Abstract
The utility model provides a compound structure of boring of solid carbide, including boring the body and drillstock, the brill is personally experienced sth. Part of the body and is linked to each other with the drillstock, bores the body and includes fluted drill and spotter, and the spotter setting is put at the front end central point of fluted drill, and the shoulder of the link of fluted drill and spotter is equipped with one and mills the sword. Through set up a spotter at fluted drill front end central part, the spotter of front end plays location and guiding function to drilling on the one hand, can make the drill bit not have under the circumstances of preprocessing, and the light inclined plane of realizing is fixed a position and is holed, and on the other hand has combined fluted drill high -speed machining's advantage, and then has solved problem high -speed on the inclined plane, stable drilling, and it is stable to have improved machining efficiency and product to the position and the smooth finish of drilling have been guaranteed simultaneously.
Description
Technical field
This utility model is related to cutter manufacture field, more particularly to a kind of whole hard alloy composite drill structure.
Background technology
Existing fluted drill has the disadvantages that：One be each point on main cutting edge anterior angle change in value it is very big, be close to bore
It has been negative rake at core, machining condition is poor；Two is that chisel edge is oversize, has very big sword drift angle, has very big negative rake again, cutting
Condition is worse, thus axial direction drag is big, cutting energy consumption is big, easily skidding, it is impossible to quickly and accurately feel relieved.Therefore when drill bit exists
When directly drilling on the inclined-plane of workpiece, the position in hole easily trains off, and with the increase of bevel angle, the probability that fractures of drill bit
It is substantially increased, is that this generally mills out plane in the plane with milling cutter, allows drill bit and pierced with the plane perpendicular to preprocessing, but so
Slow down processing beat, considerably reduce work efficiency.
Utility model content
The purpose of this utility model is to provide a kind of whole hard alloy composite drill structure such that it is able to which effectively solving exists
Cutter life short problem when drilling on the inclined-plane of part.
For achieving the above object, the utility model proposes whole hard alloy composite drill structure, including drill body and drillstock,
The drill body is connected with the drillstock, before the drill body includes that fluted drill and pilot drill, the pilot drill are arranged on fluted drill
End center, the fluted drill are provided with a milling edge with the shoulder of the connection end of the pilot drill.
Further, in described whole hard alloy composite drill structure, the pilot drill is integrated into fluted drill
Shape.
Further, in described whole hard alloy composite drill structure, a diameter of described Flos Cannabiss of the pilot drill
The half of drill diameter.
Further, in described whole hard alloy composite drill structure, the bit tip angle of the pilot drill is 120 °.
Further, in described whole hard alloy composite drill structure, the drill body is fallen with the junction of drillstock
30°。
Compared with prior art, the beneficial effects of the utility model are：By arranging certain in fluted drill front end center portion
The heart is bored, and the pilot drill of one side front end plays positioning and guiding function to drilling, and enabling to drill bit is not having the feelings of preprocessing
Under condition, contour localization and drilling are easily realized, on the other hand combine the advantage of fluted drill High-speed machining, and then solve oblique
The problem at a high speed, stably drilled on face, improves working (machining) efficiency and product stability, and while ensure that position and the light of drilling
Cleanliness.
Description of the drawings
Fig. 1 is the schematic diagram of whole hard alloy composite drill structure in one embodiment of this utility model.
Specific embodiment
Whole hard alloy composite drill structure of the present utility model is described in more detail below in conjunction with schematic diagram,
Which show preferred embodiment of the present utility model, it should be appreciated that those skilled in the art can change described here reality
With new, and still realize advantageous effects of the present utility model.Therefore, description below is appreciated that for art technology
Personnel's is widely known, and is not intended as to restriction of the present utility model.
As shown in figure 1, the utility model proposes whole hard alloy composite drill structure, including drill body 1 and drillstock 2, institute
State drill body 1 to be connected with the drillstock 2, the drill body 1 includes fluted drill 3 and pilot drill 4, the pilot drill 4 is arranged on fluted drill 3
Front end center position, the fluted drill 3 is provided with a milling edge 5 with the shoulder of the connection end of the pilot drill 4.
Specifically, in the present embodiment, the pilot drill 4 is one of the forming with fluted drill 3.
Specifically, in the present embodiment, the half of 3 diameter of a diameter of described fluted drill of the pilot drill 4.
Specifically, in the present embodiment, the bit tip angle of the pilot drill 4 is α=120 °.
Specifically, in the present embodiment, β=30 ° are fallen in the junction of the drill body and drillstock.
To sum up, in the whole hard alloy composite drill structure that this utility model embodiment is provided, by before fluted drill
End central part arranges a pilot drill, and the pilot drill of one side front end plays positioning and guiding function to drilling, enables to drill bit
In the case of no preprocessing, contour localization and drilling are easily realized, on the other hand combine the excellent of fluted drill High-speed machining
Gesture, and then solve on inclined-plane at a high speed, the problem of stable drilling, working (machining) efficiency and product stability are improve, and while is protected
Position and the fineness of drilling are demonstrate,proved.
Preferred embodiment of the present utility model is above are only, any restriction effect is not played to this utility model.
Any person of ordinary skill in the field, in the range of without departing from the technical solution of the utility model, to this utility model
The technical scheme and technology contents of exposure makes the variation such as any type of equivalent or modification, belongs to without departing from this utility model
Technical scheme content, still fall within protection domain of the present utility model.
