Intshayelelo kunye nezicelo zokusetyenziswa kwe-drill engenanto

Amasuntswana obhobhozo (i-multi-edge steel plate drills, ekwabizwa ngokuba yi-core drills) ngamasuntswana okomba asebenzayo okusikwa kwesetyhula.Ububanzi bokomba buqala kwi-12mm ukuya kwi-150mm.Ikakhulu isetyenziselwa ukomba amacandelo entsimbi, njengobunjineli besakhiwo sentsimbi kunye nokuhamba ngololiwe., iibhulorho, iinqanawa, ukwenziwa koomatshini, i-aerospace kunye namanye amasimi okulungisa umngxuma, ukusebenza kwawo kokomba kubhetele kakhulu kunesithethe.I-al-edged twist drill, eneempawu eziphezulu zokuqhuba, ukukhanya kunye nokugcina umsebenzi wokugaya, i-multi-edged steel plate drill kunye ne-magnetic seat drill Isixhobo esihambelanayo sinokwenza u-multi-directional drilling of workpieces ezinkulu.Umsebenzi ulungele kwaye uguquguqukayo, unciphisa ngokufanelekileyo ixesha lokwakha, kwaye uye waba sisixhobo sokuqala sokukhetha ukugaya kunye nokulungiswa kwe-groove ye-annular yamacandelo ensimbi yanamhlanje.

1.Impembelelo ekusikeniHlela uBroisibhengezo?

I-hollow drill bit sisixhobo sokulungisa umngxuma esilungele ngakumbi izixhobo eziphathwayo.Nangona kunjalo, ekubeni inkqubo yokuvelisa i-drills engenanto inzima kwaye ayikwazi ukwenza imingxuma eyimfama, ayiqhelekanga ukusetyenziswa kwintsimbi yokusika.Zidla ngokusetyenziswa kuphela xa kusetyenzwa ngemingxunya yobukhulu obukhulu okanye iintsimbi ezixabisekileyo zokusebenza okanye xa amandla ezixhobo zokomba elinganiselwe..Kuba kukho are akukho mveliso zisemgangathweni zomgobo wokubhola, uninzi lwamasuntswana ombhobho asetyenziselwa ukusetyenzwa kwemathiriyeli ekhethekileyo kufuneka iphuhliswe sithi.

I-engile yangasemva efisiphumo

2.Impembelelo yerakii-angle kumandla okusika?

Utshintsho kwi-rake angle luya kuchaphazela iqondo lokuguqulwa kwezinto ze-chip, ngaloo ndlela kubangele utshintsho kumandla okusika.Igukubuyisela i-chip deformation, amandla amakhulu okusika;incinci i-chip deformation, incinci amandla okusika.Xa i-angle ye-rake iguquka kuluhlu lwe-0 ° ukuya kwi-15 °, i-coefficient yokulungisa i-cutting force itshintsha kwi-1.18 ukuya kwi-1.

3.Impembelelo ye-engile yerakiekomeleleni kwesuntswana le-drill?

Xa ukwandisa i-engile ye-rake ye-drill bit, amandla kunye nomthamo wokutshatyalaliswa kobushushu besixhobo sesixhobo siya kuncitshiswa, kwaye kuya kuchaphazela uxinzelelo kwi-tip yesixhobo.Xa i-engile yeharika ilixabiso elincomekayo, incam yesixhobo ixhomekeke ku-to Uxinzelelo lwengqondo;xa i-engile yeraki ilixabiso elibi, incam yesixhobo iphantsi koxinzelelo olucinezelayo.Ukuba i-angle yeraki ekhethiweyo inkulu kakhulu, nangona ubukhali be-drill bit bunganyuswa kwaye amandla okusika angancitshiswa, uxinzelelo lwe-tensile kwi-tip yesixhobo luya kuba lukhulu, amandla esixhobo sokucoca aya kuncitshiswa, kwaye iya kwaphuka ngokulula.Kwiimvavanyo zokusika, iibhithi ezininzi zokubhola zonakaliswe ngenxa ye-engile yeharika egqithisileyo.Nangona kunjalo, ngenxa yobunzima obuphezulu kunye namandla ezinto eziza kucutshungulwa, kunye nokuqina okuphantsi kwe-shaft engundoqo kunye nomatshini wonke we-drilling rig ephathekayo, ukuba i-angle yeraki ekhethiweyo incinci kakhulu, ukunyuka kwamandla okusika ngexesha lokomba. izakubangela ishaft engundoqo ukuba ingcangcazele, kwaye iintshukumo ezicacileyo ziyakuvela kumphezulu womatshini.imigca, ukuqina kwe-drill bit kuya kuncitshiswa.

5.Impembelelo yokusika i-permance

Ukwandisa i-angle yokucoca kunokunciphisa ukungqubuzana phakathi kwe-flank surface kunye nezinto zokusika kunye nokunciphisa i-extrusion deformation yomhlaba owenziwe ngomatshini.Nangona kunjalo, ukuba i-engile yokucoca inkulu kakhulu, i-blamandla e-ade kunye nomthamo wokutshatyalaliswa kobushushu uya kuncitshiswa.

Ubungakanani be-angle yokunceda buchaphazela ngokuthe ngqo ukuqina kwe-drill bit.Ngexesha lenkqubo yokomba, iindlela eziphambili zokunxiba ze-drill bits zizikrwelo zoomatshini kunye nokutshintsha kwesigaba.Ukuqwalasela i-abrasion yomatshini kunye nokugqoka, xa ubomi bokusika buhlala buhlala, i-angle yokucoca inkulu, ixesha elide lokusika elikhoyo;ukuqwalasela ukuguga kwesigaba, ukunyuka kwe-angle yokucoca kuya kunciphisa i-abil yokutshatyalaliswa kobushushuubume be-drill bit.Emva kokuba i-drill bit igugile, njengoko indawo yokunxiba kwiflanki isanda ngokuthe ngcembe kwaye amandla okusika anyuka ngokuthe ngcembe, ubushushu obuveliswa kukukhuhlana buya kukhula kancinci kancinci, bubangele ukunyuka kweqondo lobushushu.Xa iqondo lobushushu linyuka ukuya kwi-drill bit phase transition yeqondo lobushushu, i-drill bit izakuvela Nxiba ngokukhawuleza.

6.Isiphumo sokulolainkqubo

I-bit drill bit isebenzisa ubuninzi obuncinci kwaye ibhetshi yokucubungula incinci.Ke ngoko, imiba yetekhnoloji yokucubungula kufuneka iqwalaselwe xa kuyilwa i-drill bit, kwaye ukusetyenzwa kunye nokulola kufuneka kuphunyezwe ngezixhobo eziqhelekileyo zomatshini kunye nezixhobo eziqhelekileyo kangangoko kunokwenzeka.Iichips zihamba ngokusebenza ouion.Ngethuba lenkqubo yokuphuma, ii-chips zixutywe kwaye zixutywe nge-rake face, ezibangeladeformation ngakumbi.Intsimbi esemazantsi etshiphu ikhubazeke kakhulu kwaye ityibilika ecaleni kobuso beraki, yenze umaleko ongezantsi wetshiphu ube nde kwaye wenze iimilo ezahlukeneyo ezigoqeneyo.Xa usebenzisa umngxuma wokugrumba imingxuma, ufuna iitshiphusi zinqunyulwe zibe ziitshiphusi okanye imicu ukuququzelela ukususwa kwetshiphu.Ukuze kuququzelelwe ukusetyenzwa kunye nokulola, ubuso behariki kufuneka bucwangciswe njengomgangatho osicaba ngaphandle kwe-chip breaker.Umphezulu weraki awufuni kugaywa ngokutsha ngexesha lokusetyenziswa.Umphezulu weflanki wentwana yokubhora yeyona ilula ukuyicombulula kwaye ikwangumphezulu onesantya esikhawulezayo sokunxiba.Ke ngoko, ukulolwa kwe-drill drill bit kufezekiswa ngokulola umphezulu weflank.Umphezulu weflanki wesibini wahlulwe waba ngumgangatho wangaphakathi weflanki wesibini kunye nomphezulu weflanki wangaphandle.Ukususela kumbono wokugaya, akulula ukubuyisela i-flank yangaphakathi kunye yangaphandle ye-flank encedisayo, ngoko ke iindawo ezincedisayo ze-flank kufuneka zenziwe ukuba zingayi kuhlanjululwa.

7.Ukusika ulwelo kunye ne-drillamasuntswana

Into ephambili ye-drill drill bit kukuba i-core yangaphakathi yomngxuma ayinqunyulwa ngexesha lokucubungula.Ke ngoko, inani lokusika le-drill drill bit lincinci kakhulu kunelo le-twist drill, kwaye amandla okuqhuba afunekayo kunye nobushushu obuveliswayo ngexesha lokusika nazo zincinci.Xa kusetyenzwa ngamasuntswana obhobho entsimbi anesantya esiphezulu, ngenxa yokuba ubushushu bendawo yokusebenzela bunempembelelo enkulu kubulukhuni besixhobo sokomba, into yokupholisa kufuneka isetyenziswe ukupholisa ngexesha lenkqubo yokomba (ukuba akukho sipholisi sisetyenziswayo, ukomba Ukunxiba kancinci kuya kuba sisinxibo sokutshintsha kwesigaba kunye nokukhawuleza ekuqaleni. ukunxiba).Ekuqaleni, thinaed ukupholisa isitshizi sangaphandle.Nangona kunjalo, ngenxa yokuba isikhululo se-drill bit sicutshungulwa kwicala le-axis ethe tyaba, kunzima ukuba isipholileyo singene kumda wokusika we-drill bit.Ukusetyenziswa kokupholisa kukhulu kwaye umphumo wokupholisa awufanelekanga.Ulwakhiwo lwe-drill rig spindle luyilwe ngokutsha ukuze lutshintshe ukupholisa kwangaphandle kokutshiza ukuya kukupholisa kwangaphakathi kokutshiza.Isipholisi songezwa ukusuka kumbindi wentwana ye-drill, ukuze isipholileyo sifikelele ngokutyibilikayo kwindawo yokusika i-drill bit, ngaloo ndlela kuncitshiswe kakhulu ukusetyenziswa kwesipholisi kunye nokuphucula isiphumo sokuPholisa.
