Iworkshop nganye echanekileyo ijongene nomqobo omnye othuleyo: itafile engaphantsi kwendawo yokusebenza. Hayi nje nawuphi na umphezulu-kodwa a itheyibhile yokwenza isiko yenzelwe ukubamba unyamezelo, ifunxe ukungcangcazela, izixhobo ze-ankile, kwaye isinde kunxibelelwano lwemihla ngemihla lwesinyithi-kwintsimbi. Siye sabona abaqhubi be-CNC bephinda besebenza kabini ngenxa yokuba itafile itshintshile phantsi koxinzelelo. Siye sabukela izibiyeli ezisikiwe ze-laser zisilela kuvavanyo olusebenzayo emva kokuphazamiseka kwe-weld-zilandelelwe emva kokwandiswa kwe-thermal engalinganiyo kwi-plate yesiseko se-off-spec. Ezi ayizizo iimeko ezinzima. Ngamanqaku eengxabano zemihla ngemihla atshabalalisa ukuphinda-phinda, anyuse amaxabiso ezinto ezilahliweyo, kwaye alibazise ukuvunywa kwenqaku lokuqala.
Kutheni iitafile ezingaphandle kweShelf zisilela phantsi komthwalo wokwenyani weworkshop
Iibhentshi zentsimbi ezisemgangathweni zikhangeleka zirhabaxa ude uzilayishe nge-40-kg yee-chassis ezitsalwa kubunzulu okanye usebenzise amandla okugoba eetoni ezili-12 kumgama oziimitha eziyi-1.2. Emva koko i-warping iqala-ingabonakali, kodwa kwii-microns. Ukuphambuka kwe-0.08 mm ekupheleni kwetafile ye-1,500 mm iguqulela kwi-±0.15 ° impazamo ye-angular kwi-welded subassembly. Oko kwanele ukulungelelanisa imingxuma yokukhwela ngokungafanelekanga kwiibhloko zevalvu yehydraulic okanye ukulahla iindlela zetotshi zokutshisela iirobhothi.
Silinganisa oku ngokwesiqhelo. Kolunye ungqinisiso lwakutsha nje kumxhasi wenkqubo yezolimo, iitafile ezintathu ezifanayo ngaphandle kweshelufu-nganye inikwe i-1,000 kg yomthwalo omileyo-ibonise i-0.23 mm, 0.31 mm, kunye ne-0.47 mm i-sag phantsi kwe-uniform 800 kg yokulayisha. Akukho namnye owadibana ne-±0.05 mm yonyamezelo olufunekayo kwijigi yabo yokutsibela isibiyeli. Oyena nobangela? Izithuba zembambo ezingalinganiyo, ubukhulu bepleyiti obungahambelaniyo, kunye namandla esivuno angangqinisiswanga kwizinto ezisisiseko.
Yinyani itheyibhile yokwenza isiko ayiqali ngemilinganiselo-kodwa ngefiziksi yesicelo. Yintoni eyona torque yokuqina? Mangaphi amanqaku omdlalo afuna ufakelo lwe-M10 olunemisonto echanekileyo nge-0.02 mm yokunyamezela indawo? Ngaba ujongano lwetafile kunye nengalo yeCMM okanye idibanisa iilocators zomoya? Ezi zichaza ulwakhiwo—kungekhona ngenye indlela.
Izinto ezine ezingaxoxisiyo kubuNjineli beTheyibhile echanekileyo
Ngokusekwe ngaphezulu kwe-1,200 yeetafile ezakhiweyo ukusukela ngo-2016, sikwahlulahlula oko kwahlula ukusebenza okuphindaphindwayo kuphinda kusetyenziswe ixabiso:
Ukuqinisekiswa kwezinto eziphathekayo: Akukho ngxelo yovavanyo lokusila? Akukho ukwakha. I-Cold-rolled Q235B kunye ne-S355JR iipleyiti kufuneka zibonise amandla aqinisekisiweyo aqinisekisiweyo (≥470 MPa), i-elongation (≥22%), kunye nobunzima (120-160 HB). I-Aluminium 6061-T6 idinga ubungqina be-T6 ye-tender-iqinisekiswe yi-Rockwell B-scale test ngaphambi kokuba machining. Uyilo oludambisa uxinzelelo: Zonke iiplati ezisisiseko zifumana ukunyanzeliswa kwe-thermal kwi-620 ° C kwiiyure ze-4, zilandelwa ukupholisa okulawulwayo. Ukutsiba eli nyathelo kumema ukucotha ngexesha lemveliso emide-ingakumbi ibaluleke kakhulu kwiitafile ezibambe uhlengahlengiso lokuhlola i-multi-axis. Ukuqiniswa kwendawo: Ijiyometri yembambo ayilungelelananga-ifakwe kwimephu. Imimandla yomthwalo ophezulu ifumana iimbambo ezithe tye kunye nobukhulu besiseko se-12-mm; iindawo ezinoxinzelelo oluphantsi zisebenzisa i-6-mm iimbambo ezibekwe kumaziko angama-250 mm. Siqinisekisa lonke uyilo ngohlalutyo lwe-FEA buckling pre-weld. Ukunyamezela ukupakisha ulawulo: Ufakelo olunemisonto alucinezeleki. Ziyi-helicoil-efakwe kwi-remed, i-counterbored imingxuma-enokunyamezela isikhundla esibanjwe kwi-± 0.015 mm nge-CNC jig boring. Umphezulu othe tyaba uqinisekiswa kwinqwelomoya yereferensi yegranite kusetyenziswa isalathisi sokucofa kunye ne-master straightedge-hayi inqanaba lomoya. Indlela iBatch encinci yokuguquguquka iqhuba i-ROI yokwenyani
Iivenkile ezininzi zicinga ukuba iitafile zesiko zifuna ii-MOQ eziphezulu kunye namaxesha okukhokela iiveki ezili-12. Iphelelwe lixesha. E-Botou Haijun Metal Products Co., Ltd., sakha iitheyibhile zeprototype yeyunithi enye kwiintsuku ze-11 zokusebenza-kuquka uphononongo olupheleleyo lwe-DFM, ukuqinisekiswa kwezinto eziphathekayo, kunye nokuhlolwa kokugqibela kwe-CMM. Ngoba? Kuba indawo yethu ethobela i-ISO idibanisa isitampu, ukugoba, ukuwelda, kunye nomatshini ochanekileyo phantsi kophahla olunye. Akukho bathengisi bangaphandle. Akukho kulibaziseka kwesandla. Akukho lunyamezelo luqokelelweyo phakathi kwababoneleli.
Olu lawulo luthe nkqo luzisa iziphumo ezinokulinganiswa: Umboneleli weemoto omnye weNqanaba loku-1 unciphise ixesha lomjikelo wendibano yesibiyeli nge-22% emva kokutshintsha kwiitafile ze-aluminiyam zemodyuli ukuya kwitafile yethu eyenziwe ngentsimbi edityanisiweyo enezibambo ezidityanisiweyo zepneumatic kunye nezikhonkwane zedatum. Omnye umxhasi unqumle ixesha lokuvunywa kwenqaku lokuqala ukusuka kwiintsuku ezili-17 ukuya kwiintsuku ezi-4-kuba itheyibhile yabo entsha ibambe ii-callouts ze-GD&T kuzo zonke izinto ezibaluleke kakhulu ezili-14 ngaphandle kokuqaqamba okuphindayo.
Iindleko zihlala ziyinkxalabo esebenzayo-kodwa ukuyijonga kakubi kuyabiza. Itheyibhile ye-$4,200 yesiko ehambisa i-0.02 mm ukuphindaphinda ihlawula emva kweenyanga ezi-3.2 xa isusa isiganeko esinye seveki esichithwa kwi-avareji ye-$ 1,350 emsebenzini kunye nempahla. Ezinye iindlela ezingaphandle kweshelufu azifane zizise loo ROI. Barhweba ukonga kwangaphambili kutsalwa ofihlakeleyo wokusebenza.
Yintoni ekufuneka uyenzile kwiTheyibhile yakho elandelayo yokuFakela isiNtu—Hayi nje
Itafile yakho akufuneki "ibambe iinxalenye." Kufuneka ixhase iinjongo zakho zenkqubo. Buza le mibuzo ngaphambi kokuba ucaphule:
Ngaba iyaziqinisa iijigs zakho ezikhoyo-okanye ifuna ukuyilwa ngokutsha zonke izixhobo? Ngaba umphezulu wayo ungamelana ne-MIG ye-welding spatter ngaphandle kokubeka esichengeni ukucaba? Ngaba ukuhanjiswa kobunzima bayo kulungiselelwe ukulinganisa umthwalo womgangatho wakho-okanye ngaba kuya kufuna ukuqiniswa kolwakhiwo?
Ngaba imingxuma enyukayo imiselwe ukufikelela kwi-CMM probe yakho-okanye uya kuphulukana ne-30% yokhuseleko lomlinganiselo? Ukuba iimpendulo zifuna ukucinga, awukakulungeli ukwakha. Qala ngemodeli yeCAD-kwaye uyithumele kubunjineli. I-Botou Haijun Metal Products Co., Ltd. ibonelela ngempendulo ye-DFM yasimahla phakathi kweentsuku ezintathu zokusebenza. Akukho ndawo yokuthengisa. Akukho kugcinwa kwesango. Igalelo elinokusetyenzwa nje: ungazongeza phi iimbambo, zeziphi izixhobo ezinqanda ukubola kwegalvanic kunye nezixhobo zakho ezingenasici, indlela yokulandelelanisa i-welds ukunciphisa ukugqwetheka.
A itheyibhile yokwenza isiko sisiseko sokuchaneka—kungekhona ukucinga emva koko. Kulapho ukunyamezelana kuqala khona, kungekhona apho kuphelela khona. Xa itheyibhile yakho ibambe inyaniso, yonke into esezantsi ihambelana. Xa kungenjalo, akukho nto enye ibalulekileyo.
