Abstract
A kind of hog nose needle construction, comprise body, with the drill lip portion of described body on same axis and the connecting portion being connected described body and drill lip portion, the end in described drill lip portion is provided with apex point cutting edge, the outer surface in described drill lip portion is provided with a chip chip area, and described chip chip area is extended spirally to connecting portion by the end in drill lip portion; Described connecting portion is coniform and taper seat becomes 15 ° with the axis of rotation of described body, and the length of described connecting portion is less than the length of described drill lip portion and body.Hog nose needle construction of the present utility model is by changing PCB drill point structure, the cross-sectional area of brill core is increased greatly, thus improve the integral rigidity intensity of drill point, not only can make drill point sword extended length, and the rigidity of drill point can also be made also to improve greatly, thus add boring lamination number and the drilling hole amount of boring, reach and enhance productivity, the object reduced costs.
Description
Technical field
The utility model relates to printed substrate machining field, particularly relates to a kind of hog nose needle construction.
Background technology
In information computerization industry fast-developing today, industry of printed circuit boards obtains the development of advancing by leaps and bounds, and various printed substrate emerges in an endless stream, and traditional PCB (Printed circuit board) drill point has not adapted to the demand in market.Traditional PCB drill point structure is: two chip discharge ditches, is the same structure with the fluted drill that we see usually, and namely two chip discharge ditches extend to from two faces of drill bit top symmetry and bore bottom body, relatively do not contact all the time.Boring two limits of core, this type of drill point structure shortcoming is: the cross-sectional area boring core is little, and the rigid of drill point is not enough, and drill point easily produces under the circumference of the high-speed rotation and splits off.
Utility model content
Technical problem to be solved in the utility model is, provides a kind of hog nose needle construction, improves the integral rigidity intensity of drill point, solves the problem that user increases boring lamination number and drilling hole amount, reaches and enhance productivity, the object reduced costs.
A kind of technical scheme realizing above-mentioned purpose is: a kind of hog nose needle construction, comprise body, with the drill lip portion of described body on same axis and the connecting portion being connected described body and drill lip portion, the end in described drill lip portion is provided with apex point cutting edge, the outer surface in described drill lip portion is provided with a chip chip area, and described chip chip area is extended spirally to connecting portion by the end in drill lip portion; Described connecting portion is coniform and taper seat becomes 15 ° with the axis of rotation of described body, and the length of described connecting portion is less than the length of described drill lip portion and body.
As the improvement of technique scheme, the length of described chip chip area is 5.5mm to 5.8mm.
As the improvement of technique scheme, the limit cutter of described apex point cutting edge is 0.015mm to 0.035mm deeply.
As the improvement of technique scheme, the heart of described apex point cutting edge is thick is 0.11mm to 0.135mm.
As the improvement of technique scheme, the limit cutter of described apex point cutting edge is wide is 0.01mm to 0.04mm.
As the improvement of technique scheme, the limit cutter length of described apex point cutting edge is 0.5mm to 0.7mm.
As the improvement of technique scheme, the diameter in described drill lip portion is 0.3mm.
As the improvement of technique scheme, the length of described drill lip portion, connecting portion and body summation is 38mm to 38.3mm.
As the improvement of technique scheme, the diameter of described body is 3.169mm to 3.174mm.
Implement the utility model, there is following beneficial effect: hog nose needle construction of the present utility model is by changing PCB drill point structure, the cross-sectional area of brill core is increased greatly, thus improve the integral rigidity intensity of drill point, not only can make drill point sword extended length, and the rigidity of drill point can also be made also to improve greatly, thus add boring lamination number and the drilling hole amount of boring, reach and enhance productivity, the object reduced costs; The chip chip area of the utility model single-blade drill point can overlength design, and boring pcb board so each time just can increase one deck, and drill point rigidity strengthens greatly simultaneously, and the life-span of drill point increases, the increasing number of boring.

Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, for the structural representation of the hog nose needle construction of the utility model preferred embodiment, hog nose needle construction of the present utility model comprise body 3, with the drill lip portion 1 of described body 3 on same axis and the connecting portion 2 being connected described body 3 and drill lip portion 1, the end in described drill lip portion 1 is provided with apex point cutting edge 11, the outer surface in described drill lip portion 1 is provided with a chip chip area 14, and described chip chip area 14 is extended spirally to connecting portion 2 by the end in drill lip portion 1; Described connecting portion 2 is coniform and included angle A that the is axis of rotation of taper seat and described body 2 is 15 °, and the length of described connecting portion 2 is less than the length of described drill lip portion 1 and body 3.
Wherein, chip chip area 14 mainly plays chip chip removal effect, and the length of chip chip area 14 is 5.5mm to 5.8mm.
As shown in Figure 3, the limit cutter dark 13 of described apex point cutting edge 11 is 0.015mm to 0.035mm; The thick B of the heart of described apex point cutting edge 11 is 0.11mm to 0.135mm.
As shown in Figure 2, the limit cutter wide 12 of described apex point cutting edge 11 is 0.01mm to 0.04mm.
The limit cutter long 15 of described apex point cutting edge 11 is 0.5mm to 0.7mm.
Wherein, the diameter in described drill lip portion is 0.3mm, and the diameter of described body is 3.169mm to 3.174mm, and the length of described drill lip portion, connecting portion and body summation is 38mm to 38.3mm.
As can be seen from the above embodiments, hog nose needle construction of the present utility model is by changing PCB drill point structure, the cross-sectional area of brill core is increased greatly, thus improve the integral rigidity intensity of drill point, not only can make drill point sword extended length, and the rigidity of drill point can also be made also to improve greatly, thus add boring lamination number and the drilling hole amount of boring, reach and enhance productivity, the object reduced costs; The chip chip area 14 of the utility model single-blade drill point can overlength design, and boring pcb board so each time just can increase one deck, and drill point rigidity strengthens greatly simultaneously, and the life-span of drill point increases, the increasing number of boring.
Presented be only a kind of preferred embodiment of the utility model above, certainly can not limit the interest field of the utility model with this, therefore according to the equivalent variations that the utility model claim is done, still belong to the scope that the utility model is contained.
