Kuyini ukubhola?
Indlela yokubhoboza imbobo?
Indlela yokwenza ukubhola kunembe kakhudlwana?
Kuchazwe ngokucacile ngezansi, ake sibheke.
1. Imiqondo eyisisekelo yokumba
Ngokuvamile, ukubhola kubhekisela endleleni yokucubungula esebenzisa i-drill ukucubungula izimbobo endaweni yomkhiqizo. Ngokuvamile, lapho umba imikhiqizo emshinini wokubhoboza, i-drill bit kufanele iqedele ukunyakaza okubili ngasikhathi sinye:
① Ukunyakaza okuyinhloko, okungukuthi, ukunyakaza okujikelezayo kwe-drill bit ezungeze i-eksisi (ukunyakaza kokusika);
②Ukunyakaza kwesibili, okungukuthi, ukunyakaza okuqondile kwe-drill bit eduze kwe-eksisi ukuya endaweni yokusebenza (ukunyakaza kokuphakelayo).
Lapho ubhoboza, ngenxa yokushiyeka esakhiweni se-drill bit, amamaki azoshiywa ezingxenyeni ezicutshunguliwe zomkhiqizo, ezithinta ikhwalithi yokucubungula ye-workpiece. Ukunemba kokucubungula kuvame ukuba ngaphansi kwezinga le-IT10, futhi ubulukhuni obungaphezulu bucishe bube ngu-Ra12.5μm, okuyingxenye yesigaba somshini onzima. .
2. Inqubo yokusebenza yokumba
1. Ukumaka: Ngaphambi kokubhoboza, qala uqonde izidingo zomdwebo. Ngokwezidingo eziyisisekelo ezijwayelekile zokubhoboza, sebenzisa amathuluzi ukumaka umugqa ophakathi nendawo wembobo. Umugqa omaphakathi kufanele ucace futhi unembile, futhi omncane ube ngcono. Ngemuva kokudweba umugqa, Linganisa ngama-calipers e-vernier noma irula yensimbi.
2. Dweba isikwele sokuhlola noma indilinga yokuhlola: Ngemva kokudweba umugqa nokudlulisa ukuhlolwa, isikwele sokuhlola noma indilinga yokuhlola enomugqa omaphakathi womgodi njengesikhungo sokulinganisa kufanele zidwetshwe njengomugqa wokuhlola ngesikhathi sokumba ukuze kube lula ukuhlola. ngesikhathi sokumba. kanye nokuma kokumba okulungile.
3. Ukuqinisekisa nokushaya isibhakela: Ngemva kokudweba isikwele sokuhlola esihambisanayo noma indilinga yokuhlola, ukuqinisekisa nokushaya ngesibhakela kufanele kwenziwe ngokucophelela. Okokuqala yenza iphuzu elincane, futhi ulinganise izikhathi eziningana ngezindlela ezihlukene zomugqa ophakathi nendawo ukuze ubone ukuthi imbobo yesibhakela ibhontshiwe ngempela yini ezimpambanweni zomugqa wesikhungo esiphambanayo, bese ushaya isampula ngendlela eqondile, eyindilinga, futhi ebanzi. ngokubeka okunembile. Ummese uphakathi nendawo.
4. Ukugoqa: Sebenzisa iragi ukuhlanza ithebula lomshini, indawo engaphezulu, kanye nendawo yokusebenza yedatum, bese ucindezela ucezu lokusebenza. I-clamping kufanele ishelele futhi ithembeke njengoba kudingeka, futhi ilungele ukuphenywa nokukalwa nganoma yisiphi isikhathi. Kudingekile ukuthi unake indlela yokuqinisa i-workpiece ukuvimbela ucezu lokusebenzela ukuthi lungakhubazeki ngenxa ye-clamping.
5. Ukuhlola ukubhoboza: Ukuhlola umgodi kufanele kwenziwe ngaphambi kokumba okusemthethweni: qondanisa unqenqema lweshizolo lwebhithi yokubhoboza nendawo emaphakathi yembobo bese ubhoboza umgodi ongashoni, bese uhlola ngokubukeka ukuthi ngabe isiqondiso somgodi ongashoni silungile yini. Kuyadingeka futhi ukulungisa njalo ukuphambuka ukwenza umgodi ongashoni kanye nesiyingi sokuhlola i-Coaxial. Uma ukuchezuka kukuncane, i-workpiece ingaphushwa ngokuphambene nokuchezuka ngenkathi ubhoboza ukuze kuzuzwe ukulungiswa kancane kancane.
6. Ukumba: Ukumba ngomshini ngokuvamile kusekelwe ekusebenzeni kokuphakelayo mathupha. Lapho ukunemba kwesimo sokuhlola kuyadingeka, ukumba kungenziwa. Lapho uncelisa ngesandla, amandla okuphakela akufanele abangele ukuthi i-drill bit igobe ukuvimbela i-axis yembobo ukuthi ingatsheki.
3. Izindlela zokunemba okuphezulu kokumba
1. Ukulola i-drill bit kuyisiqalo sayo yonke into
I-drill bit ehambisanayo kufanele ikhethelwe ukulola ngaphambi kokubhola. Ngaphezu kokuqinisekisa i-engeli ye-vertex enembile, i-clearance angle, kanye ne-chisel edge bevel, i-drill bit ecijile inobude obufanayo bemiphetho emibili eyinhloko futhi iyalingana nomugqa omaphakathi we-drill bit, futhi izindawo ezimbili eziyinhloko ze-flank zibushelelezi. , ukuze kube lula ukugxilisa i-centering futhi kunciphise ukuqina kodonga lwembobo. , i-chisel edge kanye ne-main cutting edge kufanele futhi igaywe kahle (kungcono ukugaya okunamandla ku-grinder kuqala, bese ugaya kahle etsheni lamafutha).

2. Umdwebo womugqa onembile uyisisekelo
Uma usebenzisa igeji yobude ukumaka imigqa ngokunembile, okokuqala, kufanele uqinisekise ukuthi ukuqondanisa kunembile. Uma umaka, qiniseka ukuthi i-angle phakathi kwe-engeli yenaliti kanye nendiza yokumaka ye-workpiece ingama-degrees angu-40 kuya kwangu-60 (ngokuhambisana nesiqondiso sokumaka), ukuze imigqa edwetshiwe icace futhi ilingane. Naka ukukhethwa kwendiza ye-datum ebhalayo. Indiza ye-datum kufanele icutshungulwe ngokunembile futhi ukucaba kwayo kanye ne-perpendicularity ezindaweni eziseduze kufanele kuqinisekiswe. Ngemuva kokuthi umugqa wesiphambano wesikhundla sembobo udwetshiwe, ukuze uqinisekise ukuqondanisa okulula lapho ubhoboza, sebenzisa i-punch ephakathi ukuze ukhiphe iphuzu eliphakathi emgqeni wesiphambano (iphuzu le-punch kumele libe lincane futhi isiqondiso kufanele sinembile).
3. Ukubopha okulungile kuyisihluthulelo
Imvamisa, ezimbobeni ezinobubanzi obungaphansi kuka-6 mm, uma ukunemba kungaphakeme, ungasebenzisa amapulangwe esandla ukuze ubambe umsebenzi wokubhoboza; emigodini ephakathi kuka-6 no-10 mm, uma i-workpiece ivamile futhi iyisicaba, ungasebenzisa ama-pliers flat-nose, kodwa i-workpiece kufanele ibe I-surface i-perpendicular ku-spindle yomshini wokumba. Uma ubhoboza imbobo enobubanzi obukhulu, i-flat-nose pliers kumele ilungiswe ngepuleti yokucindezela ye-bolt; kuma-workpieces amakhulu anobubanzi bokubhola obungaphezu kuka-10 mm, sebenzisa indlela yokugoqa ipuleti lokucindezela ukuze ubhoboze.
4. Ukuthola ukhiye ngokunembile kuyisihluthulelo
Ngemuva kokuthi i-workpiece iboshwe, ungajahi ukulahla i-drill. Ukuqondanisa kufanele kwenziwe kuqala. Ukuqondanisa kuhlanganisa ukuqondanisa okumile kanye nokuqondanisa okuguquguqukayo. Okubizwa ngokuthi ukulungiswa kwe-static kubhekisela ekuqondaneni ngaphambi kokuba umshini wokumba uqalwe, ukuze umugqa ophakathi we-spindle yomshini wokubhoboza kanye nokuphambana kwe-workpiece cross line kuqondiswe. Le ndlela iphephile futhi ilungele abaqalayo futhi kulula ukuyiqonda. Kodwa-ke, akunaki ukujika kwe-spindle yomshini wokumba, isibonelo. nezinye izici ezingaqinisekile, ukunemba kokumba kuphansi. Ukuqondanisa okunamandla kwenziwa ngemva kokuba umshini wokumba uqalisiwe. Ngesikhathi sokuqondisa, ezinye izici ezingaqinisekile ziyacatshangelwa, futhi ukunemba kuphakeme kakhulu.
5. Ukuhlola ngokucophelela kubalulekile
Ukuhlola kungathola ngokunembile nangesikhathi esifanele ukunemba komgodi ukuze kuthathwe izinyathelo ezidingekayo ukuze kunxeshezelwe. Emigodini enokunemba okuphezulu kokumba, ngokuvamile sisebenzisa amasu okucubungula, ukuphinda futhi asebenze kabusha. Ngemva kokubhoboza imbobo encane esinyathelweni sokuqala, sebenzisa i-caliper ukuthola iphutha ukusuka maphakathi nembobo engezansi kuya kudathamu. Ngemva kokulinganisa kwangempela, bala indawo yembobo engezansi kanye nendawo ekahle. Uma iphutha lingelikhulu kuno-0.10mm, ungakwazi ukunweba imbobo. Khulisa ngokufanelekile i-engeli yethiphu yokubhoboza, wenze buthaka umphumela wokugxilisa othomathikhi, usunduze kahle isiqeshana sokusebenza siye ohlangothini oluhle, bese ukhuphula kancane kancane ububanzi bethiphu yokubhoboza ukuze unxephezele. Uma iphutha likhulu kuno-0.10mm, ifayela eliyindilinga elihlukahlukene lingasetshenziswa ukunquma izindonga eziseceleni zembobo engezansi. Ingxenye enqunyiwe kufanele ixhunywe ne-arc yembobo engezansi ekushintsheni okubushelelezi.
