Ngokuthandwa kobuchwepheshe bokushisela,igagasi le-ultrasoniciye yasungulwa njengendlela entsha yokushisela, enezinzuzo ezingenakuqhathaniswa ekushiseleni izinsimbi ezifanayo noma ezihlukene.Ngenxa yokuthi i-ultrasonic non-metallic welding ayidingi i-flux nemithombo yokushisa yangaphandle, isakhiwo esishiselwe ngeke sikhubazwe ukushisa futhi ngeke kube khona ukucindezeleka okusalayo.
Isingeniso se-Ultrasonic welding technology
Ukushisa kwe-ultrasonicukusetshenziswa kwegagasi lokudlidliza kwefrikhwensi ephezulu edluliselwe ebusweni bezinto ezimbili ezizoshiselwa, esimweni sokucindezela, ukuze izinto ezimbili zingqubuzane phezulu kanye nokwakheka kokuhlangana phakathi kwezingqimba zamangqamuzana.Izingxenye eziyinhloko zesethi yeuhlelo lwe-welding lwe-ultrasonichlanganisagenerator ultrasonic, i-ultrasonic transducer, i-ultrasonic flange, uphondo lwe-ultrasonic, isikhunta kanye nomzimba womshini we-ultrasonic.
Isimiso sokushisela i-ultrasonic
Umgomo we-ultrasonic welding welding: isenzo se-ultrasonic endaweni yokuxhumana yepulasitiki ye-thermoplastic, izokhiqiza amashumi ezinkulungwane zezikhathi zokudlidliza kwe-high-frequency ngomzuzwana, lokhu kufinyelela ku-amplitude ethile yokudlidliza kwe-high-frequency, amandla e-ultrasonic adluliselwa ku-welding. endaweni, ngoba indawo Welding kuyinto ezimbili Welding interface at ukumelana umsindo, ngakho izoveza izinga lokushisa eliphezulu wendawo.
Futhi ngenxa yokungabi bikho kokushisa okushisayo kwepulasitiki, ayikwazi ukusatshalaliswa ngesikhathi, iqoqwe endaweni yokushisela, okuholela ekuncibilikeni okusheshayo kobuso bokuxhumana bamapulasitiki amabili, kanye nokucindezela okuthile, ukuze ihlanganiswe ibe yinye. .Lapho i-ultrasonic iyeka ukusebenza, vumela ingcindezi iqhubeke imizuzwana embalwa ukuze iqine, yakhe uchungechunge oluqinile lwama-molecule angashiselelwa ngamandla asondelene nalawo ezinto ezingavuthiwe.
Izinga le-ultrasound welding plastic lincike ku-amplitude yekhanda le-welding ye-transducer, ingcindezi eyengeziwe kanye nesikhathi sokushisela nezinye izici ezintathu, isikhathi sokushisela kanye nokucindezela kwekhanda le-welding kungashintshwa, i-amplitude inqunywa i-transducer kanye nenduku ye-amplitude.
Kunevelu efanelekile yokusebenzisana kwalawa manani amathathu.Lapho amandla edlula inani elifanele, inani elincibilikayo lepulasitiki lizoba likhulu futhi impahla yokushisela kulula ukuyikhubaza.Uma amandla amancane, akulula ukushisela, ukucindezela okungeziwe akukwazi ukuba kukhulu kakhulu.Le ngcindezi enkulu ingumkhiqizo wobude bonqenqema bengxenye eshiselwe kanye nengcindezi enkulu nge-1mm yonqenqema.
Isimiso sokushisela insimbi ye-ultrasonic: Umgomo we-ultrasonic metal welding kuyindlela ekhethekile yokuxhuma izinsimbi ezifanayo noma ezingafani ngokusebenzisa amandla okudlidliza omshini we-ultrasonic frequency (ngaphezu kuka-16KHz).I-Metal in welding ye-ultrasonic, noma ukudluliswa kwamanje ku-workpiece, noma i-workpiece ingaphansi komthombo wokushisa ophezulu, kodwa ngaphansi kwengcindezi eqinile, amandla okudlidliza ohlaka angena emsebenzini wokungqubuzana phakathi kwe-workpiece, amandla okuguqula nokukhuphuka okulinganiselwe kwezinga lokushisa. .
Isibopho se-Metallurgical phakathi kwamalunga wukushisela kwesimo esiqinile ngaphandle kokuncibilika kwesisekelo sensimbi.Ngakho-ke, ingakwazi ukunqoba ngempumelelo i-spatter kanye ne-oxidation ebangelwa ukumelana nokushisela.Umshini wokushisela we-Ultrasonic ungasetshenziselwa i-single point welding, i-multi point welding kanye ne-short strip welding yethusi, isiliva, i-aluminium, i-nickel nezinye izintambo zensimbi ezingenayo insimbi noma izinto zeshidi elincane.Ingasetshenziswa kabanzi ekushiseleni umthofu olawulwa yi-silicon, ucezu lwe-fuse, ukuhola kagesi, ucezu lwesigxobo sebhethri ye-lithium kanye nendlebe yesigxobo.
Inqubo ye-welding ye-ultrasonic
1) Indlela yokushisela: nge-ultrasound high frequency vibration welding head ngaphansi kwengcindezi emaphakathi, yenza izingcezu ezimbili zokushisa okuhlangene kwepulasitiki okuhlanganayo kanye nokuncibilika kweso, amandla okushisela angafaniswa ne-ontology, amukele izinto zobuciko ezifanele kanye ne-interface design enengqondo, ingafinyelela. ingangeni manzi futhi ingangeni moya, futhi ISEBENZISA i-AIDS ukuphazamiseka kokukhansela, ukushisela okuhlanzekile okuhlanzekile.
2) Umumo: ufana nendlela ye-maohan, le ndlela izoba yi-concave shape welding head pressure in the plastic outer ring, i-sonic welding hair surplus ngemva kokudlidliza kwe-ultra-high izoncibilika futhi ihlanganiswe nepulasitiki ezintweni zensimbi okufanele zilungiswe, futhi ibushelelezi. nokubukeka okuhle, le ndlela isetshenziswa ku-electronics, uphondo lwesimo esinqunyiwe, nezimonyo ze-lens ezihleliwe, njll.
3) I-Heat staking: ngokudluliswa kwekhanda lokushisela kanye nokucindezela okufanele, izingxenye zensimbi (njengamantongomane, izikulufu, njll.) zicindezela emgodini wepulasitiki ogodliwe futhi zimiswe ekujuleni okuthile.Ngemuva kokuqedwa, ukungezwani kanye ne-torque kungaqhathaniswa namandla okwakhiwa kwesikhunta sendabuko, okungagwema amaphutha okulimala kwesikhunta somjovo kanye nomjovo ongasheshi.
4) I-riveting welding: indlela yokushisela i-riveting ibhekisela ekudlidlizeni kwekhanda le-welding ukucindezela ukuphuma kwento ukuze ukuncibilika okushisayo kube yisimo se-rivet, ukuze izinto ezimbili zibe riveting.
I-5) I-Spot Welding: I-Spot Welding ibhekisela ekushiseni kwephuzu lezinto okungekho lula ukuklama umugqa wokushisela, okungase futhi kufinyelele umphumela wokushisela.
Impahla efanelekile yokushisela i-ultrasonic
1. I-Ultrasonic welding ifaneleka kuwo wonke ama-thermoplastics, ama-amorphous plastics afana ne-ABS,PMMA,PC,PS;Amapulasitiki angama-semi-crystalline afana ne-PA, i-PET, i-CA, i-POM, i-PE ne-PP.
2. I-Ultrasonic welding ibuye ifanele izindwangu ezingezona zendwangu, njengezindwangu ze-thermoplastic, izinto ze-polymeric, iphepha eliboshwe kanye nezindwangu ezixutshwe.
Ingxenye elandelayo sizokukhombisa umshini wokushisela we-ultrasonic welding impahla esetshenziswa kabanzi kanye ne-ultrasonic welding welding interface design kanye nezinkambu zohlelo lokusebenza, uma unentshisekelo kubo, sicela usilandele.
Sikhethekile ekukhiqizeni umshini we-welding we-ultrasonic, umshini we-welding we-high frequency, i-generator ye-ultrasonic, umshini wokushisela insimbi, umshini wokushisela ngokwezifiso, njll. Uma udinga ukwazi noma yini mayelana nobuchwepheshe be-ultrasound, sicela ukhululeke ukuxhumana nathi.
