Abstract
The utility model discloses a kind of self-cooleds to slide drill bit.What it included opening up on drill body and drill body moves towards the helicla flute to be formed along drill body spiral, the edge of helicla flute forms cutting edge, the end of drill body is provided with positioned at the locating tip at drill body center and locating tip both sides by being located at the cutting point that cutting edge end tip is formed, the arc milling blade of indent is formed between locating tip and cutting point, drill body is provided centrally with along the longitudinally disposed cooling duct of drill body, cavernous body is mounted in cooling duct, fluid hole is distributed on helicla flute, there is the branched bottom for connecting each fluid hole on cooling duct.With the above structure, in process coolant by fluid hole can be flowed out and realize refrigerating function, cooling effect is very good, and improves out liquid effect by the damping action of cavernous body, so as to improve cooling effect, it ensure that processing quality and improve processing efficiency.
Description
Technical field
The utility model is related to a kind of machining tool, specifically a kind of self-cooled slides drill bit.
Background technology
It is generally punched in carpenter's cutting operation using cut drill, traditional cut drill generally comprises to drill
Drill bit and head cutting edge, in use, by cutting edge treat cutting workpiece carry out machining, traditional this knot
Structure can get circular hole on workpiece to be processed, but since drill bit is to operate in high-speed rotating workplace, can cut
It cuts and a large amount of heat is generated in process, be typically all traditionally that work is further continued for after drill bit cooling by the mode of being stopped
The operating process of work is placed on drill bit the mode cooled down in cold water and is cooled down, although this mode plays certain effect
Fruit, but it is time-consuming and laborious that artificial reciprocating operation is used to cool down, and not only affects final cutting effect and also reduces processing efficiency.
Invention content
The technical problem to be solved by the utility model is to provide a kind of machining effect is good, cooling velocity is fast and processes
Efficient self-cooled slides drill bit.
In order to solve the above-mentioned technical problem, the self-cooled of the utility model slides drill bit, including drill body and drill bit sheet
What is opened up on body moves towards the helicla flute to be formed along drill body spiral, and the edge of helicla flute forms cutting edge, the end of drill body
End is provided with the cutting formed positioned at the locating tip at drill body center and locating tip both sides by being located at cutting edge end tip
Point, forms the arc milling blade of indent between locating tip and cutting point, drill body is provided centrally with indulging along drill body
To the cooling duct of setting, cavernous body is mounted in cooling duct, fluid hole is distributed on helicla flute, has on cooling duct and connects
Lead to the branched bottom of each fluid hole.
The branched bottom tilts extension from cooling duct along the drilling direction of drill bit.
The drill body is made of high-speed tool Steel material.
After above-mentioned structure, due to the centrally disposed cooling duct for being mounted with cavernous body of drill body and spiral
The fluid hole being distributed on slot it is possible thereby to add in coolant in cooling duct in going to for cutting, can make cold in process
But liquid is flowed out by fluid hole realizes refrigerating function, and drill bit is thus no longer needed to be placed on cooling reduction temperature, cooling in cold water
Effect is very good, completely solves existing technical barrier, and improve out liquid effect by the damping action of cavernous body
Fruit so as to improve cooling effect, ensure that processing quality and improve processing efficiency.
Description of the drawings
Fig. 1 is the structure diagram that the utility model self-cooled slides drill bit.
Specific embodiment
With reference to the accompanying drawings and detailed description, drill bit is slided to the self-cooled of the utility model to make further specifically
It is bright.
As shown in the figure, the self-cooled of the utility model slides drill bit, including the edge opened up on drill body 1 and drill body
Drill body spiral moves towards the helicla flute to be formed 2, and drill body 1 is preferentially made of high-speed tool Steel material, helicla flute
Edge forms cutting edge 3, and the end of drill body 1 is provided with positioned at the locating tip 4 at drill body center and locating tip both sides
The cutting point 5 formed by being located at 3 distal tip of cutting edge forms the arc milling blade of indent between locating tip 4 and cutting point 5
6, it can be made to carry out machining to ligneous piece with this configuration, drill body 1 is provided centrally with along drill body longitudinal direction
The cooling duct 7 of setting is mounted with cavernous body 8 in cooling duct 7, fluid hole 9 is distributed on helicla flute 2, fluid hole makes to obtain
Liquid is uniform, improves the uniformity of cooling, has the branched bottom for connecting each fluid hole on cooling duct 7.
Further, described branched bottom is tilted along the drilling direction of drill bit from cooling duct 4 and is extended, that is,
Saying can be such that coolant is thrown away in drilling process by the rotary force of drilling by the inclined design of branched bottom, thus into one
Step ensure that out liquid effect, and in addition it can which fluid hole 6 to be designed as to larger placement hole, liquid valve is disposed in placement hole,
Certain liquid valve can be removed and installed by thread forms installation, provide a kind of maintenance means.
