Xa usiva 'amalungu omgangatho woxinzelelo', iingqondo ezininzi zitsibela ngqo kwizinto ezinamatikiti amakhulu: iiroli zokusebenza, iiroli ezigcinayo, iicylinder zehydraulic. Nantso into yobukhazikhazi. Kodwa eyona ntloko ibuhlungu, izinto ezisila umgca wokuma ngoLwesibini emva kwemini, ihlala ihlala kwindawo exhasayo. Izindlu zokuthwala, iingalo zekhonkco, i-shafts eccentric, iindibano zesali. La ngamacandelo apho ukunyamezelana kuyinkosi, kwaye indawo ethi 'isondele ngokwaneleyo' yiresiphi yokungcangcazela, ukunxiba kwangaphambi kwexesha, kunye nomnxeba ongafuni ukuwufumana ngo-3 AM. Ndibone imisebenzi emininzi igxininise kuhlahlo lwabiwo-mali kuluhlu lo gama ndifumana ezi nxalenye zibalulekileyo zesakhiwo kunye nonxibelelaniso kubathengisi abangawuqondiyo umjikelo, ubume bemeko yomthwalo ophezulu abahlala kuwo. Luqoqosho olungeyonyani.
Amanqaku oxinzelelo angabonakaliyo: ngaphaya kwemiqulu
Makhe sithethe ngokuzala izindlu okomzuzwana. Ephepheni, yibhloko yentsimbi enomngxuma kuyo. Ngokwesiqhelo, lujongano phakathi komqulu ojikelezayo kunye nesakhelo esimileyo, esifunxa amandla amakhulu okujikeleza. Indlu ephoswe kwintsimbi eqhelekileyo ethambileyo ingaluphumelela uvavanyo lomthwalo omileyo, kodwa phantsi komthwalo wokudinwa kweleveli, inokuphuhlisa iintanda ezincinci. Ndikhumbula imeko apho isityalo sasisukela umcimbi wokungcangcazela. Batshintsha iirolls, i-balanced drives, imisebenzi. Umoni? A kancinane ngaphandle-of-spec bore kwizindlu ezitshintshiweyo ukusuka kwivenkile koomatshini jikelele. Yayingeyiyo i-diameter; yayiyicylindricity kunye nokugqitywa komphezulu. Ukuthwala kwakungahlali kakuhle, okukhokelela ekukhathazekeni kwaye ekugqibeleni, ukunkqonkqozwa. Isifundo yayikukuba kula macandelo, i iindawo zokunciphisa uxinzelelo ezenza amathambo omatshini, umgangatho wokuphosa kunye nokuchaneka komatshini akuxoxiswana.
Apha kulapho umnombo we-Foundry ubalulekile. Inkampani efana Qingdao Qiangsenyuan Technology Co., Ltd.(QSY) ifika engqondweni. Ngeminyaka engamashumi amathathu kwiqokobhe kunye notyalo-mali, bayaluqonda ulwakhiwo lwezinto eziziinkozo kunye nokuthembeka. Kwingalo yekhonkco ye-tension leveler, ebona imijikelezo yoxinzelelo lwe-tension-compression rhoqo, usebenzisa intsimbi eyenziwe ngokufanelekileyo okanye i-ductile iron-eyenziwe ngokunyamezela okuchanekileyo-yenza umahluko kubomi benkonzo onokuthi uyilinganise kwiinyanga okanye iminyaka, kungekhona nje kwi-spec sheet. Umsebenzi wabo onama-alloys akhethekileyo nawo ufanelekile kwizinto ezithile, ezinxitywayo eziphezulu kwiindawo ezinzima.
I-eccentric shaft ngomnye umzekelo weklasikhi. Yintliziyo yohlengahlengiso lwe-gap kumanqanaba amaninzi. Ukulingana phakathi kweshafti, amahlahla ayo, kunye nesali ibaluleke kakhulu. Ukukhululeka kakhulu, ufumana umdlalo kunye nokulinganisa okungahambelaniyo. Ukuxineka kakhulu, ubeka umngcipheko wokubamba ngexesha lokwandiswa kwe-thermal. Ndibe yinxalenye ye-retrofit apho sitshintshe i-assembly kunye neenxalenye ezivela kubaboneleli abahlukeneyo. Umatshini wenziwa ukuprinta, kodwa unyango lobushushu kwi-shaft alufani, nto leyo eyakhokelela kulwakhiwo oluncinci emva kweenyanga ezintandathu zenkonzo. Ulungelelwaniso lwaba lukhuni, abaqhubi balunyanzelise kakhulu, kwaye saphela sinokusilela. I-takeway? Onke amacandelo kwindlela yomthwalo, nokuba ijongeka njani na, i tension levelers inxalenye oko kufuneka kuphathwe ngolo hlobo.
Izinto eziKhethelwayo: AyiyoNtsimbi nje
Ukucacisa intsimbi yeplate yokugqoka okanye ibhloko yesikhokelo yindlela eqinisekileyo yokufumana inxalenye engaphumeleli ngokukhawuleza kunokuba ifanele. I-abrasion evela kumtya, ngakumbi ukuba usebenzisa i-hot-rolled pickled kunye ne-oyile (HRPO) okanye iintsimbi ezithile ezinokuqina okuphezulu, bubundlavini. Intsimbi yekhabhoni eyi-1045 inokuba ilungile kumgca wevolumu ephantsi, kodwa kumgca we-tandem oqhubekayo, ujonge iintsimbi zesixhobo eziqinileyo okanye ukudibanisa ne-tungsten carbide inserts. Inzululwazi yezinto eziphathekayo emva kolu khetho kulapho iindleko zokusebenza zokwenyani zigcinwa khona.
Oku kuhambelana nezakhono zomenzi okhethekileyo. Ukujonga kwipotfoliyo yomthengisi, njengaleyo ungayifumana kuyo https://www.tsingtaocnc.com, ikuxelela into abayilungiselele yona. Ukuba badwelisa i-nickel-based okanye i-cobalt-based alloys kunye neminikelo yabo eqhelekileyo, ibonisa ukuqonda ukuguga kunye nokumelana nokubola okufunekayo kumatshini woshishino. Umzekelo, isikhokelo sokungena okanye sokuphuma somgangatho woxinzelelo esenziwe ngentsimbi engatyiwayo (efana ne-CF-8M) inokunciphisa kakhulu i-galling kunye ne-particle ye-particle xa kuthelekiswa ne-standard carbon steel part, ukuphucula umgangatho we-strip surface.
Imowudi yokusilela esihlala singayihoyi kukudinwa. Amalungu awasoloko eqhekeka kumthwalo omnye; bafa kwiwaka lemijikelo emincinci. Intonga yokudibanisa kwi-level's drive linkage is a prime candidate. Ukukhetha imathiriyeli enamandla okudinwa okufanelekileyo, okufana nentsimbi eyintsimbi edibeneyo, kunye nokuqinisekisa ukuba umatshini awazisi izinyusi zoxinzelelo (iikona ezibukhali, ukugqitywa komphezulu ombi kwiindawo zeefillet) kubalulekile. Ndizibonile iintonga zisilela kwicandelo elinemisonto ngenxa yokuba ingcambu yomsonto yayitshintshwe kabukhali kakhulu, isenza indawo yokuqalisa yokuqhekeka egqibeleleyo. Zezi nkcukacha ezahlula inxalenye esebenzayo ukusuka ethembekileyo tension levelers inxalenye.
I-Machining & Fit Conundrum
Nokuba kukho ukuphosa okugqibeleleyo okanye ukubunjwa, umsebenzi wenziwa nje ngesiqingatha. CNC machining kulapho inxalenye ifumana indawo yayo kumatshini. Kumalungu endibano, asithethi nje ngemilinganiselo; sithetha ngokunyamezela kwejometri-i-parallelism, i-perpendicularity, indawo yokwenyani. Ubuso obuxhomayo bebloko yevalve yekhatriji yehydraulic kwisakhelo senqanaba kufuneka sibe sicaba kwaye sibe nomphezulu ofanelekileyo ukugqiba ukuthintela ukuvuza kwangaphandle. Umsebenzi obonakala ulula, kodwa ukuba ulandelelwano lomatshini alulunganga, uxinzelelo olushiyekileyo kwindawo lunokubangela ukuba lugqwetheke emva kokuba lungafakwanga elukhukweni.
Ivenkile eyenza kuphela ukukhanya okulula kuya kuba nzima apha. Udinga umthengisi onecandelo lomatshini we-CNC eliqhelile kwiindawo ezinzima, ezinzima. Kufuneka baqonde indlela yokulungisa ukuphosa okukhulu, okungaqhelekanga njengesakhelo secala lenqanaba loxinzelelo ngaphandle kokwenza uxinzelelo, kunye nendlela yokufezekisa ukuhambelana kwibhetshi. Xa ufuna iindibano ezine zesali ezifanayo, kufuneka zifane ngokwenene, hayi nje ngaphakathi konyamezelo loshicilelo, kodwa ngokungaguquguqukiyo okuqinisekisa ukuba ziziphatha ngokufanayo phantsi komthwalo. Eli nqanaba lolawulo lilo elivumela iishedyuli zokulondolozwa kwangaphambili.
Emva koko kukho ukulingana. Utshintsho ukusuka kwisilayidi ukuya kwisilungelelaniso sokuphazamiseka sisigqibo esisekelwe kumsebenzi, kwaye ukuyifumana ingalunganga kuyabiza. Kwiphini elidibanisa iingalo ezimbini ezinxibelelanayo, ungafuna into etyibilikayo enengono yegrisi. Ukuthwala okucinezelwe kwi-shaft, udinga ukuphazamiseka okulawulwayo. Ndikhumbula isakhiwo apho sasisebenzisa i-gearbox entsha. I-shaft ye-output yenzelwe ukunyamezela okusemgangathweni kwi-bearing fit. Nangona kunjalo, indawo yokuhlala esasinayo (indawo endala, egciniweyo) yayiyeyona nto iphezulu yokunyamezela kwayo. Isiphumo sokulingana sasikhululekile kakhulu. Asizange siyifumane ebudeni bendibano, yaye kwiiveki nje ezimbalwa, loo ntambo yajikeleza indlu, yazaphula zombini. Ukulungiswa kwakubandakanya ukwenza oomatshini bezindlu kunye nokufakela i-sleeve—ixesha lokuphumla esasingenakulihlawula. Ibethelele into entsha ehambelanayo iindawo zokunciphisa uxinzelelo ngeziseko ezingundoqo esele zikhona zifuna okungaphezulu nje kokukhangela i-micrometer; ifuna inkqubo yokucinga.
Ukungaphumeleli kokwenyani kwehlabathi kunye nokuphindaphinda
Ufunda ngakumbi kucazululo kunencwadi yesikhokelo. Besinomgca wokuqhubekeka wokuqhubekeka apho iirola zemoto zetension leveler's entry looper zihlala zibamba. Iirola ngokwazo bezilungile, kodwa ii-asi stub ebebezijikelezisa bezisilela. Uyilo lwantlandlolo lusebenzise i-shaft eqinisiweyo enesihlahla esiqhelekileyo sobhedu. Imekobume yayifudumele yaye inothuli. Imowudi yokungaphumeleli yayikukunxitywa kwe-abrasive kwi-shaft kunye ne-adhesive wear (i-galling) kwi-bushing. Ulungiso lwethu lokuqala yayikukuba i-chrome-plate i-shafts. Kwanceda, kodwa iplating ekugqibeleni yaqhekeka.
I-iteration yesibini, esebenzayo, yayiyimpahla epheleleyo kunye noshintsho loyilo. Sithathe ii-asi ze-stub ezitsha ezenziwe ngentsimbi eqiniweyo enobunzima obuphezulu bomphezulu, kwaye sadityaniswa namatyholo obhedu amiliselwe yigraphite evela kwingcaphephe efana ne-QSY, enokuphosa kunye nomatshini wokudibanisa izinto ezithile. Igraphite yayibonelela ngokuthanjiswa okomileyo, ukumelana nothuli. Esi yayingesosisombululo sangaphandle; ibiyintsebenziswano phakathi kweqela lethu lolondolozo kunye nesiseko sobugcisa/ivenkile yomatshini ukwenza injongo eyakhelweyo tension levelers inxalenye. Luhlobo lokusombulula ingxaki oluchaza umsebenzi ozinzileyo.
Omnye umgibe oqhelekileyo kukucinga ukuba zonke iziqhoboshi ziyalingana. Iibholiti ezibambe i-level's roll chock endaweni ziphantsi koxinzelelo olukhulu lokucheba. Ukusebenzisa ibholithi esemgangathweni yeBanga lesi-5 endaweni yokuqina okuphezulu kweBanga lesi-8 okanye ibholithi yentloko yealloyi yesokethi kunokukhokelela ukolula kwaye, ekugqibeleni, ukwaphuka. Kubonakala ngathi iyinto engenamsebenzi, kodwa ibholiti eyaphukileyo kumngxunya oyimfama ocofayo kwindawo enkulu yokuphosa liphupha elibi lokulungisa iiyure ezininzi. Ngoku, sichaza kwaye sikhuphe iziqhoboshi njengenxalenye yayo nayiphi na ikhithi yecandelo, sibaphatha njengezinto zokunxiba ezibalulekileyo.
Ukufumana iPhilosofi yexesha elide lokuphumla
Ke, yeyiphi indlela yokujonga? Imalunga nokwakha ikhonkco lokubonelela ngokuthembeka, hayi nje ngexabiso. Kwisiseko esisisiseko kunye nokunxiba okuphezulu iindawo zokunciphisa uxinzelelo, ufuna amaqabane athetha ulwimi lwesinyithi kunye nomatshini ochanekileyo, hayi nje ukuthenga. Ufuna umthengisi obuza imibuzo: Lithini iqondo lobushushu lokusebenza? Ithini ifrikhwensi yomjikelo? Yintoni eyasilelayo kwindawo endala? Iwebhusayithi efana nale yeQingdao Qiangsenyuan Technology, ebonisa imbali ende ekujuleni nasekusebenzeni iialloyi ezahlukeneyo, sisiqalo esihle sobunzulu.
Ikwamalunga nokucwangcisa ukuphelelwa lixesha. Abaninzi abakumgangatho wenkonzo bangamashumi eminyaka ubudala. Abavelisi bezixhobo zoqobo (OEMs) basenokungasabaxhasi, okanye amaxesha okukhokela akavumelekanga. Ukuba nomthombo wesibini othembekileyo wokwenza la malungu-onokuthi abuyisele umva-injineli ukusuka kwisampulu egugileyo, acebise ngokuphuculwa kwezinto, kunye nokuhambisa inxalenye egqityiweyo, enomatshini-ixabiseke kakhulu. Oku kuguqula indawo yokumisa iveki yonke ibe yimpelaveki ecetywayo.
Ekugqibeleni, bhala yonke into. Xa ufumana isisombululo esisebenzayo-isixhobo esitsha somtya wokunxiba, ukunyamezela okutshintshileyo kwi-shaft, umthengisi othile wezinto zentsimbi ye-cast ductile-zibhale. Yakha eyakho idatabase yangaphakathi. Inkumbulo edibeneyo yento esebenza koomatshini bakho abathile kunye nomxube wemveliso yeyona asethi yakho ibaluleke kakhulu. Iguqula ingqikelelo 'yeendawo zomgangatho woxinzelelo' ukusuka kuluhlu lwezinto ezithengiweyo eziqhelekileyo zibe yilayibrari egciniweyo yezisombululo ezigcina umgca wakho ubaleka kwaye uzinzile.
