Yintoni i-Ultrasonic Welding

I-Ultrasonic welding yinkqubo yoshishino apho i-high-frequency ultrasonic acoustic vibrations isetyenziswa ekuhlaleni kwiindawo zokusebenza ezibanjwe kunye phantsi koxinzelelo lokudala i-weld-state weld.Isetyenziswa ngokuqhelekileyo kwiiplastiki kunye neentsimbi, kwaye ngakumbi ukudibanisa izinto ezahlukeneyo.Kwi-welding ye-ultrasonic, azikho iibholiti ezidibeneyo, izikhonkwane, izinto ezithengiswayo, okanye i-adhesives eyimfuneko ukubopha izinto kunye.Xa ifakwe kwisinyithi, uphawu oluphawulekayo lwale ndlela kukuba iqondo lobushushu lihlala ngaphantsi kwendawo yokunyibilika yezinto ezibandakanyekayo ngaloo ndlela kuthintela naziphi na iimpawu ezingafunekiyo ezinokuvela kubushushu obuphezulu bezinto eziphathekayo.

Ukudibanisa iinaliti eziyinkimbinkimbi ezibunjiweyo ze-thermoplastic, izixhobo zokuwelda ze-ultrasonic zinokwenziwa ngokulula ukuze zilingane neenkcukacha zamalungu adityanisiweyo.Amacandelo afakwe phakathi kwendlwane emisekileyo (i-anvil) kunye ne-sonotrode (uphondo) exhunywe kwi-transducer, kunye ne-~20 kHz i-low-amplitude acoustic vibration ikhutshwa.(Qaphela: Iifrikhwensi eziqhelekileyo ezisetyenziswa kwi-ultrasonic welding of thermoplastics yi-15 kHz, 20 kHz, 30 kHz, 35 kHz, 40 kHz kunye ne-70 kHz).Xa iiplastiki ze-welding, i-interface yamacandelo amabini ilungiselelwe ngokukodwa ukugxininisa inkqubo yokunyibilika.Enye yemathiriyeli ihlala ine-spiked okanye umlawuli wamandla ajikelezileyo onxibelelana nenxalenye yesibini yeplastiki.Amandla e-ultrasonic anyibilikisa uqhagamshelwano lwamanqaku phakathi kwamalungu, ukudala ukudibanisa.Le nkqubo yindlela efanelekileyo yokuzenzekelayo kwi-glue, izikrufu okanye uyilo lwe-snap-fit.Idla ngokusetyenziswa namalungu amancinane (umzekelo, iiselfowuni, izixhobo zombane ezisetyenziswayo, izixhobo zonyango ezilahlwayo, izinto zokudlala, njl. njl.) kodwa inokusetyenziswa kwiindawo ezinkulu njengeqela elincinane lesixhobo semoto.I-Ultrasonics ingasetyenziselwa ukuwelda isinyithi, kodwa iqhelekile kwiiweld ezincinci zesinyithi ezithambileyo, ezithambileyo, umz. i-aluminiyam, ubhedu, i-nickel.I-Ultrasonics ayinakusetyenziswa ekudibaniseni i-chassis yemoto okanye kwi-welding amaqhekeza ebhayisikile kunye, ngenxa yamanqanaba ombane afunekayo.

I-Ultrasonic welding ye-thermoplastics ibangela ukunyibilika kwendawo yeplastiki ngenxa yokufunxa amandla okungcangcazela ecaleni kwejoyini ukuze idityaniswe.Kwizinyithi, i-welding yenzeke ngenxa yokusasazwa koxinzelelo oluphezulu lwe-oxides yomhlaba kunye nokuhamba kwendawo yezinto.Nangona kukho ukufudumeza, akwanele ukunyibilikisa izinto ezisisiseko.

I-Ultrasonic welding ingasetyenziselwa zombini iiplastiki ezinzima kunye nezithambileyo, ezifana neeplastiki ze-semicrystalline, kunye neentsimbi.Ukuqonda i-ultrasonic welding kuye kwanda ngophando kunye novavanyo.Ukuveliswa kwezixhobo eziphucukileyo nezingabizi kakhulu kunye nokunyuka kwemfuno yeplastiki kunye nezixhobo ze-elektroniki kukhokelele kulwazi olukhulayo lwenkqubo esisiseko.Nangona kunjalo, imiba emininzi ye-ultrasonic welding isafuna uphononongo olungakumbi, olufana nomgangatho we-weld ukusetyenzwa kweeparamitha.I-ultrasonic welding iyaqhubeka ibe yintsimi ekhula ngokukhawuleza.
