Description
Technical field
The utility model relates to a kind of five metals machining tool, particularly a kind of carbide alloy shovel drill blade that is applicable to the standard type material.
Background technology
The fluted drill specification of carbide alloy class is all less in the existing market, and big specification adopts the monoblock type cost can very high and difficult processing; And adopt the hard alloy twist drill processed complex of welded type, service life is short.
Summary of the invention
The utility model technical problem to be solved is to overcome existing above-mentioned deficiency in the prior art, and a kind of shovel drill blade that can conveniently load is provided, and can improve drill bit service efficiency and service life, improves machining accuracy.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this shovel drill blade; Comprise fixed position and cutting position, be characterised in that fixed position comprises V-arrangement locating surface, screw hole, the cutting position comprises main cutting edge, web thinning, outer straight sword, land and negative cutting edge; The V-arrangement locating surface cooperates with cutter hub; Be provided with a screw hole in the middle of the shovel drill blade, main cutting edge is the waveform sword and adopts W type apex point that main cutting edge has web thinning; Shovel drill blade cylindrical is provided with land, and shovel drill blade both sides have negative cutting edge.
The axis of the utility model screw hole and blade side vertical line have 5 °～40 ° angle.
The utility model is simple for structure, and conveniently assemble and disassemble improves drill bit service efficiency, service life and machining accuracy.
Description of drawings
Fig. 1 is the front view of the utility model embodiment.
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
Referring to Fig. 1, Fig. 2, present embodiment carbide alloy shovel drill blade comprises fixed position and cutting position, and fixed position comprises V-arrangement locating surface 1, screw hole 2, and the cutting position comprises main cutting edge 3, web thinning 4, outer straight sword 5, land 6 and negative cutting edge 7.
⑴, blade clamping position are the V-arrangement locating surface 1 of suitable angle, and it cooperates with cutter hub and can well be positioned on the cutter hub;
⑵ in the middle of, the shovel drill blade screw hole 2 is arranged, its axis and blade side vertical line have 5 °～40 ° angle;
⑶ the main cutting edge 3 of, shovel drill blade adopts W type apex point, can increase cutter life, reduces axial force and torque
And have a web thinning 4;
⑷, shovel drill blade cylindrical have land 6;
⑸, blade both sides have negative cutting edge 7, increase the intensity of cutting edge;
⑹, main cutting edge 3 adopt the waveform sword, increase the cutting sharpness and the edge strength of cutter;
⑺, anterior angle strengthen, and relief angle strengthens, and cuts sharp.
Because the machine of employing clamping method makes clamping simple, the shovel drill blade can be replaced according to actual needs at any time.
The simple deformation or the combination of every the utility model embodiment technical scheme and technical characterictic all should be thought the protection domain that falls into the utility model.
