, but due to boring
In high-speed rotation, coolant is highly susceptible to be got rid of winged in drilling bit high-speed rotation process head, it is impossible to completely attach to drill bit
Blade, cooling effect is bad, and wastes very much coolant.
The content of the invention
The technical problem to be solved in the present invention is：It is bad in order to solve existing drill bit cooling effect, and waste very much cold
But the problem of liquid, the invention provides a kind of ceramic combination drill bit, can in time be passed the heat of generation by metal fix bar
Brill body and drillstock are directed at, it is poor so as to efficiently solve the problems, such as ceramic bit radiating effect.
The technical solution adopted for the present invention to solve the technical problems is：A kind of ceramic combination drill bit, including drillstock, brill body
And drill bit, chisel edge is provided with the cutting blade for cutting, bores body and be provided with the rotational trajectory of cutting blade, two cutting blades
Chip area is formed between rotational trajectory, the drillstock is carbon steel drillstock, and the brill bores body as carbon steel, and the drill bit is ceramics
Drill bit, the brill body lower end is centrally formed with a metal fix bar, and the fix bar is coated on bit central, and will bore body and brill
Head is fixedly connected, and the fix bar runs through drill bit, and the lower end of fix bar forms the apex point of drill bit.
Ceramic combination drill bit can will directly bore body and drill bit blank is combined with each other, and then form by a firing.
In order to further strengthen the fixed fastness between fix bar and drill bit, the fixed bar side wall is fixed with some convex
Rise.
Preferably, the helical angle of the rotational trajectory is 30 ° -35 °.
Preferably, the drillstock is externally provided with frosted layer.
Specifically, the drill bit is silicon carbide ceramics drill bit.
The invention has the beneficial effects as follows：The invention provides a kind of ceramic combination drill bit, can be by by metal fix bar
The heat of generation is conducted in time to body and drillstock is bored, poor so as to efficiently solve the problems, such as ceramic bit radiating effect, structure letter
It is single, good cooling results, and this ceramic combination drill bit has excellent abrasion resistance properties, and long service life, range of application is wider.

Specific embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are simplified schematic diagram, only with
The basic structure of the illustration explanation present invention, therefore it only shows the composition relevant with the present invention.
As shown in Figure 1 to Figure 3, a kind of ceramic combination drill bit 3, including drillstock 1, brill body 2 and drill bit 3, the front end of drill bit 3 is provided with
For the cutting blade 4 of cutting, the rotational trajectory 5 that body 2 is provided with cutting blade 4 is bored, between the rotational trajectory 5 of two cutting blades 4
Chip area 6 is formed with, drillstock 1 is carbon steel drillstock, it is that carbon steel bores body to bore body 2, and drill bit 3 is ceramic bit, bores heart-shaped in the lower end of body 2
Cheng Youyi metals fix bar 7, fix bar 7 is coated on the center of drill bit 3, and is fixedly connected body 2 is bored with drill bit 3, and fix bar 7 runs through
Drill bit 3, the lower end of fix bar 7 forms the apex point 8 of drill bit 3.
In a kind of specific embodiment, it is contemplated that the stability in order to ensure combined drill, the side wall of fix bar 7 consolidate
Surely have some raised 9.
Preferably, the helical angle of rotational trajectory 5 is 30 ° -35 °.
Preferably, drillstock 1 is externally provided with frosted layer 10.
Preferably, drill bit 3 is silicon carbide ceramics drill bit.
With the above-mentioned desirable embodiment according to the present invention as enlightenment, by above-mentioned description, relevant staff is complete
Entirely various change and modification can be carried out in the range of without departing from this invention technological thought.The technology of this invention
Property scope is not limited to the content on specification, it is necessary to its technical scope is determined according to right.
