Background technique
The abnormity channel swirler belongs to three-dimensional flow closed blisk, and blade profile is complicated, and wall is thin and holds in process
It is also easy to produce deformation, therefore three-dimensional flow blade or says that three-dimensional flow blade and wheel disc, wheel cap-type face are formed by the processing of inter-leaf flow channel
It is extremely difficult, have become world today's advanced manufacturing field and all is making every effort to solve the manufacturing technology hardly possible but without resolving
Topic.
Such special-shaped channel swirler processing method mainly has numerical control milling, precision die forging, electrical spark working in the prior art
Work and electrochemical Machining Technology.
Numerical control milling: multi-axis NC milling processing at present is most conventional integral wheel manufacturing method, particularly with abnormity
Channel swirler processing, usually from prefered method.The numerical control milling of special-shaped channel swirler, it usually needs in the number of 5 axis linkage
It is carried out on control lathe, technology relative maturity.Milling is easy for those materials and the number of blade is less, inter-leaf flow channel is larger, i.e.,
The relatively good special-shaped channel swirler of cutter accessibility can use the direct overall processing of multi-axis NC milling.But manufacturing process
In, material-removal rate is very high, and complex art difficulty is very big, some using the different of the hard-cutting materials such as titanium alloy, high temperature alloy
Shape channel swirler, numerical control milling are extremely difficult.
Precision die forging: precision die forging single blade can be with fairly close final shape, and strengthens due to forging, Blade Properties
It increases with intensity.But special-shaped channel swirler complex geometry, production process is complex, technical difficulty is larger,
So that the processing is difficult to become final processing technology.Currently, precision die forging is used as blank method of producing more.

It is suitable for the workpiece for processing Low rigidity workpiece and Special complex shape.Currently, spark erosion technique has reached high-precision, low surface
Roughness, the level without face crack.Though needing to change electrode, electrical discharge machining due to having export license in process
The great workpiece of bending, such as special-shaped channel swirler, has apparent advantage.In the processing of special-shaped channel swirler,
Since size is small, structure is complicated and material difficulty is processed, and conventional numerical control milling, which is difficult processing, can not even process, and be processed into
This is very expensive；And hot investment casting can be used for the simple integrated member of some structures, but it is difficult to complicated close
The manufacture of formula integrated member.It therefore is to solve the problems, such as that enclosed integrated member is processed, it is necessary to seek new processing method to mend
Fill the deficiency of traditional processing.So the technical deficiency of traditional processing, electric spark has been effectively relieved in the application of spark erosion technique
Processing reaches processing purpose by discharge removal material, and the machinability and mechanical property of material are not related, thus is suitable for hardly possible
Cut the processing of material.
Electrode clamping device designs electrode mainly in the integral blade disk with complete air inlet/outlet in the prior art
It is from two position disengaging to process complete molding cavities channel, it is big that electrode can be made volume, or even only needs a feeding side
It is processed to by multiple electrodes, and this method is needed to the individually designed electrode of the leaf dish of special model and fixture, the system of electrode
It is very big to make and modify the time and efforts expended, for the swirler product of small size, such as radius 20mm, outlet stomatopod
It reaches deep and can not arrive at.
