Idizayini ye-welding ye-Ultrasonic ayimayelana nokubhowula insimbi ebhentshini. Kumayelana nesikhathi esinembayo, ukudluliswa kwamandla okulawulwayo, nozwela lwemishini phakathi kwethuluzi kanye nengxenye yejometri. E-Botou Haijun Metal Products Co., Ltd., sakhe izinto zokushisela ze-ultrasonic ngokwezifiso ezingaphezu kuka-1,200 zamaklayenti ekunqumeni kwezimoto, izindlu zemishini yezokwelapha, nezinto zikagesi ezithengwayo—ngasinye siqinisekiswa ngaphansi kwemithwalo yangempela yokukhiqiza, hhayi nje ukulingiswa kwe-CAD.
Kungani I-Fixture Design Ikwenza Noma Yephula Amandla Akho Weld
Ama-welds amaningi e-ultrasonic ahlulekile abuyela emuva ku-fixture-hhayi uphondo, hhayi i-generator. Siyibona ngokuphindaphindiwe: ikhasimende libika amandla e-weld angahambisani, ukuvuza kwe-flash, noma ingxenye yokuguqulwa. Zithatha indawo ye-transducer, zilinganise kabusha ubukhulu, zishintshe ngisho nezinhlaka—ukuphela kwento ebangela imbangela ehlala ngaphansi kwengxenye. Isakhiwo esiklanywe kabi sethula izindlela zokudlidliza ezingalawuleki, ingcindezi yokubopha engalingani, noma ukuhlanekezela okushisayo ngesikhathi sokuhlala. Izindlu zezinzwa zeklayenti elilodwa ziqhekeke kulayini we-weld 37% wesikhathi. Indawo yabo isebenzise amapuleti e-aluminium ayisicaba angenazo izindawo zokusiza. Ngemva kokuklama kabusha isisekelo ngokushuna kokuqina kwendawo kanye nezikhonkwane zendawo ezivumelana nokubekezelela okungu-0.02 mm, ukwehluleka kwehle kwafika ku-0.8%.
Izithiyo zomzimba ezibalulekile ziqhuba zonke izinqumo:
Ukugwema i-resonance: Ukulungiswa kufanele kuhlale ngaphansi kuka-5 kHz imvamisa yemvelo ukuvimbela ukuhlangana nomjikelezo wokushisela ongu-20–40 kHz Ukusatshalaliswa kwe-clamp force: Ingcindezi kufanele igxile ngaphakathi kuka ±0.3 mm wejoyinti lokushisela—hhayi kuyo yonke ingxenye yonyawo Ukuhlukaniswa okushisayo: I-Aluminium 6061-T6 isebenza nge-prototyping yomjikelezo ophansi; insimbi eqinile i-H13 iyimpoqo emijikelezweni engu-50,000 Imithetho Emihlanu Yedizayini Engaxoxiswana (Kusuka Ezitezini Zokukhiqiza Zangempela)
Sisebenzisa le mithetho kukho konke ukubuyekezwa kwemidwebo—akukho okuhlukile:
Thola kuqala, qinisa okwesibili: Sebenzisa ukukhwezwa kwe-kinematic okunamaphuzu amathathu (izikhonkwane ezimbili zedowel + indawo eyodwa) ngaphambi kokusebenzisa noma yimaphi amandla okubamba. Silinganisele ukufika ku-0.15 mm ushintsho olungemuva ezimpahleni ezibambayo ngaphambi kokuthola indawo—okwanele ukumisa kabi umqondisi wamandla ongu-0.5 mm. Qondanisa okubalulekile kwe-CTE nengxenye: Uma i-PC/ABS yokushisela, gwema izisekelo zensimbi engagqwali ngaphandle kokuthi unxeshezelwe. Ukungezwani kokwanda kokushisa kubangela ukushintshashintsha okuncane phakathi nemijikelezo ephindaphindiwe. Ukulungiswa kwethu okujwayelekile? I-Inlay 304 izindawo ezingenasici emizimbeni ye-anodized 6061-T6. Azikho izici ezintantayo eduze nendawo yokushisela: Noma iyiphi indawo engavikelekile engaphakathi kuka-8 mm wejoyinti isebenza njengendlela yokudlidliza okungahlosiwe. Sisebenza ngomshini zonke izindawo zokuthola indawo ngokusetha okukodwa—asilokothi sengeze okokufaka ngemva komshini. Indaba yokubekezelelana kwesikhathi sokuhlala: Igebe elingu-0.05 mm phakathi kwengxenye nesisekelo sendawo liphindaphinda libe ukuchezuka okungu-0.12 mm ngaphansi komthwalo wokubopha ongu-2,500 N. Sicacisa ukucaba kwendawo ≤0.01 mm endaweni esebenzayo—futhi siqinisekise nge-CMM ngaphambi kokuthunyelwa. Ukufinyelela isevisi > ubuhle: Sihambisa yonke imigqa ye-pneumatic ngaphakathi futhi sisebenzisa izixhumi ezifinyelelekayo ze-hex-key-ngisho noma ingeza amasekhondi angu-12 ekuhlanganiseni. Ochwepheshe basezindaweni bashintsha izindawo ezigugile ngaphansi kwamasekhondi angu-90. Imiklamo “ehlanzekile” yabancintisana nabo idinga ukuhlakazwa okuphelele nokulinganiswa kabusha. Lapho Ukulungiswa Kwe-off-the-Shelf Kuhluleka-nokuthi Yini Okufanele Uyenze Kunalokho
Amanye amaqembu azama amabhulokhi e-aluminium ajwayelekile anama-clamp alungisekayo. Isebenza-imijikelezo engama-300. Khona-ke izikhonkwane ze-locator ziyaguga, ama-base flexes, futhi ukuguquguquka kwe-weld kuyaguguleka. Silandelela lokhu kubola: ukulahlekelwa okuphindaphindekayo okumaphakathi ngu-17% ngomjikelezo ongu-1,200 kuzinto ezingaqinile. Izibalo zicacile. Isebenza ngaphezu kwamayunithi angu-5,000, idizayini ye-welding ye-ultrasonic yangokwezifiso ibuyisela emuva ngaphansi kwamashifu angu-8 ngokusebenzisa izinsimbi ezincishisiwe kanye nesikhathi sokuphumula.
Kodwa ukwenza ngokwezifiso akusho ubunzima. Ukulungiswa kwethu okusebenzayo kakhulu kulandela ukulandelana okulula:
Ipuleti eliyisisekelo: Insimbi engu-40 mm ugqinsi H13, ifakwe ngokushisa ibe ngu-48–52 HRC, iphansi ibe yi-0.005 mm Isistimu yendawo: Izinsimbi eziqinile ezishintshashintshayo, cindezela-zilingana nokuphazanyiswa okungu-0.002 mm I-clamping mechanism: Amasilinda we-pneumatic anezinzwa zokuma—awekho ama-lever manual Ukukhishwa kwengxenye: Izikhonkwane zokuphakamisa ezilayishwe intwasahlobo eziqhutshwa yisekethe yomoya efanayo nokubopha Ukuqinisekiswa Kwedizayini Ongakwethemba-Hhayi Ithemba Nje
Umdwebo awuyona into. Siqinisekisa wonke umklamo ngezigaba ezintathu:
Okokuqala, ukuhlaziywa kwe-modal ku-SolidWorks Simulation—ukuqinisekisa ukuthi ayikho imodi ezwakalayo ekhona phakathi kuka-15–45 kHz. Okwesibili, ukuhlolwa kwe-prototype ku-Branson 2000X yethu enezingxenye zangempela zokukhiqiza kanye nenkatho ye-resin. Okwesithathu, ukuhlolwa kwempilo okusheshisiwe: imijikelezo ye-weld engu-10,000 ku-120% wamandla ajwayelekile, ukugqokwa kwendawo yokulinganisa, ukuchezuka kwesisekelo, nokwehla kwamandla e-weld shear.
Le nqubo ibambe iphutha elibalulekile kuhlu lwakamuva lwabakaki benzwa yezolimo. Ukuhlaziywa kwe-modal kumake imodi ye-torsional ku-32.7 kHz—ngaphakathi kuka-0.3 kHz wefrikhwensi yophondo engu-33 kHz. Ngaphandle kokulungiswa, i-resonance izobe ikhulise ukugqokwa kwethiphu yophondo ngo-4×. Sengeze izimbambo ezimbili eziqinile ze-8 mm-eziqinisekiswe esigabeni sesibili sokuhlolwa. Umdlalo wokugcina ulethe isivuno sokuphasa sokuqala esingu-99.94% kumayunithi angama-42,000.
Qala Kwesokudla—Ngaphambi Kokunquma Kokuqala
Silethele ingxenye yakho yokuphrinta, i-weld joint sketch, isikhathi esiqondiwe somjikelezo, kanye nevolumu yonyaka. Emahoreni angu-72, uzothola umbiko we-DFM ogqamisa izici ezibalulekile zokulungisa: ukubekwa komqondisi wamandla, ukuguquguquka kokuqina kodonga, kanye nezinto ezigxilisa ingcindezi ezingase zibe khona. Ayikho intengo yokuthengisa. Awekho ama-PDF esifanekiso. Impendulo nje yobunjiniyela isekelwe eminyakeni engu-14 yokuphatha i-metallurgy ebandayo kanye nokuphathwa kokubekezelelana kwejometri.
Umhlangano wepulasitiki othembekile uqala lapho ingxenye ihlangana nensimbi. Hhayi ngokuqagela kwesoftware—kodwa ngedatha ye-CMM elinganiselwe, ukuhamba ngebhayisikili okushisayo komhlaba wangempela, nezakhiwo ezakhelwe ukubamba ukubekezelelana kuqine kunenqubo yakho yokubumba. Yileyo ndlela i-ultrasonic welding fixture design eyeka ngayo ukuba isikhungo sezindleko—futhi iba isendlalelo sakho sokulawula ikhwalithi esiqine kakhulu.
