Ubona i-HT250 kumzobo, kwaye kulula ukucinga ukuba yenye intsimbi engwevu. Izinto eziqhelekileyo. Kodwa kulapho inkathazo eninzi iqala khona-icinga ukuba yinto yorhwebo. Kwiminyaka yam yokujongana ne-castings, ukusuka ekufuneni ukuya kumatshini wokugqibela, ndifumene ukuba i-HT250 yinto echazwe yinkqubo yayo kunye nokwakheka kwayo. I-'HT' imele i-iron cast engwevu, kwaye i-'250' yeyona nto incinci yamandla e-MPa. Isandi ngokuthe ngqo, kodwa ukubetha loo 250 ngokungaguquguqukiyo, inxalenye emva kwenxalenye, ngakumbi kwiijometri ezintsonkothileyo okanye amacandelo anodonga olubhityileyo, kulapho isakhono se-Foundry sahlukana nabanye. Ayikokunyibilika kwentsimbi kuphela; imalunga nokulawula ubume be-graphite flake, amazinga okupholisa, kunye nokulawula uxinzelelo olukhoyo. Ndibone iiprojekthi ezininzi zikhubeka ngenxa yokuba umntu uphathe i-spec njenge-odolo yokuthenga elula ngaphandle kokuqonda ukuba yintoni esemva kwayo.
Inyani yoMgangatho weFoundry
Xa sithetha nge-HT250 kunye ne-Foundry efana ne-Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), incoko ngokukhawuleza iyenzeka. Iminyaka yabo engamashumi amathathu kwiqokobhe kunye nokuphosa utyalo-mali kuthetha ukuba bagalele intsimbi eninzi. Into yokuqala abaza kuyibuza ayipheleli nje ngebanga; imalunga nomsebenzi wenxalenye, ukuguquguquka kobunzima bodonga, kunye nalapho iindawo ezinoxinzelelo oluphezulu zikhoyo. Umzekelo, umzimba wevalvu kunye nendlu yegiya zinokubiza zombini HT250, kodwa inkqubo yokungena kunye noyilo lwesikhuphukeli lunokwahluka ngokupheleleyo ukuqinisekisa isandi kwiindawo ezibalulekileyo. Ngokuphosa iqokobhe lokungunda, elisebenza ngokukhethekileyo kwi-QSY, ufumana ukugqiba okungcono komphezulu kunye nokuchaneka komda xa kuthelekiswa nesanti eluhlaza, kodwa yomelela ngokukhawuleza. Likrele elintlangothi-mbini leyo HT250-inokuphucula i-graphite structure, ekulungele ukomelela, kodwa ukuba ayilawulwa, inokukhuthaza ukupholisa (ukwenza intsimbi emhlophe, e-brittle) kumacandelo amancinci okanye iikona ezibukhali.
Ndikhumbula ibhetshi yezibiyeli zempompo esasizenzile kwiminyaka embalwa edlulileyo. Umzobo uchaziwe HT250, kwaye iisampulu ziphumelele uvavanyo lwe-tensile. Kodwa ebaleni, iiyunithi ezininzi zenze iintanda kufutshane nemingxunya enyukayo. Uhlalutyo lokungaphumeleli lubhekisele kwiindawo ezihlala kwindawo ephezulu ye-carbide-ngokuqinisekileyo, amabala ensimbi epholileyo-kanye apho ikona yangaphakathi ebukhali yenziwe khona. I-Foundry yayiyiphosile ngenxa yokuba ikhuphoni yovavanyo evela kwinkqubo yembaleki ibonise iipropati ezigqibeleleyo. Sifunda ntoni? Ipropati yezinto eziphathekayo ngumyinge; ukusilela kwenzeka kwindawo ebuthathaka yendawo. Kwafuneka sisebenze kunye ne-Foundry ukuguqula uyilo nge-fillet enkulu kwaye silungelelanise i-coating yokungunda ukucotha ukupholisa kuloo ndawo. Yayingelotshintsho kwibakala lezinto eziphathekayo; yayilutshintsho kwindlela esiyifezekise ngayo loo jiyometri.
Kulapho amava eqabane abonisa khona. I-Foundry egcwalisa iodolo iya kuba netyala loyilo lwethu. Isiseko sobugcisa sibandakanyeka kwingxaki. Ukujonga iphothifoliyo ye-QSY kwi-tsingtaocnc.com, uyabona ukuba baphatha uluhlu olulula ukuya koluntsonkothileyo. Loo mava aguqulela ekwazini, phantse ngokwethuku, apho imigibe enokubakho efana ne-shrinkage porosity okanye ukubanda inokuthi yenzeke kwindawo entsha, kwaye baya kuhlala beyiflegi ngexesha lophononongo lweDFM (uYilo lokuVeliswa). Ixabiseke kakhulu loo nto.
Machining HT250: Incoko kunye nothuli
Ukufumana ukuphoswa kwesandi sisiqingatha kuphela sedabi. Esinye isiqingatha siyayenza. HT250 inobuchule obulungileyo ngenxa yeeflake zegraphite ezisebenza njengeziqhekezi zetshiphu kunye nokubonelela ngokuthambisa. Kodwa i-abrasive. Itya ngokusebenzisa izixhobo eziqhelekileyo. Ukuba wenza umatshini olandelayo we-CNC, obonelelwa yi-QSY njengenkonzo ehlanganisiweyo, isicwangciso sendlela yesixhobo kunye nokukhethwa kwezixhobo zesixhobo kuba ngundoqo. Awunakuqhuba nje iiparamitha ezifanayo onokuthi uzisebenzise kwintsimbi ethambileyo.
Oku sikufunde kabuhlungu kumsebenzi onzima. Sasinazo ezi HT250 ii-manifolds ezifuna ukungqusha okuchanekileyo kubuso beflange kunye nokugrunjwa kwemingxunya yezibuko ezininzi. Ukuveliswa kwemveliso yokuqala kusetyenziswe izixhobo ze-carbide ezingafakwanga. Izixhobo ziye zaphela ngokukhawuleza kangangokuba ukunyamezelwa kwe-dimensional kwakhukuliseka ngaphandle kwe-spec ngenxalenye ye-20, kwaye isiphelo somphezulu siye sawohloka. Uthuli lwegraphite lwalukuyo yonke indawo, luvale iingcingo zokupholisa. Ibiyingxubakaxaka. Isisombululo yayingezozixhobo ezibiza kakhulu, kodwa zazikrelekrele. Sitshintshele kwi-polycrystalline diamond (i-PCD) efakela imisebenzi ejongene nayo kwaye sasebenzisa iidrill ezigqunywe nge-carbide ezinejometri ezikhethekileyo zentsimbi ekhatywayo. Ubomi besixhobo bunyuke ngomlinganiselo we-15, kwaye umba wothuli wathotywa ngesipholisi soxinzelelo oluphezulu olujolise ngokuchanekileyo ukukhupha iitshiphusi, hayi nje ukupholisa.
Umthengisi odityanisiweyo ophatha zombini ukuphosa kunye nomatshini, njengeenkonzo ezichazwe kwi-https://www.tsingtaocnc.com, unenzuzo enkulu apha. Banokwandisa inkqubo yokuphosa ukushiya isibonelelo esingaguqukiyo nesaneleyo somatshini. Kwakhona bayayazi imeko echanekileyo yezinto abazivelisayo-ubunzima bayo, naziphi na iindawo ezinzima ezinokubakho-kwaye banokubeka iinkqubo zabo ze-CNC ngokufanelekileyo kwasekuqaleni. Akukho kwalatha ngomnwe phakathi kwendlu yokuphosa kunye nevenkile yomatshini xa isixhobo siphuka kwindawo enzima; liqela elinye elixazulula ingxaki enye.
Umbuzo odibeneyo kunye neengcamango ezingezizo
Ngamanye amaxesha, abaqulunqi babona imfuneko yamandla kwaye bacinge, Masenze nje izinto ezingaphezulu zokudibanisa. Kuba HT250, ukubunjwa okusemgangathweni ngokuyinhloko yintsimbi, i-carbon, kunye ne-silicon, kunye namanqanaba alawulwayo okungcola njengesulfure kunye ne-phosphorus. Unokomeleza amandla ngokongeza amanani amancinci echromium, imolybdenum, okanye ubhedu, kodwa ukongezwa ngakunye kutshintsha ezinye iipropathi. I-Chromium yonyusa ukuqina kunye nokunganyangeki kokunxiba kodwa yenza ukuba i-iron ithande ukugodola kwaye ibenzima kumatshini. Lurhwebo-off.
Ukungaqondi kakuhle okuqhelekileyo kukuba i-iron yomgangatho ophezulu (njenge-HT300 okanye i-HT350) ihlala ingcono HT250. Ayonyani. Ukuba inxalenye yakho ayifuni amandla ongezelelweyo, uhlawulela imathiriyeli kunye neendleko zokulungisa ongazidingiyo, kwaye unokuba ungenisa ubunzima obungeyomfuneko bomatshini. Undoqo kukufaneleka kwezinto eziphathekayo. Kwizinto ezininzi zolwakhiwo, iibhlokhi ze-injini, okanye iziseko zesixhobo somatshini apho ufuna ukuthomalalisa kakuhle kokungcangcazela, amandla okucinezela, kunye nokuphosa, HT250 Ihlala ilolona khetho lufanelekileyo, olungenaxabiso. Umthamo wayo wokumanzisa ungaphezulu kunentsimbi, yiyo loo nto ixhaphake kakhulu kwiibhedi zoomatshini.
Kuluhlu lwabo lwezinto eziphathekayo, i-QSY ikhankanya ukusebenza ngee-alloys ezikhethekileyo ezifana ne-nickel-based based. Lo mxholo ubalulekile. Indixelela ukuba bayayiqonda i-metallurgy. Xa besebenza kunye HT250, abayithathi njengento nje elula; Basebenzisa umgangatho ofanayo wolawulo lwenkqubo kunye nokuqonda ngesinyithi abaya kwenza kwi-alloy esebenza kakhulu. Loo ngqondo ibalulekile kukungaguquguquki.
Umgangatho ukwiiNgcaciso ezingabonakaliyo
Wazi njani ukuba ulungile HT250? Izatifikethi zisisiqalo, kodwa zizifitshane nje. Umgangatho wangempela wakhiwe kwinkqubo yokulawula inkqubo: ubushushu bentsimbi etyhidiweyo, i-inoculation practice (ukongeza inani elincinci lezinto ezifana ne-ferrosilicon ukulawula ukubunjwa kwegraphite), ukushisa kwe-mold, kunye nokunyangwa kobushushu. Ewe, unyango lobushushu. Ngelixa HT250 Ihlala isetyenziswa kwimeko yokuphosa, ukunciphisa uxinzelelo kubalulekile kwiindawo ezintsonkothileyo okanye ezichanekileyo ukuthintela intshukumo yedimensional ngexesha okanye emva komatshini.
Ndandwendwela i-Foundry kanye eyayinolawulo oluhle kakhulu ephepheni. Kodwa phantsi, ndaphawula ukuba isitofu sasongezelelwa kwileyile ngendlela engacwangciswanga—ngamanye amaxesha kwakusasa, maxa wambi emva kwexesha, maxa wambi isixa sasitsalwa ngeliso. Ukungahambelani kuchaphazela ngokuthe ngqo ubungakanani be-graphite flake kunye nokusabalalisa, nto leyo echaphazela amandla okuqina kunye nobuqili. Amalungu asenokuthi akhuphe ngaphaya kwe-250 MPa ubuncinci, kodwa ukwahluka ukusuka kwinxalenye ukuya kwinxalenye kuya kuba phezulu, kubangele intloko ebuhlungu kwiiseli zomatshini ezizenzekelayo.
Kungenxa yoko le nto ubomi obude benkampani, njengeQSY's 30 iminyaka, bunokuba ngummeli woqeqesho lwenkqubo. Baye babona ukuba zeziphi iindleko zokungahambelani kwaye baneenkqubo, nokuba zisisiseko, ukuyithintela. Ngumahluko phakathi kweworkshop kunye nomthengisi wefektri. Xa ndijonga amandla abo okulandela ngeCNC machining, icebisa ukuba baqonde lonke ikhonkco lexabiso, ukusuka kwinyibilika ukuya kwindawo egqityiweyo. Bayazi ukuba ukuphosa okungalunganga akunakugcinwa kwinqanaba lomatshini, ke kuya kufuneka bayifumane ngqo kumthombo.
Ukuyisonga: Isixhobo esikumxholo
Ke, emva kwayo yonke le nto, ndithatha ntoni HT250? Yimathiriyeli yehashe ekhohlisayo ilula. Ukuyichaza yeyona ndawo ilula. Umsebenzi wangempela usekusebenzisaneni kunye ne-Foundry eqonda ama-nuances ayo kwaye inokuguqulela umzobo we-2D kwinxalenye ye-3D kunye nesakhiwo esifanelekileyo sangaphakathi kunye neepropati. Imalunga nokuyijonga kungeyiyo ikhowudi yorhwebo, kodwa njengesixhobo sobunjineli esintsebenzo yayo yokugqibela ingumsebenzi woyilo, uqheliselo lwesiseko, kunye neqhinga lomatshini.
