Lolu hlobo lomkhiqizo lunokwakheka okukhethekile, ubukhulu obuncanyana odongeni, isisindo seyunithi yokukhanya, nezidingo eziqinile kakhulu zokubekezelela. Imikhiqizo enjalo ivame ukubizwa ngokuthi ukunemba kwe-aluminium alloy (noma ukunemba kwe-Ultra-), kanye nobuchwepheshe bokukhiqiza imikhiqizo enjalo kubizwa ngokuthi ukunemba. (noma ukucaciswa kwe-ultra-ukucacisa).
Izici eziphambili ze-aluminium alloy ngokunemba ekhethekile (noma ukucaciswa kwe-Ultra-) yilezi:
. Nezintambo, ezibandakanya i-alloy ehlukahlukene kanye nesimo. Ngenxa yesigaba sayo esincane sesiphambano, ubukhulu obuncanyana odongeni, isisindo esikhanyayo, namabheji amancane, ngokuvamile akukulula ukuhlela ukukhiqizwa.
. Indawo engaphezulu kwevolumu yeyunithi ngayinye inkulu, futhi ubuchwepheshe bokukhiqiza bunzima.
(3) Isicelo esibanzi, ukusebenza okukhethekile nezidingo ezisebenzayo. Ukuze uhlangabezane nezidingo zokusetshenziswa komkhiqizo, izifunda eziningi ze-alloy zikhethiwe, zimboze cishe wonke ama-alloys kusuka kuchungechunge olungu-1
. .
5) Ukunemba okunobukhulu kanye nezidingo zokubekezelela kwejometri ziqine kakhulu. Ngokuvamile, ukubekezelela kwamaphrofayli anengqondo we-aluminium alloy anengqondo angaphezu kokuphindwe kabili njengento ekhethekile yokubekezelela ibanga elikhethekile ku-jis, GB, kanye namazinga we-ASTM. Ukubekezelelwa kodonga kodonga ngokunemba okujwayelekile ama-aluminium alloy amaphrofayli kuyadingeka ukuba abe phakathi kwe- Isibonelo, isisindo sephrofayili yokunemba ye-aluminium esetshenziselwa i-Potentiometer yi-30g / m, futhi uhla lokubekezelela losayizi wesigaba yi- ± 0.07mm. Ukubekezelelwa kosayizi okuphambene nesigaba sokunemba ama-aluminium amaphrofayli ama-looms yi- ± 0.04mm, ukuphambuka kwe-angle kungaphansi kuka-0.5 °, kanye ne-degree eboshiwe ngu-0.83 × l. Esinye isibonelo ukunemba okuphezulu kwe-Ultra-Fight Tube ephakeme yezimoto, ngobubanzi obungama-20mm, ukuphakama okungu-1.7mm, ukushuba udonga lwe-0.17 ± 0.01mm, kanye namaphrofayili ajwayelekile we-aluminium alluy alloy.
(6) Inokuqukethwe okuphezulu kwezobuchwepheshe futhi kunzima kakhulu ukukhiqiza, futhi kunezidingo ezikhethekile zemishini yokukhishwa, amathuluzi, ama-billts nezinqubo zokukhiqiza. Umdwebo 1 uyisibonelo sesigaba samaphrofayili athile amancane we-aluminium alloy.
2. Ukuhlukaniswa kwe-aluminium alloy izinto ezikhethekile zokuqamba
Ukunemba noma ukunemba kwe-aluminingum Alloy extrusions kusetshenziswa kabanzi kumathuluzi we-elekthronikhi, imishini yokusika kanye nokuvikela amasosha, izinsimbi zomshini ezinobumba, imishini yenuzi, i-aeroace, imboni yenuzi, amandla angaphansi kanye nemikhumbi, amandla angaphansi kanye nemikhumbi, amandla angaphansi komhlaba, Izimoto namathuluzi okuhamba, imishini yezokwelapha, amathuluzi we-Hardware, ukukhanyisa, izithombe kanye nemishini ye-elekthronikhi. Ngokuvamile, ukunemba noma ukunemba okunembile oku-aluminium alloy kungahlukaniswa ngezigaba ezimbili ngokuya ngezimpawu zazo zokubukeka: isigaba sokuqala singamaphrofayli anobukhulu obuncane. Lolu hlobo lwephrofayili lubizwa nangokuthi iphrofayili ye-Ultra-encane noma i-mini-shape. Usayizi wayo ophelele uvame ukuvama amamitha ambalwa kuphela, ubukhulu obuncane bodonga bungaphansi kwe-0.5mm, kanti isisindo seyunithi singama-gramu amaningana kuya kumashumi ama-gramu ngemitha ngayinye. Ngenxa yobukhulu babo obuncane, ukubekezelelana okuqinile kuvame ukudingeka kubo. Isibonelo, ukubekezelelana kwezici zesigaba sesigaba kungaphansi kwe- ± 0.05mm. Ngaphezu kwalokho, izidingo zokuqonda kanye ne-tersorion yemikhiqizo eyengeziwe nazo ziqinile.
Olunye uhlobo ngamaphrofayli angasincane kakhulu kusayizi wesigaba sesigaba kepha adinga ukubekezelelana okuqinile, noma amaphrofayli anesimo esiyinkimbinkimbi sesigaba kanye nosayizi odongeni oluncane yize usayizi odongeni oluncane yize usayizi odongeni oluncane yize usayizi odongeni oluncane yize usayizi odongeni oluncane yize usayizi odongeni oluncane yize usayizi odongeni olubucayi yize usayizi odongeni oluncane yize usayizi odongeni oluncane yize usayizi odongeni oluncane yize usayizi odongeni oluncane yize usayizi odongeni oluncane yize usayizi odongeni oluncane yize usayizi odongeni olubucayi yize usayizi odongeni oluncane yize usayizi odongeni oluncane yize usayizi wesigaba sesigaba mkhulu. Umdwebo 2 ukhombisa i-tube ebunjiwe ekhethekile (i-aluminum ephuthumayo yezimboni) ekhishwe yinkampani yaseJapan kwi-16.3mn avundlile hydraulic Press nge-split ekhethekile efa nge-courenser yezimoto ezinomoya. Ubunzima bokwakhiwa kwe-extrusion kwalolu hlobo lwephrofayili akubangaphansi kolunye uhlobo lwephrofayili ye-Ultra-encane. Amaphrofayili ancishisiwe anosayizi omkhulu wesigaba futhi izidingo eziqinile zokubekezelela ezingadingi kuphela ubuchwepheshe obuthuthukile bokubuchwepheshe, kepha nako dinga ubuchwepheshe obuqinile bokuphathwa kwenqubo yonke yokukhiqiza kusuka ku-Blank to Broad Product.
Kusukela ekuqaleni kweminyaka yama-1980s, ngenxa yokusetshenziswa okungokoqobo kokuvumelanisa ubuchwepheshe obuqhubekayo bokukhishwa kanye kanye nokuthuthukiswa kobuchwepheshe bezimboni, ukukhishwa kwamaphrofayili amancane nakwamancane e-Ultra sekuthuthukile ngokushesha. Kodwa-ke, ngenxa yezizathu ezahlukahlukene ezinjengokulinganiselwa kwemishini, izidingo zekhwalithi yomkhiqizo, kanye nentuthuko kubuchwepheshe obukhulu bokukhishwa, ukukhiqizwa kwamaphrofayili amancane emishini evamile yokukhishwa kusala inani elikhulu. Umdwebo 2 ukhombisa amaphrofayili anembile wokukhishwa kokuhlukaniswa okujwayelekile kufa. Impilo yesikhunta (ikakhulukazi amandla futhi igqoke ukumelana kwebhuloho le-shunt kanye nomugqa wokubumba) nokugeleza kwezinto ngesikhathi sokukhishwa kube yizinto eziphambili ezithinta umkhiqizo wazo. Lokhu kungenxa yokuthi lapho ukhipha iphrofayili, ubukhulu bobumba obubi buncane futhi ukwakheka kuyinkimbinkimbi, futhi amandla nokuvimbela ukumelana kuyizinto ezibalulekile ezithinta impilo yesikhunta, inhloso yokubumba ithinta ngqo izindleko zokukhiqiza. Ngakolunye uhlangothi, amaphrofayli amaningi okunemba anezindonga ezincanyana nezimo eziyinkimbinkimbi, futhi ukugeleza kwezinto ezisetshenziswayo ngesikhathi senqubo yokukhishwa kuthinta ngqo ukwakheka kwe-Shape nokunemba kwamaphrofayili.
Ukuze uvikele ifilimu le-oxide kanye namafutha ebusweni be-billet kusuka ku-Flued ungene kulo mkhiqizo futhi uqinisekise i-Uniform kanye ne-BillET ENGCOLODIWE KWAMANDLA, futhi Ngemuva kwalokho faka ngokushesha emgqonyeni wokukhishwa ukuze ukhishwe. Ngasikhathi sinye, i-gasket esetshenzisiwe kufanele igcinwe ihlanzekile ukuvikela uwoyela nokungcola ekuthoseni i-gasket ngesikhathi senqubo yokususa ingcindezi eyeqile ngemuva kokukhishwa okukodwa.
Ngokusho kwe-Quinsional ukunemba kanye nokwakheka kanye nokubekezelela isikhundla, ukucaciswa okukhethekile kwe-Aluminium Alloy kungahlukaniswa ngamaphrofayili akhethekile we-aluminium alloy kanye namaphrofayili aphezulu we-aluminium alluyoy. Ngokuvamile, ukunemba kwayo kudlula izinga likazwelonke (njenge-GB, JIS, ASTM, njll. Indawo ephukile ingaphakathi kwe- ± 0.05mm ~ ± ama-vipe ama-0.03mm namapayipi.
Lapho ukunemba kwayo kungaphezu kokuphinda kabilini kwe-Ultra ejwayelekile ye-Ultra-ephezulu, ibizwa nge-aluminium alluminium alluwim alloy ephakeme, njengokubekezelela ukwakheka kwe- I-0.01mm yephrofayili encane (encane) noma ipayipi.

Ngo-2017, ukukhiqizwa kwezinto zokwenza izinto ze-aluminium emhlabeni kudlula ku-6000kt / a, okuthengiswayo kwe-alumininum kanye ne-aluminium alloy degresion kudlule iminyaka engama-25000kt / accounting for the I-Aluminium. I-Aluminium ekhishwe ama-Medium aphakathi kwa-90%, kwawo lapho amaphrofayili ajwayelekile kanye namabha amaphrofayili amancane naphakathi nama-professiles afinyelela ngaphezulu kwebha, amaphrofayili akhethekile aphakathi nendawo kanye nemigoqo ekhethekile eyenziwe kuphela 15%. Amapayipi agcina cishe ama-8% e-aluminium alloy ekhishwe kuyo, ngenkathi ipayipi elibunjiwe ne-akhawunti ekhethekile yepayipi ekhethekile ngamaphesenti angama-20 kuphela wepayipi. Kungabonakala kulokhu okungenhla okukhiqizwayo okukhulu kakhulu kanye nokuthengiswa kwe-aluminium kanye ne-aluminium alloy dextlesions kanye nokusetshenziswa kabanzi kumaphrofayili wokwakha amanani amancane naphakathi nendawo nemigoqo kanye namabha amapayipi. Kanye namaphrofayili akhethekile, imigoqo namapayipi kuphela asebeni cishe ngo-15%, izici eziyinhloko zemikhiqizo enjalo yilezi: ngemisebenzi ekhethekile noma ukusebenza; Enikezelwe kwinhloso ethile; Ukuba nosayizi omkhulu noma omncane wokucacisa; Ngokunemba okuphezulu kakhulu noma izidingo zangaphandle. Ngakho-ke, izinhlobonhlobo ziningi futhi i-batch incane, isidingo sokwandisa izinqubo ezikhethekile noma sengeze eminye imishini namathuluzi akhethekile, ukukhiqizwa kunzima futhi izindleko zokukhiqiza zikhuphukile futhi inani elingeziwe liyanda.
Ngenqubekela phambili yesayensi nobuchwepheshe kanye nokwenza ngcono okuqhubekayo kwamazinga okuphila kwabantu, kufakwe izidingo eziphakeme ngokuphuma, ikhwalithi nezinhlobonhlobo ze-aluminium nemikhiqizo yokukhishwa kwe-aluminium, ikakhulukazi eminyakeni eyi-PROCK Ukhuthaze ukuthuthukiswa kwamaphrofayili akhethekile namapayipi anezimpawu ezenzelwe wena kanye nokusetshenziswa okuthile.
Amaphrofayili we-Ultra-enengqondo asetshenziswa kabanzi kumathuluzi we-elekthronikhi, ezokuxhumana, ezempi kanye nezinto zokusebenza zezokuxhumana, imishini yokunemba, imishini yokunemba, imikhumbi yenuzi, imboni yezimoto kanye neminye imikhakha yodonga oluncane, oluncane, usayizi wesigaba izingxenye eziqondile. Imvamisa izidingo zokubekezelelana ziqinile, ngokwesibonelo, ukubekezelelana kukasayizi weSigaba kungaphansi kwe- ± 0.10mm, ukubekezelelana kodonga kungaphansi kwe- ± 0.05mm. Ngaphezu kwalokho, iflethi, ukusonteka nolunye uhlobo nokubekezelelana kwezikhundla zemikhiqizo eyengeziwe nakho kuyaqisa. Ngaphezu kwalokho, kwinqubo yokukhishwa kwe-Ultra encane ye-aluminium alloy amaphrofayili, imishini, isikhunta, inqubo yitidzethi eqinile. Ngenxa yokuthuthuka okusheshayo kwemboni yanamuhla, ukusika okufundwayo kwezokuvikela kanye nocwaningo lwesayensi kanye nezinye izinto zokwenza ngcono okwenziwe ngezifiso, inombolo, izinhlobonhlobo zamaphrofayili amancane we-Ultra-anembayo aya ngokuya ephakeme, yize eminyakeni yamuva, ithuthukise futhi yakhiqiza futhi ikhiqize iningi lamaphrofayili amancane aphezulu we-aluminium alloy aphezulu, kepha namanje akwazi ukufeza izidingo zemakethe, ikakhulukazi, kusekhona igebe elikhulu phakathi kobuchwepheshe bamakhaya kanye nemishini yokukhiqiza Amaphrofayili amancane we-aluminium alluminil alluy alluy kanye nezinga eliphakeme lamazwe omhlaba, elingakwazi ukuhlangabezana nezidingo zemakethe ezifuywayo nezangaphandle futhi kufanele zibanjwe.
