Cov hniav so tsheb yog cov khoom siv kev nyab xeeb uas feem ntau hloov pauv hauv cov tsheb, txawm li cas los xij cov cuab yeej ua haujlwm raug tom qab lawv feem ntau tsis pom rau cov neeg tsav tsheb. Cov pwm hniav so tsheb—ib lub cuab yeej siv zoo heev uas ua los ntawm cov hlau zoo thiab ua kom ruaj khov—tsim lub hauv paus ntawm kev tsim cov khoom siv wiper, hloov cov yas thiab roj hmab uas yaj mus ua cov duab zoo nkauj uas ua rau lub qhov rais iav ntshiab hauv txhua qhov huab cua.
Txawm yog rau cov hniav uas muaj cov thav duab ib txwm muaj, cov hniav uas tsis muaj thav duab niaj hnub, lossis cov qauv sib xyaw, qhov zoo ntawm cov pwm txiav txim siab ncaj qha rau qhov khoom sib xws, lub neej ntev, thiab kev ua tau zoo. Thaum cov tsheb thoob ntiaj teb nthuav dav thiab cov qauv kev nyab xeeb nruj dua, kev nkag siab txog kev tsim cov pwm hniav wiper tsheb tau dhau los ua qhov tseem ceeb rau OEMs, cov neeg muag khoom tom qab, thiab cov kws tshaj lij kev yuav khoom.
Cov pwm txhaj tshuaj rau cov khoom yas
Feem ntau ntawm cov khoom siv ntawm lub tshuab nqus tsev—suav nrog cov adapters, lub hau kawg, thiab cov tsev txuas—yog tsim los ntawm kev siv cov yas txhaj tshuaj molding. Cov yas txhaj tshuaj pwm rau lub qhov rais iav yog ib lub tshuab ua haujlwm zoo heev uas txhaj cov yas molten rau hauv cov qhov uas tau tsim tshwj xeeb los ua cov duab zoo nkauj uas xav tau rau cov tshuab wiper.
Cov lus qhia tshwj xeeb muaj xws li:
Kev Qhia Txog Tus Qauv
Pwm puag hlau P20 / S50c
Cavity/core hlau 718 / H13 / P20
Khoom siv PA66 / PP + GF30
Qhov pwm kab 1 + 1 rau ntau qhov kab
Kev kam rau siab ntau lawm±0.015 hli
Piv txwv li, ib daim ntawv sau tseg ntawm cov hniav wiper qis txhawb nqa lub cev pwm siv PP + GF30 cov khoom siv nrog 1 + 1 qhov chaw teeb tsa, pwm qhov loj ntawm 1540×1090×1025 hli, thiab ua tiav lub voj voog txhaj tshuaj 65-thib ob ntawm lub tshuab txhaj tshuaj Haitian 1000T.
Cov pwm extrusion rau cov khoom siv roj hmab wiper
Cov khoom siv so roj hmab—qhov ua haujlwm uas kov lub iav pem hauv ntej—feem ntau yog tsim los ntawm kev txuas ntxiv extrusion lossis txhaj tshuaj molding ntawm cov roj hmab tsis tau kho. Elastomers xws li roj hmab ntuj thiab EPDM sib xyaws yog extruded los ntawm cov tuag uas zoo li tus qauv so daim di ncauj, tom qab ntawd vulcanized hauv cov kab kho tas mus li.
Tsim pwm thiab txheej txheem tsim khoom
Theem Tsim Qauv
Kev tsim cov pwm ntawm lub tshuab so iav tsheb yog ib qho txheej txheem kev tsim kho kom ntxaws uas pib nrog cov phiaj xwm meej rau cov khoom siv so iav. Cov kev xav tseem ceeb suav nrog:
●Cov khoom siv–Cov pwm yuav tsum ua raws li cov nqi shrinkage, cov yam ntxwv ntawm kev ntws, thiab kev coj tus cwj pwm thermal ntawm cov yas lossis roj hmab xaiv
●Ib feem geometry–Cov duab sib xyaw ua ke yuav tsum tau tsim cov qhov kom zoo, suav nrog cov qhov hauv qab, cov tav, thiab cov yam ntxwv snap-fit
●Kev teeb tsa channel txias–Kev txias sib xws tiv thaiv qhov deformation thiab shrinkage ntawm ib feem
●Cov tshuab cua–Kev tso pa tawm kom txaus ua kom cov pa tawm tsis txhob tawm, tiv thaiv cov cim hlawv thiab cov khoom tsis tiav.
●Cov txheej txheem rho tawm–Cov ejector pins uas tau teeb tsa zoo ua kom tshem tawm qhov chaw huv si yam tsis muaj kev puas tsuaj rau saum npoo
Theem Tsim Khoom
Kev tsim cov pwm niaj hnub no vam khom rau cov chaw ua haujlwm CNC ceev ceev uas ua haujlwm ntawm qhov ceev spindle txog li 16,000 rpm nrog kev kam rau siab ntawm±0.015 hli. Cov kauj ruam tseem ceeb suav nrog:
1. Kev npaj pwm puag–Feem ntau yog ua los ntawm P20 lossis S50c hlau uas tau ua ntej lawm
2. Cavity thiab core machining–Kev txiav kom meej heev, EDM (kev siv hluav taws xob tso tawm), lossis txiav hlau
3. Kev ua tiav nto–Kev txhuam kom tiav zoo li daim iav rau cov nplaim sealing tseem ceeb; cov nplaim qhov feem ntau xav tau qhov roughness≤Ra 0.05μm rau kev ua tiav qib A hauv tsheb
4. Sib dhos thiab haum–Cov nto sib cais, cov thaiv swb, cov phaj hnav, thiab cov sliders yuav tsum ua tiav ntau dua 90% ntawm tus nqi sib cuag
5. Kev sim pwm (T1 sim)–Kev ntsuam xyuas kev txhaj tshuaj lees paub qhov loj me ntawm qhov chaw, qhov tsos, thiab lub sijhawm voj voog; cov khoom raug tshuaj xyuas siv CMM fixtures los tshuaj xyuas cov nqi deformation thiab kev sib dhos haum
6. Ntim khoom siv nqus tsev–Cov pwm raug kaw hauv lub tshuab nqus tsev thiab kho rau hauv cov ntoo rau kev thauj mus los hauv hiav txwv uas tsis muaj xeb
