Technical field
The utility model belongs to cutting element field, more particularly, to a kind of multiple-cutting-edge drill bit.
Background technology
With the development of printed circuit board (PCB) technology and product, the miniature multiple-cutting-edge for being used to process printed circuit board is bored
The requirement of head is also higher and higher.PCB is a kind of complex-shaped with the micro- of helicla flute with miniature multiple-cutting-edge drill bit (the micro- brills of abbreviation PCB)
Hole machined instrument is derived by traditional fluted drill.The micro- brill sizes of PCB are small, and apex point structure will be by light microscope
Just it is observed that.Current major part PCB producers carry out processing PCB using numerical control drilling machine, and digital control hole drilling is the important of printed board processing procedure
Link, since the material of PCB is different from metal, so the processing of PCB is also different from traditional intermetallic composite coating, PCB by resin and
The materials such as copper-clad plate are made, the chip space discharge being not easy in High-speed machining by brill body of such material, therefore the micro- brills of PCB
Chip removal performance and hold bits performance be directly related to the thick performance in hole of multiple-cutting-edge drill bit and lose performance.
Utility model content
The purpose of this utility model is to provide a kind of multiple-cutting-edge drill bit, can effective chip removal, it is good to hold bits performance, drill bit
Service life is long.
To achieve the above object, the utility model uses following technical scheme：
A kind of multiple-cutting-edge drill bit, including sequentially connected apex point end, a chip removal end and secondary chip removal end, the apex point end bag
The drill headstock of tool conical side is included, the busbar of cutter groove along conical side is distributed in the drill headstock, and blade is arranged at described
Cutter groove.
Preferably, the blade includes the flat tooth blade of spaced setting and pointed tooth blade.
Preferably, a chip removal end includes at least two debris guide grooves and is oriented to spiral blade, the chip removal
Guide groove extends to the secondary chip removal end from the apex point end, and groove width gradually increases, described in the guiding spiral blade connection
Blade.
Preferably, the quantity of the blade is identical with the quantity of the guiding spiral blade.
Preferably, the secondary chip removal end includes stomata, and the stomata includes mutual perforative inlet end and outlet side, institute
It states outlet side and is located at the secondary chip removal end wall, the inlet end connects air supply plant.
After adopting the above technical scheme, the utility model compared with background technology, has the following advantages that：
First, multiple-cutting-edge drill bit described in the utility model is divided into three sections, when the brill tip falls, only need to scrap the brill
Tip, other sections may be reused, and save consumptive material.
2nd, multiple-cutting-edge drill bit described in the utility model includes two chip removal ends, and one time chip removal end is led by the debris
Slot carries out nature chip removal, and groove width is sequentially increased so that chip removal performance and appearance bits performance enhancement；The secondary chip removal end cooperation is supplied gas
Device, the gas blown out from the outlet side blow out chip, increase appearance bits chip removal performance, effectively increase multiple-cutting-edge drill bit
The thick performance in hole and performance is lost, extend the service life of multiple-cutting-edge drill bit.
3rd, the flat tooth blade and the alternate setting of the pointed tooth blade, the separation chip that blade interlocks, the area of cut is small,
Cut it is brisk, be conducive to improve cutting speed, improve work efficiency, reduce power consumption, while using multiple-cutting-edge can also improve cutting stablize
Property.
4th, the apex point end includes the drill headstock of tool conical side, and the busbar of cutter groove along conical side is distributed in institute
Drill headstock is stated, blade is arranged at the cutter groove, since the axially distributed blade radical length in conical side shortens, by
Power area reduces, and makes blade forced area uniform, reduces the abrasion of blade, extend blade service life, so as to extend
The service life at the apex point end.
Description of the drawings
Fig. 1 is a kind of structure diagram of drill bit provided by the utility model；
Fig. 2 is a kind of secondary chip removal end cut-away view of drill bit shown in FIG. 1.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, is further elaborated the utility model.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
Embodiment
It please refers to Fig.1 and Fig. 2, the utility model discloses a kind of multiple-cutting-edge drill bit, including sequentially connected apex point end, once
Chip removal end 12 and secondary chip removal end 13.
Apex point end includes the drill headstock 14 of tool conical side, and cutter groove is distributed in drill headstock along the busbar of conical side
14, blade is arranged at cutter groove.Blade includes the flat tooth blade 15 of spaced setting and pointed tooth blade 16.
Chip removal end 12 includes at least two debris guide grooves 11 and is oriented to spiral blade 17, and chip removal guide groove 11 is from brill
Tip extends to secondary chip removal end 13, and groove width gradually increases, and is oriented to spiral blade 17 and connects blade.The quantity and guiding of blade
The quantity of spiral blade 17 is identical.
Secondary chip removal end 13 includes stomata, and stomata includes mutual perforative inlet end 131 and outlet side 133, outlet side 133
Positioned at secondary 13 side wall of chip removal end, inlet end 131 connects air supply plant.
After adopting the above technical scheme, the utility model compared with background technology, has the following advantages that：
First, the multiple-cutting-edge drill bit of the utility model is divided into three sections, when boring tip falls, only need to scrap apex point end, other sections
Position may be reused, and save consumptive material.
2nd, the multiple-cutting-edge drill bit of the utility model include two chip removal ends, a chip removal end 12 by debris guide groove 11 into
Row nature chip removal, groove width is sequentially increased so that chip removal performance and appearance bits performance enhancement；Secondary chip removal end 13 coordinates air supply plant, from
The gas that outlet side 133 is blown out blows out chip, increases appearance bits chip removal performance, effectively increases the thick performance in hole of multiple-cutting-edge drill bit
And performance is lost, extend the service life of multiple-cutting-edge drill bit.
3rd, 16 alternate setting of flat tooth blade 15 and pointed tooth blade, the separation chip that blade interlocks, the area of cut is small, cutting
It is brisk, be conducive to improve cutting speed, improve work efficiency, reduce power consumption, while cutting stability can also be improved using multiple-cutting-edge.
4th, apex point end includes the drill headstock 14 of tool conical side, and cutter groove is distributed in drill bit along the busbar of conical side
