Lintlha Tse Amanang le ho Petsoha ha Plate ea Aluminium Nakong ea Ho Etsa
Aluminium poleiti e etsa mapetso ke taba e mahlonoko eo bahlahisi ba tobaneng le eona nakong ea ho kobeha, ho tsitsipana, le lits'ebetso tse tebileng, hangata e lebisang ho senyeheng ha lintho tse bonahalang, mefokolo ea sebopeho, le ho eketseha ha litšenyehelo tsa tlhahiso.
Hobaneng ha lipoleiti tsa aluminium li robeha nakong ea ho theha
Ho theha mapetsong ha se liphoso tse iketsahallang feela. Maemong a mangata a indasteri, li bakoa ke ho se lumellane pakeng tsa thepa ea lintho tse bonahalang le ho theha maemo. Lipoleiti tsa aluminium, ha e ntse e le bobebe ebile e sa bola, bonts'a mamello e fokolang ea khatello ha ba pepesehetse kabo e sa lokelang.
Litekanyo tsa bohlokoa tse susumetsang li kenyelletsa:
- Litšobotsi tsa metallurgic
- Moqapi oa mokhoa oa ho etsa
- Geometry ea lisebelisoa
- Ho tsitsa ha tlhahiso
Ho utloisisa lintlha tsena ho lumella baenjiniere ho bolela esale pele likotsi tsa ho phatloha pele ho tlhahiso ea bongata.
1. Lintho Tse Bonahalang Tse Susumetsang Boitšoaro ba ho Hlakola
1.1 Khetho ea Alloy le Microstructure
Limaraka tsa aluminium tse tlase-tlase ka kakaretso li fana ka sebopeho se betere ka lebaka la ductility e phahameng le kabo ea lijo-thollo tse tšoanang. Li-alloys tse matla haholo, ha e ntse e phahame ka sebopeho, li na le maikutlo a matle haholo ho tsitsipano nakong ea ho theha.
1.2 Boemo ba Bohale le Mechini
Bohale bo halefileng kapa bo thata ka mokhoa o itseng bo fana ka bolelele bo betere, ho fokotsa ho qaleha ha crack sebakeng se kobehang ka ntle.
Tafole 1: Alloy le Temper Impact ho Theha Sensitivity ea Crack
| Aluminium Alloy | Tloaelehileng Bohale | Kotulo Matla (MPa) | Emplation (%) | Crack Sensitivity |
|---|---|---|---|---|
| 1050 | O | 30-35 | ≥35 | E tlase haholo |
| 3003 | H14 | 110-130 | 15-20 | Tlase |

2. Ho theha Mekhahlelo ea Ts'ebetso e Etsang Mapheo
2.1 Nako e fokolang ea ho Kobela Radius
Ho sebelisa radius e kobehang e nyane ho feta boleng bo khothalelitsoeng ho baka khatello e feteletseng ea khoele e ka ntle, ho potlakisa ho qalisoa ha crack.
2.2 Ho theha lebelo le sekhahla sa khatello
Ho theha ka potlako ho eketsa khatello ea maikutlo sebakeng sa heno, ho fokotsa ho tšoana ha phallo ea lintho tse bonahalang.
2.3 Lubrication le Surface Friction
Mafura a sa lekaneng a phahamisa khanyetso ea likhohlano, ho thibela motsamao oa tšepe le ho eketsa monyetla oa ho robeha.
3. Moralo oa Tooling le Die Condition
Boleng ba lisebelisoa bo ama ka ho toba kabo ea khatello ea kelello nakong ea ho theha. Maqhubu a bohale, tumello e sa lekaneng, kapa ho roala ka holim'a metsi ho phahamisa likotsi tsa ho peperana haholo.
Tafole 2: Tooling Condition vs. Ho phatloha Monyetla (Papiso)
| Tooling Condition | Kabo ea Khatello | Metal Flow Stability | Cracking Kotsi |
|---|---|---|---|
| Optimized die radius | Uniform | E tsitsitseng | Tlase |
| Tokomane e fokolang ea lefu | Tsepamisitsoe maikutlo | E thibetsoe | Phahameng |
| Lefu le tsofetseng kapa le thata | E sa tloaelehang | E sa tsitsang | Phahameng haholo |
4. Indasteri Pale ea Thuto: Eco Alum Co., Ltd
Eco Alum Co., Ltd ke morekisi ea nang le boiphihlelo ba lipoleiti tsa aluminium tse shebaneng le lisebelisoa tsa maemo a holimo bakeng sa lits'ebetso tsa indasteri le lipalangoang.
Moralo oa morero
Moreki ea hlahisang liphaephe tsa motlakase o ile a ba le ho phatloha khafetsa nakong ea ho kobeha lipoleiti tsa aluminium ka li-angle tse ngata..
Mabaka a Motso a Tsebahala
- Bolelele bo sa tsitsang lipakeng tsa lihlopha
- Bohale bo thata ho feta tekano bakeng sa botebo ba ho bopa
- Ho hlokomolohuoa tsela e potolohang nakong ea moralo oa moralo
Lintlafatso tsa Setsebi
- Phokotso e laoloang ea rolling ho ntlafatsa sebopeho sa lijo-thollo
- Phetoho e fetotsoeng ho ntlafatsa ductility
- E fane ka likhothaletso tsa ho theha sebopeho ho moreki
Liphetho tse Lekanyetsoang
- Sekhahla sa petso se fokotsehile ka 62%
- Tahlehelo ea sekhechana e fokotsehile ho tloha 7% ho ea tlase 3%
- E ntlafalitse ho pheta-pheta ha tlhahiso ho pholletsa le tlhahiso
Nyeoe ena e tiisa hore taolo ea ho senya e ka finyelloa ka lisebelisoa tse hokahaneng le ts'ebetso ea ts'ebetso.
5. Maemo a Tloaelehileng a Kotsi e Phahameng
- Ho kobeha ha radius e thata ntle le ho phunya pele
- Ho taka ka botebo ka ho sebelisa bohale bo matla haholo
- Ho etsa mehato e mengata ntle le khatello ea maikutlo
- Ho etsa parallel to rolling direction
Ho qoba maemo ana ho ntlafatsa haholo ho theha litekanyetso tsa katleho.
LIPOTSO TSE BOTSOANG HANGATA (LBH)
Q1: Ho phatloha ho bonahala hang ka mor'a ho theha?
Eseng kamehla. Li-micro-cracks li ka ata hamorao nakong ea ho roala, kopano, kapa bophelo ba tšebeletso.
Q2: Na ho eketsa botenya ba poleiti ho felisa ho phatloha?
Che. Botenya ha bo lefelle ductility e sa lekaneng kapa radius e sa nepahalang ea sebopeho.
Q3: Ho bohlokoa hakakang mabapi le mokhoa oa ho thibela crack?
E bohlokoa haholo. Ho etsa perpendicular to rolling direction hangata ho fokotsa kotsi ea crack.
Q4: Na ho etsa mapatso ho ka boleloa esale pele pele ho tlhahiso?
Ho joalo. Teko ea tensile, teko ea kobeha, le ho etsa lipapiso ho ka khetholla likotsi tse ka bang teng.
Qetello
Ho thibela ho phatloha ha poleiti ea aluminium ho hloka mokhoa o akaretsang o kopanyang khetho ea alloy, ho laola bohale, Ho theha liparamente, le ho ntlafatsa lisebelisoa. Baetsi ba sebetsang le barekisi ba nang le boiphihlelo joalo ka Eco Alum Co., Ltd e fumana molemo o tiileng ka ho hokahanya ts'ebetso ea thepa le maemo a sebele a ho etsa.
