Ka lebaka la kamano e haufi pakeng tsa moralo oa hlobo le ts'ebetso ea tlhahiso le phepelo ea thepa ea hlobo e holimo, kalafo ea mocheso, phepelo ea forging, likarolo tse tloaelehileng tsa hlobo, le likarolo / lihlahisoa tsa mochini o tlase (likarolo tsa polasetiki, likarolo tsa ho lahla, joalo-joalo), tse ngata. likhoebo tsa hlobo li na le hlobo le lihlahisoa.Ka hona, ketane ea indasteri ea hlobo e arotsoe likarolo tse tharo: "likhoebo tse tšehetsang holimo", "meralo ea hlobo le likhoebo tsa tlhahiso", le "likhoebo tse atolositsoeng tse tlase".
1.2.1 Likhoebo tse tšehetsang ka holimo
Ho na le phepelo ea thepa ea hlobo e fetang 150, kalafo ea mocheso, phepelo ea forging, le likhoebo tse ling tse tšehetsang tse amanang le moralo le tlhahiso ea hlobo, tse nang le basebetsi ba fetang 5000.
1.2.2 Likhoebo tsa meralo le tlhahiso ea hlobo
Ho na le likhoebo tse 1372 tsa hlobo Beilun, tse sebetsanang ka kotloloho le likarolo tsa hlobo le likarolo tsa hlobo, tse nang le basebetsi ba fetang 16000.
(1) Lipalopalo tsa likhoebo tsa hlobo tse ipapisitseng le kabo ea libaka
Hoo e ka bang 70% ea kabo ea tikoloho ea likhoebo tsa hlobo Beilun e tsepamisitsoe Daqi, e lateloe ke Xiapu accounting bakeng sa 11.37%.Khatiso ea libaka "ke tšobotsi ea likhoebo tsa Beilun hlobo.
(2) Sehlopha se ipapisitse le mofuta oa ngoliso ea likhoebo
Ho ea ka lipalo-palo tsa Beilun Mold Enterprises ka mofuta oa khoebo, har'a likhoebo tsa hlobo tse 372, likhoebo tsa malapeng li etsa 96%.Likhoebo tse ikemetseng li bapala karolo ea pele "ke tšobotsi e 'ngoe ea likhoebo tsa Beilun mold.
(3) Ho arola ka mofuta oa hlobo
Mefuta ea mantlha ea hlobo Beilun ke liforomo tse lahlehang le liforomo tsa polasetiki, 'me likhoebo tse ling li na le tsona ka bobeli.Li-molds tse etsang li-die-casting li etsa 75% ho isa ho 80%, hlobo ea polasetiki e nka 15% ho isa ho 20%, 'me mefuta e meng e etsa 5% ho isa ho 8%.
1.2.3 Likhoebo tsa katoloso tse tlase
E ipapisitse le mofuta oa hlobo, likhoebo tse atolositsoeng ka tlase li shebana haholo le li-die castings, likarolo tsa polasetiki, likarolo tsa rabara le likarolo tsa setempe.Ka mohlala, Beilun Daqi, moo tlhahiso ea die-casting e tsepamisitsoeng, indasteri ea tlhahiso ea lihlahisoa e tsoetse pele ho tloha indastering ea tlhahiso ea hlobo.Daqi e na le likhoebo tse fetang 60 tse hlahisang lihlahisoa, ho feta metjhini e fetang 400 ea mefuta e fapaneng, e nang le litlhaloso ho tloha ho 1250 kN ho isa 25000 kN.Ho na le lik'hamphani tse fetang 150 tsa katoloso ea noka Beilun.
1.3 Karolo ea boleng ba tlhahiso ea hlobo ea Beilun naheng
Ho ea ka litekanyetso tsa naha, hlobo e arotsoe ka mekhahlelo e leshome, 'me li-stamping hlobo le hlobo ea polasetiki ke tsona lihlahisoa tse ka sehloohong Chaena.Ka nts'etsopele ea indasteri ea likoloi le lithuthuthu lilemong tsa morao tjena, karolo ea hlobo ea polasetiki le hlobo e ntseng e eketseha e ntse e eketseha selemo le selemo.Ho ea ka lipalo-palo tsa Mokhatlo oa Chaena oa Mould, ka 2001, hlobo ea litempe e ne e le karolo ea 50% ea sebopeho sa lihlahisoa tsa China, hlobo ea polasetiki e ka bang 34%, hlobo e bolaeang e ka bang 6%, 'me mefuta e meng ea hlobo e tlalehoa. hoo e ka bang 10%;Ka nts'etsopele e potlakileng ea liindasteri tsa lithuthuthu, tsa likoloi le tsa lisebelisoa tsa lapeng, indasteri ea ho etsa li-die-cast e tsoetse pele ka potlako, 'me boleng ba tlhahiso ea liforomo tse bolaeang bo eketsehile.Ho ea ka lipalo-palo tsa 2003, hlobo e bolaeang ke ea bobeli feela ho li-punch hlobo le hlobo ea polasetiki ho latela tlhahiso le bongata, e leng karolo ea 8% ea tlhahiso eohle ea mefuta e sa tšoaneng ea hlobo;Ha indasteri ea likoloi e fetoha e 'ngoe ea liindasteri tsa litšiea Chaena le mokhoa oa nts'etsopele ea lihlahisoa tse bobebe, tse tala, le tse bolokang matla, tlhahiso ea likarolo tsa tšepe tse se nang ferrous le hlobo e eketsehile haholo.Ho ea ka lipalo-palo tsa lisampole tsa lifeme tsa naha tse bolaeang ka 2006, boleng ba tlhahiso ea hlobo e bolaeang naheng ea China e bakile karolo ea 10% ea kakaretso ea boleng ba indasteri ea hlobo.
Kotara e le 'ngoe ea kakaretso ea boleng ba lihlahisoa tsa liforomo tsa naha e tsoa ho likhoebo tsa Beilun die-casting hlobo, tse totobatsang boemo ba bohlokoa ba indasteri ea hlobo ea Beilun naheng.
2. Boemo ba hona joale ba theknoloji ea hlobo ea Beilun die-casting
Hajoale, likhoebo tsa mokokotlo oa mokokotlo oa Beilun li sebelisitse theknoloji ea CAD/CAM moralong le ts'ebetsong ea tlhahiso, 'me tse ling tsa tsona li tlatselletsoa ke CAE bakeng sa ho etsa tlhahlobo ea papiso.Nakong ea ts'ebetso, tšepe ea boleng bo phahameng e sa keneleng mocheso H13 e fetohile khetho e ka sehloohong ea tšepe.Vacuum quenching, machining e nepahetseng ka mor'a ho tima, ho kopanya le ho lokisa mochine o koalang hlobo, le ho hlahloba lisebelisoa tse tharo tse hokahaneng tsa ho lekanya li fetohile mekhoa le mekhoa e tloaelehileng ea bohlokoa.Mabapi le basebetsi ba botekgeniki ba likhoebo, ho na le lienjiniere tse phahameng tse fetang 500, 'me lik'hamphani tse ling li boetse li hlahisitse litsebi tsa kantle ho naha tse tsoang Jeremane, Japane le Korea Boroa ho tataisa moralo le tlhahiso ea hlobo.Ka nako e ts'oanang, liindasteri tse tšehetsang joalo ka kalafo ea mocheso le ts'ebetso ea forging Beilun le tsona li fihletse tsoelo-pele e itseng.
2.1 Theknoloji ea Moralo
Mold CAD/CAE/CAM ke thekenoloji ea bohlokoa bakeng sa ho fetola moralo oa mofuta oa setso le mekhoa ea tlhahiso, e nolofalletsang litsebi tsa boenjiniere ho sebelisa likhomphutha ho rala le ho ntlafatsa ts'ebetso ea sehlahisoa, sebopeho sa hlobo, mokhoa oa ho etsa, le machining a CNC.Sena se ka khutsufatsa haholo moralo oa hlobo le potoloho ea tlhahiso, sa fokotsa litšenyehelo tsa tlhahiso, le ho ntlafatsa boleng ba sehlahisoa.
Likhoebo tse ngata tsa Beilun li sebelisitse theknoloji ea CAD/CAM haholo ts'ebetsong ea ho etsa hlobo, 'me butle-butle li fetohile ho tloha ho moralo oa mahlakore a mabeli ho ea ho moralo oa likarolo tse tharo.Theknoloji e kopaneng ea tlhahiso e kopanyang moralo oa likarolo tse tharo le lisebelisoa tsa mochini oa CNC e khothalelitsoe butle, mme ts'ebetso ea digitization ea tlhahiso ea hlobo e batla e phahame.Likhoebo tsa tlhahiso ea hlobo tse kaholimo ho boholo bo behiloeng li thehile mafapha a meralo a 2D le 3D mme a rekoa.
Lintlha tse ka holimo li tsoa laebraring ea koranta.Bakeng sa liforomo tse ling tse bolaeang, ka kopo ela hloko Fenda Mold.
