Abstract
The utility model provides a minor diameter solid carbide drill gun which belongs to the dark hole machining tool technical field of metal cutting. This drill gun includes handle, drilling rod connecting piece, drilling rod and drill bit, and the drilling rod is made for solid carbide with the drill bit, is the diameter of drill bit 1.2 2mm. Set up drill bit inclined plane and circle sword on the drill bit. The little demand that satisfies the minor diameter BTA of diameter of this drill gun, this drill gun adopt the carbide integration, have improved the hardness of drill gun, have widened the durometer level of treating processing material, are fit for the large -scale industry and promote.
Description
Technical field
This utility model is related to a kind of minor diameter whole hard alloy drill gun, and which belongs to metal cutting deep hole processing cutter skill
Art field.
Background technology
Drill gun is a kind of deep hole drilling cutter, is used exclusively for the processing of gun barrel earliest, adds for standard machinery afterwards
Work, has a long history.Drill gun can be with drilling draw ratio up to 100：1 deep hole, adding aiding support can drilling 200：1 depth
Hole.The cutting speed of carbide gun drill is 4-5 times of high speed steel twist drill, and once can be drilled through without withdrawing, the hole of processing
With higher dimensional accuracy and surface accuracy, drill gun is a kind of economic and practical, reliable efficient deep hole processing cutter.Drill gun is also
Can be used for the processing of general shallow bore hole, fluted drill is substituted in production in enormous quantities to improve working (machining) efficiency.Drill gun mainly should at present
For the processing of the deep hole of a diameter of 2-30mm, diameter rarely has application as drill gun manufacture is difficult less than the deep hole of 2mm.
The content of the invention
To solve problems of the prior art, this utility model provides a kind of minor diameter rifle of a diameter of 1.2-2mm
Bore, i.e., minor diameter drill gun is manufactured with whole hard alloy, to adapt to the demand of Machining Small-deep Hole.
The technical solution adopted in the utility model is：A kind of minor diameter whole hard alloy drill gun, it includes handle and brill
Joint element for bar, the drill gun also include drill bit and drilling rod, are provided with Cooling Holes in drilling rod and drill bit.The drilling rod inserts drilling rod connector
In handle, chip area between the first plane and the second plane, is constituted, the end of the drill bit is provided with the first inclined-plane, second oblique
Face, the 3rd inclined-plane and the 4th inclined-plane, the first inclined-plane are 40 degree with the angle of vertical plane, and the second inclined-plane is 30 with the angle of vertical plane
Degree, the 3rd inclined-plane are 35 degree with the angle of vertical plane, and the 4th inclined-plane is 15 degree with the angle of horizontal plane；Circle is additionally provided with drill bit
Sword, circle blade surface are 15 degree with the angle of horizontal plane.
A diameter of 1.2-2mm of the drill bit.
The beneficial effects of the utility model are：The drill gun includes handle, drilling rod connector, drilling rod and drill bit, drilling rod and brill
Head is made up of whole hard alloy, a diameter of 1.2-2mm of drill bit.Drill bit inclined-plane and circle sword are set on drill bit.The drill gun it is straight
The little demand for meeting Machining Small-deep Hole in footpath, the drill gun are improve the hardness of drill gun, are widened using hard alloy integration
The hardness range of material to be processed, shortens process time, is adapted to large-scale industry and promotes.
