Cov yam ntxwv cuam tshuam rau txhuas phaj tawg thaum tsim
Aluminium phaj tsim cracking yog ib qho teeb meem tseem ceeb uas cov neeg tsim khoom tau ntsib thaum khoov, tau luam tawm, thiab kev ua haujlwm tob tob, feem ntau ua rau cov khoom pov tseg, yam ntxwv tsis xws luag, thiab nce nqi ntau lawm.
Yog vim li cas Aluminium Phaj Crack Thaum tsim
Kev tsim cov kab nrib pleb tsis yog qhov tsis xws luag. Nyob rau hauv feem ntau industrial mob, lawv tshwm sim los ntawm kev tsis sib haum xeeb ntawm cov khoom siv thiab cov txheej txheem tsim. Aluminium daim hlau, thaum lub teeb yuag thiab corrosion-resistant, ua rau muaj kev txwv tsis pub muaj kev kam rau siab thaum raug kev cuam tshuam tsis zoo.
Qhov tseem ceeb cuam tshuam qhov ntev muaj xws li:
- Metallurgical yam ntxwv
- Tsim cov txheej txheem tsim
- Tooling geometry
- Kev tsim khoom sib xws
Kev nkag siab txog cov xwm txheej no tso cai rau cov kws tshaj lij tuaj yeem kwv yees kev pheej hmoo tawg ua ntej ntau lawm.
1. Cov khoom siv uas cuam tshuam rau kev sib tsoo
1.1 Alloy Selection thiab Microstructure
Cov qib qis-alloy aluminium feem ntau muab kev tsim tau zoo dua vim tias muaj cov khoom siv ntau dua thiab cov khoom sib xws. High-lub zog alloys, thaum structurally superior, yog rhiab heev rau tensile hom thaum tsim.
1.2 Temper thiab Mechanical State
Annealed los yog ib nrab hardened tempers muab zoo elongation, txo qhov pib tawg ntawm qhov khoov sab nraud.
Lub rooj 1: Alloy thiab Temper cuam tshuam rau kev sib tsoo rhiab heev
| Aluminium Alloy | Common Temper | Yield zog (MPa) | Elongation (%) | Crack Sensitivity |
|---|---|---|---|---|
| 1050 | O | 30—35 | ≥35 | Tsawg heev |
| 3003 | H14 | 110-130 | 15-20 | Qi |
| 5052 | H32 | 190– 215 | 12-18 | Nruab nrab |
| 6061 | T6 | 240– 275 | 8-12 | Siab |
2. Tsim cov txheej txheem Parameter uas ua rau tawg
2.1 Yam tsawg kawg Bending Radius
Siv lub vojvoog dabtsi yog khoov me dua qhov kev pom zoo tsim kom muaj zog tensile ntau dhau ntawm cov fiber ntau, accelerating crack pib.
2.2 Kev sib sau ceev thiab lim tus nqi
Kev sib sau nrawm ua rau muaj kev sib txawv hauv cheeb tsam, txo cov khoom ntws uniformity.
2.3 Lubrication thiab nto Friction
Tsis txaus lubrication nce kev sib txhuam tsis kam, txwv tsis pub hlau txav thiab nce pob txha yuav tshwm sim.
3. Tooling Design thiab Die Condition
Tooling zoo ncaj qha cuam tshuam kev ntxhov siab faib thaum lub sij hawm tsim. Sharp tuag npoo, clearance tsis txaus, los yog nto hnav tseem ceeb elevate cracking txaus ntshai.
Lub rooj 2: Tooling Condition vs. Cracking Probability (Sib piv)
| Tooling condition | Kev Nyuaj Siab Distribution | Hlau Flow Stability | Cracking Risk |
|---|---|---|---|
| Optimized tuag radius | Cev khaub ncaws tseem ceeb | ruaj khov | Qi |
| Undersized tuag clearance | Nco ntsoov | Txwv tsis pub | Siab |
| Hnav los yog ntxhib tuag | Tsis zoo | Tsis ruaj khov | Siab heev |
4. Kev Tshawb Fawb Kev Lag Luam: Eco Alum Co., Ltd
Eco Alum Co., Ltd yog ib qho kev paub txog txhuas phaj tsum tsom rau kev tsim cov ntaub ntawv rau kev lag luam thiab kev thauj mus los.
Qhov project Background
Ib tus neeg siv khoom tsim hluav taws xob cov ntaub thaiv npog tau ntsib dua qhov tawg thaum lub sijhawm ntau lub kaum sab xis ntawm cov ntawv txhuas.
Keeb kwm ua rau pom
- Inconsistent elongation ntawm batch
- Over-hardened temper rau txoj kev tob
- Ignored dov kev taw qhia thaum lub sij hawm layout tsim
Kev txhim kho txuj ci
- Tswj dov txo kom zoo dua cov qauv nplej
- Kho annealing voj voog los txhim kho ductility
- Muab daim ntawv-orientation pom zoo rau cov neeg siv khoom
Kev ntsuas tau
- Crack tus nqi txo los ntawm 62%
- Cov khoom poob qis los ntawm 7% rau hauv qab 3%
- Txhim kho daim ntawv repeatability nyob rau hauv ntau lawm khiav
Cov ntaub ntawv no lees paub tias kev tswj kev tawg yog ua tiav los ntawm cov khoom sib koom ua ke thiab kev ua kom zoo dua qub.
5. Common High-Risk Forming Scenarios
- Tight-radius dabtsi yog khoov yam tsis muaj annealing ua ntej
- Sib sib zog nqus kos siv cov tempers siab
- Multi-kauj ruam ua tsis muaj kev ntxhov siab
- Tsim parallel rau dov kev taw qhia
Zam cov xwm txheej no ua rau muaj txiaj ntsig zoo rau kev ua tiav.
Cov Lus Nquag Nug (FAQ)
Qi1: Yog cracking ib txwm pom tam sim ntawd tom qab sib sau?
Tsis tas li. Micro-cracks tuaj yeem nthuav tawm tom qab thaum txheej txheej, kev sib dhos, los yog kev pab lub neej.
Q2: Ua kom phaj thickness tshem tawm kev tawg?
Tsis muaj. Thickness tsis them rau qhov tsis txaus ductility los yog tsis tsim nyog txoj kab uas hla.
Q3: Qhov tseem ceeb npaum li cas yog dov kev taw qhia hauv kev tiv thaiv tawg?
Tseem ceeb heev. Kev tsim cov perpendicular rau dov kev taw qhia feem ntau txo qhov kev pheej hmoo tawg.
Qi4: Kev tsim cov kab nrib pleb tuaj yeem kwv yees ua ntej ntau lawm?
Yog lawm. Kev ntsuas tensile, khoov kuaj, thiab tsim cov simulation tuaj yeem txheeb xyuas cov kev pheej hmoo.
