Xa iinjineli zicacisa ukuchithwa kwesanti kwiindawo zetsimbi eziphezulu-ingakumbi kwiinkqubo ze-hydraulic, izixhobo ze-oyile kunye negesi, okanye iindibano zempompo ezinzima-ayikhethi nje inkqubo. Bakhetha iqabane eliqondayo indlela ukwakhiwa kweenkozo ezichaphazela ngayo ubomi bokudinwa, indlela ukubumbana kwe-mold kuphembelela ukuphindaphinda kwe-dimensional, kwaye kutheni ukunyamezela kwe-0.15 mm kwi-cobalt-alloy cylinder housing ayisosicelo-yinto engaxoxisanayo yokusebenza imfuneko. Kulapho amava ehlabathi lokwenyani ahlula ababoneleli abanakho kwinyani imveliso yesanti yokugalela amaqabane.
Kutheni iSand Casting isaphumelela kwiMishini-Amacandelo abalulekileyo kuShishino
Abanye bacinga ukuba ukugaywa kwesanti kokwezicelo zelifa. Kodwa siye sayibona inika impumelelo ephindaphindiweyo apho ezinye iinkqubo zisilela: i-iron castings yecandelo elikhulu elifuna ukuxhathisa ukothuka kwe-thermal kwiziseko zempompo; izindlu zentsimbi ezinemijelo yokupholisa yangaphakathi engenakwenzeka umatshini we-post-cast; izinto ezingenastainless ezifuna amandla e-isotropic kuwo wonke amacandelo ashinyeneyo. Isitshixo kukulawula-kungekhona ngaphezulu kokugalela ubushushu okanye ixesha lokushukuma, kodwa kulo lonke ikhonkco: ukuhambelana kwesanti eluhlaza, ulungelelwaniso loshicilelo olungundoqo, uyilo lwesango lokuhamba kwe-laminar, kunye nemijikelo yokuphoswa koxinzelelo lwasemva koxinzelelo olungqinisiswe yimephu yegeji yoxinzelelo.
Kwenye iprojekthi yakutshanje, i-OEM yaseYurophu idinga imizimba yevalvu yoxinzelelo engama-42 kwi-ASTM A351 CF8M. Umthengisi wabo wangaphambili uphose i-callouts ye-GD&T kwimingxunya emithathu yeflange exhomayo-ebangela ukuphazamiseka kwendibano kuvavanyo lokugqibela. Siyibambe ngexesha lokuqinisekiswa komzobo, silungelelanise i-angle yokuyila i-angle ye-cope nge-0.8 °, kwaye songeza i-pin yokulungelelanisa i-mold. Isiphumo: Azikho ukusebenza kwakhona kwiiyunithi ezili-120. Loo nqanaba lokungenelela alinakwenzeka ngaphandle kokuhlanganiswa okuthe nkqo-ukusuka kumxube wesanti ukuya kwi-CNC yokugqiba umatshini kumgangatho ofanayo.
Apho Ubuchwephesha bezinto eziphathekayo budibana nenkqubo yoqeqesho
Iialloyi ze-cobalt-nickel ezifana ne-AMS 5387 kunye ne-T800 aziphenduli kwiinkqubo zokwenziwa kofuzo. Indawo yabo ephezulu yokunyibilika, ubumanzi obuphantsi, kunye nenkangeleko eshushu yokukrazula ifuna iindlela ezilungelelanisiweyo: imilinganiselo eqiniweyo ye-binder, ukungunda okufudunyeziweyo ngaphezulu kwe-250 ° C, kunye namazinga okupholisa alawulwayo abekwe esweni kusetyenziswa i-thermocouples efakwe ngaphakathi. Sigalele ngaphezulu kwe-1,700 kg ye-T800 kwiinyanga ezili-18 ezidlulileyo-kwaye ibhetshi nganye ithwala ukulandeleka okugcweleyo: inani lobushushu, ingxelo yohlahlelo lwe-spectrographic, kunye ne-as-cast microstructure iifoto ezibonisa isithuba sengalo ye-dendrite ngaphantsi kwe-25 µm.
Olo qeqesho ludlulela ngaphaya kokuphathwa kwengxubevange. Ukuphoswa kwentsimbi esetyenziselwa ubunjineli bemoto yewinch kwishaft rollers, siqinisekisa ukubalwa kwamaqhuqhuva egraphite (ASTM E2567) kunye nomlinganiselo weferrite/pearlite *phambi kokuba * machining aqale. Ngoba? Ngenxa yokuba i-5% ye-pearlite engaphezulu yokwandisa ixesha lokusila nge-37% kwaye inciphisa ubomi besixhobo kwisiqingatha. Siyayilinganisa—asiyiqikelela.
“Ukuchaneka” Kuthetha ntoni Enyanisweni xa Uziqhelanisa
Ukuchaneka ekujuleni kwesanti akukho malunga nokusukela ukunyamezelana kwinqanaba le-micron kwiindawo ezinkulu. Imalunga nokuqikelela. Ikhono lethu eliqhelekileyo: ± 0.3 mm kwiimpawu ukuya kwi-600 mm, ± 0.5 mm kwiindawo ezingaphezu kwe-1,200 mm-kunye neengxelo zenqaku lokuqala eziqinisekisiweyo ze-CMM zibandakanyiwe ngaphandle kweendleko ezongezelelweyo. Kodwa eyona nto ixabiseke kakhulu luphawu lwethu lwengxelo: ukuba umzobo wakho ufuna i-12.5 µm Ra igqibezele kumbhobho owenziwe ngoomatshini, siya kuhlaba umkhosi ukuba indawo yokuphosa iya kufuna i-2.1 mm okanye 3.4 mm yokususwa kwesitokhwe-kwaye ukuba oku kuchaphazela njani ukucutheka kwesibonelelo kunye nokubekwa kwesinyusi.
- Iivalve zoxinzelelo: I-GD&T-indawo yokuhlala ehambelanayo, ingqinwe ngegaging yomoya kunye nokuvuza-kuvavanywa kwi-1.5 × uxinzelelo lokusebenza
- Izindlu zempompo zempompo yepiston: Ubunzulu bobunzulu obugcinwe kwi-0.025 mm TIR ngaphaya kwe-450 mm ubude
- Imilomo yealloyi ye-cobalt engeyiyo eyomgangatho: Ukuguquguquka kobukhulu bodonga kulawulwa ngaphakathi kwe-±0.18 mm kumacandelo abuncinane be-8 mm
Asikuthathi ukuphosa kunye noomatshini njengamasebe ahlukeneyo. Ziyizigaba ezilandelelanayo zenkqubo enye-ngoko umdwelisi we-CNC uphonononga i-CT scan ngaphambi kokubhala indlela yokuqala yesixhobo. Yiloo ndlela ukuphepha ngayo ukufumana i-porosity phantsi komhlaba obalulekileyo emva kweeyure ze-14 zokugaya.
Ukukhetha Iqabane Eliza Kuhambisa Iqabane—kungekhona Nje Izithembiso
A imveliso yesanti yokugalela kufuneka uphendule imibuzo emithathu phambi kokuba usayine i-PO: Ngaba banokubamba unyamezelo lwakho oluqinileyo kweyona jiyometri inzima *kwimveliso*, hayi kwiprototype nje? Ngaba banazo iziqinisekiso zabo eziphathekayo-okanye baxhomekeke kumaphepha omthengisi? Kwaye xa kukho ukutenxa kwe-dimensional, ngaba bayabelana ngedatha yengcambu (iinqobo zesanti yokungena, i-curves yohlalutyo lokunyibilika, iimephu ze-X-reyi) okanye bakhuphe ifom yesenzo sokulungisa?
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza phantsi kwe-ISO 9001:2015 enemigaqo yokuhlola ebhaliweyo kuyo yonke iqashiso lokuphosa. Yonke impahla ekrwada iqinisekisiwe, yonke indawo ephathwe ubushushu ifakiwe, yonke into egqityiweyo ihlolwe ngokubonakalayo phantsi kwe-10× yokukhulisa. Sisebenzela abathengi kuMntla Melika, eYurophu, nakuMzantsi-mpuma we-Asia-kungekhona ngabarhwebi, kodwa ngencoko yobunjineli ngokuthe ngqo: Ukutolika kwe-GD&T, ingxelo yokwenziwa kokwenziwa ngaphakathi kweeyure ezingama-48, kunye nohlaziyo lwemveliso yeveki kunye nobungqina befoto beziganeko eziphambili.
Ikamva lokugaywa kwesanti echanekileyo ilele kwi-workflows ye-hybridi-apho ukuphosa kuchaza isambuku sejometri kunye nokunyaniseka, kunye nomatshini wokuhambisa umphezulu osebenzayo kunye nokulingana okuqinileyo. Oko kufuna ingqiqo enzulu ye-metallurgical, ukudibanisa inkqubo engqongqo, kunye nonyamezelo lweziro kwiingqikelelo. Ukuba iprojekthi yakho elandelayo ifuna iinxalenye ezenzayo-ezingafanelanga nje-qala ngokucaca kwenkqubo, hayi nje ukucaphula ixabiso.
