Abstract
The utility model relates to an improved planar multi-point-angle drill bit. The improved planar multi-point-angle drill bit comprises a bit body, a drill stock and a base, wherein the bit body comprises a drill point and cutting edges, chip grooves are formed among the cutting edges, the drill stock is connected at the lower part of the bit body and is connected with the base, and chip removal fans are respectively arranged at two sides of the base. Through the improvement, the improved planar multi-point-angle drill bit has the characteristics of being complete in removing chips, convenient to operate, good in safety, and convenient to maintain and care.
Description
Technical field
The utility model relates to a kind of drill bit, relates in particular to a kind of improved plane many sharp angles drill bit.
Background technology
In industrial production processing, often can use drill bit, many sharp angles of plane drill bit especially, this drill bit is equal to or slightly greater than the Structure Method anterior angle of the common fluted drill outer rim turning point before reconditioning by the Structure Method anterior angle ground, and remains on whole cutting edge constant.Main cutting edge does not become, chisel edge retains former length, to reduce axial force and moment of torsion, thereby increase the impulsive force of drill bit, yet, in the use of plane many sharp angles drill bit, due to the impulsive force that has increased drill bit, cause chip to flash, and long-time use does not add the nursing chip can block chip area, thereby the problem that causes wearing and tearing and reduce service life to drill bit.
The utility model content
The problem that the utility model exists for prior art, provide improved plane many sharp angles drill bit that a kind of anti-dandruff thorough, easy to use, safe property is good and be convenient to cleaning.
A kind of technical scheme that the utility model provides is: a kind of improved plane many sharp angles drill bit, comprise drill bit, drillstock and base, described drill bit comprises apex point and cutting edge, be provided with chip area between described cutting edge, described drill bit bottom connects described drillstock, and described drillstock connects described base, respectively is provided with the anti-dandruff fan that the chip in chip area is drained on described base two ends,, described anti-dandruff fan is provided with switch.
Further improvement of the utility model is: described each anti-dandruff fan front end is provided with filter screen.
Further improvement of the utility model is: described base is provided with groove, in described groove, is placed with dust removal brush.
Further improvement of the utility model is: described susceptor surface scribbles insulating barrier.
The beneficial effects of the utility model are: 1. anti-dandruff thorough.2. easy to operate.3. security is good.4. be convenient to maintenance and nursing.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model
1-drill bit, 2-drillstock, 3-base, 4-apex point, 5-cutting edge, 6-chip area, 7-anti-dandruff fan, 8-filter screen, 9-groove, 10-dust removal brush, 11-insulating barrier, 12-switch.
The specific embodiment
In order to deepen understanding of the present utility model, below in conjunction with embodiment, the utility model is described in further detail, and this embodiment only, for explaining the utility model, does not form the restriction to the utility model protection domain.
The present embodiment is as shown in Figure 1: a kind of improved plane many sharp angles drill bit, comprise drill bit 1, drillstock 2 and base 3, described drill bit 1 comprises apex point 4 and cutting edge 5, be provided with chip area 6 between described cutting edge 5, described drill bit 1 bottom connects described drillstock 2, described drillstock 2 connects described base 3, and described base respectively is provided with the anti-dandruff fan 7 that the chip in chip area 6 is drained on 3 two ends, and described anti-dandruff fan 7 is provided with switch 12.
The utility model is when concrete the use, because plane many sharp angles drill bit impact power is larger, when operation, material can splash everywhere, and major part can be wrapped on chip area 6, accumulate over a long period and not only can block chip area 6 and also can cause wearing and tearing to corrode to cutting edge 5, thereby reduce the service life of drill bit 1, described base 3 both sides respectively are provided with anti-dandruff fan 7, wind-force by anti-dandruff fan 7 is drained the chip of material from chip area 6, reduced greatly the obstruction of material chip to drill bit 1, described anti-dandruff fan 7 front ends are provided with filter screen 8, can prevent chip, dust blocks anti-dandruff fan 7, after using end, because described base 3 is provided with groove 9, be placed with dust removal brush 10 in described groove 9, can remove chip and dust remaining on drill bit 1 by dust removal brush 10, thereby reach the purpose increased the service life, dust removal brush 10 can leave in groove 9, easy to carry, and described base 3 surfaces scribble insulating barrier 11, can prevent that drill bit 1 from electric leakage occurring and wait contingency.
