Izikhunta zokushisela ze-ultrasonic zicutshungulwa esithandweni sokushisa esikhethekile se-vacuum.
Izikhunta ze-Ultrasonic kanye nezikhunta zensimbi ze-ultrasonic ziyizingxenye eziyinhloko zemishini yokushisela ye-ultrasonic, futhi ukunemba kobuso bazo, ubulukhuni, kanye nokumelana nokuguguleka kunquma ngqo ikhwalithi yokushisela. Enqubweni yokukhiqiza izikhunta zensimbi, ukwelashwa kokushisa nge-vacuum esithandweni esikhethekile kuyisinyathelo esibalulekile ekuthuthukiseni ukusebenza kwesikhunta sensimbi. I-Shenzhen Chengguan Intelligent Ultrasonic Co., Ltd. (ezobizwa ngokuthi "i-Chengguan Intelligent"), njengomhlinzeki ochwepheshe wemishini yokushisela ye-ultrasonic kanye nezikhunta eShayina, ifinyelele intuthuko ephindwe kabili ekunembileni nasekuphileni kwesikhathi kwesikhunta sensimbi ngezinqubo zesithando sokushisa esenziwe ngokwezifiso.
I. Izidingo Eziyinhloko Zezikhunta Zensimbi Ze-Ultrasonic Zokwelashwa Kokushisa
Izikhunta zensimbi ze-ultrasonic zivame ukwenziwa insimbi yokubumba (njenge-SKD11, DC53) futhi zidinga ukumelana nokudlidliza okuvama kakhulu, ukungqubuzana, kanye nomthelela, ngakho-ke zinezidingo eziqinile zokwelashwa kokushisa.
- Ubulukhuni obuphezulu : Ubulukhuni bomphezulu budinga ukufinyelela ku-HRC58~62 ukuqinisekisa ukumelana nokuguguleka;
- Ukuguquguquka okuphansi : Ukunemba kwesikhunta sensimbi kumele kulawulwe ngaphakathi kuka-0.01mm, futhi ukuguquguquka ngemva kokwelashwa kokushisa kumele kube
- Ayinayo i-oxidation : Ubuso besikhunta sensimbi kumele bugcinwe bubushelelezi ukuze kugwenywe ukuthinta ukunemba ngesikhathi sokugaya okulandelayo.
Ukwelashwa kokushisa kwendabuko kungaholela kalula ekushiseni nasekuguquguqukeni ngokweqile kwesikhunta sensimbi, kuyilapho i-Chengguan Intelligent isebenzisa isithando sokushisa se-vacuum esenziwe ngokwezifiso , okuhambisana kahle nalezi zidingo.
II. Ukucushwa Kwenziwe Ngokwezifiso Kwesithando Sokushisa Sokushisa Se-Chengguan Intelligent Vacuum
Ukuze kuhlangatshezwane nosayizi omncane kanye nezici ezinembile kakhulu zezikhunta zensimbi ze-ultrasonic, i-Chengguan Intelligent, ngokubambisana nabakhiqizi bemishini, iklanyelwe ngendlela oyifisayo isithando sokushisa esincane sokuhlanza nge-vacuum esinembile ngokucushwa okulandelayo okuyinhloko:
- Amapharamitha esithando somlilo : usayizi osebenzayo φ200×300mm, ofanele ukucutshungulwa kwenqwaba yezikhunta zensimbi eziyi-10~15 ngenqwaba ngayinye;
- Uhlelo lokuhlanza : Iyunithi yepompo yama-molecule isetshenziselwa ukugcina i-vacuum ezinzile engu-5×10⁻³Pa, ngaleyo ndlela ivimbele ukushiswa kobuso besikhunta sensimbi;
- Uhlelo lokulawula izinga lokushisa : Izindawo ezi-4 zokulawula izinga lokushisa ezizimele, ukufana kwezinga lokushisa ±1℃, okuqinisekisa ubulukhuni obuqhubekayo kuzo zonke izindawo zesikhunta sensimbi;
- Uhlelo lokupholisa : ukucima igesi okuhleliwe (ukupholisa okusheshayo kokuqala nge-nitrogen eyi-1MPa, bese kuba ukupholisa kancane nge-0.3MPa) ukunciphisa ukuguquguquka kokucindezeleka kokushisa.
III. Ukugeleza Kwenqubo Yesithando Sokushisa Sokushisa Sensimbi Esine-Ultrasonic (Umkhuba Ohlakaniphile waseChengguan)
I-Chengguan Intelligent ihlanganisa ukwelashwa kokushisa kwe-vacuum kuyo yonke inqubo yokukhiqiza isikhunta sensimbi. Izinyathelo ezithile yilezi ezilandelayo:
1.Uma ishaja isithando somlilo, isikhunta sensimbi silungiswa ngomshini we-CNC, bese kuhlanzwa uwoyela ongaphezulu kanye nama-burrs. Bese kubanjiswa kusetshenziswa umshini wokubopha we-graphite
Kwenziwe ngokwezifiso yiChengguan Intelligent (ukugwema ukuthi isikhunta sensimbi sinamathele ku-clamping factory) futhi sihlelwe ngokulinganayo kuthreyi yokushaja yesithando somlilo.
2.ukuhlanza nokushisa , bese uvala umnyango wesithando somlilo, qala ngokususa i-vacuum uye ku-vacuum ephansi (10⁻¹Pa) ukuze ususe umoya, bese uphakamisa i-vacuum iye ezingeni eliqondiwe (5×10⁻³Pa); shisa ku-850℃
ngesilinganiso esingu-5℃/min bese ubamba imizuzu engama-20 (ukuze kuhlangatshezwane nezidingo ze-austenitization zezinto ze-SKD11).
3.Ukucima i-vacuum Kwenziwa ngokupholisa ngokushesha isikhunta sensimbi ngegesi ye-nitrogen ehlanzekile kakhulu engu-1MPa, kunciphisa izinga lokushisa kusuka ku-850℃ kuya ku-200℃ (izinga lokupholisa lingu-15℃/s). Bese,
izinga lokushisa lishintshelwa ku-0.3MPa igesi ye-nitrogen ukuze kuphole kancane liye ekamelweni lokushisa ukuze kugwenywe ukugxilisa ingqondo.
4.ukufudumala kwe-vacuum kanye Uma isicinywa, isikhunta sensimbi sibuyiselwa esithandweni esikhethekile, sishiswe ku-200℃, bese sigcinwa imizuzu engama-60 ukuze kuqedwe ukucindezeleka kwangaphakathi futhi kuzinze.
ubukhulu besikhunta sensimbi (i-Chengguan Intelligent ilawula ukuguquguquka kwesikhunta sensimbi kube ngaphakathi kuka-0.003mm ngale nqubo).
5.isithando somlilo , ubuso besikhunta sensimbi bukhanya futhi abunawo umoya. Ngemva kokudlula isivivinyo sokuqina (HRC60±1) kanye nesivivinyo sokunemba (isithwebuli se-3D), singena enkambisweni elandelayo yokupholisha.
6.IV. Inani Lobuchwepheshe Lokwelashwa Kokushisa Kwe-Vacuum Ezitsheni Ezizinikele (Isifundo Secala Esihlakaniphile saseChengguan)
Ngenqubo yesithando sokushisa esenziwe ngokwezifiso se-vacuum, isikhunta sensimbi esisebenza nge-ultrasonic se-Chengguan Intelligent sifinyelele:
- Isikhathi sokuphila esinwetshiwe : Isilinganiso sempilo yesevisi yezikhunta zensimbi sinyusiwe kusukela emijikelezweni yokushisela engu-50,000 enkambisweni yendabuko kuya emijikelezweni engu-120,000;
- Ukunemba okuzinzile : Ukuphindaphindwa kwesikhunta sensimbi kugcinwa ngaphakathi kuka-0.01mm, futhi isivuno semikhiqizo ehlanganisiwe sithuthukiswa sibe ngu-99.5%;
- Ukwehliswa kwezindleko : Ukuncipha kwezinqubo zokugaya nokulungisa kabusha okulandelayo kuye kwehlisa izindleko zokukhiqiza isikhunta sensimbi esisodwa ngo-15%.
Njengebhizinisi eliqhutshwa ubuchwepheshe emkhakheni wokushisela nge-ultrasonic, i-Chengguan Intelligent ihlanganise ngokujulile ubuchwepheshe besithando sokushisa se-vacuum.
ekukhiqizeni isikhunta sensimbi ngokusebenzisa ukwakheka okuhlanganisiwe "kwemishini + inqubo yesikhunta +", okuhlinzeka ngezixazululo zokushisela ze-ultrasonic ezithembeke kakhulu zezimboni ezifana ne-elekthronikhi, izindwangu, nezimoto.
