ULungiso lwe-3D oluShicileleyo lwe-Welding: Ukuchaneka, uLondolozo lweendleko kunye nokuChwetheza ngokuKhawuleza 

I-3D eprintiweyo ye-welding fixtures iguqula indlela abavelisi ababamba ngayo, balungelelanise, kwaye baphinde baphinde i-welds-ingakumbi kwimveliso ephantsi ukuya kwi-middle-volume. Silubonile olu tshintsho ngokwethu: umboneleli woomatshini bezolimo weNqanaba loku-1 unciphise ixesha lokuhamba ukusuka kwiintsuku ezingama-22 ukuya kwiiyure ezingama-48. Umhlanganisi wepakethi yebhetri ye-EV yaseNyakatho yaseMelika unciphise ixabiso le-fixture nganye nge-68% ngelixa uphucula ukuphindaphinda ukuya kwi-± 0.15 mm. Ezi ayizizo iimeko ezinzima. Ziyisiphumo esithe ngqo sokusebenzisa Izixhobo ze-welding eziprintiweyo ze-3D njengomsebenzi osebenzayo, othwala umthwalo-kungekhona nje izinto ezibonakalayo.

Ukuchaneka akubingelelwa-Kuye kwaHlaziywa ngokutsha

Abaninzi bacinga ukuba ukuveliswa okongeziweyo kuthetha ukuthotyelwa. Hayi apha. Xa sivavanya uhlengahlengiso lwe-fused deposition modeling (FDM) olwenziwe nge-ULTEM 9085 kunye ne-carbon-fiber-reinforced PEEK ngokuchasene noomatshini bomatshini be-aluminium, iziphumo zothuse neqela lethu le-metrology. Ngaphantsi kwe-80 kg ye-clamping force kwi-120 ° C, inguqulo ye-3D eprintiweyo ibambe ukuzinza kwendawo ngaphakathi kwe-± 0.08 mm ngaphezu kwemijikelezo ye-500-ehambelana ne-coefficient yokwandiswa kwe-thermal ye-aluminium ngokusondeleyo kunokuba kulindelwe. Ngoba? Kuba ukuchaneka kuqala ngejiyometri eyakhiwe ngenjongo. Sizinzisa imiphezulu yedatum ngokuthe ngqo kwifayile yoshicilelo. Silungelelanisa iimpawu ukunciphisa impazamo yokupakishwa kwe-Z-axis. Songeza iimbambo zokuqiniswa kwendawo apho i-pneumatic clamps ifaka i-torque-akukho post-machining efunekayo.

Oko kwahlukile kwizixhobo zemveli. Izilungiso ezingoomatshini zihlala zifuna ukubengezela okuphindaphindayo okanye ukukrwela ngesandla ukubetha ii-callouts ze-GD&T. Ngezixhobo ze-welding eziprintiweyo ze-3D, ukunyamezela ukupakishwa kwedijithali kuqala: imodeli ye-CAD → i-STL eqinisekisiweyo → inxalenye eprintiweyo → ingxelo eqinisekisiweyo ye-CMM. Sihambisa oko kulandeleka ngokupheleleyo-iingxelo zokuhlola ezinobungakanani, ii-ID zempahla, kunye nembali ye-thermal logs-kunye nayo yonke into ethunyelwayo.

Ugcino lweendleko luvela kuMqukuqelo woMsebenzi, hayi nje izinto eziphathekayo

Ayisiyiyo malunga neplastiki ngokuchasene nentsimbi. Kumalunga nokuphelisa amanyathelo amathandathu angenaxabiso: ukulibaziseka kokucaphula, ukuvunywa komzobo, ukucwangciswa kweCNC, ixesha lokuseta, ukuphinda kuhlolwe inqaku lokuqala, kunye nokugcinwa kwentloko. Omnye umthengi utshintshe iijigi ezili-17 zelifa leemodyuli ezintathu eziprintiweyo ze-3D ezisisiseko kunye nokufakwa kwendawo etshintshanayo. Uhlahlo lwabiwo-mali lwabo lonyaka lwezixhobo zehla ukusuka kwi-$ 142,000 ukuya kwi-$ 31,000-kwaye utshintsho lobunjineli ngoku luthatha iintsuku ze-1.5 endaweni ye-11.

Nantsi eyona nto ishukumisa inaliti:

Silandelela i-ROI yehlabathi yokwenyani kwiiprojekthi ezingama-89. Intlawulo ephakathi: iinyanga ezi-3.2. Ukukhawuleza: Iintsuku ze-11-xa isixhobo sokwakha saseJamani i-OEM yachitha i-$ 210,000 kwiipalethi ze-welding eziphelelwe lixesha emva kokuqinisekisa iindlela ezimbini eziprintiweyo.

I-Prototyping eKhawulezayo ithetha ukuWelding Ngokwenene-Akukokuhlekisa nje

"Iprototyping ekhawulezayo" iyasilela xa iprototype ingakwazi ukumelana ne-spatter, ukuvezwa kwe-UV, okanye ukuphinda ibhayisekile okubambezelayo. Asishicileli iimodeli "ezibonakala ngathi". Siprinta izixhobo “ezifana nomsebenzi” ezakhelwe i-arc flash, i-slag adhesion, kunye nokufikelela kwitotshi yerobhothi. Ulwakhiwo lwethu olusemgangathweni lusebenzisa iipholima ezikwaziyo ukumelana nobushushu, ezikwaziyo ukumelana nobushushu ezibekwe kwinkonzo eqhubekayo ye-180°C. Ukusetyenziswa komgangatho ophezulu, sidibanisa izikhonkwane zokubeka intsimbi, imikhono eqinile yentsimbi, kunye neendawo zokudibanisa ezenziwe nge-ceramic-zonke zifakwe ngexesha lokushicilela.

Oku kuvala umsantsa phakathi kwenjongo yoyilo kunye nenyani yomgangatho wevenkile. Xa umxhasi wenkqubo esezantsi yemoto esithumelele indibano yesibiyeli enemiqobo yokufikelela kwi-weld eqinile, siprinte izinto ezintathu ezahlukeneyo ngobusuku nje obunye: enye inofikelelo oluphezulu, enye ineendlela zetotshi ezigobileyo, enye ineendlela ezidityanisiweyo zokucoca igesi. Lonke uphononongo lwe-DFM oluphumeleleyo kwi-CAD, zonke zidityaniswe ngokungenasiphako kumgca wazo okhoyo we-MIG. Akukho kuhlelwa ngokutsha. Akukho zixhobo zitsha. Ukuqinisekiswa ngokukhawuleza-kunye neendawo ezilahliweyo zero.

IBotou Haijun Ihambisa Oko Abanye Bakuthembisayo

I-Botou Haijun Metal Products Co., Ltd. ayikhupheli ngaphandle uyilo lwayo okanye ushicilelo. Singabanikazi balo lonke ikhonkco: ukusuka kuphononongo lokuqala lwe-GD&T kunye nokulinganisa uxinzelelo lobushushu ukuya kuqinisekiso lokugqibela lweCMM kunye nokuthunyelwa ngamaxwebhu ahambelana ne-ISO. Indawo yethu ekwisiXeko saseBotou iqhuba abashicileli abaqinisekisiweyo bomgangatho wemizi-mveliso ecaleni koomatshini bokushicilela be-CNC kunye neeseli ze-welding ezizenzekelayo-ngoko sivavanya izixhobo eziphantsi komthwalo wokwenyani wemveliso, hayi iimeko zelebhu.

Sisebenzela abathengi abafuna ngaphezulu kwefayile-to-fixture umthengisi. Bafuna umntu osiqondayo isizathu sokuba i-± 0.05 mm locator offset ibangele ukungaphumeleli kwe-root fusion kwi-welds ye-stainless tube welds. Ngubani owaziyo ukuba intsimbi efakwe i-zinc ichaphazela njani ukunamathela kwepolymer ngexesha lokubamba. Ngubani olandelela ukusebenza kwentsimi-hayi nje amazinga okupasa amanqaku okuqala.

Ukuba uyaphonononga Izixhobo ze-welding eziprintiweyo ze-3D, buza le mibuzo ngaphambi kokubeka iodolo yakho yokuqala: Ngaba umthengisi uqinisekisa ukuphazamiseka kwe-thermal kwiqondo lokushisa lokusebenza? Ngaba banokubonelela ngesiqinisekiso semathiriyeli esihambelana neemfuno zakho zophicotho lwangaphakathi? Ngaba banikezela ngeengxelo ezinobungakanani obubotshelelwe kwiidatha zakho zangaphambili zeCAD? Ukuba impendulo ngu “hayi” kuyo nayiphi na—qhubeka ujonge.

Ixesha elizayo alikho amalungu ashicilelweyo athatha indawo yezixhobo zentsimbi. Kubukrelekrele, ukubamba okuthe ngqo kwesicelo okukhawulezisa ukuphindaphinda ngaphandle kokuncama ingqibelelo ye-weld. Lo ngumgangatho esiwakhela kuwo-kwaye siwuthumele usuka ku-https://www.haijunmetals.com.
