Xa igcisa lomatshini libamba indawo yokuqala ku-a Itafile yokulungisa i-Bluco, ukuchaneka akulindelwanga nje-yenziwe kwi-T-slot nganye, yonke indawo yomhlaba, yonke i-micron ye-flatness. Siye sabona iivenkile zitshintsha ukusuka kwi-jigs-welded jigs ukuya kwiinkqubo ze-Bluco zemodyuli kwaye zinqumle ixesha lokuseta nge-68% ngokwe-avareji. Oko kuwisa akuyothiyori. Ilinganiselwa kwiiyure ezigcinwe ngeveki, ukuphinda kuqinisekiswe kwi-12,000+ yemijikelo yemveliso, kunye ne-zero rework kwiindibano zezibiyeli ze-aerospace ezifuna ± 0.02 mm unyamezelo lwendawo.
Kutheni "iModyuli" Ingeyiyo nje intengiso-Ilinganisiwe ukuchaneka okuphindaphindwayo
Itheyibhile yokulungisa i-Bluco inikezela ngezixhobo zelifa ezingenako: ulawulo olupheleleyo lwejometri ngaphandle kokuncama ukuguquguquka. Isiseko sayo sentsimbi sinciphisa uxinzelelo kunye nomhlaba-umhlaba ukuya ku-≤0.01 mm flatness ngaphezu kwe-1,000 × 2,000 mm. I-T-slot nganye ihambelana ne-ISO 22029 i-Class A tolerances-± 0.05 mm ububanzi, ± 0.1 mm indawo ephakathi. Oko kuhambelana kuthetha ukuba i-vise exhonywe namhlanje ibamba u-Z-ubude obufanayo ngomso, kwaye inxalenye efanayo yosapho iphinda iphinda ngaphakathi kwe-0.008 mm Cpk kwiishifti ezintathu.
Siye savavanya iikhithi zokudibanisa ezihambelana ne-Bluco ezihambelana necala kwizindlu ezifanayo ze-aluminiyam. Zimbini kuphela eziphunyeziweyo zonke amaxabiso torque ekujoliswe kuyo (18–22 N · m) ngaphandle intambo galling okanye slot deformation. Umehluko? Ukuqinisekiswa kokuqina: iqinisekisiwe i-58-62 HRC kuwo onke amaqumrhu abambezelayo, hayi nje "intsimbi eqinile." Ngaphandle kwaloo nkcazo, ukuphindaphinda kuyawa emva kwemijikelo engama-300. Uninzi lwabasebenzisi abajongi ubunzima-kodwa bayaqaphela xa imingxuma yebholithi ikhukuliseka.
Iindleko zokwenyani zokuSebenza “ngoKwaneleyo”
Abanye baphikisa ukuba iitheyibhile zeemodyuli zibiza ngaphezulu kunezilungiso ezidityanisiweyo. Yinyani. Kodwa silandele iindleko ezipheleleyo zobunini kubathengi abali-14 kwiinyanga ezili-18. Iivenkile ezisebenzisa iisistim ze-Bluco zanciphisa i-fixture-related scrap nge-41%, zanciphisa ixesha leprogram yokuseta okutsha nge-53%, kunye nokwandisa ubomi be-CNC spindle umyinge we-17%-kuba ukungcangcazela ukudambisa kuphuculwe ngokunyuka okuhambelanayo, okuqinileyo.
Indawo yokusilela efihliweyo? Isiseko sengqibelelo yezinto. Ukuxeliswa kwexabiso eliphantsi kusebenzisa intsimbi engwevu kunye nokusabalalisa i-graphite flake engahambelaniyo. Ngaphantsi kwemithwalo ephindaphindiweyo yokubopha, ii-micro-cracks zenza kufuphi ne-T-slots. Siyibonile ibangela i-0.03 mm ukuphakama kokutshintsha emva kwemijikelo ye-800. Intsimbi ye-Bluco-grade eyinyani isebenzisa ukupholisa okulawulwayo kunye ne-alloying (0.4-0.6% Cu, 0.25-0.35% Ni) ukuqinisekisa amandla afanayo okuqina ≥250 MPa kunye nokumelana nempembelelo> 12 J kwi-−20 ° C. Ayisiyiyo ubunjineli obugqithisileyo-ithintela ukumangala kolungelelwaniso lwangoMvulo kusasa.
Yintoni Esebenzayo Kwimveliso Yemihla Ngemihla—Hayi Iincwadana Ezinemifanekiso
Iimpawu ezintathu zahlula ukuhambelana kwe-Bluco eqinisekisiweyo kwithiyori yendawo yokubonisa:
Slot indexing ukuphinda-phinda: Yonke i-100 mm T-slot centerline iqinisekisiwe nge-laser tracker-kungekhona i-calipers. Ukutenxa kuhlala ngaphantsi kwe-±0.015 mm ngaphaya kwe-3 m. Ukugcinwa komphezulu ophantsi: Emva kweeyure ze-1,500 ze-machining eqhubekayo (iitshiphu zentsimbi, ukuvezwa kwe-coolant, ukusula yonke imihla), uburhabaxa bomphezulu buhlala bu-Ra ≤0.8 µm-akukho kupolishwa kuyadingeka. Ijometri yojongano lweClam-to-slot: I-Chamfer angle ibanjwe kwi-30 ° ± 0.5 °, i-radius ≤0.2 mm. Oku kuphelisa ukubopha ngexesha lokuqinisa i-torque ephezulu kwaye iqinisekisa ukudibanisa okupheleleyo kwimicu yokuqala ye-3. Sakhe sabukela umthengisi weemoto we-Tier-1 wala ukuthunyelwa ngenxa yokuba umatshini wabo wokulinganisa ulungelelanisa i-0.022 mm ye-offset kwindawo ye-datum B. Unobangela weengcambu? Umzimba wokubamba osele ugugile one-0.04 mm enxitywa egxalabeni lawo. Batshintshela kumacandelo aqinisekisiweyo e-Bluco-kwaye badlulisa ukuhlolwa kwenqaku lokuqala kwindlela elandelayo.
Ukukhetha Okulungileyo Kuthetha Ukubuza Imibuzo Efanelekileyo
Ngaphambi koku-odola itafile yokulungisa iBluco-okanye nayiphi na inkqubo ebanga ukuhambelana kweBluco-buza ezi zinto zintathu:
Ngaba ungabonelela ngengxelo yovavanyo lokusila yesiseko sokugalela, ukuquka ukomelela, ubulukhuni, kunye nokwakheka kweekhemikhali? Ngaba iziqhoboshi zakho zibandakanya amaxwebhu anokulandeleka wonyango lobushushu-hayi nje "ukuphathwa ubushushu" -kunye nokufundwa kwe-Rockwell C-scale kumanqaku amathathu kwindawo nganye? Ngaba ukucaba kuqinisekisiwe ngokwe-ISO 10360-2 kusetyenziswa i-CMM elungisiweyo, eneziphumo ezilandelekayo kwimigangatho ye-NIST? Ukuba iimpendulo azicacanga, zilibazisekile, okanye azikho—hamba. Ukusebenza ngokuchanekileyo akukho malunga nobuhle. Imalunga nolawulo olubhaliweyo, oluphindaphindwayo, olunokuphicothwa. I-Botou Haijun Metal Products Co., Ltd. yenza amacandelo asetyenziswa kwiinkqubo ezidityanisiweyo ze-Bluco kubathengi kulo lonke elaseMntla Melika naseYurophu-kungekhona njengomthengisi, kodwa njengeqabane lobunjineli bokwakha iinxalenye kwezo zichanekileyo. Indawo yabo ehambelana ne-ISO iqinisekisa yonke ibhetshi ngokuchasene nezatifiketi eziphathekayo ezingenayo, yenza i-CMM yenkqubo yokuhlola kumanqanaba abalulekileyo, kunye neenqanawa ezineengxelo ezipheleleyo-kungekhona izishwankathelo.
A Itafile yokulungisa i-Bluco ifumana ixabiso layo hayi xa ifika, kodwa xa inxalenye ye-50 efanayo iphuma kumatshini-i-ruout efanayo, ukuphela komhlaba okufanayo, ukuzithemba okufanayo. Oko kuthembeka kuqala nge-metallurgy, kuqhubeka nge-metrology, kwaye iphela kuphela xa inxalenye idibana noshicilelo. Nantoni na encinci ayichanekanga. Lithemba elinxibe intsimbi.
