Ukubaluleka kunye noyilo lwe-iron yentsimbi

1. Iindawo zokuyila zentamo yentsimbi yentsimbi imi ngolu hlobo lulandelayo:

Ubungakanani bokuzimisela: Ububanzi bentamo evuthayo buyi-0.3-0.8 AMANQAKU OBUGQIBELELEYO IXESHA lendawo yendawo eshushu. Ububanzi bendawo eshushu yendawo yokuphosa bukhulu, ngexabiso eliphantsi kwe-0.3; Ububanzi besangqa sendawo eshushu sincinci, ngexabiso elixhonywe kwi-0.8. Ubude: Ngokwesiqhelo phakathi kwe-20-50mm. Ngeenxalenye ezincinci zentsimbi, ubude bendlela yokukhula inokuthathwa njengomda ophantsi; Iindawo ezinkulu zentsimbi ziphantsi komda ophezulu. Imilo eqhelekileyo yokuyila koyilo ibandakanya i-cylindrical, i-trapezoidal, njl. Intamo ye-cylindrical isebenza ngokulula kwaye ilungele iimeko ezininzi; Intamo yokunyuka kwe-trapezoidal iluncedo ekuqinisekiseni i-shrinkige yembuyekezo kwaye isetyenziswe ngokubanzi kwiziphumo ezineemfuno eziphezulu zokugcina imbuyekezo.

Isikhundla sokunyulwa kwentamo esivuthayo kufuneka sibekwe kwindawo eshushu yokuphosa, ukuze i-nyibilingle kwinkcitho inokuhamba ngokuthembekileyo kwi-cunfered eshushu, kwaye ifumane i-spinkini efanelekileyo. Zama ukunqanda ukuyibeka kwindawo yoxinzelelo lwendawo yokuphosa ukuthintela uxinzelelo olubangelwe yimfesane yokuqina, enokwenza umkhwa wokuphosa. Ubungakanani buzimisele ngokubhekisele kubungakanani bokuphosa, ubunzulu bobume, kunye nokusasazwa kwamabala ashushu. Iincwadana ezincinci nezilula zinokufuna kuphela intamo yentamo, ngelixa iimbambano ezinkulu nezintsonkothileyo zinokufuna ukubakho kweenjongo ezininzi ukuqinisekisa ukuba i-shrinkige eyoneleyo kwi-shrinkid eyaneleyo. Unxibelelwano phakathi kokuphakama kunye nokuphosa kufanele ukuba kube nenguqu egudileyo, ukunqanda iikona ezichanekileyo okanye ezibukhali ukunciphisa ukunganyangeki kwentsimbi yentsimbi. Unxibelelwano phakathi kwentamo ekhulayo kunye nokuphosa kufuneka kuqinile ukukhusela ukophula ngenxa yefuthe lentsimbi enyibilikayo ngexesha lenkqubo yokuphosa. Kwangelo xesha, imilo kunye nobungakanani bonxibelelwano kufuneka zenziwe ngokungqinayo ukuthintela ukwenziwa kobushushu obugqithisileyo ekuphoseni, nto leyo inokubangela iziphene.

I-2. Yiloyike uhlalutyo lwetyala lentsimbi yentsimbi

Uninzi lwe-alloys lobongathelayo kunye nokuziphatha okuqiqa ngexesha lenkqubo yokupholisa ukusuka kulwelo ukuya kwiqondo lokushisa. Kukho amanqanaba amabini ahlukeneyo okwenzakala. Okokuqala, xa amaqondo obushushu e-Alfy epholile kumgca we-rileus, oku kubizwa ngokuba njenge-strinkid yolwelo okanye i-shrinkad eguqulweyo. Okwesibini, xa i-alloy ipholile ukusuka kulwelo ukuba iqinile, idla ngokubizwa ngokuba yi-shrintage. Kwelinye icala, igrafu yaphosa iintsimbi zentsimbi (kubandakanya i-iron engwevu, i-iron yentsimbi, kunye ne-Iron yentsimbi) ehamba ne-iron engaqhelekanga xa iqinile ngexesha lokupholisa nokwandisa isinyithi. Olu lwandiso luhlala lubonakaliswa kukwakhiwa kwezigaba zegrafire eziphantsi, ukoyisa kwaye kungaphezulu kwe-shrinkad ehambelana nokuphuculwa okupholiselweyo kunye nokuqiniswa kwe-iusten. Ukuza kuthi ga ngoku, eyona nkalo ibaluleke kakhulu yokuyila umphezulu kunye neenkqubo ze-Gating ze-Irsing yimfuneko yokugcina uxinzelelo olululo lwenkqubo yokuqiniswa kuyo yonke inkqubo yokuqiniswa kuyo yonke inkqubo yokuqiniswa kwayo kuyo yonke inkqubo yokuqiniswa. Ekuqaleni, uxinzelelo lwe-atmospheric kufuneka luvunyelwe ukuba lusebenze kwi-windows kwi-loliwe, kwaye ukuze le nto lenzeke, ukuphakama kufuneka (icinezelwe). Nje ukuba amandla aqalise, inkqubo eyoyikekayo eyenziwe ngononophelo ilawula uxinzelelo lokwandiswa kwaye iqinisekisa ukunyibilikiswa ngokuzenzekelayo kokuphoswa kwenkqubo enokuqiniswayo. Oku kwahlulahlula kwintsimbi, i-aluminium, ubhedu, njl njl.

3. Uxinzelelo lolawulo

Intamo ekhulayo inokuba yeyona nxalenye ibalulekileyo ekuphumeleleni uyilo lwenkqubo, njengoko ithatha ubungakanani bobukhulu boxinzelelo lwentsalela kulwelo. Umphezulu woqhakamshelwano wentamo ovuthayo kufuneka ibe nkulu ngokwaneleyo ukuba idlulisele inyibilikisi ukusuka ekukhuleni kwexesha elide. Ukuba kukho imfuneko, ingcinezelo egqithisileyo kwi-mobnity ye-mold kufuneka ikhutshwe, kodwa kufanelekile ukugcina uxinzelelo olufanelekileyo lolwelo olusekupheleni kokukhuselwa ekuphoseni. Intamo ekhulayo inokuthathwa njenge "Valveve Erverve" kwiinqanawa zoxinzelelo, kwaye uyilo lwayo kufuneka luqinisekise ukuba uxinzelelo ngaphakathi kwestoking lugcinwa kwinqanaba elilawulwayo. Izinto ezibunjiweyo, okanye ngokuthe ngqo, i-sand yesanti enokumelana noxinzelelo lokwandiswa ngaphandle kokwanda, idla ngokumisela inqanaba lokulawulwa kwendawo. Ukuba izinto ezibunjiweyo zibuthathaka, njengokusebenzisa i-Clay Sulds, intamo ekhulayo kufuneka yenzelwe ukukhupha uxinzelelo olukhoyo ukunqanda ukwanda kokubumba. Oku kufezekiswa ngokuyila intamo ekhulayo ukuqinisa kwinqanaba lokugqibela, kuvumela uxinzelelo oluthile lokukhutshwa kwintamo ende. Ngokusebenzisa izinto ezinamandla nezinzima kakhulu (ezinjengeenkqubo ze-resin), intamo ekhulayo inokuba incinci, ivumele iqinile kwangethuba kwisigaba sokwandiswa kwaye sigcine uxinzelelo lwamanzi oluphezulu. Nangona kunjalo, intamo encinci kakhulu inokukhokelela kuxinzelelo olugqithisileyo olugqithisileyo ngaphakathi kokuphosa, kukhokelela ekubeni nenkalipho enxulumene nokwanda kokubumba. Intshukumo enkulu kakhulu iphakama ikhokelela ekuphulukaneni noxinzelelo olufanelekileyo kulwelo ngaphambi kokuba iqinisekiswe, kukhokelela kwi-shrinkage kwaye ikhutshiwe kwi-shrinkage kunye ne-shrinkige ukusuka kwi-shrinkiage. Ubungakanani bentamo evuthayo kwimithetho yoyilo ihlala isekwe kwi-Peometric Moge (MC) yokuphosa. Ixabiso eliqhelekileyo lokuphoswa kwentsimbi eveliswe kwi-floy sand iphakathi kwe-0.6 (MC) kunye ne-0.9 (MC). Ixabiso elichanekileyo lixhomekeke kubunzima bezinto zentlabathi, ukwakhiwa kweekhemikhali kunye nenqanaba lensimbi yentsimbi, kunye nenqanaba lokupholisa lokuphola. Ukuba ukuphakama kusondela kufutshane nokuphosa, isiphumo sokufudumeza kwisanti phakathi kokuphosa kunye nentamo evuthayo kuya kunciphisa i-jometric yoqhakamshelwano ngelixa igcina i-mogulsus elinganayo. Ukuba intamo imfutshane ngokwaneleyo ukuba ilingane okanye ingaphantsi kosayino oluncinci loqhakamshelwano, imometric imodyuli inokukhuselwa ngokukhuselekileyo ngamaxesha amdaka. Oku kubonisa ukuncitshiswa kwe-65% kwindawo yoqhakamshelwano.

ukuqukumbela

I-Strinkied ephumeleleyo ye-intsimbi ye-intsimbi ibandakanya ukugcina nokulawula uxinzelelo olufanelekileyo lwensimbi yentsimbi yonke. Ukuyila ngokuchanekileyo inkqubo yokuphakamisa kunye nokugalela, kunye nokulawula ixesha lokunyanga kunye nokugalela ixesha kakuhle, kubaluleke kakhulu ekuveliseni iinxalenye ze-iron ngaphandle kwe-rintage.
