Ubona 'ukusakazwa okuqhubekayo' okujikijelwa kakhulu kulezi zinsuku, kuvame ukushaywa ezintweni zokumaketha ngezinqubo, ngokungagwegwesi, ezingekho luhlaza kakhulu kunalokho ezaziyikho eminyakeni engamashumi amathathu edlule. Uma kuziwa ekubunjweni kwegobolondo lezingxenye zensimbi, impendulo ayiyona yebo noma cha. ‘Kungumthombo, kuya ngokuthi uqhathanisa nani nokuthi usiphatha kanjani isitolo.’ Kusukela lapho ngimi khona, sengichithe iminyaka ngizungeze le migqa, umbuzo wokusimama uncike ocingweni, ukulinganisela okungokoqobo phakathi kokusebenza kahle kwezinto, ukusetshenziswa kwamandla, kanye nokuthi kwenzekani kuso sonke leso sihlabathi ngemva kokunyakazisa ukusakaza.
Inqubo yeShell: Lapho Izinzuzo Zangempela (kanye Nobuhlungu) Zikhona
Umqondo oyinhloko wokubumba amagobolondo muhle: igobolondo elincane, eliqinile lesihlabathi nenhlaka yakha isikhunta esikhundleni setshe elikhulu, elicinene lesihlabathi. Ngokushesha, usebenzisa isihlabathi esincane-kancane kakhulu. Ngomzimba wevalvu yensimbi empunga esiwugijimayo, isikhunta segobolondo singaba nesisindo esingamakhilogremu angu-15, kanti isikhunta sesihlabathi esiluhlaza esingase siphushe amakhilogremu angu-200. Lokho kungukuncishiswa kwempahla okuqondile okuzwakala kukhulu phansi. Awususi ubuningi obungako, awubuyiseli okuningi, futhi ngokomqondo, ulahla imfucuza encane.
Kodwa nansi into yokuqala yokubamba: i-resin. Kuyinto thermoset phenolic. Ukuze ulungise lelo gobolondo, ulibhaka cishe ku-300 ° C. Lokho kusho isihlabathi esiluhlaza okokufaka amandla, njengoba sisetshenziswa 'kubanda'. Ngakho-ke uhwebe ngokubamba kwenqwaba yesihlabathi ukuze uthole amandla okushisa ahlosiwe. Ingabe lokho kuwukuwina okuphelele? Kumamitha ethu wamandla, ngevolumu ephezulu, izingxenye eziphindaphindwayo njengama-manifolds noma izindlu zokumpompa, ukungaguquguquki kanye nesivinini sokubumba igobolondo kuvame ukuholela esikhathini esincane esiphelele sesithando somlilo ngokusakazwa okuhle. Ukwenqaba okumbalwa kusho ukuthi awuncibiliki insimbi enhle, okuwusizinki wamandla omkhulu, ovame ukunganakwa.
Isihlabathi ngokwaso siba yinkinga ingane. Isihlabathi esiluhlaza singagaywa kabusha endlini cishe ngokungapheli ngamanzi ne-bentonite. Isihlabathi segobolondo simbozwa nge-resin esetshenzisiwe, epholile. Awukwazi ukumane ukujikijele emuva ku-mixer. Sizamile ukuyithumela kumaphrosesa ezinkampani zangaphandle ukuze athole kabusha ukushisa, lapho ashisa khona inhlaka. Iyasebenza, kodwa manje usunemali yokuthutha kanye nenye ibhili yamandla. Ezinye izitolo zihlanganisa iphesenti lesihlabathi segobolondo elibuyisiwe libuyiselwe ezinhlanganisweni zesihlabathi ezintsha zama-cores noma isikhunta esingabalulekile, kodwa isenzo sokulinganisa—okuningi kakhulu futhi isiphetho sakho esingaphezulu siyahlupheka, okuholela—ukuqagele—izinsalela eziningi.
I-Cast Iron's Inherent Edge kanye nekesi elisebenzayo
Lokhu akunakwa: ukuqala insimbi njengoba impahla yakho eyisisekelo iyisiqalo sokusimama. Iphuzu layo lokuncibilika liphansi kunelensimbi, ngakho amandla okuqala okuthola uketshezi mancane. Okubaluleke nakakhulu, i-scrap loop yensimbi iqinile. Okwethu okubuyayo—amasango, izikhuphukeli, izikhiqizo ezinqatshiwe—zibuyela emuva ekukhokhisweni, ngokuvamile okwenza u-50-60% wokuncibilika. Kuyiluphu evaliwe ngaphakathi kwezindonga zezitshalo. Ukuphila isikhathi eside kwengxenye yensimbi ebunjwe kahle nakho kuyadlala. Ubakaki bensimbi ababunjwe ngegobolondo bemishini esindayo bangase badlule umshini ngokwawo. Ukuqina kuyimethrikhi yokusimama eyisisekelo engahlali ingene kumaspredishithi okubala kwekhabhoni.
Ngikhumbula iphrojekthi yomhlinzeki wengxenye ye-hydraulic. Babephikisana phakathi kwe-iron ebunjwe ngegobolondo nensimbi eyenziwe ngensimbi. Asisebenzisanga izinombolo kuphela ngezindleko zeyunithi, kodwa ngesilinganiso somjikelezo wokuphila. I-single-piece casting iqede amandla okushisela, izindawo zokuhlola, kanye nemithungo engase yehluleke. Amandla womumo oseduze-netha wenqubo yegobolondo asho isitokwe somshini esincane. Bahamba nabalingisi. Eminyakeni emihlanu kuqhubeke, izinga labo lokungaphumeleli kwenkambu yaleyo ngxenye selisondele ku-zero. Lokho kuyasimama ngomqondo wangempela: ayizange ibuye, ayizange yehluleke, ayidingi ukushintshwa. Leyo yingxabano oyenzayo esitolo, hhayi encwajaneni.
Sisebenza nozakwethu, I-Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), kumaphrojekthi athile engxubevange eyinkimbinkimbi. Sekuyiminyaka engaphezu kwamashumi amathathu ekulingiseni nasekukhiqizeni imishini, futhi ukuthatha kwabo kubonisa lo mbono osebenzayo. Ukuze isikhunta sabo segobolondo sisebenze insimbi kanye nezingxenye zensimbi engagqwali, kugxilwe ekunembeni ukuze kuncishiswe imfucumfucu yomshini wokuwasha. Igobolondo elakhiwe kahle lisho ukuthi awusebenzisi isigayo se-CNC ukuze ususe izinto ezisele ihora, ukuze nje ufinyelele ukubekezelelana. Lokho kongiwa kwamandla angaphansi komfula, ngokombono wesigaba sabo somshini, yingxenye ebalulekile yezindleko eziphelele zezemvelo lapho i-Foundry iyodwa ngokuvamile engayitholi ikhredithi.
I-Gritty Reality kanye Nokuhlolwa Okuhlulekile
Akuzona zonke izinzuzo ezihlanzekile. Iphunga endaweni yokubumba igobolondo lihlukile—lelo phunga le-phenolic resin. Amasistimu okuphefumula komoya kanye nokubamba umoya kufanele abe phezulu, okungenye indlela yokudonsa amandla. Sazama i-bio-based resin binder 'eluhlaza' eminyakeni embalwa edlule. Ukumaketha bekukuhle. Emgqeni, amandla egobolondo ayengahambisani, ikakhulukazi esimweni sezulu esiswakeme. Sithole izinga eliphezulu lokuqhekeka kwesikhunta ngesikhathi sokuphatha, okuholela esikhunjeni esilahliwe ngenxa yokungena kwensimbi. Salihoxisa icala ngemva kwezinyanga ezimbili sadla izindleko. Ukusimama okwehlisa isivuno akusona isiqalisi emakethe yokuncintisana; uyaphuma ebhizinisini. Isifundo sasiwukuthi enye ikhemistri kufanele ihambisane nokusebenza komshini kuqala.
Elinye iqiniso yizindleko zephethini. Ukuze uthole ukubunjwa kwegobolondo, udinga amaphethini ensimbi, ngokuvamile insimbi noma i-aluminium, eyenziwe ngomshini ngezinga eliphezulu. Ziyabiza. Uma wenza umsebenzi wevolumu ephansi, oxubene kakhulu, izindleko zemvelo zokukhiqiza leyo phethini zingahle zingancishiswa ngeqoqo elincane lokulingisa. Inqubo iba kuphela ‘esimeme’ ngempela ekubukeni okuphelele lapho usebenzisa amanani aphezulu noma imijikelezo yokukhiqiza emide kakhulu ukusuka kuleyo phethini efanayo. Uma kungenjalo, ungcono ngenqubo evumelana nezimo, noma ngabe ingasebenzi kahle ucezu ngalunye.
Ngakho-ke, Ingabe Iyasimama? The Shop Floor Verdict
Ngemuva kwakho konke lokhu, ukuthatha kwami yilokhu: ukubumba igobolondo izingxenye zensimbi kungaba umzila ozinzile uma kuqhathaniswa nezinye izindlela eziningi zokusakaza, uma—futhi kukhulu uma—ukusebenza kwakho kulungiselelwe kona. Uma uthela amavolumu aphezulu ezingxenye ezifanayo, ulawula ukubuyiselwa kwesihlabathi sakho ngempumelelo (ngisho noma singekho endaweni), futhi usebenzisa ukunemba kobukhulu ukuze unqamule imfucumfucu yemishini, yebo, usendleleni enhle. Ukusebenza kahle kwezinto ezibonakalayo esiteji sokubumba kungokoqobo futhi kuphawulekayo.
Kodwa uma uyisitolo esincane semisebenzi edubula ulayini wamagobolondo ama-run amafushane, obhekene nokuphathwa kabi kwesihlabathi, kanye namazinga okulwa nezilahliwe, noma iyiphi inzuzo yendawo ezungezile ihwamuka ngokushesha. Ukusimama akukho egameni lenqubo; kuyindlela oyisebenzisa ngayo. Isesigabeni sokuncibilika esigcwele ukubuyisela kwangaphakathi, kumaphethini anakekelwe kahle ahlala amashumi eminyaka, kanye nakunjiniyela wokuklama osebenza nawe ukuze enze ingxenye yakheke, hhayi nje ukuthi isebenziseke.
Ekugcineni, kithi, iyithuluzi. Isikhunta segobolondo siyithuluzi elimangalisayo lemisebenzi ethile, futhi uma sisetshenziswa kahle, alilimazi kangako okukhiphayo okufanayo. Lokho kumayelana nencazelo ethembeke kakhulu yokusimama kwezimboni ozoyithola kumuntu onothuli lwe-resin emabhuthini akhe. Akuyona inguquko; kuwukucophelela, ngezinye izikhathi okungcolile, ukuziphendukela kwemvelo. Futhi lowo ngumsebenzi wangempela.
