Description
Technical field
The utility model relates to the workpiece of cutting implement, be applicable to the duricrust of cutting various woody and herbal stem stalks, nut reality, also be applicable to and carry out high speed and draw, cut, saw, cut processing work such as mill processing the wooden or similar wood materials of various ultrathin types.
Background technology
At present, the duricrust of sawing wood materials and wood (grass) this plant haulm or nut reality mainly adopts traditional carpenter's circular saw bit or the operation of banded saw.Traditional carpenter's circular saw bit flute profile is roomy, tooth pitch is wide, crown is high, land is crossed point, cut that chip removal material piece is big, the anti-strength of cutting is big, to the processing of ultrathin wood materials easily produce broken, otch is chaotic, leave behind the saw and fly stubble, burr, phenomenon such as unsmooth, be unfavorable for ultrathin wood materials and woody and herbal dried, the real shell of nut are carried out retrofit.Side set metal saw, carbide alloy side set metal saw, the common metal saw of metal processing usefulness, its flute profile is roomy, tooth pitch is long, the number of teeth is few, crown is high, chisel edge is wide, chip pocket is dark, smear metal becomes web-like, though the processing intensity of side set design can raising point of a knife, help metal is carried out big cutting data processing, raising is to the production efficiency of metal processing, but owing to there are the problems referred to above, also be unfavorable for ultra-thin wood materials and woody and herbal dried, the real shell of nut are carried out retrofit.
Summary of the invention
The purpose of this utility model is a kind of wedge shape serration type cutting knife of design, is used for the machining to the duricrust of various woody and herbal stem stalks, nut reality.
Comprise that in order to reach the technical scheme that the purpose of this utility model takes its center can hard-wired rosette, be evenly equipped with the wedge shape sawtooth in the outer rim of this disk, the cross section of wedge shape sawtooth is wedge shape, and crossing at cutting knife outer rim place is an angle of wedge c;
In the above-mentioned wedge shape serration type cutting knife, have the groove for cuttings 6 of annular on the card of described disk, the outer rim of this groove for cuttings 6 is positioned at the waist of wedge shape sawtooth;
In the above-mentioned wedge shape serration type cutting knife, the wedge shape sawtooth is by positive cutting blade 2, top sword 3, back of the body sword 4 and chip pocket transition arc 5 constitute, top sword 3 links to each other with back of the body sword 4 tops with positive cutting blade 2 in the outer rim of cutting knife, back of the body sword 4 is connected by chip pocket transition arc 5 with the positive cutting blade of next tooth, positive cutting blade 2 and crown to the line of the cutting knife centre of gyration angle a that recedes, back of the body sword 4 and just cutting blade 2 be an angle b;
In the above-mentioned wedge shape serration type cutting knife, the recess of groove for cuttings 6 is camber line shape;
In the above-mentioned wedge shape serration type cutting knife, described groove for cuttings 6 is symmetrical arranged at the positive and negative of disk.
The utility model is because sawtooth is wedge shape, and when rapidoprint, it is narrow compared with prior art to have a joint-cutting, otch is even, cut edge no broken stubble, noresidue burr, smooth, the not burnt edge of cutting edge, the chip removal smoothness is not destroyed the overall structure of rapidoprint, advantages such as operating efficiency height.This new-type cutter can be installed in various saws, mill on machinery and the special-purpose machinery, has a extensive future.
