1, Tej teeb meem thiab kev daws teeb meem hauv extrusion molding
1.1 Yas hlawv
Yas hlawv yog ib qho kev tsis zoo nyob rau hauv cov txheej txheem yas extrusion, feem ntau manifested li: kub siab heev zaub; Muaj ntau cov pa luam yeeb thiab muaj zog tsw ntxhiab tsw ntawm lub qhov ncauj tuag ntawm lub taub hau ntawm lub tshuab, thiab thaum mob hnyav, tej zaum yuav muaj suab nrov nrov; Muaj cov hluav taws kub nyhiab hauv cov txheej yas extruded; Muaj cov npuas txuas ntxiv ntawm cov nplaum nplaum;
Kev daws: Thaum lub sij hawm extrusion txheej txheem, nws yog ib qho tsim nyog yuav tsum tau ntxiv dag zog rau kev soj ntsuam xyuas seb lub tshuab cua sov thiab cua txias puas ua haujlwm zoo; Qhov chaw ntawm extrusion kub yuav tsum tau txiav txim raws li cov txheej txheem yuav tsum tau thiab ceev ntawm lub hau ntswj; Tsim nyog tswj lub sij hawm cua sov thiab tu lub extrusion system tsis tu ncua.
1.2 Plasticization tsis zoo ntawm cov khoom extruded
Lub ntsiab manifestations ntawm tsis zoo plasticization yog: lub extruded txheej muaj toad daim tawv nqaij zoo li kev ntxhib los mos; Qhov saum npoo ntawm cov yas yog blackened, npub, thiab muaj cov kab nrib pleb me me; Cov txheej txheem extruded muaj pom tseeb seams ntawm cov nplaum sib koom.
Kev daws: Ua tib zoo mloog rau qhov kev xav ntawm extrusion kub tswj; Qhov zoo thiab cov khoom npe ntawm cov khoom siv yuav tsum tau lees paub; Peb tsis tuaj yeem ua qhov muag tsis pom qhov tso zis thiab nce extrusion ceev; Ntxiv dag zog rau kev khaws cia cov ntaub ntawv raw, tshwj xeeb tshaj yog nyob rau hauv cov txheej txheem yas ziab; Tsim nyog faib cov pwm los txhim kho extrusion siab thiab ntsia hlau reflux.
1.3 Muaj qhov pores lossis npuas hauv ntu ntu ntawm txheej extruded
Kev daws: Qhov kub ntawm txhua ntu ntawm cov ntsia hlau yuav tsum tswj kom tsim nyog; Pre qhuav cov ntaub ntawv siv ua ntej; Cov txheej txheem kev ua haujlwm nruj me ntsis txhawm rau txhim kho lub peev xwm los ntsuas qib ntawm cov yas yas yas; Ua tib zoo saib xyuas qhov chaw tsim khoom thiab cov khoom siv khaws cia.
1.4 Qhov loj extrusion tsis tsim nyog
Feem ntau manifested li eccentric core, sheath thickness los yog txheej kab uas hla tshaj qhov kam rau ua
Kev daws: Sab nraud ntawm lub plhaub yuav tsum tau ntsuas tsis tu ncua thiab hloov kho raws sijhawm; Tsim nyog xaiv thiab kho cov pwm extrusion; Ua tib zoo mloog cov kev hloov nro ntawm lub cable thiab kho lawv raws sijhawm; Kev tswj qhov kub thiab txias yuav tsum ua raws li qhov yuav tsum tau ua;
1.5 Lub zog sib txuas ntawm cov kab xev ntev ntev tsis tsim nyog
Kev daws: Kev saib xyuas yuav tsum tau them rau cov pwm yuav tsum tau ua, thiab yog tias tsim nyog, kev hloov kho yuav tsum tau ua raws li cov tub ntxhais cable; Tsis txhob cia cov ntaub qhwv kom txias sai sai los txhim kho nws txoj kev sib txuas; Peb yuav tsum tsis txhob qis tshaj qhov kub ntawm lub tshuab taub hau thaum txhim kho lub peev xwm ntawm lub plhaub; Ua tib zoo saib xyuas qhov ntim ntawm cov tshuaj pleev, kom cov txheej nyias nyias tuaj yeem raug tshem tawm los ntawm maj mam kov cov tub ntxhais cable nrog koj cov ntiv tes.
Dkos npe rau kev txiav txim siab
2.1 Phab ntsa thickness uniformity teeb meem
Hauv tib cov khoom, yog tias muaj qhov sib txawv ntawm qhov tuab ntawm qhov sib txawv, nws tuaj yeem ua rau tsis sib xws, ua rau tsis sib xws ntawm cov kev ntxhov siab sab hauv thiab deformation loj ntawm cov khoom.
2.2 Qhov teeb meem ntawm kev hloov pauv ntawm arc ntawm cov kaum ntse ntse.
Cov duab zoo li zoo ib yam li lub kaum sab xis steel, channel steel, thiab "I-shaped" steel hauv cov hlau. Yuav tsum muaj qee lub vojvoog ntawm kev hloov pauv ntawm lub kaum sab xis ntawm qhov profile, txwv tsis pub nws yuav ua rau muaj kev ntxhov siab thiab cov khoom feem ntau tawg thaum siv.
2.3 Qhov teeb meem ntawm thickness ntawm cov ntaub ntawv profiled.
Lub thickness ntawm cov khoom yas yog txwv, txwv tsis pub, kev ntxhov siab sab hauv thaum lub sij hawm molding txheej txheem tuaj yeem ua rau cov khoom tawg. Vim lub thickness loj ntawm qhov profile, txawm tias nws tuaj yeem ua tau zoo yog tseem muaj teeb meem; Txawm tias tom qab molding, qhov kev ntxhov siab sab hauv ntawm cov khoom yog qhov teeb meem ntawm kev txhawj xeeb rau txhua tus. Raws li tus neeg siv kev tso cai, cov khoom no tuaj yeem hloov kho rau hauv cov duab tsim nyog. Nyob rau hauv txoj kev no, nws tuaj yeem ua kom zoo molding thiab tseem tiv thaiv kev ntxhov siab ntau dhau hauv cov khoom.
