Isingeniso kanye namathemba okusetshenziswa kokubhoboza okungenalutho

Ama-drill bits angenalutho (amapuleti ensimbi ane-multi-edge, eyaziwa nangokuthi ama-core drill) ayizinsimbi zokubhola ezisebenza kahle zokusika isiyingi esinamaphethelo amaningi.Ububanzi bokubhoboza busukela ku-12mm kuye ku-150mm.Ikakhulukazi isetshenziselwa ukumba izingxenye zensimbi, njengobunjiniyela besakhiwo sensimbi kanye nokuhamba kwesitimela., amabhuloho, imikhumbi, ukukhiqizwa kwemishini, i-aerospace nezinye izinkambu zokucubungula imigodi, ukusebenza kwayo kokumba kungcono kakhulu kunosiko.i-twist twist drill enezinhlangothi ezimbili, enezici zokusebenza kahle kokubhola, ukubhola okulula nokonga abasebenzi, ukubhola kwepuleti elinemiphetho eminingi kanye nokubhola kwesihlalo kazibuthe Ithuluzi elihambisanayo lingakwazi ukubhola izinhlangothi eziningi zezinto zokusebenza ezinkulu.Ukusebenza kulula futhi kuyavumelana nezimo, kufinyeza ngempumelelo isikhathi sokwakha, futhi sekube yithuluzi lokuqala lokukhetha lokumba kanye nokucutshungulwa kwe-annular groove yezingxenye zensimbi zesimanje.

1.Ithonya ekusikeniHlela Broukukhangisa?

I-hollow drill bit iyithuluzi lokucubungula imbobo elifaneleka kakhulu kumathuluzi aphathekayo.Kodwa-ke, njengoba inqubo yokukhiqiza izimbobo ezingenalutho iyinkimbinkimbi futhi ayikwazi ukucubungula izimbobo eziyimpumputhe, azivamile ukusetshenziselwa ukusika insimbi.Ngokuvamile zisetshenziswa kuphela lapho zicutshungulwa ngezimbobo ezinobubanzi obukhulu noma izinto zokusebenza zensimbi eziyigugu noma lapho amandla emishini yokumba elinganiselwe..Kusukela lapho afuthi ayikho imikhiqizo ejwayelekile yezinsimbi zokubhoboza ezingenalutho, izingcezu zokubhoboza ezingenalutho ezisetshenziselwa ukucubungula izinto ezikhethekile zidinga ukuthuthukiswa yithina.

I-engeli yangemuva efi-fect

2.Umphumela werakii-angle on cutting force?

Izinguquko ku-rake angle zizothinta izinga lokuguquguquka kwezinto ze-chip, ngaleyo ndlela kubangele izinguquko kumandla okusika.I-givuselela i-chip deformation, amandla amakhulu okusika;i-chip deformation encane, amandla okusika amancane.Lapho i-engeli yereki ishintsha kububanzi obungu-0° ukuya ku-15°, i-coefficient yokulungisa amandla okusika iyashintsha kububanzi obungu-1.18 ukuya ku-1.

3.Ithonya le-engeli yerakingokuqina kwe-drill bit?

Uma ukhuphula i-engeli ye-rake ye-drill bit, amandla kanye nevolumu yokuchitha ukushisa kwephuzu lethuluzi kuzoncishiswa, futhi kuzophinde kuthinte ingcindezi ethiphu yethuluzi.Uma i-engeli yeraki iyinani eliphozithivu, ithiphu lethuluzi lingaphansi kuka-to ukucindezeleka okuqinile;uma i-engeli ye-rake iyivelu engalungile, ithiphu yethuluzi ingaphansi kwengcindezi ecindezelayo.Uma i-engeli ye-rake ekhethiwe inkulu kakhulu, nakuba ubukhali be-drill bit bungakhushulwa futhi amandla okusika angancishiswa, ukucindezeleka okuqinile kwiphuzu lethuluzi kuzoba kukhulu, amandla wethiphu yethuluzi azoncishiswa, futhi izophuka kalula.Ezivivinyweni zokusika, izingcezu zokubhola eziningi zonakaliswa ngenxa ye-rake angle eyeqile.Kodwa-ke, ngenxa yokuqina okuphezulu namandla ezinto okufanele zicutshungulwe, kanye nokuqina okuphansi kwe-shaft eyinhloko kanye nomshini wonke we-drilling rig ephathekayo, uma i-rake angle ekhethiwe incane kakhulu, ukwanda kwamandla okusika ngesikhathi sokumba. kuzobangela ukuthi i-shaft eyinhloko idlidlize, futhi ukudlidliza okusobala kuzovela endaweni eyenziwe ngomshini.imigqa, ukuqina kwe-drill bit nakho kuzoncishiswa.

5.Umthelela wokusika i-permance

Ukwandisa i-angle yokususa kunganciphisa ukungqubuzana phakathi kwe-flank surface kanye nezinto zokusika futhi kunciphise ukuchithwa kwe-extrusion kwendawo esebenza ngomshini.Kodwa-ke, uma i-engeli yokususa inkulu kakhulu, i-blamandla e-ade namandla okukhipha ukushisa azoncishiswa.

Ubukhulu be-engeli yokusiza buthinta ngokuqondile ukuqina kwe-drill bit.Phakathi nenqubo yokumba, izindlela zokugqoka eziyinhloko zama-drill bits ama-mechanical scratches nokuguga koshintsho lwesigaba.Uma kucatshangelwa ukuhuzuka komshini kanye nokuguga, lapho impilo yokusika ingashintshi, i-angle yokukhipha inkulu, isikhathi sokusika esitholakalayo siba side;uma kucatshangelwa ukuguga koshintsho lwesigaba, ukwanda kwe-angle yokususa kuzonciphisa i-abil yokukhipha ukushisaubuncane be-drill bit.Ngemuva kokuthi i-drill bit isigugile, njengoba indawo egugile ehlangothini ikhula kancane kancane futhi amandla okusika akhula kancane kancane, ukushisa okukhiqizwa ukungqubuzana kuzokwanda kancane kancane, kubangele izinga lokushisa le-drill bit.Uma izinga lokushisa likhuphukela kuzinga lokushisa lokushintsha kwesigaba se-drill bit, i-drill bit izovela Gqoka ngokushesha.

6.Umphumela wokucijainqubo

I-hollow drill bit isebenzisa inani elincane futhi iqoqo lokucubungula lincane.Ngakho-ke, izinkinga zobuchwepheshe bokucubungula kufanele zicatshangelwe lapho uklama i-drill bit, futhi ukucubungula nokulola kufanele kufezwe ngemishini evamile yokwenza imishini namathuluzi avamile ngangokunokwenzeka.Ama-chips ageleza ukusebenza kwe-ouion.Phakathi nenqubo yokuphuma, ama-chips acindezelwa futhi ahlikihlwe yi-rake face, okubangelaenye deformation.Insimbi engaphansi kwe-chip ikhubazekile kakhulu futhi ishelela eduze kobuso bereki, okwenza ungqimba olungezansi lwe-chip lube lude futhi lwenza izimo ezigoqene ezihlukahlukene.Uma usebenzisa i-drill bit engenalutho ukuze ubhoboze izimbobo, ufuna ukuthi ama-chips asikwe abe ama-chips noma ama-strips ukuze kube lula ukukhishwa kwe-chip.Ukuze kube lula ukucutshungulwa kanye nokulola, ubuso bereki kufanele buklanywe njengendawo eyisicaba ngaphandle kwe-chip breaker.I-rake surface ayidingi ukugaywa kabusha ngesikhathi sokusetshenziswa.Indawo eseceleni ye-drill bit elula kakhulu ukuyigaya futhi ingaphezulu enezinga lokuguga elishesha kakhulu.Ngakho-ke, ukucijiswa kwe-drill bit engenalutho kufinyelelwa ngokulola indawo ye-flank.I-flank surface yesibili ihlukaniswe yaba indawo yangaphakathi ye-flank yesibili kanye nendawo yesibili ye-flank yangaphandle.Ngokombono wokugaya kabusha, akulula ukuphinda ugaye izindawo ezisizayo zangaphakathi nezingaphandle, ngakho-ke izindawo ezisizayo zeflank kufanele zidizayinelwe ukuthi zingaphinde zigaywe.

7.Ukusika uketshezi kanye nokubhobozaizingcezu

Isici esiyinhloko se-hollow drill bit ukuthi umgogodla wangaphakathi womgodi awunqunywa ngesikhathi sokucubungula.Ngakho-ke, inani lokusika le-drill drill bit lincane kakhulu kunalelo le-twist drill, futhi amandla okumba adingekayo kanye nokushisa okukhiqizwa ngesikhathi sokusika nakho kuncane.Lapho ubhoboza ngezingcezu zensimbi ezinezimbobo zensimbi ezinesivinini esikhulu, ngenxa yokuthi izinga lokushisa lendawo yokucubungula linethonya elikhulu ekuqineni kwendawo yokubhoboza, isipholile kufanele sisetshenziselwe ukupholisa ngesikhathi sokumba (uma kungasebenzisi isisipholisi, umshini wokubhola. ukugqoka kancane kuzoba ukuguga koshintsho lwesigaba futhi kusheshe ekuqaleni. ukuguga).Ekuqaleni, thinaed ukupholisa isifutho sangaphandle.Kodwa-ke, ngenxa yokuthi i-drill bit station icutshungulwa ngendlela ebheke eksisi evundlile, kuba nzima ngesipholile ukuthi singene onqenqemeni lwe-drill bit.Ukusetshenziswa kokupholisa kukhulu futhi umphumela wokupholisa awulungile.Isakhiwo sokuphotha se-drill rig siklanywe kabusha ukushintsha ukupholisa isifutho sangaphandle sibe ukupholisa kwangaphakathi kwesifutho.Isipholile sengezwa sisuka kunkaba ye-drill bit, ukuze isipholile sifinyelele ngokushelela engxenyeni yokusika ye-drill bit, ngaleyo ndlela kunciphisa kakhulu ukusetshenziswa kokupholisa nokwenza ngcono umphumela wokupholisa.
