I-Drill bit, njengesona sixhobo sixhaphakileyo ekuqhutyweni komngxunya, sisetyenziswa ngokubanzi kwimveliso yomatshini, ngakumbi ukulungiswa kwemingxuma kwizixhobo zokupholisa, i-tube sheets yezixhobo zokuvelisa amandla, iijenereyitha zomphunga kunye nezinye iindawo.
1,Iimpawu zokomba
I-drill bit idla ngokuba neekona ezimbini eziphambili zokusika.Ngexesha lomatshini, i-drill bit ijikeleza kwaye iyancipha ngexesha elifanayo.I-angle yangaphambili ye-drill bit iba nkulu kwaye ibe nkulu ukusuka kwi-axis esembindini ukuya kumda wangaphandle, isantya sokusika se-drill bit kufuphi nesangqa sangaphandle siphezulu, kwaye isantya sokusika siyancipha ukuya embindini, kunye nesantya sokusika i-drill. Iziko elijikelezayo le-drill bit ngu-zero.Umphetho othe tyaba we-drill ukufuphi ne-axis yeziko elijikelezayo.Umda wecala une-angle encedisayo enkulu, akukho ndawo ye-chip, kunye nesantya esisezantsi sokusika, ngoko kuya kuvelisa ukuxhathisa okukhulu kwe-axial.Ukuba umgca onqamlekileyo ugayiwe ukuze uthayiphe i-A okanye i-C kwi-DIN1414, kwaye i-cut cut kufuphi ne-central axis ine-angle ye-rake e-positive, ukuchasana kokusika kunokunciphisa kwaye ukusebenza kokusika kunokuphuculwa kakhulu.
Ngokweemilo ezahlukeneyo, izixhobo, izakhiwo kunye nemisebenzi yezixhobo zokusebenza, iidrill zinokwahlulwa zibe ziindidi ezininzi, ezifana ne-high-speed steel drills (i-twist drills, i-drill drills, i-flat drills), i-dills ye-carbide edibeneyo, i-indexable drills yemingxuma enzulu, enzulu. umngxuma drills, imikhono drills, kunye nokutshintshwa intloko drill.
2,Ukuqhekeka kwetshiphu kunye nokususwa kwetshiphu
Ukusikwa kwe-drill bit kuqhutyelwa kumngxuma omncinci, kwaye ii-chips kufuneka zikhutshwe kwi-groove yokusika i-drill bit, ngoko ke i-chip shape inempembelelo enkulu ekusebenzeni kokusika kwe-drill bit.Iimilo ze-chip eziqhelekileyo ziquka iitshiphusi ze-flake, iitshiphusi ze-tubular, iitshiphusi zenaliti, iitshiphusi ze-spiral tapered, iitshiphusi zeribhoni, iitshiphusi ezimilise okwefeni, iitshiphusi ze powdery, njl.
Xa i-chip shape ingafanelekanga, ezi ngxaki zilandelayo ziya kwenzeka:
①Iitshiphusi ezintle zithintela i-groove edge, zichaphazela ukuchaneka kokomba, zinciphisa ubomi be-drill bit, kwaye zide ziphule i-drill bit (ezifana ne-powdery chips, i-chips ezimilise fan, njl.);
②Iitshiphusi ezinde zibhijela intwana yoqheliso, zithintela ukusebenza, zibangela umonakalo kwisuntswana ledrili okanye zithintele ulwelo lokusika ukuba lungangeni emngxunyeni (njengeetshiphusi ezijikelezayo, iitshiphusi zeribhoni, njl. njl.).
Indlela yokusombulula ingxaki yesimo se-chip esingafanelekanga:
①Ukuqhekeka kwe-chip kunye nesiphumo sokususwa kwe-chip kunokuphuculwa ngokunyusa izinga lokutya, ukutya okuphakathi, ukugaya i-cross edge, ukufaka i-chip breaker, njl., ngokulandelanayo okanye ngokudibeneyo, ukuphelisa iingxaki ezibangelwa yi-chips.
②Uqheliso lobuchwephesha lokuqhekezwa kwetshiphu lunokusetyenziswa ekwembeni.Umzekelo, i-chip eyenzelwe i-edge yokwephulwa yongezwa kwi-groove ye-drill bit ukuphula iitshiphusi zibe yi-chips ezicocwe ngokulula.Ubutyobo buya kukhutshwa ngokutyibilikayo ecaleni komsele ngaphandle kokuvaleka kumsele.Ke ngoko, i-chip entsha yokuqhekezwa kwe-drill ifezekisa isiphumo sokusika esigudileyo kune-drill yendabuko.
Kwangaxeshanye, intsimbi emifutshane yentsimbi yenza ukuba kube lula ukuba i-coolant ihambe ukuya kwindawo yokubhobhoza, iphucule ngakumbi isiphumo sokutshatyalaliswa kobushushu kunye nokusika ukusebenza ngexesha lokucubungula.Ngaphezu koko, ngenxa yokuba i-chip esanda kufakwa kwi-edge eqhekezayo ingene kwi-groove yonke ye-drill bit, ukumila kwayo kunye nokusebenza kwayo kusenokugcinwa emva kwamaxesha amaninzi okusila.Ukongeza ekuphuculweni komsebenzi ongentla, kuyafaneleka ukukhankanya ukuba uyilo lomeleza ukuqina komzimba we-drill kwaye kwandisa kakhulu inani lemingxuma eqhutywe ngaphambi kokugaya enye.
3,Ukuchaneka kokomba
Ukuchaneka komngxuma ikakhulu kuqulunqwe yimiba efana nobukhulu bomngxuma, ukuchaneka kwendawo, ukubumbana, ukungqukuva, uburhabaxa bomphezulu kunye ne-hole burr.
Izinto ezichaphazela ukuchaneka komngxuma oza kusetyenziswa ngoomatshini ngexesha lokomba:
①Ukuchaneka kwe-clamping kunye neemeko zokusika ze-drill, ezifana nomphathi wesixhobo, isantya sokusika, izinga lokutya, ukusika ulwelo, njl.
②Ubungakanani besuntswana kunye nokumila, njengobude besuntswana, imilo yongqameko, imilo engundoqo, njl.njl;
③Imilo ye-workpiece, efana ne-orifice side shape, i-orifice shape, ubukhulu, i-clamping state, njl.
I-Counterbore
Ukubuyisela kwakhona kubangelwa kukujingiwa kwe-drill bit ngexesha lokucubungula.I-swing yomphathi wesixhobo inempembelelo enkulu kububanzi bomngxuma kunye nokuchaneka kokubeka umngxuma.Ke ngoko, xa isibambi sesixhobo sinxitywe kakhulu, isibambi sesixhobo esitsha kufuneka sitshintshwe ngexesha.Xa ubhobhoza imingxuma emincinci, kunzima ukulinganisa kunye nokulungelelanisa i-swing, ngoko ke kungcono ukusebenzisa i-drill ye-shank encinci ye-diameter drill kunye ne-coaxiality elungileyo phakathi kwe-blade kunye ne-shank.Xa usebenzisa i-regrind drill kwi-process, isizathu sokuhla kokuchaneka komngxuma kuninzi ngenxa ye-asymmetry ye-back shape.Ulawulo lomahluko wobude bomphetho unokunqanda ngokufanelekileyo ukuphinda kuphinde kuphinde kuphinde kuphinde kuphinde kuphinde kumiswe umngxuma.
Ukujikeleza komngxuma
Ngenxa yokunyakaza kwe-drill bit, umgodi owenziweyo kulula ukuba ube yi-polygonal, kwaye udonga lomngxuma lubonakala njengephethini yomgca ophindwe kabini.Imingxunya yepolygonal eqhelekileyo idla ngokuba ngunxantathu okanye ipentagonal.Isizathu somngxuma we-triangular kukuba i-drill bit inamaziko amabini ajikelezayo xa ubhobhoza, kwaye i-vibrate kwi-frequency exchange exchange every 600. Isizathu esona sizathu sokungcangcazela kukuba ukuchasana kokusika akulingani.Xa i-drill bit ijikeleza kanye, ngenxa yokujikeleza okungahambi kakuhle komngxuma osetyenzisiweyo, ukuchasana kungenakulinganisela ngexesha lokujikeleza kwesibini kokusika.Ukungcangcazela kokugqibela kuphinda kuphindwe kwakhona, kodwa isigaba sokungcangcazela sinokutenxa okuthile, okubangela imigca emibini eludongeni lomngxuma.Xa ubunzulu bokomba bufikelela kwinqanaba elithile, ukungqubana phakathi komphetho we-drill edge kunye nodonga lomngxuma luyanda, i-vibration iyancipha, i-involute iyanyamalala, kwaye ukujikeleza kuba ngcono.Olu hlobo lomngxuma lumiliselwe kwifunnel ukusuka kwicandelo lelongitudinal.Ngesizathu esifanayo, i-pentagon kunye ne-heptagon imingxunya inokuvela kwakhona ekusikeni.Ukuze kupheliswe le nto, ukongeza ekulawuleni izinto ezinje nge-collet vibration, umahluko wobude bomda, kunye nemilo ye-asymmetric yomqolo kunye ne-blade, kufuneka kuthathwe amanyathelo okuphucula ukuqina kwe-drill bit, ukonyusa izinga lesondlo revolution, nciphisa i-engile yangasemva, kwaye ugaye umgca we-cross.
Gqoka imingxuma kumathambeka nangaphezulu
Xa umphezulu wokusika okanye u-drilling ngokusebenzisa umphezulu we-drill bit uthambekele, ugobile okanye unyathelwe, ukuchaneka kokumisa kubi.Ngeli xesha, i-drill bit inqunyulwa kwicala elilodwa le-radial, elinciphisa ubomi besixhobo.
Ukuphucula ukuchaneka kokubeka, la manyathelo alandelayo anokuthathwa:
1. Gqoka umngxuma osembindini kuqala;
2. Lula isihlalo somngxuma ngelitye lokusila;
3. Khetha amasuntswana e-drill ngokungena okulungileyo kunye nokuqina;
