Uyilo lwe-welding ye-ultrasonic alukho malunga nokubopha isinyithi kwibhentshi. Kumalunga nokuchaneka kwexesha, ukuhanjiswa kwamandla okulawulwayo, kunye novelwano lomatshini phakathi kwesixhobo kunye nejometri. E-Botou Haijun Metal Products Co., Ltd., sakhe ngaphezulu kwe-1,200 yezixhobo ze-ultrasonic ze-welding kubathengi kwi-automotive trim, izindlu zezixhobo zonyango, kunye ne-electronics yabathengi-nganye iqinisekisiwe phantsi kwemithwalo yokwenyani yemveliso, kungekhona nje ukulinganisa kwe-CAD.
Kutheni i-Fixture Design yenza okanye iphule amandla akho e-Weld
Uninzi lwee-welds ze-ultrasonic ezisileleyo zibuyela emva kwindawo-hayi uphondo, hayi ijenereyitha. Siyibona ngokuphindaphindiweyo: umthengi uxela amandla e-weld angahambelaniyo, ukuvuza kwe-flash, okanye inxalenye yokuguqulwa. Bathatha indawo ye-transducer, bahlengahlengisa ubude, bade batshintshe iiresin-kuphela ukufumanisa unobangela ohleli ngaphantsi kwendawo. Isixhobo esiyilwe kakuhle sazisa iindlela zokungcangcazela ezingalawulekiyo, uxinzelelo olubambekayo olungalinganiyo, okanye ukuphazamiseka kobushushu ngexesha lokuhlala. Izindlu zomxhasi omnye zaqhekeka kumgca we-weld 37% yexesha. Ukulungiswa kwabo kusetyenziswa iipleyiti ze-aluminiyam ezisicaba ezingenazo iindawo zokukhulula. Emva kokuyila ngokutsha isiseko ngokuqina kokuqina kwendawo kunye nezikhonkwane ze-locator ezihambelana nokunyamezela kwe-0.02 mm, ukungaphumeleli kwehle ukuya kwi-0.8%.
Imiqobo ephambili yomzimba iqhuba zonke izigqibo:
Ukuphepha i-resonance: Ukulungiswa kufuneka kuhlale ngaphantsi kwe-5 kHz ukuphindaphinda kwendalo ukuthintela ukudibanisa kunye nomjikelo we-weld we-20-40 kHz Ukuhanjiswa kwamandla okubamba: Uxinzelelo kufuneka lugxininise ngaphakathi kwe ± 0.3 mm yejoyinti ye weld-hayi kuyo yonke indawo yonyawo Ukwahlukaniswa kweThermal: I-Aluminiyam 6061-T6 isebenza kwiprototyping ephantsi komjikelo; intsimbi eqinile i-H13 inyanzelekile kwi->50,000 imijikelezo Imithetho emihlanu yoyilo engaxoxisiyo (ukusuka kwimigangatho yoMveliso yokwenyani)
Sinyanzelisa le mithetho kulo lonke uphononongo lomzobo-akukho ngaphandle:
Khangela kuqala, bambe okwesibini: Sebenzisa ukunyuswa kwekinematic ngamanqaku amathathu (izikhonkwane ezimbini zedowel + enye indawo) phambi kokuba usebenzise nawaphi na amandla okubamba. Silinganise ukuya kuthi ga kwi-0.15 mm ye-lateral shift kwi-fixtures ebambayo ngaphambi kokufumana indawo-eyanele ukungahambi kakuhle umlawuli wamandla we-0.5 mm. Tshatisa imathiriyeli ye-CTE nenxalenye: Ukuba i-welding PC / ABS, gwema iziseko zensimbi ezingenasici ngaphandle kokuba uhlawule. Ukungahambelani kokwandiswa kwe-Thermal kubangela utshintsho oluncinci ngexesha lokuphindaphinda imijikelo. Ukulungiswa kwethu okusemgangathweni? I-Inlay 304 iindawo ezingenasici kwimizimba ye-anodized 6061-T6. Akukho zinto zidadayo kufutshane nendawo yeweld: Nayiphi na indawo engakhuselekanga ngaphakathi kwe-8 mm yokudibanisa isebenza njengendlela yokungcangcazela engalindelekanga. Sisebenza ngomatshini zonke iindawo zokukhangela indawo ngokuseta enye-ungaze wongeze izinto ezifakwe emva komatshini. Ukunyamezelana kwexesha lokuhlala imicimbi: Umsantsa oyi-0.05 mm phakathi kwenxalenye kunye nesiseko solungiso uphindaphindeka ube yi-0.12 mm yokuphambuka phantsi kwe-2,500 N yomthwalo wokubamba. Sicacisa ukukhanya komhlaba ≤0.01 mm ngaphezu kwendawo esebenzayo-kwaye siqinisekise nge-CMM ngaphambi kokuthunyelwa. Ufikelelo lwenkonzo > ubuhle: Sihambisa yonke imigca ye-pneumatic ngaphakathi kwaye sisebenzisa i-hex-key-i-fasteners efikelelekayo-nokuba yongeza imizuzwana ye-12 kwindibano. Amagcisa omsebenzi athatha indawo yeendawo ezigugileyo ngaphantsi kwemizuzwana engama-90. Uyilo "lococekileyo" lwabakhuphisana lufuna ukuchithwa okupheleleyo kunye nokulinganisa kwakhona. Xa izilungiso ezingaphandle kweShelf zisilela-kwaye kufuneka wenze ntoni endaweni yoko
Amanye amaqela azama iibhloko ze-aluminiyam eziqhelekileyo ezineeclamps ezihlengahlengiswayo. Iyasebenza-kwimijikelo engama-300. Emva koko izikhonkwane ze-locator ziyanxiba, i-base flexes, kunye ne-weld consistency erodes. Silandelela oku kubola: ilahleko eyi-avareji yokuphinda-phinda yi-17% ngomjikelo we-1,200 kwizinto ezingaqiniwanga. Izibalo zicacile. Ukuqhuba ngaphezulu kweeyunithi ezingama-5,000, uyilo lwe-ultrasonic welding yesiko luhlawula ngaphantsi kweeshifti ezisi-8 ngokuncipha kwenkunkuma kunye nexesha lokuphumla.
Kodwa ukwenza ngokwezifiso akuthethi ubunzima. Olona lungiso lusebenzayo lulandela uluhlu olulula lwemigangatho:
Isiseko sepleyiti: I-40 mm ubukhulu bentsimbi ye-H13, iphathwe ngobushushu ukuya kwi-48-52 HRC, i-flat flat ukuya kwi-0.005 mm Inkqubo yokukhangela indawo: Ukufakwa kwentsimbi eguquguqukayo eqinileyo, i-press-fit kunye nokuphazamiseka kwe-0.002 mm Indlela yokubambelela: Iisilinda ze-pneumatic ezine-position sensors-akukho i-levers manual Ukukhutshwa kwenxalenye: Izikhonkwane zokuphakamisa ezilayishwe entwasahlobo eziqhutywe yisekethe yomoya efanayo njenge-clamping Ukuqinisekiswa koyilo onokuthi ukuthembe-hayi nje ngethemba
Umzobo awungomdlalo. Siqinisekisa uyilo ngalunye kwizigaba ezithathu:
Okokuqala, uhlalutyo lwe-modal kwi-SolidWorks Simulation-ukuqinisekisa ukuba akukho ndlela ye-resonant ikhona phakathi kwe-15-45 kHz. Okwesibini, uvavanyo lweprototype kwi-Branson 2000X yethu kunye neendawo zokwenyani zemveliso kunye ne-resin lots. Okwesithathu, uvavanyo lobomi olukhawulezileyo: i-10,000 lemijikelo ye-weld kwi-120% yamandla aqhelekileyo, ukunxitywa kwendawo yokulinganisa, ukuphambuka kwesiseko, kunye nokuyeka ukomelela kwe-weld shear.
Le nkqubo ibambe isiphene esibalulekileyo kugcino lwesivamvo senzwa yezolimo yakutsha nje. Uhlalutyo lwe-modal lubonise imo ye-torsional kwi-32.7 kHz-ngaphakathi kwe-0.3 kHz ye-33 kHz ye-horn frequency. Ngaphandle kokulungiswa, i-resonance yayiza kwandisa i-tip ye-tip nge-4 ×. Songeze iimbambo ezimbini ze-8 mm zokuqina-ziqinisekisiwe kwisigaba sesibini sokuvavanya. Umdlalo wokugqibela unikezele nge-99.94% isivuno sempumelelo yokuqala kwiiyunithi ezingama-42,000.
Qala Ekunene—Ngaphambi Kokusika Okokuqala
Siphathele inxalenye yakho yokuprinta, i-weld joint sketch, ixesha elijoliswe kuko lomjikelo, kunye nomthamo wonyaka. Kwiiyure ezingama-72, uya kufumana ingxelo ye-DFM eqaqambisa iimpawu ezibalulekileyo zokulungisa: ukubekwa komlawuli wamandla, uguquko lobunzima bodonga, kunye nezigxininisi ezinokubakho zoxinzelelo. Akukho ndawo yokuthengisa. Akukho template yePDF. Ingxelo yobunjineli nje esekelwe kwiminyaka eli-14 yokwenziwa kwesinyithi esibandayo kunye nolawulo lokunyamezelana kwejometri.
Indibano yeplastiki ethembekileyo iqala apho inxalenye idibana nesinyithi. Akunjalo ngeengqikelelo zesoftware-kodwa ngedatha yeCMM elinganisiweyo, ukukhwela ibhayisekile kwehlabathi lokwenyani, kunye nezixhobo ezakhelwe ukubamba unyamezelo olungqongqo kunenkqubo yakho yokubumba. Yiloo ndlela uyilo lwe-ultrasonic welding fixture iyeka ukuba liziko leendleko-kwaye iba ngumaleko wakho owomeleleyo wokulawula umgangatho.
