Ultrasonic welding fixture dhizaini haisi yekusungirira simbi kubhenji. Iri nezve chaiyo nguva, inodzorwa simba rekufambisa, uye mechaniki tsitsi pakati pekushandisa uye chikamu geometry. KuBotou Haijun Metal Products Co., Ltd., takavaka anopfuura zviuru zana nemazana maviri emagetsi ekugadzira magadzirirwo evatengi mumotokari trim, dzimba dzemidziyo yekurapa, uye zvemagetsi zvevatengi - chimwe nechimwe chakasimbiswa pasi pemitoro chaiyo yekugadzira, kwete kungofananidza neCAD.
Nei Fixture Dhizaini Inogadzira kana Kutyora Weld Yako Simba
Mazhinji akakundikana ma ultrasonic welds anoteedzera kumashure kune chigadziriso-kwete nyanga, kwete jenareta. Isu tinozviona kakawanda: mutengi anoshuma zvisingaenderane weld simba, flash leakage, kana chikamu deformation. Ivo vanotsiva transducer, kudzokorora amplitude, kunyange kushandura resin-kungoziva chete chikonzero chinogara pasi pechikamu. Chimiro chisina kunyatsogadzirwa chinounza isingadzoreki mamodhi ekudengenyeka, kusaenzana kwekumanikidza, kana kukanganiswa kwemafuta panguva yekugara. Imwe mutengi sensor imba yakatsemuka pamutsetse we weld 37% yenguva. Chimiro chavo chakashandisa flat aluminium mahwendefa asina nzvimbo dzekuyamura. Mushure mekugadzira patsva hwaro nekuomarara kwenzvimbo uye 0.02 mm kushivirira-inofananidzwa nepini yelocator, kutadza kwakadzikira kusvika 0.8%.
Zvinetso zvakakosha zvemuviri zvinotungamira sarudzo dzese:
Resonance avoidance: Fixtures dzinofanirwa kugara pasi pe5 kHz natural frequency kudzivirira kubatana ne 20–40 kHz weld cycle. Kugovera simba reclamp: Kudzvanya kunofanirwa kutarisisa mukati me ± 0.3 mm yejoin ye weld-kwete kuyambuka chikamu chese chetsoka Kuzviparadzanisa nevamwe: Aluminium 6061-T6 inoshanda kune yakaderera-kutenderera prototyping; simbi yakaoma H13 inosungirwa kune> 50,000 cycles Mitemo Mishanu Isingawirirane Yedhizaini (Kubva Pamitambo Yekugadzira Yechokwadi)
Isu tinosimbisa iyi mitemo pane yega yega dhizaini yekudhirowa - hapana kunze:
Tsvaga chekutanga, sunga chechipiri: Shandisa matatu-point kinematic mounting (mbiri dowel pini + one slot) usati waisa chero clamping simba. Isu takayera kusvika pa 0.15 mm lateral shanduko muzvigadziriso zvinosungirira tisati tawana-zvakakwana kusaisa 0.5 mm simba director. Matanidza zvinhu CTE kune chikamu: Kana welding PC/ABS, dzivisa zvigadziko zvesimbi zvisina tsvina kunze kwekunge wabhadharwa. Kupisa kwekuwedzera kusawirirana kunokonzeresa micro-shift panguva inodzokororwa kutenderera. Yedu chiyero kugadzirisa? Inlay 304 nzvimbo dzisina tsvina mune anodized 6061-T6 miviri. Hapana zvinhu zvinoyangarara padyo nenzvimbo yeweld: Chero nzvimbo isina kuchengetedzwa mukati me8 mm yejoinhi inoita senzira isingatarisirwe yekudengenyeka. Isu tinochina ese nzvimbo dzelocator mune imwe chete set-usambowedzera inoisa post-machining. Kugara-nguva kushivirira stacking zvinhu: A 0.05 mm gap pakati pechikamu uye chigadziko chekugadzirisa chinowanda kuita 0.12 mm kutsauka pasi pe2,500 N clamp load. Isu tinotsanangura kudzika kwepasi ≤0.01 mm pamusoro penzvimbo inoshanda-uye simbisa iyo neCMM isati yatumirwa. Kuwana sevhisi > aesthetics: Isu tinofambisa mitsara yese yepneumatic mukati uye tinoshandisa hex-kiyi-inosvikika fasteners-kunyangwe ikawedzera masekonzi gumi nemaviri pakuungana. Nyanzvi dzemumunda dzinotsiva nzvimbo dzakasakara mukati memasekonzi makumi mapfumbamwe. Magadzirirwo emakwikwi e "akachena" anoda disassembly yakazara uye kugadzirisa zvakare. Kana Zvirongwa Zvekunze-paSherufu Zvikatadza—uye Zvekuita Pane kudaro
Zvimwe zvikwata zvinoedza generic aluminum blocks ane ma clamps anogadzirika. Inoshanda-ye300 cycles. Ipapo mapini elocator anopfeka, base inochinjika, uye weld consistency inoparadza. Isu tinoteedzera kuora uku: avhareji yekudzokororwa kurasikirwa ndeye 17% nekutenderera 1,200 pane zvisina kuomeswa zvigadziriso. Masvomhu akajeka. Kune inomhanya pamusoro pe5,000 mayunitsi, tsika ye ultrasonic welding fixture dhizaini inobhadhara kumashure pasi pemashifiti masere kuburikidza neyakaderedzwa zvimedu uye downtime.
Asi kugadzirisa hakurevi kuoma. Zvigadziriso zvedu zvinonyanya kushanda zvinotevera zviri nyore hierarchy:
Base plate: 40 mm gobvu H13 simbi, inopisa-yakagadziriswa kusvika 48-52 HRC, pasi sandara kusvika 0.005 mm Locator system: Inochinjika yakaomeswa simbi inopinza, press-fit ne 0.002 mm kupindira Clamping mechanism: Pneumatic cylinders ane position sensors-hapana manual levers Chikamu ejection: Chitubu-akatakura mapini ekusimudza anofambiswa neiyo yakafanana mhepo saiti se clamping Dhizaini Yekusimbisa Iwe Unogona Kuvimba-Kwete Kungotarisira
Kudhirowa haisi gadziriso. Isu tinosimbisa dhizaini yega yega muzvikamu zvitatu:
Kutanga, kuongorora modal muSolidWorks Simulation-kusimbisa kuti hapana resonant mode iripo pakati pe15-45 kHz. Chechipiri, prototype kuyedza pane yedu Branson 2000X ine chaiyo yekugadzira zvikamu uye resin mijenya. Chechitatu, kukurumidza kuyedza hupenyu: zviuru gumi zveweld kutenderera pa120% simba rezita, kuyera locator kupfeka, base deflection, uye weld shear simba rekudonha.
Kuita uku kwakabata chikanganiso chakakosha mune ichangoburwa sensor bracket fixture. Ongororo yeModal yakaratidza torsional mode pa32.7 kHz-mukati me0.3 kHz ye33 kHz nyanga frequency. Pasina kururamisa, resonance ingadai yakasimudza nyanga tip kupfeka ne4 ×. Takawedzera maviri 8 mm mbabvu dzakaomeswa-yakasimbiswa muchikamu chechipiri chekuyedzwa. Mutambo wekupedzisira wakaunza 99.94% yekutanga-pass goho pamayuniti makumi mana nemaviri.
Tanga Kurudyi—Usati Wacheka Kwokutanga
Huya nesu chikamu chako chakadhindwa, weld joint sketch, kutenderera nguva chinangwa, uye vhoriyamu yegore. Mukati memaawa makumi manomwe nemaviri, uchagashira rondedzero yeDFM inoratidzira zvimisikidzo-akakosha maficha: simba director director kuiswa, kukora kwemadziro shanduko, uye zvinogona kukonzeresa kushushikana. Hapana nzvimbo yekutengesa. Hapana template maPDF. Ingori mhinduro yeinjiniya yakavakirwa mumakore gumi nemana ekutonhora-ekugadzira simbi uye geometric kushivirira manejimendi.
Gungano repurasitiki rakavimbika rinotanga apo chikamu chinosangana nesimbi. Kwete nefungidziro yesoftware-asi neyakaomeswa CMM data, chaiyo-yenyika inopisa bhasikoro, uye zvigadziriso zvakavakwa kuti zvibate kushivirira zvakanyanya kupfuura maitiro ako ekuumba. Ndiyo nzira iyo ultrasonic welding fixture dhizaini inomira kuve nzvimbo inodhura-uye inova yako yakasimba yemhando yekudzora dhizaini.
