Zenziwa njani iintwana zokomba? Zeziphi iingxaki ekuza kuhlangatyezwana nazo xa kusetyenzwa? Malunga nezinto zokuqhuba kunye neempawu zayo? Wenza ntoni xa i-drill yakho ingaphumeleli?
Njengesona sixhobo sixhaphakileyo kumatshini wokwenza imingxunya, amasuntswana okomba asetyenziswa kakhulu kwimveliso yoomatshini, ngakumbi ukwenziwa kwemingxuma kwiindawo ezifana nezixhobo zokupholisa, amaphepha etyhubhu ezixhobo zokuvelisa amandla, kunye neejenereyitha zomphunga. Isicelo sibanzi kwaye sibalulekile. Namhlanje, uNjingalwazi wezobuNjineli booMatshini ufumene le ngqokelela yentwana ye-drill kuye wonke umntu okwiqonga le-WeChat. Yonke into oyifunayo ilapha!
Drilling Iimpawu
I-Drills idla ngokuba nemiphetho emibini yokusika. Ngexesha lokucoca, i-drill cuts ngelixa ijikeleza. I-rake angle ye-drill bit inyuka ukusuka kwi-axis esembindini ukuya kumda wangaphandle. Isantya sokusika i-drill bit sinyuka njengoko sisondela kwisangqa sangaphandle, kwaye isantya sokusika siyancipha ukuya kwiziko. Isantya sokusika se-drill bit's rotation center ngu-zero. I-chisel edge ye-drill bit ifumaneka kufuphi ne-axis yeziko lokujikeleza, i-chisel edge ine-angle ye-rake encedisayo enkulu, akukho ndawo ye-chip, kunye nesantya sokusika siphantsi, esiza kuvelisa ukuchasana kwe-axial enkulu. Ukuba umgca we-chisel uphantsi ukuze uthayiphe i-A okanye uthayiphe i-C kwi-DIN1414, kwaye umgca wokusika kufuphi ne-axis ephakathi une-angle ye-rake e-positive, ukuchasana kokusika kunokunciphisa kwaye ukusebenza kokusika kunokuphuculwa kakhulu.
Ngokwemilo eyahlukeneyo yokusebenza, izixhobo, izakhiwo, imisebenzi, njl., iidrill zinokwahlulwa zibe ziindidi ezininzi, ezifana ne-high-speed steel drills (i-twist drills, i-drill drills, i-flat drills), i-drills eqinile ye-carbide, i-indexable drills i-hole drills, imingxunya enzulu drills, etc. Drills, trepanning drills kunye replaceable intloko drill, njl.
1. Inkqubo / inkqubo
1.1 Inkqubo
❶ Ngokobubanzi kunye nobude obupheleleyo be-drill bit eyiliweyo, ungakhetha umatshini wokusika ibha yealloyi okanye usebenzise izixhobo zokusika ucingo ukusetyenzwa kobude obusisigxina.
❷ Kwibha yokusika yobude obusisigxina, iziphelo ezimbini zebar ziphelile, ezinokuqondwa kwisixhobo sokugaya izixhobo.
❸ Ukubetha okanye ukugrumba ubuso besiphelo se-alloy bar egayiweyo, ukulungiselela ukucola i-diameter yangaphandle kunye neshank ye-drill bit, kuxhomekeke ekubeni isitshixo sokusila yincam yendoda okanye incam yabasetyhini.
❹ Kumatshini wokusila we-cylindrical ochanekileyo ophezulu, i-diameter yangaphandle ye-drill bit, indawo evulekileyo kunye nobubanzi obungaphandle be-shank iyacutshungulwa ukuze kuqinisekiswe iimfuno zoyilo ezifana ne-cylindricity yangaphandle ye-diameter, i-circular runout, kunye nokugqiba umphezulu.
❺ Ukuze kuphuculwe ukusebenza kakuhle kumatshini wokugaya we-CNC, ngaphambi kokuba ibha ye-alloy ibekwe kumatshini wokusila we-CNC, inxalenye yencam ye-drill inokuthi ihlanjululwe, umzekelo, i-angle ye-drill tip yi-140 °, kwaye i-chamfer ingaba phantsi ngokurhabaxa ukuya kwi-142°.
❻ Emva kokuba i-alloy bar ye-chamfered ihlanjululwe, idluliselwa kwinkqubo yomshini wokugaya i-CNC, kwaye inxalenye nganye ye-drill bit icutshungulwa kumatshini wokugaya we-CNC we-five-axis.
❼ Ukuba ngaba kukho imfuneko yokuphucula iflute ye-drill bit kunye nokuguda kwesangqa sangaphandle, inokucolwa kwaye ikhazimliswe ngamavili oboya kunye neziqhushumbisi phambi okanye emva kwenyathelo lesihlanu. Ngokuqinisekileyo, kule meko, i-drill bit kufuneka iqhutywe ngamanyathelo amaninzi.
❽ Ukulungiselela amasuntswana e-drill asele elungisiwe, aya kumakishwa nge-laser, kwaye umxholo usenokuba yi-logo yenkampani kunye nobukhulu bomatshini kunye nolunye ulwazi.
❾ Pakisha amasuntswana e-drill aphawulweyo kwaye uwathumele kwinkampani yobuchwephesha bokugquma izixhobo zokugquma.
1. Ukuba i-flute ye-drill bit ivuliwe, okanye i-spiral okanye i-flute ethe nkqo, eli nyathelo likwabandakanya i-chamfering embi ye-edge ye-peripheral; emva koko uqhube umgca wokusika we-drill point, kubandakanywa nenxalenye ye-backlash ye-drill point kunye nekona yangasemva ye-drill point; emva koko uqhubeke Inxalenye yangasemva yomngcele we-peripheral ye-drill bit icutshungulwa, kwaye umlinganiselo othile wokulahla uphantsi ukuqinisekisa ukuba inxalenye engaphandle yedayamitha yecala le-peripheral ye-drill bit kunye nomphezulu woqhagamshelwano wodonga lomngxuma wokusebenza luyalawulwa. ngokomlinganiselo othile.
2. Ukucutshungulwa kwe-chamfer engathandekiyo ye-drill tip edge, ihlulwe ibe yi-CNC yokusila umatshini wokugaya okanye i-manual processing, eyahlukileyo ngenxa yeenkqubo ezahlukeneyo zefektri nganye.
1.2 Ukuqwalaselwa kwemiba
❶ Xa kusetyenzwa inxalenye yesangqa sangaphandle se-drill kumatshini wokusila oyicylindrical, kuyafuneka ukuba unike ingqwalaselo ukuba ingaba isitshixo asisebenzi kwaye ukupholisa ngokupheleleyo ibha yealloyi ngexesha lokusetyenzwa, kunye nokugcina umkhwa olungileyo wokulinganisa i-diameter yangaphandle ye-alloy bar. i-drill tip.
❷ Xa ucubungula i-drills kumatshini wokugaya i-CNC, zama ukwahlula ukucokiseka kunye nokusebenza kakuhle kumanyathelo amabini xa ucwangciswa, ukwenzela ukuba ugweme ukuqhekeka okunokwenzeka kwe-thermal okubangelwa ukugaya kakhulu, okuya kuchaphazela ubomi benkonzo yesixhobo.
❸ Sebenzisa i-tray yempahla eyenziwe kakuhle yokuphatha iimela ukuphepha umonakalo kwi-edge yokusika okubangelwa ukungqubana kweemela.
❹ Kwivili lokusila idayimani eliye laba mnyama emva kokusila, sebenzisa ilitye le-oyile ukulola incam kwangethuba.
Qaphela: Ngokwezinto ezisetyenzisiweyo / izixhobo / iimeko zokusebenza, iteknoloji yokucubungula ayifani. Olu lungiselelo lwenkqubo olungentla lubonisa kuphela uluvo lombhali lobuqu kwaye lunxibelelwano lobugcisa kuphela.
2. Drill imathiriyeli
2.1 Isantya esiphezulu sentsimbi
Intsimbi yesantya esiphezulu (i-HSS) sisixhobo sensimbi enobunzima obuphezulu, ukuxhathisa ukunxiba okuphezulu kunye nokumelana nobushushu obuphezulu, okwaziwa ngokuba yintsimbi yesixhobo esinesantya esiphezulu okanye intsimbi yangaphambili, eyaziwa ngokuba yintsimbi emhlophe.
I-high-speed steel cutter luhlobo lwe-cutter oluqina kwaye kulula ukusika kune-cutters eziqhelekileyo. I-Speed-speed steel inobunzima obungcono, amandla kunye nokumelana nokushisa kune-carbon tool steel, kwaye isantya sayo sokusika siphezulu kune-carbon tool steel (i-iron-carbon alloy). Zininzi, ngoko kuthiwa yintsimbi enesantya esiphezulu; kunye ne-carbide ene-cemented inomsebenzi ongcono kune-high-speed steel, kwaye isantya sokusika sinokunyuswa ngamaxesha angama-2-3.
Iimpawu: Ubunzima obubomvu bentsimbi yesantya esiphezulu bunokufikelela kwi-650 degrees. Intsimbi enesantya esiphezulu inamandla amahle kunye nokuqina. Emva kokulola, umgca wokusika ubukhali kwaye umgangatho uzinzile. Ngokuqhelekileyo isetyenziselwa ukwenza iimela ezincinci nezintsonkothileyo.
2.2 Carbide
Amacandelo aphambili e-cemented carbide drill bits yi-tungsten carbide kunye ne-cobalt, eyenza i-99% yazo zonke izinto, kunye ne-1% yezinye isinyithi, ngoko kuthiwa yi-tungsten carbide (tungsten carbide). I-tungsten carbide yenziwe ubuncinane enye yentsimbi ye-carbide Sintered composite materials. I-tungsten carbide, i-cobalt carbide, i-niobium carbide, i-titanium carbide, kunye ne-tantalum carbide zizinto eziqhelekileyo zentsimbi ye-tungsten. Ubungakanani obuziinkozo becandelo le-carbide (okanye isigaba) ngokuqhelekileyo phakathi kwe-0.2-10 microns, kunye neengqolowa ze-carbide zibanjwe kunye zisebenzisa i-binder yensimbi. Iintsimbi zokubopha zidla ngokuba ziintsimbi zeqela lentsimbi, ezidla ngokusetyenziswa yicobalt kunye nenickel. Ngoko ke, kukho i-tungsten-cobalt alloys, i-tungsten-nickel alloys kunye ne-tungsten-titanium-cobalt alloys. Ukubunjwa kwe-sintering ye-tungsten metal drill bit material kukucinezela umgubo kwi-billet, emva koko uyifudumeze kubushushu obuthile (ubushushu be-sintering) kwisithando somlilo, uyigcine ixesha elithile (ukubamba ixesha), kwaye emva koko uyipholise. ukufumana impahla yensimbi ye-tungsten eneempawu ezifunekayo.
Iimbonakalo:
Ubunzima obubomvu be-carbide ene-cemented bungafikelela kwi-800-1000 degrees.
Isantya sokusika i-carbide ene-cemented ngamaxesha angama-4-7 aphezulu kuneyentsimbi ephezulu. Ukusebenza kakuhle kokusika.
Izinto ezingeloncedo ngamandla okugoba aphantsi, ukuqina kwefuthe elibi, ubuqhophololo obuphezulu, kunye nefuthe eliphantsi kunye nokumelana nokungcangcazela.
