Uma abantu abaningi bezwa 'izingxenye zomshini,' bafanekisa umdwebo we-CAD noma ingxenye ecwebezelayo kukhathalogi. Leyo yinguqulo ehlanzekile. Iqiniso, lelo elikugcina ungalali ebusuku, limayelana noshintsho olusuka kuleyo modeli yedijithali ukuya engxenyeni ebonakalayo esebenza ngempela ngaphansi komthwalo, ukushisa, nengcindezi. Igebe phakathi komdwebo kanye nengxenye esebenzayo yilapho imboni yangempela ihlala khona-futhi lapho kulahleka khona imali eningi ngokucatshangwayo.
I-Illusion of Interchangeability
Enye yemibono eyiphutha enkulu ukuthi ingxenye iyisethi yobukhulu. Ungaba nambili izingxenye zomshini kubahlinzeki abahlukene abakala ngokufana ku-CMM, nokho oyedwa uyahluleka ngamaviki kanti omunye uhlala iminyaka. Umehluko awukho ku-geometry; kusekugelezeni okusanhlamvu kwe-forging, ijika lokwelapha ukushisa, noma ingcindezi eyinsalela evela kumishini. Ngike ngabona inqwaba yamashafu epompo adlula kuwo wonke amasheke obude kodwa anqamuke ngenxa yokuthi izitifiketi zezinto ezibonakalayo zazenziwa—insimbi ibinokuqina okungalungile. Ukuphrinta akuzange kucacise indlela ye-metallurgical, kuphela ubulukhuni bokugcina. Leso kwakuyisifundo sika-$200k.
Yilapho okusemuva kwe-Foundry kanye nemishini kuba okungaxoxiswana khona. Awukwazi ukuvele ukhiphele umbhidi oshibhe kakhulu ngomshini we-CNC. Inqubo iyingxenye yomkhiqizo. Ngokwesibonelo, at I-Qingdao Qiangsenyuan Technology (QSY), kanye neminyaka yabo engamashumi amathathu ekubumbeni nasekukhiqizeni, bazokutshela ukuthi isikhunta segobolondo somzimba we-valve sizoba nobuqotho obuhlukile obungaphezulu kanye nesimo esiseduze nenethi uma kuqhathaniswa nokubunjwa kwesihlabathi, ngisho nakwibanga elifanayo lensimbi engagqwali. Lokho kuthinta indlela oziklama ngayo izinyathelo zokwenza imishini ye-CNC elandelayo—izindlela zakho zamathuluzi, izindawo zakho zokubopha. Uma uwumshini njengokungathi yi-billet, wethula ukugxila kwengcindezi abachithe iminyaka engu-30 befunda ukukugwema.
Kukuphoqa ukuthi ucabange emuva. Uqala ngemodi yokwehluleka. Ingabe ukukhathala? Gqoka? Ukugqwala? Bese ubuyela emuva ezintweni kanye nenqubo yokukhiqiza. Ingxenye yolayini wokucubungula ukudla owenziwe nge-316L okungenasici akukhona nje ukumelana nokugqwala; imayelana nendlela izingxenye zomshini sebeqedile. Ukupholisha kwesibuko kungase kubukeke kukuhle, kodwa ingabe kudala imifantu emincane egcina amagciwane? Kwesinye isikhathi ukuqina okulawulwayo, okufana okufanayo okuvela kuphasi lomshini othile kungcono. Ishidi lokucaciswa ngeke likutshele lokho.
Okubalulekile kuyinqubo, Hhayi Ukukhetha
Ukukhetha insimbi engagqwali noma ingxubevange esekelwe ku-nickel kumenyu eyehlayo kuyisiqalo sengxoxo, hhayi isiphetho. Thatha Inconel 718. Izakhiwo ezinhle. Kepha ukuthi isakazwa kanjani uma iqhathaniswa nendlela eyakhiwe ngayo kudala ama-microstructures ahlukene kakhulu. Uma uyawenza, umehluko wokuqina kanye nokuthambekela kokuqina komsebenzi kuzobhubhisa amathuluzi akho uma usebenzisa amapharamitha afanayo. Umsebenzi we-QSY ngalawa ma-alloys akhethekile ugqamisa lokhu—kufanele balungise lonke uchungechunge lwabo lwezinqubo ngokusekelwe ekutheni isitokwe esingenayo sivela ku-investimenti noma ibha eyenziwe. Ukwelashwa kokushisa kwangemva kokukhishwa kokukhululeka kokucindezeleka kubalulekile; yeqe, futhi ingxenye izosonteka ngesikhathi somshini wokugcina, iguqule ingxenye eqondile ibe yizicucu.
Ngikhumbula iphrojekthi yeringi ye-turbine seal. Umdwebo ubufuna ingxubevange esekwe ku-cobalt, i-Stellite 6, ecaciswe ukumelana nokugqoka ngokweqile. Sithole inguqulo yabalingisi. Yayisebenza kahle kakhulu—ikhuluma, ukugqokwa kwamathuluzi kwakuhambisana nezinkanyezi. Inkinga? Inqubo yokuphonsa idale ama-carbide amakhulu, aqinile ku-matrix ephukayo. Isixazululo, esafinyelela kuso ngemva kokuzama nokuzama okuthile okubuhlungu, kwaba ukushintshela enguqulweni eyimpushana ye-metalurgy yengxubevange efanayo, eyanikeza ukusabalalisa kwe-carbide okucolekile, okufanayo. Ihlanzeke ngomshini futhi yenza kangcono. Isifundo: igama lengxubevange liyiresiphi nje; indlela yokukhiqiza iyindlela yokupheka. Ungonakalisa iresiphi enhle ngesu elibi.
Yingakho ukusebenzisana nomphakeli olawula kokubili ukusakaza kanye CNC imishini ngaphansi kophahla olulodwa akukho ukunethezeka; kuyisu lokunciphisa ubungozi. Uma umakhi wemishini engakwazi ukubuyela kumphathi we-Foundry futhi athi, Le nqwaba iyi-gummy, amathuluzi ayalayisha, angakwazi ukuyilandelela emuva ekushiseni okuthululwayo noma izinga lokupholisa. Leyo loop yempendulo ayibonakali enkampanini yokuhweba emsulwa noma esitolo esenza imishini kuphela. Esikhungweni esifana nama-QSY, lokho kuhlanganiswa kuwumkhiqizo.
Ukubekezelelana: Izindleko Zokuphelela
Wonke umuntu ufuna ukubekezelelana okuqinile. Kuzwakala njengekhwalithi. Kodwa ukucacisa ukubekezelela okungu-±0.01mm kuwo wonke umkhakha wokulingisa okuyinkimbinkimbi kuyindlela enhle yokuphinda kathathu izindleko nokubambezela iphrojekthi. Kufanele uqonde ukuthi ukubekezelelana kungokwakho. Ingabe ifanelekile? Ngomsebenzi? Ngebhalansi? Ngokuvamile, i-interface eyodwa kuphela noma ezimbili ezibalulekile ezidinga lokho kunemba. Okunye kungase kukhululeke kakhulu. Ngichithe amahora amaningi nonjiniyela bephikisana ngokubekezelela ezindaweni ezingasebenzi, ngonga amaviki esikhathi sokwenza imishini kanye nezindleko zamathuluzi.
Inselele yangempela ukuphatha izitaki zokubekezelelana kuzo zonke izindlela zokukhiqiza ezihlukene. Ungase ube nendlu okubunjwe kuyo igobolondo lensimbi eyinsimbi I-Qingdao Qiangsenyuan Technology Co., Ltd.(QSY), enomkhono wensimbi engenasici ofakwe kuwo. Ukuncipha kokuphonswa, i-datum yomshini, ama-coefficients okunweba okushisayo—konke kufanele kwenziwe imodeli. Sake saba nenqwaba yemihlangano ebamba ukushisa okusebenzayo. Ngezinga lokushisa legumbi, ukulingana komshini kwakufanelekile. Kodwa sehlulekile ukulandisa ngamazinga ahlukene okukhula okushisayo kwensimbi ekhonjiwe kanye nensimbi engagqwali. Ukulungiswa kwakungewona umshini oqinile; bekuyisibalo sokulingana esihlukile esisuselwe kuzinga lokushisa lesevisi. Imidwebo ibilungile ku-20°C, kodwa umshini awuzange usebenze ku-20°C.
Yilapho isipiliyoni seminyaka engaphezu kwengu-30 singewona umugqa wokumaketha. Iwumtapo walokhu kusebenzisana okushisayo nokokusebenza. Isitolo esisha singase siqinise ukuhlolwa kwezinga lokushisa kwegumbi futhi silethe ingxenye ehlulekayo. Umuntu onokuhlangenwe nakho uzobuza, Kuzosetshenziswa kuphi lokhu? Lithini izinga lokushisa le-ambient? Ingabe ihanjiswa ngamabhayisikili ashisayo? ngaphambi kokuthi bahlele i-CNC.
Ukwehluleka Njengokudilivwa
Ufunda okuningi engxenyeni ephukile kunaleyo esebenzile. Ukuhlola okulimazayo akukhona nje okwe-R&D; kufanele kube yingxenye yenqubo yokufaneleka yezingxenye ezibalulekile. Sasungula inqubomgomo yengcindezi ephezulu izingxenye zomshini: ukuhlolwa kwesihloko sokuqala kuhlanganisa ukusika eyodwa. Hlola ukuzwakala kwangaphakathi kokusakaza, linganisa ukujula kwekesi lokwelashwa kokushisa, bheka i-voids noma okufakiwe. Kuyabiza, kodwa ishibhile kunokukhumbula indawo.
Icala elithile lalihilela amabakaki ensimbi adonsayo okuthutha umsebenzi osindayo. Baphumelele kukho konke ukuhlolwa kwendawo kanye nokuhlolwa komthwalo. Kodwa ngesikhathi sokusika okungahleliwe, sithole i-shrinkage porosity cishe ngo-2mm ngaphansi kobuso endaweni enengcindezi ephezulu. Ngaphansi kokulayisha kwe-cyclic, lokho bekungaba iphuzu lokukhathala kwe-nucleation. I-Foundry, kulokhu, ilungise i-gating yabo kanye nedizayini yesikhuphukeli yaleyo ngxenye yejometri. Ukulungiswa kwakusesikhunjini, hhayi ukukhanda. Uma uhlola kuphela indawo yokugcina eyenziwe ngomshini, uphuthelwa indaba eyenzeka ngaphansi.
Lokhu kushintsha kwemiqondo—kusuka ekuhloleni ukuthobela imithetho kuya ekuhloleni ukuqonda—kubalulekile. Iguqula umnyango wokulawula ikhwalithi kusuka kumgcini wesango ube umthombo wobuhlakani benqubo. Futhi kwakha ubudlelwano obuhlukile nomphakeli. Uma ungaba nengxoxo yobuchwepheshe mayelana nokubala kwe-eutectic cell ku-cast iron noma i-sigma phase embrittlement kuma-welds angagqwali, usuka kumthengi wokuthenga uye kuzakwethu. Abahlinzeki njengalowo ongemuva tsngtaocnc.com bahlanganyele ngendlela ehlukile lapho bebona ukuthi ubheke izinkinga ezifanayo eziyizo.
I-Threshold Enhle Eyanele
Okokugcina, ucezu lokuhlakanipha oluzuzwe kanzima: akuzona zonke izingxenye ezidinga ukuba ubuciko bobuciko. Ukuphishekela ukuphelela kungaba isitha sokusebenza kanye nenzuzo. Kunomkhawulo owanele ochazwe uhlelo lokusebenza. Ubakaki ophethe iphaneli yekhava engabalulekile ayidingi i-aerospace-grade billet aluminium ene-anodizing. I-hot-rolled steel plate, i-laser-cut and deburred, izokwenza umsebenzi ngo-1/10 wezindleko. Ikhono liwukukhomba ngokunembile lowo mkhawulo.
Yilapho isipiliyoni esibanzi kuzo zonke izinto nezinqubo sikhokha khona. Ngokwazi ukuthi endaweni ethile eyonakalisayo, ukubunjwa kwegobolondo okwenziwe kahle ku-CF8M engagqwali kungahle kusebenze kanye nengxubevange ebiza kakhulu eyi-duplex, uma idizayini ilungile. Noma ukuthi endaweni egugileyo, ngezinye izikhathi ukungeza insimbi elula, eshintshwayo eqinile kuhlakaniphile kunokwenza yonke ingxenye ye-monolithic ngengxube ebizayo engagugi. Imayelana nokuklama uhlelo, hhayi ingxenye kuphela.
Ekugcineni, izingxenye zomshini ziwukubonakaliswa ngokomzimba kwezinqumo eziyinkulungwane—izinto ezibonakalayo, inqubo, ukubekezelelana, ukuqeda, ukuhlola. Ipulani liwukuhlebeza kokuqala. Ukubhonga kuvela endaweni eyi-foundry floor kanye nesitolo semishini, lapho ulwazi, ngokuvamile olufundwa ekuhlulekeni kwangaphambilini, luguqule imininingwane ibe yinto esebenza kalula. Kuncane mayelana nedizayini yomuntu ngamunye kanye nokunye mayelana nokusebenza okuqinile, okuphindaphindwayo kulo lonke uchungechunge lwezinqubo ezixhunyiwe. Yilokho okuthengayo ngempela.
