Txhua yam ntawm cov yas vuam txheej txheem thov

Cov khoom yas tiav tuaj yeem tsim los ntawm ntau yam khoom lossis cov khoom, uas tuaj yeem ua ke nrog cov khoom siv kho tshuab, cov nplaum thiab cov txheej txheem vuam. Ntawm peb hom kev sib txuas, cov txheej txheem vuam muaj qhov zoo tshaj plaws, thiab cov ntaub ntawv vuam muaj ntau haiv neeg, thiab cov txheej txheem vuam sib txawv tuaj yeem siv raws li cov khoom sib txawv, qhov ntau thiab tsawg thiab kev siv.

Mechanical fixtures, adhesives thiab vuam txheej txheem tuaj yeem koom nrog ob qho tib si engineering plastics. Cov cuab yeej siv hluav taws xob tuaj yeem txuas tau sai sai ntawm ob lub ntsiab lus, tab sis cov pob qij txha tsis zoo rau cov ntaub ntawv pov thawj thiab cov kev ntxhov siab hauv zos tuaj yeem cuam tshuam cov ntaub ntawv polymer.

Adhesives muab cov khoom zoo los tsim cov pob qij txha zoo heev, txawm li cas los xij, adhesives nyuaj los daws thiab kho qeeb. Nyob rau tib lub sijhawm, thaum siv cov nplaum nplaum, kev sib koom ua ke thiab kev ua kom huv ntawm qhov chaw siab dua.

Vuam tsim cov pob qij txha ruaj khov nrog cov khoom siv kho tshuab ze rau cov khoom ntawm niam txiv. Yas vuam yog txwv rau cov thermoplastic polymers vim hais tias cov ntaub ntawv thermoplastic tuaj yeem muag los ntawm cua sov. Thermosetting polymers tsis tuaj yeem softened los ntawm tshav kub tom qab hardening. Piv nrog rau cov hlau, cov thermoplastic polymers xav tau cua sov tsawg dua rau vuam.

Ultrasonic vuam

Ultrasonic vuam yog tsim los ntawm cov neeg kho tshuab siab zaus kev co. Qhov yuav tsum tau sib sau ua ke yog nias thiab clamped ntawm lub oscillating vuam lub taub hau thiab lub vuam lub taub hau ruaj khov, thiab tom qab ntawd ntawm lub kaum sab xis mus rau qhov chaw sib cuag, tau txais ultrasonic kev co nrog zaus ntawm 20 ~ 40KHz. Hloov cov kev ntxhov siab ntau zaus ua kom muaj cua sov ntawm qhov sib koom ua ke, ua rau cov vuam zoo heev. Cov cuab yeej siv rau cov txheej txheem no yog kim thiab yog li tsim nyog rau cov khoom ntim loj.

Txoj kev vuam no tsuas yog tsim nyog rau vuam qhov me me tsis ntau tshaj li ob peb centimeters ntev. Cov ntawv thov muaj xws li li qub thiab kev tshuaj ntsuam xyuas cov khoom siv kho mob ntawm cov tshuab siv ntau lub taub hau, lub thawv, cov khoom siv tsheb, lub tshuab nqus tsev vacuum, thiab lwm yam.

Kev sib txhuam vuam

Kev sib txhuam vuam ntawm cov thermoplastics (tseem hu ua "rotary welding") ua haujlwm tib yam li cov hlau vuam. Nyob rau hauv cov txheej txheem vuam no, ib daim ntawm substrate yog tsau thiab lwm yam rotates ntawm ib tug tswj angular ceev. Thaum cov khoom raug nias ua ke, kev sib txhuam kub ua rau cov polymer yaj, uas, thaum txias, ua ib qho kev sib txuas. Lub ntsiab welding tsis muaj xws li: kev sib hloov ceev, kev sib txhuam siab, forging siab, vuam lub sij hawm thiab melting ntev.

Kev sib txhuam vuam tuaj yeem tsim cov vuam zoo, cov txheej txheem vuam yooj yim thiab muaj zog rov ua dua. Txawm li cas los xij, vim nws cov txheej txheem yooj yim, nws tsuas yog tsim nyog rau cov ntawv thov uas tsawg kawg ib feem yog puag ncig thiab angular alignment tsis tas yuav tsum tau ua.

Kev vibration vuam

Vibration welding tseem hu ua linear friction welding. Ob qhov thermoplastic rub tawm ib leeg ntawm txoj cai siab, zaus, thiab amplitude kom txog thaum muaj cua sov txaus los yaj cov polymer. Tom qab qhov kev vibration nres, cov khoom sib txuas nrog ib leeg, thiab cov polymer melted solidifies los ua ib qho weld. Vibration welding zoo ib yam li cov vuam vuam, qhov sib txawv yog tias cov lus tsa suab yog linear motion es tsis txhob siv cov lus teb. Txoj kev vuam no yog ceev heev, qhov kev vibration zaus feem ntau yog 100 ~ 240Hz, lub amplitude yog 1 hli ~ 5 hli.

Lub ntsiab kom zoo dua ntawm no welding txheej txheem yog hais tias nws muaj peev xwm weld loj complex linear qhov chaw ntawm kev kub ceev. Lwm qhov zoo muaj xws li: kev sib txuas ntawm ntau qhov chaw, cov cuab yeej vuam yooj yim, vuam yuav luag tag nrho cov khoom siv thermoplastic suav nrog kev txhaj tshuaj molding qhov chaw, extruded qhov chaw, tshuab moulding qhov chaw, thermoforming qhov chaw, foaming qhov chaw thiab stamping qhov chaw, feem ntau yog siv hauv kev lag luam tsheb thiab khoom siv hauv tsev. .

Kev vibration vuam yog tshwj xeeb tshaj yog haum rau cov ntaub ntawv thermoplastic, nrog rau amorphous resins xws li ABS / PC, PVC, PMMA thiab PES; Semi-crystalline resin xws li HDPE, PA, PP, TPO. Dukane's welder pob qij txha hauv tsheb, xws li cov khoom noj khoom haus, dashboards, taillights thiab bumpers; Kev siv dav hlau xws li HVAC cov kav dej, teeb pom kev sab hauv thiab cov chaw cia khoom; Cov cuab yeej siv hauv tsev yog lub tshuab ntxuav tais diav thiab cov tshuaj tua dej, cov tshuaj ntxuav tais diav thiab lub tshuab nqus tsev vacuum.
