Summary of the invention

The object of this invention is to provide the processing method of a kind of aero-engine compressor without installing plate stator blade, to ensure blade profile profile tolerance, improve working (machining) efficiency, shorten the process-cycle.

For achieving the above object, the present invention adopts following technical scheme:

1) milling inlet and outlet limit: adopt fine forge piece as without installing plate stator blade blank, blank comprises blade, be positioned at the exhaust limit of blade side, be positioned at the leading edge of blade opposite side, be positioned at first false boss of blade one end and be positioned at the second false boss of the blade other end, wherein blade comprises blade tip and blade root, blade tip connects the first false boss, blade root fastenings second false boss, the second false boss end face is that sharf is to benchmark;

With the positioning and clamping processing gas inlet limit, basin side of the first false boss, the second false boss, the second false boss end face and blade and exhaust limit on CNC milling machine, leading edge stays 0.05mm ~ 0.15mm surplus with exhaust limit;

2) polishing inlet and outlet limit: polishing leading edge and exhaust limit, makes the size and dimension on leading edge and exhaust limit meet designing requirement;

3) Linear cut blade tip and blade root: with the basin side of blade, the first false boss, the second false boss and the second false boss end face positioning and clamping on numerically controlled wire cutting machine, processing blade tip and blade root, remove the first false boss and the second false boss;

4) pincers are repaiied: pincers repair blade tip and blade root, removal step 3) in be retained in Linear cut remelted layer on blade tip and blade root, and make the surface roughness of blade tip and blade root meet designing requirement.

The leading edge of described blank has 2mm ~ 3mm allowance with exhaust limit.

Described step 2) in polishing on polishing machine, adopt bob and nylon wheel to carry out.

Described step 4) employing file repaiied by middle pincers and sand paper carries out.

Compared with prior art, the beneficial effect that the present invention has: the invention proposes the improvement processing method of a kind of aero-engine without installing plate stator blade, repair by carrying out milling intake and exhaust limit, polishing intake and exhaust limit, Linear cut blade tip blade root and pincers to finish forge blank, processing obtains aero-engine without installing plate compressor stator blade.The present invention has the following advantages: 1) the method adopts finish forge blank, ensure that blade type profile tolerance of a surface and surface quality, makes the blade obtained meet designing requirement; Because blank adopts fine forge piece, so make the qualification rate of obtained blade high, overcome the working (machining) efficiency that causes owing to adopting die forging blank or plate in prior art and the low problem of qualification rate; 2) method work flow provided by the invention is simple, effectively improves working (machining) efficiency, shortens the process-cycle.
