Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of index lathe paring blade of simplified chip-breaker, slots Type simple shape, demoulding convenience when being molded blank, and base blank will not be damaged, for a long time using powder will not be glued in rear mold, both It will not influence blade appearance, and reduce the cleaning time of mold.
The utility model is to solve above-mentioned technical problem by following technical proposals: a kind of simplified chip-breaker turns Position turning insert, which is characterized in that it includes cutter hub, chip-breaker, supporting surface, identified surface, rake face, flank, circular hole, circular arc Sword, transitional edges, main cutting edge, chamfered edge, cutter hub are diamond shape, and the center of cutter hub is equipped with circular hole, and four sides of cutter hub are equipped with Main cutting edge, the upper surface of cutter hub are surrounded by rake face, and four surfaces all around of cutter hub are equipped with flank, cutter hub Upper face center is equipped with supporting surface, and supporting surface center is equipped with identified surface, and each rake face is equipped with chip-breaker, each knife of cutter hub Point is equipped with Circular Nose Cutting Edge and transitional edges, and Circular Nose Cutting Edge is connected by transitional edges with main cutting edge, Circular Nose Cutting Edge, transitional edges and main cutting edge It is equipped with chamfered edge, in which:
Chip-breaker includes chip breaking sword, crestal surface, joint face, and chip breaking sword is connected by joint face with crestal surface.
Preferably, screw thread is equipped in the circular hole.
Preferably, the chip breaking sword is all made of the shape of similar wave with rake face.
Preferably, the chip-breaker uses arcuate structure.
Preferably, the identified surface is using internal recessed planar structure.
The positive effect of the utility model is: the utility model chip-breaker simple shape is readily produced, molding Convenience is demoulded when blank, and will not damage base blank, for a long time using that will not glue powder in rear mold, both will not influence outside blade It sees, and reduces the cleaning time of mold, in addition improve service life and improve the quality of workpiece machining surface.
Detailed description of the invention
Fig. 1 is the side structural schematic diagram of the utility model.
Fig. 2 is the top view of the utility model.
Specific embodiment
The utility model preferred embodiment is provided, with reference to the accompanying drawing the technical solution of the utility model is described in detail.
As shown in Figure 1 to Figure 2, the utility model simplify chip-breaker index lathe paring blade include cutter hub 1, chip-breaker 2, Supporting surface 3, identified surface 4, rake face 5, flank 6, circular hole 7, Circular Nose Cutting Edge 8, transitional edges 9, main cutting edge 10, chamfered edge 11, cutter hub 1 For diamond shape, the center of cutter hub 1 is equipped with circular hole 7, and four sides of cutter hub 1 are equipped with main cutting edge 10, the upper surface of cutter hub 1 It is surrounded by rake face 5, four surfaces all around of cutter hub 1 are equipped with flank 6, and the upper face center of cutter hub 1 is equipped with support Face 3,3 center of supporting surface are equipped with identified surface 4, and each rake face 5 is equipped with chip-breaker 2, and each point of a knife of cutter hub 1 is equipped with circular arc Sword 8 and transitional edges 9, Circular Nose Cutting Edge 8 are connected 10 with main cutting edge by transitional edges 9, and Circular Nose Cutting Edge 8, transitional edges 9 and main cutting edge 10 are Equipped with chamfered edge 11, in which:
Chip-breaker 2 includes chip breaking sword 21, crestal surface 22, joint face 23, and chip breaking sword 21 is connected by joint face 23 with crestal surface 22.
Screw thread 12 is equipped in the circular hole 7, it can be with fixed cutter body and according to service condition rotating blade, using meeting the requirements Knife face.
The rake face 5 is all made of the shape of similar wave with chip breaking sword 21, also can pole while increasing cutting edge strength Good chip breaking and control bits.
The chip-breaker 2 uses arcuate structure, and the angle change in slot not sharply reduces the generation of internal stress.
The identified surface 4 is increased the bearing area to blade, is improved the steady of support using internal recessed planar structure It is qualitative, accelerate the diffusion of heat of blade.
The working principle of the utility model is as follows: cutter hub is connected by circular hole with lathe, and the screw thread in circular hole is further solid Stationary knife body simultaneously rotates blade according to service condition, switches the knife face of damage, improves the service life of blade entirety.It is described disconnected It considers slot to be worth doing and uses arcuate structure, structure is simple, is readily produced.Angle change in chip-breaker not sharply, trench structure reduce in The generation of stress, reduces cutting temperature, improves blade service life, increases chip breaking range, and demould in compacted products When reduce mold sizing, both ensure that the beauty of blade, and be reduced the cleaning time of mold.The rake face and chip breaking sword Using the shape of similar wave, this shape increases cutting edge strength, undertakes chip breaking function in different cutting depth and the amount of feeding Can, control fractureing for chip.The crestal surface of chip-breaker effectively realize chip curling and chip outflow control while, Blade is set to be easy to be detached from blank, it will not disfiguring workpiece.The chamfered edge makes it increase the intensity of blade in process, prevents Only blade tipping, rupture, increase blade service life.The equivalent tool arc half that point of a knife partial arc sword and transitional edges are formed Diameter makes workpiece surface become smooth mellow and full, improves the surface quality of work pieces process.The supporting surface is an integral planar, Blade can be effectively supported, cutting force when blade uses can be effectively decomposed, improve the ability of blade antidetonation.The identified surface can All kinds of marks are stamped as needed, and will not generate any influence to blade support face, and its internal recessed planar structure, The bearing area to blade is increased, the stability of support is improved, accelerates the diffusion of heat of blade, further improves making for blade Use the service life.
In conclusion the utility model simplifies the index lathe paring blade chip-breaker simple shape of chip-breaker, it is readily produced, Demoulding convenience when being molded blank, and base blank will not be damaged, for a long time using powder will not be glued in rear mold, it both will not influence blade Appearance, and reduce the cleaning time of mold, in addition improve service life and improve the quality of workpiece machining surface.
Particular embodiments described above, the technical issues of to the solution of the utility model, technical scheme and beneficial effects It has been further described, it should be understood that the foregoing is merely specific embodiment of the utility model, not For limiting the utility model, within the spirit and principle of the utility model, any modification for being made, changes equivalent replacement Into etc., it should be included within the scope of protection of this utility model.
