Iyini Ukuhlukaniswa Okuyisisekelo Kokwakha?

Ukwakha kuyinqubo eyisisekelo yokwakha insimbi edlala indima ebalulekile ekukhiqizeni izingxenye eziqinile nezihlala isikhathi eside kuzo zonke izimboni. Kusukela kuma-crankshaft ezimoto kanye nama-bracket ezindiza kuya kuma-fasteners okwakha kanye namathuluzi e-oyela, izingxenye ezibunjiwe zaziwa ngezakhiwo zazo ezinhle kakhulu zemishini kanye nobuqotho besakhiwo.

Ukuqondaukuhlukaniswa okuyisisekelo kokwakhakusiza onjiniyela, abaklami, kanye nochwepheshe bokuthenga ukuthi bakhethe indlela efanele kakhulu yokuthunga ngokusekelwe ekusetshenzisweni, ubunzima bezingxenye, umthamo wokukhiqiza, kanye nohlobo lwezinto ezibonakalayo. Lesi sihloko sihlola izinhlobo eziyinhloko zokuthunga kanye nezici zazo ukuze sikusize wenze izinqumo ezinolwazi.

Kuyini Ukwakha?

Ukwakhainqubo yokukhiqiza ehilela ukubumba insimbi kusetshenziswa amandla okucindezela asendaweni. Lokhu kungenziwa ngokubhoboza, ukucindezela, noma ukugoqa—ngokuvamile ngensimbi isesimweni esishisayo (kodwa esiqinile). Ukwakha kuthuthukisa isakhiwo sangaphakathi sezinhlamvu, kuthuthukisa amandla, futhi kususa amaphutha afana nokugoba noma ukufakwa.

Ukwakha kuguqukele kumasu ahlukahlukene kuye ngezici ezifana nokushisa, imishini esetshenzisiwe, kanye nokucushwa kwedayi.

Ukuhlukaniswa Okuyisisekelo Kokwakha

Izinqubo zokwakha zingahlukaniswa kabanzi ngokusekelwe ku-izindlela ezimbili eziyinhloko:

1. Ukushisa Okwakhayo

2. Ukucushwa Kwe-Die kanye Nokusebenzisa Amathuluzi

Ake sibheke ukuhlukaniswa ngakunye ngokuningiliziwe.

Ukuhlukaniswa Ngokubumba Izinga Lokushisa

Lena yindlela evame kakhulu yokuhlukanisa izinqubo zokubumba ngezigaba. Kuye ngokushisa lapho kwenziwa khona ukubumba, kuhlukaniswe kanje:

1. Ukwakha Okushisayo

Incazelo: Kwenziwa emazingeni okushisa aphezulu, ngokuvamile ngaphezu kwezinga lokushisa lokuphinda kusetshenziswe kwensimbi (cishe u-1100–1250°C wensimbi).

Izinzuzo:

• Ukuqina okuphezulu kanye nokumelana okuphansi kokuguquguquka

• Ivumela izimo eziyinkimbinkimbi

• Ihlunga isakhiwo sokusanhlamvu

• Iqeda ukugoba kanye nokukhubazeka

Ukungalungi:

• Ukwakheka kwesikali ngenxa ye-oxidation

• Ukunemba kobukhulu kungaphansi kokwakhiwa okubandayo

• Kudinga amandla engeziwe okushisa

Izicelo:

• Izingxenye zezimoto (ama-crankshaft, amagiya)

• Izingxenye zemishini esindayo

• Imigodi yezimboni kanye nama-flange

2. Ukwakha Okufudumele

Incazelo: Kwenziwa emazingeni okushisa aphakathi nendawo (phakathi kuka-500°C no-900°C), kuhlanganisa izinzuzo ezithile zokufakelwa okushisayo nokubandayo.

Izinzuzo:

• Imithwalo yokwakha encishisiwe

• Ukulawulwa kobukhulu okuthuthukisiwe

• I-oxidation encane uma iqhathaniswa nokushisa

• Ukuqeda okungcono kobuso

Ukungalungi:

• Kunqunyelwe ezintweni ezithile

• Izidingo zemishini eziyinkimbinkimbi kakhulu

Izicelo:

• Izingxenye zokudlulisa

• Imijaho yamabhere

• Izikhala zegiya

3. Ukwakha Okubandayo

Incazelo: Kwenziwa ezingeni lokushisa legumbi noma eduze kwalo ngaphandle kokushisa impahla.

Izinzuzo:

• Ukuqeda okuphezulu kakhulu

• Ukubekezelelana okuseduze

• Ukuqinisa umsebenzi kuthuthukisa amandla

• Akukho ukushiswa noma ukukala

Ukungalungi:

• Kudingeka amandla amakhulu okwakha

• Kunqunyelwe ezimweni ezilula kanye nezinto ezithambile

• Ingozi yokucindezeleka okusele

Izicelo:

• Izibambo (amabhawodi, izikulufo, ama-rivets)

• Ama-Shaft

• Izingxenye ezincane zokunemba

Ukuhlukaniswa Ngokucushwa Kokufa

Ukwakha kungahlukaniswa futhi ngokususelwa kuhlobo lwamadayi kanye nemishini esetshenziswa kule nqubo:

1. I-Open Die Forging (Ukwakha Kwamahhala)

IncazeloInsimbi ibekwa phakathi kwezinto eziyisicaba noma ezilula ezingayivali ngokuphelele impahla.

Inqubo:

• Umsebenzi wokusebenza ukhubazekile ngezinyathelo eziningi

• Umsebenzisi ulawula isiqondiso sokuguqulwa

• Kuhle kakhulu ekukhiqizweni okwenziwe ngokwezifiso noma okuphansi

Izinzuzo:

• Ifanele izimo ezinkulu nezilula

• Izindleko eziphansi ze-die

• Ukulawula okuhle kokugeleza kokusanhlamvu

Ukungalungi:

• Ukunemba okuphansi

• Kudingeka abasebenzi abanamakhono engeziwe

• Kungadingeka imishini eyengeziwe

Izicelo:

• Ama-shaft amakhulu, amadiski, amasongo

• Izingxenye zezimboni ezisindayo

• Izingxenye zasolwandle nezokukhiqiza ugesi

2. I-Die Forging Evaliwe (I-Impression Die Forging)

Incazelo: Insimbi ifakwa emgodini wedayi ofana nesimo esifunwayo sengxenye.

Inqubo:

• Amandla okucindezela okuphezulu aphoqa insimbi ukuthi ingene edayeleni

• I-Flash ivame ukwakheka bese inqunywa

• Kuhle kakhulu ekukhiqizweni okuphezulu

Izinzuzo:

• Izingxenye eziqondile, ezicishe zibe yi-net

• Ukuphindaphinda okuphezulu kanye nokusebenza kahle

• Izakhiwo zemishini ezithuthukisiwe ngenxa yokulungiswa kokusanhlamvu

Ukungalungi:

• Izindleko eziphezulu zokusebenzisa amathuluzi

• Kunqunyelwe ezingxenyeni ezincane neziphakathi nendawo

• Kudinga imishini eyinkimbinkimbi kakhulu

Izicelo:

• Amagiya

• Izinduku zokuxhuma

• Izingxenye zezimoto nezindiza

3. Ukwakhiwa Okucasulayo

Incazelo: Kuhilela ukwandisa ububanzi bengxenye yebha yensimbi ngokucindezela ubude bayo.

Inqubo:

• Ngokuvamile kwenziwa emishinini yokwakha evundlile

• Kusetshenziswa ukwakha amakhanda kuma-bolts, ama-rivets, kanye nama-fasteners

Izinzuzo:

• Ukukhiqizwa okuphumelelayo kwezingxenye ezilinganayo

• Amandla amahle omshini

• Isivinini sokukhiqiza esiphezulu

Izicelo:

• Amabholti

• Izikulufu

• Imigodi kanye neziqu ze-valve

4. Ukugoqa Indandatho Okungenamthungo

Incazelo: Uhlobo oluthile lokwakha lapho indandatho yakhiwa khona nge-preform ebhoboziwe bese inwetshwa ngokugingqa.

Izinzuzo:

• Ukuqondiswa okuhle kakhulu kokusanhlamvu

• Ubukhulu bodonga obuqondile

• Isebenza kahle kakhulu kumasongo amakhulu

Izicelo:

• Amabheringi

• Ama-Flanges

• Izingxenye zegiya kanye nezitsha zokucindezela

Ukuhlukaniswa Okwengeziwe

Ekwakheni kwesimanje, izinqubo nazo zihlukaniswa ngokuthi:

a. Uhlobo Lomshini

• Ukwakha ngesando

• Ukwakhiwa kwemishini yokucindezela ye-hydraulic

• Ukwakhiwa kwe-screw press

• Ukwakhiwa kwemishini yokucindezela

b. Izinga Lokuzenzakalela

• Ukwakha ngesandla

• Ukwakha okuzenzakalelayo

• Ukwakha okuzenzakalelayo ngokugcwele

c. Uhlobo Lwezinto

• Insimbi (insimbi yekhabhoni, insimbi engagqwali)

• Okungewona amaminerali (i-aluminium, ithusi, i-titanium, i-nickel alloys)
