Kugwiritsiridwa ntchito kwa aluminium extrusion pakupanga zinthu ndi kupanga kwakula kwambiri m'zaka makumi angapo zapitazi.
Malinga ndi lipoti laposachedwa lochokeraTechnavio, pakati pa 2019-2023 kukula kwa msika wapadziko lonse wa aluminiyamu extrusion kudzakwera ndi Compound Annual Growth Rate (CAGR) pafupifupi 4%.
Mwina mudamvapo za kupanga izi ndipo mukudabwa kuti ndi chiyani komanso momwe zimagwirira ntchito.
Kodi Aluminium Extrusion ndi chiyani?
Aluminiyamu extrusion ndi njira yomwe aluminiyamu aloyi zinthu amakakamizika kudzera kufa ndi enieni mtanda-gawo mbiri.
Nkhosa yamphongo yamphamvu imakankhira aluminiyumu kudzera mu ufa ndipo imatuluka kuchokera ku bulauni. Ikatero, imatuluka mu mawonekedwe ofanana ndi ufa ndipo imakokedwa motsatira njira yothamanga. table.Pa mlingo wofunikira, ndondomeko ya aluminium extrusion ndiyosavuta kumvetsetsa.
Pamwambapa pali zojambula zomwe zimagwiritsidwa ntchito popanga ma dies ndipo pansi pali mafotokozedwe a momwe ma aluminium omalizidwa adzawonekera.
Maonekedwe omwe timawawona pamwambawa ndi ophweka, koma njira yowonjezera imalola kuti pakhale mawonekedwe omwe ali ovuta kwambiri.

Tiyeni tiwone m'munsimu Aluminium Art.Sichojambula chokongola chokha, chomwe chimaphatikizapo masitepe ambiri a aluminiyamu extrusion.(mold making-aluminium liquid-aluminium bar-aluminium extrusion-surface treatment)
1):The Extrusion Die Yakonzedwa ndikusunthira ku Extrusion Press
Choyamba, kufa kozungulira kumapangidwa kuchokera kuchitsulo cha H13.Kapena, ngati imodzi ilipo kale, imakokedwa kuchokera kunkhokwe monga momwe mukuwonera pano.
Isanafike extrusion, ufa uyenera kutenthedwa pakati pa 450-500 madigiri celsius kuti uthandizire kukulitsa moyo wake ndikuwonetsetsa kuti chitsulo chikuyenda.
Ikatenthedwa ndi kufa, imatha kuyikidwa mu makina osindikizira a extrusion.
2):Billet ya Aluminiyamu Imatenthedwa Asanatuluke
Kenako, chipika cholimba cha cylindrical aloyi cha aluminiyamu, chotchedwa billet, chimadulidwa kuchokera ku chipika chachitali cha aloyi.
Imatenthedwa mu uvuni, monga iyi, mpaka pakati pa 400-500 digiri Celsius.
Izi zimapangitsa kuti zisawonongeke mokwanira kuti zitheke kutulutsa koma osasungunuka.
3) Billet imasamutsidwa ku Extrusion Press
Billet ikatenthedwa, imasamutsidwa pamakina kupita ku makina osindikizira a extrusion.
Isanakwezedwe pa makina osindikizira, mafuta odzola (kapena otulutsa) amawapaka.
Wothandizira kumasulidwa amagwiritsidwanso ntchito pa nkhokwe ya extrusion, kuteteza billet ndi nkhosa kuti zisagwirizane.
4)Ram Imakankhira Zinthu za Billet mumtsuko
Tsopano, billet yosasunthika imakwezedwa mu makina osindikizira, pomwe hydraulic ram imagwiritsa ntchito mpaka matani 15,000 akukakamiza.
Pamene nkhosa yamphongo imagwiritsa ntchito mphamvu, billet imakankhira mu chidebe cha makina osindikizira a extrusion.
Zinthuzo zimakulitsa kudzaza makoma a chidebecho
5)Zinthu Zowonjezera Zimatuluka Kudzera mu Die
Pamene zinthu za alloy zimadzaza chidebecho, tsopano zikukanikizidwa ndi extrusion die.
Ndi kukanikiza kosalekeza kwa icho, zinthu za aluminiyamu zilibe kwina kopitira kupatulapo potsegula (ma) mu kufa.
Imatuluka kuchokera pachitseko cha kufa mu mawonekedwe a mawonekedwe opangidwa bwino.
6)Ma Extrusions Amatsogozedwa Patebulo Lothamangitsidwa ndikuzimitsidwa
Pambuyo potulukira, extrusion imagwidwa ndi chokoka, monga chomwe mukuchiwona apa, chomwe chimatsogolera patebulo lothamanga pa liwiro lomwe limagwirizana ndi kutuluka kwake kuchokera ku makina osindikizira. ” kapena kuziziritsidwa mofanana ndi madzi osamba kapena ndi mafani pamwamba pa tebulo.
7)Zowonjezera zimamengedwa mpaka kutalika kwa Table
Extrusion ikafika kutalika kwa tebulo lonse, imamengedwa ndi macheka otentha kuti iwalekanitse ndi njira ya extrusion.
Pa sitepe iliyonse ya ndondomekoyi, kutentha kumagwira ntchito yofunikira.
Ngakhale kuti extrusion inazimitsidwa atatuluka m'manyuzipepala, sichinakhazikike bwino.
8)Ma Extrusions amawotchedwa mpaka Kutentha kwa Zipinda
Pambuyo pakumeta ubweya, ma extrusions a kutalika kwa tebulo amasamutsidwa mwamakina kuchokera patebulo lothamanga kupita patebulo lozizirira, monga momwe mukuwonera pano.Machuniwa azikhala pamenepo mpaka atafika kutentha.
Akatero, adzafunika kutambasulidwa.
Ma Extrusions amawotchedwa mpaka Kutentha kwa Zipinda
Pambuyo pakumeta ubweya, ma extrusion a kutalika kwa tebulo amasamutsidwa mwamakina kuchokera pa tebulo lothamanga kupita pa tebulo lozizirira, monga momwe mukuwonera pano.
Ma profaili azikhala pamenepo mpaka atafika kutentha.
Akatero, adzafunika kutambasulidwa.
9)Zowonjezera zimasunthidwa kupita ku Stretcher ndikuwongoleredwa kumayendedwe
Kupotokola kwina kwachilengedwe kwachitika mumbiri ndipo izi zikuyenera kukonzedwa.Kukonza izi, amasunthidwa ku machira. Mbiri iliyonse imagwiridwa mwamakina mbali zonse ziwiri ndikukokedwa mpaka itawongoka bwino ndipo yabweretsedwa mwatsatanetsatane.
10)Zowonjezera zimasunthidwa ku Finish Saw ndikudula mpaka kutalika
Ndi ma extrusions kutalika kwa tebulo tsopano mowongoka ndikugwira ntchito mokwanira, amasamutsidwa ku tebulo la macheka.
Apa, amachekedwa mpaka kutalika kwake komwe kumadziwika kale, nthawi zambiri amakhala pakati pa 8 ndi 21 m'litali.Panthawi imeneyi, katundu wa extrusions amafanana ndi mkwiyo.
Chimachitika N'chiyani Kenako?
Kutsirizitsa Pamwamba: Kupititsa patsogolo Mawonekedwe ndi Kuteteza Kuwonongeka
Zifukwa ziwiri zazikuluzikulu zoganizira izi ndikuti zimatha kukulitsa mawonekedwe a aluminiyamu komanso zimatha kukulitsa dzimbiri.Koma palinso mapindu ena.
Mwachitsanzo, njira ya anodization imakulitsa kusanjikiza kwachitsulo komwe kumachitika mwachilengedwe, kumapangitsa kuti chitsulocho chisawonongeke komanso kupangitsa kuti chitsulocho zisamva kuvala, kumapangitsa kuti pakhale mpweya wabwino, ndikupatsanso porous pamwamba yomwe imatha kulandira utoto wamitundu yosiyanasiyana.
Njira zina zomaliza monga kujambula, zokutira ufa, sandblasting, ndi sublimation (kupanga mawonekedwe a nkhuni), zitha kuchitidwanso.
Aluminiyamu extrusion ndi njira yopangira magawo okhala ndi mbiri yapakatikati pokankhira zinthu zotenthetsera za alloy kudzera pa die.It ndi Njira Yofunika Yopanga.
