Yintoni umqulu oyilwayo?
Ukwenziwa komqulu yinkqubo esebenzisa iseti yeerola ezibekwe ngokuchanekileyo ukwenza ukugoba ngokuqhubekayo kumcu wesinyithi owondliwe ngokuqhubekayo.Ii-roller zifakwe kwiisethi kwisigxina esilandelelanayo kunye ne-roller nganye egqiba inyathelo elincinci lenkqubo.Ubume be-roller nganye yenziwe kumacandelo ngamanye eentyatyambo zeentyatyambo.
Umbala ngamnye kule pateni yeentyatyambo ungentla ubonisa enye yeegophe ezisetyenzisiweyo ukugqibezela inxalenye.Imibala yomntu ngamnye ngumsebenzi wokugoba omnye.Ukunikezelwa kwe-CAD okanye i-CAM kusetyenziselwa ukulinganisa inkqubo yokwenza umqulu ukuze iimpazamo okanye iimpazamo zinokuthintelwa ngaphambi kokuveliswa.Ukusebenzisa usetyenziso lwesoftware, iinjineli zinokukhetha ulungelelwaniso kunye neeprofayile zokugoba okanye ukugoba ii-engile ukwenza iijiyometri ezintsha ngokucofa imouse yazo.
Inkqubo yokwenziwa komqulu
Umenzi ngamnye wokwenza umqulu uneseti eyahlukileyo yamanyathelo enkqubo yawo yokwenza umqulu.Nokuba zeziphi na iinguqu, kukho isethi yamanyathelo asisiseko asetyenziswa ngabavelisi.
Inkqubo iqala ngekhoyili enkulu yentsimbi enokuthi isuse kwi-intshi eyi-1 ukuya kwi-intshi engama-30 ububanzi kunye nobukhulu be-0.012 intshi ukuya kwi-intshi ye-0.2.Ngaphambi kokuba ikhoyili ilayishwe, kufuneka ilungiselelwe inkqubo.
Iindlela zokwenziwa komqulu
A) Ukugoba umqulu
Ukugoba ukugoba kungasetyenziselwa iipleyiti ezinkulu zentsimbi.Iirola ezintathu zigoba ipleyiti ukuvelisa igophe elifunekayo.Ukubekwa kwee-roller kunquma ukugoba okuchanekileyo kunye ne-angle, elawulwa ngumgama phakathi kwee-roller.
Ukugoba uKubumba umqulu
B) Ukuqengqeleka okuMcaba
Ifom esisiseko yokuqulunqa i-roll kuxa izinto zokuphela zine-rectangular cross-section.Kwi-flat rolling, iirola ezimbini ezisebenzayo zijikeleza kwicala elichaseneyo.Umsantsa phakathi kwee-roller ezimbini ungaphantsi kancinci kunobunzima bezinto eziphathekayo, ezityhalwa ngokungqubuzana phakathi kwezinto kunye ne-roller, eyandisa izinto eziphathekayo ngenxa yokuncipha kwezinto eziphathekayo.I-friction inciphisa inani le-deformation kwi-pass eyodwa eyenza iipasi ezininzi eziyimfuneko.
C) Ukuqengqeleka kweMilo/Ukuqengqeleka kweMilo yeZakhiwo/Ukuqengqeleka kweProfayili
Ukuqengqeleka kobume kusika iimilo ezahlukeneyo kwindawo yokusebenza kwaye akubandakanyi naluphi na utshintsho kubunzima besinyithi.Ivelisa amacandelo abunjiweyo anjengemijelo emise ngendlela engaqhelekanga kunye ne-trim.Iimilo ezenziweyo ziquka ii-I-beams, ii-L-beams, iitshaneli ze-U, kunye neereyili zeendlela zikaloliwe.
D) Ukuqengqeleka kweRingi
Kwi-ring rolling, i-ring ye-workpiece encinci ye-diameter ihlanganiswe phakathi kwee-roller ezimbini ukwenza i-ring ye-diameter enkulu.I-roller enye yi-drive roller, ngelixa enye i-roller ingenzi lutho.I-roller ye-edging iqinisekisa ukuba isinyithi siya kuba nobubanzi obuqhubekayo.Ukunciphisa ububanzi bendandatho bubuyekezwe ngobubanzi bendandatho.Inkqubo isetyenziselwa ukudala amakhonkco amakhulu angenamthungo.

E) Ukuqengqeleka kwePlate
Oomatshini bokuqengqa iipleyiti baqengqa amashiti esinyithi kwiisilinda ezimile kakuhle.Iintlobo ezimbini ezahlukeneyo zolu hlobo lwezixhobo zine-roller ezine kunye ne-roller ezintathu.Ngenguqu emine ye-roller, kukho i-roller ephezulu, i-pinch roller, kunye ne-side rollers.Iinguqu ezintathu ze-roller zinee-roller ezintathu ezivelisa uxinzelelo kunye neebini phezulu kunye neyodwa ezantsi.Umzobo ongezantsi ziinkqubo ezine zerola ezenza isilinda.
