INSERTION PROCESS OF THERMAL BREAK ALUMINIUM PROFILES

Aluminum muaj ntau yam zoo, nws yog cov khoom zoo tshaj plaws rau cov qauv fenestration system hauv ntau txoj kev. Tab sis aluminum kuj yog ib qho khoom uas muaj kev hloov cua kub siab uas yuav hloov pauv qhov kub ntawm sab nraud sai. Yog li ntawd, tib neeg tsim thermal break system kom txo qhov kev hloov cua kub.

Tam sim no, muaj ob hom khoom uas feem ntau siv hauv thermal break system:

• Polyurethane Pour & Debridge
• Polyamide thermal so strips

Rau polyurethane pour & debridge system, ib tug channel yog tsim rau hauv cov txhuas profiles thiab sau los ntawm cov kua polyurethane. Tom qab ntawd tshem cov hlau txuas hauv qab ntawm cov channel kom cia cov polyurethane hardened los ua ib qho insulator. (raws li qhia hauv daim duab 1 thiab daim duab 2)

Rau polyamide thermal so strip system, polyamide sawb yog mechanically ntxig ntawm ob aluminium profiles. Polyamide sawb yog lub insulator. (raws li qhia hauv daim duab 3 thiab daim duab 4)

Hnub no, peb yuav tham txog txoj kev ntxiv uas xav tau hauv cov hlau aluminium thermal break. Vim tias ntxiv rau qhov zoo ntawm cov polyamide strip nws tus kheej, qhov thev naus laus zis ntawm txoj kev ntxiv yog ib qho tseem ceeb kom txiav txim siab qhov zoo ntawm cov hlau aluminium thermal break.

Feem ntau hais lus, cov txheej txheem ntxig yog ua tiav los ntawm plaub kauj ruam:
Profile kev lag luam
Sawb insertion
Crimping
Shear zog test

Thawj kauj ruam: Profile K nulling
Profile knurling yog los ua kom "ntiv" ntawm qhov chaw ntawm cov hlau aluminium uas xav tau ntxiv polyamide strips.(li qhia hauv Duab 5 thiab Duab 6)

Lub hom phiaj ntawm knurling yog kom nce qhov roughness ntawm cov profile, kom nws tuaj yeem txhim kho qhov zog shear ntawm cov hlau aluminium composite. Profile knurling yog ib qho txheej txheem tseem ceeb heev.

• Kauj ruam ob:  S taug kev Kuv lus hais

Qhov polyamide strip raug muab tso rau hauv cov aluminum notches sab saum toj thiab sab qab hau los ntawm txoj kev qhia ntawm strip insertion machine, kom lawv tuaj yeem txuas nrog. (xws li qhia hauv Duab 7) Qhov txheej txheem ntxiv ntawm qee cov khoom siv tau koom nrog hauv knurling machine, uas yog, qhov polyamide strip raug muab tso rau hauv aluminum profiles hauv txheej txheem profile knurling. Tom qab muab tso, qhov polyamide strip thiab aluminum profiles tsis yog tightly bonded. Lawv yog loose. Strips thiab aluminum profiles tuaj yeem txav nrog ib leeg.

Rau cov aluminum profiles uas ob lub notches center qhov deb tsawg dua 10mm (xws li qhia hauv Duab 8), nws nyuaj rau muab tso polyamide strips los ntawm strip inserting machine. Hauv qhov xwm txheej no, peb tsuas tuaj yeem muab tso polyamide strips los ntawm tes.

• Kauj ruam peb: C rimping

Crimping yog qhov nyuaj ntawm aluminum profiles thiab thermal break strips siv peb set ntawm hard rolling wheels. Peb set ntawm rolling wheels yog siv rau preloading, compressing, thiab correcting raws li. (xws li qhia hauv Duab 9 thiab 10)

• Kauj ruam plaub: S hnov S zog T yog

Qhov kev sim yog yooj yim heev. Thov siv zog nce ntxiv rau hauv profile longitudinally txog thaum muaj kev tsis sib haum ntawm aluminium profile thiab thermal break strip.(zoo li qhia hauv Figure 11 thiab Figure 12)

Tsis tas li ntawd, qhov kev sim no tsis yog kev sim ib zaug. Peb yuav tsum sim 10 cov qauv ntawm 100mm. Thaum lub sij hawm tus txheej txheem, nws yuav tsum tau muab sau tseg hais tias lub Upper thiab qis clamping blocks tsis tau pinched rau thermal so strips. Lub hom phiaj los ntsuas lub zog shear yog sim lub zog ntawm kev sib xyaw ntawm thermal so strips thiab aluminium profiles. Suav teb tus txheej txheem teev tseg tias tus yam ntxwv tus nqi ntawm longitudinal shear zog ntawm thermal so aluminium profile yuav tsum ntau dua 24N / hli.
