Txhaj pwm rau sab laug thiab sab xis armrest inserts
Sab laug thiab sab xis armrests yog qhov tseem ceeb ntawm lub rooj zaum kho mob. Daim duab kos duab yog qhia hauv daim duab 1. Qhov loj tshaj plaws ntawm cov khoom yog 201.34 mm x 81.78 mm x 60.61 mm, qhov nruab nrab thickness ntawm cov yas yog 12.00 hli, cov khoom ntawm cov yas yog PA6. ntxiv rau 50 feem pua GF, tus nqi shrinkage yog 1.004, thiab qhov zoo ntawm cov yas yog 124.20 gram. Cov txheej txheem kev cai rau cov khoom yas yog tias yuav tsum tsis muaj qhov tsis xws luag xws li peaks, tsis txaus siab rau kev txhaj tshuaj molding, cov kab ntws, qhov pores, warpage deformation, nyiaj streaks, cov khoom txias, dav hlau kab, thiab lwm yam.
Nws tuaj yeem pom los ntawm daim duab 1 tias cov qauv ntawm cov yas yog L-zoo li tus, ib kawg ntawm lub tog raj kheej muaj lub puab qhov, uas yuav tsum tau muab tso rau hauv lub hardware, thiab nws ncig muaj ib tug uniform hniav zoo, uas muaj peev xwm ua si. lub luag haujlwm ruaj khov tom qab tau muab tso rau hauv cov yas.
Lub hom phiaj ntawm kev ntxig rau hauv cov khoom yas yog txhawm rau ua kom lub zog hauv zos, hardness, hnav tsis kam, conductivity lossis sib nqus permeability ntawm cov khoom yas; los yog ua kom muaj kev ruaj ntseg ntawm cov duab thiab qhov loj ntawm cov khoom yas, txo qhov deformation, thiab txhim kho qhov tseeb; Los yog txo cov yas
Lub trumpet thiab ua tau raws li ntau yam kev cai. Cov ntaub ntawv ntawm cov khoom ntxig muaj xws li ntau yam tsis-ferrous lossis ferrous hlau, nrog rau iav, ntoo, thiab molded yas qhov chaw, ntawm cov hlau inserts feem ntau yog siv.
Kev siv cov inserts feem ntau ua rau tus nqi ntawm cov khoom yas thiab ua rau cov qauv pwm nyuaj. Tsis tas li ntawd, kev teeb tsa ntawm cov ntxig rau hauv pwm thaum lub sij hawm molding ntawm cov khoom yas yuav txo tau cov khoom ntawm cov yas, thiab nws yog ib qho nyuaj rau kev paub automation. Siv cov khoom yas uas twb tau tsim los ua pwm rau ntxig,
Peb feem ntau hu nws ua pwm ntxig. Cov pwm overmolding tuaj yeem ua tiav cov nyhuv tib yam li ob-xim pwm, thiab nws kuj yog ib qho kev xaiv zoo thaum lub tshuab molding ob-xim tsis muaj.
Tom qab cov hlau ntxig ntxig rau hauv cov yas, yuav muaj ntau yam teeb meem, kev ceev faj ntau yog raws li hauv qab no;
1) Tom qab cov hlau ntxig ntxig rau hauv cov yas, txhawm rau kom ntseeg tau tias nws ruaj khov thiab txhim khu kev qha, tsis xoob, thiab tsis plam tawm, nws yog ib qho tsim nyog yuav tsum ua cov kauj ruam, undercuts, qauv lossis knurling nyob rau hauv ib feem ntawm embedded. cov hlau ntxig los tiv thaiv nws los ntawm kev poob.
2) Cov duab thiab qhov loj ntawm cov hlau ntxig yuav tsum tau them sai sai rau cov khoom siv tes ua haujlwm, cov khoom siv tau yooj yim rau kev ua, tuaj yeem tso siab rau lub sijhawm txhaj tshuaj molding, thiab tuaj yeem yooj yim tshem tawm thiab demolded tom qab txhaj tshuaj.
3) Vim muaj cov khoom sib txawv ntawm ob cov ntaub ntawv, tshwj xeeb tshaj yog cov coefficients sib txawv ntawm thermal expansion, cov hlau ntxig yuav ua rau cov khoom yas nyob ib ncig ntawm lub ntxig rau tawg. Yog tias cov txiv ntoo tooj liab tau muab tso rau hauv cov khoom siv PC thaum txhaj tshuaj molding, nws yuav ua rau tawg. Yuav tsum tau Lub preheating ntawm lub insert yuav tsis txhob cracking.
4) Nws tsis tsim nyog los tsim cov pwm ntau kab noj hniav nrog cov pwm rau kev tso qhov ntxig, vim nws yuav siv sij hawm los tso qhov ntxig thiab ncua sij hawm txhaj tshuaj. Yog li ntawd, yuav tsum muaj kev ntsuam xyuas dav dav thaum lub sij hawm tsim pwm.
Cov khoom ntawm cov yas yog PA6 ntxiv rau 50 feem pua GF, thiab tus nqi shrinkage yog 1.004. Nylon thiab iav fiber ntau tuaj yeem ua lub luag haujlwm txhawb nqa. Tom qab cov iav fiber ntau ntxiv rau cov yas, qhov shrinkage tus nqi txo qis, thiab qhov poob qis zuj zus tuaj nrog qhov nce ntawm cov iav fiber ntau. Hauv kev tsim qauv Thaum siv cov pwm uas muaj feem ntau ntawm cov iav fiber ntau yas, nws yuav tsum tau them sai sai rau qhov me me shrinkage tus nqi ntawm cov khoom loj los yog complex, thaum lub shrinkage tus nqi yog anisotropic.
Cov yas yog symmetrical, pwm tsim kab noj hniav nyob qib 1 ntxiv rau 1, thiab pwm puag yog CI3540 qauv pwm puag. Lub rooj vag yog tsim los rau submersible thimble los pub kua nplaum. Sab ntawm lub luj tshib ntawm cov yas nrog cov ntxig yog tsim rau hauv pem teb sab ntawm pwm, thiab cov tub ntxhais slider yuav tsum tau tsim. Lub ntuj sab ntawm pwm embryo
Cov pwm ruaj khov thiab txav tau pwm blanks kuj muaj qhov chaw pins kom rigidity.
Txhawm rau kom yooj yim kho cov khoom siv, lub slider yog tsav los ntawm lub tog raj kheej roj. Hauv qab ntawm lub slider yog tsim los nrog ib tug hnav-resistant phaj 17, ua los ntawm 9CrWMn, tshav kub-kho HRC 60-62, thiab ib tug roj zawj yog qhib rau saum npoo. Thaum cov roj lub tog raj kheej yog cov tub ntxhais-rub, nws yog ib qho tsim nyog los tsim lub inclined wedge 19 txhawm rau txhawm rau ntsuas lub tog raj kheej roj. Dynamic qauv
Rau cov tub ntxhais-rub cov pwm, lub tog raj kheej tuaj yeem muab xauv tau yooj yim nrog lub npoo. Nyob rau hauv cov pwm ruaj khov rub tawm los yog qee cov pwm kub khiav, qee zaum nws nyuaj rau xauv lub tog raj kheej roj, thiab nws yog ib qho tsim nyog los tsim cov roj kheej kheej txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau nws nws yog ib qho tsim nyog yuav tsum tau txiav cov pwm ntawm cov pwm. Lub slider yuav tsum tau rov pib dua ua ntej kaw lub pwm, Yooj yim rau muab tso rau hauv qhov ntxig. Daim ntawv qhia yog tsim nyob rau hauv qab ntawm lub tog raj kheej mounting phaj los muab kev taw qhia rau kev txav ntawm lub tog raj kheej piston pas nrig thiab nce rigidity. Thaum tsim pwm ntawm lub tog raj kheej core rub, nws yog ib qho tsim nyog yuav tsum tau them sai sai rau qhov tsim ntawm ib qho kev sib txuas ntawm lub taub hau ntawm lub tog raj kheej piston pas nrig. Ib sab ntawm qhov txuas txuas yog tsim nrog lub qhov ntsia hlau, thiab cov xov ntawm lub tog raj kheej piston pas nrig yog screwed rau hauv lub qhov ntsia hlau. Lwm qhov kawg ntawm qhov txuas txuas yog tsim nrog T-shaped block. Lub T-slot yuav tsum tau tsim los txuas nrog cov kev sib txuas. Tsis txhob ntsia hlau xov ntawm tus pas nrig piston ncaj qha mus rau hauv lub slider, thiaj li tsis ua rau lub slider txav unsmoothly.
