Tlhahlobo ea Melemo le Mathata a Open Die Forging le Closed Die Forging

Open die forging le "closed die forging" ke mekhoa e 'meli e tloaelehileng ea lits'ebetso tsa ho qhekella, e' ngoe le e 'ngoe e na le liphapang tse fapaneng mabapi le ts'ebetso ea ts'ebetso, boholo ba ts'ebeliso, le katleho ea tlhahiso. Sengoliloeng sena se tla bapisa litšobotsi tsa mekhoa ka bobeli, ho sekaseka melemo le likotsi tsa bona ho fana ka motheo oa ho khetha mokhoa o nepahetseng oa ho theha.

1. Bula Die Forging

Open die forging e bua ka mokhoa oo ho oona ho sebelisoang matla ka ho toba ho workpiece ho sebelisa lisebelisoa tse bonolo, tse sebelisoang ka kakaretso kapa pakeng tsa li-anvils tse ka holimo le tse ka tlaase tsa thepa ea forging ho holofatsa thepa le ho finyella sebopeho se lakatsehang le boleng ba ka hare ba sengoathoana se entsoeng. Mokhoa ona o sebelisoa hangata bakeng sa tlhahiso ea li-batch tse nyane, 'me hangata lisebelisoa li kenyelletsa lihamore tsa forging le likhatiso tsa hydraulic. Mekhoa ea mantlha ea ho qhekella ha lefu le bulehileng e kenyelletsa ho ferekanya, ho hula, ho otla ka litebele, ho itšeha le ho kobeha, 'me hangata ho kenyelletsa mekhoa e chesang ea ho qhekella.

Melemo:

1. Ho tenyetseha ho phahameng: E loketse ho hlahisa li-forging tsa libopeho tse sa tšoaneng le mefuta ea boima ba 'mele, ho tloha likarolong tse nyenyane tse boima ba lik'hilograma tse 100 ho ea likarolong tse boima tse fetang lithane tse 300.
2. Litlhoko tsa thepa e tlaase: Lisebelisoa tse bonolo, tse akaretsang li sebelisoa, 'me litlhoko tsa tonnage tsa thepa li batla li le tlaase. E na le potoloho e khuts'oane ea tlhahiso, e etsang hore e tšoanelehe bakeng sa tlhahiso e potlakileng kapa e nyane.

Mefokolo:

1. Ts'ebetso e tlase: Ha ho bapisoa le ho koaleha ha shoa, katleho ea tlhahiso e tlaase haholo, e etsa hore ho be thata ho finyella litlhoko tsa tlhahiso e kholo.
2. Sebopeho se lekanyelitsoeng le ho nepahala: Likarolo tse entsoeng ka maiketsetso hangata li bonolo ka sebopeho, li na le ho nepahala ha maemo a tlase le boleng bo bobe ba bokaholimo.
3. Matla a phahameng a mosebetsi: Basebetsi ba nang le litsebo baa hlokahala, 'me ho thata ho fumana mochine le ho iketsetsa mochine.

2. Ho Koetsoe Die Forging

Ho koaleha lefu la forging ke mokhoa oo workpiece e bōpehileng ka eona ka lisebelisoa tse khethehileng tsa ho forging, e leng se etsang hore e tšoanelehe bakeng sa tlhahiso ea boima. Lisebelisoa tse sebelisoang li kenyelletsa lihamore tsa ho etsa lihamore, mechine ea khatiso ea crank, le mechine e meng e khethehileng. Mokhoa oa ho qhekella o kenyelletsa pele ho forging le finish forging, 'me li-dies li entsoe ka hloko ho hlahisa libopeho tse rarahaneng tse nang le bokhoni bo phahameng.

Melemo:

1. Bokgoni bo phahameng: Kaha deformation ea tšepe e etsahala ka har'a sekoti sa die, sebopeho se lakatsehang se ka fumanoa ka potlako, se lebisang ho lebelo la tlhahiso ea lihlahisoa.
2. Libopeho tse rarahaneng: Thepa e koetsoeng ea lefu e ka hlahisa li-forging tse nang le sebōpeho se rarahaneng tse nang le ho nepahala ho phahameng le mekhoa e utloahalang ea ho phalla ha tšepe, ho ntlafatsa bophelo ba tšebeletso ea likarolo.
3. Ho boloka lintho tse bonahalang: Forgings tse hlahisoang ke mokhoa ona li na le tumello e fokolang ea machining, boleng bo holimo bo holimo, le ho fokotsa palo ea mosebetsi o latelang oa ho itšeha, o lebisang polokelong ea thepa.

Mefokolo:

1. Litšenyehelo tse phahameng tsa thepa: Potoloho ea ho etsa lintho tsa forging e telele, 'me litšenyehelo li holimo. Ho feta moo, matsete a thepa e koetsoeng ea ho etsa thepa e kholo ho feta ea forging e bulehileng.
2. Meeli ea boima: Ka lebaka la mefokolo ea lisebelisoa tse ngata tsa ho qhekella, liforomo tse koetsoeng hangata li lekantsoe boima bo ka tlase ho 70 kg.

3. Qetello

Ka bokhuts'oane, open die forging e loketse bakeng sa li-batch tse nyane, maemo a tlhahiso a tenyetsehang 'me a loketse ho etsa liforomo tse kholo kapa tse bonolo. Ka lehlakoreng le leng, ho koaleha die forging ho loketse haholoanyane bakeng sa tlhahiso e kholo ea li-forging tse nang le sebōpeho se rarahaneng. E fana ka katleho e phahameng le ho boloka lintho tse bonahalang. Ho khetha mokhoa o nepahetseng oa ho qhekella ho ipapisitse le sebopeho, litlhoko tse nepahetseng, le tekanyo ea tlhahiso ea lifeme ho ka ntlafatsa haholo katleho ea tlhahiso le ho fokotsa litšenyehelo.
