Iyo abajenjeri bagaragaje ibikoresho bya pompe hydraulic, drives ya winch, cyangwa moteri yumuvuduko ukabije wa valve, ntibakunze gutangirana nifu ya metallurgie. Benshi bagera kubanza ibyuma byahimbwe cyangwa CNC yakozwe na mashini-kugeza igihe ihagaze neza, kwambara, hamwe nigiciro cyose kuri buri gice gitangira guhindura ibara. Aho niho abiyeguriye ifu ya metallurgie ibikoresho byuruganda ihagarike kuba ubundi - kandi ihinduka ihitamo ryonyine.
Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Twabonye iri hinduka imbona nkubone imigabane itatu. Amapompo yo muri Amerika ya ruguru OEM yagabanije inshuro 40% yo gusimbuza ibikoresho nyuma yo kuva mucyuma cyacumuye akajya muri AMS 5387 cobalt alloy PM ibikoresho byamazu ya pompe ya piston. Isosiyete ikora ibinyabiziga byubwubatsi byu Burayi yagabanyije igihe cyiminsi 11 - ntabwo yihutishije imashini, ahubwo ikuraho ibikorwa bitanu byanyuma. Ibi ntabwo byari inyungu zifatika. Bavuye mu kugenzura imiyoboro ihanitse muri ± 0,02 g / cm³, bafashe kwihanganira diameter ya metero 0,015 mm kuri 16-module ya spur, no kugera ku bushyuhe bwa Ra ≤ 0.8 µm—nkicyaha.
Ubusobanuro nyabwo muri powder metallurgie ntabwo ari ugukanda umukungugu wibyuma no kubyita byakozwe. Itangirana no kwemeza ibikoresho fatizo: buri cyiciro cya T800 cobalt ishingiye kuri poro itwara ibisobanuro byuzuye kubipimo bya atome, ibirimo ogisijeni (≤120 ppm), hamwe no gukwirakwiza ingano (D50 = 18-22 µm). Twanze ifu hanze yiryo dirishya-niyo uwatanze isoko yagabanutseho 15%. Kubera iki? Kuberako 0,3% ihindagurika ryumuzi wibikoresho bitera igabanuka rya 22% mubuzima bwunaniza ubuzima munsi yumuzigo. Twemeza ko burimunsi dukoresheje ihame rya Archimedes hamwe na micro-CT gusikana kuri sample yibanze - atari kubice byanyuma gusa, ariko kubicyatsi, icyatsi, nicyiciro.
Igicuruzwa cyacu gihuza imbaraga eshatu zidashobora kuganirwaho amaduka menshi ya PM afata nka serivisi zitandukanye:
- Kugenzura ikirere hamwe no gucunga neza ikime (−40 ° C kugeza kuri ° 25 ° C) hamwe na azote / hydrogène ivanze-ni ingenzi mu gukomeza gukwirakwiza karbide mu mavuta ya cobalt nta decarburisation
- Igiceri Byakoreshejwe mugihe cyo gusohora, ntabwo ari nyuma yinyuma, gutanga ± 0.008 mm igenzura ryimikorere kubikoresho byuma bitarinze kwisubiraho
- Kuvura ubushyuhe bukora kwinjizwa mu buryo butaziguye nyuma yo gucumura: gukemura ikibazo kuri 1180 ° C + kuzimya byihuse kuri AMS 5387, bigakurikirwa no gusaza kuri 845 ° C - kugera kuri Rockwell C 42-46 mugihe urinze amenyo ya geometrie.
Bamwe bashobora kuvuga ko ibikoresho bya CNC bikoresha ibikoresho bitanga hejuru yo hejuru. Nukuri - kuri geometrike yoroshye. Ariko iyo umukiriya asabye amenyo 22, ibikoresho bya moderi ya 3.5-module ifite inguni ya 25 ° helix, umugongo w'imbere, hamwe na bore ikwiye-ikozwe mu kabari ka T800 - imibare ihinduka. Umusaruro wibikoresho wagabanutse kugera kuri 38%. Igihe cyinzira kirenga iminota 92. Igikoresho cyo kwambara imitwe nyuma yibice 17. Gahunda yacu ya PM itanga ibikoresho bimwe murwego rumwe rukomatanya, hamwe no gukoresha ibikoresho 91%, umwanya wiminota 14, nigihe cyo gukoresha ibikoresho bya zeru hagati yicyiciro. Ibikoresho bihura na AGMA Q12 na ISO 1328-1 Icyiciro cya 7 - nta gusya.
Ntabwo dusunika ifu metallurgie aho itari. Niba porogaramu yawe isaba ibikoresho byo gusubiza inyuma kurenza 0,02 mm mubushyuhe bwo gukora, cyangwa niba imitwaro yawe yikuramo irimo impanuka ya puls irenze 3 × yagabanijwe, tuzakubwira imbere: impimbano + kurangiza-inzira iracyari inzira yawe nziza. Ariko kubijwi rito (500-10,000 pcs / mwaka), ibidukikije byambara cyane (stress200 MPa itumanaho), cyangwa sisitemu aho uburemere, urusaku, cyangwa ibintu bitoroshye - PM itanga ROI yapimwe. Umwe mu bakora ibikoresho bya peteroli yo mu majyepfo y’iburasirazuba bwa Aziya yasimbuye ibikoresho 12 byo gusudira hamwe n’inteko imwe ya PM. Ibiro byagabanutseho 37%. Imirimo yo guterana yagabanutse kuva ku minota 4 igera kuri 9. Kandi amplitude yo kunyeganyega kuri 1800 rpm yagabanutseho 63% - bipimirwa kurubuga hamwe na laser Doppler vibrometry.
Niki gitandukanya abishoboye ifu ya metallurgie ibikoresho byuruganda kuva mububiko bwibicuruzwa ntibishobora-ni isesengura ryihariye ryo kunanirwa. Iyo ibikoresho byabakiriya byananiye imburagihe muri pompe yo mumazi, ntitwabisimbuye gusa. Twatandukanije igice cyananiranye, dushushanya amakarito ya porosity arwanya imihangayiko, duhuza okiside ihujwe n’ibiti byo mu kirere, hanyuma dusubiramo uburyo bwo gupfira mu cyuho. Igisubizo: gutsindwa kwa zeru mumezi 18 namasaha 47.000 yo gukora.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ikorera muri Qingdao-ntabwo nkibikorwa rusange-bigamije gushinga, ariko nkumufatanyabikorwa wibintu bya sisitemu aho ibikoresho bitagenda gusa. Nibintu byo gukumira igitutu. Imiyoboro ya Torque. Umunaniro-unanirwa. Turabashiraho muri ubwo buryo - kuva guhitamo ifu binyuze mukwemeza imikorere. Ikigo cyacu gifite impamyabumenyi ya ISO 9001: 2015 na AS9100D, ariko icy'ingenzi ni uburyo tubishyira mu bikorwa: buri bikoresho byoherejwe hamwe na raporo yuzuye yuzuye, ibiti byimbitse, imyirondoro ikomeye ku menyo yinyo no mu mizi, hamwe na micrografi ya metallurgie yibice bikomeye.
Ejo hazaza h'ibikoresho bisobanutse neza ntabwo bihitamo hagati ya PM na mashini. Nukubahuza mubwenge-ukoresheje PM hafi ya net geometrie hamwe nuburinganire bwimiterere, hanyuma ugashyiraho bike, bigamije CNC kurangiza gusa aho isura yimikorere ibisaba. Ubwo buryo bwa Hybrid-guteranya-gutunganya imashini-niho twibanda kuri R&D ubu. Ntabwo ari ugusimbuza inzira, ahubwo ni ugukuraho ubwumvikane.
