Technical field

The utility model relates to a kind of cutter, particularly relates to a kind of engraving cutter.

Background technology

Engraving is more and more subject to the favor of consumers in general now, and especially woodcarving is particularly welcome.In woodcarving patterns, avian species is the favorite patterns of sculpture art men, existing avian species carving is all comparatively intactly embody bird attitude in macroscopic view mostly, but on microcosmic, cannot the minutias such as the expression of bird, feather be accomplished ultimate attainment, especially when processing the round dot of depiction, existing engraving cutter, cannot the smooth mellow and full round dot pattern of carve tangent plane due to structural restriction.

Utility model content

Technical problem to be solved in the utility model is, for solving because tradition scrapes knife milling tool cannot carry out careful engraving problem to the round dot pattern in avian species depiction.

For solving the problems of the technologies described above, the utility model provides following technical scheme:

A kind of engraving cutter, for carving round dot on material for carving on it.Engraving cutter comprises knife bar and cutter head, and cutter head is connected to one end of knife bar.Cutter head comprises rake face, rear knife face, minor flank and side knife surface, and rake face is relative with minor flank, and rear knife face is relative with side knife surface.Rake face is crossing with rear knife face forms major cutting edge, rake face formation first crossing with side knife surface auxiliary-blade, rear knife face formation second crossing with minor flank auxiliary-blade, side knife surface formation three crossing with minor flank auxiliary-blade.Major cutting edge, the first auxiliary-blade, the second auxiliary-blade and the 3rd auxiliary-blade cross to some formation point of a knife.

Wherein, point of a knife is positioned in the axle of knife bar.

Wherein, cutter head is cone.

Wherein, the angle between major cutting edge and the first auxiliary-blade is θ 1, and the angle between the second auxiliary-blade and the 3rd auxiliary-blade is θ 2, angle between major cutting edge and the second auxiliary-blade is θ 3, angle between first auxiliary-blade and the 3rd auxiliary-blade is that θ 4, θ 1 equals θ 2, θ 3 and equals θ 4.

Wherein, θ 1 equals 20 °.

Wherein, the cross section of cutter head is parallelogram.

Wherein, the angle between rake face and rear knife face is 82 °.

When the engraving cutter adopting the utility model to provide is carved the round dot pattern in depiction, utilize the design of major cutting edge, the first auxiliary-blade, the second auxiliary-blade and the 3rd auxiliary-blade, make major cutting edge after cutting pattern, successively cutting finished surface is polished again through the first auxiliary-blade, the second auxiliary-blade and the 3rd auxiliary-blade, effective removal burr etc., make the surface of round dot pattern more smooth mellow and full and structure is careful, reach and pursue realistic effect, risen to higher artistic level.

Detailed description of the invention

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.

As shown in Figure 1, the utility model provides a kind of engraving cutter 100, for carving round dot on material for carving on it, makes round dot pattern more fine and smooth exquisite.This engraving cutter 100 comprises cutter head 10 and knife bar 20, and cutter head 10 is connected to one end of knife bar 20, and in the present embodiment, cutter head 10 is integrated with knife bar 20 is real.During use, knife bar 20 is installed on gas mill pen, rotates with pneumatic drive engraving cutter 100 and get ready.In the present embodiment, knife bar 20 is cylinder.In other embodiments, the demand that knife bar 20 can grind pen according to gas is made into the shape coordinated with it, and such as, knife bar 20 can be prism etc.

Simultaneously with reference to Fig. 2 and Fig. 3, cutter head 10 comprises rake face 110, rear knife face 120, minor flank 130 and side knife surface 140, and rake face 110, rear knife face 120, minor flank 130 and side knife surface 140 all extend to the direction away from knife bar 20 and cross to some formation taper.Rake face 110 is relative with minor flank 130, rear knife face 120 is relative with side knife surface 140, rake face 110 is crossing with rear knife face 120 forms major cutting edge 150, rake face 110 formation first crossing with side knife surface 140 auxiliary-blade 160, rear knife face 120 formation second crossing with minor flank 130 auxiliary-blade 170, side knife surface 140 formation three crossing with minor flank 130 auxiliary-blade 180, major cutting edge 150, first auxiliary-blade 160, second auxiliary-blade 170 and the 3rd auxiliary-blade 180 cross to some formation point of a knife 190.In the present embodiment, point of a knife 190 is positioned on the central shaft C of knife bar 20.Angle between major cutting edge 150 and the first auxiliary-blade 160 is θ 1, angle between second auxiliary-blade 170 and the 3rd auxiliary-blade 180 is θ 2, angle between major cutting edge 150 and the second auxiliary-blade 170 is θ 3, angle between first auxiliary-blade 160 and the 3rd auxiliary-blade 180 is θ 4, in the present embodiment, angle theta 1 equals angle theta 2, angle theta 3 equals angle theta 4, and the number of degrees of angle theta 1 are greater than the number of degrees of angle theta 3, this makes the rake face 110 of cutter head 10 comparatively flat with minor flank 130, when carving, make the delivery ratio of chip more smooth, wood chip effectively can be avoided to extrude cutting edge and reduce the loss of cutter, ensure that the stability of engraving, thus prevent from wandering off when carving round dot.In other embodiments, angle theta 1, θ 2, θ 3 and θ 4 can be unsuitable mutually, can need to make the number of degrees between specific angle equal according to engraving yet.In the present embodiment, the angle theta 1 between major cutting edge 150 and the first auxiliary-blade 160 equals 20 °.As shown in Figure 4 and Figure 5, in the present embodiment, the cross section of cutter head 10 is parallelogram, and the angle between rake face 110 and rear knife face 120 is acute angle, improves sharpness and the intensity of main cutting edge, add the smoothness of the patterned surfaces carved, in the present embodiment, the angle theta 5 between rake face 110 and rear knife face 120 is 82 °, in other embodiments, according to the hardness of material for carving on it or the demand of depiction, the number of degrees of suitable increase or reduction θ 5.In other embodiments, the cross section of cutter head 10 can be rectangle, other quadrangles such as trapezoidal.

In the present embodiment, the length L1 of engraving cutter 100 is 35 millimeters, and the length L2 of cutter head 10 is 12 millimeters, and the diameter R of knife bar 20 is 3 millimeters.In the present embodiment, the material of carving tool selection is spring steel or tool steel.

When round dot pattern in the engraving cutter 100 pairs of depictions adopting the utility model to provide is carved, utilize the design of major cutting edge 150, first auxiliary-blade 160, second auxiliary-blade and the 3rd auxiliary-blade, make major cutting edge 150 after cutting pattern, successively cutting finished surface is polished again through the first auxiliary-blade 160, second auxiliary-blade and the 3rd auxiliary-blade, effective removal burr etc., make the surface of round dot pattern more smooth mellow and full and structure is careful, reach and pursue realistic effect, risen to higher artistic level.

The above is preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
