Abstract
The utility model discloses a smart cutting blade cutter, including blade and cutter arbor, the clamp plate fastens the blade on the cutter arbor, and the blade includes the tool bit, and the knife tip sword department of tool bit is equipped with the knife tip circular arc, and the both sides of knife tip circular arc are equipped with the cutting edge, and the tangent line of knife tip circular arc and cutting edge straight line portion is equipped with smart cutting blade. The utility model discloses to the multiplication of cutting process efficiency, shorten process time greatly, promptly: amount of feeding multiplication, and do not reduce the machined surface roughness. Two unifications of semifinishing and finish machining are raised the efficiency, compare with the circular arc cutting edge, use smart cutting blade can obtain better machined surface roughness.
Description
Technical field
The utility model relates to a kind of metal cutting process cutter, particularly relates to a kind of smart cutting blade cutter, for semifinishing and fine finishining.
Background technology
Milling machine is a kind of broad-spectrum lathe, on milling machine can processing plane (horizontal plane, vertical plane), groove (keyway, T-slot, dovetail groove etc.), point tooth part (gear, splined shaft, sprocket wheel), helical surface (screw thread, helicla flute) and various curved surface.In addition, also can be used for revolving body surface, interior hole machined and carry out cut-out work etc.Operationally, workpiece dress on the table or on the first-class annex of calibration, milling cutter rotates to be main motion, and be aided with the feed motion of workbench or milling head, workpiece can obtain required finished surface for milling machine.Owing to being multiple-cutting-edge interrupted cut, thus the productivity ratio of milling machine is higher.In simple terms, milling machine can carry out the lathe of milling, drilling and Boring to workpiece.Raising along with modern's aesthetic conceptions and the requirement to texture improve, surface roughness becomes one of problem that client is concerned about most, reduce the amount of feeding or increase nose radius all can reduce surface roughness value, but the former can reduce production efficiency, and the latter can make cutting force increase.Wiper insert is exactly the highly-efficient processing blade developed based on this thought.Its fundamental design idea is the geometry adjusting point of a knife in the maximum permission nose radius margin of tolerance of standard insert, makes it be similar to elliptical shape.CN203843200U is with the carbide-tipped lathe tool sheet of wiper edges, comprise main cutting edge and front cutting edge, tool arc is had between main cutting edge and front cutting edge, wiper edges is provided with between tool arc and front cutting edge, the angle of wiper edges and main cutting edge is greater than the angle of front cutting edge and main cutting edge, wiper edges is linear blade, and described wiper edges is perpendicular to main cutting edge.Its cutting effect is pretty good, but its complex structure, cost of manufacture is high.
Summary of the invention
The purpose of this utility model is not to provide a kind of smart cutting blade cutter, high with the suface processing quality overcoming workpiece in prior art, surface roughness is high and the not high problem of efficiency, overcomes the complex structure of prior art, the problem that cost of manufacture is high simultaneously.
In order to solve the problem, the technical solution adopted in the utility model is:
The utility model provides a kind of smart cutting blade cutter, and comprise blade and knife bar, blade is fastened on knife bar by pressing plate, blade comprises cutter head, the point of a knife sword place of cutter head is provided with tool arc, and the both sides of tool arc are provided with cutting edge, and the tangent line of tool arc and cutting edge line part is provided with smart cutting blade.
Further, the radius r of described tool arc is 0.80mm ~ 1.20mm.
Further, described smart cutting blade, width is 0.30mm ~ 0.45mm, and height H is 0.02mm ~ 0.04mm.
The beneficial effects of the utility model:
1, the utility model improves the design of smart cutting blade, to the multiplication of machining efficiency, greatly shortens process time, that is: amount of feeding multiplication, and does not reduce machined surface roughness.Semifinishing and fine finishining two-in-one, raise the efficiency, compared with arc edge, use smart cutting blade can obtain better machined surface roughness.
2, the radius r of the utility model tool arc is 0.80mm ~ 1.20mm, this circular arc plays a role to cutting edge rounding polishing, thus improve impact resistance, the raising wearability of cutting edge, extend the service life of cutter (blade).
3, the utility model sets smart cutting blade width at the tangent line of tool arc and cutting edge line part is 0.30mm ~ 0.45mm, and height H is 0.02mm ~ 0.04mm.Make semifinishing and fine finishining two-in-one, raise the efficiency, compared with simple arc edge, use smart cutting blade (wiper edges) that better machined surface roughness can be obtained.
Accompanying drawing illustrates:
Fig. 1 is front view of the present utility model;
Fig. 2 is cutter head partial enlarged drawing one of the present utility model;
Fig. 3 is cutter head partial enlarged drawing two of the present utility model.
Detailed description of the invention
Specifically set forth the utility model below in conjunction with embodiment, but do not limit its content.
Embodiment
See Fig. 1, a kind of smart cutting blade cutter comprises blade 3 and knife bar 1, and blade 3 is fastened on knife bar 1 by pressing plate 2, and pressing plate 2 is fixed on knife bar 1 by screw 4.
See Fig. 2, blade 3 comprises cutter head 6, and the point of a knife sword place of cutter head 6 is provided with tool arc 7, and the both sides of tool arc 7 are provided with cutting edge 8, and the tangent line of tool arc 7 and cutting edge 8 line part is provided with smart cutting blade 5.
See Fig. 3, the radius r of described tool arc 7 is 0.80mm ~ 1.20mm.Described smart cutting blade 5, width is 0.30mm ~ 0.45mm, and height H is 0.02mm ~ 0.04mm.
Table 1 be without smart cutting blade and have smart cutting blade cutter processing after the parameter comparison of surface roughness and surface roughness schematic diagram: Ra profile arithmetic average error: in sample length, the arithmetic mean of instantaneous value of profile offset distance absolute value; Rz nao-and micro relief 10 height: the mean value of profile peak height maximum in sample length and the dark mean value sum of five maximum profile paddy.
Table 1
Table 2 is the tool sharpening surface roughness test report (material hardness HRC58-62) having smart cutting blade.
