Xa abantu abaninzi besiva 'izixhobo zokulungisa ukutya', baba nomfanekiso koomatshini bentsimbi ecwebezelayo - izisika, izixube, ii-oveni. Into ephoswayo, phantse rhoqo, ngamalungu. Iigiya, iishafti, izindlu, iivalvu, kunye nezinto ezizifakelweyo ezenza abo matshini basebenze. Lushishino lwakudala lokubek' iliso: ukugxila kulo lonke ngelixa ujongela phantsi ukubaluleka kwamacandelo. Inyani yeyokuba, icandelo elinye elisezantsi-impompo engaphoswanga kakuhle okanye i-shaft drive engachanekanga-inokuthi imise umgca wemveliso wonke, ibangele umngcipheko wosulelo, okanye iguge nje emva kwamawaka ambalwa emijikelo xa kufuneka ihlale amashumi amawaka. Olwam uluvo, oluye lwenziwa ukutyhubela iminyaka yokukhangela kunye nokucombulula iingxaki, kukuba iindawo kulapho umlo wokwenyani wobunjineli kunye nezinto eziphathekayo usilwa khona. Ayiyonto intle, kodwa yinto yonke.
Isixhobo asiloPhepha nje eliKhethekileyo
Ufumana umzobo othi 316 intsimbi engatyiwayo okanye intsimbi etyhidiweyo yeBanga 250. Sisiqalo eso, hayi isiphelo. Kwiindawo zezixhobo zokulungisa ukutya, i-spec isisiseko. Uvavanyo lokwenyani lukwimo yesicelo. Ingaba isikrurufu sesixhobo esomileyo sokuhambisa? Indlu yempompo yokujikeleziswa kwebrine emanzi? Ilungu lobushushu obuphezulu, inkqubo yokutofa ngomphunga woxinzelelo oluphezulu? Imeko nganye ifuna ngaphezulu kwebakala elisemgangathweni. I-316L inokuchazwa, kodwa kwiindawo ezine-acidic, umxholo wekhabhoni ephantsi kunye nolawulo oluchanekileyo lwe-molybdenum luba lungenakuxoxisana ukukhusela i-corrosion pitting. Ndibone iinxalenye zisilela hayi ngenxa yokuba ziyi-alloy engalunganga ephepheni, kodwa ngenxa yokuba i-Foundry's melt practice yazisa ukungahambelani, okanye unyango lobushushu aluzange lwenzelwe iindawo ezithile zoxinzelelo.
Kulapho ukusebenzisana nomsunguli oyingcali kunye noomatshini benza umahluko obonakalayo. Inkampani efana Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), kunye neminyaka yabo engamashumi amathathu ekujuleni nasekusebenzeni, bayayiqonda le nuance. Akukhona nje ngokugalela isinyithi; imalunga nokwazi ukuba a iqokobhe ngundo ukuphosa kumzimba wevalve yokutya obhityileyo, onzima udinga isango lokungena kunye nenkqubo yokunyuka kunesixhobo esinzima seyunithi yokuqhuba. Umsebenzi wabo onama-alloys akhethekileyo, njenge-nickel-based based, ibaluleke kakhulu kwiindawo ezivezwe kwi-corrosion egqithisileyo okanye ukushisa - cinga ngeevalve ze-homogenizer okanye amacandelo athile okutshintsha ubushushu. Ukhetho lwezinto eziphathekayo luchaza ngokuthe ngqo ukuphosa kunye nokulandelayo CNC Machining iqhinga.
Intloko ebuhlungu endiyikhumbulayo yayibandakanya i-auger endaweni yomxube womgubo. Eyokuqala, evela kwi-OEM, yahlala iminyaka. Ukutshintshwa kwethu komthombo wokuqala, ukuhlangabezana ne-spec yemathiriyeli, kuphuhliswe ii-microfractures kuhambo lwenqwelomoya kwisithuba seenyanga. Ingxaki? Ukulandelela ukubunjwa kwezinto kunye nenkqubo yokunciphisa uxinzelelo emva kokuphosa. Isifundo sasikhohlakele: umnombo wezinto eziphathekayo kunye nembali yokucubungula ayinakwahlulwa kwintsebenzo yecandelo. Uthenga isisombululo esenziweyo, hayi nje ukwakheka kweekhemikhali.
Indawo yokuhlangana echanekileyo: Ukuphosa kuhlangana noMatshini
Bambalwa kakhulu abagxekayo iindawo zezixhobo zokulungisa ukutya zifakwe nje okanye zenziwe ngoomatshini. Baphantse basoloko bobabini. Isingxobo sempompo sifakwe kwimilo ekufutshane nenethi, kodwa umphezulu wokutywina, imingxunya yebholiti, kunye namazibuko ojongano kufuneka enziwe ngoomatshini bokunyamezelana kumgangatho wemicron. I-handoff phakathi kwevenkile yokuphosa kunye nevenkile yomatshini yindawo enokubakho yokusilela. Ukuba ukuphosa kune-warpage encinci okanye i-shrinkage yangaphakathi engazange ibalwe, inkqubo ye-CNC inokuthi iqhube umoya kwelinye icala kwaye ibethe indawo enzima engalindelekanga kwelinye, iyonakalisa inxalenye kunye nesixhobo.
Imisebenzi edibeneyo iyayinciphisa le nto. Xa ukuphosa kunye CNC Machining ziphantsi kophahla olunye, njengakwiQSY, iluphu yempendulo iqinile. Oomatshini banokwazisa iqela le-Foundry ukuba bahlala befumana icandelo elincinci kwindawo ethile yokubumba, okanye ukuba i-alloy ethile iziphatha ngendlela eyahlukileyo ngexesha lokusika. Le ndawo idityanisiweyo ivumela into esiyibiza ngokuba luyilo lokwenziwa kokwenziwa ngexesha lokwenyani, hayi kwithiyori kuphela. Umzekelo, banokucebisa ukongeza i-engile eyidrafti encinci okanye irediyasi encinci ekoneni ngexesha loyilo lokubumba elingenzi mahluko usebenzayo kwicandelo kodwa liphucula kakhulu ukuphosa kunye nokugqiba komatshini.
Ndiyifunde le ndlela kabuhlungu kwangethuba, ndikhangela i-valve entsonkothileyo kubathengisi abahlukeneyo. Iicastings zazibukeka zigqibelele. Kodwa ngexesha lokucwangciswa kokugqibela ngomnye umntu, indawo eyinyani yamazibuko aliqela yayicinywe ngesiqingatha semilimitha – ngokwaneleyo ukuba ingahambelani kakuhle nemibhobho. Umdlalo wetyala uqalile: umseki wathi inkqubo ye-CNC ayilunganga, umatshini wathi i-datum yokuphosa itshintshiwe. Umthengisi odibeneyo uyakuphelisa ukukhombana ngeminwe. Uxanduva lokuphendula lukwisinye, kwaye ulwazi lwenkqubo luyakhula.
UkuGqiba komphezulu: Apho ucoceko luhlala khona okanye lufela khona
Oku kunokuba ngowona mba ubaluleke kakhulu kuqhagamshelwano lokutya, kwaye ihlala icwecwe kumzobo ngeRa 0.8 μm callout. Ukugqitywa komphezulu akukho malunga nokuguda nje; imalunga nokucoceka kunye nokuthintela izibuko lebhaktiriya. Ipolishi yesibuko (i-Ra 0.4 μm okanye ingcono) iyimfuneko kwimigangatho edibana ngokuthe ngqo nemveliso, ngokukodwa izinto ezibonakalayo okanye ezincangathi njengentlama okanye itshizi. Kodwa ukuphumeza loo nto ayingombandela nje wokuqhuba ivili lokupholisha igrit elicolekileyo.
Uhambo oluya kweso siphelo sokugqibela luqala ngokudlala. A iqokobhe ngundo okanye utyalo mali Inkqubo ngokwendalo ibonelela ngomphezulu ogudileyo njengokugxunyekwa kwesanti yemveli. Oku kuthetha ukuba isitokhwe esincinci kufuneka sisuswe ngexesha lomatshini, ukugcina imfezeko yezinto eziphathekayo kunye nokunciphisa umngcipheko wokuvezwa kwe-porosity engaphantsi komhlaba ngexesha lokupolishwa. Inkqubo yomatshini ngokwayo kufuneka icokiseke. Izicwangciso zendlela yesixhobo, amaxabiso esondlo, kunye nokusetyenziswa kokupholisa konke kuchaphazela umphezulu wokugqibela. Nakuphi na ukukrazula okuncinci, uphawu lokuncokola, okanye umaleko owenziweyo uba yindawo enokubakho yeentsholongwane.
Besinengxaki ngebhetshi yesikhokelo sokulungiswa kwenyama. Baluphumelele uvavanyo lweRa ngeprofilometer kodwa, phantsi kolwandiso, babonisa incoko yesixhobo esincinci. Enyanisweni, amanqatha kunye nezicubu bezihlala kule mijelo mincinane, nto leyo eyenza ugutyulo lube liphupha elibi. Ukulungiswa kwakubandakanya ukuhlaziya ukunyathela kwesixhobo se-CNC kunye nokusetyenziswa kwesixhobo esahlukileyo sokugquma. Zezi nkcukacha zegranular, eziphantse zibe ngaphaya kokwahlula indawo elingana nenxalenye esebenza ngokuthembekileyo ngendlela ekhuselekileyo ekutyeni. Ukuqhelana komnikezeli ngokugqitywa komgangatho wokutya, njengalezo zigunyaziswe yi-3-A Sanitary Standards okanye izikhokelo ze-EHEDG, sisihluzo esingaxoxisiyo kwinkqubo yokhetho.
Inyani yokusilela kunye nokuphindaphinda
Ayiyiyo yonke indawo esebenza ngokugqibeleleyo kwitry yokuqala, kwaye ukwenza ngathi ngenye indlela kukunganyaniseki. Ubuchwephesha bokwenyani bomenzi wamalungu buboniswa kwindlela abaphatha ngayo ukusilela kunye nokuphindaphinda. Kwiminyaka embalwa ebuyileyo, besilinganisa uhlobo olutsha lwesibambi seblade lokusika imifuno. Uyilo lwalunamabhongo - lubhityile-ludonga, lomelele, lufuna ukumelana nempembelelo yebhayisikile. Ukuphindaphinda okumbalwa kokuqala, ukuphoswa kwi-martensitic stainless, eqhekekileyo ngexesha lovavanyo lokukhathala.
Isisombululo asiveli kwincwadi yesikhokelo. Ivele kwintsebenziswano yokusombulula ingxaki. Iqela kwi QSY icebise ukutshintshela kwi-alloy esekwe kwi-cobalt kumandla ayo aphezulu wokudinwa kunye nokumelana nokunxiba. Nangona kunjalo, le alloy idume ngokuba nzima ukuphosa kunye nomatshini. Amava abo kunye ialloys ezikhethekileyo kwangena umdlalo. Baye bahlengahlengisa iiparamitha zenkqubo yokuphosa utyalo-mali - ubushushu be-preheat, isantya sokugalela - ukulawula ukuhamba kwesinyithi kunye nokuqiniswa kwale geometry ethile. I-Post-casting, baphuhlise unyango olulungiselelwe ubushushu obunamanqanaba amaninzi ukufezekisa ukulingana okufanelekileyo kobunzima kunye nokuqina. I CNC Machining emva koko kwafuneka aqhelane nezinto eziqinileyo, esebenzisa izixhobo ezikhethekileyo kunye nezantya. Ukuphindaphinda kwesihlanu kuphumelele. Le nkqubo - ukungaphumeleli, isayensi yezinto eziphathekayo, ukulungiswa kwenkqubo, impumelelo - ingundoqo engathandekiyo yokuphuhlisa ukuthembeka iindawo zezixhobo zokulungisa ukutya.
Kungenxa yoko le nto ubomi obude kule ntsimi bubalulekile. Inkampani ebikhe yadlula kwimijikelo emininzi yezoqoqosho kunye neenguqu kubuchwepheshe, njengequmrhu elineminyaka engama-30 ubudala, idibene kwaye yasombulula ithala leencwadi elikhulu leengxaki ezinjalo. Loo nkumbulo yeziko yi-asethi engabambekiyo kodwa ibalulekileyo. Awuthenganga nje ixesha labo lomatshini; uthengela ulwazi lwabo oluqokelelweyo, oludla ngokuphumelela nzima, malunga nento eyenza ukuba baphile kwihlabathi elohlwayayo lemveliso yokutya.
Ngaphaya kweCandelo: Ingqondo yeSixokelelwano soBonelelo
Okokugqibela, ukucinga malunga neenxalenye zodwa yimpazamo. Zikhona kwikhonkco lokubonelela. Amaxesha okukhokela, ukuhambelana kwebhetshi, ukulandeleka, kunye nesiqinisekiso zonke ziyinxalenye yemveliso. Kumphathi wesityalo sokutya, inxalenye ethile ayinamsebenzi ukuba ifike emva kweeveki ezimbini ngexesha lonyaka ophakamileyo. I-Consistency yinkosi - iyunithi ye-1000 kufuneka iqhube ngokufanayo neyokuqala.
Umenzi owomeleleyo ulawula oku ngokupheleleyo. Iwebhusayithi yabo, njengaye tsngtaocnc.com, kufuneka ibe yi-portal kolu kuthembeka, kungekhona nje ikhathalogu. Ithetha ngokuzibophelela kwiinkqubo ezithile (iqokobhe ngundo ukuphosa, utyalo mali, CNC Machining) kunye neentsapho zezinto eziphathekayo (ukusuka kwintsimbi etyhidiweyo ukuya kwii-alloys ezisekelwe kwi-nickel). Le ngqwalasela icebisa ubunzulu kunobubanzi. Ngamava am, amaqabane angcono kakhulu abo banokuchaza ngokucacileyo kungekhona nje into abayenzayo, kodwa njani kwaye kutheni beyenza indlela ethile yesicelo esinikiweyo.
