Isikhunta, ukubunjwa okuhlukahlukene namathuluzi asetshenziswa ekukhiqizeni izimboni ukuthola umkhiqizo owufunayo ngomjovo,vuthela ukubumba, i-extrusion, i-die-casting noma i-forging, i-casting, i-stamping, njll. Ngamafuphi, isikhunta iyithuluzi elisetshenziselwa ukukhiqiza i-athikili ebunjiwe, ithuluzi elakhiwe izingxenye eziningana, ukubunjwa okuhlukene kwenziwa izingxenye ezahlukene.Isetshenziswa kakhulu ukucubungula umumo we-athikili ngokushintsha isimo somzimba sezinto ezibunjwayo.

Ngakho-ke isikhunta senziwe kanjani?
Okulandelayo isingeniso esifushane senqubo yokukhiqiza isikhunta yesimanje.

1, ESI (EarlierSupplierInvolvement umhlinzeki ukuzibandakanya kusenesikhathi): Lesi sigaba ngokuyinhloko yingxoxo yezobuchwepheshe phakathi kwamakhasimende nabaphakeli mayelana nokwakhiwa komkhiqizo nokuthuthukiswa kwesikhunta, njll. Injongo eyinhloko iwukuvumela abahlinzeki baqonde ngokucacile inhloso yomklamo womklami womkhiqizo kanye nezidingo zokunemba, futhi vumela abaklami bomkhiqizo bakuqonde kangcono ukukhiqizwa kwesikhunta Injongo eyinhloko iwukuvumela umphakeli ukuthi aqonde ngokucacile inhloso yomklamo womklami womkhiqizo kanye nezidingo zokunemba, kanye nokuvumela umklami womkhiqizo aqonde kangcono ikhono lokukhiqiza isikhunta kanye nokusebenza kwenqubo yomkhiqizo, ukuze enze design enengqondo kakhudlwana.

2, I-Quotation: Kubandakanya intengo yesikhunta, impilo yesikhunta, inqubo yokwenza inzuzo, inani lamathani adingwa umshini kanye nesikhathi sokulethwa kwesikhunta.(Ikhotheshini enemininingwane eminingi kufanele ifake ulwazi olufana nosayizi womkhiqizo nesisindo, usayizi wesikhunta nesisindo, njll.)

3, I-oda (PurchaseOrder): I-oda lekhasimende, idiphozithi ekhishiwe kanye ne-oda lomphakeli lamukelwe.

4、ProductionPlanningandScheduleArrangement:Lesi sigaba sidinga ukuphendula ikhasimende ngosuku oluthile lokulethwa kwesikhunta.

5,Isikhunta Design:Pro/Engineer, UG, Solidworks, AutoCAD, CATIA, njll. kukhona isoftware yokuklama okungenzeka.

6, Ukuthengwa kwezinto zokwakha

I-7, ukucubungula isikhunta (Machining): izinqubo ezihilelekile zicishe ziphenduke, i-gong (ukugaya), ukwelashwa kokushisa, ukugaya, i-computer gong (CNC), ukukhishwa kukagesi (EDM), ukusika izintambo (WEDM), ukuhlanganisa ukugaya (JIGGRINGING), i-laser ukuqopha, ukupholisha, njll.

8. Ukuhlangana kwesikhunta (Umhlangano)

9. Isivivinyo sesikhunta (TrialRun)

Isikhuntaukwenza

Izidingo zokuklama isikhunta kanye nokukhiqizwa yilezi: ubukhulu obunembile, izindawo ezihlanzekile, ukwakheka okunengqondo, ukusebenza kahle kokukhiqiza okuphezulu, ukuzenzela okulula, ukukhiqiza okulula, ubude besikhathi eside bempilo, izindleko eziphansi, ukuklama ukuhlangabezana nezidingo zenqubo kanye nokuba nengqondo kwezomnotho.

Ukuklanywa kwesakhiwo sesikhunta kanye nokukhethwa kwamapharamitha kufanele kucabangele izici ezinjengokuqina, isiqondiso, indlela yokuthulula, indlela yokufaka kanye nosayizi wokukhipha.Izingxenye ezigugile zesikhunta kufanele kube lula ukuzishintsha.Ezibunjeni zepulasitiki kanye nezibunjwa zokubunjwa, kufanele kucatshangelwe uhlelo lokuthulula olunengqondo, ukugeleza kwepulasitiki encibilikisiwe noma insimbi, indawo kanye nesiqondiso sokungena emgodini.Ukuze kwandiswe ukukhiqiza futhi kuncishiswe ukulahlekelwa okuthululwayo kubagijimi, isikhunta se-multi-cavity singasetshenziswa, lapho imikhiqizo eminingana efanayo noma ehlukene ingaqedwa ngesikhathi esisodwa kusikhunta esisodwa.Ekukhiqizeni ngobuningi, ukusebenza okuphezulu, ukunemba okuphezulu kanye nesikhunta sempilo ende kufanele sisetshenziswe.

Isikhunta seziteshi eziningi esiqhubekayo kufanele sisetshenziselwe ukugxiviza, futhi isikhunta se-carbide block esiqhubekayo singasetshenziswa ukwandisa impilo yesevisi.Ekukhiqizweni kweqoqo elincane kanye nokukhiqizwa kwesivivinyo kwemikhiqizo emisha, isikhunta esinesakhiwo esilula, isivinini sokukhiqiza esisheshayo kanye nezindleko eziphansi kufanele kusetshenziswe, njengokubunjwa okuhlanganisiwe kokubhoboza, ukubunjwa kwepuleti elincanyana lokubhoboza, isikhunta senjoloba ye-polyurethane, isikhunta se-alloy point ephansi, isikhunta sengxubevange ye-zinc. kanye nesikhunta se-super plasticity alloy.Isikhunta sesiqalile ukusebenzisa i-computer-aid design (CAD), okungukuthi ngokusebenzisa isethi yezinhlelo ezigxile kukhompuyutha ukuze kuthuthukiswe ukwakheka kwezibunjwa.Lesi yisiqondiso sokuthuthukiswa komklamo wesikhunta.

Ngokwezici zesakhiwo, ukwakhiwa kwesikhunta kuhlukaniswe ngokubhoboza okuyisicaba kanye nokusika isikhunta kanye nesikhunta se-cavity esinesikhala.Ukubhoboza kanye nokusika amafa kusebenzisa ukulungiswa okunembayo kwe-convex futhi i-concave iyafa, okunye ngisho nokulungisa okungenazikhala.Okunye ukufa kokubumba, njengokufa okubandayo, ukufa kwe-casting, i-powder metallurgy dies, ipulasitiki iyafa kanye ne-rubber dies i-cavity dies, esetshenziselwa ukwakha izingxenye ezintathu-ntathu.Izibungu ze-Cavity zinezidingo zobukhulu ezinkomba ezi-3: ubude, ububanzi nokuphakama, futhi ziyinkimbinkimbi ngokwakheka futhi kunzima ukuzikhiqiza.Isikhunta ngokuvamile sikhiqizwa ngamaqoqo amancane futhi ngezingxenye ezilodwa.Izidingo zokukhiqiza ziqinile futhi zinembile futhi zisebenzisa imishini yokulinganisa enembayo nemishini.

I-flat dies ekuqaleni ingakhiwa nge-electro-etching bese yanda ngokwengeziwe ngokunemba nge-contour kanye nokuhlanganisa ukugaya.Ukugaya umumo kungenziwa ngemishini yokugaya ijika le-optical projection noma imishini yokugaya engaphezulu enemishini yokugaya namasondo okubuyisela, noma ngamathuluzi okugaya umumo okhethekile emishinini yokugaya engaphezulu.Imishini yokugaya edidiyelwe ingasetshenziswa ukuze kumiswe isikhunta ngendlela enembile ukuze kuqinisekiswe ukuthi amabanga alungile abhorekile kanye nokuvuleka.Imishini yokugaya elawulwa ngamanani ekhompyutha (CNC) eqhubekayo ye-orbital ingasetshenziswa futhi ukugaya noma yiziphi isikhunta esigobile nesingenalutho.Izibungu ze-cavity ezingenalutho zenziwe ngomshini ngokugaya i-contour, i-EDM kanye ne-electrolytic machining.Ukusetshenziswa okuhlangene kwephrofayili ye-contour kanye nobuchwepheshe be-CNC, kanye nokwengezwa kwekhanda eliyisicaba eliqondiswe kathathu ku-EDM, kungathuthukisa ikhwalithi yomgodi.Ukwengezwa kwe-electrolysis efuthayo kumishini ye-electrolytic kungakhuphula umkhiqizo.
