Zenziwa kanjani izingcezu zokubhoboza? Yiziphi izinkinga okuzohlangatshezwana nazo ekucubungulweni kokubhola? Mayelana ne-drill material kanye nezakhiwo zayo? Wenzani uma i-drill yakho ihluleka?
Njengethuluzi elivame kakhulu ekushicileleni izimbobo, izinsimbi zokubhoboza zisetshenziswa kakhulu ekwenziweni kwemishini, ikakhulukazi ekwenzeni izimbobo ezingxenyeni ezifana nemishini yokupholisa, amashidi eshubhu wezinto zokuphehla amandla, kanye namajeneretha esitimu. Isicelo sibanzi futhi sibalulekile. Namuhla, uProfesa Wobunjiniyela Bemishini uthole leli qoqo le-drill bit yawo wonke umuntu kuplathifomu ye-WeChat. Konke okudingayo kulapha!
Izici Zokubhoboza
Ama-drill ngokuvamile anemiphetho emibili yokusika. Ngesikhathi sokusebenza, i-drill iyasikwa ngenkathi ijikeleza. I-engeli ye-rake ye-drill bit ikhuphuka ukusuka eksisi emaphakathi ukuya onqenqemeni lwangaphandle. Ijubane lokusika le-drill bit liyakhula njengoba lisondela kumbuthano wangaphandle, futhi isivinini sokusika siyehla sibheke phakathi nendawo. Isivinini sokusika sesikhungo sokujikeleza se-drill bit nguziro. I-chisel edge ye-drill bit itholakala eduze kwe-axis yesikhungo sokujikeleza, i-chisel edge ine-angle enkulu ye-rake eyi-axiliary, ayikho indawo ye-chip, futhi isivinini sokusika siphansi, esizokhiqiza ukumelana okukhulu kwe-axial. Uma i-chisel edge iphansi ukuze uthayiphe u-A noma uthayiphe C ku-DIN1414, futhi umkhawulo wokusika eduze kwe-axis ephakathi une-angle ye-rake enhle, ukumelana nokusika kungancishiswa futhi ukusebenza kokusika kungathuthukiswa kakhulu.
Ngokuvumelana nobujamo obuhlukene bomsebenzi wokusebenza, izinto zokwakha, imisebenzi, njll., ukubhola kungahlukaniswa ngezinhlobo eziningi, njengezinsimbi zensimbi ezinesivinini esikhulu (ama-twist drill, ama-group drill, ama-flat drill), imishini yokubhoboza i-carbide eqinile, izimbobo zemigodi ezingashoni, ezingashoni, ukubhoboza imigodi ejulile, njll. Ukubhoboza, ukubhoboza ama-trepanning nama-drill ekhanda ashintshwayo, njll.
1. Ukucubungula/ukucutshungulwa
1.1 Inqubo
❶ Ngokuhambisana nobubanzi nobude obuphelele bebhithi yokubhola eklanyelwe, ungakhetha umshini wokusika ibha yengxubevange noma usebenzise okokusika ngocingo ukuze kucutshungulwe ubude obungaguquki.
❷ Kubha yokusika yobude obugxilile, iziphetho ezimbili zebha zineziphetho eziyisicaba, ezingenziwa ngomshini wokugaya ithuluzi owenziwe ngesandla.
❸ Ukubhoboza noma ukubhoboza ubuso bokugcina be-alloy bar obugayiwe, kulungiselelwa ukugaya i-diameter yangaphandle kanye ne-shank ye-drill bit, kuye ngokuthi into eyicylindrical yokugaya iyithiphu yowesilisa noma ithiphu yowesifazane.
❹ Emshinini wokugaya onembe kakhulu oyisilinda, ububanzi obungaphandle bebhithi yokubhoboza, ingxenye engenalutho kanye nobubanzi obungaphandle be-shank kuyacutshungulwa ukuze kuqinisekiswe izidingo zokuklama ezifana ne-diameter cylindricity, ukuphuma okuyindilinga, nokuqedwa kwendawo.
❺ Ukuze kuthuthukiswe ukusebenza kahle kokucubungula emshinini wokugaya we-CNC, ngaphambi kokuba ibha yengxubevange ifakwe emshinini wokugaya we-CNC, ingxenye yethiphu yokubhoboza ingashintshwa, isibonelo, i-angle yokubhoboza i-140 °, futhi i-chamfer ingaba cishe phansi ku-142 °.
❻ Ngemuva kokuthi ibha ye-alloy e-chamfered ihlanjululwe, idluliselwa kwinqubo yomshini wokugaya we-CNC, futhi ingxenye ngayinye ye-drill bit icutshungulwa emshinini wokugaya we-CNC we-axis emihlanu.
❼ Uma kudingekile ukuthuthukisa umtshingo wensimbi yokubhoboza kanye nokushelela kwendilinga yangaphandle, ingagaywa futhi ipholishwe ngamasondo oboya nama-abrasive ngaphambi noma ngemva kwesinyathelo sesihlanu. Yiqiniso, kulokhu, i-drill bit idinga ukucutshungulwa ngezinyathelo eziningi.
❽ Ezingxenyeni zokuzibhoboza esezicubunguliwe futhi zafaneleka, zizomakwa nge-laser, futhi okuqukethwe kungase kube i-LOGO yenkampani nosayizi womshini kanye nolunye ulwazi.
❾ Pakisha izingcezu zokubhoboza ezimakiwe bese uzithumela enkampanini yokugqoka yamathuluzi echwepheshile ukuze zihlanganiswe.
1. Uma umtshingo we-drill bit uvuliwe, noma umtshingo ovunguzayo noma oqondile, lesi sinyathelo sihlanganisa nokukhala okungalungile konqenqema lwe-peripheral; bese ucubungula umkhawulo wokusika wephoyinti lokubhoboza, kufaka phakathi ingxenye ye-backlash yephoyinti lokubhoboza kanye nekhona elingemuva lephoyinti lokubhoboza; bese uqhubeka Ingxenye engemuva ye-peripheral edge ye-drill bit iyacutshungulwa, futhi inani elithile lokudonsa liphansi ukuze kuqinisekiswe ukuthi ingxenye yobubanzi yangaphandle yonqenqema lwe-peripheral of the drill bit kanye nendawo yokuxhumana yodonga lwembobo yokusebenza iyalawulwa. ngesilinganiso esithile.
2. Ukuze kucutshungulwe i-chamfer engalungile ye-drill tip edge, ihlukaniswe ngomshini wokugaya we-CNC noma ukucubungula okwenziwa ngesandla, okuhlukile ngenxa yezinqubo ezahlukene zemboni ngayinye.
1.2 Ukucubungula izindaba
❶ Lapho ucubungula ingxenye yendilinga yangaphandle yokubhoboza emshinini wokugaya oyicylindrical, kubalulekile ukunaka ukuthi into ayilungile yini nokuthi upholise ngokugcwele ibha yengxubevange ngesikhathi sokucubungula, kanye nokugcina umkhuba omuhle wokukala ububanzi bangaphandle be-alloy bar. i-drill tip.
❷ Lapho ucubungula ama-drill emishinini yokugaya ye-CNC, zama ukuhlukanisa ukucutshungulwa okuqinile nokucolile kube izinyathelo ezimbili lapho uhlela, ukuze ugweme imifantu engase ibe khona eshisayo ebangelwa ukugaya kakhulu, okuzothinta impilo yesevisi yethuluzi.
❸ Sebenzisa ithreyi lempahla eklanywe kahle ukuze ubambe imimese ukuze ugweme ukulimala onqenqemeni oludalwe ukungqubuzana kwemibese.
❹ Ngesondo lokugaya idayimane eliye laba mnyama ngemva kokugaya, sebenzisa itshe likawoyela ukuze ulole unqenqema ngokuhamba kwesikhathi.
Qaphela: Ngokwezinto ezicutshunguliwe/izinto zokusebenza/izimo zokusebenza, ubuchwepheshe bokucubungula abufani. Ukuhlelwa kwenqubo okungenhla kumelela umbono womuntu siqu wombhali kuphela futhi kungokuxhumana kwezobuchwepheshe kuphela.
2. Dweba izinto
2.1 Insimbi enesivinini esikhulu
I-High-speed steel (HSS) iyinsimbi yethuluzi enobulukhuni obuphezulu, ukumelana nokugqokwa okuphezulu nokumelana nokushisa okuphezulu, eyaziwa nangokuthi insimbi yamathuluzi esivinini esikhulu noma insimbi yangaphambili, eyaziwa kakhulu ngensimbi emhlophe.
I-High-speed steel cutter iwuhlobo lokusika oluqinile futhi olulula ukusisika kunabasiki abavamile. Insimbi enesivinini esikhulu inokuqina okungcono, amandla nokumelana nokushisa kunensimbi yethuluzi le-carbon, futhi isivinini sayo sokusika singaphezu kwensimbi yensimbi ye-carbon (ingxube ye-iron-carbon). Ziningi, ngakho ibizwa ngensimbi enesivinini esikhulu; futhi i-carbide enosimende inokusebenza okungcono kunensimbi enesivinini esikhulu, futhi isivinini sokusika singanyuswa izikhathi ezingu-2-3.
Izici: Ubulukhuni obubomvu bensimbi enesivinini esiphezulu bungafinyelela kuma-degree angu-650. Insimbi enesivinini esikhulu inamandla amahle kanye nokuqina. Ngemuva kokucija, umkhawulo wokusika ubukhali futhi ikhwalithi izinzile. Ngokuvamile isetshenziselwa ukwenza imimese emincane futhi eyinkimbinkimbi.
2.2 I-Carbide
Izingxenye eziyinhloko ze-cemented carbide drill bits yi-tungsten carbide ne-cobalt, ehlanganisa amaphesenti angu-99 azo zonke izingxenye, futhi i-1% ingenye izinsimbi, ngakho ibizwa ngokuthi i-tungsten carbide (i-tungsten carbide). I-Tungsten carbide yakhiwe okungenani ngensimbi eyodwa ye-carbide Sintered composite materials. I-Tungsten carbide, i-cobalt carbide, i-niobium carbide, i-titanium carbide, ne-tantalum carbide yizingxenye ezivamile zensimbi ye-tungsten. Usayizi wokusanhlamvu wengxenye ye-carbide (noma isigaba) ngokuvamile uphakathi kwama-microns angu-0.2-10, futhi izinhlamvu ze-carbide zibanjwe ndawonye zisebenzisa i-binder yensimbi. Izinsimbi zokuhlanganisa ngokuvamile ziyizinsimbi zeqembu lensimbi, ezivame ukusetshenziswa yi-cobalt ne-nickel. Ngakho-ke, kukhona ama-alloys e-tungsten-cobalt, ama-tungsten-nickel alloys nama-tungsten-titanium-cobalt alloys. I-sintering molding ye-tungsten steel drill bit material ukucindezela impushana ibe yi-billet, bese uyishisisa ezingeni lokushisa elithile (izinga lokushisa le-sintering) esithandweni somlilo, uyigcine isikhathi esithile (isikhathi sokubamba), bese uyipholisa phansi. ukuthola impahla yensimbi ye-tungsten enezakhiwo ezidingekayo.
Izici:
Ubulukhuni obubomvu be-carbide enosimende bungafinyelela ku-800-1000 degrees.
Ijubane lokusika le-carbide enosimende liphakeme izikhathi ezi-4-7 kunelensimbi enesivinini esikhulu. High ukusika ukusebenza kahle.
Okubi amandla okugoba aphansi, ukuqina komthelela ongemuhle, ukonakala okuphezulu, nomthelela ophansi kanye nokumelana nokudlidliza.
