The method of work FV520B material 3 d impeller.
In order to solve the above technical problems, finishing FV520B material with solid carbide the present invention provides a kind of
The method of 3 d impeller, includes the following steps:
After the blank of reel milling 3 d impeller carries out roughing, it is desirable that reserve the machining allowance of 0.7-1mm in blade unilateral side；
To blade fillet back chipping, the finishing of blade inlet edge round end, impeller hub finishing；
Using long-blade tapered bulb whole hard alloy wave blade milling cutter to blade semifinishing, 0.2- is reserved in blade unilateral side
0.5mm allowance for finish；
Blade is finished using long-blade tapered bulb solid cemented carbide milling cutter, vane thickness is worked into design size.
Further, gap width of the cutter bulb apart from wheel hub is set as during the blade fillet clean-up machining
0.5mm, gap width of the cutter bulb apart from wheel hub is set as 0.7mm, the blade finishing during the blade semifinishing
Gap width of the cutter bulb apart from wheel hub is set as 0.9mm during work.
Further, gap width of the cutter bulb apart from impeller round end is set in the blade semifinishing and finishing passes
It is set to 1mm.
Further, long-blade tapered bulb whole hard alloy wave blade milling cutter used in the blade semifinishing process
Probe-radius be 8mm, the speed of mainshaft be 1300-1700 revs/min, the amount of feeding be 400-600 mm/min.
Further, the bulb of long-blade tapered bulb solid cemented carbide milling cutter used in the blade finishing passes
Radius is 8mm, and the speed of mainshaft is 900-1100 revs/min, and the amount of feeding is 400-500 mm/min.
A kind of method with solid carbide finishing FV520B material 3 d impeller provided by the invention, can be with
Applied to ruled surface reel milling 3 d impeller, this method replaces the long sword high-speed steelknife of taper half using solid carbide
Finishing and finishing 3 d impeller blade, since solid carbide has high hardness, intensity and toughness preferably excellent
Performance, therefore solid carbide is used to process FV520B material 3 d impeller, the amount of feeding is big, and cutting speed is fast, than existing
Some long sword high-speed steelknife cutting speeds of taper are 5 to 7 times high, and the time for processing blade is made to shorten to original 1/6th, save
Time about accounts for the Impeller Machining time 15%-18% of (roughing and finishing summation), substantially increases adding for 3 d impeller
Work efficiency rate.Moreover, the 3 d impeller surface quality after processing is preferable, vane thickness is uniform, and dimensional accuracy is higher.Meanwhile it is whole
Hard alloy cutter also has the excellent performances such as wear-resisting, heat-resisting, corrosion-resistant, and therefore, the service life of hard alloy cutter is than cone
High 5 to 80 times of the service life of long sword high-speed steelknife is spent, it can be achieved that one the service life of 10 impellers of tool sharpening, is enterprise
Large number of equipment, manpower and the cost of charp tool have been saved, Business Economic Benefit is significantly improved.
