Uma amaklayenti ebuza ngezindleko zokuphonswa kwesihlabathi, into yokuqala engiwatshela yona ukuthi akhohlwe intengo yekhilo ngalinye okungenzeka ukuthi ayibonile ku-inthanethi. Lokho ugibe olukhulu kakhulu. Izindleko zangempela akusona nje isisindo sensimbi; kuyizinto zonke ezenzekayo ngaphambi kokuba insimbi encibilikisiwe ithinte ngisho nesihlabathi. Ngichithe iminyaka kuma-Foundries, futhi amashidi wokucaphuna afika edeskini lami avame ukuphuthelwa abashayeli abafihliwe. Akukhona mayelana nokuthola eshibhe kakhulu, kodwa mayelana nokuqonda ukuthi yini oyikhokhelayo. Masiyihlukanise ukusuka ephethini ukuya phezulu.
Lapho Imali Iya Khona Empeleni: Iqala Ngephethini
Wonke umuntu ugxila ezintweni ezibonakalayo-insimbi ekhonjiwe, i-ductile iron, insimbi. Kodwa izindleko zephethini zingumbulali wesabelomali othule, ikakhulukazi ukugijima kwevolumu ephansi. Iphethini yokhuni elula yendlu yegiya elilodwa? Mhlawumbe iyalawuleka. Kodwa uma udinga ukuzinza kwe-dimensional yezingcezu ezingu-500, ubheka iphethini yensimbi eyenziwe ngomshini. Lokho kuwutshalomali lwezibalo ezinhlanu ngaphambi kokuthi wenze ingxenye eyodwa. Inketho lapha isho yonke into: ikhwalithi yesikhunta, ama-engeli okubhala, amandla okunqamula ngaphansi. Yenza iphethini ibe yiphutha, futhi iyunithi ngayinye ibiza kakhulu ngenxa yokulungiswa okudingekile kukho konke ukusakaza. Ngibone amaphrojekthi lapho izindleko zephethini zeqe inani lezindleko zokusakaza zeqoqo lokuqala. Izindleko ezinkulu ezidinga ukuncishiswa, futhi akubona bonke abahlinzeki abakubeka obala ngalokho.
Bese kuba namabhokisi asemqoka. Uma ingxenye yakho inemigodi yangaphakathi, udinga ama-cores. Ingqikithi ngayinye idinga ibhokisi layo ukwenza izimo zesihlabathi. Ubunzima obuningi = amabhokisi amaningi = amathuluzi angaphambili. Lapha kulapho ukusebenza nozakwethu onolwazi like I-Qingdao Qiangsenyuan Technology Co., Ltd. (QSY) kwenza umehluko. Ngeminyaka yabo engu-30 ekulingiseni, bayakwazi ukudizayina amaphethini namabhokisi angumongo wokwenziwa, ngokuvamile baphakamisa izinguquko ezincane ezinciphisa kakhulu inkimbinkimbi yamathuluzi ngaphandle kokuthinta umsebenzi. Yilobunjiniyela bangaphambili obulawula ingemuva izindleko zokuphonsa isihlabathi.
Indaba yephethini nayo ibalulekile. Ngokuhamba isikhathi eside, insimbi iyona ndlela kuphela. Kodwa ngake ngaphusha iphethini ye-epoxy yokusetshenziswa okuphakathi kwamavalvu ensimbi engenasici, ngicabanga ukuthi sizokonga. Umnyakazo omubi. Ukushisa nokuhuzuka okuvela esihlabathini se-silica kwenze iphethini yehle ngomjikelezo we-100, okwethula ukuhlukahluka okuholela ekubunjweni okulahliwe. Ukulondoloza okwakucatshangwa ukuthi kwaqedwa ukwenqatshwa. Siyini isifundo? Ungashibhi ngokusebenza kwamathuluzi. Iphethini iyisisekelo saso sonke isakhiwo sakho sezindleko.
Amacala Afihliwe: Isivuno Nokuqeda
Isivuno imfihlo engcolile ye izindleko zokuphonsa isihlabathi. Uyala i-100 kg ye-castings, kodwa kufanele uthele i-150 kg yensimbi encibilikisiwe. Kungani? Isistimu yokugenca nezikhuphukeli—lezo ziteshi ezifaka insimbi emgodini wokukhunta—ziyingxenye yesisindo esitheliwe kodwa ziyanqunywa futhi zigaywe kabusha. Isivuno siyiphesenti lesisindo esithululiwe esiba ingxenye yokugcina ethunyelwe. Ingxenye eyinkimbinkimbi, enezindonga ezincane ingase ibe nesivuno esingu-50% noma ngaphansi. Ngakho-ke, izindleko zakho zezinto ezibonakalayo ziphindwe kabili. Abahlinzeki abanokulawulwa kwezinqubo okungekuhle banesivuno esincane, futhi ukhokhela lokho kumosha.
Yilapho ubuchwepheshe benqubo buhlukanisa izitolo. I-Foundry ethuthukisa idizayini yokugenca futhi isebenzisa isofthiwe yokulingisa ingaphusha isivuno sibe phezulu. Ngikhumbula iphrojekthi yobakaki omkhulu wokukhweza i-iron ductile kwa-QSY. Onjiniyela babo baklame kabusha isango, besuka esangweni elingokwesiko eliphezulu baya ohlelweni olulawulwayo lokugcwalisa ngezansi. Inyuse isivuno sisuka ku-58% saya ku-72%. Lolo shintsho olulodwa lwehla izindleko zokuphonsa isihlabathi cishe ngo-8% ohlangothini lwempahla kuphela. Akuwona umlingo; kusetshenziswa i-metallurgy kanye ne-fluid dynamics.
Bese kufika ukuqeda. Malini CNC imishini iyadingeka? Ukwenziwa kwesihlabathi kukunikeza ukuma okuseduze, kodwa izindawo ezibucayi zihlala zidinga ukwenziwa ngomshini. Imilimitha ngayinye yesitoko osishiya sisebenza ngomshini siyinsimbi eyengeziwe oyikhokhe ukuze usakaze, bese ukhokha isikhathi esengeziwe ukuze unqamule. Ngiphikisane nabaklami amahora amaningi ngokwengeza isibonelelo sikamshini esingu-1mm ebusweni obungabalulekile uma kuqhathaniswa nokucacisa ukuphela kokusakazwa. Ukuthi 1mm endaweni enkulu yengeza isisindo, kunciphisa isivuno, futhi kwandisa isikhathi somshini. Ukwehla kwezindleko. Umkhuba ongcono kakhulu uwukuqoka izixhumanisi ezisebenzayo kuphela njengezindawo ezinomshini. Ukulingisa makube ukulingisa yonke indawo.
Ivolumu kanye neJiyomethri: Ubudlelwano Obungeyona Umugqa
Izindleko azilingani ngokuhambisana nevolumu. Izingcezu zokuqala eziyi-100 zibiza kakhulu ngoba zithwala umthwalo ogcwele wephethini nokusetha. Ijika lezindleko liphansi kakhulu ngemva kwezingcezu ezingamakhulu ambalwa, njengoba uhlanganisa izindleko eziguquguqukayo njengensimbi, amandla, nomsebenzi wokubumba. Kodwa kukhona elinye iwa: i-geometry. Umumo olula, ovimbekile ushibhile ukubumba kanye nengqikithi. Engeza inqwaba yezimbambo zangaphakathi, izindonga ezizacile ezincikene nezingxenye eziwugqinsi, noma ukubekezelela okuqinile kubukhulu be-cast-cast, futhi ucela inkinga.
Izingxenye eziwugqinsi zipholile kancane, okuholela ekushwabaneni kwe-porosity. Izingxenye ezizacile zipholile ngokushesha. Zihlanganise, futhi udala amaphuzu okucindezeleka nezinyembezi ezingaba ezishisayo. I-Foundry kufanele yengeze ukugodola (ukufakwa kwensimbi esihlabathini) noma izikhuphukeli ezikhethekile zokulawula ukuqiniswa, okwengeza ukusebenza nokuba yinkimbinkimbi. Lokhu ngikufunde kanzima ngomklamo wezindlu wephampu. Sibe ne-flange engu-3mm eduze kwe-boss ekhwezayo engu-25mm. Ukulingisa kwakulokhu kuqhekeka. Isixazululo kwakuwukwengeza i-fillet kanye noshintsho oluhamba kancane kancane, ithimba labaklami eliqale ukumelana nalo ngenxa yezizathu zobuhle. Senze noma kunjalo, kwanqamuka imifantu, nezindleko zehla ngoba izinga lokwenqaba lehla. Kwesinye isikhathi, ukudizayinela inqubo kukonga kakhulu izindleko.
Leli inani lezitolo ezihlanganisiwe eziphatha kokubili ukusakaza kanye CNC imishini. Inkampani efana QSY, enikeza kokubili, ingaluleka kusukela ekuqaleni. Bangase bathi, Shiya lolo donga njengoba lusakazwa, kodwa yenza lolu donga lube ngu-2mm lube ngaphansi ukuze silumshini lube sekupheleni futhi lubekezeleleke. Babona lonke uhambo ukusuka esihlabathini kuya engxenyeni eqediwe, ngakho iseluleko sabo sezindleko siphelele, asihlukanisiwe.
Inganekwane Ebalulekile: Akuyona Yonke Insimbi Elinganayo
Insimbi nje iwumusho ongenza ngiqhanyelwe. Insimbi empunga, i-ductile iron, i-austempered ductile iron (ADI)—ngayinye inezindleko zempahla eluhlaza ehluke kakhulu kanye nemfuneko yokucubungula. I-Ductile iron idinga ukwelashwa kwe-magnesium, okungeza izinyathelo nezindleko. Ama-alloys akhethekile? Omunye umhlaba lowo. QSY ibala izinto ezifana nama-alloys asekelwe ku-nickel, angabiza izikhathi ezingu-10-20 ngaphezulu ngekhilogremu kune-iron evamile empunga. Kodwa izindleko ezinkulu akuzona nje intengo ye-ingot; wukuphatha. Lawa ma-alloys avame ukudinga ukulawulwa okuqinile kokuncibilika, izihlabathi ezibumbayo ezihlukene ukuvimbela ukungcola, nokwelashwa okukhethekile kokushisa.
Ukukhetha impahla efanele kuwukuhwebelana kwezindleko zokusebenza. Ngasebenza ngepuleti lempahla yokumba. I-spec yokuqala bekungeyensimbi emhlophe ye-chromium ephezulu yokumelana nokuhuzuka okwedlulele. I izindleko zokuphonsa isihlabathi yayiphezulu, futhi ukuyilungisa kamuva kwaba yiphupho elibi. Siyifanise ngensimbi ene-alloy ephansi enembondela engaphezulu eqinile. Yenze ama-80% kanye nama-50% wezindleko eziphelele. Iklayenti lalijabule. Indima ye-Foundry ukwethula lezi zinketho, hhayi nje ukwenza ukuphrinta ngokungaboni.
Izinga le-Scrap nalo lincike ezintweni ezibonakalayo. Izimpahla eziqinile zijwayele ukuphuka ngesikhathi sokunyakaziswa (ukukhipha isihlabathi) noma ukusika amasango. Izinga eliphezulu le-scrap linyusa buthule izindleko zakho ezisebenzayo engxenyeni ngayinye enhle. Umsunguli othembekile uzoba nezinqubo ezizinzile zokugcina leli zinga liphansi, yingakho ukuphila isikhathi eside ebhizinisini, njengeminyaka engamashumi amathathu ye-QSY, kuvame ukuhlobana nezindleko ezifihliwe eziphansi. Bakubonile ukwehluleka futhi bakhe amasistimu ukuze bakugweme.
Ngale Kwengcaphuno: Isamba Sezindleko Zobunikazi
Ekugcineni, okwangempela izindleko zokuphonsa isihlabathi yisamba sezindleko zobunikazi. Ukulingisa okushibhile okuhlulekayo emsebenzini noma okubangela amaviki okusebenza kabusha esitolo sakho semishini ingxenye ebiza kakhulu oyoke uyithenge. Ukuvumelana kuyisihluthulelo. Ingabe ukulingisa kuka-500 kuzofana nokokuqala? Ukuhluka kobukhulu kuthinta umugqa wakho wokuhlanganisa. Ukufakwa noma i-porosity kungabangela ukuvuza noma ukwehluleka kwesakhiwo.
Yilapho ukugunyazwa nokucubungula imibhalo kubalulekile. Isitifiketi esifanelekile sezinto ezibonakalayo, umbiko wokuhlolwa kwesihloko sokuqala, amashadi okulawula inqubo—lokhu kwengeza ishelu ezindlekweni kodwa konga intuba enkulu engozini. Ezingxenyeni ezibalulekile, ngihlala ngibhajethela lokhu. Kungumshwalense.
Ngakho, uma uhlola izindleko zokuphonsa isihlabathi, bheka udlule ekugcineni kwesisho. Buza isu lephethini, buza ngesivuno esilindelekile, qonda umgwaqo oqedwayo, bese ukhetha uzakwethu obona isithombe sonke. Umgomo awulona inani eliphansi kakhulu ngesiqephu ngasinye; yizindleko eziphansi kakhulu zengxenye ethembekile, esebenzayo ekhipha umkhiqizo wakho emnyango. Leso yisibalo esibalulekile esitezi sefekthri.
