Iyini I-Roll Yakhayo?
Ukwakhiwa kwamarola kuyinqubo esebenzisa isethi yamarola abekwe ngokunembile ukuze enze ukugoba okukhuphukayo emgqeni wensimbi ophakelwa ngokuqhubekayo.Ama-roller afakwe ngamasethi endaweni elandelanayo ne-roller ngayinye egcwalisa isinyathelo esisodwa esincane senqubo.Ama-Roller aklanywe ngokucophelela kusetshenziswa iphethini yembali, ekhomba izinguquko ezilandelanayo emgqeni wensimbi.Ukuma kwe-roller ngayinye kudalwe kusukela ezingxenyeni zomuntu ngamunye zephethini lembali.
Umbala ngamunye kuphethini yembali engenhla ubonisa okukodwa kokugoba okusetshenziselwa ukuqedela ingxenye.Imibala ngayinye iwumsebenzi wokugoba owodwa.Ukunikezwa kwe-CAD noma kwe-CAM kusetshenziselwa ukulingisa inqubo yokwenza umqulu ukuze amaphutha noma amaphutha angavinjelwa ngaphambi kokukhiqiza.Besebenzisa izinhlelo zokusebenza zesofthiwe, onjiniyela bangakhetha ukulinganisa namaphrofayela okugoqa noma ukugoba ama-engeli ukuze bakhe amajiyometri amasha ngokuchofoza igundane labo.
Roll Forming Process
Umkhiqizi ngamunye owenza ama-roll unesethi ehlukile yezinyathelo zenqubo yabo yokwenza ama-roll.Ngaphandle kokuhlukahluka, kunesethi yezinyathelo eziyisisekelo bonke abakhiqizi abazisebenzisayo.
Inqubo iqala ngekhoyili enkulu yeshidi lensimbi engaba amayintshi angu-1 ukuya kwangu-30 ububanzi nogqinsi luka-0.012 intshi kuya ku-0.2 intshi.Ngaphambi kokuthi ikhoyili ilayishwe, kufanele ilungiselelwe inqubo.
Izindlela Zokwakha Roll
A) Ukugoqa kweRoll
Ukugoba ama-roll kungasetshenziselwa amapuleti amakhulu ensimbi.Amarola amathathu agoba ipuleti ukuze akhiqize ijika elifunekayo.Ukubekwa kwama-roller kunquma ukugoba okuqondile kanye ne-angle, elawulwa ibanga phakathi kwama-roller.
Ukugoqa Ukwakha Roll
B) I-Flat Rolling
Indlela eyisisekelo yokwenza umqulu yilapho impahla yokugcina inesiphambano esingunxande.Ekugoqekeni okuyisicaba, amarola amabili asebenzayo azungeza ezinhlangothini eziphambene.Igebe phakathi kwamarola amabili lingaphansi kancane kunogqinsi lwempahla, ephushwa ukungqubuzana phakathi kwempahla namarola, okwenza into ibe yinde ngenxa yokuncipha kogqinsi lwempahla.Ukungqubuzana kunciphisa inani lokuguquguquka endaweni eyodwa okwenza amaphasi amaningana adingekile.
C) Ukuginqika komumo/Ukugingqa komumo/Ukugingqika kwephrofayela
Ukugingqa komumo kusikeka izimo ezihlukene kucezu lokusebenza futhi akubandakanyi noma yiluphi ushintsho ebugqileni bensimbi.Ikhiqiza izingxenye ezibunjiwe njengamashaneli amise okwengajwayelekile kanye nokunquma.Izimo ezakhiwe zihlanganisa i-I-beams, i-L-beams, iziteshi ze-U, kanye nomzila wesitimela wamathrekhi wesitimela.
D) Iringithoni
Ekugoqeni kwendandatho, indandatho enobubanzi obuncane bokusebenza igoqwa phakathi kwamarola amabili ukuze yakhe indandatho yobubanzi obukhulu.I-roller eyodwa iyi-drive roller, kanti enye i-roller ayisebenzi.I-roller eguquguqukayo iqinisekisa ukuthi insimbi izoba nobubanzi obungaguquki.Ukuncishiswa kobubanzi bendandatho kunxeshezelwa ngobubanzi bendandatho.Inqubo isetshenziselwa ukwakha izindandatho ezinkulu ezingenamthungo.

E) Ukugingqika kwepuleti
Imishini yokugingqa amapuleti igingqa amashidi ensimbi abe amasilinda amise okuqinile.Izinhlobo ezimbili ezihlukene zalolu hlobo lwemishini kukhona ama-roller amane nama-roller amathathu.Ngenguqulo ye-roller emine, kukhona i-roller ephezulu, i-pinch roller, nama-side roller.Inguqulo ye-roller emithathu inawo wonke ama-roller amathathu akhiqiza ingcindezi enamabili phezulu neyodwa phansi.Umdwebo ongezansi yizinhlelo ezine zamarola ezakha isilinda.
