Description
Technical field
The utility model is related to building implement field, more particularly to a kind of quick inequilateral bores.
Background technology
Drill bit is the Common Use Tools of drilling and reaming, and drill bit mainly cuts workpiece by bit tip in drilling
It cuts, is discharged chip by chip space, if the discharge that chip cannot be much smoother, the hole inner wall bored can be caused cut occur,
Workpiece is even resulted in as waste product, when drill bit designs, the shape and structure of chip space will directly affect speed and the row of its chip removal
The effect let out.The shape and structure of bit point of the drill cutter head also determine drill bit positioning and the speed cut.
Existing drill bit, generally there are following shortcomings：It is combined by two sections of materials, meeting generating material breaks during use
It splits；Groove profile is original, is unfavorable for draining；Soldering is unqualified, hard alloy can be made to drop；Hard alloy shape is for punching very
Arduously.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of general-purpose brills, bore body groove profile by changing, make it
More easily drain, while the integral brill body of brill body improvement that two sections of original combinations of materials are formed, it adds and bores body
Anti-strike capability.
Technical problem to be solved in the utility model is achieved through the following technical solutions：
A kind of quick inequilateral bores, including drilling rod and the active section for being arranged at the drilling rod front end, the active section it is upper
Spiral helicine chip space is offered, the groove profile of the chip space is L shape, the front end of the active section is provided with drill bit, institute
The rear end for stating drilling rod is provided with connecting portion.
Preferably, in above-mentioned technical proposal, the head angle of the drill bit is 105 degree.
Preferably, in above-mentioned technical proposal, the section of the connecting portion is hexagon.
Preferably, in above-mentioned technical proposal, the section of the connecting portion is equilateral hexagon.
Preferably, in above-mentioned technical proposal, the drill bit is reverse V-shaped structure.
Preferably, in above-mentioned technical proposal, the connecting portion is wholely set with the drilling rod.
Compared with prior art, the utility model above-mentioned technical proposal has the advantages that：
(1) change hard alloy shape, make it use among process can be more quick, it is convenient, it is laborsaving.
(2) change thread shape, it is made more easily to drain, it can be more laborsaving in practical operation.
(3) the welding fastness of hard alloy and drilling rod is added, it can be more durable
(4) the integral anti-strike energy for boring body, adding brill body of brill body improvement formed two sections of original combinations of materials
Power, so as to increase the service life.
(5) the original zinc-plated Shot Blasting till now of outer surface reason, it is more environmentally-friendly.
(6) afterbody hexagon, it is not in slide to bore rifle and hold.

Specific embodiment
Specific embodiment of the present utility model is described in detail below, it is new in order to further understand this practicality
Type.
Fig. 1 is the front view that the quick inequilateral of the utility model bores.The front view of the drill bit of Fig. 2 positions the utility model.
Fig. 3 is the top view of the drill bit of the utility model.The B-B sectional views that the quick inequilateral that Fig. 4 is Fig. 1 bores.Fig. 5 is new for this practicality
The schematic diagram for the connecting portion that the quick inequilateral of type bores.As shown in the figure：
A kind of quick inequilateral bores, including drilling rod 1 and the active section 2 for being arranged at 1 front end of drilling rod.Specifically：
Spiral helicine chip space 4 is offered on active section 2, the groove profile of chip space 4 is L shape, in the front end of active section 2
Drill bit 5 is provided with, the rear end of drilling rod 1 is provided with connecting portion 3.Angle setting is to make stress less.The excretion of L shape
Slot so that stress is few, and excretion is fast, and draining effect is good.
Preferably, drill bit 5 is reverse V-shaped structure.The head angle of drill bit 5 is 105 degree.Certainly, the utility model not with
This is limited, and those skilled in the art can select the setting of other shapes and angle as needed.
Preferably, the section of connecting portion 3 is hexagon.It is highly preferred that it is equilateral hexagon.The structure so that boring rifle is pressing from both sides
It is more secured when tight, it will not cause to slide.Certainly, the utility model is not limited thereto, and those skilled in the art can be according to need
Select other shapes.
Preferably, drill bit 5 is reverse V-shaped structure.Preferably, connecting portion 3 is wholely set or welds setting with drilling rod 1.
The cemented carbide material that the material selection Zhoushan of the utility model flies up to Tools Co., ltd's production is processed system
Make, by changing hard alloy shape, make it use can be more quick among process, it is convenient, it is laborsaving.The utility model leads to
Change thread shape is crossed, it is made more easily to drain, it can be more laborsaving in practical operation.Meanwhile add hard conjunction
The welding fastness of gold and drilling rod, can be more durable.The integral brill of brill body improvement that two sections of original combinations of materials are formed
Body adds the anti-strike capability for boring body, so as to increase the service life.At the original zinc-plated ball blast till now of outer surface reason
Reason, it is more environmentally-friendly.Afterbody hexagon, it is not in slide to bore rifle and hold.
Although the utility model is disclosed as above with embodiment, so it is not intended to limit the utility model, any ability
Field technique personnel without departing from the spirit and scope of the utility model, can make a variety of selections and modification, therefore this
