Thaum engineers qhia poob ciab casting pwm Hoobkas cov kev pabcuam rau lub hom phiaj tseem ceeb ntawm cov hlau tseem ceeb, lawv tsis yog yuav cov pwm xwb-lawv tab tom ua kom muaj qhov rov ua tau zoo dua qub, kev tswj hwm microstructural, thiab kev ntseeg tau ua haujlwm nyob rau hauv cov xwm txheej hnyav. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., peb tau tsim ntau tshaj 12,000 peev-cam khwb cia khoom rau hydraulic valve lub cev, cobalt-alloy twj nozzles, thiab piston twj tso kua mis lub tog raj kheej vaj tse-txhua qhov xav tau ± 0.05 hli kam rau ua, tag nrho cov khoom siv traceability, thiab kev kho cua sov-AMS. Qhov ntawd tsis yog theoretical muaj peev xwm. Nws yog dab tsi tshwm sim thaum koj khiav 47 sib law liag ntau ntau ntawm T800 cobalt-raws li castings yam tsis muaj ib tug batch rejection.
Vim li cas poob wax casting pwm Hoobkas xaiv hloov txhua yam - rau koj lub neej, tsis yog nws cov duab xwb
Cov pab pawg muag khoom feem ntau kho cov peev txheej ua "lub thawv dub" txheej txheem: xa cov duab kos, tos 6-8 lub lis piam, tom qab ntawd tshuaj xyuas. Tab sis nyob rau hauv high-pressure hydraulic systems los yog offshore roj & roj khoom, ib tug microporosity pawg nyob rau hauv lub siab valve lub rooj yuav ua rau cascading tsis ua hauj lwm. Peb tau pom peb cov neeg siv khoom rov qab los rau peb tom qab thawj tus neeg muag khoom ua tsis tiav - tsis yog vim lawv thawj tus neeg muag khoom tsis muaj khoom siv, tab sis vim lawv tau kho pwm tsim raws li kev hloov pauv, tsis yog thermal dynamics qauv. Peb poob ciab casting pwm Hoobkas pib nrog solidification simulation-tsis siv quav ciab qauv fabrication. Txhua qhov pwm kab noj hniav suav rau cov hlau tshwj xeeb shrinkage gradients, gating-induced turbulence, thiab localized cooling rates. Rau AMS 5387 cobalt alloy, uas txhais tau hais tias kho sprue geometry los ntawm 1.8 ° los tiv thaiv dendritic segregation ntawm lub rooj vag interface. Rau stainless hlau twj tso kua mis lub hauv paus, nws txhais tau tias embedding thermocouple ports ncaj qha mus rau hauv lub ceramic plhaub pwm kom validate lub sij hawm solidification lub sij hawm piv rau FEA kwv yees.
Koj tsis tas yuav muaj peev xwm "ntau" - koj xav tau kev tswj hwm kev sib koom ua ke uas nws tseem ceeb tshaj plaws
Qee tus neeg muag khoom outsource pwm ua, lwm tus outsource machining, thiab ntau outsource kub kho. Qhov kev sib cais ua rau qhov tsis sib xws: lub casting tuaj yeem dhau qhov kev soj ntsuam tab sis ua tsis tiav qhov kev sim hardness vim tias tus neeg siv lub tshuab hluav taws xob siv tus nqi sib txawv dua li qhov teev tseg. Ntawm peb qhov chaw ua haujlwm ISO-raws li Qingdao, tib pab neeg ua haujlwm pwm tsim, ceramic plhaub fabrication, precision CNC xov, thiab lub tshuab nqus tsev kho cua sov-tag nrho hauv ib lub ru tsev, nrog rau cov qauv ntsuas ntsuas. Thaum ib tus neeg siv khoom nyob sab Europe xav tau 240 lub siab valve lub cev hauv 316 stainless hlau nrog Ra ≤ 0.4 µm nto tiav ntawm cov dej ntws sab hauv, peb hla kev polishing theem nrab. Yuav ua li cas? Los ntawm machining lub ceramic plhaub pwm nrog 5-axis toolpaths replicated kawg contour tolerances - ces siv tswj dewaxing thiab burnout cycles los khaws cia qhov kev ncaj ncees los ntawm casting. Qhov tshwm sim: 98.7% thawj-dhau tawm tawm, xoom rov ua haujlwm, thiab xa khoom hauv 22 hnub es tsis txhob hais tawm 38.
Tus nqi tiag tiag ntawm "tus qauv" poob ciab casting pwm Hoobkas kev koom tes
Cov neeg siv khoom feem ntau nug: "Koj puas tuaj yeem phim peb tus neeg muag khoom tam sim no tus nqi?" Peb cov lus teb yeej ib txwm zoo ib yam: "Cia peb sim ob qho tib si." Xyoo tas los, peb tau khiav kev sim ib sab ntawm 18 qhov kev txiav txim hlau zoo tib yam - tib GD&T, tib yam khoom spec, tib lub qhov rais xa khoom. Tus neeg muag khoom tus nqi qis tau xa tuaj raws sijhawm - tab sis 31% xav tau kev sib tsoo tom qab kev sib tsoo kom tau raws li qhov profile kam rau ua. Peb muaj 92% kev lees txais ncaj qha rau kev sib dhos. Vim li cas? Lawv cov txheej txheem ua pwm siv phau ntawv siv quav ciab los ua ke; peb tus kheej siv automated txhaj tshuaj nrog lub sij hawm ntawm kab noj hniav siab xyuas. Qhov sib txawv ntawm 0.03 hli nyob rau hauv cov tub ntxhais kawm tsis tau tshwm sim hauv CMM cov ntaub ntawv txog thaum tom qab machining-thaum seem nqi ntaus $220 ib feem. Tus nqi tiag tiag tsis yog tus nqi tsev. Nws yog tag nrho cov nqi tsaws rau ib feem ua haujlwm, suav nrog kev tshuaj xyuas kev ua haujlwm, rov ua haujlwm seem, thiab teem caij pheej hmoo. Peb sau txhua qhov sib txawv - mus rau qhov tseeb qhov cub kub nkhaus rau txhua lub plhaub pwm batch - yog li koj paub tseeb tias vim li cas koj qhov ua tau zoo.
Dab tsi los tom ntej yog tsis muaj peev xwm ntau dua - nws yog kev paub txog kev sib sib zog nqus
Peb tab tom nthuav tawm peb cov khoom lag luam ploj casting pwm lub Hoobkas muaj peev xwm-tsis yog los ntawm kev ntxiv cov tshuab, tab sis los ntawm kev ua kom muaj kev txawj ntse ntawm metallurgical. Tam sim no, peb tau lees paub cov txheej txheem hybrid rau T800 alloy cov khoom: peev casting ua raws li kev xaiv laser melting ntawm hnav nto. Qhov no tsis yog R & D theatre. Nws daws qhov mob tiag tiag: cov neeg siv khoom xav tau cobalt-nickel ncej rollers nrog cov tawv tawv (HRC 58-62) tab sis cov ductile cores (≥35% elongation). Cov txheej txheem ib txwm xav tau tom qab nrum induction hardening-uas warps nyias-walled geometry. Peb cov kev daws teeb meem xa ob qho khoom hauv ib qho kev ua haujlwm, nrog rau tag nrho NDT validation ntawm txhua theem. Yog tias koj daim ntawv thov xav tau ob leeg heev corrosion kuj thiab Qhov cuam tshuam rau kev tiv thaiv-lossis yog tias koj tus neeg muag khoom tam sim no kho AMS 5387 "tsuas yog lwm yam stainless" - koj xav tau ib tus khub uas pom cov pwm tsis yog cov cuab yeej, tab sis raws li thawj txheej txheej txheej ntawm kev ua haujlwm. Qhov no yog li cas precision pib.
