Description
Technical field
The utility model relates to a kind of novel for high temperature alloy semifinishing turning carbide chip.
Background technology
High temperature alloy has single austenitic matrix tissue, has higher elevated temperature strength, anti-oxidant and hot corrosion resistance, the combination property that good fatigue behaviour, fracture toughness and plasticity etc. are unique, and this alloy is widely used in aero-engine.But this material cutting force in process is large and concentrated, cutting temperature is high, chip is difficult to fracture, and then cause tool wear, badly broken, cutter life significantly shortens, and reduces the reliability of cutter, thus affects surface integrity and the machining accuracy of workpiece.
Summary of the invention
The purpose of this utility model is to provide a kind of triangle high temperature alloy semifinishing turning carbide chip, with the problem in solving existing blade cutting temperature being high when processing high temperature alloy, cutting force is large, machined surface quality is poor, chip is not easily discharged etc.
The utility model for solving the problems of the technologies described above taked technical scheme is: described blade comprises cutter hub, cutter hub is equilateral triangle, the centre bit of cutter hub is equipped with circular hole, three limits of cutter hub are provided with main cutting edge, at cutting edge there is blunt round radius in place, cutter hub rake face is provided with chip-breaker, chip-breaker is made up of straight line and circular arc, point of a knife place is made up of three sections of circular arcs, anti-attrition groove is provided with in point of a knife front end and main cutting edge place, before anti-attrition groove, be provided with boss, main cutting edge, Circular Nose Cutting Edge place are equipped with chamfered edge.
The utility model has following good effect: the utility model blade is provided with anti-attrition groove at point of a knife rake face place, anti-attrition groove is not process in the production process of blade, it is by the actual demand of operator, before using blade, utilizes Laser Processing or spark technology to produce.In process, when using cutting fluid, in anti-attrition groove, there is cutting fluid, lubrication can be played, reduce the effect of friction, the temperature in main cutting force and cutting edge region can be reduced.The nose radius of blade is made up of three sections of circular arcs, which increases the contact length between blade and workpiece, can carry out work, obtain good surface quality in high feed rate situation.In process, the chamfered edge at cutting edge place adds cutting edge strength, and cutter life is extended.Rake face is provided with the grooved be made up of straight line and circular arc, when the different amount of feeding and cutting depth, is conducive to the curling of chip and fractures, effectively controlling the outflow of chip, improving machining efficiency.This trench structure is reasonable in design, reduces the cutting temperature of working angles, cutting force, improves the fracture energy of chip in high temperature alloy working angles, improves the machined surface quality of workpiece, improves cutting-tool's used life.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model; The top view of Fig. 2 utility model; Fig. 3 is the A-A sectional view of utility model, and Fig. 4 is the B-B sectional view of utility model, and Fig. 5 is the partial enlarged view at I place in Fig. 1.
Detailed description of the invention
Detailed description of the invention one: composition graphs 1 illustrates present embodiment, the blade of present embodiment comprises cutter hub 1, cutter hub is equilateral triangle, circular hole 1-1 is had at the center position of cutter hub, three limits of cutter hub 1 are provided with main cutting edge 3, the feature of blade is be provided with chip-breaker 2 on the rake face of cutter hub 1, the end face of chip-breaker is made up of several sections of circular arcs, the point of a knife position of cutter hub 1 has the circular arc of three sections of different radiis to form, anti-attrition groove 6 is provided with at point of a knife leading portion, boss 5 is provided with before anti-attrition groove, it is higher than rake face, lower than the height of chip-breaker, the effect strengthening point of a knife position intensity can be played, main cutting edge 3 and Circular Nose Cutting Edge 7 place are equipped with chamfered edge 4.
Detailed description of the invention two: composition graphs 1 illustrates present embodiment, the negative rake γ of the main cutting edge 3 of present embodiment
0be 7
o, relief angle α is 0 °, the anterior angle γ of chamfered edge 4
01be 8
o, the width of chamfered edge is 0.2mm, and corner radius 7 is 0.8mm.This structure effectively reduces cutting temperature, the cutting force of working angles, improves the fracture energy of chip in high temperature alloy working angles, improves the machined surface quality of workpiece, improves cutting-tool's used life.
