Description
Technical field
The utility model relates to a kind of milling cutters, more particularly, to a kind of 5 blade milling cutter of whole hard alloy.
Background technique
The unique design of screw compressor becomes world today's energy-saving compressor.Screw compressor mainly runs part
Whirlpool disk only has dirty conjunction not wear, thus longer life expectancy, is known as freedom from repairs compressor.
Screw compressor is a kind of fluid machinery that gas compression is realized by means of volume variation.Dynamic fixed scroll is to provide
The core part of gas compression, the performance of its processing precision direct influence compressor.The quality of sound disk processing precise, mainly
It is embodied in the relevant shape of vortex molded line, position and dimensional accuracy, mainly includes scroll molded line profile tolerance, verticality, end face
And soffit plane degree, the depth of parallelism and scroll wrap wall thickness and height, most of these rigorous are selected in low-light rank
Lathe, fixture, especially cutter produce bigger effect its meeting.
Shape feature based on the orbiting and fixed scroll, processing is mainly based on milling, and disk body required precision itself is higher, institute
It is corresponding also very high with the requirement to cutter.Scroll molded line tooth form belongs to deep trouth thin wall shape, and processed depth over width ratio reaches
Between 1:3-1:4, in this case, tool in cutting sword diameter is small, extension elongation is big, and stress is easy to happen radial allow in process
Knife and vibration influence the verticality and roughness of tooth wall.In cutter manufacture industry, this is a no small problem.
The cutter used currently on the market, it is ensured that engineering manufacturing capacity mostly uses greatly big core thick, multiple tooth, precise polished
Cutting edge, the verticality and the depth of parallelism of scroll molded line curved surface are solved by structural rigidity, and underrun mirror finish is accurate
Grind the flatness to realize bottom surface, roughness.Under processing request may be implemented in such production method, but efficiency is very low,
And cost is very high.
Utility model content
The utility model is to provide a kind of 5 blade milling cutter of whole hard alloy, mainly solves present in the prior art
Probability resonance that milling cutter generates in milling process, vibration knife probability are larger, and tool life is lower, and operating condition rigidly allows knife unsmooth
Poor, the error of perpendicularity is larger, under processing efficiency is very low, the technical issues of production cost is higher equal.
Above technical problems of the utility model are mainly solved by the following technical scheme:
One end of 5 blade milling cutter of whole hard alloy of the utility model, including shank, the shank is equipped with milling cutter sheet
Body, cutter body are equipped with the Zhou Ren of 5 Spiral distributions, and on the cylindrical surface of cutter body the part of high core 0.30-0.40mm,
All edge clearance angle of the circular arc in the section of 0.05-0.08mm wide as cutter hub, the asymmetry at angle between five swords that all sword end faces is formed
Degree is less than or equal to 5o.The utility model is using the weak asymmetric Cutting Edge Design of odd number, to reduce the probability generated in milling process
Property resonance.Circumference does positive cone, i.e., small tail is big, and the difference in diameter of 8um is required in 15mm length.
Preferably, angle is respectively as follows: 76,71,68,73,72 between five swords that all sword end faces are formed.Sword
Between angle distribution angle clockwise (since 180 directions): 180,104,33, -35,108 directions, angle is respectively as follows: between sword
76,71,68,73,72.Micro eccentric cylinder fitting relief angle, the design such as Contrary compensation back cone have been carried out to all swords；?
To alleviate the knife probability that shakes, tool life also can be improved, compensation operating condition rigidly allows knife, corrects the error of perpendicularity.
Preferably, the first dish angle α and the second butterfly angle beta are respectively equipped on the end sword of the cutter body front end,
First dish-shaped angle is 3-5, and the second dish-shaped angle is 15-25 ', width 0.20-0.30mm.Hold sword in mal-distribution,
It is designed using double dish-shaped angles, small dish angle cooperates backlash rake face, carries out micro smoothing to bottom surface, big dish angle controls amount of interference
And wiper edges length.
Preferably, the backlash anterior angle 5 of the end sword of the cutter body front end, knife face on entire a line backlash, most
It is 0.25mm wide at width, is located at end face the first relief angle width in the range of backlash anterior angle.
Preferably, the root of the cutter body and the junction of shank are equipped with arc caulking groove, set in arc caulking groove
There is serrated slot, is filled in arc caulking groove, serrated slot and reinforces alloy-layer.The utility model is in the junction of cutter body and shank
Provided with alloy-layer is reinforced, the intensity of entire milling cutter can be reinforced in this way, it is prevented to be broken when in use, prolonged the service life.
The bonding strength for reinforcing alloy-layer can be increased using arc caulking groove, serrated slot, reinforcement alloy-layer is commercial product.
Therefore, the utility model structure is simple, and manufacture is easy, to the orbiting and fixed scroll to scroll molded line in Precision Machining
Profile tolerance, verticality, end face and soffit plane degree, roughness, there is relatively good effect, can cooperate lathe may be implemented compared with
High process capability.
