Ua rau thiab kev daws teeb meem ntawm qhov tawg ntawm cov khoom yas

Ua rau thiab kev daws teeb meem ntawm qhov tawg ntawm cov khoom yas

1. Residual stress siab dhau lawm

Hais txog cov txheej txheem kev ua haujlwm, nws yog txoj hauv kev yooj yim tshaj plaws los txo cov kev ntxhov siab seem los ntawm kev txo qhov kev txhaj tshuaj, vim tias qhov kev txhaj tshuaj siab yog proportional rau qhov seem kev ntxhov siab.Nyob rau hauv cov nqe lus ntawm kev tsim pwm thiab kev tsim khoom, lub qhov rooj ncaj qha nrog qhov tsawg kawg nkaus poob siab thiab kev txhaj tshuaj siab tuaj yeem siv tau.Lub rooj vag pem hauv ntej tuaj yeem hloov pauv mus rau ntau lub koob taw tes rooj vag lossis sab rooj vag, thiab lub rooj vag txoj kab uas hla tuaj yeem raug txo.Thaum tsim lub rooj vag sab, lub rooj vag convex tuaj yeem siv tau uas tuaj yeem tshem tawm qhov tawg tom qab molding.

2. Residual stress concentration tshwm sim los ntawm sab nraud quab yuam

Ua ntej demoulding cov khoom yas, yog tias qhov chaw hla ntawm qhov demoulding ejection mechanism me dhau los yog tus naj npawb ntawm cov ejector rods tsis txaus, txoj hauj lwm ntawm ejector rods tsis tsim nyog los yog lub installation yog inclined, tshuav nyiaj li cas tsis zoo, demoulding. txoj kab nqes ntawm cov pwm tsis txaus, thiab qhov ejection kuj loj dhau, qhov kev ntxhov siab yuav tshwm sim los ntawm kev quab yuam sab nraud, uas ua rau tawg thiab tawg ntawm qhov chaw ntawm cov yas.Nyob rau hauv cov ntaub ntawv ntawm xws li faults, lub ejection ntaus ntawv yuav tsum tau ua tib zoo xyuas thiab kho.

3. Cov kab nrib pleb tshwm sim los ntawm cov hlau ntxig

Lub thermal expansion coefficient ntawm thermoplastic yog 9-11 npaug loj dua li ntawm cov hlau thiab 6 npaug loj dua li ntawm txhuas.Yog li ntawd, cov hlau ntxig rau hauv cov yas yuav cuam tshuam tag nrho cov shrinkage ntawm cov yas, thiab qhov tshwm sim tensile kev nyuaj siab yog loj.Ib tug loj npaum li cas ntawm cov residual kev nyuaj siab yuav accumulates nyob ib ncig ntawm lub insert thiab ua rau cov kab nrib pleb nyob rau saum npoo ntawm cov yas.Nyob rau hauv txoj kev no, cov hlau ntxig yuav tsum tau preheated, tshwj xeeb tshaj yog thaum cov kab nrib pleb ntawm cov khoom yas tshwm sim thaum pib ntawm lub tshuab, feem ntau ntawm lawv yog tshwm sim los ntawm qhov kub thiab txias ntawm cov inserts.

4. Kev xaiv tsis raug lossis cov khoom tsis huv

Cov ntaub ntawv sib txawv muaj qhov sib txawv rau qhov kev ntxhov siab nyob.Feem ntau, tsis yog crystalline resin yog qhov ua rau muaj kev ntxhov siab thiab tawg ntau dua li crystalline resin;Cov resin nrog cov khoom siv rov ua dua tshiab muaj cov impurities ntau dua, cov ntsiab lus tsis muaj zog ntau dua, qis zog ntawm cov khoom siv, thiab ua rau muaj kev ntxhov siab tawg.

5. Cov qauv tsim tsis zoo ntawm cov khoom yas

Cov kaum ntse ntse thiab cov ntawv hauv cov qauv yas feem ntau yuav tsim kev ntxhov siab, ua rau tawg thiab tawg ntawm qhov chaw ntawm cov yas.Yog li ntawd, lub kaum sab nrauv thiab sab hauv ntawm cov qauv yas yuav tsum tau ua rau hauv arcs nrog lub vojvoog siab tshaj plaws kom deb li deb tau.

6. Kev tawg ntawm cov pwm

Nyob rau hauv cov txheej txheem ntawm kev txhaj tshuaj molding, vim qhov rov ua haujlwm ntawm kev txhaj tshuaj ntawm cov pwm, kev qaug zog tawg yuav tshwm sim ntawm cov npoo nrog cov kaum sab xis hauv cov kab noj hniav, tshwj xeeb tshaj yog nyob ze ntawm qhov txias txias.Nyob rau hauv cov ntaub ntawv ntawm xws li tawg, tam sim ntawd xyuas seb lub nto ntawm cov kab noj hniav sib haum mus rau lub tawg muaj tib lub tawg.Yog tias qhov tawg yog tshwm sim los ntawm kev xav, cov pwm yuav tsum tau kho los ntawm machining.

Cov khoom siv yas hauv lub neej, xws limov nplej, Sandwich tshuab,ntim khoom noj, yas noj su thawv , cia cov kaus poom ,yas yeeb nkab fittings, thiab lwm yam., tuaj yeem zam cov kab nrib pleb zoo.
