Ukuvala kuyinqubo yokugxiviza esebenzisa idayi ukuze ahlukanise amashidi kwelinye.Ukungasho lutho kubhekisela ekuthuleni nasekushayeni ngesibhakela.Ingxenye yokubhoboza noma yenqubo eshaya umumo oyifunayo eshidini eduze kwekhonta evaliwe ibizwa ngokuthi i-blanking, futhi imbobo ebhoboza umumo oyifunayo kusukela engxenyeni yenqubo ibizwa ngokuthi ukubhoboza.
Ukungasho lutho kungenye yezinqubo eziyisisekelo kakhulu enqubweni yokugxiviza.Ayikwazi ukubhoboza ngokuqondile izingxenye eziqediwe, kodwa futhi ilungise izikhala zezinye izinqubo ezinjengokugoba, ukudweba okujulile nokwakheka, ngakho-ke isetshenziswa kabanzi ekucubunguleni isitembu.
Ukungasho lutho kungahlukaniswa izigaba ezimbili: ukuvala okuvamile nokuvala kahle.Ukuvala okuvamile kuqaphela ukuhlukaniswa kwamashidi ngendlela yokuqhekeka kwe-shear phakathi kwe-convex ne-concave iyafa;ukuvala kahle kuqaphela ukuhlukaniswa kwamashidi ngendlela ye-plastic deformation.
Inqubo ye-deformation engenalutho icishe ihlukaniswe yaba izigaba ezintathu ezilandelayo: 1. Isigaba sokuguga nokunwebeka;2. Isiteji sokuguqulwa kwepulasitiki;3. Isiteji sokuhlukaniswa kwe-fracture.
Ikhwalithi yengxenye engenalutho ibhekisela esimweni se-cross-sectional, ukunemba kobukhulu kanye nephutha lomumo wengxenye engenalutho.Ingxenye yengxenye engenalutho kufanele ibe mpo futhi ibushelelezi ngangokunokwenzeka ngama-burrs amancane;ukunemba kobukhulu kufanele kuqinisekiswe ukuthi kungaphakathi kwebanga lokubekezelelana elicaciswe emdwebeni;ukuma kwengxenye engenalutho kufanele kuhlangabezane nezidingo zomdwebo, futhi indawo engaphezulu kufanele ibe mpo ngangokunokwenzeka.
Kunezici eziningi ezithinta ikhwalithi yezingxenye ezingenalutho, ikakhulukazi ezihlanganisa izakhiwo zezinto ezibonakalayo, usayizi wegebe nokufana, ukucija konqenqema, ukwakheka kwesikhunta kanye nesakhiwo, ukunemba kwesikhunta, njll.
Ingxenye yengxenye engenalutho ikhombisa ngokusobala izindawo ezine okuyizici, okuwukudilika, indawo ebushelelezi, indawo emagebhugebhu kanye ne-burr.Ukuzijwayeza kubonise ukuthi lapho unqenqema lwe-punch lubuthuntu, kuzoba nama-burrs asobala ekugcineni kwengxenye engenalutho;lapho unqenqema lokufa kwensikazi lubuthuntu, kuzoba nama-burrs asobala ekugcineni kwembobo yengxenye yokubhoboza.
Ukunemba kwe-dimensional kwengxenye engenalutho ibhekisela kumehluko phakathi kosayizi wangempela wengxenye engenalutho kanye nosayizi oyisisekelo.Umehluko omncane, ukhuphuka nokunemba.Kunezici ezimbili ezinkulu ezithinta ukunemba kobukhulu bezingxenye ezingenalutho: 1. Isakhiwo kanye nokunemba kokukhiqiza kokushaya ngesibhakela;2. Ukuchezuka kwengxenye engenalutho ngokuhlobene nobukhulu be-punch noma kufa ngemva kokuqedwa kokushaya.
Iphutha lomumo lezingxenye ezingenalutho lisho iziphambeko ezifana nokugoqa, ukusonteka, nokuguqulwa, futhi izici ezinomthelela ziyinkimbinkimbi.Ukunemba kwezomnotho okungafinyelelwa ngezingxenye ezivamile zensimbi ezingenalutho yi-IT11~IT14, futhi ephakeme kakhulu ingafinyelela kuphela ku-IT8~IT10.
