Xa iinjineli zicacisa iintsimbi ezigayiweyo zokugalela iinxalenye zemoto, azikhethi nje izinto eziphathekayo-zibophelele ukuzinza komgangatho phantsi kwebhayisekile eshushu, ukuxhathisa ukubola kulwelo olunobundlongondlongo, kunye nokuthembeka kolwakhiwo kuxinzelelo oluyi-300+ lokusebenza. Yiyo loo nto ukukhangela kwi-a steel stainless ukugalela iinxalenye auto umzi-mveliso ngoqeqesho oluqinisekisiweyo lwe-metallurgical-hayi nje umthamo we-Foundry-wenza umahluko phakathi kokusilela kwintsimi kunye nobomi benkonzo ye-15 yeminyaka.
Kutheni "Ukuphosa" Wedwa Akwanelanga-Ingakumbi kwi-Auto-Grade Precision
Sibone iiprojekthi ezininzi kakhulu zidodobala xa ukuhanjiswa kudlula uhlolo olubonakalayo kodwa lusilele kuvavanyo loxinzelelo kwindibano yokugqibela. Oyena nobangela? Ulwakhiwo olungahambelaniyo lweenkozo ukusuka ekuqinisweni okungalawulwayo, okanye uxinzelelo olushiyekileyo olushiywe lungakhange luthintelwe phambi komatshini. Kwi-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., yonke intsimbi yokuphosa iqala nge-AMS 5387-ithobela isitokhwe ekrwada-enokulandeleka kwinani lobushushu, eqinisekisiweyo yamandla e-tensile ≥860 MPa kunye nobude ≥12% kwi-as-cast + isisombululo-imeko edibeneyo. Akukho kutshintshwa kwebhetshi. Akukho ndlela zimfutshane zomboneleli. Siqinisekisa ngokubambisana i-chemistry enyibilikayo kunye namaqabane ethu ezinto eziphathekayo ngaphambi kokuba kuqale ukugalela.
Inkqubo yethu yokuphosa isanti isebenzisa iimolds ezenziwe nge-ceramic ukuze kugqitywe umphezulu we-Ra ≤6.3 μm-eqinile ngokwaneleyo ukutsiba umatshini obunzima ebusweni obungabalulekanga. Kwiijometri ezintsonkothileyo ezifana nezindlu zepiston pump cylinder, sidibanisa utyalo-mali lwamacandelo abhityileyo eludongeni (ubukhulu bodonga ukuya kuthi ga kwi-4.5 mm) kunye nokujika okuchanekileyo kwe-CNC kunye nokusila kwangaphakathi-konke ngaphakathi kwendawo enye. Oko kudityaniswa ngokuthe nkqo kuphelisa ukukhukuliseka okuphakathi kwe-dimensional. Umthengi waseJamani usandul 'ukuxela i-99.8% isivuno sokuqala sokupasa kwi-12-part hydraulic manifold assembly-kuba i-flange face flatness (0.015 mm max deviation) kunye ne-port thread concentricity (0.02 mm TIR) yabanjwa kuzo zombini izigaba zokuphosa kunye nokugqiba.
Apho Uninzi Lwemizi-mveliso Esike Ngayo Iikona—Nendlela Esiziphepha Ngayo
Abanye abavelisi baphatha insimbi engenasici njengenkqubo yorhwebo. Bathulula, bahlukumeze, bamatshini, kwaye bathumele inqanawa. Kodwa amacandelo e-auto asebenza kakhulu afuna ngaphezulu: amazinga okupholisa alawulwayo ukukhusela ukubunjwa kwesigaba se-sigma kwi-316SS; ukuphelisa uxinzelelo *phambi* komatshini wokugqibela wokutshixa kwijometri; kunye nokuqinisekiswa kwe-GD & T esekelwe kwi-CMM kwiqashiso ngalinye-kungekhona nje iisampuli zenqaku lokuqala.
Siqhuba ii-checkpoints ezintathu ezinyanzelekileyo:
- Ukuqinisekiswa kwezinto ezingenayo nge-OES spectrometry kunye novavanyo lwe-tensile bar
- Ukuhlolwa kwenkqubo emva komatshini okhohlakeleyo usebenzisa i-Zeiss CONTURA G2 CMMs-eneengxelo ezipheleleyo ze-ASME Y14.5 zokuthobela isikhundla, iprofayili, kunye nokuphuma
- Uvavanyo lokugqibela lokusebenza: uxinzelelo lwe-hydrostatic lubambe kwi-1.5 × ilinganiswe uxinzelelo lokusebenza imizuzu engama-30, kunye nokuhlolwa kwedayi nge-ASTM E165
Oku akusiyo i-overkill-yindlela esiqinisekisa ngayo ukuba i-winch centre shaft roller yemoto ephuma kuhola wendlela isinda kwimijikelezo engama-20,000 yokulayisha okuguquguqukayo kweetoni ezili-12 ngaphandle kokuqaliswa kwe-microcrack.
UMsebenzi wokwenyani weHlabathi ufuna ukuBumba ubuKhono bethu
Amalungu ethu ensimbi engenastainless ephosa iimoto asebenza kwindawo apho ukungaphumeleli kuthetha ukuba ixesha lokuphumla lixabisa i-18,000 yeedola / ngeyure. Ke sinjineli kwezona meko zimbi kakhulu-hayi umndilili wedatha. Umzekelo:
- Iivalvu zoxinzelelo lweenkqubo zedizili ezixhaphakileyo zoxinzelelo oluphezulu zihamba ngebhayisikile eyothusayo ukusuka ku--40 ° C ukuya + 180 ° C-iqinisekisiwe ngemijikelo engama-500 ngaphambi kokuziswa.
- Iziseko zempompo zamacandelo okukhutshwa kwetyuwa emanzini olwandle zivavanyelwa ukuxhathisa emigodini ngokwe-ASTM G48 Indlela A (6% FeCl₃, iiyure ezingama-24, akukho migodi> 0.05 mm ubunzulu)
- Yonke i-T800 cobalt-based alloy castings ibandakanya ukuhlaziywa kwe-microstructure nge-SEM / EDS ukuqinisekisa ukuchithwa kwe-carbide efanayo-ibaluleke kakhulu ekukhuseleni ukunxiba kwe-abrasive kwi-slurry pump impellers.
Asihlangani nje ne-ISO 9001. Silungelelanisa inyathelo ngalinye lenkqubo kunye nemigaqo ye-SAE AS9100-nangona singenazo iziqinisekiso ze-aerospace-kuba ukhutshelo ludlulisela ngokuthe ngqo ekuthembekeni kwemoto.
Ukukhetha iqabane elilungileyo kuthetha ukubuza imibuzo echanekileyo
Ukuba uvavanya a steel stainless ukugalela iinxalenye auto umzi-mveliso, buza ezi zinto zintathu ngaphambi kokuba utyikitye i-PO:
- Ngaba unokubonelela ngokulandeleka okupheleleyo kwezinto-ukusuka kwinombolo yobushushu ukuya kwingxelo yokugqibela yovavanyo-yokuthunyelwa kwinyanga ephelileyo?
- Ngaba uyawenza umnyinyiva wokuphelisa uxinzelelo *phambi* komatshini wokugqibela? Ukuba akunjalo, uhlawula njani ukugqwetheka?
- Yeyiphi eyona nxalenye yemveliso yakho ixesha elide? Ndibonise idatha ye-CPk yemilinganiselo ebalulekileyo kwiinyanga ezintandathu.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ipapasha le datha ngenkuthalo ngexesha lophononongo lobunjineli. Siyazi ukuba intembeko ayakhelwanga kwiincwadana-ifunyanwa ngokungena elubala kwinto elinganisiweyo, ilinganiswa njani, kwaye kwenzeka ntoni xa umlinganiselo uwela ngaphandle kwemida. Ixesha lethu lokukhokela kwii-odolo zomthamo ophakathi (i-50-500 pcs) iiveki ze-14-kungekhona ngenxa yokuba sicotha, kodwa ngenxa yokuba sakha kwi-buffer yokuqinisekiswa kwe-metallurgical, kungekhona nje ukucwangciswa komatshini.
Amalungu e-auto estainless ayitshintshi. Bangabancedisi benkqubo. Kwaye intsebenzo evumela ukuba isebenze iqala kwakudala ngaphambi kokuba isikhunta sithululwe-ngenzululwazi yezinto eziphathekayo, ukuqeqeshwa kwenkqubo, kunye nokunyamezela ukunyamezela kwintelekelelo. Lo ngumgangatho esiwubambeleyo-hayi nje kwiinkcukacha zabathengi bethu, kodwa koomatshini iindawo zabo ziya kuba namandla ngomso.
