1 Kushandiswa kwealuminium alloy muindasitiri yemotokari
Parizvino, chikamu che12% kusvika 15% chearuminiyamu inoshandiswa pasi rose inoshandiswa neindasitiri yemotokari, nedzimwe nyika dzakabudirira dzinopfuura 25%. Muna 2002, indasitiri yese yemotokari yeEurope yakadya anopfuura miriyoni 1.5 metric matani ealuminium alloy mugore. Anosvika mazana maviri nemakumi mashanu ezviuru matani akashandiswa kugadzira muviri, mazana masere ezviuru zvematani ekugadzira mota yekufambisa hurongwa, uye imwezve mazana mana nemakumi maviri nesere,000 metric matani ekugadzira mota kutyaira uye masisitimu ekumisa. Zviripachena kuti indasitiri yekugadzira mota yave mutengi mukuru wealuminium zvinhu.
2 Zveunyanzvi Zvinodikanwa zveAluminium Stamping Sheets muStamping
2.1 Kugadzira uye Kufa Zvinodiwa zveAluminium Sheets
Nzira yekugadzira aluminium alloy yakafanana neyakajairika inotonhora-yakakungurutswa mashiti, ine mukana wekudzikisa tsvina uye aluminium scrap generation nekuwedzera maitiro. Nekudaro, pane misiyano mune zvinodiwa kufa zvichienzaniswa neinotonhora-yakakungurutswa mashiti.
2.2 Kuchengeta Kwenguva Yakareba KweAluminium Sheets
Mushure mekuchembera kuoma, simba regoho realuminium mapepa rinowedzera, richideredza kumucheto-kuumba processability. Paunenge uchigadzira inofa, funga nezvekushandisa zvinhu zvinosangana nepamusoro maratidziro ezvinodiwa uye itisa yekugonesa simbiso isati yagadzirwa.
Mafuta anotambanudza / ngura ekudzivirira anoshandiswa pakugadzira anowanzo vhiringika. Mushure mekuvhura pepa rekurongedza, rinofanira kushandiswa nekukasira kana kucheneswa uye kuzorwa mafuta isati yadhinda.
Iyo yepamusoro inotarirwa kune oxidation uye haifanirwe kuchengetwa pachena. Special manejimendi (packaging) inodiwa.
3 Zveunyanzvi Zvinodikanwa zveAluminium Stamping Sheets muWelding
Iwo mahombe ekugadzira maitirwo panguva yekuunganidzwa kwealuminum alloy miviri anosanganisira resistance welding, CMT inotonhora transition welding, tungsten inert gas (TIG) welding, riveting, punching, uye kugaya/kupolishing.
3.1 Welding pasina Riveting yeAluminium Sheets
Aluminium sheet components pasina riveting inoumbwa nekutonhora extrusion yeaviri kana kupfuura akaturikidzana emarata esimbi achishandisa midziyo yekumanikidza uye yakakosha mold. Iyi nzira inogadzira yakamisikidzwa mapoinzi ekubatanidza neimwe tensile uye shear simba. Ukobvu hwekubatanidza mapepa hunogona kunge hwakafanana kana hwakasiyana, uye anogona kuve neadhesive layers kana mamwe epakati akaturikidzana, aine zvinhu zvakafanana kana zvakasiyana. Iyi nzira inoburitsa zvakanaka zvinongedzo pasina kudiwa kweaya kubatanidza.
3.2 Resistance Welding
Parizvino, aluminium alloy resistance welding inowanzoshandisa yepakati-frequency kana yakakwira-frequency resistance welding process. Iyi welding process inonyungudutsa base simbi mukati medhayamita yeiyo welding electrode munguva pfupi yakanyanyisa kugadzira dziva re weld,
welding makwapa anokurumidza kutonhora kuti aumbe zvinongedzo, aine mashoma mikana yekugadzira aluminium-magnesium guruva. Utsi huzhinji hunogadzirwa hunosanganisira oxide particles kubva pamusoro pesimbi uye kusvibiswa kwepamusoro. Kufefetedza kwenzvimbo kunopihwa panguva yewelding kuti ikurumidze kubvisa zvimedu izvi mumhepo, uye pane kushomeka kweguruva realuminium-magnesium.
3.3 CMT Cold Transition Welding uye TIG Welding
Aya maitiro maviri ewelding, nekuda kwekuchengetedzwa kweinert gasi, anogadzira madiki ealuminium-magnesium metal particles pakupisa kwakanyanya. Izvi zvimedu zvinogona kupfachukira munzvimbo yekushanda pasi pechiito chearc, zvichiunza njodzi yealuminium-magnesium guruva rinoputika. Naizvozvo, kungwarira uye matanho ekudzivirira kuputika kweguruva uye kurapwa zvakakosha.
4 Zveunyanzvi Zvinodikanwa zveAluminium Stamping Sheets muEdge Rolling
Musiyano uripo pakati pealuminium alloy edge rolling uye yakajairwa inotonhora-yakatenderedzwa pepa kuchinjika yakakosha. Aluminium ine ductile shoma pane simbi, saka kumanikidza kwakanyanya kunofanirwa kudzivirirwa panguva yekukunguruka, uye kumhanya kwekukunguruka kunofanirwa kunge kuri kunonoka, kazhinji 200-250 mm/s. Imwe neimwe kona inotenderedza haifanirwe kudarika 30 °, uye V-yakaita kukunguruka kunofanirwa kudzivirirwa.
Zvinodiwa tembiricha yealuminium alloy rolling: Inofanirwa kuitwa pa20 ° C tembiricha yekamuri. Zvikamu zvinotorwa zvakananga kubva kunotonhora kuchengetedza hazvifanirwe kuiswa pasi pemupendero rolling nekukurumidza.
5 Mafomu uye Hunhu hweEdge Rolling yeAluminium Stamping Sheets
5.1 Mafomu eEdge Rolling yeAluminium Stamping Sheets
Kukunguruka kwakajairika kune matanho matatu: kutanga-kutenderedza, yechipiri pre-kukungurusa, uye yekupedzisira kukunguruka. Izvi zvinowanzo shandiswa kana pasina chakananga simba rinodiwa uye ekunze ndiro flange angles zvakajairika.
European-style rolling ine matanho mana: yekutanga pre-kukungurukira, yechipiri pre-kukungurukira, yekupedzisira kukunguruka, uye European-maitiro ekukunguruka. Izvi zvinowanzo shandiswa pakukunguruka-kurebesa, senge kumberi nekumashure. European-style rolling inogonawo kushandiswa kuderedza kana kubvisa kuremara kwepamusoro.
5.2 Hunhu hweEdge Rolling yeAluminium Stamping Sheets
Kune aluminium component rolling equipment, mold yepasi nekuisa block inofanira kukwenenzverwa uye kuchengetedzwa nguva dzose ne800-1200# sandpaper kuona kuti hapana zvisaririra zvealuminium zviri pamusoro.
6 Zvakasiyana Zvinokonzeresa Kukanganisa Kunokonzerwa neEdge Rolling yeAluminium Stamping Sheets
Zvakasiyana-siyana zvinokonzeresa kukanganisa kunokonzerwa nekutenderedza kwearuminiyamu zvikamu zvinoratidzwa mutafura.
7 Unyanzvi Zvinodiwa Pakupfekedza Aluminium Stamping Sheets
7.1 Misimboti uye Migumisiro Yemvura Yekugeza Passivation yeAluminium Stamping Sheets
Mvura yekugeza passivation inoreva kubvisa iyo yakasikwa oxide firimu uye mafuta mavara pamusoro pearuminiyamu zvikamu, uye kuburikidza nemakemikari reaction pakati pealuminium alloy uye ane acidic mhinduro, kugadzira dense oxide firimu pane workpiece pamusoro. Iyo oxide firimu, mavara emafuta, welding, uye adhesive bonding pamusoro pezvikamu zvealuminium mushure mekutsika zvese zvine chekuita. Kuti uvandudze kusungirirwa kwekunamatira uye welds, kemikari inoshandiswa kuchengetedza hukama hunogara kwenguva refu uye kuramba kugadzikana pamusoro pepamusoro, kuwana zviri nani welding. Naizvozvo, zvikamu zvinoda laser welding, inotonhora simbi yekuchinja welding (CMT), uye mamwe maitirwo ewelding anofanirwa kushambidzwa nemvura.
7.2 Kuyerera Kwemvura Yekugeza Passivation yeAluminium Stamping Sheets
Iyo yekugezesa mvura yekugezera midziyo ine nzvimbo yekudzikisa, nzvimbo yekugezesa mvura yeindasitiri, nzvimbo yekupfuura, nzvimbo yekugeza mvura yakachena, nzvimbo yekuomesa, uye exhaust system. Zvikamu zvealuminium zvinogadziriswa zvinoiswa mubhasiki rekugeza, zvakagadziriswa, uye zvinodzikiswa mutangi. Mumatangi ane zvakasiyana-siyana zvinonyungudutsa, zvikamu zvinoramba zvichicheneswa nemhinduro dzose dzekushanda mutangi. Ese matangi akashongedzerwa nemapombi ekutenderera uye nozzles kuti ave nechokwadi chekuchenesa yunifomu yezvikamu zvese. Mvura yekugeza passivation process inoyerera sezvinotevera: degreasing 1→ degreasing 2→inogeza mvura 2→inogeza mvura 3→ passivation→inogeza mvura 4→kugeza mvura 5→kugeza mvura 6→kuomesa. Aluminium castings inogona kusvetuka kugeza mvura 2.
7.3 Drying process yeWash yemvura Passivation yeAluminium Stamping Sheets
Zvinotora anenge maminetsi manomwe kuti chikamu chekushisa chisimuke kubva mukamuri tembiricha kusvika 140°C, uye nguva shoma yekurapa yekunamira maminetsi makumi maviri.
Zvikamu zvealuminium zvinosimudzwa kubva mukamuri tembiricha kusvika pakubata tembiricha mukati memaminitsi gumi, uye nguva yekubata yealuminium ingangoita maminetsi makumi maviri. Mushure mekubata, inotonhodzwa kubva pakudziya kwekuzvibata kusvika ku100 ° C kwemaminitsi manomwe. Mushure mekubata, inotonhodzwa kusvika kune tembiricha yekamuri. Naizvozvo, iyo yose yekuomesa maitiro ealuminium zvikamu maminetsi makumi matatu nemanomwe.
8 Mhedziso
Mota dzemazuvano dziri kufambira mberi dzichienda kwakareruka, kumhanya-mhanya, kuchengetedzeka, kugadzika, kudhura, kuburitsa mhepo yakaderera, uye nzira dzinoshanda nesimba. Kuvandudzwa kweindasitiri yemotokari kwakabatana zvakanyanya nekushanda kwesimba, kuchengetedza kwezvakatipoteredza, uye kuchengetedzwa. Nekuwedzera kwekuziva kwekuchengetedzwa kwezvakatipoteredza, aluminium mapepa zvinhu zvine zvakanakira zvisingaenzaniswi mumutengo, tekinoroji yekugadzira, kuita kwemakanika, uye kusimudzira kwakasimba zvichienzaniswa nezvimwe zvinhu zvisingaremi. Naizvozvo, aruminiyamu alloy inozove yakasarudzika huremu zvinhu muindasitiri yemotokari.
