1.Material tube kub:
Qhov kub ntawm cov resin melted feem ntau yog ua tiav los ntawm cua sov nrog lub hwj chim. Qhov kub nce ntawm cov yas los ntawm cov khoom mus rau lub xeev molten feem ntau yog tshwm sim los ntawm qhov kub thiab txias ntawm cov khoom siv raj thiab cov cua sov shear los ntawm kev sib hloov ntawm cov ntsia hlau. Hauv kev xav, qhov piv ntawm lub zog lawv muab yog 3: 7.
Nyob rau hauv cov nqe lus ntawm cov khoom siv lub raj kub qhov chaw, qhov sib txawv kub yog teem raws li cov ntaub ntawv raw sib txawv, cov uas qhov kub ntawm lub hauv ntej kawg (nozzle cheeb tsam) yog me ntsis qis dua qhov nruab nrab kawg kom tsis txhob muaj qhov ntswg; Sab nraub qaum (qhov chaw pub mis) kuj yuav tsum qis dua qhov nruab nrab, 20-30 degrees qis dua qhov kawg ntawm sab xub ntiag, feem ntau los tiv thaiv kev noj zaub mov tsis zoo. Lwm qhov zoo dua yog qhov tso pa tawm yuav zoo dua, thiab cov khoom lag luam tsis tshua muaj qhov tsis xws luag xws li cov xov hlau nyiaj.
2. Pwm kub:
Teem lub pwm kub pom zoo los ntawm cov khoom siv raw khoom raws li cov khoom sib txawv. Pwm kub tuaj yeem cuam tshuam cov crystallinity ntawm cov resin, uas nyob rau hauv lem cuam tshuam rau stability ntawm cov khoom (crystalline khoom). Lwm qhov txiaj ntsig ntawm pwm kub yog tias nws tuaj yeem pab cov ntaub ntawv nyoos ntws zoo dua hauv cov pwm kab noj hniav.
Cov pwm kub cuam tshuam rau qhov ntws ntawm cov yaj thiab cov txheej txheem txias ntawm cov yaj, yog li cuam tshuam rau glossiness ntawm daim iav khoom, thiab tuaj yeem cuam tshuam zoo rau cov glossiness ntawm cov khoom tom. Tau kawg, nws kuj tseem muaj feem cuam tshuam rau qib ntawm deformation. Hauv luv, muaj ntau yam txiaj ntsig.
3. Roj kub:
Hydraulic txhaj tshuaj molding tshuab feem ntau siv hydraulic roj xa mus rau lub siab, thiab nws qhov kub thiab txias yog cov roj kub (tsis yog cov roj ntawm cov roj sib sib zog nqus kib ua khob noom cookie sticks, hehe....) Cov roj kub tsim nyog tuaj yeem ua rau lub neej ntawm lub tshuab thiab txhim kho. ruaj khov.
Thawj yog vim li cas cov roj foob yuav muaj hnub nyoog;
Qhov thib ob yog vim li cas yog qhov nthuav dav coefficient ntawm cov roj foob yog qhov sib txawv ntawm cov roj kheej kheej, uas tseem yog qhov laj thawj tseem ceeb vim li cas cov tshuab hydraulic xau roj.
Yog li tam sim no kuj tseem muaj ob peb lub tshuab txhaj tshuaj molding tshuab uas siv lub ntiaj teb tsis tshua muaj hlau roj foob. Lub nplhaib sib khi ntawm kev txhaj tshuaj molding tshuab roj thooj voos kheej kheej feem ntau yog U-shaped rings ua los ntawm cov khoom siv PU. Vim yog cov yam ntxwv ntawm PU yas, nws qhov kub thiab txias yog nyob ib ncig ntawm -30 txog 80 degrees.
Yog tias cov roj kub siab tshaj 55 degrees, vim qhov kub ntawm cov roj lub tog raj kheej thaum lub sijhawm ua haujlwm, qhov kub ntawm lub nplhaib sealing nws tus kheej yuav siab tshaj 55 degrees thaum nws nyob ruaj ruaj, thiab kev sib txhuam kub yuav raug tsim thaum nws nyob hauv kev txav. Qhov kub ntawm nws qhov chaw sib cuag nrog lub workpiece yuav siab tshaj 100 degrees thaum nws nyob hauv kev txav. Lub sijhawm ua haujlwm ntev yuav ua rau lub neej luv luv ntawm lub nplhaib sealing, thiab cov khoom siv ntawm qhov chaw ua haujlwm ntawm lub nplhaib sealing yuav ua rau kev laus thiab deformation.
Yog li ntawd, nws yog qhov zoo tshaj plaws los tswj qhov kev txhaj tshuaj molding roj kub ntawm qis qis kom tsis txhob muaj kev puas tsuaj rau lub nplhaib sealing. Txawm hais tias qhov zoo tshaj plaws ua haujlwm kub rau hydraulic roj yog nyob ib ncig ntawm 45 degrees, tswj cov roj kub ntawm ib ncig ntawm 35 degrees tsis cuam tshuam rau kev ua haujlwm ntawm hydraulic system. Tab sis nws tsis tuaj yeem qis dhau, vim nws yuav cuam tshuam rau kev ua haujlwm ntawm hydraulic system.
