Aumshini wokwenza roll(noma umshini wokwenza insimbi) wenza ukucushwa okuthile ngemicu emide yensimbi, ngokuvamile egoqekile yensimbi. Ezinhlelweni eziningi, iphrofayili edingekayo ye-cross-section yesiqephu iklanyelwe ngokukhethekile umshini ukugoba insimbi njengoba kudingeka. Ngaphandle kokwenza ama-roll, le mishini yenza imisebenzi eminingana yokwenza insimbi, okuhlanganisa ukusika izinto ezibonakalayo kanye nokushaya ngamasondo.
Imishini yokwenza ama-roll, ingxenye enkulu, isebenza ngomjikelezo oqhubekayo. Impahla ifakwa emshinini lapho uqhubeka khona udlula ezigabeni zokusebenza ngakunye, uphele ngokuphothulwa komkhiqizo wokugcina.
Isebenza Kanjani Imishini Yokwenza Ama-Roll

Umshini wokwenza ama-roll ugoba insimbi ekamelweni lokushisa usebenzisa iziteshi eziningana lapho amarola angashintshi womabili eqondisa insimbi futhi enze ukugoba okudingekayo. Njengoba umugqa wensimbi uhamba emshinini wokwenza ama-roll, isethi ngayinye yamarola igoba insimbi kancane kunesiteshi sangaphambilini samarola.
Le ndlela eqhubekayo yokugoba insimbi iqinisekisa ukuthi ukucushwa kwe-cross-sectional okulungile kufinyelelwa, kuyilapho kugcinwa indawo yesiphambano somsebenzi. Ivamise ukusebenza ngesivinini esiphakathi kwamafithi angu-30 kuya kwangu-600 ngomzuzu, imishini yokwenza ama-roll iyisinqumo esihle sokukhiqiza izingxenye eziningi noma izingcezu ezinde kakhulu.
Ukwakhiwa kweroliimishini futhi ilungele ukudala izingxenye eziqondile ezidinga umsebenzi wokuqeda omncane kakhulu, uma ukhona. Ezimweni eziningi, kuye ngokuthi i-material ibunjwa, umkhiqizo wokugcina ufaka isiphetho esihle kakhulu nemininingwane emihle kakhulu.
I-Roll Forming Basics kanye Nenqubo Yokwakhiwa KwamaRoll
Umshini wokwenza umqulu oyisisekelo unomugqa ongahlukaniswa ube izingxenye ezine ezinkulu. Ingxenye yokuqala yisigaba sokungena, lapho impahla ilayishwa khona. Okubalulekile kuvame ukufakwa kwifomu leshidi noma kuphakelwe kukhoyili eqhubekayo. Isigaba esilandelayo, amarola esiteshi, yilapho ukwakhiwa kwamaroli kwenzeka khona, lapho iziteshi zitholakala khona, nalapho insimbi ibumbeka khona njengoba yenza indlela yayo phakathi nenqubo. Amarola esiteshini awagcini nje ngokubumba insimbi, kodwa angamandla amakhulu okushayela umshini.
Ingxenye elandelayo yomshini oyisisekelo wokwenza umqulu umshini wokunyathelisa osikiwe, lapho insimbi isikwa ibe ubude obunqunyiwe ngaphambili. Ngenxa yesivinini umshini osebenza ngaso kanye neqiniso lokuthi uwumshini oqhubekayo osebenza, amasu okunqamula ukufa okundizayo awavamile. Ingxenye yokugcina yisiteshi sokuphuma, lapho ingxenye eqediwe iphumela emshinini ingene kusidluliseli noma itafula, bese ihanjiswa mathupha.
Ukuthuthukiswa Komshini Wokwenza Roll
Imishini yanamuhla yokwakha amaroli inemiklamo yamathuluzi esizwa ngekhompiyutha. Ngokuhlanganisa izinhlelo ze-CAD/CAM ku-equation eyenza umqulu, imishini isebenza ngamandla ayo aphezulu. Uhlelo olulawulwa ngekhompuyutha luhlinzeka ngemishini yokwenza ama-roll “nobuchopho” bangaphakathi obubamba ukungapheleli komkhiqizo, bunciphise umonakalo nokumoshakala.
Emishinini eminingi yesimanje yokwenza ama-roll, izilawuli ze-logic ezihlelekayo ziqinisekisa ukunemba. Lokhu kubalulekile uma ingxenye idinga izimbobo eziningi noma idinga ukusikwa ibe ngobude obuthile. Izilawuli ezinengqondo ezihlelekayo ziqinisa amaleveli okubekezelelana futhi zinciphise ukunemba.
Eminye imishini yokwenza ama-roll nayo ifaka amakhono okushisela nge-laser noma e-TIG. Ukufaka le nketho emshinini wangempela kubangela ukulahlekelwa amandla okusebenza kahle, kodwa kususa sonke isinyathelo senqubo yokukhiqiza.
Ukubekezelela Komshini Wokwenza Roll
Ukwehluka kwe-Dimensional kwengxenye edalwe ngokwenza umqulu kusekelwe ohlotsheni lwempahla esetshenzisiwe, okokusebenza kokwenza umqulu, kanye nokusetshenziswa kwangempela. Ukubekezelela kungase kuthonywe ukujiya kwensimbi okuhlukahlukene noma ububanzi, i-springback yezinto ngesikhathi sokukhiqiza, ikhwalithi nokuguga kwamathuluzi, isimo sangempela somshini, kanye nezinga lesipiliyoni somsebenzisi.
Izinzuzo Zemishini Yokwenza Roll
Ngaphandle kwezinzuzo okuxoxwe ngazo esigabeni esandulele,ukwakha umquluimishini inikeza umsebenzisi izinzuzo ezithile. Imishini yokwenza ama-roll iyonga amandla ngoba ayisebenzisi amandla ekushiseni—izimo zensimbi ezingeni lokushisa elilingana negumbi.
Ukwakhiwa kweroll nakho kuyinqubo elungisekayo futhi kusebenza kumaphrojekthi anobude besikhathi obuhlukahlukayo. Ukwengeza, ukwakheka kwe-roll kubangela ingxenye eqondile, efanayo.
