Sheet Hlau Compatibility Nrog 3D Printed Tooling

Koj cov ntaub ntawv tuag tsuas yog qhia ib nrab ntawm zaj dab neeg. Lwm ib nrab? Yam koj tab tom ua tiag tiag. Cov pa roj carbon- fiber ntau nylon tuag uas breezes los ntawm 0.5 hli txhuas yuav tawg ntawm nws thawj zaug ntsib nrog 1.0 hli stainless hlau. Daim ntawv hlau nws tus kheej - nws hardness, thickness, thiab elastic cwj pwm - dictates seb 3D luam ntawv tuag yog ib tug tswv yim sheet hlau ua cuab yeej los yog ib daim ntawv qhia rau nkim sij hawm thiab cov yas tawg.

Yuav ua li cas Sheet Hlau Hardness cuam tshuam tuag Feasibility

Hardness txiav txim siab npaum li cas lub zog ntawm daim ntawv resists thaum lub sij hawm tsim, thiab lub zog ntawd hloov ncaj qha rau hauv koj cov tuag. Cov hlau mos zoo li tuag- mos tooj liab thiab 1100-series aluminium yield ntawm ib ncig ntawm 35-70 MPa. Cov hlau me me (AISI 1018/1020) dhia mus rau 250-350 MPa yield zog. Stainless hlau (304/316) thawb mus ntxiv, nrog cov khoom muaj zog ntawm 200-290 MPa nyob rau hauv annealed mob tab sis ho ua hauj lwm ntau dua - hardening tus nqi uas nce load raws li txoj kev loj hlob. Siab -lub zog steels - zoo li DP980 thiab boron steels siv hauv kev siv tsheb - ncav cuag qhov muaj zog tshaj 600 MPa.

Qhov no txhais li cas rau kev xaiv tuag? Ib lub polymer tuag tuaj yeem tswj cov txheej txheem tsim los ntawm cov khoom siv aluminium vim tias daim ntawv yields ua ntej tuag muaj kev ntxhov siab txaus ntshai. Cov hlau me me yuav tsum muaj zog ntau dua los ua kom deform, thawb cov polymer tuag rau lawv cov kev txwv txawm tias ntawm cov ntsuas nyias. Cov hlau tsis muaj steel thiab siab - lub zog steels tsim tsim cov rog uas muaj peev xwm ntau dua polymer compressive hauv yuav luag txhua qhov xwm txheej.

Cov ntsiab lus carbon ntau dua hauv cov hlau los yog ntau dua hardness hauv txhuas txo cov ductility thiab formability, ua kom lub zog yuav tsum tau thiab qhov tsawg kawg nkaus lub vojvoog uas tuaj yeem tsim tau. Qhov kev quab yuam ntawd yog qhov uas thawb koj los ntawm cov cuab yeej polymer rau hauv cov hlau - luam tawm lossis cov pa tuag.

Ntsuas Thickness thiab tsim kev sib raug zoo

Thickness multiplies yuam kev uas tsis yog -linearly. Doubling daim ntawv thickness tsis tsuas yog ob npaug rau tonnage - nws roughly quadruples nws rau dabtsi yog khoov kev khiav hauj lwm, txij li thaum tsim quab yuam scales nrog rau cov square ntawm cov khoom thickness nyob rau hauv feem ntau xovxwm hlau sib sib npaug. Ib qho polymer tuag uas yooj yim tsim 0.5 hli txhuas tuaj yeem ua tsis zoo ntawm 1.5 hli ntawm tib cov khoom, txawm tias hom hlau tsis tau hloov.

Nov yog ib txoj hauv kev los xav txog nws. Sheet hlau gauges feem ntau siv nyob rau hauv stamping ntau yam ntawm roughly 0.005 mus rau 0.249 ntiv tes (li 0.13 mus rau 6.3 hli). Ntawm qhov kawg nyias, tsim cov rog nyob qis txaus rau cov cuab yeej polymer hla feem ntau cov hlau. Ntawm qhov kawg, txawm tias txhuas phaj xav tau cov hlau tsuas yog - cov ntawv luam tawm lossis cov hlau tawv tawv tuaj yeem txhawb nqa.

Qhov tseem ceeb tshaj plaws rau polymer FDM tuag zoo li tsaws ib ncig:

• Aluminium alloys:mus txog 1.0-1.5 hli (nyob ntawm alloy hardness thiab geometry complexity)
• Tooj thiab tooj dag:mus txog 0.8-1.0 mm
• Me me steel:mus txog 0.5-0.8 mm (nrog siab -strength composite filaments)
• Stainless hlau:generally not feasible with polymer dies, regardless of infill density

Tshaj li cov kev cai no, cov compressive thiab shear quab yuam thaum lub sij hawm tsim ntau tshaj qhov txawm tias 100% infill carbon- fiber ntau nylon tuaj yeem tiv taus yam tsis muaj qhov sib tsoo lossis txheej delamination. Koj yuav pom qhov tuag pib deform ua ntej daim ntawv ua - pom tseeb tias koj tau dhau lub peev xwm ntawm cov cuab yeej.

Caij nplooj ntoos hlav-Cov tswv yim them nyiaj rov qab

Txhua qhov tsim cov hlau txuas rov qab mus rau nws cov duab qub qub thaum nias lub zog tawm. Caij nplooj ntoos hlav-rov qab yog qhov tso tawm ntawm elastic strain, thiab nws scales ncaj qha nrog cov khoom yield zog. Cov txhuas mos tuaj yeem rov qab 1-2 degrees ntawm qhov khoov yooj yim, thaum stainless hlau lossis siab -lub zog hlau tuaj yeem rov qab 5-10 degrees lossis ntau dua nyob rau hauv zoo tib yam geometry.

Rau 3D luam tawm tuag, lub caij nplooj ntoos hlav- rov qab them nyiaj txhais tau tias dhau - khoov - tsim cov tuag los ua daim ntawv dhau los ntawm nws lub hom phiaj lub kaum ntse ntse kom nws rov qab mus rau qhov tseeb. Ib daim ntawv hlau ua haujlwm nrog 2 degrees ntawm lub caij nplooj ntoos hlav-rov qab yuav tsum muaj lub kaum sab xis ntawm qhov tsawg kawg yog 2 degrees sharper dua li lub hom phiaj txhawm rau txhawm rau txhawm rau txhawm rau rov qab elasticity. Raws li lub vojvoog nce ntxiv rau cov khoom tuab, lub caij nplooj ntoos hlav- rov qab nce ntxiv, qee zaum tseem ceeb.

Cov tswv yim them nyiaj sib txawv los ntawm hom tuag:

• Polymer tuag:Txij li thaum lawv pheej yig thiab ceev kom rov luam dua, koj tuaj yeem rov ua dua sai. Luam tawm, daim ntawv, ntsuas lub caij nplooj ntoos hlav- rov qab lub kaum sab xis, tom qab ntawd kho koj tus qauv CAD thiab rov luam dua. Qhov kev sim no -thiab- yuam kev mus kom ze ua haujlwm tau zoo vim tias txhua qhov kev rov ua dua raug nqi tsawg tsawg thiab cov khoom siv.
• Hlau - luam tawm tuag:Iterate nyob rau hauv polymer ua ntej rau ntsia hlau caij nplooj ntoos hlav- rov qab them nyiaj, ces cog lus rau ib tug hlau luam nrog lub kho geometry. Reworking a metal-luam tuag yog kim, yog li tau txais lub kaum sab xis ua ntej tseem ceeb.
• High-yield- cov ntaub ntawv muaj zog:Xav txog kev tshem cov geometry nrog cov kaum sab xis ntawm 78 lossis 73 degrees, uas tso cai rau kev nkag mus tob tob kom kov yeej lub caij nplooj ntoo hlav- rov qab yam tsis muaj kev cuam tshuam ntawm lub ntsej muag tuag thiab cov khoom siv.

Cov kev taw qhia ntawm cov ntawv hlau tseem cuam tshuam rau ob qho tib si tsim lub zog thiab lub caij nplooj ntoos hlav- rov qab. Ua nrog cov nplej (longitudinal) yuav tsum tau muaj zog dabtsi yog khoov vim ductility stretches nkag mus rau hauv cov kev taw qhia, tab sis longitudinal dabtsi yog khoov ua rau muaj kev pheej hmoo ntawm nto tawg thiab xav tau ib tug loj khoov vojvoog. Kev sib sau thoob plaws cov nplej (transverse) nce tonnage tab sis lees txais nruj dua radii. Thaum tsim lub 3D luam ntawv tuag, xyuas seb koj qhov khoob puas yuav taw qhia los yog tawm tsam cov nplej, thiab loj koj qhov tuag lub vojvoog thiab lub kaum sab xis kom haum.

CAD Design thiab Additive Manufacturing Considerations

Thaum koj mus cuag cad tsim rau stamping tuag ua hauj lwm nyob rau hauv ib tug additive ntsiab lus, koj nyob nraum tsim rau ob qhov tseeb ib txhij: txoj kev tsim thiab cov txheej txheem luam ntawv. Tsis quav ntsej ib qho, thiab koj yuav xaus nrog kev tuag uas tsis tuaj yeem luam tawm kom huv lossis tsis tuaj yeem muaj sia nyob ntawm xovxwm.

Phab ntsa thickness thiab loj.Polymer stamping tuag xav tau ntau ntau tshaj li qhov koj xav tau. Qhov tsawg kawg nkaus phab ntsa thickness rau FDM tooling yuav tsum yog 8-12 hli nyob rau hauv load-cov kabmob. Nyias hla- seem hauv qab 2 hli deform sai nyob rau hauv compressive load thiab kub, xws liKev tshawb nrhiav Formlabs lees paub- nto thickness tsawg dua 1-2 hli yuav deform nrog tshav kub nyob rau hauv daim ntawv thov. Rau cov hlau- luam tawm tuag, 3-5 hli phab ntsa ntu feem ntau muab qhov nruj txaus, txij li cov khoom nws tus kheej nqa ntau dua loads ib cheeb tsam.

Daim duab kaum.Xws li 3-5 degrees ntawm cov cua ntsawj ntshab ntawm tag nrho cov phab ntsa ntsug ntawm cov kab noj hniav tuag. Qhov no ua haujlwm rau ob lub hom phiaj: nws pab txhawb ib feem ejection tom qab tsim (tiv thaiv cov ntawv hlau los ntawm kev xauv hauv qhov tuag) thiab txhim kho kev luam tawm los ntawm kev txo cov overhangs uas xav tau kev txhawb nqa. Rau cov polymer tuag tshwj xeeb, cov kaum sab xis txo cov demolding rog uas tuaj yeem nti lossis tawg cov cuab yeej nto.

Cov tswv yim txhawb zog.Polymer tuag tsis tshua ua hauj lwm raws li cov cuab yeej standalone monolithic nyob rau hauv xovxwm loads. Tsim koj qhov tuag los ua ke nrog lub phaj nraub qaum - feem ntau yog ib qho txhuas lossis hlau phaj uas faib cov quab yuam hla tus tuag lub ntsej muag tom qab. Npaj recesses los yog ntsia liaj qhov rooj qhov nyob rau hauv koj tus qauv CAD rau fastening cov luam ntawv tuag rau no thaub qab qauv. Qee tus neeg tsim qauv kos cov hlau dowels lossis bolts nyob rau hauv cov ntawv luam tawm los ntawm ncua ib nrab - luam tawm thiab ntxig cov khoom siv, tsim cov cuab yeej sib xyaw uas ua haujlwm ntau dua li cov khoom siv polymer ib leeg.

Infill qauv rau 3d luam ntawv tooling.Qhov no yog qhov kev txiav txim siab hauv geometry ncaj qha txiav txim lub neej tuag. Peb tus qauv dominate cov cuab yeej siv:

Print orientation:Orient cov tuag kom sib sau ua ke compress txheej ua ke es tsis txhob sim tev lawv sib nrug. Rau ib tug V- tuag, qhov no txhais tau tias luam ntawv nrog cov kab noj hniav uas tig mus thiab cov khaubncaws sab nraud povtseg sib npaug rau lub ntsej muag tuag. Txheej delamination nyob rau hauv tensile loads yog feem ntau tsis ua hauj lwm hom nyob rau hauv FDM tooling - kom zoo orientation tiv thaiv nws.

Perimeter suav:Ua kom cov phab ntsa sab nrauv kom 4-6 perimeters yam tsawg kawg nkaus. Cov khoom siv sab nrauv no nqa feem ntau ntawm compressive loads thiab tiv thaiv sab hauv infill los ntawm kev sib cuag ncaj qha nrog cov ntawv hlau. Ntau qhov perimeters kuj txhim kho qhov durability.

Tom qab ua tiav 3d luam ntawv tuag txuas qhov sib txawv ntawm cov ntawv luam tawm thiab cov cuab yeej ua haujlwm:

1. Txhawb kev tshem tawm thiab ntxuav:Tshem tag nrho cov khoom txhawb nqa, them nyiaj tshwj xeeb rau kev tsim cov chaw. Ib qho nubs lossis cov cim tseem tshuav yuav xov tooj rau hauv koj qhov chaw tsim.
2. Nto finishing:Xuab zeb tsim nto los ntawm kev loj hlob grits - 120 mus rau 220 rau 400 - kom tshem tawm cov txheej txheej. Rau cov polymer tuag, ib txheej epoxy rau ntawm qhov chaw tsim cov tawv nqaij tawv uas tiv taus hnav ntev dua. Rau SLA tuag, xov xwm blasting nrog iav hlaws smooths saum npoo thiab tuaj yeem txhim kho cov khoom siv kho tshuab.
3. Dimensional pov thawj:Ntsuas qhov loj me nrog calipers lossis CMM. Sib piv rau koj tus qauv CAD thiab sau ntawv sib txawv. Qhov tseeb qhov tseeb rau FDM cov cuab yeej khiav ± 0.1-0.3 hli; SLA ua tiav ± 0.05 hli. Yog tias cov txheej txheem tseem ceeb tawm ntawm qhov tshwj xeeb, tshuab lossis xuab zeb lawv ua siab ntev siv cov nyiaj pub dawb uas koj tau npaj ua ntej.
4. Kev kho cua sov (hlau tuag nkaus xwb):Hlau -cov ntawv luam tawm yuav tsum muaj kev ntxhov siab thiab feem ntau muaj hnub nyoog- tawv. Maraging steel, piv txwv li, xav tau kev laus ntawm kwv yees li 490℃rau 6 teev kom ncav cuag tag nrho hardness (50-55 HRC). Hla cov kauj ruam no thiab koj cov hlau tuag yuav ua haujlwm tsis zoo.

Xovxwm Teeb thiab Thawj Tshooj Cai

Koj qhov tuag tau luam tawm, tiav, thiab ntsuas qhov ntev. Kev nkag mus rau hauv xovxwm kom raug txiav txim siab seb qhov kev ntaus thawj zaug ua rau qhov zoo lossis cov cuab yeej puas.

Backing phaj integration:Tsis txhob tso lub polymer tuag ncaj qha rau ntawm lub txaj xovxwm yam tsis muaj hlau thaub qab phaj. Lub phaj faib ram quab yuam hla tag nrho cov hneev taw tuag, tiv thaiv kev sib tsoo hauv zos. Siv cov av tiaj tus txhuas phaj ntawm qhov tsawg kawg nkaus 6 hli tuab rau qis- daim ntawv thov tons, lossis steel phaj rau txhua yam siab dua 10 kN. Ruaj ntseg tuag rau lub phaj nraub qaum nrog bolts, clamps, lossis lub hnab ntim rov qab uas tiv thaiv kev txav mus los thaum lub sijhawm tsim.

Kev sib tw:Mounting centering pins los yog siv cov ntawv sau npe sau rau hauv qhov tuag halves kom paub meej cov punch -rau - tuag alignment. Misalignment me me li 0.5 hli ua rau cov khoom tsis sib xws uas ua rau kom tuag hnav ntawm ib sab thiab ua rau qhov tsis sib xws.

Kev ceev thiab quab yuam:Pib conservatively. Txo cov xovxwm ceev mus rau 50% ntawm qhov koj xav siv nrog cov cuab yeej siv. Polymer tuag tsis zam qhov cuam tshuam rau txoj kev hardened steel ua - qeeb ram speeds tso cai rau cov ntaub ntawv los nqus cov loads zuj zus es tsis muaj kev poob siab. Rau tib lub laj thawj, txo qis tonnage mus rau qhov tsawg kawg nkaus uas ua tiav kev ua tiav, tom qab ntawd nce ntxiv yog tias qhov tsis zoo tag nrho.

Thawj tsab xov xwm tshuaj xyuas:Ua ib feem, tshem nws, thiab ntsuas nws tawm tsam koj lub hom phiaj qhov ntev. Tshawb xyuas:

• Caij nplooj ntoos hlav- rov qab sib txawv (piv lub kaum ntse ntse rau lub hom phiaj)
• Deg cov cim los yog khawb kis los ntawm cov kab tuag
• Dimensional raug ntawm cov yam ntxwv tseem ceeb
• Txhua yam cim ntawm kev tuag deformation ( ci iab me ntsis, compression cim rau ntawm qhov tuag)

Yog tias lub caij nplooj ntoos hlav- rov qab dhau qhov kev cia siab, kho cov duab geometry raws li cov tswv yim them nyiaj tau tham ua ntej thiab rov luam dua. Yog tias cov cim saum npoo tshwm, ntxiv xuab zeb lossis txheej txheej daws lawv. If the die shows compression marks after a single hit, your material choice or infill density isn't adequate for the forming forces involved - step up to a stiffer material class rather than reprinting at the same spec.

Kho lub voj voog:Tshawb xyuas qhov chaw tuag txhua 10-20 qhov chaw rau cov cuab yeej polymer, txhua 500-1,000 qhov chaw rau hlau- luam tawm tuag. Hnav cov qauv qhia lawv tus kheej li dulling deg, ntug puag ncig, lossis micro- tawg ntawm kev ntxhov siab. Lub teeb sanding nruab nrab ntawm kev khiav tuaj yeem txuas ntxiv lub neej ntawm polymer tuag, thaum hlau tuag tau txais txiaj ntsig los ntawm ntu ntu ntawm kev sib sau ntawm qhov chaw. Taug qab qhov dav dav ntawm koj qhov chaw tsim - thaum kev ntsuas mus txog qhov kev txwv tsis pub dhau, qhov tuag tab tom txog qhov kawg ntawm lub neej.

Qhov kawg no -rau- txheej txheem kawg - tsim, luam tawm, ua tiav, teeb tsa, daim ntawv, tuav - feem ntau compresses rau 24-72 teev rau polymer tuag thiab 1-2 lub lis piam rau hlau- luam tawm tuag nrog rau kev kho cua sov. Muab piv rau 4-8 lub lis piam rau kev siv cov cuab yeej siv ua ke, thiab lub sij hawm kom zoo dua yuav pom tseeb. Tab sis kev ceev tsuas yog qhov tseem ceeb yog tias qhov tuag tau ntev txaus los ua kom tiav koj cov kev tsim khoom, uas ua rau cov lus nug tseem ceeb ntawm cov cuab yeej no ua li cas thiab koj tuaj yeem ua dab tsi los tiv thaiv nws.
