Isingeniso Enqubeni Yokuphonsa Yeziphepheli ezinkulu ze-Alloy Copper

Indlela yokumodela

Ngenxa yesimo esiyinkimbinkimbi se- ukuhambisa umkhumbi izindwani nosayizi omkhulu wohlaka lwendiza enkulu kakhulu, ubuchwepheshe bokubumba jikelele bubaluleke kakhulu. Ikhwalithi yokubumba ayanele, okungadala ukuthi ukusakaza kwehluleke ngosayizi futhi kubangele ukuthi ukulahlwa kusulwe. Ngakho-ke, inqubo yokumodela yondiza ibaluleke kakhulu.

Njengamanje, ukwakheka komphepheli ngokuvamile kusebenzisa igeji ekhombisa ukuphakama yedijithali, ithempulethi enqamulelayo, ithempulethi yolayini we-engeli kanye nokumodela okwenziwa ngesandla. Imininingwane yesihlabathi ifakwe kwikhompyutha ye-CAD. Le mininingwane kumele icabangele ukusonteka kokuphonsa, izici zokuncipha kwe-alloy, kanye nesabelo esifanele semishini. Ngemuva kokuthi isikhunta sesihlabathi senziwe, ithempulethi yokuhlola efana nethempulethi engxenyeni yesiphambano kanye nethempulethi yomugqa we-engeli isetshenziselwa ukubuyekeza usayizi womumo weqabunga ukuqinisekisa ukuthi idatha ihlangabezana nezidingo.

Ukunqunywa kokuncipha

I-paddle blade ibanzi futhi ubukhulu be-blade busatshalaliswa ngokungalingani. Ubukhulu obukhulu besithende se-blade ngu-336mm kanti ithiphu le-blade lingu-22mm kuphela. Igebe likhulu kangangokuba izinga lokushisa lokusakaza nejubane lokupholisa lihlukile kulo lonke ithuba lokusakaza. Kodwa-ke, izici nemithetho ethinta ukuguqulwa ayikaqondakali ngokuphelele. Unqenqema oluholayo luba ngaphansi phansi, futhi umphetho uguqulelwa phezulu, i-blade ikhubazekile, futhi iphimbo liba lincane. Ngakho-ke, kubekiwe ngokomthetho ukuthi izinga lokuncipha (0.2 ~ 0.4) R iphimbo lingu-1.0%, izinga lokuncipha lika (0.5 ~ 0.7) R lingu-2.0%, kanti izinga lokuncipha lika (0.8 ~ 1.0) R lingu-3.0% ; umugqa jikelele Isilinganiso sokuncipha sithathwa njengo-1.5%.

Ukuzimisela kwevolumu yemishini

Ukuze kuncishiswe ukukhubazeka okungaphezulu kokuphonswa futhi kutholakale ukusakazwa ngobukhulu obufanelekile kanye nekhwalithi enhle yendawo, izidingo zokuncipha kanye nokusonteka kukodwa akukwazi ukuhlangabezana nezidingo, futhi nesibonelelo semishini kumele sengezwe ngokufanele. Isabelo semishini yensimbi sinqunywa ngokulandelayo: shiya isabelo semishini ebusweni bensimbi; shiya isabelo semishini ebusweni bensimbi; bona Umfanekiso 1 we imishini Castings isabelo se-blade back; 20mm; I-10mm ngakolunye uhlangothi lwendilinga engaphandle yehabhu, i-15mm ngakolunye uhlangothi lomgodi ongaphakathi wehabhu, ubude obungu-15mm ekugcineni okukhulu kwehabhu, kanye no-10mm ubude ekugcineni okuncane.

Isango likhonjwe

Njengoba impahla ye-propeller i-ZCuAl9Fe4Ni4Mn2 iqukethe i-Al eningi, kulula ukwenza i-slag yesibili ye-oxide ngesikhathi senqubo yokuthela. Ngakho-ke, ekwakhiweni kohlelo lokuthela, kufanele kubhekwe ukuthi ngabe uhlelo lokuthela lungaqinisekisa ukugcwaliswa okushelelayo kuketshezi lwensimbi, futhi kufanele lube nokuthelwa okunengqondo ngeSivinini, ukuvimba i-slag kanye nekhono lokususa i-slag ukuvimbela isiyaluyalu. Umjovo ongezansi uvame ukwamukelwa, futhi isilinganiso esivamile sesigaba esiphambanayo sohlelo lokuthela luqondile: ngokuvundlile: ngaphakathi = 1: (2 ~ 2.5): (10 ~ 30). Ngenxa yesisindo esikhulu esikhulu sokusakaza, kusetshenziswa abagijimi abaqondile abangu-φ60mm kanye nama-26 φ60mm. Ngaphakathi kwesango.

Ukuncipha kukaphethiloli wengxubevange yethusi cishe kungu-1.5%, ngakho-ke ukwakhiwa kweriseli nakho kubaluleke kakhulu. Ngokuvamile, ukuphakama kwendlela yokukhuphuka kuphindwe izikhathi ezingu-0.6 kuye ku-0.8 ukuphakama kwehabhu.

Ukubhaka nokupholisa

Isikhunta somiswa yisiphephetha-moya esishisayo, esinciphisa kakhulu umswakama esihlabathini sokubumba futhi sinciphise ukukhubazeka okufana ne-porosity ne-slag ene-oxidized ngenxa yomswakama owedlulele esihlabathini sokubumba. Ukomisa umfaniswano, indawo yokuphuma emoyeni ethiphu yensimbi iyavulwa endaweni ephansi kakhulu ohlangothini lwe-paddle. Isikhunta sigcinwa ku-150 ° C cishe amahora angama-24 ukuqinisekisa ukuthi izinga lokushisa komoya alikho ngaphansi kuka-40 ° C.

Ngoba i-paddle blade ine-gradient enkulu yokujiya, nakanjani izodala izikhathi ezahlukahlukene zokupholisa zezingxenye ezahlukahlukene. Ukuze kuqinisekiswe ukuthi ukusakaza kunamandla anele, ukulondolozwa kokushisa kwalokhu kuphonsa akukho ngaphansi kwe-120h ngemuva kokuthela. Lapho izinga lokushisa lehla laya ku-300 ° C, isibhakela siyenziwa. Ngokwelula isikhathi sokupholisa, ukusakaza kungakhipha ngokuphelele ukucindezela kokulingisa ukuvimbela ukusonteka kwe-blade ngenxa yesilinganiso sokushisa esikhulu.
