Thaum engineers qhia peev casting Tuam Tshoj Hoobkas cov kev pabcuam rau lub siab hydraulic li qub lossis cobalt-alloy twj tso kua mis, lawv tsis yog tsuas yog muab cov hlau-lawv tau ruaj ntseg ruaj khov nyob rau hauv 300-bar loads, microstructure kev ncaj ncees tom qab kev kho cua sov, thiab tag nrho batch traceability mus rau lub yaj tooj. Qhov ntawd yog lub hauv paus - tsis yog qhov zam.
Peb tau pom ntau qhov chaw nres tsheb ntawm cov qauv qauv vim tias lub tsev casting tsis tuaj yeem tuav ± 0.05 hli ntawm AMS 5387 cobalt alloy nozzle bore-los yog phem dua, xa ib qho "tso ntawv pov thawj" T800 alloy nrog cov nplej tsis sib haum thoob plaws thaj tsam kev ntxhov siab. Lub hauv paus ua rau? Fragmented muaj peev xwm. Lub khw muaj zog hauv cov xuab zeb casting feem ntau tsis muaj peev xwm ntau qhov CNC rau qhov kawg contouring. Ib tus kws tshaj lij hauv superalloy machining tsis tshua muaj peev xwm tswj cov peev txheej tsim los yog dewaxing ramp profile uas txhais tau tias qhov chaw tiav thiab qhov porosity.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. daws qhov no los ntawm kev sib koom ua ke nrog peb txoj kev nruj nruj: kev nqis peev zoo tshaj plaws, kev ua haujlwm siab CNC machining, thiab metallurgically validated tiav - tag nrho nyob rau hauv ib lub ru tsev ISO-raws li Qingdao. Tsis muaj handoffs. Tsis muaj qhov sib txawv interface. Tsis muaj rework cycles tshwm sim los ntawm dimensional drift ntawm casting shrinkage thiab post-machining kam rau ua stack-up. Lawv cov txheej txheem pib nrog cov ntaub ntawv pov thawj - AMS 5387 cobalt-nickel alloy billets tau txais los ntawm cov neeg muag khoom kuaj xyuas, txheeb xyuas thaum tau txais kev siv OES spectroscopy thiab tensile kuaj ib ASTM E8. Txhua ntau nqa cov ntaub ntawv tshuaj lom neeg thiab cov cuab yeej cuab tam, khi ncaj qha rau cov khoom tiav ntawm laser-etched ID codes.
Lawv cov peev txheej casting ua haujlwm nyuaj geometries uas cov pa machining ib leeg tsis tuaj yeem ua tiav kev lag luam - lossis tag nrho. Xav tias piston twj tso kua mis lub tog raj kheej nyob nrog kev sib xyaw ua ke ntawm cov dej txias, lub siab lub cev nrog cov nested concentric bores, los yog winch center ncej rollers featuring asymmetric bearing journals thiab internal keyways. Cov no tsis yog cov khoom pov tseg thiab tsis nco qab lawm. Txhua tus tau tswj xyuas dewaxing, precision ceramic plhaub firing, nqus-pab pouring, thiab qeeb-txias solidification kom txo qhov seem seem. Tom qab ntawd los ntawm qhov sib txawv tiag tiag: hauv tsev 5-axis CNC machining tam sim ntawd tom qab kev kho cua sov, siv calibrated CMMs thiab optical profilometers los xyuas GD&T callouts - nrog rau qhov tseeb txoj hauj lwm, cylindricity, thiab nto roughness Ra ≤ 0.8 μm qhov chaw ua hauj lwm sealing nyob ntawm nws.
- Cov ntaub ntawv zoo tshaj li cov ntaub ntawv: Lawv tsis tsuas yog "siv" cobalt alloys - lawv nkag siab li cas T800's carbide nag lossis daus tus cwj pwm hloov nrog cov cua txias, yog vim li cas AMS 5387 qhov kub hardness degrades saum 850 ° C thaum lub sij hawm kev ntxhov siab, thiab yuav ua li cas kho lub plhaub thickness thiab preheat kub los tiv thaiv micro-shrinkage nyob rau hauv 12-mm phab ntsa qhov nozzle ntawm non-standard.
- Tsis muaj "standard" tiav kev cuam tshuam: Qhov kev ncaj ncees ntawm qhov chaw tsis yog qhov kev xav tom qab. Kev txhaj tshuaj peening tsis yog tuned ib feem geometry thiab loading hom. Passivation rau stainless hlau castings ua raws li ASTM A967, nrog rau kev kuaj tooj liab sulfate rau kev kuaj hlau dawb - tsis yog kev kuaj pom.
- Tsim-rau-manufacturability built-in: Thaum cov neeg siv khoom xa cov duab kos nrog kev ua siab ntev ntawm cov phab ntsa nyias nyias, lawv cov engineers chij muaj kev pheej hmoo ntxov - tsis yog nrog cov ntawv sau zoo li "tej zaum yuav nyuaj," tab sis nrog cov kev xaiv tshwj xeeb: "Txo phab ntsa thickness ntawm 2.3 hli mus rau ≥3.0 hli kom tsis txhob muaj lub plhaub distortion thaum lub sij hawm dewaxing," los yog "Shift datum B rau machined nto es tsis txhob as-cam khwb cia."
Qee tus tuaj yeem sib cav hais tias cov khoom lag luam tawm sab nrauv qhia txog kev pheej hmoo ntawm cov saw hlau. Tab sis hauv kev xyaum, qhov kev pheej hmoo loj dua nyob rau hauv kev xaiv tus neeg muag khoom yam tsis muaj kev sib koom ua ke. Peb tau taug qab kev xa khoom thoob plaws 47 xaj tshaj 18 lub hlis: 98.3% ua tiav raws sijhawm rau nruab nrab-ntim khiav (50-500 pcs), nrog xoom xa khoom lig vim yog cov txheej txheem sab hauv. Vim li cas? Vim tias casting, machining, thiab QA ua haujlwm tawm ntawm cov sijhawm tsim khoom sib koom - tsis cais cov hnub ua haujlwm. Thaum tus neeg siv khoom xav tau kev lees paub sai ntawm qhov hloov kho GD&T cov phiaj xwm, kos duab rov ua dua yog nyob rau hauv 48 teev - tsis yog ob lub lis piam.
Qhov no tsis yog hais txog tus nqi qis tshaj. Nws yog hais txog cov txiaj ntsim tau los. Lub siab valve lub tsev nyob ntawm no muaj sia nyob 20,000 cycles ntawm 280 bar tsis muaj zog tawg vim tias lub plhaub peev tswj kev taw qhia kev ruaj khov - thiab kev ua haujlwm tom qab cam khwb cia khaws cia compressive residual kev ntxhov siab nyob rau hauv lub bore nto. Lub cobalt alloy ntsaws ntsaws ruaj ruaj ntawm 450 ° C vim tias thermal expansion coefficients tau sib tw thoob plaws lub rooj sib txoos - tsis yog kwv yees los ntawm phau ntawv muaj nuj nqis. Cov txiaj ntsig no tau los ntawm kev ua tsawg dua, tab sis ua lawv nrog cov ntaub ntawv rov ua dua, kev siv hlau tsis zoo, thiab xoom kam rau siab rau kev tsim khoom raws li kev xav.
Rau cov engineers qhia qhov chaw uas tsis ua hauj lwm txhais tau hais tias downtime, kev nyab xeeb kev nyab xeeb, los yog kev cai tsis ua raws cai-peev casting Tuam Tshoj Hoobkas yuav tsum txhais tau ntau tshaj li thaj chaw. Nws txhais tau tias tswj. Traceability. Thiab kev ntseeg siab tias thaum koj lub twj tso kua mis sib dhos mus rau hauv online, qhov casting tsis yog tsuas yog nchuav - nws tau tsim los rau hauv lub neej.
