Description
Technical field
The present invention relates to hole machined instrument, specifically a kind of high intensity scrap easily discharges drill bit.
Background technology
Often occur when device to hole is processed because the phenomenon that breach causes bit freezing occurs in bit part cutting edge, sternly
Drill bit can be caused to disconnect in the case of weight, the breach on timely drill edge is smaller to be can continue to carry out hole machined, but right
Often go out less scrap when thicker part is processed and be clipped in cutting portion between the part processed, cause to process
Hole surface out is rough.
The content of the invention
It can be easy to small scrap discharge the invention provides one kind to solve above-mentioned purpose, avoid the occurrence of bit freezing and hole table
The rough high intensity scrap in face easily discharges drill bit.
The present invention is achieved through the following technical solutions in order to achieve the above object：
1st, the present invention is that a kind of high intensity scrap easily discharges drill bit, including integrally formed drillstock and drill body, in drill bit sheet
Cutting slot and cutting portion are provided with body, cutting portion side is provided with cutting edge, the opposite side of cutting portion is provided with gear bits
Portion, chip area is provided with the cutting portion kept off between bits portion and cutting edge, top side cut is provided with drill body upper end
Sword is cut, the lateral cutting edge portion cutting edge in top is connected, and top guide head, top guide head and drill bit sheet are provided with the top of drill bit
Both sides are connected by the first inclined-plane and the second inclined-plane at the top of body, and cooling is provided with the second inclined-plane of top guide head both sides
Hole.
Further improvement of the present invention is：The first groove and the second groove for being easy to clamp are provided with drillstock.
Further improvement of the present invention is：Bits portion is kept off to the distance of the center line of drill body than cutting edge to drill bit sheet
The distance of the center line of body is small.
Further improvement of the present invention is：The 3rd inclined-plane, the 3rd inclined-plane and gear bits portion are provided with drill body upper end
It is connected with the first inclined-plane.
The beneficial effects of the invention are as follows：Scrap can discharge out of chip area, avoid small scrap from producing friction with hole wall and lead
Pore wall is rough, while can also prevent the phenomenon of bit freezing to a certain extent, and gear bits portion can consolidate to scrap
Fixed, 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
Influence to continue to drill when small gap occurs in cutting edge, while avoid the occurrence of the situation of Drill Crack, guide head can be accelerated to bore
Hole speed.
The present invention is simple in construction, reasonable in design, can continue to practicality in the case where small gap occurs in cutting edge, uses the longevity
It is fast to order long drilled holes speed.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention
Wherein：1- drillstocks, 2- drill bodies, 3- cutting slots, 4- cutting portions, 5- gear bits portion, the inclined-planes of 6- first, the inclined-planes of 7- second,
8- top guide heads, the inclined-planes of 9- the 3rd.
Embodiment
In order to strengthen the understanding of the present invention, present invention work is further retouched in detail below in conjunction with drawings and examples
State, the embodiment is only used for explaining the present invention, and protection scope of the present invention is not formed and limited.
As shown in figure 1, the present invention, which is a kind of high intensity scrap, easily discharges drill bit, including integrally formed drillstock 1 and drill bit
Body 2, cutting slot 3 and cutting portion 4 are provided with drill body 2, the side of cutting portion 4 are provided with cutting edge, in cutting portion 4
Opposite side be provided with gear bits portion 5, chip area is provided with the cutting portion 4 between gear bits portion 5 and cutting edge, in drill body
2 upper ends are provided with the lateral cutting edge in top, and the lateral cutting edge portion cutting edge in top is connected, and top guide is provided with the top of drill bit
First 8, top guide first 8 is connected with the top both sides of drill body 2 by the first inclined-plane 6 and the second inclined-plane 7, in top guide first 8
Cooling Holes are provided with second inclined-plane 7 of both sides, the first groove and the second groove for being easy to clamp are provided with drillstock 1,
It is easy to fix, avoids occurring the phenomenon skidded during drilling, the distance ratio in gear bits portion 5 to the center line of drill body 2
The distance of cutting edge to the center line of drill body 2 is small, can continue to use in the case where small gap occurs in cutting edge, simultaneously
The less scrap in part is drained in discharge launder during drilling from breach can avoid small scrap from being led with hole wall generation friction
Pore wall is rough, and the 3rd inclined-plane 9, the 3rd inclined-plane 9 and gear bits portion 5 and the phase of the first inclined-plane 6 are provided with the upper end of drill body 2
Even, the 3rd inclined-plane 9 can prevent drill body front end and component contact area is excessive causes penetration rate slow, while can also have
Scrap is oriented in cutting slot 3 by effect.
The present invention is simple in construction, reasonable in design, can continue to practicality in the case where small gap occurs in cutting edge, uses the longevity
It is fast to order long drilled holes speed.
