Ultrasonic welding fixture igishushanyo ntabwo kijyanye no guhinduranya icyuma kuntebe. Byerekeranye nigihe ntarengwa, ihererekanyabubasha ryingufu, hamwe nimpuhwe zumukanishi hagati yigikoresho na geometrie igice. Muri Botou Haijun Metal Products Co., Ltd., twubatsemo ibikoresho birenga 1200 byo gusudira ultrasonic yo gusudira kubakiriya mu bikoresho byimodoka, amazu yubuvuzi, hamwe nibikoresho bya elegitoroniki - buri kimwe cyemewe munsi yumutwaro nyawo, ntabwo ari CAD gusa.
Impamvu Igishushanyo mbonera gikora cyangwa kigabanya imbaraga zawe zo gusudira
Byinshi byananiranye na ultrasonic weld isubira inyuma - ntabwo ari ihembe, ntabwo ari generator. Turabibona inshuro nyinshi: umukiriya avuga imbaraga zidahuye zo gusudira, flash kumeneka, cyangwa guhindura igice. Basimbuza transducer, bongera guhindura amplitude, ndetse bahindure resin - gusa bavumbuye intandaro yicaye munsi yigice. Ibikoresho bitateguwe neza byerekana uburyo bwo kunyeganyega butagenzuwe, umuvuduko ukabije, cyangwa kugoreka ubushyuhe mugihe cyo gutura. Inzu yumukiriya wa sensor imwe yacitse kumurongo weld 37% yigihe. Ibikoresho byabo byakoreshaga isahani ya aluminiyumu idafite aho itabara. Nyuma yogushushanya shingiro hamwe no gukomera gukomeye hamwe na 0,02 mm kwihanganira-bihuye na pin ya locator, gutsindwa byagabanutse kugera kuri 0.8%.
Inzitizi zingenzi zumubiri zitwara ibyemezo byose:
Kwirinda: Ibikoresho bigomba kuguma munsi ya 5 kHz inshuro karemano kugirango wirinde guhuza hamwe na 20-40 kHz weld cycle Gukwirakwiza imbaraga: Umuvuduko ugomba kwibanda muri ± 0.3 mm yumutwe weld - ntabwo unyuze mubice byose Kwigunga: Aluminium 6061-T6 ikora kuri prototyping nkeya; ibyuma bikomeye H13 ni itegeko kuri> 50.000 cycle Amategeko atanu adashidikanywaho (Igishushanyo mbonera cy'umusaruro nyawo)
Dushyira mu bikorwa aya mategeko kuri buri gishushanyo mbonera cyo gushushanya - nta na kimwe kidasanzwe:
Shakisha mbere, kanda kabiri: Koresha ingingo eshatu za kinematike (pine ebyiri za dowel + ikibanza kimwe) mbere yo gukoresha imbaraga zose. Twapimye kugera kuri 0,15 mm ihindagurika ryuruhande rwibikoresho bifata mbere yo gushakisha - bihagije kugirango duhuze umuyobozi wa ingufu za 0.5 mm. Huza ibikoresho CTE kubice: Niba gusudira PC / ABS, irinde ibyuma bidafite ingese keretse byishyuwe. Kwiyongera k'ubushyuhe bidahuye bitera micro-guhinduranya mugihe cyizunguruka. Gukosora bisanzwe? Shyiramo 304 zidafite ingese mumibiri 6061-T6. Ntakintu kireremba hafi ya zone weld: Ubuso ubwo aribwo bwose butagira umutekano muri mm 8 zifatanije zikora nkinzira yinyeganyeza itateganijwe. Dutunganya imashini zose zimenyekanisha muburyo bumwe - ntituzongere kongeramo insimburangingo. Kwihanganira umwanya-wo kwihanganira ibintu: Ikinyuranyo cya mm 0,05 hagati yikigice nifatizo kigwira muri 0,12 mm gutandukana munsi ya 2500 N umutwaro wa clamp. Turerekana ubuso bwa mm0.01 mm hejuru yumwanya ukoreramo - kandi tukabigenzura hamwe na CMM mbere yo koherezwa. Kubona serivisi> ubwiza: Duhuza imirongo yose ya pneumatike imbere kandi dukoresha hex-urufunguzo-rushobora kwihuta-nubwo rwongera amasegonda 12 muguterana. Abatekinisiye bo mu murima basimbuza aho bambaye mumasegonda 90. Ibishushanyo "bisukuye" byabanywanyi bisaba gusenywa byuzuye no kongera guhinduka. Iyo Off-the-Shelf Ibikoresho byananiranye-nicyo wakora aho
Amakipe amwe agerageza guhagarika aluminiyumu hamwe na clamp zishobora guhinduka. Irakora -kuzunguruka 300. Noneho pin ya locator yambara, flex base yibanze, hamwe na weld ihoraho irashonga. Turakurikirana uku kubora: impuzandengo isubirwamo ni 17% by cycle 1,200 kumurongo udakomeye. Imibare irasobanutse. Kubiruka birenga 5.000, igikoresho cyihariye cya ultrasonic welding fixture igishushanyo cyishura munsi munsi ya 8 binyuze mukugabanya ibicuruzwa no kumanura.
Ariko kwihitiramo ntibisobanura kugorana. Ibikorwa byacu byiza cyane bikurikiza urwego rworoshye:
Isahani y'ibanze: Mm 40 z'ubugari bwa H13 ibyuma, ubushyuhe bukorerwa kuri 48-52 HRC, ubutaka bugera kuri mm 0.005 Sisitemu: Guhinduranya ibyuma byinjizwamo ibyuma, kanda-bikwiranye na 0.002 mm Uburyo bwo gufunga: Amashanyarazi ya pneumatike afite ibyuma bifata ibyuma-nta ntoki Gusohora igice: Spring-loaded lift pins actuated by the same air circuit as clamping Gushushanya Kwemeza Urashobora Kwizera-Ntabwo Byiringiro Byonyine
Igishushanyo ntabwo ari ikintu. Twemeza igishushanyo cyose mubice bitatu:
Ubwa mbere, isesengura ryuburyo muri SolidWorks Simulation-yemeza ko nta buryo bwumvikana buri hagati ya 15-45 kHz. Icya kabiri, kwipimisha prototype kuri Branson 2000X hamwe nibice nyabyo byakozwe hamwe na resin nyinshi. Icya gatatu, kwihutisha ibizamini byubuzima: 10,000 weld cycle kuri 120% power nominal, gupima imyambarire ya locator, gutandukana shingiro, hamwe nimbaraga zo gusudira.
Iyi nzira yafashe inenge ikomeye muburyo bwa sensor sensor yubuhinzi. Isesengura ryuburyo ryerekanaga uburyo bwa torsional kuri 32.7 kHz - muri 0.3 kHz ya 33 kHz yamahembe. Hatabayeho gukosorwa, resonance yaba yarongereye amahembe yambara kuri 4 ×. Twongeyeho imbavu ebyiri mm 8 zikomeye - zagenzuwe mugice cya kabiri cyo kugerageza. Igice cya nyuma cyatanze 99,94% umusaruro wambere-watsinze ibice 42.000.
Tangira Iburyo - Mbere yo Gukata bwa mbere
Uzane igice cyawe cyacapwe, weld igishushanyo, icyerekezo cyigihe, nubunini bwumwaka. Mu masaha 72, uzakira raporo ya DFM yerekana ibintu bikomeye: gushyira umuyobozi w'ingufu gushyira ingufu, inzibacyuho y'urukuta, hamwe nibishobora guhangayikisha. Nta kibanza cyo kugurisha. Nta nyandikorugero ya PDF. Gusa ibitekerezo bya injeniyeri byashingiwe mumyaka 14 yubukonje bukonje metallurgie no kwihanganira geometrike.
Iteraniro rya plastiki ryizewe ritangirira aho igice gihurira nicyuma. Ntabwo hamwe nibitekerezo bya software - ariko hamwe na Calibrated data ya CMM, kwisi-nyabagendwa yumuriro wisi, hamwe nibikoresho byubatswe kugirango kwihanganira bikomere kuruta inzira yawe. Nuburyo ultrasonic welding fixture igishushanyo gihagarika kuba ikiguzi-kandi kigahinduka urwego rukomeye rwo kugenzura ubuziranenge.
