Description
Technical field
The invention belongs to booster technical field, is related to a kind of cutting tool and processing method of nozzle outer shroud.
Background technology
Nozzle outer shroud is the significant components of nozzle ring, and the important workpiece of booster, and it is at work the same as nozzle ring, spray
Together, the common import for completing turbine combustion gas (waste gas) distributes, controlled the size of the flow direction and flow of air-flow to nozzle inner ring, directly
Connect control, influence the rotating speed of rotor assembly, have influence on the power and performance of booster, so the quality assurance of nozzle ring is very heavy
Will, the especially processing and quality assurance of nozzle outer shroud, but for many years, the crudy of nozzle outer shroud is never found
Good method, Reliable guarantee.
As depicted in figs. 1 and 2, its big end is cylindrical step 21 to the structure of nozzle outer shroud, and its small end is cylindrical annular groove 22,
There is an end-face hole 23 its big end end face, and existing nozzle outer shroud processing method is as follows：→ 30 rough turn big ends are examined in 10 heat treatments → 20
The rough turn small end endoporus of endoporus and end face → 40, the big end endoporus of the smart car of end face and cylindrical → 50 half, the smart car of end face and cylindrical → 60 half
Small end endoporus, smart car small end endoporus → 90 of the big end end face of the smart car of end face and cylindrical → 70 and cylindrical → 80 bore big end end-face hole →
100 blunt-edgeves, burr.
There is following problem in existing processing method：
1. in 60 half smart car small end endoporus, end face and cylindrical middle car annular groove, selection press from both sides cylindrical then gripping section it is too short and
Can't clip workpiece, and in the turning process of annular groove, gripping section wall thickness is constantly thinning with processing, along with turning to workpiece
Stress impact, easily cause workpiece and throw away, security incident occurs；Selection support endoporus carrys out car annular groove, although gripping section increases
It is long, but as support zone wall thickness is constantly thinning in processing, can equally cause workpiece to throw away the generation of accident, and it is maximum to the greatest extent
Power is tensioned claw and supports hole machined by force, again work pieces process can be caused clamping deformation occur, do not reach technological requirement size and
Required precision；
2. in 30 rough turn big end endoporus and end face, casting reality, because the small end wall of blank is thin, casting are not fully taken into account
The flow channel of metal liquid is narrower during making, not simple filler, and causing small end stomata, burning into sand, few meat etc. occur can not be true
The defects of determining, this allows for cast blank and actually gap be present with theory calls, so workpiece is more because of small end defect, nothing
Allowance and scrap, bring larger economic loss.
The content of the invention
