Indlela yokuguqula izintambo zendiza kunqubo yomshini?

Intambo yendiza ibizwa nangokuthi intambo yokuphela, futhi isimo sayo sezinyo siyafana nentambo engunxande, kodwa intambo eyisicaba ngokuvamile iyintambo ecutshungulwayo ekupheleni kobuso be-cylinder noma i-disc.I-trajectory yethuluzi elijikayo elihlobene nendawo yokusebenza lapho kwenziwa intambo yendiza i-Archimedes spiral, ehlukile kunentambo yesilinda evame umshini.Lokhu kudinga ukuphenduka okukodwa kwe-workpiece, futhi inqola ephakathi ihambisa i-pitch ku-workpiece eceleni.Ngezansi sizokwethula ngokuqondile indlela yokuvula imicu yendizaimishiniinqubo.

1. Izici eziyisisekelo zentambo

Amajoyinti anemicu asetshenziswa kakhulu ngesikhathi somshini, ngemicu yangaphandle neyangaphakathi.Kunezinhlobo ezine eziyinhloko ngokusho kokuma kwephrofayili yentambo: intambo engunxantathu, intambo ye-trapezoidal, intambo e-serrated kanye nentambo engunxande.Ngokwenombolo yezintambo zochungechunge: intambo eyodwa kanye nentambo enezintambo eziningi.Emishinini ehlukahlukene, imisebenzi yezingxenye ezinentambo ngokuyinhloko ihlanganisa lokhu okulandelayo: eyodwa iwukubopha nokuxhuma;enye ingeyokudlulisa amandla kanye nokushintsha indlela yokunyakaza.Imicu engunxantathu ivame ukusetshenziselwa ukuxhumana nokuqina;Izintambo ze-trapezoidal kanye ne-rectangular zivame ukusetshenziselwa ukudlulisa amandla nokushintsha indlela yokunyakaza.Izidingo zabo zobuchwepheshe kanye nezindlela zokucubungula zinegebe elithile ngenxa yokusetshenziswa kwazo okuhlukile.

2. Indlela yokucubungula intambo yendiza

Ngaphezu kokusetshenziswa kwamathuluzi omshini ojwayelekile, ukuze kuncishiswe ngempumelelo ubunzima bokucubungula imicu yokwenza, ukuthuthukisa ukusebenza kahle komsebenzi, nokuqinisekisa ikhwalithi yokucubungula intambo, i-CNC machining ivame ukusetshenziswa.

Imiyalo emithathu ye-G32, G92 ne-G76 ivame ukusetshenziselwa amathuluzi omshini we-CNC.

I-Command G32: Ingakwazi ukucubungula intambo ye-stroke eyodwa, umsebenzi wokuhlela owodwa unzima, futhi uhlelo luyinkimbinkimbi kakhulu;

Umyalo G92: Umjikelezo olula wokusika intambo ungenziwa, okuwusizo ekwenzeni kube lula ukuhlela uhlelo, kodwa udinga ukuthi ucezu lokusebenza olungenalutho lufakwe rough ngaphambili.

I-Command G76: Ngokunqoba ukushiyeka kwe-Command G92, i-workpiece ingenziwa ngomshini isuka engenalutho iye emculweni oqediwe ngesikhathi esisodwa.Ukonga isikhathi sokuhlela kuwusizo olukhulu lokwenza uhlelo lube lula.

I-G32 ne-G92 izindlela zokusika eziqondile, futhi imiphetho emibili yokusika kulula ukuyigqoka.Lokhu kubangelwa ikakhulukazi umsebenzi ngesikhathi esisodwa wezinhlangothi ezimbili ze-blade, amandla amakhulu okusika kanye nobunzima bokusika.Lapho intambo ene-pitch enkulu inqunywa, umkhawulo wokusika ugqoka ngokushesha ngenxa yokujula okukhulu kokusika, okubangela iphutha ububanzi bentambo;kodwa-ke, ukunemba kwesimo sezinyo elicutshunguliwe kuphezulu, ngakho-ke ngokuvamile kusetshenziselwa ukucubungula intambo encane ye-pitch.Ngenxa yokuthi ukusika ukunyakaza kwamathuluzi kuqedwa ngokuhlelwa, uhlelo lomshini lude, kodwa luvumelana nezimo.

I-G76 ingeyendlela yokusika i-oblique.Ngenxa yokuthi kuyinqubo yokusika ohlangothini olulodwa, umkhawulo ofanele wokusika kulula ukulimaza futhi ugqoke, ukuze indawo ehlanganisiwe yomshini ingaqondile.Ngaphezu kwalokho, uma i-angle enqenqemeni yokusika ishintsha, ukunemba kwesimo sezinyo kubi.Kodwa-ke, inzuzo yale ndlela yomshini yukuthi ukujula kokusika kuyancipha, umthwalo wethuluzi uncane, futhi ukukhishwa kwe-chip kulula.Ngakho-ke, indlela yokucubungula ifanele ukucutshungulwa kwezintambo ezinkulu ze-pitch.
