Abstract
The utility model relates to a shoveling and drilling blade, comprising a fixing part and a cutting part. The shoveling and drilling blade is characterized in that the fixing part comprises a V-shaped positioning surface and a screw hole; the cutting part comprises a main cutting edge, a transverse coping edge, an outer straight edge, an edge belt and secondary cutting edges; the V-shaped positioning surface is matched with a cutter body; the screw hole is formed in the middle of the blade; the main cutting edge is a wave-shaped edge and adopts a W-shaped coping drill point; the main cutting edge is provided with the transverse coping edge; an edge belt is arranged on the outer circle of the blade; and the secondary cutting edges are arranged at both sides of the blade. According to the shoveling and drilling blade disclosed by the utility model, an included angle between an axis of the screw hole and a vertical line of the side surface of the blade is 5-40 degrees. The shoveling and drilling blade disclosed by the utility model has the advantages of concise structure and convenience in dismounting. The use efficiency, the service life and the machining precision of a drill can be improved.
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 processing soft 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 reconditioning 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 reconditioning apex point, can increase cutter life, reduces axial force and torque and has web thinning 4;
⑷, shovel drill blade cylindrical have land 6;
⑸, shovel drill 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.
