Nguwuphi uMahluko phakathi kweCasting kunye neForging?

Xa kuziwa ekusebenzeni kwesinyithi kunye nokuvelisa,ukuphosakwayeukwenzaziinkqubo ezimbini ezisisiseko ezisetyenziselwa ukubumba isinyithi sibe ngamacandelo asebenzayo. Zombini ezi ndlela zineengenelo kunye nezingeloncedo kuzo kwaye zilungele usetyenziso olwahlukileyo, indawo ezingqongileyo, kunye nolindelo lokusebenza.

Ukuqonda iiyantlukwano phakathi kokubunjwa kunye nokukhwabanisaibalulekile kwiinjineli, iingcali zokuthengwa kwempahla, kunye nabaphathi beprojekthi abafuna ukukhetha inkqubo efanelekileyo yokuvelisa kwiindawo zabo. Eli nqaku liqhekeza ulwahlulo oluphambili phakathi kokuphosa kunye nokwenza ngokwenkqubo, iipropathi zezinto eziphathekayo, iindleko, amandla, kunye nokunye.

Yintoni Ukuphosa?

Iyaphosayinkqubo apho isinyithi inyibilika ibe lulwelo, igalelwe kwingundo, kwaye ivunyelwe ukuba iqine kwimilo ethile. Emva kokupholisa, isikhunta siyasuswa, kwaye imveliso yokugqibela inokugqithwa ngakumbi okanye umatshini.

Kukho iintlobo ezininzi zeenkqubo zokuphosa, kuquka:

• Ukugalelwa kwesanti

• Ukuphosa utyalo-mali (ilahleko-wax)

• Ukuphosa ukufa

• Ukuphosa kwi-Centrifugal

Ukuphosa kukulungele ukuvelisaiijometri ezintsonkothileyokwayeizixa ezikhuluyamacandelo ngeukusebenza kancinci.

Yintoni Ukuqulunqa?

Ukuqulunqayinkqubo yokuvelisa ebandakanyaukubumba isinyithi usebenzisa amandla oxinzelelo, ngokuqhelekileyo ngeehamile okanye oomatshini bokushicilela. Isinyithi siqhelekileishushu kodwa ihlala yomelele, kunye ne-deformation isetyenziselwa ukufezekisa ifom efunwayo.

Iintlobo zokubunjwa ziquka:

• Open-die forging

• Kuvaliwe-kufa forging

• Ukubumba okubandayo

• Ukubumba okufudumeleyo

• Ukuqengqeleka kweringi

Ukuqulunqa kwandisa amandlaamandla oomatshinikwayeimfezeko yolwakhiwoyamacandelo esinyithi ngokulungelelanisa ukuhamba okuziinkozo kwicala loxinzelelo.

Umahluko oPhambili phakathi kokuCasa kunye nokuQinisa

1. Indlela yeNkqubo

• Iyaphosa: Ibandakanyaukunyibilika isinyithikwaye uyigalele kwiimbumba. Izinto eziphathekayo ziqina kwimo efunwayo.

• Ukuqulunqa: Ibandakanyaukuguqula isinyithi esiqinileyousebenzisa amandla omatshini ukufezekisa imilo.

Isishwankathelo: Ukuphosa lulwelo-ukuya-luqilima inguqu, lo gama forging is deformation eqinileyo-state.

2. Iimpahla zeMathiriyeli

• Iyaphosa: Ihlala ibandakanyai-porosity, ukushwabana, kwayeukutya okuziinkozongenxa yenkqubo yokupholisa.

• Ukuqulunqa: Inikezaulwakhiwo olusulungekileyo lweenkozo, ubunzima obukhulu, kwayeukumelana nokudinwa okuphezulu.

Isishwankathelo: Amalungu akhiweyo anamandla kwaye anokwethenjelwa ngakumbi, ngakumbi phantsi kweempembelelo okanye uxinzelelo.

3. Amandla oomatshini

• Iyaphosa: Iphakathi ukuya kumandla aphezulu, kodwa inokuba brittle kwaye ichaphazeleke kukuqhekeka okanye iziphene.

• Ukuqulunqa: Amandla aphezulu ngenxa yokulungelelaniswa kokuhamba kweenkozo kunye nokuxinana kwesinyithi.

Isishwankathelo: Forging ivelisa amacandelo ngeimpembelelo ephezulu kunye namandla okukhathalakunokuphosa.

4. Umphezulu wokuGqibela kunye nokunyamezela

• Iyaphosa: Unokufezekisa umphezulu ogudileyo kunye neemilo ezintsonkothileyo ezinomatshini omncinci.

• Ukuqulunqa: Ngokuqhelekileyo kufuna ukugqitywa kunye nokusebenza ngomatshini, ngakumbi kwiinkqubo ezivulekileyo zokufa.

Isishwankathelo: Ukuphosa kunika ukugqiba kwasekuqaleni okungcono; ukubunjwa kunokufuna imisebenzi yesibini.

5. Ukuntsonkotha koYilo

• Iyaphosa: Ilungeleiimilo ezintsonkothileyokwayeiindonga ezibhityileyooko kuya kuba nzima ukwenza.

• Ukuqulunqa: Ifaneleke ngconoelula ngakumbi, macalaiimilo ngenxa yonyino lwezixhobo.

Isishwankathelo: Ukusatywa kuxhasa izakhiwo ezintsonkothileyo kunye nezingenanto; ukubunjwa kuthintelwe luyilo lokufa.
