Description
Technical field
The utility model is related to a kind of drill bit for being useful in machining center or high precision numerical control drilling machine, for processing shallow bore hole,
Belong to a kind of drilling tool.
Background technology
The drilling tool of processing shallow bore hole is typically all bradawl in the prior art, and be all high speed drill, it is necessary to material hardness ratio
It is larger, typically all noble metal, because being integrally formed, its manufacturing cost is just higher, occurs to solve this problem
Shallow hole drilling, the matrix of shallow hole drilling is common metal, and its cutting edge is hard alloy, and hard alloy is arranged on matrix, for point
The structure of body formula, saves cost, but, hard alloy is fixed on matrix generally by the mode of welding, it is impossible to torn open
Dress, the scope of application is narrower.
Utility model content
The purpose of this utility model is to provide a kind of shallow hole drilling, to solve the carbide cutter tool of shallow hole drilling of the prior art
The problem that piece cannot be dismantled.
In order to realize the above object the utility model is adopted the following technical scheme that：A kind of shallow hole drilling, including integral type sheet
Body, is convexly equipped with positioning convex ring on the outer peripheral face of body, body is on the outer peripheral face of the drillstock part of positioning convex ring side to be had
Symmetrically arranged mounting plane, the bit part that body is in positioning convex ring opposite side is by two sections of circular arcs with two sliver transvers sections
The helical form chip area of the curve being formed by connecting, two helical form chip areas are respectively provided with two cutting shapes near the part of bit point of the drill
Into plane, two planes be in helical form chip area two side on and at the bottom land of helical form chip area intersect, two spiral shells
Revolve correspondence in a plane of shape chip area and be fixed with carbide chip, carbide chip is embedded in body and by spiral shell
Nail is fixed.
Described carbide chip is triangle sheet.
Outer Cooling Holes are provided with the outer peripheral face at described bit part tip, outer Cooling Holes are cold by being arranged in body
But passage is connected with the inlet on drillstock end face.
The sophisticated end face of described bit part is provided with interior Cooling Holes, and interior Cooling Holes are logical by being arranged on cooling in body
Road is connected with the inlet on drillstock end face.
Carbide chip of the present utility model is screwed on body, can be dismantled, and is selected as needed
Whether carbide chip is loaded onto, after abrasion occurs in carbide chip, in that context it may be convenient to change.
Outer Cooling Holes are provided with the outer peripheral face at bit part tip of the present utility model, outer Cooling Holes in body by setting
Put and connected with the inlet on drillstock end face in cooling duct, coolant, good cooling results, Ke Yida can be passed through in body
To cutting speed higher.
The sophisticated end face of the utility model bit part is provided with interior Cooling Holes, and interior Cooling Holes are cold by being arranged in body
But passage is connected with the inlet on drillstock end face, further enhances cooling effect, the good cooling results of product, service life
It is long.
Brief description of the drawings
Fig. 1 is the overall structure diagram of the utility model embodiment.
Specific embodiment
A kind of embodiment of shallow hole drilling, in Fig. 1, its body 1 is integral type, one-shot forming, a kind of material, without spelling
Connect, positioning convex ring 2 is convexly equipped with the outer peripheral face of body 1, the body part of the side of positioning convex ring 2 is drillstock part, opposite side
Part be bit part, can be with two mounting planes 3 on the outer peripheral face of drillstock part, two mounting planes 3 are in drill shank
It is symmetrical arranged on point.Bit part has two helical form chip areas 4, and the cross section of helical form chip area 4 is by two sections of circular arcs
The curve being formed by connecting, the curve is presented channel-shaped on the whole, and two helical form chip areas 4 are respectively provided with two near the part of bit point of the drill
The plane 5 that individual cutting is formed, the plane that so-called cutting is formed refers to carrying out cutting work on the cell wall of two helical form chip areas 4
Industry cuts out two planes, on two two sides of the plane 5 in the helical form chip area 4 on a helical form chip area 4, and
And, two planes 5 intersect at the bottom land of corresponding helical form chip area 4, are fixed with a plane of two helical form chip areas 4
Carbide chip 6, carbide chip 6 is triangle sheet, is embedded in body 1, that is, opened up on body 1
One groove being coincide with the shape of carbide chip 6, carbide chip 6 is embedded in the groove, also, carbide chip
6 are fixed on body 1 by screw 7, have the counterbore sunk to for the ailhead of the screw 7 on carbide chip 6, should
Screw is soket head cap screw.
Outer Cooling Holes 8 are offered on the sophisticated outer peripheral face of bit part, outer Cooling Holes 8 in body by being arranged on cooling
Passage is connected with the inlet on drillstock end face.
The sophisticated end face of bit part is provided with interior Cooling Holes 9, and interior Cooling Holes 9 in body 1 by being arranged on cooling duct
Connected with the inlet on drillstock end face.
The cross section of the helical form chip area of the present embodiment is the curves of two arcs composition, cutting chip be cut with
Afterwards as a camber line is turned over to core, promote cutting chip leave raw material as early as possible, when cutting chip leave raw material with
Afterwards will enter another camber line formed space, accommodate, discharge cutting chip space it is larger, also can conveniently, agile row
Bits, accelerate cutting speed, are also prevented from drilling tool and cutting chip friction, extend the life-span of drilling tool, also, workpiece is processed in raising
Quality.
Outer Cooling Holes and interior Cooling Holes are provided with the present embodiment, in other embodiments, if cutting speed is not too
It is high, it is also possible to be not provided with.
