Iiprofayili zealuminium ezifunyenwe yi-extrusion

Zininzi iinkqubo zeshishini zokwenza iinxalenye, enye yazo extrusion. Kule meko, ayibizi kwaye iyasebenza kakhulu kwizinto ezininzi ezithambileyo okanye ezilahliweyo ezinokubunjwa ngokuchanekileyo nangokukhawuleza yile nkqubo.

Jonga ziphene yokubumba, kuba ayifani kodwa amaxesha amaninzi iyabhideka.

Ukukhupha

Inkqubo yeskripthi

La extrusion Inokubandakanya ukusebenzisa umlomo kunye nomphandle onemilo ethile kwaye ke ngoko zenza izinto ezinomnqamlezo othile. Ukuze usebenze, njengoko unokuqonda, imathiriyeli kufuneka ibe ye-ductile kwaye ibhetyebhetye ngokwaneleyo ukuba idlule kuloo extruder.

Ngokwenza ubume ngokuqengqeleka, unokuthintela ezinye iinkqubo ezisebenzisa ukungunda, ucinezelo, okanye ukucheba:

  • Ngokungasebenzisi ukungunda, kuyakhawuleza ukwenza isiqwenga. Ukongeza, ezinye izinto zinamathele kakhulu okanye zinempawu ezingahambelani kakuhle nokubumba.
  • Abadingi ucinezelo, kuba banako ukuthintela izinto ekubumbaneni xa oku kunokuchaphazela iipropathi zabo.
  • Ukucheba okanye ukubetha indawo ukuyenza kuyathintelwa, okuluncedo kwizixhobo ezomeleleyo okanye ezifuna iimilo ezintsonkothileyo ezingenakufezekiswa ngenye indlela.
  • Imilo yokugqibela ikumgangatho ophezulu kwaye umphezulu wokugqiba ulunge kakhulu.

Namhlanje, i-extrusion inokusetyenziselwa ubuninzi be izinto, ezinjengeepolymers (iiplastiki), isinyithi kunye neealloys zazo, iiseramikhi, ikhonkrithi, kunye nezinye ezininzi. Umzekelo, kwishishini lokutya, ngaphandle kokuya phambili, lisetyenziselwa iinkqubo ezininzi. Eyona nto iqhelekileyo yipasta, enokuthi ikhuphe intlama ukuze yenze iimilo ezahlukeneyo.

Okwangoku, ngetekhnoloji entsha ye 3D yoshicilelo, i-extrusion ifikelele kwinqanaba elitsha. Ngamathuba amaninzi, kunye nokunciphisa kakhulu iindleko zemveliso yamalungu awayefudula ebiza okanye engenakwenzeka.

Extrusion yokubumba

extrusion yokubumba

El extrusion yokubumba inokwenziwa ngokweemodeli ezahlukeneyo okanye iintlobo. Isitshixo sisendleleni apho izinto ezisetyenzisiweyo zihamba ngokufa okanye ukubekwa kwindawo ebekwe entloko kumatshini wokukhuphela. I-extruder ithe inzima kunezinto eziphathwayo kwaye inemilo esele ichaziwe ekufuneka ifezekisiwe (isetyhula, inkwenkwezi, iflethi, njl.

Oko kwathiwa, zininzi iindlela zokwenza extrusion yokubumba:

  • Kuyabanda: Izinto ekubhekiswa kuzo zithambile, zibhetyebhetye kwaye zine-ductile ngokwaneleyo ukuba kungafuneki zifudunyezwe. Umzekelo, ipasta, iiplastiki ezithambileyo okanye irubber, ikhonkrithi, njl. Kweminye imathiriyeli kunganyanzeleka ukuba kufakwe iqondo elithile lobushushu ukuthambisa umbandela, kodwa ngaphandle kokufikelela kumaqondo obushushu aphezulu anokuwonakalisa okanye awenze abe ngumphunga. Umzekelo, itshokholethi.
  • Kushushu: Banokuhamba ukusuka kuma-400 ukuya kumawaka alishumi eedigri, kuxhomekeke kwinto ephathwayo. La matyala ayasebenza kwiplastikhi enzima, isinyithi (titanium, igolide, i-aluminium, i-magnesium, i-aluminium, ubhedu, isinyithi, ii-alloys, ...), njl.
  • Ukungena phakathi ngokuqhubekayoUmzekelo, kwimeko yesinyithi, ukuba yenziwa ngokuqhubekayo, amashiti amade okanye imisonto inokufunyanwa ukwenza iingcingo ezinde, abaqhubi, njl. Ngeplastiki kwiifom eqhubekayo zinokubakho. Endaweni yoko, ezinye iziqwenga zifuna ukwenziwa ngamaxesha athile. Ngokubanzi, i-blade ebekwe ngasemva kwe-extruder isika lonke ixesha elithile oko kuphuma kwi-extruder. Ngale ndlela ufumana iinxalenye ezincinci. Umzekelo, kwimeko yepasta, ungasika "ityhubhu" eqhubekayo ephuma ukudala imacaroni yeesentimitha ezimbalwa.
  • Ukonakala: ukubeka unobumba kwakhona njengomzekelo, kunokwenzeka ukuba wenze i-spirals nge-extruder. Kule meko, into edla ngokwenziwa kukujikelezisa ngomatshini indawo ephuma kwi-extruder okanye ukujikeleza i-extruder uqobo. Ngamanye amaxesha, ungasweleka enemingxunya emininzi yokwenza i-braiding, njl.

Kananjalo indlela ulwelo okanye izinto ezityhalelwa ngayo kwi-extruder iyahluka kwaye ikhokelela kwiziphumo ezahlukeneyo iintlobo ze-extrusion. Njenge-extrusion ethe ngqo nengathanga ngqo, kuxhomekeka kwindlela izinto ezityhalelwa ngayo ekufeni okanye kwi-extruder.

Ukukhutshwa kweplastiki

La Ukukhutshwa kweeplastikhi Isetyenziswa ngokubanzi kumzi mveliso, ngenxa yezicelo ezininzi zeplastiki. Kule meko, isondli iya kubonelela ngeplastikhi eshushu ukuze ikwazi ukuhamba ngesikere esiza kutyhala i-resin ngamandla ukuze idlule kwidiski okanye umlomo ngemilo oyifunayo. Inokuba ngohlobo lweshiti, ityhubhu, njl.

Xa uphuma kwi-extruder, iqhekeza liyabanda. Ngokungafaniyo nezinye iziqwenga, ezinokupholisa kubushushu begumbi okanye ngeendlela ezisebenzayo, ngomoya, ngamanzi, njl. extruder (pultrusion) ukuze ipholile kwaye igcine imo efanayo. Kwezinye iimeko, idlula kwi-rollers yokupholisa (i-calender) xa ubume bukhanya.

Kwimizi-mveliso, xa i-extruder ivalela okanye xa icandelo lingalinganiyo ngenxa yayo nayiphi na ingxaki yoomatshini, idla ngokutyiswa ibuyiselwe kwi hopper kunye nezinto ezibonakalayo ukuze ungamoshi kwaye ngenxa yoko uphinde uphinde udlule kwi-extruder.

Izinto zeplastiki ezinokukhutshelwa ngaphandle ukusuka kwiiplastiki ezinje I-PVC, irubbers, njl.

Ukutsalwa kwentsimbi

Los isinyithi sinokukhutshelwa ngaphandle njengeplastiki, ekuphela kwento ekufuneka ifudunyezwe kumaqondo obushushu aphezulu kakhulu ukuze ubanyange. Kule meko, kuxhomekeke kuhlobo lwesinyithi esulungekileyo okanye ingxubevange, ukugqitywa kunokuba ngcono okanye kubi. Kumgangatho womphezulu, into ye-RMS (Ingcambu yeSiseko seSikwere) ihlala isetyenziswa, Oko kukuthi, amaxabiso kwii-microinches ezibonisa ukuba umphezulu ugudile okanye uyarhabaxa xa ujongwa ngemicroscope, kuba ayixatyiswanga kakuhle ngamehlo.

umlomo we-extrusion

Umzekelo, i-aluminium-magnesium alloy ihlala ine I-RMS Ii-microinches ezingama-30, okanye yintoni enye, 0.75 microns. Ngamanye amagama, uburhabaxa bomphezulu wayo bunokufikelela kule milinganiselo. Kwelinye icala, izinto ezinje nge-titanium okanye intsimbi zine-RMS yodidi oluthe kratya, nge-125 microinchs okanye 3 microns ...

Phakathi izinyithi ezithandwa kakhulu ezinokukhutshelwa ngaphandle zezi:

  • IAluminiyam: Ngaba extruded kushushu okanye kubanda. Xa kushushu, kuhlala ku-300-600ºC. Olu hlobo lwe-extrusion lusetyenziselwa ukwenza ucango lwealuminium kunye neefestile zeefestile, imivalo yezicelo ezininzi, izixhobo zokuhambisa izixhobo zombane kunye noomatshini, njl.
  • ICopper: Yenziwa kumaqondo obushushu ashushu, phakathi kwe-600-1000ºC, kwaye ngale nto, iimveliso ezithandwayo ezinje ngeengcingo zokuqhuba iintambo, imibhobho yokufaka imibhobho yamanzi, ii-electrode zentsimbi, njl.
  • wemagniziyaminokukhutshwa yodwa okanye ingxubevange ene-aluminium. Xa yenziwe, kusetyenziswa kuphela amaqondo obushushu angama-300-600ºC, oko kukuthi, kuyafana nakwimeko yealuminium. Kule meko, ii-alloys zilula kakhulu kwaye zisetyenziselwa izinto zokugcina izixhobo, kunye neenxalenye zeenqwelomoya, iinxalenye zeshishini lenyukliya, njl.
  • Acero: yenye yezona zinto zisetyenziswayo namhlanje. Isetyenziselwa ukwenza izinto ezinyukayo, imiqadi, iingcingo, njl. Ukukhutshwa kulo mzekelo kwenziwa kubushushu obuphakathi kwe-1000 ukuya kwi-1300 ° C, kwaye iikristali zingasetyenziswa njengesithambisi se-extruder kunye ne-phosphates.
  • titanium: yenye yesinyithi exabiseke kakhulu ngokusebenza kwayo kunye nokukhanya. Ihlala isetyenziselwa ukuhamba ngenqwelomoya, iinxalenye zonyango, njl. Ubushushu obuyimfuneko kwezi meko buphakathi kwama-600 ukuya kuma-1000ºC, kuxhomekeke kuhlobo lobume nobungakanani.
  • Ilothe kunye netoti: zombini enye ithambile kwaye iyabumba, yiyo loo nto amaqondo obushushu esiba sezantsi, ajikeleze ama-200-300ºC. Zisetyenziselwa ukwenza i-linings okanye i-coilings, iingcingo ze-welding, njl.

Banokukhutshelwa ngaphandle ezinye izinyithi ezininzi, ezinje ngeealloys ezingasentla, i-iron, i-zinc, njl.
