Ukunemba kwe-rough noma ibalaizinsimbi zensimbiiphakeme.Ukusetshenziswa kobuchwepheshe obuthuthukisiwe kanye nemishini kungafinyelela ukusika okuncane noma kungabikho nhlobo.
Izinto zensimbi ezisetshenziswa kuukuqambakufanele ibe ne-plasticity enhle, ukuze ngaphansi kwesenzo samandla angaphandle, i-plastic deformation ingakhiqizwa ngaphandle kokuphuka. Phakathi kwezinto ezisetshenziswa kakhulu zensimbi, insimbi eyinsimbi iyimpahla ebolayo enepulasitiki empofu futhi ayikwazi ukusetshenziselwaukuqamba. Ithusi, i-aluminium nama-alloys azo ensimbi nezinsimbi ezingenayo insimbi kungenziwa ngomshini ngaphansi kwengcindezi ezindaweni ezibandayo noma ezishisayo.
Thuthukisa ukwakheka kwangaphakathi kanye nezakhiwo zemishini zokubumba insimbi engagqwali. Ingenabalaukwenza insimbikungenalutho ngemvaukuqopha ukucubungula, inhlangano yayo, ukusebenza kuyathuthukiswa futhi kuthuthukiswe,ukuqopha ukucubungulaingasusa ingaphakathi lensimbi yensimbi yokuphonsa iziphambeko ezifana nembobo yokushaywa, i-shrinkage cavity kanye nekristalu ye-dendritic, futhi ngenxa ye-deformation yensimbi ye-plastic kanye ne-recrystallization, ingenza ukuthuthukiswa okusanhlamvu okuqinile, ithole inhlangano yensimbi eminyene, ukuze kuthuthukiswe. izakhiwo zemishini ze-stainlessizinsimbi zensimbi. Ekwakhiweni kwezingxenye, uma isiqondiso samandla kanye nesiqondiso se-fiber inhlangano yezingxenye sikhethwe ngendlela efanele, ukumelana nomthelela wezingxenye kungathuthukiswa.

Izinga eliphezulu lokusetshenziswa kwezinto. Metal plastic ukwakha ikakhulukazi kuncike isikhundla isihlobo umzimba metal izicubu rearrangement, ngaphandle isidingo ukusika insimbi.
Ukukhiqiza okuphezulu.Ukucubungula ukuqambangokuvamile ukusetshenziswa komshini wokunyathelisa kanye no-fisando sokushayaukwenza ukucubungula.
Ayifaneleki insimbi engagqwali yokubumba enesimo esiyinkimbinkimbi. Forging kwakheka esimweni esiqinile, uma kuqhathaniswa cast, ukugeleza metal kulinganiselwe, ngokuvamile kudingeka ukuthatha Ukushisa nezinye izinyathelo zobuchwepheshe ukuze kuzuzwe. Kunzima ukwenza izingxenye noma ezingenalutho ezinomumo oyinkimbinkimbi, ikakhulukazi izingxenye ezinezingqimba zangaphakathi eziyinkimbinkimbi.
Ngenxa yokuthi ukubumba kunezici ezingenhla, ngakho-ke thwala umthelela noma ingcindezi eshintshanayo yezingxenye ezibalulekile (njenge-spindle yokudlulisela, iringi yegiya, induku yokuxhuma, isondo lesitimela, njll.), kufanele yenziwe ngaphandle kwebala.izinsimbi zensimbiukucubungula okungenalutho, ngakhoukuqopha ukucubungulaekwakhiweni kwemishini, ezezimayini, embonini ekhanyayo, ezimbonini ezinzima nakwezinye izimboni zisetshenziswe kakhulu.Ukuqambaingenye yezindlela eziyinhloko zokukhiqiza okungenalutho kanye nezingxenye ekukhiqizeni imishini. Ivame ukuhlukaniswaukuqamba mahhalafuthikufa ukukhohlisa.
