Chii chinonzi Aluminium extrusion?
Izvo zvinodiwa kuti uzive nezve Extrusion musati wabata Aluminium extrusion.Extrusion inzira inoshandiswa kugadzira zvinhu zveyakagadziriswa muchinjikwa-sectional profile nekusundira zvinhu kuburikidza nefa yeinodiwa muchinjiko-chikamu.Yayo miviri mikuru mabhenefiti pamusoro pemamwe maitiro ekugadzira ndiko kugona kwayo kugadzira yakaoma kwazvo muchinjikwa-zvikamu;uye nekushandisa zvinhu zvinogoneka, nekuti izvo zvinhu zvinosangana chete nekumanikidza uye kugera zvinonetsa.Inogadzirawo kupedzisa kwepamusoro uye inopa rusununguko rwakakura rwechimiro mukugadzira dhizaini.Extrusion inogona kuenderera (inoretically ichigadzira nekusingaperi zvinhu zvakareba) kana semi-inoenderera (inoburitsa zvidimbu zvakawanda).Inogona kuitwa nezvinhu zvinopisa kana kutonhora.Zvishandiso zvakajairika zvinosanganisira simbi, mapolymers, ceramics, kongiri, ivhu rekuenzanisira, uye chikafu.Zvigadzirwa zve extrusion zvinowanzonzi extrudates.Saka ikozvino isu tinonyanya kugovera ruzivo nezve Aluminium extrusion.
Kuti upedze iyo aruminiyamu extrusion, iwe unofanirwa kuve neinodiwa hardware mamiriro, senge extruding zvishandiso / extrusion michina, inofa uye mbishi zvinhu, aruminiyamu alloy iyo inoshandiswa kuburitsa mune extrudates.Isu tichapedza nguva yakawanda tichizivisa ruzivo nezve extruding michina / michina gare gare.Chekutanga pane zvese, isu tichava neruzivo rwemhando ipi yealuminium alloy inogona kushandiswa kugadzira extrusion.
JHmockup inotora matatu ekutanga aruminiyamu alloy zvinhu zvinonyanya kuuya kubva ku6000 akatevedzana kuzadzisa aluminium extrusion kugadzira panzvimbo yedu yekukurumidza prototyping yekugadzira.Chokwadi pane zvimwe alloy zvinhu zvinogona kushandiswa extrusion kubva aruminiyamu mhuri, pano isu chete kusuma matatu kiyi mhando aruminiyamu: Aluminium chiwanikwa 6005, Aluminium chiwanikwa 6063 uye Aluminium chiwanikwa 6463.
Aluminium Alloy 6005
Zvichienderana nesimba rakakura uye kusimba kuri nani kwe6000 akateedzana aruminiyamu alloys seAluminium alloy 6005, kune akawanda uye akawanda zvikamu uye zvigadzirwa zvakagadzirwa neextrusion.Hunhu hweiyi aluminium alloy inogona kushandiswa mumagadzirirwo anoda super quality corrosion resistance uye simba riri pakati nepakati.Imwe neimwe alloy ine huwandu hwezvinhu zvakasiyana-siyana, kusanganisira kuita kwayo panguva yeextrusion, machining uye kupedza.Nezvinhu zvakasiyana zvinowedzera kualuminium, isu tinogona kuva mukuwedzera kudzivirira kukoromoka nedhizaini uye kugadzira mibairo yepamusoro kana uchisarudza extruded aluminium alloy.
Aluminium Alloy 6005 zvinhu zvine yakanakisa extrusion zvivakwa.Nekuti ine huwandu hukuru hwesilicon element kuitira kuti igone kudzikisa tembiricha yekunyunguduka uye kuvandudza kugona kwayo kwekuwedzera.Iyo ine zvakare yakafanana yakaderera tensile uye goho simba kune aluminium 6061 alloy, asi iri nyore kugadzirwa uye ine yakakwirira simba zvivakwa.Aluminium Alloy 6005 zvakare ine zvimwe zvinochinjika/kukotama zvivakwa, izvo zvinoita kuti ive isiri iyo yakanakisa sarudzo yezvikumbiro zvingave zviri pasi pekuremerwa kana kuvhunduka.Iyi alloy inogona kugadzirwa uye kugadzirwa nedzimwe nzira, asi kupisa kunoderedza simba, saka chero basa rakasiyana rinoitwa zvakanakisisa kuburikidza nealuminium extrusion design pane kushanda kwechipiri.

Ndeapi marudzi emaumbirwo san anowedzerwa neAlluminium alloy material?
Kune matatu makuru mapoka e extruded shapes:
> Yakasimba, isina maburi akavharirwa kana maburi (kureva danda, danda, kana kona).
> Hollow, ine rimwe kana kupfuura void (kureva mativi kana rectangular chubhu).
> Semi-hollow, ine chidimbu chakavharirwa chisipo (kureva “C” chiteshi chine mukaha mudiki)
Kufa dhizaini yeAluminium extrusion
Iyo dhizaini yeiyo extruded profil ine mhedzisiro yakakura pakureruka kweextrusion.Iyo yakakura saizi ye extrusion inotarirwa nekutsvaga denderedzwa diki rinoenderana nechikamu-chikamu, icho chinonzi circumcircle.Iyi dhayamita, zvakare, inodzora saizi yefayiti inodiwa, iyo inozosarudza kana chikamu chacho chichakwana mumuchina wakapihwa.Semuyenzaniso, muchina mukuru anogona kubata 60 cm (24 mu) dhayamita kunze madenderedzwa aruminiyamu uye 55 masendimita (22 mukati) dhayamita simbi uye titanium.
Iko kuomarara kweiyo extruded profil inogona kuverengerwa nekuverenga iyo fomu factor, inova iyo nzvimbo yepamusoro inogadzirwa pane imwe unit mass extruded.Izvi zvinokanganisa mutengo wekushandisa pamwe nekumhanya kwekugadzira.Zvimedu zvakakora kazhinji zvinoda kuwedzera saizi yechidimbu.Kuti zvinhu zvifambe zvakanaka, kureba kwemakumbo hakufaniri kudarika kagumi.Kana zvikamu zvisingaenzaniswi, zvikamu zviri pedyo zvinofanira kunge zviri pedyo nehukuru hwakafanana sezvinobvira.Makona akapinza anofanira kudziviswa;aruminiyamu uye magnesium inofanira kuva neradius shoma ye 0.4 mm (1/64 in.), makona esimbi anofanira kuva 0.75 mm (0.030 in.), uye makona akatenderedzwa anofanira kuva 3 mm (0.12 mukati.).Tafura iri pazasi inoronga zvikamu zvishoma uye ukobvu hwezvinhu zvakasiyana-siyana.
