Xa iinjineli zichaza umgubo wemveliso yesinyithi somgubo wezinto ezibaluleke kakhulu kwimishini, ayiyonto nje yokukhangela iindawo-zikhusela uzinzo lwe-dimensional under 300 MPa hydraulic loads, microstructural consistency ku-500-unit batches, kunye nokuthembeka komsebenzi apho ukusilela kuthetha ukwehla okanye umngcipheko wokhuseleko. Yiyo loo nto amashishini aqhutywa ngokuchanekileyo-ukusuka kwimpompo yoxinzelelo oluphezulu lwe-OEMs eJamani ukuya kwizihlanganisi zezixhobo ze-oyile eTexas-enyuka ngokudlula ababoneleli begeneric kwaye abandakanye iingcali eziphatha i-alloy chemistry, iifestile zonyango lobushushu, kunye nokunyamezela kwe-GD&T njengamagalelo angaxoxisiyo-hayi emva kokucinga.
Kutheni i-Metallurgy yePowder ingeyiyo nje "uthuli lwesinyithi + nobushushu"
I-Metallurgy ye-Powder (PM) ihambisa ukuntsonkotha kwe-net-shape, inxinano ekufutshane-yethiyori, kunye ne-porosity elawulwayo-kodwa kuphela xa lonke ikhonkco lenziwe ngobunjineli: isatifikethi sezinto eziluhlaza, uyilo lwezixhobo zokushicilela, ulawulo lwe-sintering atmosphere, kunye neqhinga le-post-sinter machining. Uninzi olubizwa ngokuba "ziifektri ze-PM" ezikhupha ngaphandle okanye zixhomekeke kwi-powderstock feedstock ngaphandle kweshelufu. Oko kudala ukungafani kwisakhiwo sokutya okuziinkozo, ukusabalalisa uxinzelelo olushiyekileyo, kunye nobomi bokukhathala-ingakumbi kwii-alloys ze-cobalt-nickel ezifana ne-AMS 5387 okanye i-T800-grade materials. Siye sabona abathengi besala i-12% yebhetshi emva kovavanyo lwe-ultrasonic kuba amaxabiso erempu e-sintering ahluka nge-± 5 ° C kwiindawo zomlilo. Impumelelo ye-PM yelizwe lokwenyani iqala ngokudityaniswa ngokuthe nkqo: ukuphosa, ukusetyenzwa kwe-CNC, kunye nokugqiba phantsi kophahla olunye, kunye nemigangatho ekwabelwana ngayo ye-metrology kunye neelog zenkqubo ezinokulandeleka.
Izakhono ezine ezahlula iifektri zePM eziSebenza ngokuPhezulu
Ayizizo zonke iiseti zefektri zabenzi bemetalurgy ezizisa iziphumo ezilinganayo. Ngokusekwe kuma-200+ ophononongo lobuchwephesha kunye nabayili benkqubo yehydraulic kunye neenjineli zendibano yempompo, ezi zakhono zine zihlala ziqikelela ukuhanjiswa kwexesha kwamalungu asebenzayo:
- Ulawulo lwemfuyo eqinisekisiweyo ngezinto eziphathekayo: Umgubo okrwada ufunyenwe kuphela kwi-ISO 9001/ISO 14001-eqinisekisiweyo yokusila-kunye ne-Co, Ni, Cr, Mo, kunye nomxholo we-C oqinisekisiweyo nge-ASTM E3061 ngaphambi kokudibanisa
- Kwinkqubo ukuqinisekiswa komlinganiselo: I-CMM engaphakathi ijonga kwinqanaba eliluhlaza, elimdaka, kunye ne-sintered-hayi nje uhlolo lokugqibela-ukubamba isixhobo sokunxiba ngaphambi kokuba sichaphazele ubukhulu bodonga lwe-0.02 mm
- Ubuchule benkqubo yeHybrid: Isandla esingenamthungo phakathi kwe-PM kufutshane ne-net-net shape kunye ne-multi-axis CNC machining kwiimpawu ezifana neetaper zesihlalo sevalve yangaphakathi okanye i-asymmetric winch shaft splines ezithi ukuntywila kukodwa kungabinako ukusombulula.
- Ulungelelwaniso lovavanyo olusebenzayo: Zonke izindlu zevalve yoxinzelelo zivavanywa kwi-1.5 × uxinzelelo lokusebenza; yonke imilomo ye-cobalt yengxubevange ihamba-ikhangelwe ngokuchasene ne-API RP 14E imifuziselo yokhukuliseko-hayi nje ukupasa okulinganayo/ukusilela
Eyona nto ifunwa ziinjineli-kunye nento abadla ngokungayihoyi
"Ungayenza le nxalenye?" ngumbuzo wokuqala ongalunganga. Abafanelekileyo ngaba: "Yintoni inqanaba lakho le-sintering shrink ye-AMS 5387 kwi-1220 ° C kwi-H₂ / N₂? Ngaba uqinisekisa ubuninzi obuluhlaza ngaphambi kokucinezela? Abanye abavelisi bacaphula unyamezelo oluqinileyo kodwa abanalo ixesha lokwenyani lokujonga ukuxinana kohlaza-ke iinxalenye zijika ngokungalindelekanga ngexesha lokutshiza. Abanye oomatshini bokucoca indawo ngaphandle kokuthomalalisa uxinezeleko kuqala, bazisa iintanda ezincinci ezisasaza phantsi kokulayisha umjikelo. Kwi-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., yonke i-cobalt alloy component idlula kwisisombululo se-annealing kwi-1180 ° C ± 3 ° C ngaphambi kokugqiba umatshini-iqinisekiswe ngeengxelo ze-metallography ezibandakanyiweyo kunye nokuthunyelwa ngalunye. Ayizondleko ezongezelelweyo ezo. Yindlela okhusela ngayo ukusilela kwintsimi kwiindibano zempompo zaphesheya.
Ukukhetha iqabane, hayi umthengisi
Umzi-mveliso ovelisa isinyithi somgubo kufuneka usebenze njengolwandiso lweqela lobunjineli bakho—hayi ibhokisi emnyama. Jonga imijikelo yokuphononongwa kwe-GD&T ebhaliweyo, ukulandeleka kwemathiriyeli ukuya kwindawo yobushushu kunye ne-ID ye-log yesithando somlilo, kunye nokuvuma ukuhlanganisana nokuphuhlisa iiparamitha zenkqubo yeejiyometri ezingekho mgangathweni. Xa i-OEM yepompo yaseYurophu idinga i-piston pump cylinder yezindlu kunye neziteshi zokupholisa ezihlanganisiweyo, siye saqhuba izilingo ezintathu ze-sintering kunye neeprofayili zokutshiswa kwe-binder-kwaye sabelane ngedatha ye-imaging ye-thermal kwi-run nganye. Oko kungafihlwa kunqumle ixesha labo lemfundo ngama-40%. Awudingi owona mzi-mveliso mkhulu. Udinga lowo uphatha umzobo wakho njengesivumelwano-hayi ingcebiso.
Kwizicelo ezinyanzelisayo kwiinkqubo zamanzi, izixhobo ze-oyile negesi, kunye neenqwelo zombane zemoto yobunjineli, ukhetho lwemizi-mveliso yomgubo wesinyithi olungumgubo luxhomekeke kuqeqesho lwenkqubo enokuqinisekiswa—hayi amabango encwadana. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza kwiziko elithobelayo le-ISO eQingdao apho amacandelo e-cobalt-nickel alloy aphantsi kolawulo lomjikelo ogcweleyo: ukuthathwa kwempahla ekrwada eqinisekisiweyo, i-sintering nge-real-time monitoring atmosphere, i-CNC machining nge-in-process CMM verification, kunye novavanyo olusebenzayo oluhambelana neemeko zokusetyenziswa kokuphela. Ugxininiso lwabo luhlala lumxinwa-izinto ezichanekileyo zemizi-mveliso ezakhelwe ukwenza-hayi izithembiso zokuthengisa ezibanzi. Olo gxininiso luzisa iindawo ezibambekayo xa uxinzelelo lunyuka, i-spikes yobushushu, kunye neyona nto ibalulekileyo yexesha.
