Description
Technical field
Hole machined instrument is the utility model is related to, a kind of specifically high intensity scrap easily discharges drill bit.
Background technology
Often occur when device to hole is processed since the phenomenon that notch causes bit freezing occurs in bit part cutting edge, sternly
Drill bit can be caused to disconnect in the case of weight, the notch on timely drill edge is smaller to be can continue to carry out hole machined, but right
Often go out less scrap when thicker component is processed and be clipped in cutting portion between the component processed, cause to process
Hole surface out is rough.
The content of the invention
In order to solve above-mentioned purpose the utility model provide one kind can be easy to small scrap discharge, avoid the occurrence of bit freezing and
The rough high intensity scrap of hole surface easily discharges drill bit.
The utility model is achieved through the following technical solutions in order to achieve the above object：
1st, the utility model is that a kind of high intensity scrap easily discharges drill bit, including integrally formed drillstock and drill body,
Cutting slot and cutting portion are provided with drill body, cutting portion side is provided with cutting edge, is set in the opposite side of cutting portion
Gear bits portion is equipped with, chip space is provided with the cutting portion between gear bits portion and cutting edge, drill body upper end is provided with top
Portion's side cutting sword, the lateral cutting edge portion cutting edge in top are connected, and top guide head, top guide head are provided with the top of drill bit
It is connected by the first inclined-plane and the second inclined-plane with both sides at the top of drill body, is all provided with the second inclined-plane of top guide head both sides
It is equipped with cooling hole.
Further improvement of the utility model is：It is provided with drillstock recessed easy to the first groove of clamping and second
Groove.
Further improvement of the utility model is：Bits portion is kept off to the distance of the center line of drill body than cutting edge to brill
The distance of the center line of head body is small.
Further improvement of the utility model is：The 3rd inclined-plane, the 3rd inclined-plane and gear are provided with drill body upper end
Bits portion is connected with the first inclined-plane.
The beneficial effects of the utility model are：Scrap can be discharged out of chip space, avoided small scrap from being produced with hole wall and rubbed
Wiping causes hole wall rough, while can also prevent the phenomenon of bit freezing to a certain extent, gear bits portion can to scrap into
Row is fixed, and the distance of gear bits portion to the center line of drill body is smaller than the distance of the center line of cutting edge to drill body, can
Avoid influencing to continue to drill when small gap occurs in cutting edge, while avoid the occurrence of the situation of Drill Crack, guide head can add
Fast penetration rate.
The utility model is simple in structure, design is reasonable, can continue to practicality in the case where small gap occurs in cutting edge, makes
It is fast with long lifespan penetration rate.
Brief description of the drawings
Fig. 1 is the utility model structure diagram
Wherein：1- drillstocks, 2- drill bodies, 3- cutting slots, 4- cutting portions, 5- gear bits portion, the first inclined-planes of 6-, 7- second are oblique
Face, 8- top guide heads, the 3rd inclined-planes of 9-.
Embodiment
In order to strengthen the understanding to the utility model, the utility model is made below in conjunction with drawings and examples further
Detailed description, the embodiment be only used for explain the utility model, to the scope of protection of the utility model form limit.
As shown in Figure 1, the utility model, which is a kind of high intensity scrap, easily discharges drill bit, including 1 He of integrally formed drillstock
Drill body 2, is provided with cutting slot 3 and cutting portion 4 on drill body 2, and 4 side of cutting portion is provided with cutting edge, is cutting
The opposite side for cutting portion 4 is provided with gear bits portion 5, is provided with chip space on the cutting portion 4 between gear bits portion 5 and cutting edge, is boring
2 upper end of head body is provided with the lateral cutting edge in top, and the lateral cutting edge portion cutting edge in top is connected, and top is provided with the top of drill bit
Portion's guide head 8, top guide first 8 are connected by the first inclined-plane 6 and the second inclined-plane 7 with 2 top both sides of drill body, are led at top
Cooling hole is both provided with to the second inclined-plane 7 of first 8 both sides, the first groove and second easy to clamp is provided with drillstock 1
Groove, easy to fixation, avoids the phenomenon that is had skidded during drilling, gear bits portion 5 to the center line of drill body 2 away from
It is small with a distance from the center line than cutting edge to drill body 2, it can continue to use in the case where small gap occurs in cutting edge,
The less scrap in part is drained in discharge launder during drilling from notch at the same time can avoid small scrap from rubbing with hole wall generation
Wiping causes hole wall rough, and the 3rd inclined-plane 9, the 3rd inclined-plane 9 and gear bits portion 5 and the first inclined-plane 6 are provided with 2 upper end of drill body
It is connected, the 3rd inclined-plane 9 can prevent drill body front end and component contact area is excessive causes penetration rate slow, while also can
Effectively scrap is oriented in cutting slot 3.
The utility model is simple in structure, design is reasonable, can continue to practicality in the case where small gap occurs in cutting edge, makes
It is fast with long lifespan penetration rate.
