Description
Technical field
The utility model relates to a kind of for the blade in high temperature alloy semifinishing, is specifically related to a kind of for the novel indexable grooved turning insert of high temperature alloy semifinishing.
Background technology
High temperature alloy is needs according to aero-jet engine and a kind of metal material grown up, it has high strength, high rigidity, good non-oxidizability, corrosion resistance, good fatigue behaviour, the combination property of fracture toughness, it under the high-temperature oxydation of 600 ~ 1100 DEG C and exhaust gas corrosion condition, can bear complex stress.But high temperature alloy low heat conductivity, inductile, in working angles, cutting force is large, and cutting temperature is high, and work hardening is serious.In the difficulty of machining high temperature alloy, existing blade is mainly manifested in that cutting temperature is high, chip not frangibility, in tool wear is fast, machined surface quality is poor, stock-removing efficiency is low etc.
Summary of the invention
The utility model is solve existing blade serious wear, surface quality is poor, stock-removing efficiency is low problem when cutting high temperature alloy, and then proposes a kind of for the novel indexable grooved turning insert of high temperature alloy semifinishing.
The utility model is the technical scheme taked that solves the problem: the utility model comprises vane body, vane body is square, the middle part of vane body has circular hole, four limits of vane body are provided with main cutting edge, four angles of vane body are provided with Circular Nose Cutting Edge, the rake face of vane body is provided with chip-breaker, and on the rake face of vane body, four right angle are respectively provided with two protruding curved surfaces along main cutting edge length direction.
The beneficial effects of the utility model: the rational grooved of the utility model Curvature varying effectively can change chip-flowing when cutting, and is conducive to the discharge of chip, reduce cutting temperature; Rake face corner of the present utility model place is respectively provided with two protruding curved surfaces, not only effectively strengthen point of a knife intensity, bear certain chip breaking function when different cutting depth and the amount of feeding simultaneously, effectively achieve chip curling, cut and flow out and cut the control fractureed; The cutting edge with chamfered edge increases cutting edge strength, improves cutter life; The cutting edge blunt round radius of change, effectively can reduce cutting temperature and the cutting force of cutting zone, improve tool wear, improves cutter life, improves machined surface roughness, residual stress and case hardness situation simultaneously.The utility model reasonable in design, is easy to realize chip and controls, effectively reduce cutting force, reduce tool wear, improve cutting-tool's used life, improve surface of the work integrality, improve machining efficiency simultaneously.

Fig. 1 is front view of the present utility model.
Fig. 2 be Fig. 1 at A-A section left view.
Fig. 3 be in Fig. 1 B-B to sectional view.
Fig. 4 is that in Fig. 1, C-C is to sectional view, and Fig. 5 is I place enlarged drawing in Fig. 2.
Detailed description of the invention
Detailed description of the invention one: composition graphs 1 to Fig. 4 illustrates present embodiment, described in present embodiment, a kind of novel indexable grooved turning insert of high temperature alloy semifinishing that is used for comprises vane body 1, vane body 1 is square, the middle part of vane body 1 has circular hole 1-1, four limits of vane body 1 are provided with main cutting edge 2, four angles of vane body 1 are provided with Circular Nose Cutting Edge 5, the rake face of vane body 1 is provided with chip-breaker 3, and on the rake face of vane body 1, four right angle are respectively provided with two protruding curved surfaces 4 along main cutting edge 2 length direction.
Detailed description of the invention two: composition graphs 1 and Fig. 2 illustrate present embodiment, a kind of described in present embodiment is straight line sword for high temperature alloy semifinishing with the main cutting edge 2 of novel indexable grooved turning insert, each main cutting edge 2, each Circular Nose Cutting Edge 5 are equipped with chamfered edge 6, the groove width of chip-breaker 3 is change along main cutting edge 2 direction, on rake face, four right angle are respectively provided with two protruding curved surfaces 4 along main cutting edge 2 length direction, also improve point of a knife intensity while that it changes effective chip-breaker width.Design like this is easy to realize chip and flows out, curlingly to control with fractureing, and strengthens cutting edge strength, reduces cutting temperature, raising cutter life.Other composition and annexation identical with detailed description of the invention one.
Detailed description of the invention three: composition graphs 3 and Fig. 4 illustrate present embodiment, a kind of described in present embodiment is 18o for high temperature alloy semifinishing with the positive rake angle of the main cutting edge 2 of novel indexable grooved turning insert, relief angle is 7o, main cutting edge 2 cutting edge blunt round radius (d1) is 30 μm, Circular Nose Cutting Edge 5 mouthfuls of blunt round radius (d2) 20 μm, the arc radius of Circular Nose Cutting Edge 5 is 0.04mm, and the anterior angle of chamfered edge 6 is 7o, and chamfered edge width is 0.05mm.Design like this effectively reduces cutting temperature, cutting force, reduces tool wear and then improves service life of blade, improve surface of the work integrality, improve machining efficiency simultaneously.Other composition and annexation and detailed description of the invention one, two identical.
