Lapho onjiniyela besithumela isicelo sokucaphuna, umbuzo owodwa uvela cishe kuzo zonke izingxoxo: "Yikuphi ukubekezelelana ongakubamba?" Umbuzo onengqondo - kodwa futhi ungomunye lapho ulwazi oluncane longa khona imali eningi. Ukubekezelela okucaciswe ngokweqile engxenyeni yabalingisi kukhuphula ngokuthula izindleko ngomshini ongadingekile, ukuhlola okungeziwe, kanye nezilahlwa. Ukuzicacisa kancane kudala izinkinga zokuhlanganisa ezansi nomfula. Lo mhlahlandlela uchaza ukuthi kusho ukuthini ukubekezelela ukukhishwa kwe-investimenti, ukuthi uhlelo lwebanga le-CT lusebenza kanjani, nokuthi abathengi abanolwazi balusebenzisa kanjani ukuze bathole ukunemba abakudingayo ngentengo ephansi kakhulu.
Kungani Ulimi Lokubekezelelana Lubalulekile Ekusakazeni
Izitolo zomshini zikhuluma ngokwamabanga e-IT (ISO 286) - ukubekezelela kukalwa ngekhulu lemilimitha, okufinyelelwa ngokukhipha izinto ezisetshenziswayo ngamathuluzi aqinile, ahlelekayo. Ama-Foundries akhuluma ulimi oluhlukile. Izingxenye zolingisi zakhiwe ngokuqiniswa kwensimbi ewuketshezi ngaphakathi kwesikhunta, futhi ukuhluka kwazo kobukhulu kubuswa ukunemba kwephethini ye-wax, ukunwetshwa kwegobolondo, ukuncipha kwe-alloy, kanye nengxenye yejometri.
Izinga lamazwe ngamazwe lokubekezelelana kokusakaza yi -ISO 8062 , echaza uchungechunge lwamabanga "Okubekezelela Ukusakaza" — amabanga e-CT . Lapho inombolo ye-CT iphansi, kuqina ukubekezelelana. Ukuqonda ukuthi ingxenye yakho iwela kuphi kulesi sikali kuyisisekelo sazo zonke izinqumo zokuthengwa kwempahla.
I-CT Grade System ngokubuka nje
Amabanga e-CT anikeza ibhendi yokubekezelela ngokusekelwe kubukhulu besici besici. Ibanga elifanayo le-CT livumela ibhande eliphelele elibanzi endaweni enkulu kunelincane. Njengereferensi esebenzayo yokusakazwa kokutshalwa kwezimali kwensimbi nensimbi:
- I-CT4–CT5 - isimo esingcono kakhulu sokutshala izimali ezincane (imvamisa engaphansi kuka-~50 mm) kunqubo ye-silica sol
- I-CT5–CT6 — uhla lwezentengiselwano olujwayelekile lokusakazwa okuningi kwe-silica sol kufika ku-~200 mm
- I-CT6–CT8 — ejwayelekile ekubunjweni kwenqubo yengilazi yamanzi kanye namajiyometri amakhulu, ayinkimbinkimbi
- I-CT8–CT12 - indawo yokusakazwa kwesihlabathi nokuphonsa okufayo ngokusalungiswa okuphezulu kanye nokuhluka komugqa wokuhlukanisa
Uma kuqhathaniswa, ubukhulu obungu-100 mm ngaphansi kwamabanga ahlukene bunikeza isithombe esinzima: I-CT4 ivumela cishe ±0.26 mm, CT5 cishe ±0.36 mm, CT6 mayelana ±0.5 mm, kanye ne-CT9 - isibalo esinengqondo sokuphonsa isihlabathi - cishe ±1.5 mm. Kungakho ukukhetha kwenqubo kukodwa, ngaphambi kwanoma yimuphi umshini, kukuthengela ukuthuthukiswa okuphindwe kabili kuya kane ekunembeni njengokunemba.
Yini Empeleni Eqhuba Ukubekezelelana Ekusetshenzisweni Kwezimali
Izinto ezine ezilawula ukuthi ingxenye yakho ihlala kuphi esikalini se-CT:
1. Ukunemba kwephethini ye-wax. Bonke ubukhulu bokubunjwa buzuza njengefa ukunemba kwephethini ye-wax eyakhile. Umjovo we-wax wesimanje one-aluminium efayo ubamba amaphethini kumakhulu ambalwa wemilimitha, kodwa ukuncipha kwe-wax, izinga lokushisa lokufa, nokucindezela komjovo konke kuyahluka kancane phakathi kwamashothi. Lona owokuqala - futhi omkhulu kunawo wonke - onikelayo ekushintshanisweni kokusakaza, futhi yingakho ikhono lobukhulu lingenakuhlukaniswa kusukela kukhwalithi yamathuluzi ephetheni.
2. Ukuziphatha kwegobolondo nensimbi. Igobolondo le-ceramic liyakhula kancane ngesikhathi sokudubula, futhi yonke ingxubevange iyancipha ekuqinisweni - i-carbon steel cishe u-2%, insimbi engagqwali 2.5-3%. I-shrinkage ayifani ngokuphelele: ithonywa ukushintsha kwesigaba, indawo yokulingisa, nendlela onjiniyela be-Foundry abaphakela ngayo. Izingxenye eziyinkimbinkimbi ezinoshintsho olusheshayo lwesigaba ngeke zinciphe ngokufanayo kuzo zonke izindawo, futhi abasunguli abanekhono banxephezela lokhu ngephethini yokufa.
3. Ingxenye yejometri. Izingxenye ezinde ezincanyana zingahlanekezela ngesikhathi sokususwa kwegobolondo noma ukwelashwa kokushisa; izingxenye ezinezici ezihlukaniswe kabanzi ziqongelela iphethini nokuhlukahluka kwamagobolondo kuso sonke isikhathi. Isici esingu-400 mm kude nedatha ngeke sibambe ibhande elifanayo njengendawo engu-40 mm kude - hhayi ngenxa yokuthi i-foundry ayinaki, kodwa ngenxa yokuthi iphutha linqwabelana ngebanga.
4. Umzila wokucubungula. Amagobolondo engilazi yamanzi ashibhile kodwa azinzile ngokwesilinganiso kunamagobolondo e-silica sol. Uma umdwebo wakho ubiza i-CT5 kuwo wonke amabhodi, ucacisa i-silica sol — futhi intengo iyayibonisa. Uma i-CT7 yanele ngokweqiniso ezicini ezingabalulekile, ingilazi yamanzi ingase iwine isilinganiso.
I-As-Cast vs Machined: Isinqumo Esonga Imali Eningi
Umsebenzi owodwa obaluleke kakhulu ekuthengeni izimpahla ukuhlela zonke izici emdwebeni zibe amabhakede amathathu:
Ibhakede 1 - I-As-cast ilungile. Izindawo ezingasebenzi, izici zokusula, amaphrofayili wezimonyo. Ukucacisa i-CT6 njengoba-cast lapha kwanele ngokuphelele. Ukulungisa lezi zici kuwudoti omsulwa.
Ibhakede 2 - As-cast ngebhendi elawulwayo. Izici ezihambisana nezingxenye ezithambile, ezitholakala ngokukhululekile, noma ezithwala ama-seal zingase zidinge kangcono kunekhono elijwayelekile lokusakaza. Abasunguli bangakwazi ukuqinisa lawa mabhendi ngokulawulwa kwephethini okuzinikele, amasampula asuselwa kugeji, kanye nokwenziwa kwemishini ekhethiwe kwama-datum preps - ngaphandle komshini ogcwele.
Ibhakede 3 - Kumele wenziwe ngomshini. Iphethe izibhobo, i-H8/H7 iyalingana, izimbobo ezinentambo, ubuso be-gasket, izindawo ezifaka amagiya. Ayikho inqubo yokulingisa eletha i-IT7 ngokuqondile; lezi zici zithola imvume yomshini engu-1.5-3 mm futhi ziqedwa ku-CNC.
Imidwebo ecacisa ngengubo engu-±0.05 mm yonke indawo iphoqa abasunguli ukuthi bacaphune umshini ogcwele wayo yonke indawo. Imidwebo efakwe ebhakedeni ngobuhlakani njalo yonga u-20–40% wokuqukethwe kwemishini. Uma sibuyekeza imidwebo e-Ningbo Ruican, lokhu kuvivinya kwamabhakede kuyinani lokuqala esiyengezayo - ngaphambi kokuthi kuthelwe noma iyiphi insimbi.
Ukucaba, Ukuqondile, nezinye Izingcingo Zejiyomethri
Amamaki e-CT amboza ukubekezelelwa kosayizi, kodwa ukubekezelelwa kwejiyomethri - ukucaba, ukuqondile, ukuma - kulandela ukucabanga kwabo siqu. Amandla ajwayelekile okulingisa wensimbi engu-150 mm yokutshala imali acishe abe isicaba esingu-0.5–1.0 mm. Uma ubuso obuvaliwe budinga ukucaba okungu-0.05 mm, lokho kuwumsebenzi womshini, isitobhi esigcwele. Ukubekezelela indawo kumaphethini embobo ecijile kuncike ekutheni izimbobo ziyajikijelwa noma ziyabholwa: izimbobo zabalingisi zilandela ukunemba kwamathuluzi (cishe ±0.3–0.8 mm ukuma kosayizi abamaphakathi), kuyilapho amaphethini abhoboziwe azuza ukunemba kwe-CNC (±0.05 mm noma okungcono). Ukucacisa ama-callouts aqinile emigodini yokuphonswa kungenye yezinto ezivame kakhulu - futhi okugwemeka kakhulu - ukubekezelela ukucaciswa okuningi esikubonayo.
Ungasifunda Kanjani Isimangalo Sokubekezelela I-Foundry
Uma umphakeli ethi "siphethe i-CT5," buza imibuzo emithathu:
- Ngamuphi usayizi? I-CT5 ku-25 mm ihluke kakhulu ku-CT5 ku-300 mm. Cela ibhande lokubekezelela ngobukhulu bakho bangempela obubucayi.
- Kuyiphi inqubo? I-silica sol noma ingilazi yamanzi? Intengo yokucaphuna iyakutshela, kodwa umdwebo akufanele uqagele.
- Ngaliphi ikhono ledatha? I-Foundry elandelela imiphumela enobukhulu ku-CMM futhi ingacaphuna amanani e-Cpk ezicini ezibucayi ingumnikezeli ohlukile kwelinye elicaphuna amathebula amandla okuzisholo. Ngezingxenye ezibalulekile zokuphepha noma zomkhiqizo we-serial, cela ucwaningo lwamakhono kuma-athikili okuqala.
Uhlu Lokuhlola Ukubekezelela Okusebenzayo Kwe-RFQ Yakho Elandelayo
- Yisho ibanga le-CT elimisiwe njenge-cast lengxenye (i-CT5 noma i-CT6 ye-silica sol ijwayelekile), bese ubhala ngaphezulu lapho kudingeka khona.
- Maka izindawo ezifakwe ngomshini ngokucacile futhi uchaze uhlelo lwe-datum - ochwepheshe bemishini badinga ama-datum aphindaphindekayo azosebenza kuwo.
- Gcina inani lezilinganiso ezibucayi lincane. Izici eziyishumi ezibaluleke ngempela ezinokulandelela kwe-Cpk kwehlula ezingamashumi amane "ezibalulekile" ngokukhululeka.
- Nikeza umsunguli umsebenzi wengxenye. Ukwazi ukuthi i-bore ithwala i-bushing kusivumela ukuthi siphakamise inhlanganisela efanele yokulawula ukusakaza kanye nephasi yomshini wokukhanya.
- Cela imibiko yobukhulu be-athikili yokuqala enamanani alinganisiwe wangempela, hhayi nje ukudlula/ukwehluleka.
Umugqa Ophansi
Ukutshala imali kuletha ukunemba okuqeda umshini omningi - kodwa kuphela uma umdwebo uvumela lokho. Abathengi abaqondayo amamaki e-CT, bafaka amabhakede izici zabo phakathi kwe-cast kanye nomshini, futhi baxoxe ngezimfuneko zokusebenza ngokukhululekile ne-Foundry njalo bathola izingxenye ezifanele, ngamanani adlula kokubili izingxenye ezifakwe ngomshini ngokugcwele kanye nezinqubo zokulingisa ezinganembe kangako.
E-Ningbo Ruican, sakha i-silica sol nengilazi yokutshala imali yengilazi yamanzi ngokuqedwa kwe-CNC yangaphakathi, futhi sibuyekeza yonke imidwebo ukuze sibekezelelane kangcono ngaphambi kokucaphuna - isevisi efakwe ne-RFQ yakho. Sithumelele ingxenye yakho yomdwebo futhi sikubonise ukuthi iziphi izici esingaziletha njenge-cast, nokuthi yini lokho okusindisayo.
