CAM Programming thiab Toolpath Strategy

Nrog geometry xauv thiab simulation validated, CAM programming txhais cov qauv tsim rau hauv cov lus qhia tshuab. Txhua qhov contour, hnab tshos, thiab profile ntawm txhua qhov khoom siv tuag xav tau ib lub cuab yeej uas sib npaug ntawm qhov kawg, qhov tseeb qhov tseeb, thiab lub sijhawm voj voog. Qhov no yog qhov uas stamping tsim kev txiav txim siab raws li kev tsim khoom muaj tseeb.

CAM programmers txhais cov tswv yim roughing uas tshem tawm cov khoom ntau sai, tawm hauv Tshuag rau ib nrab- ua tiav thiab hla dhau. Lawv xaiv cutter geometries phim rau cov yam ntxwv tshwj xeeb: pob- lub qhov ntswg kawg mills rau contoured kab noj hniav, tiaj tus kawg mills rau planar nto, thiab me me - txoj kab uas hla cov cuab yeej rau cov ces kaum nruj. Toolpath cov tswv yim zoo li siab -machining ceev nrog cov nti tas li load txo cov txiav quab yuam thiab txuas lub neej ntawm cov cuab yeej, uas tseem ceeb thaum koj ua cov cuab yeej hardened steel ntawm 60+ HRC tom qab kev kho cua sov.

Rau txoj kev tuag cov ntaub ntawv nrog cov kab nkhaus thiab cov kab hauv qab, 5-axis ib txhij ua haujlwm ua kom lub tshuab txiav kom pom zoo rau saum npoo, txo qhov siab scallop thiab txo tes polishing. Yooj yim geometries yuav tsuas xav tau 3-axis ua haujlwm. Tus programmer ua rau cov kev txiav txim siab no los ntawm cov khoom raws li qhov nyuaj ntawm geometry thiab kam rau ua.

Cov txheej txheem hlau stamping tsim kev ua haujlwm los ntawm lub tswv yim mus rau lub tshuab- cov kev pabcuam npaj ua raws li cov lus teev tseg:

1. Ib feem geometry ntshuam thiab xyuas qhov ua tau
2. Kev ua haujlwm ntawm kev sib tsoo, kev sib tsoo, thiab kev sib tsoo
3. Tuag tivthaiv qauv nrog tag nrho parametric associativity
4. Tsim kev simulation, kev twv ua ntej caij nplooj ntoos hlav, thiab tuag ntsej muag them nyiaj
5. Toolpath tiam, simulation pov thawj, thiab tshaj tawm - ua rau CNC

Txhua kauj ruam pub rau tom ntej. Hla kev simulation kom txuag lub sijhawm yuav luag ib txwm raug nqi ntau dua hauv kev ua haujlwm dua. Rushing CAM programming ua rau lub ntsej muag tsis zoo uas yuav tsum tau ua tes ua haujlwm ntau dhau. Cov theem digital yog qhov kev qhuab qhia them cov nyiaj faib nyiaj, vim tias ib zaug koj pib txiav cov hlau, cov kev hloov pauv ua exponentially kim dua. Qhov kev hloov ntawm cov qauv digital mus rau lub cev hlau, qhov tseeb machining ntawm cov khoom siv tuag, yog qhov kev tsim kho qhov nyuaj qhia nws tus kheej kom meej meej.

Hom Stamping Dies thiab Yuav Ua Li Cas Tsim Kev Sib Txawv

Tsis yog tag nrho cov stamping tuag yog tsim tib txoj kev, thiab kev tsim kho complexity txawv nyob ntawm seb hom. Ib qho - chaw nres tsheb blanking tuag yuav xav tau ob peb lub lis piam ntawm machining. Lub 20-chaw nres tsheb nce qib tuag rau daim ntawv thov tsheb stamping tuag tuaj yeem siv sijhawm ntau lub hlis ntawm kev ua haujlwm zoo hla ntau ntau ntawm cov khoom sib cuam tshuam. Kev nkag siab txog hom stamping tuag pab piav qhia vim li cas thiaj tsim cov tswv yim, kam rau ua, thiab cov nqi sib txawv heev thoob plaws cov haujlwm.

Ib leeg -Station Dies vs Compound Dies

Ib leeg- chaw nres tsheb tuag sawv cev rau qeb yooj yim ntawm cov ntawv hlau stamping tuag. Txhua tus xovxwm stroke ua ib qho haujlwm: ib qho khoob, tho, lossis ib daim ntawv. Kev tsim kho yog qhov yooj yim vim tias koj tab tom tsim ib txheej ntawm cov cuab yeej mating nrog ib qho kev txhawj xeeb txog kev sib tw. Yooj yim tuag ua haujlwm yooj yim xws li txiav cov tshuab ntxhua khaub ncaws los yog tho qhov hauv cov brackets.

Compound tuag tsa complexity ib tug notch. Lawv ua ntau txoj haujlwm txiav hauv ib qho hlab ntsha ntawm ib qho chaw nres tsheb. Ib tug raug compound tuag tej zaum yuav blank ib txheej profile thiab tho qhov nyob rau hauv ib txhij. Qhov kev sib tw ntawm kev tsim kho ntawm no yog concentricity. Txhua qhov punch thiab tuag qhib yuav tsum ua raws li qhov tseeb vim tias lawv txhua tus koom nrog cov khoom ntawm tib lub sijhawm. Tolerances nruj, thiab tus tsim tuag yuav tsum suav rau deflection nyob rau hauv ib txhij txiav quab yuam.

Kev sib xyaw tuag mus ib kauj ruam ntxiv los ntawm kev sib xyaw txiav thiab sib sau ua ke hauv ib qho mob stroke. Koj tuaj yeem ua ib qho duab thiab kos rau hauv lub khob hauv ib lub voj voog xovxwm. Kev tsim cov no xav kom cov neeg tsim khoom tuag los tswj ob qho tib si shearing clearances thiab tsim radii nyob rau hauv tib lub cuab yeej, uas yuav tsum tau ceev faj saib xyuas yuav ua li cas cov khoom ntws thaum lub sij hawm ua ke. Tseem, tag nrho cov no yog ib qho - chaw nres tsheb cov cuab yeej. Qhov kev nce siab tiag tiag hauv kev tsim kom muaj kev nyuaj siab tshwm sim thaum koj tsiv mus rau theem cuab yeej uas ua cov sawb los ntawm ntau qhov chaw.

Progressive Die Kev Tsim Kho thiab Chaw Nres Tsheb Sequencing

Progressive tuag yog cov neeg ua haujlwm siab ntawm - ntim stamping. Lawv ua ib tug series ntawm kev khiav hauj lwm nyob rau hauv ntau lub chaw nres tsheb nrog ib tug xovxwm stroke, maj mam hloov ib tug hlau sawb mus rau hauv ib tug tiav ib feem. Raws li MetalForming Magazine piav txog nws, kev tuag zuj zus ua cov haujlwm tseem ceeb ntawm cov ntawv hlau hauv ob lossis ntau qhov chaw ua haujlwm ib txhij, nrog rau cov sawb txav mus rau qhov kev ncua deb ntawm txhua qhov mob stroke los ntawm kev pub mis.

Suab ncaj nraim ntawm txoj cai. Hauv kev xyaum, kev tsim ib qho yog ib qho ntawm cov haujlwm xav tau tshaj plaws hauv cov cuab yeej thiab kev tsim khoom tuag. Nov yog vim li cas:

• Chaw nres tsheb - mus rau - chaw nres tsheb alignment:Txhua qhov chaw nres tsheb yuav tsum tuav txoj haujlwm txheeb ze rau lwm tus hauv microns. Ib qho kev hloov pauv ntawm txawm tias 0.01 hli thoob plaws kaum chaw nres tsheb ua rau qhov tsis kam lees. Lub tshuab tuag tsim txhua qhov chaw nres tsheb nta los ntawm cov ntaub ntawv sib xws thiab txheeb xyuas kev sib raug zoo thoob plaws tag nrho cov txheej txheem tuag.
• Pitch tswj:Pitch yog qhov kev ncua deb ntawm txoj hlua txuas ntxiv ntawm cov hlab ntsha tawg. Txhua qhov tshwj xeeb hauv txhua qhov chaw nres tsheb yuav tsum muaj qhov sib txawv ntawm qhov sib npaug sib npaug. Yog hais tias ib tug piercing punch nyob rau hauv qhov chaw nres tsheb peb zaum 0.02 hli tawm suab los ntawm daim ntawv tooling nyob rau hauv lub yim, cov yam ntxwv yuav tsis ua raws li nyob rau hauv lub tiav ib feem.
• Sawb kev taw qhia thiab lifting:Lub sawb yuav tsum tau noj smoothly los ntawm tag nrho cov chaw nres tsheb yam tsis tau ntes ntawm tsim nta los yog sagging ntawm lifters. Bar lifters, stock guides, thiab relief pockets ntawm cov chaw nres tsheb txhua yam yuav tsum tau machining meej kom tswj tau ib theem pub dav hlau.
• Inter- chaw nres tsheb lub sijhawm:Cov kws tsav dav hlau nkag mus rau hauv qhov pierced yav tas los rau npe rau txoj haujlwm strip ua ntej txhua txoj haujlwm ua haujlwm. Cov pilots no yuav tsum nkag mus thiab thim rov qab hauv kev sib koom tes nrog strippers thiab lifters. Sijhawm yuam kev ua rau muaj kev puas tsuaj los yog tsis tuaj yeem sau npe.

Kev siv qhov tsis zoo thiab zoo bypass notches nyob rau hauv daim ntawv hlau stamping tuag kuj plays lub luag hauj lwm nyob rau hauv kev loj hlob tuag kev tsim kho. Cov kev taw qhia ntawm ntug kab txaij muab cov ntsiab lus siv lub cev rau qhov chaw nyob thiab tso cai rau cov sensors kom pom cov khoom luv luv lossis ntev ntev ua ntej lawv ua kev puas tsuaj. Tsim qhov chaw nres tsheb nrog qhov tseeb geometry thiab txoj hauj lwm yog ib qho ntawm thawj qhov kev sib tw - cov haujlwm tseem ceeb hauv qhov tuag.

Kev tsim kho ntawm steel stamping tuag rau cov ntawv thov nce qib kuj xav tau qhov tshwj xeeb sib xws hauv kev tsim khoom. Txhua qhov punch, tuag ntxig, thiab rov qab phaj yuav tsum yog hauv av tiaj tus thiab sib npaug. Kev taw qhia pins thiab bushings yuav tsum tuav cov khau sab sauv thiab qis hauv kev sib dhos hauv cov xovxwm dynamic. Kev vam meej tuag tsis yog ib qho kev sau ntawm chaw nres tsheb xwb; nws yog ib qho kev sib koom ua ke txhua yam uas txhua yam cuam tshuam rau kev ua haujlwm ntawm txhua lwm yam.

Hloov Tuag rau Loj lossis tob-Drawn Parts

Hloov stamping siv txoj kev sib txawv. Hloov chaw ntawm kev khaws cov khoom txuas nrog rau cov khoom thauj khoom, cov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob Txoj kev no haum rau qhov loj, sib sib zog nqus- rub cov plhaub, thiab cov duab geometry uas tsis tuaj yeem txuas nrog ib lub strip thaum tsim.

Lub tsev hloov tuag qhia nws tus kheej complexity. Txhua qhov chaw nres tsheb ua haujlwm raws li cov cuab yeej ywj pheej, tab sis txhua tus yuav tsum sib koom ua ke nrog cov kev hloov pauv. Gripper txoj hauj lwm, ib feem kev taw qhia, thiab chaw nres tsheb - mus rau - chaw nres tsheb qhov sib txawv yuav tsum phim lub tshuab hloov tshuab raws nraim. Automotive stamping tuag rau cov qauv ntawm lub cev vaj huam sib luag, lub qhov rooj sab hauv, thiab qhov sib sib zog nqus-cov vaj tse sib sib zog nqus feem ntau siv cov qauv hloov pauv vim tias qhov loj me thiab kos qhov tob tshaj qhov uas cov sawb txuas ntxiv tuaj yeem ua tau.

Cov lus hauv qab no sib piv yuav ua li cas kev tsim kho yuav tsum sib txawv ntawm cov hom stamping tuag:

Kev dhia los ntawm ib qho - chaw nres tsheb mus rau kev txhim kho lossis hloov kev tsim kho tsis yog ib qho teeb meem ntawm kev ntxiv chaw nres tsheb. Nws yog qhov hloov pauv tseem ceeb hauv koj li cas koj npaj, tshuab, thiab siv tau qhov tuag. Txhua qhov chaw nres tsheb ntxiv muab cov lej ntawm qhov tseem ceeb, tus lej ntawm cov khoom uas xav tau sub-micron raug, thiab tus naj npawb ntawm kev sib cuam tshuam uas yuav tsum ua haujlwm hauv kev hais kwv txhiaj. Qhov kev nce qib hauv qhov yuav tsum tau muaj tseeb ua rau cov khoom siv xaiv tuag cov neeg tsim khoom ntsib thaum xaiv cov cuab yeej steels uas yuav tsim cov pob txha ntawm txhua qhov khoom.

Xaiv Cov Cuab Yeej Hlau Raws Li Qhov Koj Ua Stamping

Kev tuag tsuas yog ua tau ntev npaum li cov hlau nws yog tsim los ntawm, thiab qib yog nyob ntawm yuav luag tag nrho ntawm cov ntawv hlau uas koj npaj yuav stamp. Cov hlau me me, stainless, aluminium, thiab siab - alloys muaj zog txhua qhov sib txawv ntawm cov cuab yeej siv. Qee qhov hnav cov npoo maj mam dhau los ntawm kev puas tsuaj. Lwm tus xa cov kev cuam tshuam loj heev uas nti cov hlau tsis huv. Xaiv cov khoom siv hlau stamping rau punches, tuag blocks, thiab tsim cov ntawv ntxig yam tsis xav txog cov khoom stamped zoo li xaiv cov log tsheb yam tsis paub txog txoj kev.

Cov cuab yeej Steel Qib thiab lawv cov ntawv thov stamping

Tsib yam khoom siv npog feem ntau ntawm cov khoom siv tuag siv hauv kev tsim khoom stamping. Txhua qhov chaw nyob sib txawv ntawm qhov hardness -toughness spectrum, thiab txhua tus haum rau ib hom kev ua tsis tiav.

D2 cuab yeej steelyog lub neej ntawd xaiv thaum abrasive hnav txwv lub cuab yeej lub neej. Nws cov ntsiab lus chromium carbide siab ua rau txiav cov npoo ntse dhau kev ua haujlwm ntev. Rau siab - ntim blanking thiab tho ntawm stamped steel thiab coated cov ntaub ntawv, D2 muab qhov zoo tshaj plaws ntug tuav. Txawm li cas los xij, nws tsis muaj qhov toughness kom muaj sia nyob rau qhov hnyav, yog li nws tsis yog qhov zoo tagnrho rau tuab - ntsuas qhov chaw nres tsheb uas muaj kev poob siab.

A2 cuab yeej steelua haujlwm zoo tshaj plaws thaum tsis muaj ib hom kev ua tsis tiav kom meej meej dominates. Nws sib npaug hnav tsis kam nrog lub zog txaus los tswj cov kev cuam tshuam nruab nrab, ua rau nws yog qhov kev xaiv zoo rau kev vam meej tuag qhov twg ntau qhov chaw muaj kev sib xyaw ntawm kev hnav, thauj khoom, thiab kev cuam tshuam cyclic. Rau nruab nrab- ntim ntau lawm hauv qab 1,000,000 hits, A2 feem ntau muab tus nqi ntau tshaj - ua haujlwm tau zoo.

S7 cuab yeej steelqhov tseem ceeb toughness tshaj txhua yam. Thaum punches nti los yog tawg nyob rau hauv kev cuam tshuam rov qab, tshwj xeeb tshaj yog nyob rau hauv hnyav - ntsuas stamping los yog chaw nres tsheb nrog hnyav tho loads, S7 absorbs cyclic kev nyuaj siab uas yuav puas siab dua -carbide qib. Nws khiav ntawm qis hardness (56-58 HRC) tab sis tiv taus qaug zog tawg zoo dua li D2 lossis M2.

M2 siab-ceev steelsau qhov sib txawv qhov twg ob qho tib si hnav thiab compressive load ua rau tsis ua hauj lwm. Punches uas yuav tsum tswj hwm ntug geometry nyob rau hauv siab txhawb nqa siab tau txais txiaj ntsig los ntawm M2 kev sib xyaw ntawm hardness (60-65 HRC) thiab compressive zog. Piv nrog D2, nws tiv taus deformation zoo dua. Piv nrog rau S7, nws tuav lub ntsej muag ntev dua.

Tungsten carbideinserts xa cov hnav tsis kam mus txog 30 npaug ntau dua li cov cuab yeej siv hlau. Lawv tuav qhov tseeb qhov tseeb ntawm ntau lab lub voj voog, uas ua rau lawv tsuas yog qhov kev xaiv ua tau zoo rau ultra-siab- daim ntawv thov ntim lossis thaum stamping cov ntaub ntawv muaj zog heev. Kev lag luam tawm: carbide yog nkig, kim, thiab xav tau kev sib tsoo tshwj xeeb lossis EDM kom zoo. Nws tsis tuaj yeem nqus cov khoom hnyav los yog cuam tshuam yam tsis muaj kev pheej hmoo ntawm kev puas tsuaj puas tsuaj.

Yuav Ua Li Cas Stamped Material Changes Die Design Choices

Cov ntawv hlau khiav los ntawm qhov tuag dictates cov qib twg nyob rau hauv txoj haujlwm twg. Xav txog peb yam xwm txheej:

Stainless hlau stampingnthuav tawm qhov kev sib tw dual. Austenitic qib zoo li 304 thiab 316 yog ob qho tib si abrasive thiab nquag hnav cov nplaum (galling). Cov khoom ua hauj lwm- hardens sai heev thaum lub sij hawm tsim, uas ua rau kom txiav quab yuam thiab accelerates ntug deterioration. Stainless stamping xav tau siab- hardness tooling, feem ntau D2 lossis carbide inserts ntawm cov chaw txiav, ua ke nrog polished nto thiab tiv thaiv -galling coatings los tiv thaiv cov khoom tuaj ntawm cov hlau.

Aluminium stamping qhov chawzoo li nws yuav tsum yooj yim rau kev siv vim tias cov khoom yog mos. Hauv kev xyaum, cov txheej txheem aluminium stamping tsim nws tus kheej cov teeb meem. Aluminium muaj lub siab nyiam ua raws li cov cuab yeej steel, txhim kho ntawm lub ntsej muag punch thiab tuag radii kom txog rau thaum ib feem zoo degrades. Thaum ua haujlwm nrog stamped aluminium ntawv hlau, cov neeg tsim khoom tuag ua qhov tseem ceeb ntawm qhov tiav thiab txheej txheej xaiv ntawm cov tawv tawv.
