Masikhulume iqiniso, lapho abantu abaningi bezwa 'imvula iqinisa insimbi engagqwali', bacabanga ngeqhawe lemininingwane - 17-4PH, mhlawumbe 15-5PH, ngalezo zinombolo zamandla esivuno esihle. Iqiniso esitezi sesitolo, ikakhulukazi kuma-complex complex and machined components, isilwane esihlukile. Akukhona nje ngokushaya inombolo yokuqina; kumayelana nokuphatha umdanso phakathi kokwelashwa kwesixazululo, umjikelezo wokuguga, kanye nokuhlanekezela okungenakugwenywa okuza nakho, sonke kuyilapho ingxenye ivame ukuba ukufakwa kokutshalwa kwezimali okuyinkimbinkimbi, okunezindonga ezincane. Kulapho ulwazi lwangempela, nezihibe ezivamile, kuhlala khona.
Ukuheha kanye Nangempela KwamaBanga e-PH
Sithola imibuzo eminingi ye-17-4PH. Yindawo yokuya. Amaklayenti abona i-1300 MPa eqinile futhi acabange ukuthi iwukumiselela kunoma yisiphi isidingo samandla aphezulu. Kodwa ngike ngabona ama-projects ephuma ngaphandle kwesango ngoba abazange bacabangele isimo. Ingabe siqala nge-bar stock, i-forging, noma i-casting? Enkampanini efana neyethu, I-Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), lapho ukutshala imali kuyinqubo ewumongo, indaba iqala ngekhemistri encibilikayo kanye nesimo se-as-cast. I-homogeneity yesisombululo esimisiwe ngaphambi kokuba sicabange ngokuguga ibalulekile. Ukulingisa kungase kube nokuhlukaniswa okuncane okungenayo ibha esetshenzisiwe, okungaholela ekuphenduleni okungahambisani kamuva.
Bese kuba nokulandelana komshini. Ingabe umshini usesimweni sokwelashwa ngesixazululo (uthambile, ulula kumathuluzi) bese uyaguga? Noma ingabe uyaguga kuqala bese uzama ukufaka umshini impahla engu-40+ HRC? Eyangaphambili ivamise ukukhalipha, kodwa kufanele ubhake ekushintsheni kobukhulu ukusuka ekugugeni uye ekubekezeleni kwakho. Lokhu sikufunde kabuhlungu kusenesikhathi ngomzimba we-valve. Yakhiwe kahle ku-Condition A, yaguga, futhi yathola ukuthi ama-diameter abalulekile ayeqiniswe ngaphezu kokucaciswa. Kudingeke ukuba kulungiswe kabusha isixazululo kuphathe yonke indawo kanye nomshini kabusha, okuyisifundo esibiza kakhulu ekushayeleni ibhayisikili elishisayo.
Kukuphoqa ukuthi ucabange ngokuphelele. Ukuzikhethela akuyona nje insimbi engagqwali, kuwuchungechunge lwezinqubo: ubuqotho bokusakaza -> ukufana kwesixazululo se-anneal -> isibonelelo sesitoko sangaphambi komshini -> ukuguga okulawulwayo -> ukuqedwa kokugcina. Ukushoda kwesixhumanisi kunqamula iketango. Kungakho ezingxenyeni zangempela ezinokwethenjelwa okuphezulu, sivame ukusebenzisana nethimba lonjiniyela leklayenti kusukela esigabeni se-CAD, hhayi nje lapho i-RFQ ifika.
Isimo H900 vs. H1150: Akulona Nje Izinga Lokushisa
Izilinganiso zokuguga ezijwayelekile (H900, H1025, H1150) zingamaphuzu okuqala, hhayi ivangeli. I-H900 ikunikeza amandla aphezulu kodwa ukuqina okuphansi. Engxenyeni yegiye lokufika esisebenze kuyo, i-spec ibize i-H900. Kepha ngesikhathi se-prototyping, izivivinyo ze-Charpy ezingeni lokushisa eliphansi zazisemngceleni. Sibe nengxoxo ende ne-metallurgist yeklayenti. Singakwazi ukukhokhela idiphu yamandla kancane ukuze kube nokuqina okungcono kokuphuka? Sasebenzisa iqoqo ku-H925 bese kuba ngu-H950, sihlola ukushuba nomthelela. I-H950 isinike ibhalansi efanele - amandla ayesengaphezulu kakhulu kwenani elilinganiselwe lokuklama, kodwa amanani omthelela eqa. Yagunyazwa njengolunye umjikelezo wokuguga. I-database ayizange isitshele lokho; ukuhlolwa okulawulwayo kanye nokwahlulela kobunjiniyela kwenza.
Lapha yilapho iminyaka engu-30-plus ekulingiseni futhi CNC imishini kuyakhokha. Uthuthukisa umuzwa wokuthi impahla ihamba kanjani. Ukuqina kwemvula ama-alloys, ngesikhathi sokuguga, musa nje ukuba nzima; babhekana noshintsho olucashile lobukhulu. Ngendlu eyinkimbinkimbi, engalingani kahle yokutshala imali, lokhu akufani. Sesiqalile ukusebenzisa amakhuphoni okuhlola omhlatshelo afakwe endaweni efanayo, enamathiselwe ezindaweni ezibucayi zengxenye ngamasango amancane. Siguga yonke inhlangano, bese sisika amakhuphoni ukuze sihlole ubulukhuni nobukhulu. Isinyathelo esengeziwe, kodwa sibonisa impendulo yokuguga kuyo yonke ingxenye yejometri, konga usizi kamuva.
Ake sikhulume ngokusebenza kabusha. Kuthiwani uma ingxenye isikhulile bese idinga ukukhanda insimbi? Kuyiphupho elibi. Ukushisa okuvela ekushiseleni kudala i-HAZ, kudala indawo ethambile. Ngokuvamile kufanele ubuyele emuva ku-anneal yesisombululo esigcwele, engasonta ingxenye, bese umshini kabusha futhi uguge kabusha. Ngezinye izikhathi, ukonga kakhulu ukuyichitha. Leli yiphuzu eliyisihluthulelo esiligcizelelayo phakathi nokubuyekezwa komklamo QSY: uma ukushisela kuyinto engenzeka esikhathini esizayo, mhlawumbe ibanga elihlukile le insimbi engagqwali kungcono, ngisho noma amandla okuqala ephansi. Ingqikithi yezindleko zomjikelezo wempilo ibalulekile.
I-Special Alloys Overlap: PH vs. Maraging
Lena i-tangent ethokozisayo. Siphinde sisebenze ama-alloys akhethekile njengezinsimbi zokudoba. Amakhasimende kwesinye isikhathi awadidanisa ne-PH engenabala. Zombili ziqina ngemvula, kodwa izinsimbi ze-maraging ziyi-iron-nickel ene-cobalt, i-molybdenum, i-titanium - ayikho i-chromium yokumelana nokugqwala. Bayisilwane esihlukile. Ukwelashwa kwesixazululo sabo kuyi-austenitize elula futhi epholile emoyeni, eyenza i-martensite ethambile. Ukuguga bese kudlula ama-intermetallics. Ukuhlanekezela ngokuvamile kuphansi kune-PH engenasici, okuyinzuzo enkulu yezingxenye ezinde, ezacile zomshini.
Ngikhumbula iphrojekthi yeshafti ye-actuator enembayo ephezulu. Ukudlula kokuqala kwaba ne-15-5PH. Ngemva kokuguga, ubuqotho babuphumile. Siphinde sayiqondisa ngokucindezela ngokunemba, kodwa ayilungile. Siphakamise insimbi ye-maraging ye-C250 njengenye indlela. Ukumelana nokugqwala bekungadingeki (bekusendaweni evalekile, egcotshiwe). Umzila wokuzulazula usinike amandla, ukwelapha ukushisa okulula okunokuhlanekezela okuncane, kanye nobuciko obuhle kakhulu esimweni esifakwe isixazululo. Bekulingana kangcono. Kumayelana nokuba nephalethi yezinto kanye nolwazi lokwazi ukuthi kufanele uphume nini ngaphandle kwebhokisi elingenabala elijwayelekile.
Lolu hlobo lokudlulisa impova kolwazi lubalulekile. Ukusebenza nge ama-alloys asekelwe ku-nickel nama-alloys e-cobalt akufundisa okuningi mayelana ne-kinetics yemvula kanye nokuzwela kokwelashwa kokushisa. Lolo lwazi lubuyela emuva endleleni esiphatha ngayo amabanga e-PH avame kakhulu. Konke kuxhunyiwe.
CNC Machining: The Tooling kanye Coolant Dance
Ukulungisa i-PH ngaphandle kwebala, ikakhulukazi esimweni sobudala, yilapho ushisa khona ngokusebenzisa ibhajethi yamathuluzi uma unganakile. Iyahlukumeza futhi iqinisa umsebenzi. Sixazulule ngemithetho embalwa eqinile. Okokuqala, ukusetha okuqinile. Noma iyiphi ingxoxo izosebenza ngokushesha-yenza lukhuni indawo, yenze okulandelayo kudlule isihogo. Okwesibili, ukufakwa kwe-ceramic noma okuthuthukisiwe kwe-carbide ngamajiyometri abukhali, aqondile. Asisebenzisi insimbi enesivinini esikhulu lapha. Isipholile asixoxiswana ngaso, futhi kufanele sibe ukuthambisa okuphezulu, uhlobo lokwenziwa, olugcwele izikhukhula. Umgomo uwukukhipha ukushisa nge-chip, ungakuvumeli ukuthi kucwiliswe engxenyeni futhi ngokunokwenzeka endaweni kuguge kakhulu.
Ukubhoboza imigodi ejulile kuyinselelo ethile. I-Peck drilling iyadingeka, ngokuhlehla okugcwele ukuze usule ama-chips kanye nokupholisa amanzi phansi komtshingo. Samosha ama-casting ambalwa abizayo kusenesikhathi ngokuvumela ama-chips aqhume inyongo futhi ashisele endaweni yokubhoboza, eyabe isiphuma emgodini. Manje, izinhlelo zethu ze-CNC zalezi zinto zokusetshenziswa zinamathebula okuphakelayo/isivinini, akhiwe kusukela eminyakeni yokuzama namaphutha. Imininingwane ekuwebhusayithi yabo, https://www.tsingtaocnc.com, ikhuluma ngamakhono, kodwa amandla angempela yilabhulali yepharamitha kuzilawuli zethu zomshini kanye nolwazi lwabahleli bethu bezinhlelo abazi ukuthi bangayibhala nini ngaphezulu.
Ukuqedwa kobuso nakho kubalulekile. Indawo esebenza kanzima ku-PH ingxubevange ingaba indawo yokugxilisa ingcindezi kanye nesayithi lokuqalisa ukugqwala. Sivamise ukucacisa iphasi lokugcina elinokufakwa okuphothulayo okuzinikele noma ngisho nokusebenza okulula kokugaya/ukupholisha ezindaweni zokuvala. Yengeza izindleko, kodwa ngokwengxenye endaweni ebolayo, enengcindezi enkulu, umshwalense.
Ukubheka Emuva Nokuya Phambili
Pho, lokhu kusishiya kuphi imvula iqinisa insimbi engagqwali? Umndeni omuhle wezinto zokwakha, kepha udinga ukuhlonishwa kanye nendlela yezinhlelo. Akuyona impahla. Inani elilethwa umphakeli akukhona nje ekuncibilikeni nasekuthululeni noma ekusebenziseni umshini we-CNC; kusekuhlanganiseni lezo zinyathelo ne-metallurgy.
Ngo QSY, eminyakeni engamashumi amathathu edlule ukubunjwa kwegobolondo, ukutshala izimali, nokwenza imishini kusho ukuthi sizibonile lezi zinkinga ngaphambilini. Sisonte izingxenye, amathuluzi aphukile, futhi sathumela amakhuphoni okuhlola ukuze silungise ijika eliguga kahle. Leyo nkumbulo yesikhungo yiyona evimbela lezo zinkinga ukuthi zingaphinde zivele kuphrojekthi elandelayo. Kusivumela ukuthi siqondise amakhasimende kude nezingibe ezingaba khona - njengokucacisa ukuguga kwe-H900 kokusakaza okukhulu, okunengxenye encane okuzohlanekezela ngokungalawuleki, noma ukuhlela isinyathelo sokushisela ngemva kokwelashwa kokushisa kokugcina.
Ikusasa, ngicabanga, lisekuhlanganiseni okuqinile. Mhlawumbe ukusebenzisa ukulingisa ukubikezela ukuhlanekezela ukuguga okusekelwe ku-casting geometry, noma ukusetshenziswa okusabalele okwengeziwe kokuqapha okungaphakathi kwenqubo phakathi nomshini ukuze kutholwe ukuguga kwamathuluzi ngaphambi kokuthi kuthinte ubuqotho bomhlaba. Kodwa umongo uzohlala: ukuqonda ukuthi i-PH ingenasici iyinqubo, hhayi nje into. Awuthengi insimbi; uthenga ukukhishwa okuyimpumelelo kokulandelana kwe-thermal nemishini. Futhi ukuthola lokho kulandelana kahle yilokho okuhlukanisa ingxenye esebenzayo kwethembekile.
