Iyo wunvise 'Alloy 1' muri ubu bucuruzi, igisubizo cya mbere akenshi ni ugusezerera. Ntabwo ari izina ryiza rya superalloy, kandi uwo ni umutego wambere. Abantu bakeka ko ari rusange, igiciro gito cyakazi, birashoboka ko byoroshye ibyuma bya karubone. Icyo gitekerezo cyatwaye umushinga urenze umwe mubijyanye n'imikorere, mvugishije ukuri, amafaranga. Mumyaka mirongo itatu namaze hafi yimishinga n'amaduka yimashini, nabonye 'Alloy 1' yerekanwe kubishushanyo aho injeniyeri yari akeneye gusa 'ubwoko bwibyuma,' kandi nabonye ko ari amahitamo akomeye, adashobora kuganirwaho kubice byananiranye mubindi byose. Ukuri ni, 'Alloy 1' ntabwo ari ikintu kimwe. Ni icyiciro, aho gitangirira, kandi imyitwarire yacyo igenwa rwose nubushyuhe bwihariye bwo kuvura ubushyuhe, uburyo bwo guta, hamwe nogukora nyuma. Kubona neza ni bike kubijyanye nicyemezo cyibikoresho nibindi byinshi bijyanye numurongo wose wuburinzi kuva gushonga kugeza birangiye.
Igorofa Igorofa
Reka tuvuge kubyerekeranye. Muri shell mold casting, dukoresha cyane mubigo byacu, Amavuta 1 Yerekana ikibazo kidasanzwe mumazi no kugabanuka. Ntabwo ariruka nkibintu bimwe byumuhondo, kuburyo sisitemu yo gutambuka iba iyambere. Ndibuka icyiciro cyamazu ya pompe, yenda ibice 500, aho twakoresheje imiterere isanzwe yo kwinjirira kuva mubice bisa nkibice byicyuma. Igisubizo cyabaye ugukomeza kugabanuka muburyo bukabije bwo kuzamuka. Amavuta yavanze gusa muburyo butandukanye. Tugomba gusubira inyuma, kongera ubunini bwa riser, no guhindura ubushyuhe bwo gusuka kuri 25 ° C. Ibyo byakosowe. Nibintu byahinduwe bitandukanya gutandukanya gukoreshwa gukoreshwa. Abasore kuri Ikoranabuhanga rya Qingdao Qiangsenyuan (QSY) ibi wabibonye inshuro igihumbi - imyaka mirongo itatu muri casting bivuze ko wubatse isomero ryibi bikosorwa bito kuri geometrie itandukanye.
Gutera ishoramari nindi nkuru. Hano, hamwe Amavuta 1, hejuru yubuso nibyiza, ariko ikiguzi cyibumba ceramic kubicyuma kitari ubushyuhe bwo hejuru burashobora kugurishwa cyane. Urimo kubikora kubintu bigoye kandi hafi-net-shusho yinyungu, ntabwo kuberako amavuta abisaba. Twigeze gutunganya abashoramari Amavuta 1 turbine sensor bracket yashoboraga kuba yarashushanyijeho, ariko imiyoboro yimbere yari igoye kuburyo kuyikora byikuba kabiri. Igihembo rero cyibikorwa byishoramari byari bifite ishingiro. Nibara rihoraho.
Umutego nyawo ni ugutekereza ibintu bifatika biva kubatanga ibintu bitandukanye. 'Alloy 1' kuva muri Mill A irashobora gukora imashini nkamavuta, mugihe kuva muri Foundry B ikora-ikarya ibikoresho. Itandukaniro akenshi riba mubintu bikurikirana hamwe na deoxidation imyitozo mugihe cyo gushonga. Aluminium yiciwe na silicon-yiciwe? Irahindura ibintu byose kumanuka. Utezimbere icyifuzo cyinkomoko, ntabwo gishingiye kubiciro gusa, ahubwo nukuntu byavuzwe ko ibikoresho byabo bitwara kumashini za CNC.
Imashini ya CNC: Aho Igitekerezo gihurira na Toolpath
Aha niho reberi ihurira n'umuhanda. Ku mpapuro, Amavuta 1 ifite ibipimo byimashini. Mubikorwa, ibyo bipimo ni igitekerezo. Ikintu cya mbere dukora nicyiciro gishya ni ukugabanya ikizamini. Turimo gushakisha uburyo bwo gukora chip. Ikirangantego, gikomeza ni inzozi zo kwikora kandi nikimenyetso dushobora gukenera guhindura ibiryo cyangwa inguni. Icyiza ni icyacitse, 'C-shusho. Hamwe na hamwe Amavuta 1, urabibona byoroshye. Hamwe nabandi, urimo uhindagurika hamwe na coolant concentration hamwe na chip-breaker geometrie umunsi wose.
Kwambara ibikoresho ni umwicanyi ucecetse. Ntabwo ari nko gutunganya ibyuma bidafite aho ubona byubatswe byubatswe bigaragara. Hamwe na Amavuta 1, kwambara kumpande ni buhoro. Urashobora kubona ubuso bunini kurangiza kubice mirongo itanu byambere, hanyuma mugice cya mirongo itanu na rimwe, utangira kubona amarira make cyangwa gutembera kurwego. Niba ukoresha itara ritagenzuwe-umusaruro, ibi birashobora kwangiza pallet yose yibikorwa. Ibi twabyize inzira igoye hakiri kare hamwe numubare munini wa valve umubiri wakazi. Dushiraho ibikoresho byubuzima dushingiye kumpapuro zamakuru. Urupapuro rwamakuru rwari rufite icyizere. Twarangije dufite ibice ijana byo kwihanganira mbere yuko ibikoresho byo kunanirwa bitangira. Noneho, twubaka murwego rwo kubungabunga umutekano no kugenzura imitwaro ya spindle mumadini.
Coolant ntabwo ari iyo gukonjesha gusa; ni amavuta yo kwisiga. Kuri Amavuta 1, igice cya sintetike ikonjesha hamwe namavuta meza ikunda gukora neza kuruta sintetike igororotse. Igabanya imbaraga zo guca kandi ifasha mukwimura chip. Ariko rero ugomba gucunga amavuta ya tramp no gukura kwa bagiteri cyane. Guhitamo kwose ni ugucuruza.
Imirongo idasanzwe
Kuki no gukoresha Amavuta 1 mugihe ufite cobalt cyangwa nikel ishingiye kuri superalloys? Nibisanzwe 'bikwiranye-intego'. Nagize uruhare mu mushinga wo gutunganya imiti. Umukiriya yabanje guhamagarira nikel ivanze kubice byose bitose kubera 'kurwanya ruswa.' Nyuma yo gusuzuma ibitangazamakuru nyaburanga-byoroheje byangiza ubushyuhe bw ibidukikije - twasabye icyiciro cyiza cya Amavuta 1 (variant ya 316L, muricyo gihe). Kuzigama ibiciro byari hejuru ya 60%, ntabwo mubikoresho gusa, ahubwo mugihe cyo gutunganya. Igice kimaze imyaka irindwi gikora ntakibazo. Ubushake bwo kurenza urugero burakomeye, cyane cyane munganda zagenzuwe, ariko uburambe burakwigisha gusubiza inyuma hamwe namakuru hamwe nibindi bisubizo.
Ibyo byavuzwe, gukorana na exotic alloys biguha gushimira byimazeyo idirishya ryo gutunganya Amavuta 1. Nickel alloys iragaragara neza iyo ikozwe, ibinini bya cobalt biragoye kubimashini. Amavuta 1 ni, ugereranije, kubabarira. Ariko 'kubabarira' ntibisobanura 'byoroshye.' Bivuze ko marge yamakosa ari yagutse, ariko amakosa aracyabaho niba utitonze. Ni itandukaniro riri hagati yo gutwara mumuhanda mugari no kunyura kumusozi muto; uracyakeneye kwitondera.
Kuri QSY, kuba bifata impande zombi za spekure - kuva kumavuta asanzwe kugeza kubidasanzwe - ninyungu nyayo. Bisobanura gahunda yo gutegura akazi muri Amavuta 1 amenyeshwa na disipuline ikabije isabwa kuri superalloys. Ibyo gukomera biratemba.
Kunanirwa n'amasomo twize
Ibihe byigisha cyane biva kunanirwa. Hariho igiti, hafi 75mm z'umurambararo, cyerekanwe muri Amavuta 1 n'imbaraga ndende. Kwinjira byakomanze nyuma yo gukora. Mugupima, yateje imbere imirasire. Ikosa ryambere ryagiye kumashanyarazi. Nyuma yinyuma-yinyuma-nyinshi, twakurikiranye inyuma gushonga. Ibikoresho byari bifite hejuru gato ugereranije nibisanzwe bya sulfuru, ibyo bikaba byaremye manganese sulfide ndende. Ibi byagize uruhare runini mugihe cyo gushyushya byihuse no kuzimya gukomera. Ibikoresho byujuje ubuziranenge bwa chimique kurwego rwicyemezo, ariko byari kumpera yumurongo wa sulfure. Isomo? Kubintu bikomeye, nyuma yo gutunganya ibice byavuwe nubushyuhe, ugomba gukaza umurego ibintu birenze urwego ASTM rusanzwe no kwerekana kugenzura. Wishyura byinshi kubishonga, ariko uzigama amahirwe yo kwirinda gutsindwa kumurima.
Ubundi busanzwe, hafi yubusa, uburyo bwo gutsindwa ni galvanic ruswa. Bolting an Amavuta 1 (vuga, ibyuma bya karubone) flange kumuyoboro wicyuma udafite ingese. Nibanze, ariko mubiterane bigoye hamwe nibikoresho byinshi, birengagizwa. Uwiteka Amavuta 1 ibice bihinduka igitambo anode kandi ikangirira kure. Ntabwo ari kunanirwa kubintu; ni igishushanyo mbonera no kugenzura inteko. Urabona ibi bice bigaruka kubw 'kwambara imburagihe,' kandi gukosora ni $ 0.50 gasi.
Ibyo kunanirwa nibyo byubaka ubumenyi bwinzego muri sosiyete. Niyo mpamvu iduka rifite imyaka 30 yamateka, nkiri inyuma tsingtaocnc.com, ifite agaciro karenze imashini yayo. Birashoboka ko bahuye kandi bagakemura ibyo bibazo byihariye, bikomeye.
Kurangiza nta mwanzuro
Noneho, ibyo bidusiga he? Amavuta 1? Ntabwo ari ingingo ushobora kurangiza neza. Nibikoresho byasobanuwe no gutunganya. Imikorere yacyo ni ubufatanye hagati ya metallurgiste, injeniyeri yubushakashatsi, programu ya CNC, hamwe nubushyuhe. Ntushobora kugura 'Alloy 1' gusa no gutegereza ibisubizo. Ugomba kubisobanura, kubishushanya, kubitema, no kubifata ufite intego runaka mubitekerezo.
Ubuhanga nyabwo buri mukumenya gukuramo gukurura porogaramu. Irakeneye anneal isanzwe cyangwa kuzimya no kurakara? Byakagombye kuba bikozwe neza mbere yo kuvura ubushyuhe hanyuma bikarangira bikozwe, cyangwa urashobora kubikora byose muburyo bwa anneed? Nta gisubizo kimwe. Impapuro zamakuru ziguha aho utangirira, ariko inzira yanyuma yuburyo bwanditse binyuze mubigeragezo, kwibeshya, no kwitegereza hasi yububiko.
Amaherezo, Amavuta 1 ni gihamya yigitekerezo cyuko mubikorwa, nta bikoresho birambirana, gusa inzira zidasobanutse neza. Irasaba kubaha atari kamere yayo idasanzwe, ahubwo isabwa kuba hose hamwe nuburyo bworoshye bwo gutandukana kwayo. Kubona neza burigihe, icyiciro nyuma yicyiciro, umwaka nuwundi, nicyo gitandukanya iduka ryakazi nabafatanyabikorwa nyabo bakora. Nibikorwa bidashimishije, burimunsi bituma inganda zihinduka.
