5) Ho nepahala ha dimensional le litlhoko tsa mamello ea geometri tsa karolo li thata haholo. Ka kakaretso, mamello ea liprofaele tse nepahetseng tsa aluminium alloy e matla ho feta habeli ho feta mamello e khethehileng ea maemo a JIS, GB le ASTM. Mamello ea botenya ba lebota ea li-profiles tsa alloy tsa aluminium tse nepahetseng ka kakaretso e tlameha ho ba pakeng tsa ± 0.04mm le 0.07mm, athe mamello ea boholo ba karolo ea liprofaele tsa alloy ea aluminium e ka bang ± 0.01mm. Ka mohlala, boima ba profil ea aluminium e nepahetseng e sebelisetsoang potentiometer ke 30g / m, 'me tekanyo ea mamello ea boholo ba karolo ke ± 0.07mm. Mamello ea boholo ba likarolo tse fapaneng tsa profiles tse nepahetseng tsa aluminium bakeng sa looms ke ± 0.04mm, ho kheloha ha angle ho ka tlase ho 0.5 °, 'me tekanyo ea ho kobeha ke 0.83×L. Mohlala o mong ke phaephe e pharalletseng e tšesaane e phahameng haholo bakeng sa likoloi, e bophara ba 20mm, bolelele ba 1.7mm, botenya ba lerako ba 0.17±0.01mm, le masoba a 24, e leng lintlha tse tloaelehileng tsa aluminium alloy profiles.
(6) E na le litaba tse phahameng tsa theknoloji 'me e thata haholo ho e hlahisa,' me e na le litlhoko tse khethehileng tsa lisebelisoa tsa extrusion, lisebelisoa, li-billet le mekhoa ea tlhahiso. Setšoantšo sa 1 ke mohlala oa karolo ea li-profiles tse nyane tse nepahetseng tsa aluminium alloy.
2. Sehlopha sa aluminium motsoako o khethehileng lisebelisoa tsa extrusion tse nepahetseng
Precision kapa ultra-precision aluminium alloy extrusions ho pharaletseng sebelisoa ka liletsa tsa elektronike, thepa ea puisano le saense ea ho itšeha, tšireletso ea naha le indasteri ea sesole, liletsa ho nepahala mechine, thepa e fokolang hona joale, sefofane, indasteri ea nyutlelie, matla le matla, likepe tse tsamaeang ka tlas'a metsi le likepe, likoloi le lisebelisoa tsa lipalangoang , lisebelisoa tsa bongaka, lisebelisoa tsa hardware, mabone, ho nka lifoto le lisebelisoa tsa elektroniki. Ka kakaretso, li-extrusions tsa alloy tsa aluminium tse nepahetseng kapa tse nepahetseng ka ho fetesisa li ka aroloa ka mekhahlelo e 'meli ho latela litšobotsi tsa bona tsa ponahalo: sehlopha sa pele ke lintlha tse nang le litekanyo tse nyane. Mofuta ona oa profil o boetse o bitsoa "ultra-small profile" kapa "mini-shape". Boholo ba eona ka kakaretso hangata ke limilimithara tse seng kae feela, bonyane botenya ba lebota bo ka tlase ho 0.5mm, 'me boima ba yuniti ke ligrama tse' maloa ho isa ho mashome a ligrama ka mithara. Ka lebaka la boholo ba bona bo fokolang, hangata ho hlokahala mamello e thata ho bona. Ka mohlala, mamello ea litekanyo tsa li-cross-sectional e ka tlase ho ± 0.05mm. Ho phaella moo, litlhoko tsa ho otloloha le torsion ea lihlahisoa tse extruded le tsona li thata haholo.
Mofuta o mong ke oa li-profiles tse seng nyane haholo ka boholo ba likarolo tse fapaneng empa li hloka mamello e thata haholo ea li-dimensional, kapa li-profile tse nang le sebopeho se rarahaneng sa likarolo le botenya ba lerako le lesesaane le hoja boholo ba likarolo li le kholo. Setšoantšo sa 2 se bonts'a tube e nang le sebōpeho se khethehileng (aluminium e hloekileng ea indasteri) e fetisitsoeng ke k'hamphani ea Majapane ka mochine oa khatiso oa hydraulic o nang le 16.3MN o nang le mochine o khethehileng oa ho arohana bakeng sa condenser ea moea oa koloi. Bothata ba ho etsa extrusion ea mofuta ona oa profil ha bo tlase ho feta ba mofuta oa pele oa profil e nyane haholo. Li-profile tse atolositsoeng tse nang le boholo ba karolo e kholo le litlhoko tse thata tsa mamello ha li hloke feela theknoloji e tsoetseng pele ea moralo oa hlobo, empa hape li hloka theknoloji e thata ea taolo bakeng sa ts'ebetso eohle ea tlhahiso ho tloha ho sekheo ho isa sehlahisoa se felileng.
Ho tloha mathoasong a lilemo tsa bo-1980, ka lebaka la ts'ebeliso e sebetsang ea Conform continuous extrusion technology le nts'etsopele ea thekenoloji ea indasteri, extrusion ea litlaleho tse nyenyane le tse nyenyane haholo li tsoetse pele ka potlako. Leha ho le joalo, ka lebaka la mabaka a fapaneng a kang mefokolo ea thepa, litlhoko tsa boleng ba sehlahisoa, le tsoelo-pele ea theknoloji ea extrusion, tlhahiso ea litlaleho tse nyenyane ka thepa e tloaelehileng ea extrusion e ntse e ikarabella ka karolo e kholo. Setšoantšo sa 2 se bontša lintlha tse nepahetseng tsa extrusion ea ho arohana ho tloaelehileng ho shoa. Bophelo ba hlobo (haholo-holo matla le ho apara ho hanyetsa ha borokho ba shunt le mokokotlo oa hlobo) le phallo ea thepa nakong ea extrusion e fetoha lintlha tse ka sehloohong tse amang tlhahiso ea eona. Sena ke hobane ha extruding profil, boholo ba hlobo konokono e nyenyane 'me sebopeho e rarahane,' me matla le ho apara ho hanyetsa ke lintlha tsa bohlokoa tse amang bophelo ba hlobo, bophelo ba hlobo bo ama ka ho toba litšenyehelo tsa tlhahiso. Ka lehlakoreng le leng, litlaleho tse ngata tse nepahetseng li na le marako a tšesaane le libopeho tse rarahaneng, 'me ho phalla ha thepa nakong ea ts'ebetso ea extrusion ho ama ka ho toba sebopeho le ho nepahala ha likarolo.
E le ho thibela filimi ea oxide le oli holim'a billet hore e se ke ea phalla ka har'a sehlahisoa le ho netefatsa boleng bo ts'oanang le bo ka tšeptjoang ba sehlahisoa, billet e futhumetseng ho ea mocheso o behiloeng e ka ebola pele ho extrusion (e bitsoang peeling e chesang), le ebe o kenya ka potlako moqomong oa extrusion bakeng sa extrusion. Ka nako e ts'oanang, gasket ea extruded e lokela ho bolokoa e hloekile ho thibela oli le litšila ho khomarela gasket nakong ea ts'ebetso ea ho tlosa khatello e feteletseng ka mor'a extrusion e le 'ngoe le ho kenya gasket ka extrusion e latelang.
Ho ea ka ho nepahala ha karolo ea likarolo le sebopeho le mamello ea boemo, extrusion e khethehileng ea aluminium alloy extrusion e ka aroloa ka li-profiles tsa alloy tse khethehileng tse nepahetseng le tse nyenyane (tse nyenyane) tse phahameng ka ho fetisisa tse phahameng tsa aluminium alloy profiles. Ka kakaretso, ho nepahala ha eona ho feta maemo a naha (joalo ka GB, JIS, ASTM, joalo-joalo) ho nepahala ha ultra-high ho bitsoa li-profiles tse khethehileng tsa aluminium alloy, mohlala, mamello ea dimensional e ka holimo ho ± 0.1mm, mamello ea botenya ba lerako. sebaka se robehileng se ka hare ho ± 0.05mm ~ ± 0.03mm profiles le liphaephe.
Ha ho nepahala ha eona ho feta habeli boemo ba naha bo phahameng ka ho fetesisa, bo bitsoa profil e nyane (e nyane) ea aluminium ea boleng bo holimo, joalo ka mamello ea sebopeho sa ± 0.09mm, mamello ea botenya ba lebota ea ± 0.03mm ~ ± 0.01mm bakeng sa profil e nyane (e nyane) kapa phala.
