Description
Technical field
The present invention relates to centrifugal vapor compressor field, particularly relate to a kind of centrifugal vapor compressor and expand
The manufacture method of depressor.
Background technology
Centrifugal vapor compressor is to re-use the energy of the indirect steam that its own produces, thus reduces
A power-saving technology of energy demand to external world.Centrifugal vapor compressor is that heat recovery system is to producing
Live steam improves the key equipment of steam pressure by compression.Its operation principle is: calm the anger
Impeller rotates on the axle of compressor, enters the gas of compression impellor by with rotation, subsequently into diffusion
In device, it is required pressure by the speed-shifting of gas in diffuser.In recent years, along with saving energy
Source is increasingly paid attention to, and centrifugal vapor compressor is more widely used.
Centrifugal vapor compressor is made up of rotor and two parts of stator.Rotor be by impeller, main shaft,
The parts such as balancing frame, thrust disc form, and stator is by parts such as diffuser, bend, return channel, spiral cases
Composition.The function of diffuser is mainly effectively turning from the impeller air-flow with bigger kinetic energy out
Turn to pressure energy.So, the quality of diffuser workmanship directly affects the height of the pressure energy of conversion.
Existing diffuser manufacture method due at blade milling surplus a lot, expand after disposable milling blade
Depressor deformation is relatively big, and the vane type line profile tolerance after machining is poor；Face deformation causes diffuser simultaneously
Perpendicularity between end face and hole, location is poor；It addition, existing diffuser manufacture method is due at half finish turning
Whole connecting holes are processed with before finish turning end face, when subsequent turning end face because being interrupted cut,
The amount of feeding and bite are the least every time, and working (machining) efficiency is slow, and the vibrations of tool wear and lathe are relatively
Greatly, the precision of lathe is affected.
Summary of the invention
For in prior art, the vane type line profile tolerance of diffuser is poor, hanging down between end face and hole, location
The technical problem of straight degree difference；Further, for prior art is first processed after connecting hole turning end again,
Interrupted cut causes that efficiency is low, tool wear big and affects the technical problem of lathe precision, and the present invention carries
For the manufacture method of a kind of centrifugal vapor compressor diffuser, by rough milling blade passage, remove great Yu
Amount, then half finish-milling, the most again finish-milling blade passage, reduce the deflection of diffuser after milling blade,
Avoid the impact on subsequent handling, improve the vane type line profile tolerance of diffuser and end face and location
Perpendicularity between hole；It addition, only machined hole, end face two location before half finish turning and finish turning end face,
Improve working (machining) efficiency when half finish turning and finish turning end face, reduce the abrasion to cutter.
To achieve these goals, the technical scheme is that
The manufacture method of a kind of centrifugal vapor compressor diffuser, comprises the following steps:
A. blank is heat-treated；
The end face of the big end of the most rough turn diffuser, cylindrical, endoporus and second step end face；
The end face of the most rough turn diffuser small end, cylindrical, endoporus and first step end face；
D. in the end face edge of big end, bore milling hole, location, milling tool is installed, and by location Kong Ding
Position, rough mills the blade on small end；
E. end face, cylindrical, endoporus and the first step end face of half finish turning diffuser small end；
F. end face, cylindrical, endoporus and the second step end face of the half big end of finish turning diffuser；
G., milling tool is installed, and is positioned by hole, location, finish-milling blade, after finish-milling completes, send three coordinates
Inspection；
The most after the assay was approved, big end and the end face of small end and first step end face draw boring center
Line；
I. centering center line, drilling and tapping；
J. the end face of the big end of finish turning diffuser and endoporus；
K. file is repaiied bottom blade passage；
L. blade is carried out penetrating inspection.
Further, in step b, four paws folder small end cylindrical, centering, the end face of the big end of rough turn diffuser,
Cylindrical, endoporus and second step end face.
Further, in step c, cylindrical held greatly by four paws folder, by flat end face greatly, in the big end of centering car
Hole, the end face of rough turn diffuser small end, cylindrical, endoporus and first step end face.
Further, in step e, cylindrical held greatly by soft three-jaw folder, by flat end face greatly, in the big end of centering car
Hole, end face, cylindrical, endoporus and the first step end face of half finish turning diffuser small end.
Further, in step f, soft three-jaw folder small end cylindrical is by flat first step end face, little with car
End endoporus jerk value is less than or equal to centering on the basis of 0.015mm, the end face of the big end of half finish turning diffuser, outer
Circle, endoporus and second step end face.
Further, in step i, big end end face is downward, centering center line, at the first step of big end
Press figure holes drilled through on end face, small end end face bores stepped hole；Turn-over, centering center line, at end greatly
Tapping female bore is bored by figure on face.
Further, in step j, soft three-jaw folder small end cylindrical, by flat first step end face, with car
Big end endoporus jerk value is less than or equal to centering on the basis of 0.015mm, finish turning diffuser big end end face.
The method have the benefit that:
1, blade milling be divided into rough mill, finish-milling processing, remove big surplus, the most again finish-milling blade when rough milling,
Solve the technical problem that in prior art, disposable milling surplus causes more greatly diffuser to deform, reduce
The impact on subsequent handling of the deflection after blade milling, improve the molded line profile tolerance of diffuser vane with
And the perpendicularity between end face and hole, location；
2, owing to only machined hole, end face edge two location before half finish turning diffuser end face, at half finish turning
Being continuous cutting during end face, each amount of feeding and bite are relatively big, improve working (machining) efficiency, reduce cutter
The abrasion of tool and the damage to lathe；
3, by finish turning diffuser big end end face, eliminate and hold greatly near end face aperture because of what boring caused
Local deformation.
