Intambo yendiza ikwabizwa ngokuba ngumsonto wesiphelo, kwaye imilo yezinyo layo iyafana nentambo yoxande, kodwa umsonto osicaba udla ngokuba ngumsonto ocutshungulwayo kwisiphelo sobuso be-cylinder okanye idiski.I-trajectory yesixhobo esijikayo xa kusenziwa intambo yenqwelomoya yiArchimedes spiral, eyahlukileyo kumsonto wecylindrical oqhele ukwenziwa ngoomatshini.Oku kufuna ujikelezo olunye lwe-workpiece, kwaye inqwelo ephakathi ihambisa i-pitch kwi-workpiece ecaleni.Apha ngezantsi siza kwazisa ngokuthe ngqo indlela yokujika imisonto yenqwelomoyaumatshiniinkqubo.
1. Iimpawu ezisisiseko zomsonto
Amalungu adibeneyo asetyenziswa ngokubanzi ngexesha lomatshini, kunye nemicu yangaphandle nangaphakathi.Kukho iintlobo ezine eziphambili ngokwemilo yeprofayili yomsonto: intambo engunxantathu, intambo yetrapezoidal, intambo edibeneyo kunye nentambo yoxande.Ngokwenani leentambo zomsonto: intambo enye kunye nemisonto emininzi.Kwimitshini eyahlukeneyo, imisebenzi yamacandelo afakwe intambo ibandakanya oku kulandelayo: enye yeyokuzila kunye nokudibanisa;enye yeyokuhambisa amandla kunye nokutshintsha uhlobo lwesindululo.Iintambo ezinxantathu zihlala zisetyenziselwa ukudibanisa kunye nokomelela;I-trapezoidal kunye ne-rectangular threads zihlala zisetyenziselwa ukuhambisa amandla kunye nokutshintsha indlela yokunyakaza.Iimfuno zabo zobugcisa kunye neendlela zokucubungula zine-gap ethile ngenxa yokusetyenziswa kwazo ezahlukeneyo.
2. Indlela yokucubungula intambo yendiza
Ukongeza ekusebenziseni izixhobo zoomatshini eziqhelekileyo, ukuze kuncitshiswe ngokufanelekileyo ubunzima bokucutshungulwa kweentambo zomatshini, ukuphucula ukusebenza kakuhle, kunye nokuqinisekisa umgangatho wokucutshungulwa kwentambo, i-CNC machining isoloko isetyenziswa.
Umyalelo emithathu ye-G32, i-G92 kunye ne-G76 idla ngokusetyenziswa kwizixhobo zoomatshini be-CNC.
Umyalelo G32: Iyakwazi ukucubungula intambo ye-stroke enye, umsebenzi weprogram enye unzima, kwaye inkqubo inzima kakhulu;
Umyalelo we-G92: Umjikelo olula wokusika umsonto unokufezekiswa, oluncedo ekwenzeni lula ukuhlelwa kwenkqubo, kodwa ufuna i-workpiece engenanto ukuba irhangqwe kwangaphambili.
Umyalelo we-G76: Ukoyisa iintsilelo zoMyalelo we-G92, i-workpiece inomatshini ukusuka kwi-blank ukuya kwintambo egqityiweyo ngexesha elinye.Ukugcina ixesha lenkqubo luncedo olukhulu ekwenzeni lula inkqubo.
I-G32 kunye ne-G92 ziindlela zokusika ngokuthe tye, kwaye imida emibini yokusika kulula ukuyinxiba.Oku kubangelwa ikakhulu kumsebenzi ofanayo wamacala amabini e-blade, amandla amakhulu okusika kunye nobunzima bokusika.Xa intambo ene-pitch enkulu inqunywe, umgca wokusika unxiba ngokukhawuleza ngenxa yobunzulu obukhulu bokusika, obangela impazamo kububanzi bomtya;nangona kunjalo, ukuchaneka kobume bezinyo olucwangcisiweyo kuphezulu, ngoko ke isetyenziselwa ukusetyenzwa komsonto omncinci wepitch.Ngenxa yokuba ukusika intshukumo yesixhobo kugqitywe ngokucwangcisa, inkqubo yomatshini ide, kodwa iguquguquka ngakumbi.
I-G76 yeyendlela yokusika i-oblique.Ngenxa yokuba yinkqubo yokusika i-single-side, i-cut cut edge ilula ukuba yonakaliswe kwaye igqitywe, ukwenzela ukuba i-threaded surface ye-machining ingabi ngqo.Ukongezelela, emva kokuba i-angle yokusika itshintshile, ukuchaneka kobume bezinyo kubi.Nangona kunjalo, inzuzo yale ndlela yomatshini kukuba ubunzulu bokusika buyancipha, umthwalo wesixhobo uncinci, kwaye ukususwa kwe-chip kulula.Ngoko ke, indlela yokucubungula ifanelekile ukucutshungulwa kwemicu emikhulu ye-pitch.
