Tshaj Tawm Daim Ntawv Qhia: Qhov Precision hauv Precision Casting
Cia peb tham txog lo lus ntawd, 'precision'. Hauv cov ntsiab lus ntawm lub tuam txhab xws li Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), uas lawv qhov chaw https://www.tsingtaocnc.com cov xeev muaj ntau tshaj 30 xyoo nyob rau hauv casting thiab machining, precision tsis yog ib qho kev thov zoo li qub. Nws yog lub peev xwm tsim los ntawm kev ua tsis tiav. Thaum ntxov hauv kuv qhov kev cuam tshuam nrog cov geometries nyuaj-xav tias nyias-walled aerospace brackets nrog ib qho kev ua kom txias-peb tau kawm tias kev ua tiav ± 0.005 nti kam rau ua tsis yog hais txog pwm xwb. Nws yog hais txog ambient humidity nyob rau hauv lub chav wax txhaj tshuaj hnub ua qauv. Ib hnub ntub txhais tau tias me ntsis softer ciab, uas txhais tau tias hloov maj mam distortion thaum lub plhaub tsev. Qhov 'precision' los ntawm kev tswj hwm huab cua, tsis yog los ntawm kev yuav khoom kim dua. Qhov no yog hom granular, kev ua haujlwm nthuav dav uas cais qhov tseeb peev thiab precision casting tus khub los ntawm ib lub chaw ua haujlwm. QSY tsom mus ntev rau plhaub molding thiab peev casting qhia tias lawv tau navigated tib lub microclimates ntawm cov txheej txheem tswj.
Lub synergy ntawm casting thiab machining yog lwm qhov chaw uas daim ntawv qhia zoo raws li lub grinder, lus. Koj tuaj yeem nrum qhov ze-net-shaped valve lub cev, tab sis yog tias koj tus khub machining tsis nkag siab txog cov qauv kev ntxhov siab lossis qhov muaj peev xwm rau me ntsis porosity hauv qab ntawm daim tawv nqaij nyob rau hauv ib cheeb tsam ntawm lub casting, thawj CNC hla yuav ua rau ib qho zoo kawg nkaus. Qhov tseeb tias QSY integrates CNC machining yog ib qho tseem ceeb qhia. Nws txhais tau hais tias lawv tswj tag nrho cov txiaj ntsig ntawm cov hlau molten mus rau qhov tiav tiav. Qhov no zam qhov kev thuam classic: tus kws kho tshuab hais tias qhov kev ua haujlwm tsis zoo, lub hauv paus hais tias lub tshuab ua haujlwm hnyav dhau. Thaum nws yog ib lub tsev, cov lus tawm tswv yim yog tam sim ntawd. Lawv kawm tias rau ib qho tshwj xeeb 17-4PH stainless hlau batch, lawv yuav tsum tau kho cov kev kho cua sov ua ntej machining los tiv thaiv cov cuab yeej hnav. Qhov ntawd yog qhov tseeb tiag.
Kev xaiv cov ntaub ntawv yog qhov chaw cov ntaub ntawv theoretical raws li lub qhov cub.

Nws yog hais txog kev nkag siab tias lawv cuam tshuam li cas nrog lub plhaub ceramic. Ib co ntawm cov alloys no incredibly reactive. Kuv nco qab txog qhov project rau qhov kub-kub nozzle qhov twg peb siv cov khoom siv cobalt alloy. Cov ntaub ntawv hais tias cov khoom siv plhaub taum tau txais. Lawv tsis yog. Peb tau txais cov tshuaj tiv thaiv tsis zoo, ib hom kev ntsuas uas coj microns tawm ntawm qhov kev kam rau siab. Qhov kho tsis yog fancier alloy; Nws yog qhov sib txawv thawj slurry formulation nrog ntau dua zirconia cov ntsiab lus. Ib lub tuam txhab nrog 30 xyoo ntawm cov ntaub ntawv keeb kwm, raws li tau hais hauv QSY's intro, yuav muaj ib lub tsev qiv ntawv ntawm cov kev sib raug zoo ntawm cov kev kawm no - tej zaum tsis muaj ntaub ntawv tab sis nqa hauv cov txheej txheem engineers lub taub hau.
Lub Plhaub Game: Nws yog Txhua Yam Txog Pwm
Plhaub molding, feem ntau hais nyob rau hauv tib lub pa raws li peev casting, yog tej zaum tsis meej pem nrog nws. Hauv kev nkag siab yooj yim, kev nqis peev casting siv cov qauv siv faus rau hauv ib puag ncig ntawm lub plhaub ceramic. Plhaub molding feem ntau yog siv cov resin-bonded xuab zeb pwm tsim nyob ib ncig ntawm cov qauv hlau. Qhov txawv ntawm qhov tshwm sim? Nto tiav thiab nthuav dav. Rau cov yam ntxwv zoo tshaj plaws-xav tias cov kaum ntse ntse ntawm cov cuab yeej phais lossis cov ntawv sau zoo ntawm lub iav-kev nqis peev casting yog huab tais. Tab sis lub plhaub txheej txheem yog incredibly robust rau loj, me ntsis intricate qhov chaw nyob rau hauv ntau dua ntim. Kev txawj ntse peev thiab precision casting txwv kev lag luam feem ntau masters ob leeg vim lawv ua hauj lwm sib txawv niches nyob rau hauv tib lub lag luam dav ntawm complex hlau qhov chaw. Nws yog hais txog kev haum cov txheej txheem rau ib feem ntawm kev ua haujlwm thiab kev lag luam, tsis yog yuam ib qho kev daws teeb meem.
Lub plhaub-tsev txheej txheem nyob rau hauv peev casting yog ib tug kos duab disguised raws li ib tug science. Lub dip, ntws, stucco, qhuav voj voog zoo li ncaj nraim. Tab sis tus naj npawb ntawm cov khaubncaws sab nraud povtseg, lub kaum sab xis ntawm cov kua dej, qhov loj me ntawm cov xuab zeb stucco rau txhua lub tsho tiv no - cov no yog txhua yam hloov pauv tau ntau xyoo. Ob peb txheej, thiab lub plhaub tawg thaum nchuav. Ntau dhau lawm, thiab koj nkim cov khoom siv thiab lub voj voog sij hawm, thiab tuaj yeem ua rau muaj teeb meem txias ua rau lub ntsws tsis xws luag. Lub hom phiaj yog lub plhaub yam tsawg kawg nkaus uas tuaj yeem tiv taus lub siab metallostatic thiab thermal shock. Kuv tau pom cov khw uas qhov no yog cov kev paub dawb huv ntawm pawg neeg, dhau los ntawm kev hloov pauv mus rau kev hloov pauv. Cov uas muaj kev vam meej, kuv xav tias zoo li QSY, tau tswj kom codify yam tsawg 80% ntawm nws mus rau hauv cov txheej txheem tswj tsis tau, thaum tawm hauv chav rau cov kws txawj kov ntawm cov hauj lwm nyuaj tshaj plaws.
Kev soj ntsuam tsis tiav los ntawm cov teeb meem ntsig txog lub plhaub yog ib tus kws qhia ntawv tas li. Ib qho classic: veining defects ntawm cam khwb cia saum npoo, zoo li tsa cov kab nyias. Nws zoo li cov teeb meem hlau, tab sis nws yuav luag ib txwm muaj teeb meem ntawm lub plhaub - thermal expansion mismatch lossis tawg hauv lub plhaub uas tau ntim nrog hlau. Cov tshuaj yuav yog kho qhov kub thiab txias ntawm lub plhaub los yog hloov cov khoom refractory nyob rau hauv lub prime tsho tiv no. Txhua qhov teeb meem zoo li no, daws tau thiab sau tseg, ntxiv rau lub tuam txhab cov khoom ntiag tug tiag tiag. Qhov no tsis yog patentable khoom; Nws yog qhov gritty, cov tswv yim paub-yuav ua li cas tso cai rau lub tuam txhab kom ntseeg tau tias lub impeller stainless hlau impeller yuav tsis cavitate los yog nickel-alloy tshav kub tiv thaiv bracket rau lub dav hlau cav.
