Description
Technical field
The utility model is related to a kind of wheel groove milling cutter, and in particular to a kind of wheel of the hard alloy material with circular arc chip dividing groove type
Slotting cutter.
Background technology
Turbo rotor groove process tool is wheel groove milling cutter, and the wheel groove milling cutter material that current company uses is powder metallurgy
High-speed steel, the shank of the wheel groove milling cutter has screw, needs to remove on cutter chuck slave bed during handling milling cutter, then uses screw
Cutter and chuck are connected；The wheel groove milling cutter, which occurs, allows knife phenomenon, and relieving amount is between 0.20~0.25mm, the circle wheel of milling one
, it is necessary to again to knife, add the non-cutting time of adjustment rotor after groove；The rotating speed of the wheel groove milling cutter be 420~450r/min,
The amount of feeding is 42~45mm/min, and the slot number of most processing rotor races is 30~32 (7.2 meters).
Utility model content
The utility model provides a kind of wheel groove milling cutter of the hard alloy material with circular arc chip dividing groove type for drawbacks described above.
The utility model adopts the technical scheme that to solve above-mentioned technical problem：
A kind of wheel groove milling cutter of the hard alloy material with circular arc chip dividing groove type of the present utility model, the wheel groove milling cutter includes
Staight shank, transition shoulder, cutting edge part, staight shank, transition shoulder, cutting edge part set gradually and are made into integration from left to right,
Staight shank and transition shoulder are cylinder, and the diameter of staight shank is less than the diameter of transition shoulder, and cutting edge portion is divided into cone structure, and
Cutting edge portion of its outer diameter on cone structure is less than on the diameter of transition shoulder side, cone structure is provided with four along longitudinal direction
Chip pocket, the chip pocket is dextrorotation skewed slot, and the gradient of dextrorotation skewed slot is 3 °~5 °, and cutting edge rake face is 0 ° of anterior angle, cutting
Knife face is knife face after teeth after sword, and the tread of cutting edge is 4mm~6mm.
The utility model has the advantages that compared with prior art：
First, the staight shank structure of the utility model design, need to only loosen chuck hydraulic system, and cutter just takes out from chuck,
The non-cutting time for installing cutter is saved., easy behaviour simpler compared to the Blang Sharp handle of a knife installation way of high-speed steel wheel groove milling cutter
Make.
2nd, the utility model uses whole hard alloy material, and whole hard alloy wheel groove milling cutter relieving amount is in 0.05mm
Within, after the circle race of milling one, it is not necessary to again to knife, reduce the non-cutting time of adjustment rotor.
3rd, whole hard wheel groove milling cutter is improved a lot compared to the machined parameters that high-speed steel wheel groove milling cutter is processed, and overall hard is closed
The rotating speed of golden wheel groove milling cutter is 600~620r/min, 63~65mm/min of the amount of feeding, and the slot number of most processing rotor races is 75
~78 (17.5 meters), while number of changing knife is reduced in processing, overall efficiency improves more than 50%.
4th, the product surface finish of whole hard alloy wheel groove milling cutter processing is better than the processing effect of high-speed steel milling cutter,
Improve the crudy of rotor.
5th, 0 ° of anterior angle is to ensure that whole hard alloy wheel groove milling cutter can multiple reconditioning rake face, and cutter molded line essence
Degree meets required precision.
6th, the utility model uses the benefit of teeth relief angle：One side tool in cutting sword is greatly reinforced, and is improved cutter and is used
In the life-span, on the other hand, during using teeth relief angle, cutter grinding rake face, cutter molded line precision is changed very little, and cutter is through 5-6 times
Reconditioning rake face, cutter molded line precision remains to meet required precision.
