Description
Technical field
The utility model is related to a kind of flat-wing driller.
Background technology
The shortcoming that existing flat-wing driller is primarily present is:One is due to being provided with main cutting edge and circumference cutting on drill bit
Sword, but lack the passage of corresponding discharge scrap, the scrap for being susceptible to two cutting edge cutting generations mutually produces interference;
Two is to lack the structure setting for reducing stress concentration degree between drill bit and drilling rod so that in the course of the work drill bit and drilling rod it
Between junction easily there is stress concentration phenomenon, be easily caused drilling rod and rupture, so as to reduce service life.
Content of the invention
The technical problem that the utility model is solved is the defect for overcoming prior art, there is provided one kind adopts integral structure
Design cause bulk strength is higher, fixing is more preferable, service life is longer and cutting resistance is less in boring procedure, move back bits and
The higher flat-wing driller of chip removal ability.
In order to solve above-mentioned technical problem, the utility model is addressed by following technical proposals:
Flat-wing driller, including drilling rod, is fixedly installed on the drill bit of drilling rod front end, is fixedly installed on the drillstock of drilling rod rear end, bores
Head includes being fixedly installed on the drill body of drilling rod front end, being fixedly installed on the apex point of drill body head face center, and drill body is respectively equipped with
The main cutting edge being connected as a single entity with drill body and circumferential cutting edge, main cutting edge are laid by the Inside To Outside in drill body head face, circle
All cutting edges are arranged at the outer rim in drill body head face, are provided between main cutting edge and the inclined-plane that is arranged on the inside of drill body head face
Bit-withdrawing slot, circumferential cutting edge and be arranged at drill body head face outer rim circular arc cutting face between be formed with chip area.Using one
Formula structure design so that bulk strength is higher, fixing is more preferable, service life is longer, by being respectively provided with master in chisel edge
Cutting edge and circumferential cutting edge and its corresponding bit-withdrawing slot and chip area so that in boring procedure, cutting resistance is less, move back
Bits and chip removal ability are higher, and the flat-wing driller structure is simpler, are integrally formed that working (machining) efficiency is higher and cost is relatively low.
Preferably, drill bit, drilling rod, drillstock are connected as a single entity successively.
Preferably, apex point is connected as a single entity with drill body.
Preferably, the profile of apex point is pyramid shape.
Preferably, drilling rod front end end is provided with arc-shaped transitional surface, contribute to reducing drilling rod in the course of work with drill bit company
Meet place and stress concentration degree occurs, it is to avoid drilling rod ruptures, and improves service life.
Preferably, locating slot is provided between drilling rod rear end and drillstock front end, improve the positioning function in the course of work.
The utility model as a result of above technical scheme, with significant technique effect:Set using integral structure
Meter so that bulk strength is higher, fixing is more preferable, service life is longer, by chisel edge be respectively provided with main cutting edge and
Circumferential cutting edge and its corresponding bit-withdrawing slot and chip area so that in boring procedure, cutting resistance is less, move back bits and chip removal
Ability is higher, and the flat-wing driller structure is simpler, is integrally formed that working (machining) efficiency is higher and cost is relatively low.
