I-Drill bit iwuhlobo lwehardware esetshenziswa kakhulu emishinini yethu yokwakha.Isetshenziselwa ukubhoboza izimbobo noma izimbobo ezingaboni ezintweni eziqinile, futhi ingakhulisa izimbobo ezikhona.
Kodwa-ke, izinhlobo zama-drill bits esizikhethayo zihlukile ezindaweni zokusebenza ezihlukene.Izingcezu zokubhola ezivame ukusetshenziswa kakhulu zihlanganisa i-twist drill, i-flat drill, i-centre drill, i-deep hole drill kanye ne-nesting drill.
Ngakho-ke Hlobo luni lokubhola olusetshenziselwa ukubhola amapuleti ensimbi?
I-speed steel bit iyanconywa ukubhola ipuleti lensimbi.
Ngaphezu kwalokho, lapho ubhoboza, kuncike kububanzi bomgodi.Uma imbobo inkulu, amandla omshini kagesi okufanele asetshenziswe azoba makhulu.
Manje sekune-drill plate yensimbi ekhethekile (ebizwa nangokuthi i-hollow drill bit noma i-Annular cutter noma i-broach cutter noma i-core drill noma i-core cutter ), engabhola ngokushesha okukhulu.
Induku yokuxhuma ingafakwa ngokuqondile ku-drill kazibuthe, futhi amapuleti ensimbi awugqinsi angama-20 mm angabhola ngemizuzwana embalwa.Inezinzuzo ezisobala
I-steel plate drill ingahlukaniswa ibe yi-high-speed steel core drill (HSS) kanye ne-cemented carbide core drill (TCT) ngokusho kwempahla.
Isingeniso se-High Speed Steel Plate Drill(HSS core drill):
Insimbi enesivinini esiphezulu sesitimela sensimbi iyamukelwa, enochungechunge olubili lohlobo olujwayelekile kanye nohlobo olumanzi olomile;Ngezinhlobonhlobo zezinhlobo zokubamba, ijiyomethri yezinyo lokuphela elinelungelo lobunikazi, idizayini yokuhlukaniswa kwe-chip, ezinzile futhi enokwethenjelwa.
Ububanzi busukela ku-12mm kuye ku-36mm, kanti ukujula kungu-25mm no-50mm;
Isingeniso se-carbide steel plate drill(TCT core drill):
Uhlobo lwesibambo se-global brand drill lumbozwe ngokugcwele, futhi ububanzi bochungechunge olujwayelekile busuka ku-11mm ukuya ku-150mm.Ukujula kokusika kungu-35mm, 50mm, 75mm, 100mm, 150mm;
Ububanzi obukhulu bochungechunge olwenziwe ngezifiso ngu-200mm, futhi ukujula okuphezulu kokusika kungu-200mm;
Isebenzisa i-carbide blade enosimende ephuma kwamanye amazwe enezinhlayiya ezinhle kakhulu, eqinile, engagugi, futhi inokumelana nomthelela omuhle kakhulu.I-blade iboshwe ngokuqinile nesiqinisekiso sokuphila esizinzile;I-design ye-geometric blade enezingqimba ezintathu ibonisa ngokugcwele izici zamandla amancane okusika kanye ne-centering enhle;
Isingeniso sohlobo lwe-Hollow Drill Shank:
Ngenkathi ukhetha i-drill engenalutho enosayizi ofanele, uhlobo lwenduku kufanele lukhethwe ngokuya ngemodeli ye-drill kazibuthe.
Izinhlobo zesibambo ezijwayelekile zifaka izinhlobo eziyi-8: isibambo se-engeli engakwesokudla, isibambo esijwayelekile, isibambo sezimbobo ezine, isibambo sokusika esiyindilinga, isibambo esinentambo, isibambo se-engeli yesokudla sohlobo lwe-P, isibambo sezimbobo ezintathu, nesibambo sokusika esiyisicaba.
Isingeniso se-Twist Drill:
Ngaphezu kwalokho, ama-twist drill ajwayelekile nawo angabhoboza amapuleti ensimbi.
I-Twist drill iyithuluzi elisetshenziswa kakhulu emshinini womgodi.
Impahla yayo ngokuvamile iyinsimbi yamathuluzi esivinini esikhulu noma i-alloy eqinile.
Isetshenziselwa ikakhulukazi imishini yokumba, ama-lathes, imishini kagesi yezandla kanye nezinye izinto zokusebenza zemishini ukucubungula ububanzi obuhlukahlukene bembobo.
Ama-twist drills ngokuvamile ahlukaniswa abe ama-straight shank kanye nama-cone shank twist drill.
I-Shank drill eqondile: ifanele ukubhoboza imbobo encane ububanzi obungaphansi kuka-13.0mm, i-cone noma i-taper shank twist drill: ifanele izimbobo ezinobubanzi bembobo enkulu kanye ne-torque.
I-Twist drill iyithuluzi elisetshenziswa kakhulu lokwenza imbobo.Ngokuvamile, ububanzi busukela ku-0.25 kuya ku-80 mm.
Ikakhulukazi yakhiwe ingxenye yokusebenza nesibambo.Kunemifantu emibili evunguzayo engxenyeni yokusebenza, ebukeka njenge-twist, yingakho igama.
Ukuze kuncishiswe ukungqubuzana phakathi kwengxenye yomhlahlandlela kanye nodonga lwembobo ngesikhathi sokubhola, ububanzi be-twist drill buyancipha kancane kancane ukusuka endaweni yokubhoboza ukuya ku-shank, futhi busesimweni sekhoni ehlanekezelwe.I-engeli ye-helix ye-twist drill ithinta kakhulu usayizi we-engeli ye-rake onqenqemeni lokusika, amandla we-blade lobe kanye nokusebenza kokukhishwa kwe-chip, ngokuvamile okungu-25 ° ~ 32 °.I-Spiral groove ingagaywa futhi igaywe.
Ingxenye yangaphambili ye-drill bit igaywe ukuze yakhe ingxenye yokusika ngokugoqa okushisayo noma i-extrusion eshisayo.I-engeli ephezulu yengxenye yokusika ye-standard twist drill ingu-118, i-oblique angle ye-transverse edge ingu-40 ° ~ 60 °, kanti i-angle yangemuva ingu-8 ° ~ 20 °.
Ngenxa yezizathu zesakhiwo, i-engeli yangaphambili inkulu emaphethelweni angaphandle futhi iyancipha kancane kancane iye maphakathi.
Unqenqema lwesiphambano lune-engeli yangaphambili engalungile (kufika ku-55 °), esebenza njenge-extrusion ngesikhathi sokumba.Ukuze uthuthukise ukusebenza kokusika kwe-twist drill, ingxenye yokusika ingagaywa ibe yizimo ezihlukahlukene ngokuya ngezakhiwo zezinto ezicutshungulwayo (njengokubhola kweqembu).Ama-twist drill anezinhlobo ezimbili ze-shank: shank eqondile kanye ne-taper shank.Eyangaphambili iboshelwe ku-drill chuck kuyilapho eyakamuva ifakwa embotsheni ye-taper ye-spindle noma i-tailstock yethuluzi lomshini.
Ngokuvamile, ama-twist drill enziwa ngensimbi enesivinini esikhulu.Ama-twist drill ane-carbide efakwayo noma imiqhele afanele ukucubungula insimbi ecijile, insimbi eqinile kanye nezinto ezingezona ezensimbi.Izinsimbi ezincane ze-carbide ezihlanganisiwe zisetshenziselwa ukucubungula izingxenye zensimbi namabhodi wesekethe aphrintiwe.
Isingeniso se-Step Core Drill:
I-step core drill, eyaziwa nangokuthi i-step drill noma i-pagoda drill, isetshenziselwa kakhulu ukubhola amapuleti ensimbi amancane ngaphakathi kuka-3mm.
I-drill eyodwa ingasetshenziswa esikhundleni se-multiple drill.Izimbobo ezinobubanzi obuhlukene zingacutshungulwa njengoba kudingekile, futhi izimbobo ezinkulu zingacutshungulwa ngesikhathi esisodwa ngaphandle kokushintsha imbobo yokubhoboza nokubhola.
Ngokwesimo se-groove yomkhiqizo, ingahlukaniswa ibe yi-groove eqondile, i-spiral groove kanye ne-circular groove;
Njengamanje, yonke i-drill yesinyathelo ikhiqizwa yi-CBN yokugaya ngokugcwele, ikakhulukazi eyenziwe ngensimbi enesivinini esikhulu, i-alloy eqinile, njll., enezidingo zokunemba okuphezulu kokucubungula.Ngokwezimo ezihlukene zokucubungula, ukumbozwa kwendawo kungenziwa ukuze kunwetshwe impilo yamathuluzi futhi kuthuthukise ukuqina kwethuluzi.
Izivivinyo zethu zezinyathelo zenziwe ngensimbi eqinile kakhulu enesivinini esikhulu.
Ububanzi bomkhiqizo busukela ku-4mm kuye ku-40mm.
Inhlanganisela yezinyathelo isukela ezinyathelweni ezi-4 kuye kweziyi-13.
Kunezinhlobo ezimbili zama-grooves a-spiral kanye nama-grooves aqondile.
Ifanele ukubhoboza nokulungisa kabusha insimbi, insimbi eyinsimbi, insimbi engagqwali nezinye izinto;
Ukugaya ngokunemba ngemishini ezenzakalelayo;Inqubo yokumboza ingakhethwa.
Ngakho-ke, kubalulekile futhi ukukhetha i-drill bit enhle yokumba ipuleti lensimbi.
Kodwa ungakhathazeki.Uma unemibuzo, sicela ukhululeke ukuxhumana nathi.
Sihlale sikulungele ukukuphendulela noma yimiphi imibuzo.
Sineqembu lesevisi eliqeqeshiwe kanye nethimba lokukhiqiza.Kungakhathaliseki ukuthi u-oda usayizi ojwayelekile noma udinga ukwenza ngendlela oyifisayo, sizokunikeza ngohlu olugcwele lwezinsizakalo ezicabangelayo.
Siyakwamukela embuzweni wakho nganoma yisiphi isikhathi!
