CNC imishini.
Isisekelo: Kungani IMagnesium, Futhi Kungani Ikhohlisa
Sisebenza ngezinto eziningi zokwakha kwa-QSY—ama-alloys asuselwa ku-nickel asuselwa ku-nickel ezindaweni ezeqisayo—kodwa i-magnesium alloy die casting ithatha niche eyingqayizivele. Isikhalazo sisobala: amandla amangalisayo-kuya-isisindo, ukumanzisa okuhle, ubuciko obuhle kakhulu. Kodwa idumela layo ‘lokuba lula’ ukulisakaza liyadukisa. Yebo, igeleza njengamanzi uma iqhathaniswa ne-aluminium, igcwalisa izingxenye ezincane kahle. Yilokho okuphambene. Okubi ukuthi i-fluidity efanayo iyenza ijwayele ukugcwala isiyaluyalu uma uhlelo lokudubula lungalungiswanga kahle, okuholela ekungeneni komoya kanye ne-porosity lapho ongakufuni khona-ezindaweni ezihlelelwe ukunemba okuphezulu imishini kamuva. Awukwazi ukufaka umshini embotsheni.
Ngikhumbula iphrojekthi yezindlu zezinzwa eminyakeni embalwa edlule. Ingxenye ibinokubekezelela okungu-0.05mm endaweni ebucayi. Sisebenzise ingxubevange ye-premium, kodwa amashothi okuqala ahlulekile ukuhlolwa. Indaba yayingekona ukuhlanzeka kwengxubevange; kwakuwukungaguquguquki kwezinga lokushisa. Ingxenye eyodwa yefa ibisebenza ngokupholile ngo-30°C kunenye, ibangele ukuqina okungalingani kanye ne-warpage ebulale ukunemba. Kudingeke ukuthi sibuyisele imigqa yokupholisa eyengeziwe futhi sihambisane nesimiso sokupholisa se-pulsed. Lolo uhlobo lokulungisa izandla igama elithi 'ukunemba okuphezulu' okufunwa buthule.
Yilapho isizinda sethu sikhona ukubunjwa kwegobolondo futhi ukutshala imali ngoba ezinye izinsimbi empeleni wazisa umsebenzi wethu Mg die casting. Lezo zinqubo zonke zimayelana nokulawula okushisayo okucophelelayo kanye nokungena kwesango ukuze kuzuzwe ukuzinza kwe-dimensional. Sisebenzisa leyo filosofi yokulawula indlela yokuqinisa, ngesikhathi somjikelezo osheshayo kakhulu. Kungumqondo.
I-Die yiQhawe Elingasuliwe (noma I-villain)
Uma ufuna ukunemba okuphezulu kwe-magnesium alloy die casting, qala ngokutshala u-60% womzamo wakho nesabelomali ekwakhiweni kwefasi nokwakhiwa. Ukufa okuhle kwe-Mg akuyona nje insimbi eqinile.

Ukukhipha umoya kungobunye ubuciko obucashile. I-Mg idinga ukungenisa umoya okunamandla kune-aluminium ngenxa yokugcwala ngokushesha, kodwa izikhala kufanele zibekwe futhi zilinganiswe ukuze kugwenywe ukukhanya ngenkathi udedela umoya. Ezikhathini eziningi, ngiye ngabona ukufa lapho izintuba zezikhala zibe yinto ecatshangelwe kamuva, okuholela emaphaketheni egesi ashisiwe abukeka njengamaphutha angaphezulu futhi awonakele. ukunemba okuphezulu imfuneko yokuqeda phezulu. Ibhalansi phakathi kwejubane lokugcwalisa nokusebenza kahle kokukhipha umoya okufunda kuphela ngokudubula izingxenye eziningi ezimbi kuqala.
Sisebenzisane nesitolo samathuluzi endaweni yokufa yengxenye ye-drone engasindi. Umklamo wokuqala wawunamasango e-aluminium ezincwadi zokufunda. Sahlehla, siphikelela ohlelweni lwesango labalandeli olunesu elibukhali lokuchichima eliqondiswe kuzimpawu zokugeleza kukaMg. Isitolo samathuluzi sasingabaza—sasiyinkimbinkimbi ngokwengeziwe emshinini. Kodwa isivuno sokuqala ezingxenyeni ezinhle zeqe ngo-40%. Lowo umsebenzi ongokoqobo, ongabukhazisi ngemuva kwegama elingukhiye.
Imishini: Lapho Ukunemba Kugcine Kugcwaliseka Khona
Yilapho indlela edidiyelwe ye-QSY ikhanya khona. Cha ukunemba okuphezulu kwe-magnesium alloy die casting inqubo kuqedile ngaphandle kokucabangela machining. Ukulingisa kukuthola u-95% lapho; I-CNC machining ikhiya ku-5% wokugcina wokunemba. Kodwa ukwenza uMg kuyisilwane esihlukile. Akufani nokwenza ama-alloys angenasici noma asekelwe ku-nickel esiphinde siphathe. Ama-Mg chips ayakwazi ukuvutha, ngakho ukukhetha okupholile kanye nokukhishwa kwe-chip kubaluleke kakhulu ngokuphepha. Futhi awukwazi ukusebenzisa izingcindezi ezifanayo zokulungisa—i-Mg ithambile, ngakho-ke uzohlanekezela ingxenye uma ugoqa kakhulu, uphonsa konke ukunemba kokukhipha ngefasitela.
Siklama izinto zokulingisa kanye nemishini yokulungisa ngokuhambisana. Singase sengeze amaphedi amancane, okomhlatshelo okubeka endaweni yokulingisa ngokukhethekile ukuze i-vise ye-CNC ibambe, aqedwe ekusebenzeni kokugcina. Lokhu kuqinisekisa ukuthi ingxenye ibhekiselwa kudathamu yayo, ayihlanekezelwa amandla okubamba. Isinyathelo esengeziwe, kodwa ukuphela kwendlela yokushaya ngokuthembekile lokho kubekezelelana okungu-±0.025mm endlini enezindonga ezincane.
Ukwehluleka esikufunde kukho: sake sasebenza ngomshini inqwaba yezingxenye ze-AZ91D zomile ukuze ziqedelwe kangcono. Ukushisa okuvela emishinini, kuhlanganiswe nothuli olucolekile, kudale ingozi yomlilo ecishe ibe khona. Manje, sisebenzisa isipholisi esithile sevolumu ephezulu, esinengcindezi ephansi ephatha ukushisa futhi sicindezele uthuli ngaphandle kokubangela ukugqwala endaweni esebenza ngomshini. Isifundo sifunde kabuhlungu.
