Description
Technical field
The utility model is related to machining tool technical field, especially a kind of ceramic combination drill bit.
Background technology
Drill bit is the cutter usually worked under the working environment that high-speed rotation is cut, 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 coolant with brill, but due to boring
Head is in high-speed rotation, and coolant is highly susceptible to be got rid of winged in drilling bit high-speed rotation process, it is impossible to completely attaches to and arrives drill bit
Blade, cooling effect is bad, and wastes very much coolant.
Utility model content
The technical problems to be solved in the utility model is:It is bad in order to solve existing drill bit cooling effect and very unrestrained
The problem of taking coolant, the utility model provides a kind of ceramic combination drill bit, can be by the heat of generation by metal fix bar
Amount conduction in time is to body and drillstock is bored, so as to efficiently solve the problem of ceramic bit radiating effect is poor.
The utility model solves the technical scheme that its technical problem used:A kind of ceramic combination drill bit, including drillstock,
Body and drill bit are bored, chisel edge is provided with the cutting blade for cutting, bore the rotational trajectory that body is provided with cutting blade, two bites
Chip area is formed between the rotational trajectory of sword, the drillstock is carbon steel drillstock, and the brill bores body as carbon steel, and the drill bit is
Ceramic 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
It is fixedly connected with drill bit, the fix bar runs through drill bit, 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 to be combined with each other, and then form by a firing.
In order to further strengthen the fixation 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 beneficial effects of the utility model are:The utility model provides a kind of ceramic combination drill bit, is fixed by metal
Bar can be by the conduction in time of the heat of generation to body and drillstock is bored, so as to efficiently solve asking for ceramic bit radiating effect difference
Topic, simple in construction, good cooling results, and this ceramic combination drill bit have excellent abrasion resistance properties, long service life, application
Scope is wider.

Embodiment
The utility model is described in further detail presently in connection with accompanying drawing.These accompanying drawings are simplified schematic diagram,
Only illustrate basic structure of the present utility model in a schematic way, therefore it only shows the composition relevant with the utility model.
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, bore between the rotational trajectory 5 that body 2 is provided with cutting blade 4, 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 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.
Using it is above-mentioned according to desirable embodiment of the present utility model as enlightenment, pass through above-mentioned description, related work people
Member can carry out various changes and amendments in the range of without departing from this utility model technological thought completely.This reality
The content on specification is not limited to new technical scope, it is necessary to its technology is determined according to right
Property scope.
