Flange ea Cast le flange e entsoeng ke li-flange tse tloaelehileng, empa mefuta e 'meli ea li-flange e fapane ka theko.
Flange ea cast e na le sebōpeho le boholo bo nepahetseng, molumo o monyenyane oa ho sebetsa le theko e tlaase, empa e na le liphoso tsa ho lahla (tse kang li-pores, cracks le inclusions);Sebopeho sa ka hare sa ho lahla ha se sebetse hantle;Molemo ke hore o ka etsa sebopeho se rarahaneng haholoanyane, 'me litšenyehelo li batla li le tlaase;
E qhetsoengflangeska kakaretso li na le khabone e tlase ho feta li-flanges 'me ha ho bonolo ho rusa.Forgings e na le streamline e ntle, sebopeho sa compact le thepa e ntle ea mochini ho feta li-flanges tse entsoeng;Mokhoa o sa nepahalang oa ho qhekella o tla boela o lebise ho lijo-thollo tse kholo kapa tse sa tsitsang le mapetsong a thata, 'me litšenyehelo tsa ho qhekella li phahame ho feta tsa flange e entsoeng.Forgings e ka mamella matla a phahameng a ho kuta le a thata ho feta li-castings.Melemo ke hore mohaho oa ka hare o ts'oana 'me ha ho na liphoso tse kotsi tse kang li-pores le li-inclusions ho lahla;
Phapang pakeng tsa flange ea cast le flange e entsoeng e itšetlehile ka mokhoa oa tlhahiso.Ka mohlala, centrifugal flange ke mofuta oa flange e entsoeng.Centrifugal flange ke ea mokhoa o nepahetseng oa ho lahla ho hlahisa flange.Ha ho bapisoa le ho lahla lehlabathe le tloaelehileng, mofuta ona oa ho lahla o na le sebopeho se setle haholo le boleng bo betere, 'me ha ho bonolo ho ba le mathata a kang sebopeho se hlephileng, lesoba la moea le trachoma.
Ha re utloisise ts'ebetso ea tlhahiso ea flange e qhekelitsoeng hape: mokhoa oa ho qhekella hangata o na le lits'ebetso tse latelang, e leng, ho khetha ho koaheloa ha boleng bo holimo ba billet, ho futhumatsa, ho theha le ho pholisa ka mor'a ho forging.
The forging process akarelletsa free forging, die forging le die film forging.Nakong ea tlhahiso, mekhoa e fapaneng ea ho qhekella e tla khethoa ho latela boholo ba boleng ba forging le batch ea tlhahiso.Ho qhekella mahala ho na le tlhahiso e tlase le tumello e kholo ea machining, empa sesebelisoa se bonolo ebile se na le mefuta e mengata, ka hona se sebelisoa haholo bakeng sa ho theha sekotoana se le seng le li-batch tse nyane tse nang le sebopeho se bonolo.Lisebelisoa tsa mahala tsa forging li kenyelletsa hamore ea moea, hamore ea mouoane le mochini oa khatiso oa hydraulic, tse loketseng ka ho latellana bakeng sa tlhahiso ea liforomo tse nyane, tse mahareng le tse kholo.Die forging e na le tlhahiso e phahameng, ts'ebetso e bonolo, 'me ho bonolo ho elelloa ts'ebetso le boiketsetso.Die forgings li na le ho nepahala ha maemo a holimo, tumello e nyane ea machining, le kabo e nepahetseng ea sebopeho sa fiber ea forging, e ka ntlafatsang bophelo ba litšebeletso tsa likarolo.
1, Ts'ebetso ea mantlha ea ho forging mahala: nakong ea forging ea mahala, sebopeho sa forging se thehoa butle-butle ke lits'ebetso tse ling tsa mantlha tsa deformation.Mekhoa ea motheo ea ho qhekella mahala e kenyelletsa ho ferekanya, ho taka, ho otla, ho kobeha le ho itšeha.
1. Ho ferekanya ke ts'ebetso ea ts'ebetso ea ho theha sekheo sa pele ho latela tataiso ea axial ho fokotsa bophahamo ba eona le ho eketsa karolo ea eona ea sefapano.Ts'ebetso ena hangata e sebelisoa bakeng sa ho etsa likheo tsa li-gear le li-forging tse ling tse nang le sebopeho sa disc.Ho halefisa ho arotsoe ka ho khopisa ka ho feletseng le ho ferekanya ka mokhoa o itseng.
2. Ho taka ke mokhoa oa ho forging o eketsang bolelele ba sekoti le ho fokotsa karolo ea sefapano.Hangata e sebelisoa ho hlahisa likarolo tsa shaft, tse kang lathe spindle, rod e kopanyang, joalo-joalo.
3. Punching/ Mokgoa wa ho phunya kapa ho phunya masoba le masobeng a phahlo.
4. Mokhoa oa ho phunya oa ho kobeha sekheo ka lehlakoreng le itseng kapa sebopeho.
5. Mokhoa oa ho theha moo karolo e 'ngoe ea sekheo e potolohang ka lehlakoreng le itseng le amanang le le leng.
6. Ho theha mokhoa oa ho khaola le ho arola hlooho ea thepa e se nang letho kapa e sehang.
2、 Shoa foring;Lebitso le felletseng la ho forging ke mohlala oa forging, o thehiloeng ka ho beha sekheo se futhumetseng ka har'a sesebelisoa sa forging se behiloeng holim'a thepa ea forging.
1. Ts'ebetso ea mantlha ea ho etsa "die forging": ho koala, ho futhumatsa, ho qhekella, ho phunya ka litebele, ho poma, ho futhumatsa, ho penta.Mekhoa e tloaelehileng e kenyelletsa ho ferekanya, ho taka, ho koba, ho otla le ho theha.
2. Thepa e tloaelehileng ea thepa ea ho etsa thepa e tloaelehileng ea ho etsa thepa e kenyelletsa hamore ea ho etsa die, mochini o chesang oa ho etsa mochine o chesang, mochine oa ho fereka o bataletseng, mochine oa ho ferekanngoa, joalo-joalo.
3, ho khaola flange;Seha ka ho toba bophara ba ka hare le ka ntle le botenya ba flange ka tumello ea machining holim'a poleiti e bohareng, ebe o sebetsana le lesoba la bolt le mohala oa metsi.Ka hona, flange e hlahisoang e bitsoa "cutting flange".Boholo ba bophara ba flange e joalo bo lekanyelitsoe ho bophara ba poleiti e bohareng.
4. Letlapa le phuthetsoeng;Mokhoa oa ho sebelisa poleiti e mahareng ho seha likhoele ebe o li phutholla ka selikalikoe o bitsoa coiling, e sebelisoang haholo ho hlahisa li-flange tse ling tse kholo.Ka mor'a hore ho phethoe ka katleho, ho tla etsoa welding, ebe ho etsoa flattening, ebe ho sebetsanoa ha metsi le lesoba la bolt ho tla etsoa.
