Description
Technical field
The present invention relates to a kind of processing method, the processing method of a kind of complex-curved integral wheel.
Background technology
In aero-engine field, impeller is one of critical piece of power generation, but owing to the profile of impeller is more multiple
Miscellaneous, it is substantially all and is made up of curved surface, general processing method is to assemble after single impeller is processed molding, although this
Method difficulty of processing is relatively little, but the bad unification of size of every a piece of blade, and its intensity also can be affected simultaneously, the life-span
The longest；At present due to the development of process equipment, generally using overall processing technology, its general operation is: casting → super
Sonic testing → polishing → inspection.But the intensity that this method makes impeller is low, the mold shape of processing is complicated, manufactures difficulty, leaf
Sheet precision it is difficult to ensure that, dynamic balance performance is poor, and the production cycle is long.
Summary of the invention
Problem to be solved by this invention is the processing method of a kind of integral wheel, makes the good processing accuracy of impeller, efficiency
Height, intensity is big, and dynamic balance performance is good.
The concrete grammar that the present invention uses is: forging molding → roughing → ultrasonic inspection → destressing → polish base
Standard → polish endoporus → blade processing → polishing → inspection.Described blade processing operation include blade roughing work step,
Blade polish work step, blade passage polish work step, big blade lead angle polish work step, vanelets lead angle polish work step.
Blade processing operation of the present invention uses every stroke index and can complete to add integral blade
The numerical control machining center of work work five-axle linkage, the UCP800 numerical control machining center that such as the bright company of Switzerland's Mick produces.It is special
Point is to have once follow procedure requirement to complete the roughing all work steps to polish of blade, and can follow procedure will automatically
Ask and carry out tool changing.
The blank that the present invention uses is forging molding, and the intensity of the integral wheel being processed into also can the product of relatively casting
Intensity is high；Use digital control processing, the parts size precision after processing can be made good, and need not mould and the clamps of complexity,
Process-cycle is short, and efficiency is high.It addition, this manufacturing procedure is to carry out overall vaned processing, therefore by hole, a location
Size uniformity between blade is good, and then dynamic balance performance is high.In the course of processing, it is provided with directional hole and part can be made to exist
