Kwishishini lezixhobo,Iibhithi zokubhola ze-DIN338zihlala zibizwa ngokuba “ziindlela zokuqikelela ngokuchanekileyo”, ingakumbiIibhithi zokubhola ze-DIN338 HSSCO, ekuthiwa zenziwe ngentsimbi ekhawulezayo equlethe i-cobalt, zikwakhuthazwa njenge "sisombululo esiphezulu sokugrumba izinto eziqinileyo". Nangona kunjalo, kwizicelo zokwenyani zoshishino kunye nempendulo yabasebenzisi, ngaba ezi zixhobo zingcwele zingazizalisekisa izithembiso zazo? Masingene kwinyani engasemva kwemarike.
I. Umgangatho we-DIN338: Imida Phantsi Kwendawo Ebonakalayo
I-DIN338, njengomgangatho waseJamani wezoshishino kwiidrili ezijijekileyo ezithe tye, ngokwenene imisela iimfuno ezisisiseko zejometri, ukunyamezelana kunye nezinto ezisetyenziswa kwiidrili. Nangona kunjalo, "ukuhambelana ne-DIN338″ akuthethi ukuba "umgangatho ophezulu". Inani elikhulu leedrili ezingabizi kakhulu kwimarike zilinganisa nje inkangeleko kodwa azifikeleli kwiiparameter eziphambili:
- Ukubhalwa kwezinto ezingezizo kuxhaphakile: Abanye abavelisi babhala iibhithi zokubhola zentsimbi eqhelekileyo (i-HSS) ezikhawulezayo njenge-“HSSCO”, kodwa umxholo we-cobalt ungaphantsi kwe-5%, kude kakhulu nokufikelela kwimigangatho efunekayo yokucubungula izinto eziqinileyo.
- Iziphene kwinkqubo yokunyanga ubushushu: Ingxelo yomsebenzisi ibonisa ukuba ezinye iibhithi zokubhola ze-DIN338 zifakwa kwi-annealing ngaphambi kwexesha ngexesha lenkqubo yokubhola, kwaye kukwakho nokuqhekeka xa kusetyenzwa ngentsimbi engagqwaliyo.
- Ukungaguquguquki kakuhle kokuchaneka: Ukunyamezelana kobubanzi beebhithi zokubhola kwibhetshi enye kuyatshintshatshintsha kakhulu, nto leyo echaphazela kakhulu ukuchaneka kwendibano.
2. I-DIN338 HSSCO Drill Bit: "Intsomi Egqithisileyo Yokumelana Nobushushu"
Intsimbi ekhawulezayo ene-cobalt inokuphucula ubulukhuni obubomvu kunye nokumelana nokuguguleka kweebhithi zokubhola, kodwa ukusebenza kwayo kwenyani kuxhomekeke kakhulu kubunyulu bezinto ezikrwada kunye neenkqubo zonyango lobushushu. Uphando lufumanise ukuba:
- Ukukhuthazwa kobomi obuphantsi: Iziko lovavanyo lomntu wesithathu lithelekise iimpawu ezintlanu zeebhithi zokubhola ze-DIN338 HSSCO. Xa kuqhubeka kugqojozwa intsimbi engagqwaliyo engama-304, ziimpawu ezimbini kuphela ezazinobomi obungaphezulu kwemingxuma engama-50, ngelixa ezinye zonke zazinokonakala ngokukhawuleza.
- Ingxaki yokususwa kweetshiphusi: Ezinye iimveliso, ukuze kuncitshiswe iindleko, zinciphisa inkqubo yokupholisha umngxuma ojikelezayo, nto leyo ebangela ukuba iitshiphusi zinamathele kakhulu, nto leyo eyenza ukuba i-drill bit ibe nzima kakhulu kwaye imikrwelo ingasebenzi kakuhle.
- Imida yezinto ezifanelekileyo: Ibango elikwipromoshini lokuba "lisebenza kuzo zonke ii-alloys" lilahlekisa kakhulu. Kwizinto ezinobunzima obuphezulu (ezifana nee-alloys ze-titanium kunye nee-superalloys), ii-drill bits ze-DIN338 HSSCO ezikumgangatho ophantsi azikwazi ukususa iitships ngokufanelekileyo kwaye endaweni yoko zikhawulezise ukusilela.
3. Umsantsa wokwenyani phakathi kolawulo lomgangatho kunye neNkonzo yasemva kokuthengisa
Nangona abanye abavelisi besithi “banamaqela obuchwephesha aphambili” kunye “nenkonzo yamanye amazwe emva kokuthengisa”, izikhalazo zabasebenzisi zigxile kakhulu kwezi zinto zilandelayo:
- Iingxelo zovavanyo ezingekhoyo: Uninzi lwababoneleli abakwazi ukubonelela ngeengxelo zovavanyo lobunzima kunye nohlalutyo lwe-metallographic kwibhetshi nganye yeebhithi zokubhola.
- Impendulo ecothayo yenkxaso yobugcisa: Abasebenzisi bamanye amazwe baxele ukuba imibuzo malunga nokukhetha kunye nokusetyenziswa kwe-drill bit ayiphendulwa.
- Ukuphepha uxanduva emva kokuthengisa: Xa kukho iingxaki ngokuchaneka kokubhola, abavelisi badla ngokuzithiya ngenxa “yokusebenza okungafanelekanga” kwabasebenzisi okanye “ukungapholi ngokwaneleyo”.
4. Ukucamngca kweShishini: Ungawukhupha njani ngokwenene amandla okuchaneka?
Isatifikethi esisemgangathweni seenkcukacha
Umgangatho we-DIN338 kufuneka wohlule ngakumbi amanqanaba okusebenza (afana “nezinga lezimboni” kunye “nezinga lobungcali”), kwaye ngokunyanzelekileyo kufuneka uphawulwe iiparameter eziphambili ezifana nomxholo we-cobalt kunye nenkqubo yonyango lobushushu.
Abasebenzisi kufuneka baqaphele malunga nentetho yokuthengisa
Xa kuthengwa izinto, izigqibo akufuneki zenziwe ngokusekelwe kwigama elithi “DIN338 HSSCO” kuphela. Endaweni yoko, kufuneka kucelwe izatifikethi zezinto kunye nedatha yokulinganisa yokwenyani, kwaye ababoneleli ababonelela ngeepakeji zovavanyo kufuneka banikwe ingqalelo ephambili.
Isikhokelo sokuphuculwa kwetekhnoloji
Eli shishini kufuneka litshintshele kubuchwepheshe bokugquma (obufana nogquma lweTiAlN) kunye nophuhliso lwesakhiwo (obufana noyilo lwangaphakathi lwemingxunya yokupholisa), endaweni yokuxhomekeka kuphela ekulungisweni kakuhle kwezinto ezisetyenzisiweyo.
Isiphelo
Njengeemveliso zakudala kwicandelo lezixhobo, amandlaIibhithi zokubhola ze-DIN338kwayeIibhithi zokubhola ze-DIN338 HSSCOAkukho mathandabuzo. Nangona kunjalo, imakethi yangoku izaliswe ziimveliso zomgangatho owahlukileyo kunye neentengiso ezipakishwe ngokugqithisileyo, nto leyo enciphisa ukuthembeka kwalo mgangatho. Kwabo basebenza ngengqondo, kuphela ngokungena kwinkungu yokuthengisa nokusebenzisa idatha yokulinganisa yokwenyani njengomlinganiselo apho banokufumana khona izisombululo zokubhola ezinokuthenjwa ngokwenene - emva kwayo yonke loo nto, ukuchaneka akuze kufezekiswe ngelebheli enye.
