1 Ukubuka konke
Inqubo yokukhiqiza yephrofayili yokufaka i-thermal incuration iyinkimbinkimbi, futhi inqubo yokulahla kanye ne-laming kuphuze kakhulu. Imikhiqizo eqediwe egeleza kule nqubo iphothulwa ngomsebenzi onzima wabasebenzi abaningi benqubo yangaphambili. Lapho imikhiqizo yokudoti ivele kwinqubo ye-composite striping, izokwazi uma ibangela ukulahleka okungathi sína kwezomnotho, kuzoholela ekulahlekelweni yimiphumela eminingi yezabasebenzi edlule, okuholela ekungcoleni okukhulu.
Ngesikhathi sokukhiqizwa kwamaphrofayili okufaka umhlangano wokufaka okushisayo, amaphrofayli avame ukubanjwa ngenxa yezici ezahlukahlukene. Imbangela eyinhloko ye-scrap kule nqubo ukuqhekeka kwama-notches wokushisa ama-strip. Kunezizathu eziningi zokuqhekeka kwe-notch eshisa ukushisa, lapha ikakhulukazi sigxila kwinqubo yokuthola izizathu zezinkinga ezifana nenqubo yokukhishwa kwe Amaphrofayili okushisa okushisa we-aluminium wolloy ngesikhathi sokuhlwitha nokulahla, futhi axazulule le nkinga ngokwenza ngcono isikhunta nezinye izindlela.
2 phenomena
Ngesikhathi senqubo yokukhiqiza eyinhlanganisela yamaphrofayili okushisa okushisa okufudumele, ukuqhekeka kwe-batch kwama-notche afudumele ngokuzumayo. Ngemuva kokubheka, into ephukile inephethini ethile. Konke kuqhekeka ekugcineni kwemodeli ethile, futhi ubude be-crack bufana. Kungaphakathi kwebanga elithile (20- 40cm kusukela ekugcineni), futhi izobuyela kokujwayelekile ngemuva kwesikhathi sokuqhekeka. Izithombe ngemuva kokuqhekeka zikhonjiswe kuMfanekiso 1 naku-PORD 2.
3 Ukuthola inkinga
1) Okokuqala, hlukanisa amaphrofayili anenkinga bese uwagcina ndawonye, hlola into ephukile ngakunye, bese uthola okujwayelekile nokwehluka kokuqhekeka. Ngemuva kokulandela umkhondo ophindaphindwayo, into ephukile inephethini ethile. Konke kuqhekeka ekugcineni kwemodeli eyodwa. Ukwakheka kwemodeli ephukile kuyisiqephu esivamile sezinto ezibonakalayo ngaphandle komgodi, futhi ubude bokuqhekeka bungaphakathi kwebanga elithile. Ngaphakathi (20-40cm kusukela ekugcineni), izobuyela kokujwayelekile ngemuva kokuqhekeka isikhashana.
2) Kusuka ekhadini lokulandela umkhondo lokukhiqiza la maphrofayli, singathola inombolo yokubumba esetshenziselwe ukukhiqizwa kwalolu hlobo, ngesikhathi sokukhiqiza, usayizi wejometri wale modeli uyahlolwa, kanye nosayizi wejometri wokushisa I-Insulation strip, izakhiwo zemishini zephrofayili kanye nobulukhuni bendawo konke kungamahlu anengqondo.
3) Ngesikhathi senqubo yokukhiqiza eyinhlanganisela, amapharamitha ahlanganisiwe kanye nemisebenzi yokukhiqiza yalandelelwa. Kwakungekho zinto ezesabekayo, kepha kwakukhona imifantu lapho kukhiqizwa khona iqembu lamaphrofayili.
4) Ngemuva kokubheka ukwaphuka lapho kufa khona, ezinye izakhiwo ezinqabile zatholakala. Uma kucatshangelwa ukuthi imbangela yalesi simo kufanele ibangelwa iziphazamiso zokukhishwa ezibangelwa inqubo yokukhishwa.
5) Kulesi simo esingenhla, kungabonakala ukuthi imbangela yokuqhekeka akuyona ubunzima bephrofayili nenqubo eyinhlanganisela, kepha ekuqaleni iyazimisela ukubangelwa yizici zokukhishwa. Ukuze kwenziwe ukuqinisekisa imbangela yenkinga, kwaqhutshwa izivivinyo ezilandelayo.
6) Sebenzisa isethi efanayo yokubumba ukwenza izivivinyo ngemishini ehlukene ye-tonnage ngejubane elihlukile lokukhishwa. Sebenzisa umshini wamathani amathani angama-600 kanye nomshini wamathoni angama-800 ukwenza isivivinyo ngokulandelana. Maka ikhanda lezinto ezibonakalayo nomsila wezinto ezibonakalayo ngokwahlukana bese uwafaka kumabhasikidi. Ubulukhuni ngemuva kokuguga ngo-10-12hw. Indlela ye-Alkaline Water Corrosion yayisetshenziselwa ukuhlola iphrofayili ekhanda nomsila wezinto ezibonakalayo. Kwatholakala ukuthi umsila wezinto ezibonakalayo wawunciphise umsila kanye ne-stratification denomena. Imbangela yokuqhekeka yayinqunywe ukubangelwa yi-shrink umsila kanye ne-stratification. Izithombe ngemuva kwe-Alkali Etching zikhonjiswe kwizibalo 2 no-3. Ukuhlolwa okuhlanganisiwe kwenziwa kuleli qembu lamaphrofayili ukubheka into ephukile. Imininingwane yokuhlola ikhonjiswa kuThebula 1.
Imidwebo 2 no-3
Ithebula 1
7) kusuka kwimininingwane etafuleni elingenhla, kungabonakala ukuthi akukho okuqhekekile ekhanda lokuqukethwe, futhi ingxenye yokuqhekeka emsileni wezinto ezibonakalayo inkulu kakhulu. Imbangela yokuqhekeka kuncane ukukwenza ngosayizi womshini kanye nejubane lomshini. Isilinganiso sokuqhekeka kwezinto zomsila ezinkulu kunazo zonke, ezihlobene ngokuqondile nobude bendawo yomsila. Ngemuva kwengxenye yokuqhekeka ifakwe emanzini anama-alkali futhi kwahlolwa, kuzovela umsila wokuncipha kanye nokuqina. Lapho izingxenye zomsila nokuhlanza izingxenye zinqunywe, ngeke kube khona ukuqhekeka.
Izindlela ezi-4 zokuxazulula izinkinga nezindlela zokuvimbela
1) Ukuze unciphise ukuqhekeka kwe-notch okubangelwa yilesi sizathu, ukuthuthukisa isivuno, futhi kunciphise imfucuza, lezi zinyathelo ezilandelayo zithathwa ngokulawulwa kokukhiqiza. Lesi sixazululo silungele amanye amamodeli afanayo afana nalemodeli lapho ukukhishwa kufa khona ifulethi lifa. Umsila we-Shrink umsila kanye ne-stratification phenomena ekhiqizwa ngesikhathi sokukhiqizwa kwe-detlesion kuzodala izinkinga zekhwalithi njengokuqhekeka kwezimpawu zokugcina ngesikhathi sokuhlanganisa.
2) Lapho wamukela isikhunta, lawula ngokuqinile usayizi we-notch; Sebenzisa ucezu olulodwa lwezinto ezibonakalayo ukwenza isikhunta esisezingeni eliphansi, engeza amakamelo okubuyisa kabili kwisikhunta, noma uvule isikhunta sokuqhekeka esingamanga ukuze sinciphise umthelela wekhwalithi womsila osusiwe.
3) Ngesikhathi sokukhiqizwa kwe-Extrolsion, ingaphezulu lenduku ye-aluminium kumele ihlanzeke futhi ingenalo uthuli, uwoyela kanye nokunye ukungcoliswa. Inqubo yokukhishwa kwe-Extrusion kufanele yamukele kancane kancane imodi yokukhishwa ekhishwa. Lokhu kunganciphisa ijubane ijubane lokukhipha ekugcineni kokukhishwa futhi kunciphise ukuncipha komsila kanye nokuqina.
4) Ukushisa okuphansi nokukhishwa kwesivinini esikhulu kusetshenziswa ngesikhathi sokukhiqizwa kwe-dexcusion, futhi izinga lokushisa le-aluminium rod emshinini lilawulwa phakathi kuka-460-480 ℃. Ukushisa okubumba kulawulwa ngo-470 ℃ ± 10 ℃, izinga lokushisa le-Extresion lilawulwa cishe ngo-420 ℃, kanti izinga lokushisa le-Extresion atholwa lilawulwa phakathi kuka-490-525 ℃. Ngemuva kokukhishwa, i-fan ivuliwe ukuze ipholile. Ubude obusalayo kufanele bukhuphuke ngaphezu kwe-5mm kunokujwayelekile.
5) Lapho ukhiqiza lolu hlobo lwephrofayili, kungcono ukusebenzisa umshini omkhulu ukukhulisa amandla okukhishwa, uthuthukise izinga le-metal fusion, futhi uqinisekise ubungako bezinto ezibonakalayo.
6) Ngesikhathi sokukhiqizwa kwe-Extrusion, kufanele kulungiselelwe ibhakede lama-Alkali Amanzi kufanele lilungiselelwe kusengaphambili. U-opharetha uzokubona umsila wezinto ezibonakalayo ukuze ahlole ubude be-shrink umsila kanye ne-stratification. Imivimbo emnyama e-Alkali-Etched Surched ikhombisa ukuthi ukuncipha komsila nokuhlaziywa kwenzeke. Ngemuva kokuqhubeka nokubona, kuze kube yilapho isigaba sesiphambano sikhanya futhi asinamivimbo emnyama, hlola izinduku ze-aluminium ezi-3-5 ukuze ubone izinguquko zobude ngemuva kokuncipha komsila kanye nokuqina. Ukuze ugweme ukuncipha komsila kanye nokuhlukaniswa kusuka ekulethwe kwimikhiqizo yephrofayili, kufakwa i-20cm ngokuya ngawo omubi kunabo bonke, kunqume ubude bemsila wesethi yokubumba, baqala ukubhekana nomkhiqizo osuqediwe. Ngesikhathi sokusebenza, ikhanda nomsila wezinto ezibonakalayo kungashukunyiswa futhi kwabonakale kalula, kepha iziphambeko akufanele zilethwe kumkhiqizo wephrofayili. Egadiwe futhi ihlolwe ukuhlolwa kwekhwalithi yomshini. Uma ubude bomsila we-shrink kanye ne-stratation buthinta isivuno, susa isikhunta ngesikhathi bese unquma isikhunta kuze kube yilapho ukukhiqizwa okujwayelekile kungaqala.
Okufingqiwe
1) Amabheji amaningana amaphrofayili okushisa afaka ukushisa akhiqizwa esebenzisa izindlela ezingenhla ahlolwe futhi akukho okuqhekeka kwe-notch efanayo. Amanani angokomfanekiso we-Shear wamaphrofayili wonke afinyelela kwizidingo ze-GB / T5237.6-2017 "Aluminium Alloy wokwakha amaphrofayli Amaphrofayli No. 6 Ingxenye".
2) Ukuze uvimbele ukwenzeka kwale nkinga, kwasungulwa uhlelo lwansuku zonke lokuhlola ukubhekana nale nkinga ngokuhamba kwesikhathi futhi lwenza ukulungisa ukuvimba amaphrofayili ayingozi ekugelezeni inqubo eyinhlanganisela futhi anciphise imfucuza inqubo yokukhiqiza.
3) Ngaphezu kokugwema ukuqhekeka okubangelwa iziphambeko zokukhishwa, ukuncipha komsila kanye nokuqina, ngaso sonke isikhathi kufanele sinake into eqhekekile ebangelwa yizinto ezinjenge-geometry ye-notch, ubulukhuni bemishini yezinto ezibonakalayo kanye namapharamitha enqubo yenqubo eyinhlanganisela.
