Ukunyathela kuyinqubo yokukhiqiza umkhiqizo esetshenziswa abakhiqizi abaningi. Yakha insimbi ibe izingxenye ezahlukene ngendlela ehambisanayo. Inikeza umkhiqizi indlela eqondile kakhulu yokulawula inqubo yokukhiqiza futhi isetshenziswa kabanzi ezindaweni ezahlukene zokukhiqiza kwezimboni ngenxa yezinketho eziningi ezitholakalayo.
Lokhu kuguquguquka kusho ukuthi abakhiqizi banolwazi oluningi ngezindlela ezahlukene zokunyathela, ngakho-ke kunengqondo ukusebenza nomhlinzeki wezinto ezinolwazi. Uma usebenza ngezinsimbi ezifana ne-aluminium noma insimbi engagqwali, kubalulekile ukuqonda ukusetshenziswa kwe-alloy enqubweni ngayinye, futhi kuyiqiniso nangokunyathela.
Izindlela ezimbili ezivamile zokunyathela yi-progressive die stamping kanye ne-transfer die stamping.
Kuyini ukunyathela?
Ukunyathela kuyinqubo ehilela ukubeka ishidi lensimbi eliyisicaba kumshini wokunyathela. Izinto zokuqala zingaba ngesimo se-billet noma se-coil. Insimbi bese ikhiwa ibe yisimo esifiselekayo kusetshenziswa i-stamping die. Kunezinhlobo eziningi ezahlukene zokunyathela ezingasetshenziswa kushidi lensimbi, okuhlanganisa ukubhoboza, ukumboza, ukugoba, ukubhoboza, ukubhoboza, kanye nokumboza.
Kwezinye izimo, umjikelezo wokunyathela wenziwa kanye kuphela, okwanele ukudala isimo esiqediwe. Kwezinye izimo, inqubo yokunyathela ingase yenzeke ngezigaba eziningana. Inqubo ivame ukwenziwa ensimbini ebandayo kusetshenziswa amadayi akhiwe ngomshini aqondile enziwe ngensimbi yamathuluzi esebenza kahle ukuqinisekisa ukufana nokuthembeka kwenqubo yokunyathela.
Ukwakhiwa kwensimbi okulula kwaqala ezinkulungwaneni zeminyaka futhi ekuqaleni kwakwenziwa ngesandla kusetshenziswa isando, i-awl, noma amanye amathuluzi anjalo. Ngokufika kwezimboni kanye nokwenza izinto ngokuzenzakalela, izinqubo zokunyathela ziye zaba yinkimbinkimbi futhi zahlukahluka ngokuhamba kwesikhathi, zinezinketho eziningi ongakhetha kuzo.
Kuyini ukunyathela nge-die okuqhubekayo?
Uhlobo oludumile lokunyathela lwaziwa ngokuthi ukunyathela okuqhubekela phambili, okusebenzisa uchungechunge lwemisebenzi yokunyathela enqubweni eyodwa eqondile. Insimbi iphakelwa kusetshenziswa uhlelo oluyisunduzela phambili esiteshini ngasinye lapho umsebenzi ngamunye odingekayo wenziwa khona isinyathelo ngesinyathelo kuze kube yilapho ingxenye isiqediwe. Isenzo sokugcina ngokuvamile umsebenzi wokucheba, ohlukanisa umsebenzi wokusebenza nolunye uhlobo lwezinto. Amakhoyili avame ukusetshenziswa njengezinto zokusetshenziswa zemisebenzi yokunyathela okuqhubekela phambili, njengoba evame ukusetshenziswa ekukhiqizweni okuphezulu.
Imisebenzi yokunyathela ngodayi eqhubekayo ingaba yizinqubo eziyinkimbinkimbi ezihilela izinyathelo eziningi ngaphambi kokuba ziqedwe. Kubalulekile ukuqhubekisela phambili ishidi ngendlela eqondile, ngokuvamile ngaphakathi kwengxenye eyodwa kweziyikhulu zamasentimitha. Iziqondiso ezithambile zengezwe emshinini futhi zihlangana nezimbobo ezazibhotshozwe ngaphambilini ensimbini ukuqinisekisa ukuhambisana okufanele ngesikhathi sokudla.
Uma iziteshi eziningi zihilelekile, inqubo ibiza kakhulu futhi idla isikhathi; ngenxa yezizathu zomnotho kunconywa ukuklama ama-die ambalwa aqhubekayo ngangokunokwenzeka. Kubalulekile ukuqaphela ukuthi uma izici zisondelene kungase kungabi khona indawo eyanele yokushaya. Futhi, izinkinga ziyavela lapho ama-cutout nama-protrusions emancane kakhulu. Iningi lalezi zinkinga liyaxazululwa futhi likhokhelwa ngokusebenzisa isofthiwe ye-CAD (Computer Aided Design) ngokwengxenye kanye nomklamo wesikhunta.
Izibonelo zezinhlelo zokusebenza ezisebenzisa ama-progressive dies zifaka phakathi iziphetho zamathini eziphuzo, izimpahla zemidlalo, izingxenye zomzimba wezimoto, izingxenye zezindiza, izinto zikagesi zabathengi, ukupakishwa kokudla, nokuningi.
Kuyini i-Transfer Die Stamping?
Ukunyathelisa ngedayi yokudlulisa kufana nokunyathelisa ngedayi yokudlulisa okuqhubekayo, ngaphandle kokuthi umsebenzi udluliselwa ngokomzimba kusuka esiteshini esisodwa kuya kwesinye kunokuba uqhubeke njalo. Lena indlela enconywayo yokusebenza okuyinkimbinkimbi okubandakanya izinyathelo eziningi eziyinkimbinkimbi. Izinhlelo zokudlulisa ezizenzakalelayo zisetshenziselwa ukuhambisa izingxenye phakathi kwezindawo zokusebenza nokubamba imihlangano endaweni ngesikhathi sokusebenza.
Umsebenzi wesikhunta ngasinye ukubumba ingxenye ngendlela ethile ize ifinyelele ubukhulu bayo bokugcina. Imishini yokucindezela yeziteshi eziningi ivumela umshini owodwa ukuthi usebenzise amathuluzi amaningi ngesikhathi esisodwa. Eqinisweni, njalo lapho umshini wokucindezela ucinywa njengoba umsebenzi udlula kuwo, uhilela wonke amathuluzi asebenza ngesikhathi esisodwa. Ngokuzenzakalelayo kwesimanje, imishini yokucindezela yeziteshi eziningi manje ingenza imisebenzi okungenzeka ukuthi yayihilela imisebenzi eminingana ehlukene ekucindezeleni okukodwa.
Ngenxa yobunzima bazo, ama-transfer punch avame ukuhamba kancane kunezinhlelo ze-progressive die. Kodwa-ke, ezingxenyeni eziyinkimbinkimbi, kufaka phakathi zonke izinyathelo enqubweni eyodwa kungasheshisa inqubo yokukhiqiza iyonke.
Izinhlelo zokunyathela nge-die stamping zivame ukusetshenziselwa izingxenye ezinkulu kunezifanele inqubo yokunyathela nge-die stamping eqhubekayo, kufaka phakathi ozimele, amagobolondo kanye nezingxenye zesakhiwo. Ngokuvamile kwenzeka ezimbonini ezisebenzisa amasu okunyathela nge-die stamping eqhubekayo.
Indlela yokukhetha izinqubo ezimbili
Ukukhetha phakathi kwalokhu okubili kuvame ukuncika ekusetshenzisweni okuthile. Izici okumele zicatshangelwe zifaka phakathi ubunzima, usayizi kanye nenani lezingxenye ezihilelekile. Ukunyathelisa ngodayi okuqhubekela phambili kulungile lapho kucutshungulwa inani elikhulu lezingxenye ezincane ngesikhathi esifushane. Izingxenye ezinkulu neziyinkimbinkimbi ezihilelekile, kulapho kuzodingeka khona ukunyathelisa ngodayi okuqhubekela phambili. Ukunyathelisa ngodayi okuqhubekela phambili kuyashesha futhi kuyonga, kuyilapho ukunyathelisa ngodayi okuqhubekela phambili kunikeza ukuguquguquka okukhulu kanye nokuhlukahluka.
Kunezinye izinkinga ezimbalwa zokunyathela nge-progressive die stamping abakhiqizi okudingeka baziqaphele. Ukunyathela nge-progressive die stamping ngokuvamile kudinga ukufakwa okwengeziwe kwezinto zokusetshenziswa. Amathuluzi nawo ayabiza kakhulu. Awakwazi futhi ukusetshenziselwa ukwenza imisebenzi edinga izingxenye ukuze zishiye inqubo. Lokhu kusho ukuthi kweminye imisebenzi, njengokugoqa, ukugoqa intamo, ukugoqa i-flange, ukugoqa intambo noma ukugoqa okujikelezayo, inketho engcono ukunyathela nge-transfer die.
