Abstract
The invention discloses a worm type drill capable of cooling automatically. The worm type drill capable of cooling automatically comprises a drill body and a screw rod, the drill body is arranged on the screw rod, a cooling pipeline is arranged in the screw rod, a water inlet pipe and a water discharge pipe are arranged at the left end of the screw rod, cooling liquid enters the cooling pipeline through the water inlet pipe, and the cooling liquid is discharged from the cooling pipeline through the water discharge pipe. The cooling liquid is filled into the screw rod through the cooling pipeline in the screw rod to cool the drill body and screw rod from the inside and outside, and moreover, the blade trench is parabolic trough-shaped, the space of a spiral groove is fully increased so as to facilitate chip removal, the chip removal resistance is reduced, the working efficiency is improved, and the service life of the drill is prolonged.
Description
Technical field
The present invention relates to a kind of drill bit, particularly relate to a kind of worm drill bit automatically can lowered the temperature from inside.
Background technology
When rig works, because drill bit and material rub, can produce very high temperature, damage is caused to drill bit, and common cool-down method uses cutting fluid to spray drill hole, drill bit is lowered the temperature, and drill hole is lubricated, but due to the heating of drill bit entirety, and cutting fluid is only lowered the temperature from outside, drill bit internal and external temperature can be caused different, cause the damage of drill bit.Therefore, uneven problem of lowering the temperature when solving bit operation just seems particularly important.
Summary of the invention
The invention provides and a kind ofly can carry out the worm drill bit of lowering the temperature from drill bit internal, by being arranged on the cooling pipeline of drill bit internal, making cooling fluid enter drill bit internal, drill bit being lowered the temperature from inside and outside simultaneously, uneven problem of lowering the temperature when solving bit operation.
The object of this invention is to provide a kind of worm drill bit that can automatically lower the temperature, comprise drill bit and screw rod, described drill bit is arranged on screw rod, described inside screw is provided with cooling pipeline, screw rod left end is provided with water inlet pipe and outlet pipe, cooling fluid enters in cooling pipeline by water inlet pipe, discharges cooling pipeline by outlet pipe.
Further improvement is: the flute of described drill bit is parabola flute profile, and brill core thickeies and removes the thickness of sword lobe, bores core and thickeies thickness and remove sword lobe consistency of thickness.
Further improvement is: described cooling pipeline is that the adiabator of resistance to thermal conductance is made.
Beneficial effect of the present invention: by being arranged on the cooling pipeline of inside screw, cooling fluid is passed into inside screw, from inside and outside, drill bit and screw rod are lowered the temperature, and flute is made parabola flute profile, abundant increase helicla flute space is so that chip removal, reduce chip removal resistance to increase work efficiency, extend the service life of drill bit.
Accompanying drawing explanation
Fig. 1 is structural perspective of the present invention.
Fig. 2 is drill bit sectional view of the present invention.
Wherein: 1-drill bit, 2-screw rod, 3-lowers the temperature pipeline, 4-water inlet pipe, 5-outlet pipe.
Detailed description of the invention
In order to deepen the understanding of the present invention, below in conjunction with embodiment, the invention will be further described, and this embodiment only for explaining the present invention, does not form limiting the scope of the present invention.
As shown in Figure 1, 2, present embodiments provide a kind of worm drill bit that can automatically lower the temperature, comprise drill bit 1 and screw rod 2, described drill bit 1 is arranged on screw rod 2, described screw rod 2 inside is provided with cooling pipeline 3, screw rod 2 left end is provided with water inlet pipe 4 and outlet pipe 5, and cooling fluid enters in cooling pipeline 3 by water inlet pipe 4, discharges cooling pipeline 3 by outlet pipe 5.The flute of described drill bit 1 is parabola flute profile, and brill core thickeies and removes the thickness of sword lobe, bores core and thickeies thickness and remove sword lobe consistency of thickness.Described cooling pipeline 3 is made for the adiabator of resistance to thermal conductance.Bore core suitably thicken and remove part sword lobe, total length is bored core thickness constant.Sharp angle
°, and add large helix angle (
~ 40 °), flute face is through polishing.This Worm type drill bit is also suitable for the hole of drill steel material comparatively dark (L/d≤20), and chip removal is good, and adopt cross sharpening, durability is higher.By being arranged on the cooling pipeline 3 of screw rod 2 inside, cooling fluid is passed into screw rod 2 inner, from inside and outside, drill bit 1 and screw rod 2 are lowered the temperature, and flute is made parabola flute profile, abundant increase helicla flute space is so that chip removal, reduce chip removal resistance to increase work efficiency, extend the service life of drill bit.
