Izindawo Ezisebenzayo Zomgcina Wokuthinta Imithwalo Ngokuthe ngqo: Ukwahlukana Okupheleleyo Kwimithwalo Yemetali Ngokubanzi Kwezimali
U umhlaba wokwakha kanye nomthutho wokwakha izinto zasekhanda yisiseko sekuqashiselwa kwezinhlelo zokuthatha imithambo engcwele, ekulungiseni izidingo ezibalulekile zemithambo yemiphefumulo enezimali eziphathelene nezilinganiso. Kukwakha, lezi zinhlelo zihlengela imithambo yesithalimini esincane ukuba ibe yimithambo yokukhazimula (kubudaka, amakhaya aphezulu, namaholide) nemithambo yemphambu ethunywa ngokugqoka (kuphapha, amaplanga, namacala okugcina)—indlela yabo yokuthatha ngokushesha kuyabekisa ubude obufanayo nobunzima bokuthanda, okubalulekile ukwenza konke okukhokelela kumandla wokukhakha nokufaneleka ngezimali zokwakha. Kusayensi yezixhobo, zihlengela imithambo ye iron, copper noma aluminum ukuba yizinto ezihlukene njengezinkunkuma, i-screws, i-hooks, namacala emithambo: ukulawula kwezinyikima kwemikhumbi kuyasusa ukugayaza okuyinxiba okuyingxenye, ukuqinisekisa ukuthi izinxenye ziyafaka kuzilinganiso zilandelayo futhi ziqagqa ngempumelelo. Ezinye izindawo ezikhulu zokwakha izixhobo nezinye izigaba ezincane zasekhaya zilondoloza lezi zinhlelo—izinhlelo zangaphandle zihlengeza ukusebenzisa okuncane, kodwa izinhlelo ezinezimali eziningi zihlengeza ukukhiqizwa okuphelele okuphezulu, kanti kuzinzuzela kakhulu kulesi sigaba.
U umndini wamandla nezinhlelo zedijithali kuyaphila kakhulu kumashini okugcwalisa imithambo engqondweni yokuphambana ukuze akhiye imithambo enobuthulekile obuphezulu, emikhathazini encane. Le mashini agcwalisa imithambo yekopere esihlangothini noma yialuminum kuze kube yizindlela ezincane kakhulu (ezingancane ngaku-0.01mm) efanele ekugcineni kwamandla (ukudala kwezindlu, izigaba zokusebenza), izindlela zokubaluleka kwezikhwama (izikhamphela, izivivinyo, iziqhamo), namacala ebhomu (izixhobo zezindlu, izinhloso zokusebenza, nezibhomu ze-EV). Isakhiwo sokuphambana singavimba ukutshebha kwemithambo, kuvikelela amafomu ahlanzekileyo nemisebenzi efanayo—lokhu kubaluleke kakhulu ekulungiseni ukungabi nalutho lwamanzi, ukulungiselela ukuthembeka kancane, nokulungisa ubunzima bokusebenza kwesibhomu. Kwi-elektronics ezinezindlela ezide (isb. i-smartphones, i-laptops) nezase-EV, le mashini futhi ihlawula imithambo yekopere egcinekile noma egcinekile ngisiliva (ngokulindela ukuthembeka komoya nokunakekelwa kobuthulekile), ukufaka izimali ezibophaza kwezimali ngokuncane nokulindela. Ngemuva kokuba i-electronics ibe yincane kunesikhathi kanye nokuthuthuka kwe-EV kusondeza, isicelo sezigamekeli ezilungileyo zokugcwalisa imithambo engqondweni yokuphambana kulesi sifundo siyakhula ngokushesha.
Amathuthuka amakhubazekayo emandla ephezulu phakelisa isilinganiso sebukeko lwamashini okuphuma kwezwire engcwele, ukusebenzisa inkinga yabo yokuphatha izimboni ezikhethekile kanye nokuhlanza imithetho emakhulu. Kwi-industri yesimoto, bayakha izwire zamaloyi (isiSteel-isiBrass, isiSteel esingcolile) zezinhlelo zokubandakanya, izwire zokulungisa izihlalo, nezwire zokuxhumeka kwebhatere yesimoto se-EV—lezi zwire zidinga ukulandelana kwezinkinga, ukukhathazeka komthwalo, nokwandisa konke okunempela, okunikezwa ngendlela yokuphuma eyaziwayo kwilishini. I-industri yesifo isebenzisela ukwenza izwire ezingcolile (umaloyi wesiTitanium, iNitinol) zezixhumanisi zesifo (iziphiqo, izivuno), nezinto ezifakelwayo (izihlwebo zomkhuhlane, izihlwebo zezililo): le mishini ihlanza emhlabeni engafuneki kuyo amathambo futhi ibeke ikontrola ephepha kwe-diameter ukulandela imithetho ye-ISO 13485 ne-FDA. Ngaphezu koko, indalali yesigodini isebenzisa ukuphatha izwire ezilula kodwa ezikhulu (isiTitanium, iInconel) zezinhlelo zokubophezela kwezimoto nezinqubo zezinkanyezi, lapho iziphazamo ezincane zezwire zingakhipha ububi. Lezi zindlela ezikhethekile zibonisa indima yesishini ekusindiseni iz industri ebalaseleyo, ezisebenzisa teknoloji.
