Kugadzirira nzira uye matambudziko ealuminium foam sandwich panels

Kugadzirira kwealuminium foam sandwich panelsyakakamurwa kuva mapoka maviri pamwe chete. Chikamu chekutanga ndechekugadzira aluminium foam kutanga, uye wozobatanidza furo realuminium nesimbi yepaneru nenzira dzakasiyana, senge simende yekubatanidza, pamusoro pemafuta ekupfapfaidza nzira, uye welding yekubatanidza. Rudzi rwechipiri nderokugadzirira muviri wakagara wealuminium foam sandwich panel, uye ipapo muviri wakagadzirirwa unopisa kuti ugadzire core layer foam, uye furo rinotonhodzwa mushure mekupedzwa kwefuro rinova aluminium foam sandwich panel. Inowanzo shandiswa nzira dzekugadzirira dzinosanganisira kupisa kudzvanya - upfu metallurgy foaming nzira, rolling - coating - foaming nzira, zvichingodaro.

1. Glued connection

Gluing inoreva nzira yekugadzira sandwich panels nekubatanidza aluminium foam kune simbi mapaneru ane zvinonamira zvakakodzera. Iyo gluing maitiro inotora iyo yemuviri yekubatanidza kugadzirira sandwich pani, uye iyo nzira ine zvakanakira maitiro akareruka uye yakakwirira yekugadzira chaiyo. Zvisinei, nekuda kwemaitiro ekugadzirisa kwepamusoro porosity yealuminium foam, kubviswa kwetsvina mumakomba ari pamusoro pealuminium foam inorema; mune iyi nzira yekubatanidza, pani uye core layer inonyanya kunamirwa paaperture prongs, uye iyo chaiyo inobudirira yekubatanidza nzvimbo idiki, iyo inoguma yakaderera kusungirirwa kwesimba re sandwich chimiro; iyo yakanamatira inokundikana pakupisa kwepamusoro kana munzvimbo dzakasimba dzakasimba, izvo zvinokonzera kuparadzaniswa kwepakati pepakati kubva panhizha uye kuparadzwa kwechimiro.

2. Welding connection

Welding nzira dzekugadzirira foam aluminium sandwich panels dzinosanganisira laser beam welding, ultrasonic torsion welding, uye brazing yekubatanidza. Laser beam welding iko kushandiswa kwelaser's high thermal simba kune panel zvinhu uye furo aluminium pamusoro pedenga rakanyunguduka, kutonhora mushure memubatanidzwa maviri pamwe chete, nzvimbo yewelding, uye welding sequence inoratidzwa muFigure 1. Laser beam welding ndeyechokwadi uye inogona zvinobudirira kudzora nzvimbo yakabatana yakanyunguduka. Kunyangwe iyi nzira inogona kuita kuenderera mberi kwekushanda, kushanda kwacho kwakadzikira, uye chigadzirwa chebhondi simba zvakare rakaderera. Nheyo ye ultrasonic torsion welding ndeyekubatanidza zvinhu zviviri pamwe chete ne ultrasonic simba. Zvisinei, iyi nzira inoda imwe nzvimbo yewelding, uye hazvibviri kupedzisa kusungirirwa kwezvinhu zvose zvakatarirwa, izvo zvinoderedza kushandiswa kweiyi nzira mukugadzirwa chaiko. Iyo brazing yekubatanidza inozokanganiswa neiyo oxidized layer yefoam aluminium, saka zvakakosha kubvisa iyo oxidized layer, uye kana uchishandisa brazing tekinoroji pasina brazing flux mukati.foam aluminiumsandwich panels, mamwe matanho ekurwisa-corrosion anofanirwa kuverengerwa kudzivirira zinc-based uye mamwe maalloys kubva pakusanganiswa nealuminium corrosion. Mukuwedzera, zvikamu zvakabatanidzwa nenzira iyi zvinongova negomba prongs, saka simba rezvisungo richaderedzwa.

3. Surface thermal spraying nzira

Nzira yekuputira kazhinji inoda hupamhi hwepamusoro pamusoro pechikamu, saka nzira yacho haina kukodzera kune mamwe maitiro akaoma. Thermal spraying ndeye tekinoroji yepamusoro, iyo inowanikwa nekunyungudusa waya kana hupfu. Iyi nzira inoshandisa jeti yemhepo kuti ikurumidze kunyunguduka uye kuiendesa kumusoro kwechikamu kuti chifukidzwe, zvichiita kuti kugadziriswa kwezvikamu zvine maumbirwo akaoma. Nenzira iyi, iyo inopisa sosi inowanzove yemagetsi arc. Nekudaro, iyi nzira yakaoma kuindasitiri nekuda kwekuoma kwemaitiro.

4. Kupisa kudzvanya - upfu metallurgy foaming nzira

Munzira iyi, iyo core layer poda inoshandiswa kupupuma inotanga kuiswa mupanera, vozoiswa muforoma pamwe chete, uye hydraulic press inoshandiswa kuisa kutonhora kwavari, mushure mezvo ma blanks anobatwa pa450 ℃ kweinenge 1 h uye wobva wadzvanywa kuti uwane ma blanks akagadzirwa anogona kushandirwa kupupa furo. Iyo preform inozopisa uye inopushwa muforoma yakavharwa, uye sandwich panel inowanikwa mushure mekutonhora. Kuvapo kwe mold mune iyi nzira kuchava nezvimwe zvisingakwanisi pahukuru hweakapedzwa aluminium foam sandwich panel.

5. Rolling-coating-foaming nzira

Iyi nzira ndiyo yepakutanga poda yekupupa nekushandisa kwakakodzera kutenderedza nzira yekugadzira iyo yakakosha zvinhu, mushure mepaneru uye yakafanogadzirirwa yepakati zvinhu zvekuumburudza, kupeta, kuwana mabheji akagadzirwa, achipupa mushure mekutonhora kuti awane chimiro chakanaka chesangweji. panel. Iyi nzira yekugadzirira yezvigadzirwa zvine simba rekubatanidza yakakwira inogona kuona kuenderera mberi kwekugadzira asi inoda kukurira matambudziko maviri ehunyanzvi: imwe kudiwa kwehupfu, uye yechipiri ndiyo inoshanda musanganiswa weiyo core material uye panel rolling.
