Kev ua haujlwm ntawm kub khiav hauv yas pwm tsim

Kub khiav (HRS) kuj yog hu ua kub nozzle, uas yog, lub solidified nozzle hloov mus rau hauv lub molten nozzle. Nws muaj pes tsawg leeg yog yooj yim, feem ntau suav nrog splitter phaj, kub nozzle, kub maub los, thiab lwm yam. Lub splitter phaj yuav muab faib ua I-shaped, X-shaped, Y-shaped, T-shaped, lub qhov ncauj zoo li tus thiab lwm yam tshwj xeeb daim duab raws li. nws cov duab; Qhov kub nozzle tuaj yeem muab faib ua cov dej loj, lub taub hau ntse thiab rab koob valve nozzle raws li cov duab; Lub tshuab ntsuas kub tuaj yeem muab faib ua hom tseem ceeb saib, hom plug-in thiab lub computer centralized tswj hom raws li qhov ntsuas kub.
Hauv kev txhaj tshuaj molding txheej txheem, cov kub khiav yog siv ua ke nrog cov pwm thiab ua lub luag haujlwm tseem ceeb heev. Piv txwv li, nyob rau hauv kev txhaj tshuaj molding ntau lawm ntawm ultra-nyias qhov chaw (xws li lub xov tooj ntawm tes roj teeb cover), high-precision thiab high-zoo khoom yuav ua tau yooj yim tsim los ntawm kev siv kub khiav; Rau kev txhaj tshuaj molding raw cov ntaub ntawv uas tsis zoo fluidity (xws li LCP), kev siv cov kub khiav tuaj yeem txhim kho fluidity ntawm raw cov ntaub ntawv thiab xyuas kom meej qhov zoo ntawm kev txhaj tshuaj molding; Rau qee qhov loj txhaj tshuaj molding qhov chaw, xws li lub tsheb bumpers thiab lub qhov rooj vaj huam sib luag, TV rear vaj tse, cua txias vaj tse, thiab lwm yam., kev siv cov kub khiav ua rau qhov nyuaj heev txhaj molding kuj yooj yim.
Nyob rau hauv kev txhaj tshuaj molding ntawm ntau kab noj hniav pwm, nws yog tsis yooj yim sua rau tsim yam tsis muaj kub khiav. Nws tuaj yeem hais tias kub khiav yog lub tshuab zoo tshaj plaws los xyuas kom meej qhov sib npaug ntawm tus khiav. Vim yog lub zog shear ntawm cov yas hauv cov neeg khiav dej num, txawm li cas los xij, qhov sib npaug geometric ntawm cov pwm yog qhov tsim nyog, qhov hnyav ntawm cov khoom molded yog qhov nyuaj rau kev ua kom zoo ib yam. Tshwj xeeb tshaj yog rau cov pwm nrog ntau cov kab noj hniav, yog tias tsis siv cov kub khiav, sab nraud ntawm cov khoom pwm yuav sib zog dua li sab hauv.
Rau cov txheej txheem yas, nws yog qhov pheej yig heev los siv kub khiav ntev npaum li muaj qee qhov kev txhaj tshuaj ntau lawm. Qhov no yog vim qhov kub khiav pab cov lag luam tshem tawm cov nozzle hauv kev txhaj tshuaj molding ntau lawm. Feem ntau, cov dej nkag tsis tuaj yeem rov qab siv dua. Qee zaum, qhov hnyav ntawm lub nozzle yuav luag tib yam li ntawm cov khoom. Yog tias siv cov tshuaj nozzle txhaj tshuaj molding, nws txhais tau hais tias cov ntaub ntawv pov tseg yog ntau npaum li cov khoom. Raws li qhov kev suav no, 30 feem pua ​​​​ ~ 50 feem pua ​​​​ntawm cov khoom siv raw tuaj yeem txuag tau tom qab siv cov kub khiav. Tsis tas li ntawd, tus khiav kub kuj tseem tuaj yeem txo qhov hnav ntawm pwm thiab ua kom lub neej ntawm pwm. Feem ntau, kev pab cuam lub neej ntawm kub khiav tuag yog ob zaug uas zoo nozzle tuag.
Txawm hais tias muaj pes tsawg leeg ntawm cov kub khiav yog qhov yooj yim, txhua yam ua haujlwm tseem ceeb heev. Feem ntau, cov neeg ua haujlwm kub kub zoo muaj qhov yuav tsum tau ua rau cov qauv tsim thiab cov khoom siv. Raws li rau Xianrui kub khiav, tag nrho cov cua sov thiab ntsuas kub ntawm cov xov hlau raug xaiv los ntawm Kaus Lim Qab Teb, thiab tag nrho cov hlau siv los ntawm Nyiv. Cov no yog qhov yuav tsum tau ua ua ntej kom ntseeg tau tias qhov zoo ntawm qhov kub khiav.
Tsis tas li ntawd, tus neeg muag khoom kub kub kuj xav tau los pab cov neeg siv khoom tsim thiab teeb tsa qhov kub khiav zoo raws li tus neeg siv khoom cov khoom yas thiab cov pwm siv. Xianrui muaj cov kws tshaj lij kub khiav los ntawm Kaus Lim Qab Teb, uas tuaj yeem tsim cov kev daws teeb meem tsim nyog raws li cov neeg siv khoom cov khoom lag luam kom ntseeg tau tias qhov ua tau zoo tshaj plaws ntawm kev kub khiav hauv kev txhaj tshuaj molding. Piv txwv li, nyob rau hauv lub tsim ntawm muab cov kub khiav rau txhaj molding ntawm Shanghai General Motors qhov rooj panels, cov khoom tseem ceeb ntawm cov kub khiav yog xaiv raws li tag nrho xav txog cov ntaub ntawv siv rau lub qhov rooj panels.
Yog hais tias lub qhov rooj vaj huam sib luag yog ua los ntawm PP cov khoom, nws yog feem ntau txaus siv peb-point kub khiav, uas yog, Y-shaped splitter phaj thiab peb kub nozzles. Cov tswv yim no zoo heev txo cov nqi tsim khoom ntawm qhov chaw ntawm kev ua kom cov molding zoo ntawm cov khoom; Yog hais tias lub qhov rooj vaj huam sib luag yog ua los ntawm cov khoom siv hluav taws xob ABS, nws yuav tsum siv tsib lub ntsiab lus kub khiav, uas yog, ib qho tshwj xeeb splitter phaj thiab tsib lub nozzles kub, los xyuas kom meej qhov zoo molding ntawm cov khoom.
Thaum txhim kho qhov kub khiav, xyuam xim rau cov ntsiab lus hauv qab no:
● Kev tshuaj xyuas tag nrho ntawm cov neeg khiav dej num kub, suav nrog txhua qhov ntev, tsis kam thiab ntau;
● Ua tiav xyuas qhov ntev ntawm qhov cuam tshuam ntawm pwm thiab kub khiav;
● Ua ntej txhim kho lub vaj huam sib luag, tus khiav kub yuav tsum tau ua tib zoo soj ntsuam nrog lub ntsuas kub, thiab tsuas yog tuaj yeem ua haujlwm tom qab lees paub nws qhov kev ua haujlwm ib txwm muaj;
● Ua ntej kev tsim khoom, qhov kub khiav yuav tsum tau kuaj xyuas thaum kawg nrog lub tshuab multimeter, txwv tsis pub nws yuav tsum tsis txhob pib;
● Ua ntej pwm kaw, nws yog ib qho tsim nyog yuav tsum tua hauv huab cua. Thaum tua hauv huab cua, npog B phaj pwm nrog cov duab los qhia, thiab tom qab ntawd kaw cov pwm thiab kuaj cov pwm.
Txhawm rau pab cov neeg siv khoom siv kub khiav kom raug, tus neeg muag khoom kub kub yuav tsum muab kev cob qhia rau cov neeg siv khoom. Cov ntsiab lus ntawm kev cob qhia yuav tsum muaj xws li:
● Lub hauv paus ntsiab lus ntawm kub khiav. Tus khiav kub ua kom cov yas nyob rau hauv cov khiav molten los ntawm hluav taws xob cua sov. Ntawm no, peb yuav tsum tau hais qhia rau cov neeg siv khoom tias thaum cov kub khiav ua haujlwm hauv pwm, nws yuav tsum muaj kev ntsuas zoo thermal rwb thaiv tsev. Vim li no, square hlau tsis tuaj yeem siv los hloov cov kub khiav thaum ua cov kab noj hniav splitter, uas yog qhov tseem ceeb heev hauv kev txhaj tshuaj molding.
● Kawm kom raug rau nruab thiab disassemble lub kub khiav. Ua ntej tshaj plaws, peb yuav tsum qhia rau cov neeg siv khoom paub txog kev sib khi txoj haujlwm ntawm tus neeg khiav dej num kub, uas suav nrog kev sib khi ntawm lub taub hau kub thiab lub phaj splitter, lub sealing ntawm lub taub hau kub thiab pwm A phaj, sealing ntawm lub ntsiab nozzle thiab cov vaj huam sib luag, lub sealing ntawm lub valve koob thiab lub valve koob qhia lub tes tsho, thiab lub sealing ntawm lub ntsiab nozzle thiab kub khiav.
● Kev tu cov neeg khiav dej num kub. Txhawm rau kom cov neeg siv khoom paub tias ib zaug cov neeg khiav dej num kub muaj teeb meem, nws yuav tsum tau muab tshem tawm ntawm cov pwm los kho. Cov txheej txheem no yuav siv sij hawm tsawg kawg yog 8 teev. Rau cov neeg siv khoom, tus nqi poob yog li 10 npaug ntawm cov neeg xa khoom kub khiav. Yog li ntawd, nws yog ib qho tseem ceeb heev kom tswj tau qhov kub khiav los ntawm cov neeg ua haujlwm puv sijhawm lossis ib nrab hnub.
