Taw qhia rau ABS Sheet
ABS (Acrylonitrile Butadiene Styrene) yog ntau yam thermoplastic polymer dav siv hauv kev lag luam tsheb thiab kev thauj mus los rau pej xeem. Nws yog cov khoom siv amorphous paub txog nws qhov sib npaug zoo ntawm cov khoom siv kho tshuab thiab kev ua haujlwm.
Rau cov khoom siv tsheb npav, cov ntawv ABS tau pom zoo rau ntau yam tseem ceeb:
Impact Resistance:ABS yog ib qho nyuaj heev, muaj peev xwm nqus tau cov kev poob siab tseem ceeb yam tsis muaj kev puas tsuaj -ib qho tseem ceeb rau cov tsheb npav sab hauv xws li cov hnab ntim khoom, cov cuab yeej cuab tam, lossis cov cua txias ducts uas yuav tsum tiv taus cov neeg caij tsheb thiab tsim kua muag.
Thaum tshav kub kub Resistance:Nws tuav cov txheej txheem rigidity thoob plaws qhov kub thiab txias, feem ntau ntawm -20℃thiab 80 degree, kom ntseeg tau tias cov khoom tsis cuam tshuam rau hauv tshav ntuj ncaj qha lossis qhov chaw txias.
Nto tiav:ABS muab qhov du, siab - qhov chaw zoo uas tuaj yeem yooj yim textured, pleev xim rau, lossis laminated nrog cov yeeb yaj kiab zoo nkauj kom haum rau sab hauv kev zoo nkauj ntawm cov tsheb npav niaj hnub.
Machineability:Nws yog ib qho yooj yim los txiav, xyaum, thiab daim ntawv cog lus, tso cai rau kev sib dhos ncaj nraim nrog cov hlau thav duab lossis lwm cov ntaub ntawv sib xyaw.
Lub tshuab nqus tsev tsim txheej txheem
Kev tsim lub tshuab nqus tsev yog cov txheej txheem thermoforming uas hloov cov ntawv yas tiaj tus mus rau hauv peb- qhov seem. Nws yog txoj hauv kev zoo tshaj plaws rau kev tsim cov khoom loj, ntiav cov tsheb npav vim nws cov nqi qis dua piv rau kev txhaj tshuaj molding thiab nws lub peev xwm los tsim cov khoom loj nrog cov nkhaus nkhaus.
Lub hauv paus ntsiab lus ntawm lub tshuab nqus tsev yog ua kom sov ib daim ntawv ABS kom txog thaum nws ua tau zoo (feem ntau ntawm 160℃thiab 180 degree), ces kos nws mus rau hauv pwm siv atmospheric siab. Thaum cov ntawv softened hu rau qhov txias pwm saum npoo, nws solidifies, tuav lub caij nyoog zoo ntawm pwm.
Rau kev lag luam tsheb npav, cov txheej txheem no zoo tagnrho vim tias:
Tsis tshua muaj siab:Tsis zoo li kev txhaj tshuaj molding, lub tshuab nqus tsev siv lub zog clamping tsawg, tso cai rau kev siv tus nqi - zoo aluminium los yog cov pwm sib xyaw ntau dua li cov cuab yeej steel kim.
Loj hom:Nws tuaj yeem tsim cov khoom loj npaum li tag nrho cov tsheb npav qab nthab vaj huam sib luag lossis sab phab ntsa hauv ib lub voj voog.
Tsim Flexibility:Undercuts, tav rau kev txhawb nqa, thiab qhov rau kev sib txuas ntawm cov khoom siv tuaj yeem ua ke rau hauv cov qauv tsim thaum lub sij hawm tsim, txo cov kev ua haujlwm thib ob.
Kev Tsim Khoom Ua Haujlwm ntawm CAD mus rau Kev Tsim Khoom Loj
Kev tsim cov qib siab - zoo ABS cov khoom siv tsheb npav yuav tsum muaj kev ua haujlwm zoo uas txuas nrog cov qauv tsim digital nrog ob txhais tes- ntawm kev ua haujlwm zoo. Cov txheej txheem ua raws tsib theem tseem ceeb:
1. CAD Modeling (SolidWorks)
Txoj kev taug pib nrog kev tsim engineering. Siv SolidWorks, engineers tsim cov ncauj lus kom ntxaws 3D qauv ntawm cov khoom. Cov theem no yog qhov tseem ceeb rau kev ua kom haum nyob rau hauv lub tsheb npav chassis, suav nrog cov khoom siv shrinkage (feem ntau yog 0.5% txog 0.7% rau ABS), thiab tsim cov kaum sab xis (feem ntau yog 3℃txog 5 degree) kom yooj yim tshem tawm ntawm cov pwm tom qab hauv cov txheej txheem. Cov qauv digital ua haujlwm raws li tus qauv tsim qauv rau tag nrho cov kab ntau lawm.
2. Pwm Ua thiab kho kom zoo
Thaum cov qauv tsim digital tiav lawm, cov cuab yeej pib pib. Peb cov kws tsim pwm txawj tsim cov pwm- feem ntau yog los ntawm cam khwb cia txhuas lossis siab - ntom ntom epoxy resin- raws li SolidWorks geometry. Qhov no yog ib theem siab -precision kauj ruam uas craftsmanship yog qhov tseem ceeb. Tom qab thawj pwm yog milled, cov craftsmen nkag mus rau ib theem ntawmnruam sib tsoo thiab kho. Lawv manually polish cov pwm nto mus rau ib daim iav tiav kom ntseeg tau tias ABS qhov kawg muaj qhov tsis zoo. Lawv kuj zoo- kho cov npoo thiab lub tshuab nqus tsev kom ntseeg tau tias huab cua khiav tawm sib npaug. Qhov txheej txheem rov ua dua tshiab ntawm kev sim pwm, txheeb xyuas micro- tsis zoo, thiab tes- ua kom tiav kom ntseeg tau tias cov cuab yeej zoo tag nrho ua ntej kev tsim khoom pib.
3. Kev npaj thiab Extrusion khoom
Concurrent nrog pwm kev loj hlob, raw khoom yog npaj. Thaum peb yuav ABS resin pellets, cov txheej txheem feem ntau pib nrogABS ntawv extrusion. Peb extrude peb cov nplooj ntawv los tswj cov tuab tuab (gauge) xav tau rau cov khoom tshwj xeeb. Rau cov qauv tsheb npav, daim ntawv tuab feem ntau yog li ntawm 2mm txog 6mm. Kev tswj cov extrusion kub thiab yob siab ua kom cov ntawv muaj cov tuab tuab thiab tsis muaj kev ntxhov siab sab hauv, uas yog ib qho tseem ceeb los tiv thaiv webbing lossis tearing thaum tsim.
4. Kev ntsuas thiab ntsuas ntsuas
Ua ntej tag nrho - nplai ntau lawm pib, ib theem kev sim nruj yog ua. Ib daim qauv batch yog tsim siv cov pwm tshiab thiab cov ntawv ABS extruded. Cov khoom yog raug rau ib tug series ntawm kev xeem:
Dimensional raug:Cov qauv tsim tau muab piv rau tus qauv SolidWorks thawj zaug siv CMM (Kev Sib Koom Tes Ntsuas Tshuab) los xyuas kom haum.
Structure Integrity:Cov khoom raug kuaj xyuas qhov cuam tshuam thiab thauj khoom -cov kabmob muaj peev xwm.
Aesthetic Review:Qhov saum npoo yog tshuaj xyuas qhov tsis xws luag xws li "txiv kab ntxwv tev", webbing, lossis cov cim dab dej.
Thaum lub sijhawm no, cov txheej txheem tsis ua haujlwm -lub sijhawm cua sov, ua kom sov, lub tshuab nqus tsev, thiab lub sijhawm ua kom txias- yogkho kom zoo. Yog hais tias qhov kev ntsuam xyuas pom muaj ib qho warping los yog nyias me ntsis, cov pwm tuaj yeem hloov kho ntxiv.
5. Kev tsim khoom loj
Thaum lub sij hawm ntsuam xyuas tau lees paub tias cov pwm, cov khoom siv, thiab lub tshuab teeb tsa ua tau raws li cov qauv nruj nruj rau kev lag luam tsheb npav, cov txheej txheem txav mus raubatch ntau lawm. Cov kab ntau lawm ua haujlwm nrog qib siab ntawm kev sib xws:
Cua sov:ABS cov nplooj ntawv raug thauj mus rau hauv lub tshuab tsim thiab rhuab kom txog thaum lawv sag mus rau qhov pom kev zoo viscosity.
Kev tsim:Daim ntawv yog kos los ntawm cov pwm los ntawm lub tshuab nqus tsev.
Cua txias:Cov kiv cua thiab cov tshuab cua txias txias qhov sib npaug kom ntsuas qhov ntsuas ntawm qhov ntsuas thiab tiv thaiv kev cuam tshuam ntawm shrinkage.
Trimming:Tom qab tsim, qhov chaw yog trimmed siv5-axis CNC carving tshuablos txiav cov contours thiab mounting qhov. Cov neeg ua haujlwm txawj ces ua phau ntawv deburring thiab ua tiav kawg kom paub meej tias haum thiab du npoo.
Kev sib dhos:Cov khoom tiav tiav raug ntxuav, tshuaj xyuas, thiab xa mus rau kev sib dhos zaum kawg uas lawv tau muab tso rau hauv cov qauv tsheb npav.
