Txoj Cai Ntawm Ultrasonic Vuam Tshuab
Lub hauv paus ntsiab lus ntawm ultrasonic yas vuam: Thaum ultrasonic nthwv dej ua rau ntawm qhov chaw sib cuag ntawm cov thermoplastics, kev vibrations siab ntawm kaum tawm txhiab zaus ib ob yuav raug tsim tawm. Qhov no high-frequency kev co nrog ib tug tej yam amplitude kis ultrasonic zog mus rau lub vuam cheeb tsam los ntawm lub qaum weldment. Vim qhov loj acoustic tsis kam nyob rau hauv lub vuam cheeb tsam, uas yog, qhov sib txuas ntawm ob qhov chaw vuam, lub zos kub yuav raug generated, thiab vim cov thermal conductivity tsis zoo ntawm cov yas, nws yuav tsis tau dissipated nyob rau hauv lub sij hawm, thiab nws sib sau. nyob rau hauv welding cheeb tsam, uas ua rau lub melting sai sai ntawm qhov sib cuag ntawm ob lub plastics, ntxiv ib tug tej yam siab. thiab ces merged rau hauv ib tug. Thaum lub ultrasonic yoj tsis ua hauj lwm, cia lub siab mus ntxiv rau ob peb feeb kom nws solidify thiab tsim ib tug khoom molecular saw, thiaj li mus cuag lub hom phiaj ntawm vuam, thiab vuam lub zog yuav nyob ze rau lub zog ntawm cov ntaub ntawv raw.
Ultrasonic vuam txheej txheem:
1. Vuam Vuam yog hais txog lub pob tw vuam ntawm cov khoom yas. Kev tsim ntawm ob qhov chaw sib koom ua ke tseem ceeb heev kom tau txais cov txiaj ntsig zoo tshaj plaws. Kev siv ntau yam qauv yog nyob ntawm ntau yam, xws li hom yas, ib feem geometry thiab vuam yuav tsum tau (xws li tack, lub zog foob, thiab lwm yam).
2. Insertion Insertion yog ib txoj hauv kev los ntxig cov khoom hlau hauv cov khoom siv thermoplastic. Thaum lub sij hawm vuam txheej txheem, ultrasonic kev co yog kis los ntawm lub caij mus rau lub interface ntawm cov hlau ntxig thiab cov yas, thiab lub tshav kub generated los ntawm cov hlau ntxig tiv thaiv cov yas vibration ua rau cov yas yaj tam sim ntawd, yog li tsav lub insert rau hauv qhov chaw, thiab cov yas yaj yaj ntws mus rau hauv qhov ntxig pom cov hniav Zoo li protrusions thiab undercuts, cov inserts yog kho thaum cov yas kho, thiab ob peb inserts yuav muab tso rau tib lub sij hawm.
3. Riveting Ultrasonic riveting yog ib qho kev sib dhos uas ib sab yas yog yaj thiab tom qab ntawd ua kom zoo li kho lwm yam, uas feem ntau yog ua los ntawm cov khoom sib txawv. Kev tsim cov piling thiab kab noj hniav yog txiav txim siab los ntawm cov kev xav tau ntawm daim ntawv thov thiab lub cev qhov ntev ntawm cov piling. Tab sis lub hauv paus ntawm txhua tus qauv tsim yog tib yam. Ntawd yog, thawj qhov chaw sib cuag ntawm lub taub hau vuam thiab cov pawg yuav tsum tau khaws cia kom tsawg kawg nkaus kom lub zog muaj zog tuaj yeem yaj sai. Ultrasonic riveting feem ntau yuav tsum muaj siab amplitude thiab tsis tshua muaj siab. Qee cov ntaub ntawv uas muaj qhov kub thiab txias yog qhov yooj yim los tsim cov taub hau tsis yooj yim. Nyob rau hauv cov ntaub ntawv no, tus qauv kem kawg, siab siab, siab amplitude thiab siab trigger siab yuav siv tau kom tau zoo dua. . Thaum welding, lub taub hau vuam yuav tsum tau qis rau hauv pawg ntawm qhov qis qis qis kom tso cai rau lub sijhawm rau cov khoom tawg thiab tiv thaiv pawg los ntawm deforming vim lub siab.
4. Swaging siv lub zog ultrasonic los yaj cov yas los ua ib feem los kho lwm qhov hauv lub rooj sib txoos. Txoj kev ua no hu ua swaging. Txoj kev deformation ntawm swaging tso cai rau cov yas yuav tsum tau forged mus rau hauv ntau yam duab, thiab txoj kev siv tshuab tsis txwv rau cov kab hla hla. Feem ntau, cov ntaub ntawv uas yooj yim rau swage los yog tsim muaj xws li polypropylene, polyethylene, polymethylpentene, propylene glycol, styrene copolymers, polystyrene, thiab cellulose. Cov ntaub ntawv nyuaj tsis yooj yim li pwm. forging.
