Blacksmithing ke mokhoa oa khale le oa bohlokoa oa ho sebetsa ka tšepe o qalileng ka 2000 BC.E sebetsa ka ho futhumatsa tšepe e se nang letho mochesong o itseng ebe e sebelisa khatello ho e bōpa hore e be sebopeho se lakatsehang.Ke mokhoa o tloaelehileng oa ho etsa likarolo tse matla, tse tšoarellang haholo.Ts'ebetsong ea ho qhekella, ho na le mekhoa e 'meli e tloaelehileng, e leng ho forging mahala le die forging.Sengoliloeng sena se tla hlahloba liphapang, melemo le mathata, le ts'ebeliso ea mekhoa ena e 'meli.
Free Forging
Ho forging mahala, ho tsejoang hape e le forging hamore ea mahala kapa mokhoa oa mahala oa forging, ke mokhoa oa ho etsa tšepe ntle le hlobo.Ts'ebetsong ea mahala ea ho qhekella, sekheo sa forging (hangata sekontiri sa tšepe kapa molamu) se futhumatsoa ho mocheso moo se fetohang polasetiki e lekaneng ebe se bōptjoa ka sebopeho se lakatsehang ho sebelisoa thepa e kang hamore ea forging kapa mochine oa khatiso oa forging.Ts'ebetso ena e itšetlehile ka litsebo tsa basebetsi ba sebetsang, ba hlokang ho laola sebōpeho le boholo ka ho shebella le ho tseba mokhoa oa ho etsa.
Melemo ea ho forging mahala:
1. Ho feto-fetoha ha maemo: Free forging e loketse li-workpieces tsa libopeho le boholo bo fapaneng hobane ha ho hlokahale ho etsa hlobo e rarahaneng.
2. Ho boloka thepa: Kaha ha ho na hlobo, ha ho hlokahale lisebelisoa tse eketsehileng ho etsa hlobo, e ka fokotsang litšila.
3. E loketse tlhahiso ea lihlopha tse nyenyane: Ho qhekella mahala ho loketse bakeng sa tlhahiso ea lihlopha tse nyenyane hobane tlhahiso ea bongata ba hlobo ha e hlokehe.
Mathata a ho forging mahala:
1. Ho itšetleha ka litsebo tsa basebetsi: Boleng ba ho forging mahala bo itšetlehile ka litsebo le phihlelo ea basebetsi, kahoo litlhoko tsa basebetsi li phahame.
2. Lebelo le liehang la tlhahiso: Ha le bapisoa le lefu la forging, lebelo la tlhahiso ea ho forging mahala le lieha.
3. Taolo ea sebopeho le boholo e thata: Ntle le thuso ea hlobo, taolo ea sebopeho le boholo ka ho forging mahala e thata ebile e hloka ts'ebetso e latelang.
Lisebelisoa tsa mahala tsa forging:
Ho qhekella mahala ho tloaelehile libakeng tse latelang:
1. Ho hlahisa mefuta e fapaneng ea likarolo tsa tšepe tse kang forging, likarolo tsa hamore, le li-castings.
2. Hlahisa likarolo tsa mochini tse matla haholo le tse tšoarellang haholo joalo ka li-crankshafts, lithupa tse hokelang le li-bearings.
3. Ho lahlela likarolo tsa bohlokoa tsa mechini e boima le lisebelisoa tsa boenjiniere.
Shoa Forging
Die forging ke mokhoa o sebelisang dies ho forge tšepe.Ts'ebetsong ena, tšepe e se nang letho e kenngoa ka har'a hlobo e entsoeng ka mokhoa o khethehileng ebe e bōptjoa hore e be sebopeho se lakatsehang ka khatello.Hlobo e ka ba e le 'ngoe kapa likarolo tse ngata, ho itšetlehile ka ho rarahana ha karolo.
Melemo ea ho etsa die forging:
1. Ho nepahala ho phahameng: Die forging e ka fana ka sebopeho se nepahetseng haholo le taolo ea boholo, ho fokotsa tlhokahalo ea ts'ebetso e latelang.
2. Phallo e phahameng: Kaha hlobo e ka sebelisoa ka makhetlo a mangata, ho hlahisa hlobo ho loketse bakeng sa tlhahiso ea bongata le ho ntlafatsa katleho ea tlhahiso.
3. Ho tsitsisa hantle: Die forging e ka netefatsa ho lumellana ha karolo ka 'ngoe le ho fokotsa ho fetoha.
Mathata a ho etsa die forging:
1. Litšenyehelo tse phahameng tsa tlhahiso: Litsenyehelo tsa ho etsa liforomo tse rarahaneng li batla li le holimo, haholo-holo bakeng sa tlhahiso ea lihlopha tse nyenyane, tse sa lefelloeng.
2. Ha e tšoanelehe bakeng sa libopeho tse khethehileng: Bakeng sa likarolo tse rarahaneng haholo kapa tse sa tloaelehang, liforomo tsa tloaelo tse theko e boima li ka 'na tsa hloka ho etsoa.
3. Ha e tšoanelehe bakeng sa forging e tlaase ea mocheso: Die forging hangata e hloka mocheso o phahameng 'me ha e tšoanelehe bakeng sa likarolo tse hlokang ho forging mocheso o tlaase.
Lisebelisoa tsa ho etsa thepa ea maiketsetso:
Die forging e sebelisoa haholo mafapheng a latelang:
1. Ho hlahisa likarolo tsa likoloi tse kang li-crankshafts tsa enjene, li-brake discs, le li-hubs tsa mabili.
2. Ho etsa likarolo tsa bohlokoa bakeng sa lefapha la sefofane, tse kang li-fuselage tsa lifofane, likarolo tsa enjene le likarolo tsa taolo ea sefofane.
3. Hlahisa likarolo tsa boenjiniere tse nepahetseng haholo tse kang li-bearings, likere le li-racks.
Ka kakaretso, forging mahala le die forging e 'ngoe le e' ngoe e na le melemo le mefokolo ea eona 'me e loketse litlhoko tse fapaneng tsa tlhahiso.Ho khetha mokhoa o loketseng oa ho qhekella ho itšetlehile ka ho rarahana ha karolo, bophahamo ba tlhahiso, le ho nepahala ho hlokahalang.Lits'ebetsong tse sebetsang, lintlha tsena hangata li hloka ho lekanngoa ho fumana mokhoa o nepahetseng oa ho qhekella.Ntlafatso e tsoelang pele le ntlafatso ea lits'ebetso tsa ho qhekella e tla tsoelapele ho tsamaisa libaka tsa ts'ebeliso ea mekhoa ka bobeli.
Zhengxi ke setsebifeme ea khatiso ea forging naheng ea China, e fanang ka boleng bo phahameng mahalaho qhekella mechesole ho shoa ho qhekella likhatiso.Ho phaella moo, mechine ea khatiso ea hydraulic e ka boela ea etsoa le ho hlahisoa ho latela litlhoko tsa bareki.Haeba u na le litlhoko, ka kopo ikopanye le rona.
