Inqubo Yokukhiqiza Eqhubekayo

Ishubhu eligoqayo eliqhubekayo (ngemuva kwalokhu elibizwa ngokuthi i-MPM) inqubo i-mandrel ibhekisela ekugqokeni ikholomu ende ye-capillary ngokuqhubekayo ngokusebenzisa i-rack yokuhleleka yochungechunge, indlela yokugoqa kanye nokuginqika evumelana nokuba yizidingo zosayizi wepayipi likamama.Isici sawo esihlukanisayo umthamo omkhulu, ukusebenza kahle okuphezulu, ubude bepayipi elingenalutho eligoqayo kanye nekhwalithi yomkhiqizo, ububanzi bosayizi omkhulu;kodwa ukutshalwa kwezimali kwayo okukhulu kanye nobuchwepheshe obuhlobene nokulawula okuzenzakalelayo kufuna kakhulu.

I-MPM rack yohlobo lwamaroli amabili, isakhiwo esifana kakhulu nesigayo esigoqa kabili esivamile.Kuye ngokuhamba kwe-mandrel MPM ingahlukaniswa ibe yi-full-floating kanye ne-semi stopper stopper mandrel mill izinhlobo ezintathu.

1970s ngaphambi MPM sebenzisa full-floating mandrel operation.Kusukela Punch ukungena capillary ngemva mandrel singene ipayipi rolling umshini rolling, rolling lapho rolling aphume esigayweni ingemuva ukudonsa emuva rollers mandrel, kukhona bar off umshini kusukela rolling mandrel ilungu ihoxisiwe, rolling singene isinyathelo esilandelayo, futhi wabuyela mandrel isigayo reception ngemva kokupholisa, faka kabusha umjikelezo womsebenzi olandelayo.

1970s France and Italy ziye zavela mandrel isigamu isitobha kanye isitobha of MPM.Ngamafuphi, lezi zindlela ezimbili zokusebenza emshinini wokugoqa we-mandrel, zibolekwa endleleni ye-mandrel yokusebenza komshini wokugoqa ama-roll amathathu.

Indlela yokusebenza ye-mandrel egcinwe isigamu, isendleleni yokugoqa, isivinini sokunyakaza kwe-mandrel sinqunyelwe, isibambi sekhadi mandrel siboshelwe ngaphansi kwejubane eligoqiwe langaphambili le-workpiece.Agcinwe mandrel indlela yokusebenza, ngaphandle ngesikhathi rolling, isivinini mandrel ukunyakaza kulinganiselwe, uthayi usuqedile ngemva kweqa, mandrel umnikazi ikhadi idonswe emuva emsebenzini ukuqala isikhundla.

Eminyakeni yamuva, i-MPM emise okwesithathu engu-Y enezimpawu ze-PQF, ilandele ubuchwepheshe bokunciphisa ukungezwani kusuka ku-roller yesibili kuya kwezinguquko ezintathu ze-roller, ngakho-ke inqubo yokugudluza izimo zokuguqulwa kokucindezeleka nokusatshalaliswa kokuguqulwa, imishini, ukusatshalaliswa komthwalo wemishini kagesi, ukujiya odongeni ukujiya nokubekezelela ukushuba futhi kanjalo has a ezimbili-roll isigayo izinzuzo ezingenakuqhathaniswa.Inqubo yayo eqinile yokugingqika ingathuthukiswa ubukhulu bepayipi eliphambanayo, indawo ephansi ye-flange noma ukwenzeka kwe-Lin Wen emkhakheni wamapayipi anezindonga ezincanyana kanye nepayipi le-alloy eligingqikayo eliguquguqukayo futhi linomnotho.
