Litlaleho tsa aluminium li sebelisoa haholo e le lisebelisoa tsa ts'ehetso, tse kang liforeimi tsa lisebelisoa, meeli, maballo, li-brackets, joalo-joalo Palo ea deformation e bohlokoa haholo ha u khetha litlaleho tsa aluminium. Li-profiles tsa aluminium tse nang le botenya bo fapaneng ba marako le likarolo tse fapaneng tsa sefapano li na le mefokolo e fapaneng ea khatello ea maikutlo.
Mokhoa oa ho bala matla a ho jara liprofaele tsa aluminium tsa indasteri? Re hloka feela ho tseba ho bala deformation ea profiles ea aluminium ea indasteri. Ka ho tseba deformation ea profiles ea aluminium ea indasteri, re ka boela ra bala bokhoni ba ho jara li-profiles.
Joale u ka bala deformation joang ho latela matla a profil?
Ha re qale ka ho sheba mekhoa ea mantlha ea ho lokisa li-profiles tsa aluminium. Ho na le mefuta e meraro: e tsitsitseng ka lehlakoreng le leng, e tšehetsoeng ka mahlakoreng ka bobeli, 'me e tsitsitse ka bobeli. Mekhoa ea lipalo bakeng sa matla le deformation ea mekhoa ena e meraro ea ho lokisa e fapane.
Ha re qale ka ho sheba mokhoa oa ho bala deformation ea profiles ea aluminium tlas'a mojaro o tsitsitseng:
Lintlha tse ka holimo ke liforomo tsa ho bala deformation ea static load ha qetello e le 'ngoe e tsitsitse, lipheletsong ka bobeli li tšehetsoa, 'me lipheletsong ka bobeli li tsitsitse. E ka bonoa ho tsoa ho foromo ea hore palo ea deformation e kholo ka ho fetisisa ha qetello e le 'ngoe e tsitsitse, e lateloa ke tšehetso lipheletsong tse peli,' me deformation e nyenyane ka ho fetisisa ke ha lipheletso ka bobeli li tsitsitse.
Ha re shebeng mokhoa oa ho bala deformation ntle le moroalo:
Khatello e phahameng e lumelletsoeng ea profil ea aluminium:
Ho feta khatello ena ho ka etsa hore profil ea aluminium e robehe kapa e robehe.
m: boholo ba mohala oa profil ea aluminium (kg/cm3)
F: Mojaro (N)
L: Aluminium profile bolelele
E: Modulase oa khase (68600N/mm2)

Fana ka mohlala
E ka holimo ke mokhoa oa ho bala bakeng sa deformation ea matla ea profiles ea aluminium ea indasteri. Ho nka mohlala oa profil ea aluminium ea 4545, re se re ntse re tseba hore bolelele ba profil ea aluminium ke L = 500mm, mojaro ke F = 800N (1kgf = 9.81N), 'me lipheletsong ka bobeli li tšehetsoa ka mokhoa o tsitsitseng, ebe palo ea deformation ea aluminium profil. = mokhoa oa ho bala oa matla a profil ea aluminium ea indasteri ke: mokhoa oa ho bala ke: deformation amount δ = (800×5003) / 192×70000×15.12×104≈0.05mm. Ena ke palo ea deformation ea profil ea aluminium ea indasteri ea 4545.
Ha re tseba deformation ea profiles ea aluminium ea indasteri, re beha bolelele le deformation ea profiles ka mokhoa oa ho fumana matla a ho beha. Ho latela mokhoa ona, re ka fana ka mohlala. Palo ea ho jara meroalo ea 1 meter 1 meter 1 metres e sebelisa li-profiles tsa aluminium tsa indasteri tsa 2020 e batla e bonts'a hore matla a ho jara mojaro ke 20KG. Haeba foreimi e katoa, matla a ho jara mojaro a ka eketsoa ho 40KG.
Tafole ea tlhahlobo e potlakileng ea Aluminium profil
The aluminium profile deformation quick check table e sebelisoa haholo-holo ho hlalosa chelete ea deformation e fihletsoeng ke litlaleho tsa aluminium tsa litlhaloso tse fapaneng tlas'a tšusumetso ea matla a ka ntle tlas'a mekhoa e fapaneng ea ho lokisa. Chelete ena ea deformation e ka sebelisoa e le tšupiso ea linomoro bakeng sa thepa ea 'mele ea foreimi ea profil ea aluminium; baqapi ba ka sebelisa setšoantšo se latelang ho bala ka potlako deformation ea profiles ea aluminium ea litlhaloso tse fapaneng linaheng tse fapaneng;
Lethathamo la mamello ea boholo ba profil ea aluminium
Sebaka sa mamello ea aluminium profile torsion
Aluminium profil transverse straight line tolerance
Aluminium profil longitudinal straight line tolerance
Aluminium profil angle tolerance
Ka holimo re thathamisitse mefuta e tloaelehileng ea mamello ea li-profile tsa aluminium ka botlalo mme ra fana ka lintlha tse qaqileng, tseo re ka li sebelisang e le motheo oa ho tseba hore na li-profiles tsa aluminium ke lihlahisoa tse tšoanelehang. Bakeng sa mokhoa oa ho lemoha, ka kopo sheba setšoantšo sa schematic se ka tlase.
