A ukufa kwesitampu, edla ngokubizwa ngokuba "yifa," sisixhobo esikhethekileyo esisetyenziselwa iinkqubo zokuvelisa, ngokukodwa kwintsimi yesinyithi kunye neshiti.Isetyenziselwa ukubumba, ukusika, okanye ukwenza amashiti esinyithi kwiimilo ezahlukeneyo kunye nobukhulu obunqwenelekayo.Isitampu siyafayinxalenye ebalulekileyo yenkqubo yokutywina ngentsimbi, esetyenziswa kakhulu kumashishini afana neemoto, i-aerospace, i-electronics, kunye nokuveliswa kwezixhobo zombane.

Nalu ucazululo lwemiba ephambili yokufa kwesitampu kunye nendima yayo kwinkqubo yokuvelisa:

1. Iintlobo zokufa:
   • I-Blanking Die: Isetyenziselwa ukusika isiqwenga semathiriyeli esisicaba kwiphepha elikhulu, sishiya ngasemva imilo oyifunayo.
   • Ukugqobhoza Ukufa: Kufana nokufa okungenanto, kodwa kudala umngxuma okanye imingxuma kwizinto eziphathekayo kunokusika isiqwenga esipheleleyo.
   • I-Forming Die: Isetyenziselwa ukugoba, ukugoba, okanye ukubunjwa ngokutsha kwezinto zibe yimo okanye imilo ethile.
   • I-Drawing Die: Isetyenziselwa ukutsala ishiti elisicaba lemathiriyeli ngomngxuma wokufa ukwenza imilo enomacala amathathu, njengekomityi okanye iqokobhe.
2. Amalungu eSitampu sokufa:
   • Die Block: Inxalenye ephambili yokufa ebonelela ngenkxaso kunye nokuqina.
   • I-Punch: Ilungu eliphezulu elisebenza ngamandla kwi-material ukuyisika, ukuyibumba okanye ukuyibumba.
   • I-Die Cavity: Icandelo elisezantsi elibamba izinto kwaye lichaza imilo yokugqibela.
   • I-Strippers: Amacandelo anceda ukukhulula inxalenye egqityiweyo kwi-punch emva kwe-stroke nganye.
   • Izikhonkwane zesikhokelo kunye neeBushings: Qinisekisa ukulungelelaniswa okufanelekileyo phakathi kwepunch kunye ne-die cavity.
   • Abaqhubi beenqwelo-moya: Ncedisa ulungelelwaniso oluchanekileyo lwemathiriyeli.
3. Die Operation:
   • I-die idityaniswe kunye nezinto eziza kufakwa isitampu zibekwe phakathi kwe-punch kunye nomgodi wokufa.
   • Xa i-force isetyenziswe kwi-punch, ihla ihla kwaye iqhube uxinzelelo kwizinto eziphathekayo, ibangela ukuba inqunywe, ibunjwe, okanye ibunjwe ngokoyilo lwefa.
   • Inkqubo idla ngokuqhutyelwa kwi-pressing press, enika amandla ayimfuneko kunye nokulawula ukuhamba kwepunch.
4. Die Material:
   • Iifa zenziwa ngentsimbi yesixhobo ukumelana nemikhosi kunye nokunxiba okuhambelana nenkqubo yokunyathela.
   • Ukukhethwa kwezinto zokufa kuxhomekeke kwizinto ezifana nodidi lwezinto ezifakwe isitampu, ukuntsonkotha kwenxalenye, kunye nomthamo wemveliso olindelekileyo.

I-Stamping dies idlala indima ebalulekileyo kwimveliso yobuninzi, njengoko ivumela abavelisi ukuba benze izinto ezihambelanayo, ezikumgangatho ophezulu kunye nokuhluka okuncinci.Uyilo kunye nobunjineli bokufa kwesitampu kubalulekile ukufezekisa imilinganiselo echanekileyo, ukunyamezela, kunye nokugqitywa komphezulu kwiindawo ezinesitampu.Uyilo oluncediswa yikhompyuter (CAD) kunye nezixhobo zokulinganisa zihlala zisetyenziselwa ukukhulisa uyilo lokufa ngaphambi kokuba zenziwe.

Lilonke, isitampu sokufa sisixhobo esisisiseko kwimveliso yanamhlanje, eyenza ukuveliswa ngokufanelekileyo koluhlu olubanzi lweemveliso ezivela kwiindidi ezahlukeneyo zentsimbi kunye nezinye izinto.
