Description
Technical field
The utility model is related to building implement field, more particularly to a kind of general-purpose 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：Hard alloy uses the complete import of Luxembourg's blade, is monopolized, valency
Lattice are expensive；Drilling rod groove profile, excretion be not quick；Drill bit is relatively elaborate when in use, and artificial usage time is long, and wrist can ache；It closes
The weld of gold and drilling rod, degree of adhesion is inadequate, and bit life is not grown；Bit face processing is not environmentally.
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, can be more laborsaving in practical operation, alloy head inclined-plane in addition, preferably help drill bit positioning with
Quickly cut.
Technical problem to be solved in the utility model is achieved through the following technical solutions：
A kind of general-purpose bores, and including drilling rod and the active section for being arranged at the drilling rod front end, spiral shell is offered on the active section
The chip space of shape is revolved, the groove profile of the chip space is L shape, and drill bit is provided in the front end of the active section, the drill bit
Head angle is 125-135 degree.
Preferably, in above-mentioned technical proposal, the head of the drill bit has the inclined surface of polymorphic structure.
Preferably, in above-mentioned technical proposal, the head angle of the drill bit is 130 degree.
Preferably, in above-mentioned technical proposal, the drilling rod afterbody angle is 115-125 degree.
Preferably, in above-mentioned technical proposal, the drilling rod afterbody angle is 120 degree.
Preferably, in above-mentioned technical proposal, the length of the active section is 40-80mm.
Preferably, in above-mentioned technical proposal, the length of the active section is 60mm.
Compared with prior art, the utility model above-mentioned technical proposal has the advantages that：
(1) the utility model uses hard alloy, which is independently our company's independent research, can be large batch of
This phenomenon that must be brought by import has been broken in domestic production；
(2) body groove profile is bored by changing, 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) general-purpose of the utility model bores, from original special purpose, multiple operating environments till now, it now is possible to
In steel, polished bricks, glass carries out process operation on wood；
(5) the original zinc-plated Shot Blasting till now of outer surface reason, it is more environmentally-friendly.
(6) alloy head inclined-plane preferably helps drill bit positioning with quickly cutting.
Description of the drawings
Fig. 1 is the schematic diagram that the general-purpose of the utility model bores.
The A-A sectional views that the general-purpose that Fig. 2 is Fig. 1 bores.
Fig. 3 is the drill bit schematic diagram that the general-purpose of the utility model bores.
Wherein：1- drilling rods, 2- active sections, 3- chip spaces, 4- drill bits.
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 schematic diagram that the general-purpose of the utility model bores.The A-A sectional views that the general-purpose that Fig. 2 is Fig. 1 bores.Fig. 3 is this reality
The drill bit schematic diagram bored with new general-purpose.As shown in the figure：
A kind of general-purpose bores, including drilling rod 1 and active section 2.Preferably, drilling rod 1 and active section 2 are integrated setting or welding is set
It puts.
Spiral helicine chip space 3 is offered on active section 2.As shown in Fig. 2, the groove profile of the chip space 3 of the utility model is L
Shape, the groove profile running speed of L shape is faster and for minimum.
The front end of active section 2 is provided with drill bit 4, it is preferable that the drill bit 4 that the utility model uses for special construction,
Head is made of the inclined surface of multiple polymorphic structures.
The head angle of drill bit 4 is 125-135 degree.Preferably, the head angle of drill bit 4 is 130 degree.Certainly, this practicality
It is new to be not limited thereto.
1 afterbody angle of drilling rod is 115-125 degree.Preferably, 1 afterbody angle of drilling rod is 120 degree.
The length of active section 2 is 40-80mm.Preferably, the length of active section 2 is 60mm.Certain the utility model is not
As limit.
The general-purpose of the utility model bores, the preferred hard alloy that Tools Co., ltd's production is flown up to using Zhoushan.The conjunction
Gold is independent research, avoids import Luxembourg blade, raw material are more convenient, while reduce the expense of production, groove profile shape
The change of shape makes it more easily drain, can be more laborsaving in practical operation；Due to special material and special shape
Cooperation so that general-purpose brill avoids the special purpose of tradition brill, it now is possible to which in steel, polished bricks, glass is added on wood
Work operates；In finished product production, alignment outer surface carries out Shot Blasting, which obviates original zinc-plated processing, more environmentally-friendly；It closes
Golden head portion inclined-plane preferably helps drill bit positioning with quickly cutting.
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
The protection domain of utility model is limited by claims and its equivalents.
