A ukufa isitembu, evame ukubizwa ngokuthi "i-die," iyithuluzi elikhethekile elisetshenziswa ezinqubweni zokukhiqiza, ikakhulukazi emkhakheni wokusebenza kwensimbi kanye nokwakhiwa kweshidi lensimbi.Isetshenziselwa ukubumba, ukusika, noma ukwakha amashidi ensimbi abe amajamo nosayizi abafiselekayo abahlukahlukene.Ukunyathela kuyafaziyingxenye ebalulekile yenqubo yokugxiviza kwensimbi, esetshenziswa kakhulu ezimbonini ezifana nezezimoto, i-aerospace, electronics, kanye nokukhiqiza izinto zikagesi.

Nakhu ukuhlukaniswa kwezici ezibalulekile zefa lokugxiviza kanye nendima yalo enqubweni yokukhiqiza:

1. Izinhlobo ze-Die:
   • I-Blanking Die: Isetshenziselwa ukusika ucezu lwempahla eyisicaba eshidini elikhudlwana, ishiye umumo oyifunayo.
   • Ukubhoboza Die: Kufana nefa elingenalutho, kodwa lidala imbobo noma izimbobo kumpahla kunokusika ucezu oluphelele.
   • I-Forming Die: Isetshenziselwa ukugoba, ukugoqa, noma ukubumba kabusha impahla ibe yifomu noma umumo othize.
   • I-Drawing Die: Isetshenziselwa ukudonsa ishidi lezinto eziyisicaba endaweni yokufa ukuze kwakhiwe umumo onezinhlangothi ezintathu, njengenkomishi noma igobolondo.
2. Izingxenye ze-Stamping Die:
   • I-Die Block: Ingxenye eyinhloko yedayizi ehlinzeka ngokusekela nobuqinile.
   • I-Punch: Ingxenye engaphezulu esebenza ngamandla entweni ukuyisika, ukuyibumba, noma ukuyibumba.
   • I-Die Cavity: Ingxenye engezansi ebamba into futhi ichaza umumo wokugcina.
   • Ama-Strippers: Izingxenye ezisiza ukukhulula ingxenye eqediwe ku-punch ngemva kokushaywa ngakunye.
   • Izikhonkwane Zokuqondisa kanye Nezihlahla: Qinisekisa ukuhleleka okufanele phakathi kwe-punch kanye ne-die cavity.
   • Abashayeli bezindiza: Basiza ekuqondaneni okunembile kwezinto.
3. I-Die Operation:
   • Idayizi ihlanganiswa nento ezogxivizwa ibekwe phakathi kwepunch kanye nembobo yokufa.
   • Uma kusetshenziswa amandla esibhakeleni, siya phansi futhi sisebenzisa ingcindezi ezintweni, okubangela ukuba sisikwe, silolongeke, noma sakheke ngokuhambisana nesakhiwo sedayizi.
   • Inqubo ngokuvamile yenziwa emshinini wokunyathelisa, ohlinzeka ngamandla adingekayo futhi ulawule ukunyakaza kwe-punch.
4. I-Die Material:
   • Ama-dies ngokuvamile enziwa ngensimbi yamathuluzi ukumelana namandla nokuguga okuhambisana nenqubo yokugxiviza.
   • Ukukhethwa kwezinto ezifayo kuncike ezintweni ezifana nohlobo lwento egxivizwayo, ubunkimbinkimbi bengxenye, kanye nevolumu yokukhiqiza elindelekile.

Ukufa kwesitembu kudlala indima ebalulekile ekukhiqizweni ngobuningi, njengoba kuvumela abakhiqizi ukuthi bakhe izingxenye ezingaguquki, zekhwalithi ephezulu ezinokuhlukahluka okuncane.Idizayini nobunjiniyela bokufa kwesitembu kubalulekile ukuze kuzuzwe ubukhulu obunembile, ukubekezelela, kanye nokuqedwa kwendawo ezingxenyeni ezinesitembu.Idizayini esizwa ngekhompyutha (i-CAD) namathuluzi okulingisa avame ukusetshenziswa ukuze kuthuthukiswe imiklamo efayo ngaphambi kokuthi yenziwe.

Sekukonke, ukugxiviza kuyafa kuyithuluzi eliyisisekelo ekukhiqizeni kwesimanje, okuvumela ukukhiqizwa okuphumelelayo kwezinhlobonhlobo zemikhiqizo evela ezinhlotsheni ezahlukahlukene zeshidi lensimbi nezinye izinto.
