Abstract
The utility model discloses a novel drill bit, which comprises a handle and an edge. The outer end of the edge forms a cutting edge, spiral grooves which spirally extend from the cutting edge to the handle are symmetrically arranged on side wall surfaces of the edge, and chip removing channels which spirally extend from the cutting edge to the handle are further symmetrically arranged on the side wall surfaces of the edge and positioned among the spiral grooves. The novel drill bit has the advantages that the novel drill bit is low in abrasion, the service life of the edge of the drill bit is prolonged, chips can be quickly removed from notches, cutting head is reduced, a cutting condition is improved, and cutting progress is accelerated.
Description
Technical field
The utility model relates to a kind of drill bit, in particular, relates to a kind of new drill.
Background technology
As everyone knows, drill bit is in perforate, and friction is the phenomenon that certainly exists, and how to reduce wear is the improvement direction of current drill bit; Existing drill bit generally only is extended with symmetrically arranged helicla flute in apex point to the shank both sides of drill bit end, because of the restriction of structure; When meeting some hard materials, drill bit chip removal resistance increases, and chad is prone between the hole wall of working substance, produce piles up cutting; Increased the wearing and tearing of material to notch simultaneously, caused the drill bit energy consumption high, the life-span is short.Therefore, how to solve the above problems, become problem demanding prompt solution.
The utility model content
The purpose of the utility model is to provide that a kind of cutting resistance is little, chip removal is smooth and easy, can improve working (machining) efficiency and the new drill that increases service life.
A kind of new drill of the utility model; Comprise shank and blade; The outer end of said blade forms cutting blade; Described blade side wall surface is arranged with the helicla flute that is spirally extended to shank by cutting blade, and wherein: the blade side wall surface between helicla flute also is arranged with the channel of chip removal that is spirally extended to shank by cutting blade.
Above-mentioned a kind of new drill, described blade offer cannelure and are communicated with channel of chip removal and helicla flute.
Above-mentioned a kind of new drill, described helicla flute and channel of chip removal parallel spiral and extend, the helical angle that equates with formation between the cutting blade central shaft.
Above-mentioned a kind of new drill, the two ends left and right with it, center, end of said cutting blade are respectively equipped with convexity, constitute mountain font blade.
Above-mentioned a kind of new drill is provided with surface groove between the adjacent convexity, and two surface grooves are respectively positive and negative two sides and are symmetrical set.
After the utility model adopted said structure, when drill bit rotated at a high speed, channel of chip removal had been shared the resistance of chip removal; Chad can be discharged from channel of chip removal and helicla flute smoothly, be difficult between the hole wall of working substance, producing and pile up cutting, reach the purpose of the friction aggravation that prevents between chad and hole wall; Simultaneously also can effectively reduce the bits slag that produces because of frictional resistance is excessive; It is little to have cutting resistance, and chip removal is smooth and easy, can improve boring working (machining) efficiency and the advantage that increases service life.The utility model is specially adapted to bore timber.
Description of drawings
To combine the embodiment in the accompanying drawing that the utility model is done further to specify below, but not constitute any restriction the utility model.
Fig. 1 is the Facad structure sketch map of the utility model;
Fig. 2 is the side structure sketch map of the utility model;
Fig. 3 is the perspective view of the utility model.
Among the figure: shank 1, blade 2, cannelure 21, cutting blade 3, convexity 31, helicla flute 4, channel of chip removal 5.
The specific embodiment
Extremely shown in Figure 3 like Fig. 1; A kind of new drill; A kind of new drill comprises shank 1 and blade 2, and the outer end of blade 2 forms cutting blade 3; Blade 2 side wall surfaces are arranged with the helicla flute 4 that is spirally extended to shank 1 by cutting blade 3, and its blade 2 side wall surfaces between helicla flute 4 also are arranged with the channel of chip removal 5 that is spirally extended to shank 1 by cutting blade 3.
Blade 2 offers cannelure 21 and is communicated with channel of chip removal 5 and helicla flute 4.
Helicla flute 4 parallels spiral with channel of chip removal 5 and extends, the helical angle that equates with formation between cutting blade 3 central shafts.
The two ends left and right with it, center, end of cutting blade 3 are respectively equipped with convexity 31, constitute mountain font blade.
Be provided with surface groove between the adjacent convexity 31, two surface grooves are respectively positive and negative two sides and are symmetrical set.
The utility model installs to bit sets in the drilling attachment in the specific implementation, is holed in the cutting blade 3 alignment work thing surfaces of drill bit blade 2; In boring procedure, chad is discharged outside the hole with channel of chip removal 5 along the helicla flute 4 of drill bit fast, it is little to reach cutting resistance; Chip removal is smooth and easy; Improve working (machining) efficiency and the technique effect that increases service life, when not using, from drilling attachment, separate drill bit to get final product.
The utility model has been processed out actual sample and through repeatedly use test, has been seen that from the effect of use test the utility model can reach the purpose of expection shown in specification and diagramatic content, and practical value is unquestionable.The above embodiment that lifts only is used for conveniently illustrating the utility model; Be not that the utility model is done any pro forma restriction; Have common knowledge the knowledgeable in the technical field under any, if in the scope that does not break away from technical characterictic that the utility model provides, the equivalent embodiment that utilizes technology contents that the utility model discloses to do local change or modified; And do not break away from the technical characterictic content of the utility model, all still belong in the scope of the utility model technical characterictic.
