Mehato ea bohlokoa ho forging ea crankshaft ea indasteri: Ho tloha ho billet ho isa sehlahisoa se felileng
Ho lokisoa ha billet le ho theha pele
Ts'ebetso ea ho etsa crankshaft e qala ka khetho e hlokolosi le ho lokisoa ha li-billet tsa tšepe. Li-blocks tsena tsa cylindrical kapa rectangular tsa tšepe hangata li khethoa bakeng sa sebopeho sa tsona se ikhethileng sa alloy, se etselitsoeng ho fihlela litlhoko tsa mochini tsa crankshaft ea ho qetela. Mokhahlelo oa pele oa ho theha o kenyelletsa ho futhumatsa billet ho mocheso oa eona o nepahetseng oa ho forging, hangata pakeng tsa 1,100 ° C le 1,250 ° C, ho itšetlehile ka motsoako. Phekolo ena ea mocheso e etsa bonnete ba hore tšepe e bonolo ka ho lekaneng bakeng sa ho bopa ha e ntse e boloka botšepehi ba eona.
Lefu la forging le ho tlosa flash
Hang ha e chesitsoe, billet e fetisetsoa mochine oa khatiso oa forging, moo e kenang letoto la ts'ebetso ea ho hatella le ho etsa sebōpeho ka ho sebelisoa ka mokhoa o khethehileng oa shoa. Lintho tsena tse shoang li fana ka sebōpeho se thata sa crankshaft, ho akarelletsa le limakasine tsa eona tse ka sehloohong, likoranta tsa rod le li-counterweights. Mokhoa oa ho qhekella hangata o kenyelletsa literaeke tse ngata ho fihlela sebopeho se lakatsehang, 'me seteraeke se seng le se seng se hloekisa sebopeho le ho ntlafatsa sebopeho sa lijo-thollo tsa tšepe. Ka mor'a ho qhekella, thepa e feteletseng, e tsejoang e le flash, e khutsufatsoa ho senola sebopeho se haufi-ufi sa crankshaft.
Phekolo ea mocheso le ts'ebetso ea ho qetela
Ka mor'a ts'ebetso ea mantlha ea ho qhekella, the crankshaft e sebetsana le mekhoa e nepahetseng ea phekolo ea mocheso ho ntlafatsa thepa ea eona ea mochine. Sena se ka kenyelletsa ho tloaeleha, ho tima, le ho futhumatsa ho fihlela tekanyo e nepahetseng ea matla le ductility. Mehato ea ho qetela e kenyelletsa ts'ebetso ea machining ho ntlafatsa litekanyo tsa crankshaft, pheletso ea bokaholimo, le likarolo tsa bohlokoa joalo ka litselana tsa oli le libaka tse beretsoeng. Mehato e matla ea taolo ea boleng, ho kenyeletsoa tlhahlobo e sa senyeheng le tlhahlobo ea maemo, e etsa bonnete ba hore crankshaft e 'ngoe le e 'ngoe e ferekaneng e fihlela litlhokahalo tse matla bakeng sa ts'ebeliso ea eona e reriloeng.
Litlhaloso tsa mochini oa forging li ama boleng le ts'ebetso ea crankshaft joang
Tobetsa bokhoni le kabo ea matla
Litlhaloso tsa mochini oa forging li bapala karolo ea bohlokoa ho khethollang boleng le ts'ebetso ea se felileng crankshaft. E 'ngoe ea lintlha tsa bohlokoa ka ho fetisisa ke matla a khatiso, a laelang matla a mangata a ka sebelisoang nakong ea ts'ebetso ea ho qhekella. Mechine e hatisang ea matla a holimo, eo hangata e lekantsoeng ka lithane tse likete, ea hlokahala bakeng sa ho etsa li-crankshaft tse khōlō tse sebelisoang lienjineng tse sebetsang ka thata. Bokhoni ba ho aba matla ana ka mokhoa o ts'oanang ho pholletsa le mosebetsi oa mosebetsi ke oa bohlokoa ka ho lekana, kaha o tiisa hore ho phalla ha thepa e ts'oanang le ho thibela mefokolo e kang mameno kapa likoti mohahong o entsoeng.
Moqapi oa lefu le khetho ea thepa
Moetso oa forging oa shoa 'me thepa e sebelisoang ha ho etsoa li susumetsa haholo boleng ba sehlahisoa sa ho qetela. Moralo o tsoetseng pele oa khomphutha (CAD) le software ea ketsiso li thusa lienjineri ho ntlafatsa li-geometries ho fihlela phallo e nepahetseng ea thepa le ho fokotsa khatello ea maikutlo. Lisebelisoa tsa die li tlameha ho mamella mocheso o feteletseng le likhatello ha li ntse li boloka botsitso ba dimensional. Lisebelisoa tsa lisebelisoa tse phahameng, hangata tse nang le liaparo tse khethehileng, li khethiloe ho etsa bonnete ba hore bophelo ba nako e telele le boleng bo tsitsitseng ba karolo ho pholletsa le nako e telele ea tlhahiso.
Automation le taolo ya tshebetso
Mechini ea sejoale-joale ea crankshaft e kenyelletsang li-automation le litsamaiso tsa taolo ea tšebetso. Litsamaiso tsena li netefatsa taolo e nepahetseng holim'a liparamente tsa bohlokoa joalo ka mocheso oa forging, lebelo la khatiso le nako ea ho lula. Li-sensor tse tsoetseng pele le bokhoni ba ho lekola nako ea nnete li lumella phetoho e tsoelang pele ea li-parameter tsa forging, ho boloka maemo a matle nakong eohle ea ts'ebetso. Boemo bona ba taolo bo bohlokoa bakeng sa ho fihlela boleng bo tsitsitseng ho pholletsa le mefuta e meholo ea tlhahiso le ho eketsa katleho ea ts'ebetso ea ho etsa.
Taolo ea mocheso ho crankshaft forging: Hobaneng e le bohlokoa bakeng sa sebopeho sa lijo-thollo
Ho ntlafatsa phallo ea thepa le ntlafatso ea lijo-thollo
Taolo ea mocheso ke karolo ea bohlokoa ea ts'ebetso ea crankshaft forging, e nang le litlamorao tse tebileng bakeng sa sebopeho sa microstructure le thepa ea mochini ea sehlahisoa se felileng. Taolo e nepahetseng ea mocheso nakong eohle ea potoloho ea forging e thusa ho phalla hantle, ho netefatsa hore tšepe e tlatsa likheo tsohle tsa lefu ka mokhoa o ts'oanang. Phallo ena e ts'oanang e bohlokoa bakeng sa ho fihlela ntlafatso e tsitsitseng ea lijo-thollo ho pholletsa le crankshaft eohle. Mehaho e metle e kenya letsoho ho ntlafatseng matla, ho tiea le ho hanyetsa mokhathala-tsohle litšoaneleho tsa bohlokoa bakeng sa li-crankshaft tse sebetsang hantle tlas'a maemo a feteletseng.
Ho thibela bofokoli le ho netefatsa botsitso ba dimensional
Ho boloka mocheso o nepahetseng nakong ea forging ke habohlokoa bakeng sa ho thibela likoli tse ka senyang botšepehi ba crankshaft. Ho futhumala ho feteletseng ho ka lebisa kholong ea lijo-thollo le oxidation, ha mocheso o tlase o ka fella ka ho tlatsa lefu le sa fellang kapa ho senyeha ha holim'a metsi. Taolo ea mocheso e boetse e phetha karolo ea bohlokoa ho laola katoloso ea mocheso le ho fokotseha, e amang ka ho toba botsitso ba karolo e entsoeng. Lisebelisoa tse tsoetseng pele tsa ho futhumatsa, hammoho le ho beha leihlo mocheso ka nepo, li etsa bonnete ba hore karolo e 'ngoe le e 'ngoe ea crankshaft e entsoe ka mocheso o nepahetseng, ho fokotsa khatello ea maikutlo le ho khopama.
Ho lokisa thepa ea mochini ka ho pholisa ho laoloang
Sekhahla sa ho pholisa ka mor'a ho qhekella se bohlokoa ka ho lekana ho khethollang thepa ea ho qetela ea crankshaft. Mekhoa ea ho pholisa e laoloang, joalo ka ho pholisa moea kapa ho tima, e ka sebelisoa ho fihlela sebopeho se itseng sa microstructures le thepa ea mochini. Ka mohlala, ho pholisa ka potlako ho ka 'na ha sebelisoa ho susumetsa sebopeho sa martensite bakeng sa ho thatafala ho eketsehileng, ha litekanyetso tsa ho phomola butle li ka khothalletsa ho thehoa ha mekhahlelo e mengata ea ductile. Ka ho laola ts'ebetso ea ho pholisa ka hloko, bahlahisi ba ka hlophisa thepa ea crankshaft ho fihlela litlhoko tse ikhethileng tsa meralo e fapaneng ea enjine le maemo a ts'ebetso.
Qetellong, ke crankshaft meralo ea mochini oa forging le moralo oa mochini ke lintlha tsa bohlokoa tlhahisong ea likarolo tsa enjene tse sebetsang hantle haholo. Ka ho sebelisa mahlale a tsoetseng pele le taolo e nepahetseng holim'a karolo e 'ngoe le e' ngoe ea ts'ebetso ea ho qhekella, bahlahisi ba ka hlahisa li-crankshaft tse fihlelang litlhoko tse batloang ke lienjine tsa sejoale-joale. Bakeng sa tlhaiso-leseling e batsi ka crankshaft forging le lihlahisoa tse ling tsa oli, ka kopo ikopanye le rona ho oiltools15@welongpost.com. Welong e ikemiselitse ho fana ka likarolo tsa boleng bo holimo le tataiso ea litsebi lefapheng la tlhahiso ea indasteri le taolo ea ketane ea phepelo.
