2.3. Anti-vibration: riveted pob qij txha tsis yooj yim loosened los ntawm kev co thiab yog haum rau cov kev siv uas tsom rau kev ruaj ntseg.
2.4. Tsis muaj thermal deformation: Tsis zoo li vuam, riveting tsis koom nrog molten hlau, yog li tsis muaj kev pheej hmoo ntawm thermal deformation.
Disadvantages ntawm riveting:
2.1. Ntxiv qhov hnyav: Lub xub ntiag ntawm rivets nce qhov hnyav ntawm lub rooj sib txoos, uas tuaj yeem ua teeb meem hauv qhov hnyav-sensitive daim ntaub ntawv.
2.2. Kev ua haujlwm hnyav: Riveting tuaj yeem siv zog ntau dua li lwm txoj kev sib dhos, tshwj xeeb tshaj yog rau kev tsim khoom loj.
2.3. Aesthetics: Lub xub ntiag ntawm pom rivet hau tej zaum yuav tsis zoo tagnrho los ntawm ib tug zoo nkauj foundations, tshwj xeeb tshaj yog nyob rau hauv daim ntawv thov uas yuav tsum tau ib tug du nto.
2.4. Muaj peev xwm ntawm Corrosion: Yog tias tsis kaw kom zoo, cov pob qij txha riveted tej zaum yuav raug corrosion, tshwj xeeb tshaj yog nyob sab nraum zoov lossis hauv qhov chaw hnyav.
Zuag qhia tag nrho,riveting yog ib txoj kev txhim khu kev qha thiab siv tau zoo ntawm kev koom nrog cov ntawv hlau, tshwj xeeb tshaj yog thaum lub zog thiab kev ruaj ntseg yog qhov tseem ceeb. Txawm li cas los xij, ua ntej xaiv riveting raws li txoj kev sib dhos, nws yog ib qho tseem ceeb uas yuav tsum tau ntsuas nws qhov zoo thiab qhov tsis zoo ntawm cov kev cai tshwj xeeb ntawm daim ntawv thov.
3.Adhesive sib txuas
Cov nplaum tshwj xeeb yog siv los txuas cov ntawv hlau ua ke. Txoj kev no muab kev sib koom ua ke huv thiab zoo nkauj, tab sis tej zaum yuav tsis muaj zog li lwm txoj hauv kev thiab tej zaum yuav nkag siab rau ib puag ncig.
Sheet hlau nplaum nplaum yog lwm txoj kev sib dhos uas siv los koom nrog cov ntawv hlau. Nov yog qhov zoo thiab qhov tsis zoo ntawm daim ntawv hlau sib txuas:
Qhov zoo ntawm cov nplaum nplaum:
3.1. Txo qhov hnyav: Adhesive bonding feem ntau sib dua dua li cov txheej txheem fastening, ua rau nws haum rau kev siv hnyav-rhiab.
3.2. Kev faib tawm kev ntxhov siab: Piv nrog cov khoom siv fastening, cov nplaum nplaum tuaj yeem faib kev ntxhov siab ntau dua nyob rau hauv kev sib koom tes, yog li txo qhov kev pheej hmoo ntawm kev ntxhov siab.
3.3. Sealing: Adhesive bonding muab kev sib khi ua ke uas tiv thaiv kev ya raws, plua plav, thiab lwm yam ib puag ncig.
3.4. Aesthetics: Adhesive bonding txhim kho cov tsos ntawm lub rooj sib txoos los ntawm kev tsim cov pob qij txha du, huv si yam tsis pom cov fasteners.
Disadvantages ntawm adhesive bonding:
3.1. Lub zog: Txawm hais tias cov nplaum niaj hnub tuaj yeem muab cov ntawv cog lus ruaj khov, lawv yuav tsis zoo ib yam li lub zog ntawm vuam lossis cov cuab yeej kho kom haum, tshwj xeeb tshaj yog hauv cov ntawv thov kev ntxhov siab.
3.2. Kev npaj deg: Adhesive bonding yuav tsum tau ua tib zoo npaj qhov chaw kom ntseeg tau tias muaj kev sib raug zoo, uas tuaj yeem ntxiv sijhawm thiab nyuaj rau cov txheej txheem sib dhos.
3.3. Environmental rhiab heev: Adhesives tuaj yeem nkag siab rau ib puag ncig yam xws li kub, av noo, thiab tshuaj lom neeg raug, uas tuaj yeem cuam tshuam rau lawv txoj haujlwm.
3.4. Kev Kho: Kho lossis disassembly ntawm cov nplaum sib koom ua ke yog qhov nyuaj dua li cov txheej txheem fastening.
Thaum xav txog kev sib txuas ntawm cov ntawv hlau, nws yog ib qho tseem ceeb uas yuav tau xaiv cov nplaum tsim nyog rau cov khoom tshwj xeeb thiab kev ua haujlwm. Cov yam ntxwv xws li kev tsim seam, kev npaj saum npoo thiab txheej txheem kho yuav tsum tau ua tib zoo txiav txim siab kom ntseeg tau tias txoj kev sib txuas ua tiav.
4.Clinching
Txoj kev no suav nrog deforming cov ntawv hlau los tsim kom muaj kev sib cuam tshuam ntawm cov khoom. Qhov no yog ib txoj hauv kev sai thiab raug nqi, tab sis yuav tsis muab kev sib koom ua ke zoo li vuam lossis riveting.
Clinching yog txheej txheem txheej txheem txias siv los koom nrog cov ntawv hlau yam tsis tas yuav tsum tau txuas ntxiv los yog cua sov. Nov yog qhov zoo thiab qhov tsis zoo ntawm cov ntawv hlau riveting:
Qhov zoo ntawm cov ntawv hlau clinching:
4.1. Tsis xav tau cov fasteners ntxiv: Clinching tshem tawm qhov xav tau ntawm cov khoom sib cais xws li rivets, screws lossis adhesives, txo cov nqi khoom thiab ua kom yooj yim rau kev sib dhos.
4.2. Lub zog sib koom ua ke: Crimp pob qij txha muab cov tensile zoo thiab shear zog, ua rau lawv haum rau ntau yam kev siv.
4.3. Kev puas tsuaj tsawg kawg rau cov ntawv hlau: Clinching tsis tas yuav tsum tau drilling lossis xuas nrig ntaus hauv cov ntawv hlau, yog li txo qhov kev pheej hmoo ntawm cov khoom puas thiab kev ntxhov siab.
4.4. Versatility: Clinching tuaj yeem siv rau ntau yam ntawm cov ntaub ntawv hlau thiab thicknesses, muab kev tsim thiab tsim tau yooj yim.
Disadvantages ntawm sheet hlau riveting Clinching: Cov cuab yeej tshwj xeeb Clinching yog yuav tsum tau, uas tej zaum yuav xav tau kev nqis peev thawj zaug thiab cov nqi kho mob.
4.2. Kev sib koom ua ke: Hauv qee daim ntawv thov, pom cov ntsiab lus rivet yuav tsis pom zoo, tshwj xeeb tshaj yog cov uas xav tau qhov chaw du.
4.3. Kev txwv kev sib koom ua ke: Piv rau lwm txoj hauv kev xws li vuam lossis riveting, clinching tuaj yeem raug txwv hauv kev tsim qee qhov kev sib koom ua ke.
Thaum txiav txim siab ntawm cov ntawv hlau clinching, nws yog ib qho tseem ceeb rau kev ntsuam xyuas cov kev cai tshwj xeeb ntawm daim ntawv thov, nrog rau kev sib koom ua ke lub zog, qhov tsos thiab kev sib tw. Clinching yog ib qho txiaj ntsig zoo ntawm kev koom nrog cov ntawv hlau, tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov uas cov txiaj ntsig ntawm clinching ua raws li qhov project xav tau.
Txhua txoj kev sib dhos muaj nws qhov zoo thiab qhov tsis zoo, thiab kev xaiv ntawm txoj kev yuav nyob ntawm seb yam xws li daim ntawv thov tshwj xeeb, cov khoom siv, cov khoom siv, thiab cov nqi txiav txim siab. Nws yog ib qho tseem ceeb uas yuav tau ua tib zoo xav txog cov xwm txheej no thaum xaiv txoj kev sib dhos rau cov ntawv hlau.
