Reason, a kind of PA drill bit easy to use, aperture impulse- free robustness improve aperture quality and aperture efficiency.
In order to achieve the above purposes, the technical solution adopted by the utility model is:, and it includes bit matrix；The drill bit base
Body is made of shank, transition cone and bit head；Transition is equipped on the downside of shank to bore；Transition cone downside is equipped with bit head；Shank, transition
Cone and bit head are an integral molding structure；The bit head is made of the body of rod, wing body and edge；Transition cone downside is equipped with bar
Body；The wing body of helicoidal structure is equipped on the downside of the body of rod；The outer edge of wing body is equipped with edge；The body of rod, wing body and edge are
Integral structure.
Further, the length of the bit matrix is 38mm-55mm；
Further, the bit matrix is carbide drill matrix.
Further, the shank upper end is fixed with connector；Shank and connector are an integral structure.
Further, the outer diameter taper of the edge is 0.0025/1-0.0033/1.
Further, the outer surface of the wing body is located on the same cylindrical surface, the diameter on cylindrical surface and the body of rod it is straight
Diameter is equal.
After adopting the above structure, the utility model has the beneficial effect that a kind of PA drill bit described in the utility model, aperture without
Burr improves aperture quality and aperture efficiency, and practicability is stronger, and the utility model has structure simple, and setting rationally, is fabricated to
This low advantage.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property
It puts, is also possible to obtain other drawings based on these drawings.
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the portion A amplification assumption diagram in Fig. 1.
Description of symbols:
3, bit head 4, body of rod 4-1, wing body 4-2, edge 4-3, connector 5 are bored in bit matrix 1, shank 2, transition.
Specific embodiment
The utility model will be further described below with reference to the accompanying drawings.
Referring to as shown in Figure 1 to Figure 2, present embodiment the technical solution adopted is that: it includes bit matrix 1；Institute
The bit matrix 1 stated is made of shank 2, transition cone 3 and bit head 4；The diameter of shank 2 is 4mm；Transition is equipped on the downside of shank 2
Cone 3；3 downside of transition cone is equipped with bit head 4；The length of bit head 4 is 7mm；Shank 2, transition cone 3 and bit head 4 are integrated into
Type structure；Bit head 4 is formed by semi-automatic grinder reconditioning；The bit head 4 is by body of rod 4-1, wing body 4-2 and edge
4-3 is constituted；3 downside of transition cone is equipped with body of rod 4-1；The wing body 4-2 of helicoidal structure is equipped on the downside of body of rod 4-1；The length of wing body 4-2
Degree is 6mm；The outer edge of wing body 4-2 is equipped with edge 4-3；Body of rod 4-1, wing body 4-2 and edge 4-3 are integral type knot
Structure.
Further, the length of the bit matrix 1 is 50mm；It can also according to the actual situation, by the length of bit matrix
Degree is made as 38mm, 45mm or 55mm；
Further, the bit matrix 1 is carbide drill matrix.
Further, 2 upper end of shank is fixed with connector 5；The left side diameter of connector 5 is straight with shank 2
Diameter is identical；The left side diameter of connector 5 is greater than the right side diameter of connector 5；Shank 2 and connector 5 are an integral structure.
Further, the outer diameter taper of the edge 4-3 is 0.0025/1-0.0033/1.
Further, the outer surface of the wing body 4-2 is located on the same cylindrical surface, the diameter and body of rod 4- on cylindrical surface
1 diameter is equal；The diameter of body of rod 4-1 is 1.3mm.
The principle of present embodiment: the length of bit matrix 1 is 50mm, and the length of wing body 4-2 is 6mm；Pass through half
Autogenous mill reconditioning, the manufacturing time is shorter, reduces labour cost and time cost, effectively save cost；Edge
