Iinkampani ze-Ductile iron casting factory-eli binzana alikho nje igama lokukhangela. Ziinjineli zokuqala zesihluzi kunye nabaphathi bokuthenga abafaka izicelo xa kufunwa iindawo ekufuneka zisinde kwi-300-bar hydraulic pulses, amashumi eminyaka okunxitywa kwe-abrasive, okanye ukukhwela ibhayisekile ngokushushu kwimpompo yokutyibilika elunxwemeni. Ukuchaneka akukhethi. Yakhelwe kumaqhuqhuva egraphite, yaqinisekiswa kuso sonke iskena seCMM, kwaye itshixiwe kunye nokulandeleka okupheleleyo kwezinto.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza enye into enjalo-ehambelana ne-ISO, idityaniswe ngokuthe nkqo, kwaye imiliselwe kwi-ecosystem yeshishini laseQingdao. Siye sabona abathengi bebuyela kathathu-kungekhona ngenxa yokuba imizobo yabo itshintshile, kodwa ngenxa yokuba iindlela zabo zokungaphumeleli zenza. I-piston pump cylinder yezindlu yaqhekeka kwiinyanga ze-18 kwisicelo se-North Sea multiphase. Unobangela weengcambu? I-Micro-shrinkage kufuphi ne-interface ye-flange ephathwe ukushisa. Olo hlengahlengiso-oluhlaziyiweyo lwe-gating, izinga lokupholisa elilawulwayo, i-post-cast stress i-post-cast i-post-cast stress ngaphambi komatshini-ngoku iinqanawa ezine-AMS 2750 ze-pyrometric logs kunye nemivalo edibeneyo evavanyiweyo kwi-ASTM A536 yeBanga 65-45-12. Amava okwenyani abumba ulawulo lwenkqubo yokwenyani.
Izakhono ezine zahlula umzi-mveliso othembekileyo we-ductile iron casting kubathengisi bempahla:
- Uqeqesho lwe-Metallurgical phezu kokutshintshwa kwezinto: Akukho kutshintshaniswa “kwibakala elilinganayo”. Yonke ibhetshi yentsimbi ye-ductile iqala ngezinto eziqinisekisiweyo zentlawulo-intsimbi yehagu, i-ferrosilicon, kunye ne-magnesium master alloys elandelwa yinombolo yeqashiso. Siqinisekisa i-nodularity (ASTM E2392), ukubalwa kwamaqhuqhuva (≥150/mm²), kunye nomlinganiselo we-ferrite/pearlite nge-metallography-hayi nje ukuqina kofundo. Xa i-OEM yaseYurophu ichaza i-ASTM A ye-winch ephezulu ye-winch ye-shaft roller, siye saqhuba ukushisa kwee-pilot ezimbini kunye ne-inoculation yokwahlukana ukubetha i-72 ksi isivuno ngaphandle kokucima.
- Ukuhlanganiswa komatshini wokuphosa njengomsonto omnye wobunjineli: Ukunyamezela kokuphoswa kwesanti akupheli emva kwe-CNC. Sisebenza ngomatshini iindawo zokutywina ezibalulekileyo *kwindlela enye* esetyenziselwa ukujika-jika-akukho kulungiswa kwakhona. Kwimizimba yevalvu yoxinzelelo, oko kuthetha ukuba ± 0.015 mm ukunyamezelana kwendawo phakathi kwamabhore ezibuko kunye nobuso be-actuator enyukayo, ebanjwe ngaphesheya kwe-5-axis milling kunye ne-OD yokusila. "Asongezi ngokuchanekileyo kamva." Siyilwa kwidrafti yokuphosa, indawo yoshicilelo engundoqo, kunye neskimu somatshini wedatha ukususela kusuku lokuqala.
- Ukuqinisekiswa okusebenzayo-hayi nje ukuthotyelwa komda: Isiseko sempompo asivunywanga emva kokuhlolwa kweCMM. Ibotshelelwe kwi-rig yokuvavanya, ilayishwe kwi-torque ye-1.5 × yokusebenza, kwaye iskenwe ukuphambuka nge-laser interferometry. Siye sabamba i-resonance harmonics kwi-212 Hz eyabangela ukukhathala ukuqhekeka kwiiyunithi zentsimi-kubonakala kuphela ngexesha lovavanyo lomthwalo oguqukayo, kungekhona ukuhlolwa kwe-static. Abathengi bafumana zombini iingxelo ze-GD&T *kunye* nezishwankathelo zovavanyo olusebenzayo.
- Unikezelo lwetsheyini elubala ungaphicotha: Iziqinisekiso zemathiriyeli ekrwada zifika ngaphambi kokuba zinyibilike. Iitshathi zonyango lobushushu zifakwe isitampu sexesha kwaye zisayinwe. Yonke iplagi ye-cobalt-nickel eyenziwe kwi-T800 alloy iphethe ingxelo ye-PMI ehambelana nesiqinisekiso sayo se-AMS 5387. Akukho "ziqinisekiso zomthengisi." Ubungqina obubhaliweyo nje-obulandelekayo kwi-ID yesithando somlilo, ukutshintshwa kwabaqhubi, kunye nesatifikethi sokulinganisa i-spectrometer esetyenzisiweyo.
Abanye bayaxoxa ukuba ukuphoswa kwesanti akukwazi ukuhambelana nokuphosa utyalo-mali kwiijometri ezinzima. Kodwa siye sathumela i-AMS 5387 i-cobalt alloy nozzles kunye ne-0.8 mm yodonga lwamacandelo kunye neziteshi zokupholisa zangaphakathi-ezifakwe kwintlabathi eluhlaza, emva koko zenziwe ngezixhobo zedayimane ze-polycrystalline. Ngoba? Ngenxa yokuba ivenkile yethu yepateni isebenzisa i-SLA-printed resin molds kunye ne-ceramic shell backing, kunye neqela lethu le-Foundry lihlengahlengisa uxinzelelo lwe-compaction ngexesha langempela ngokusekelwe kwi-sensors ze-santi zokufuma-kungekhona ukusetwa kwe-thumb. Ukuntsonkotha akuphetshwa. Ilawulwa ngolawulo olunemaleko.
Iindleko zihlala zibuzwa. Nantsi into ehambisa inaliti: inxalenye yokunciphisa ubunzima iyancipha iindleko zempahla ekrwada kodwa inyusa ixesha lomatshini; i-GD & T eqinile iphakamisa umsebenzi wokuhlola kodwa iphelisa ukusilela kwintsimi; i-dual-certified ductile iron (ASTM A536 + ISO 1083) yongeza i-$ 1.20 / kg kodwa igwema ukuphinda usebenze kwii-oda zokuthumela ngaphandle. Sicaphula zonke iinketho ezintathu-kunye nohlalutyo lwendlela yokungaphumeleli nganye. Omnye umthengi waseMzantsi-mpuma Asia uye watshintsha ukusuka kwizindlu zentsimbi ezirhweba kwamanye amazwe ukuya kwimveliso yethu yasekhaya emva kokubala iindleko zizonke zobunini: ngama-22% ngaphantsi kwiminyaka emihlanu, kubandakanywa nokulungiselela, intlawulo, kunye nexesha lokuphumla elingacwangciswanga ekuhanjisweni kade.
Iinkampani ezithembekileyo ze-ductile iron casting factory azithembisi ukugqibelela. Bathembisa ukuxela kwangaphambili. Kwi-QINGDAO QIANGSENYUAN TECHNOLOGY, oko kuthetha ukuba yonke ivalve yoxinzelelo inenombolo eyodwa yesiriyali edityaniswe nelogi yayo yokunyibilika, uhlaziyo lwenkqubo yomatshini, kunye nerekhodi yokugqibela ye-hydrotest. Kuthetha ukuba ixesha lokukhokela iprototype ziintsuku ezili-18-hayi "kamsinyane." Kuthetha ukuba injineli yakho ifumana uphononongo lokwenziwa kwezinto ngaphakathi kweeyure ezingama-48 zokulayisha-hayi uluhlu lokukhangela lwe-PDF.
Ikamva alikho iziko likhulu. Kukudityaniswa okuhlakaniphileyo: ukucinga ngexesha langempela lobushushu ngexesha lokuqina, ukubikezelwa kwe-porosity encediswa yi-AI ukusuka kwi-CT scans, iinkqubo ezixubileyo apho iziteshi zokupholisa eziphosiweyo zisusa iipaseji ezithunyelwe ngasemva. Kodwa akukho nanye kuloo nto ibalulekileyo ukuba isiseko sesinyithi siyakhukuliseka-okanye ukuba uzinzo lwe-dimensional lusilela kwi-60 ° C yobushushu bokusebenza. Yiyo loo nto sisajonga ngesandla ukuhanjiswa kwenodule yegraphite phantsi kwe-100× yokukhulisa. Ukuchaneka kuqala apho iliso liyeka-kwaye liphela apho isicelo sifuna khona.
