Abstract
The utility model discloses a kind of elongated hole boring target drill, main body is drill body, and described drill body is made up of drill bit and drill body global formation, and its innovative point is: be provided with the some chip areas with axis being parallel at drill bit and drill body coupling part; Be starting point at drill body and drill bit junction, be circumferentially with a spiral chip area along drill body; Described some chip areas with axis being parallel be circumferentially with a spiral chip area along drill body and be connected.The utility model is mainly elongated hole drilling design, and because elongated hole boring requirement drill bit is deeply comparatively dark, chip removal is more difficult, therefore, the utility model adopts the combination of multiple chip removal mode, solves the problem of elongated hole boring chip removal difficulty, reduce the generation of heat during boring, extend bit life.
Description
Technical field
The utility model relates to a kind of drill bit, specifically a kind of elongated hole boring target drill.
Background technology
Drill bit, as the indispensable instrument of boring, is engineer's common tool; The form of drill bit is more, and purposes is comparatively wide, and the pass having boring is also more.Because boring is according to the requirement of pass, the requirement of sheet material, there is different drill bit design requirements.Various informative.At present, although market drill bit is more, there are no elongated hole boring target drill of the present utility model.
Utility model content
The utility model mainly provides a kind of elongated hole boring target drill, solve open long hole shape drill bit cannot chip removal, the problem in warming-up effect life-span.
In order to solve above technical problem, the utility model provides following scheme:
A kind of elongated hole boring target drill, main body is drill body, and described drill body is made up of drill bit and drill body global formation, and its innovative point is:
The structure of described drill bit is cone, and the structure of drill body is cylinder;
The some chip areas with axis being parallel are provided with at described drill bit and drill body coupling part; Be starting point at drill body and drill bit junction, be circumferentially with a spiral chip area along drill body;
Described some chip areas with axis being parallel be circumferentially with a spiral chip area along drill body and be connected.
Further, also equidistantly on described drill body annular chip area is provided with.
Beneficial effect: the utility model is mainly elongated hole drilling design, because elongated hole boring requirement drill bit is deeply comparatively dark, chip removal is more difficult, therefore, the utility model adopts the combination of multiple chip removal mode, solves the problem of elongated hole boring chip removal difficulty, reduce the generation of heat during boring, extend bit life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
A kind of elongated hole of one of the present utility model boring target drill, structure as shown in the figure: main body is drill body, and described drill body is made up of drill bit 1 and drill body 2 global formation, and concrete structure is as follows:
The structure of drill bit 1 of the present utility model is cone, and the structure of drill body 2 is cylinder.The some chip areas 3 with axis being parallel are provided with at drill bit 1 and drill body 2 coupling part; Be starting point at drill body 2 with drill bit 1 junction, be circumferentially with a spiral chip area 4 along drill body; With some chip areas 3 of axis being parallel be circumferentially with a spiral chip area 4 along drill body and be connected.This structure efficiently solves chip removal problem, particularly for darker hole, by first carrying out chip removal along axis, and then follows turning to of drill bit, forms the chip removal of helical type.Get into depths to solve drill bit, the smooth problem of the chip removal at drill body place, the utility model is still provided with some equidistant annular chip areas 5 on drill body, effectively solves blockage problem, prevents drill bit because of the freely not overheated phenomenon of chip removal.
