Kuyini ukugaya i-plunge?Iyini ukusetshenziswa ekucubunguleni?

▉Inzuzo

I-Plunge milling inikeza izinzuzo ezilandelayo:

①Inganciphisa ukuwohloka kwe-workpiece;

②Kunganciphisa amandla okusika e-radial asebenza emshinini wokugaya, okusho ukuthi i-spindle ene-shafting egugile isengasetshenziselwa ukugaya ngaphandle kokuphazamisa ikhwalithi yomshini womsebenzi wokusebenza;

③I-overhang yethuluzi inkulu, Okuzuzisa kakhulu ekugayweni kwemisele noma indawo engaphezulu;

④ Ingabona ukugqwala kwezinto ezisetshenziswayo zengxubevange yezinga lokushisa eliphezulu (njenge-Inconel).I-Plunge Milling ilungele imigodi yesikhunta emagebhugebhu futhi iyanconywa ukuze kusetshenziswe kahle izingxenye ze-aerospace.Okunye okusetshenziswayo wukucwiliswa kwama-turbine blade emishinini yokugaya enezinhlangothi ezintathu noma ezine, ngokuvamile edinga amathuluzi omshini akhethekile.

▉Isimiso sokusebenza

Lapho uphonsa i-turbine blade, ingagaywa ukusuka phezulu kwendawo yokusebenza kuze kufike empandeni ye-workpiece, futhi amajiyometri angaphezulu ayinkimbinkimbi kakhulu angenziwa ngomshini ngokuhumusha okulula kwendiza ye-XY.Uma ukucwiliswa kwenziwa, umkhawulo wokusika we-milling cutter wakha ngokudlula amaphrofayili okufakwayo.Ukujula kokuphonseka kungafinyelela ku-250mm ngaphandle kokuxoxa noma ukuhlanekezela.Isiqondiso sokusika sokunyakaza kwethuluzi elihlobene nendawo yokusebenza ingaba phansi noma phansi.Ukuya phezulu, kodwa ngokuvamile ukusika phansi kuvame kakhulu.Lapho ephonsa indiza ethambekele, umsiki ophonsayo wenza ukunyakaza okuhlanganisiwe ku-Z-axis kanye ne-X-eksisi.Kwezinye izimo zokucubungula, izisiki zokugaya eziyindilinga, izisiki zokugaya ubuso noma ezinye izisiki zokugaya zingasetshenziselwa ukucubungula okuhlukahlukene njengokugaya i-slot, ukugaya iphrofayili, ukugaya i-bevel, kanye nokugaya i-cavity.

▉Ububanzi besicelo

Abasiki be-plunge abazinikele basetshenziselwa ngokuyinhloko ukwenza ama-rough noma ukuqeda kancane, ukusika phakathi nendawo noma ukusika unqenqema lwe-workpiece, kanye namajiyometri ayinkimbinkimbi yokugaya, okuhlanganisa nokumba izimpande.Ukuqinisekisa izinga lokushisa eliqhubekayo lokusika, bonke abasiki be-shank plunging bapholiswa ngaphakathi.Umzimba wokusika kanye nokufakwa komsiki we-plunging kuklanywe ngendlela yokuthibonaungasika ku-workpiece nge-engeli engcono kakhulu.Ngokuvamile, i-engeli enqenqemeni yokusika ye-plung cutter ingu-87° noma 90°, futhi izinga lokuphakelayo lisukela ku-0.08 kuye ku-0.25mm/izinyo.Inani lezinto ezifakiwe okufanele ziboshwe kusisiki sokugaya ngasinye sincike kububanzi besisiki sokugaya.Isibonelo, i-milling cutter enobubanzi obungu-φ20mm ingafakwa ukufaka okungu-2, kuyilapho i-milling cutter enobubanzi be-f125mm ingafakwa ukufaka okungu-8.Ukuze unqume ukuthi umshini womshini othile wokusebenza ufanelekile yini ukugaya, izidingo zomsebenzi womshini kanye nezici zomshini womshini osetshenzisiwe kufanele kucatshangelwe.Uma umsebenzi womshini udinga izinga eliphezulu lokususwa kwensimbi, ukusetshenziswa kokugaya kunganciphisa kakhulu isikhathi somshini.

Esinye isikhathi esifanelekile sendlela yokuphonseka yilapho umsebenzi womshini udinga ubude be-axial obukhulu bethuluzi (njengokugaya izimbotshana ezinkulu noma ama-grooves ajulile), njengoba indlela yokuphonsa inganciphisa ngempumelelo amandla okusika ama-radial, uma kuqhathaniswa nokugaya. indlela, inokusimama okuphezulu kwemishini.Ngaphezu kwalokho, lapho izingxenye ze-workpiece ezidinga ukusikwa kunzima ukufinyelela kuzo ngezindlela ezivamile zokugaya, ukugaya i-plung nakho kungacatshangelwa.Njengoba umsiki we-plunging angasika insimbi aye phezulu, amajiyometri ayinkimbinkimbi angagaywa.

Ngokombono wokusebenza kwethuluzi lomshini, uma amandla omshini wokucubungula osetshenzisiwe elinganiselwe, indlela yokugaya i-plunge ingacatshangelwa, ngoba amandla adingekayo ekugayweni kwe-plunge angaphansi kwalawo okugaya i-helical, ngakho-ke kungenzeka ukusebenzisa. amathuluzi omshini amadala noma amathuluzi omshini angaphansi kwamandla ukuze uthole ukusebenza okungcono.Ukusebenza kahle okuphezulu kokucubungula.Isibonelo, ukuphonsa ama-grooves ajulile kungafinyelelwa ethuluzini lomshini we-40, elingafaneleki ukukhanda ngama-helical cutters amade, ngoba amandla okusika ama-radial akhiqizwa ukugaya i-helical makhulu, okulula ukwenza i-helical Ukugaya. ama-cutter vibrates.

I-Plunge Milling ilungele imishini emidala enama-spindle bearings ngenxa yamandla aphansi okusika ama-radial ngesikhathi sokucwila.Indlela yokugaya i-plunge isetshenziselwa ikakhulukazi ukukhanda okungalungile noma ukuqeda kancane, futhi inani elincane lokuchezuka kwe-axial okubangelwa ukuguga kwesistimu ye-shaft yethuluzi lomshini ngeke kube nomthelela omkhulu kwikhwalithi yomshini.Njengohlobo olusha lwe-CNC machining method,iindlela yokugaya i-plunge ibeka phambili izidingo ezintsha zesoftware yemishini ye-CNC.
