10. Kev tshuaj xyuas zaum kawg thiab validation

Txhua kauj ruam tsim ntawm ib qho ua ntej nws. Hla ib qho, maj mus rau lwm qhov, thiab qhov tshwm sim tshwm sim sai sai - qhov ntev drift, hnav ntxov ntxov, nce cov nqi seem. Cia peb taug kev los ntawm cov theem uas muaj kev cuam tshuam loj tshaj plaws ntawm kev tuag tiav thiab ib feem zoo.

Los ntawm Lub Tswv Yim rau CAD thiab CAE Simulation

Ua ntej cov hlau raug txiav txim, ib qhov kev tsim khoom tuag pib nrog cov lus nug: qhov no puas tuaj yeem raug stamped li tsim? Kev tsom xam Feasibility thiab Design for Manufacturability (DFM) tshuaj xyuas cov teeb meem thaum cov kev hloov pauv tseem pheej yig. Pab neeg ua haujlwm engineering ntsuas ib feem geometry, hom khoom thiab thickness, kam rau ua, thiab xav tau ntau lawm ntim. Cov teeb meem tshwm sim nyob rau theem no suav nrog qhov tsis txaus khoov radii, qhov nyob ze ze rau qhov chaw tsim, muaj kev pheej hmoo ntawm lub caij nplooj ntoos hlav uas yuav cuam tshuam qhov flatness, thiab strip layout txwv uas ua rau kev txhim kho stamping impractical yam tsis muaj kev kho me me geometry.

Kev ntes cov teeb meem no thaum DFM raug nqi yuav luag tsis muaj dab tsi. Kev ntes lawv thaum lub sijhawm sim ua haujlwm raug nqi ntau txhiab -thiab ncua sijhawm ntau lawm.

Nrog rau qhov ua tau tau lees paub, qhov project txav mus rau hauv CAD-raws li tus qauv tsim. Cov kws ua haujlwm ua qauv ua tiav kev sib dhos ua tiav- chaw nres tsheb, kev tsim cov kab ke, kev tsav tsheb, kev xuas nrig ntaus thiab tuag tshem tawm, thiab tag nrho cov txheej txheem kev npaj. Cov cuab yeej zoo liSolidWorkstso cai rau kev cuam tshuam kev txheeb xyuas thiab kev txheeb xyuas qhov tseeb thoob plaws tag nrho lub rooj sib txoos ua ntej machining pib.

Qhov sib txawv tiag tiag hauv kev tsim vaj tsev niaj hnub tuag, txawm li cas los xij, yog computer -aided engineering (CAE) simulation. Finite element tsom xam (FEA) cov qauv yuav ua li cas cov hlau yuav coj raws li lub zog xovxwm- kwv yees kev faib tawm kev ntxhov siab, cov khoom siv thinning, thiab ntws ntawm cov hlau los ntawm kev ua kab noj hniav. Kev twv ua ntej Springback yog qhov tseem ceeb tshwj xeeb rau cov qib siab siab - lub zog steels thiab aluminium alloys, qhov twg elastic rov qab los ntawm kev sib sau tuaj yeem rub cov kaum sab xis ob peb degrees tawm ntawm nominal.

Raws likev lag luam tshawb fawb ntawm tuag simulationqhia tau hais tias, kev ntseeg siab springback twv yuav tsum muaj kev mob siab rau hauv kev ua qauv txhua yam ntawm cov txheej txheem stamping: tuag tej yam kev mob xws li pad bearing thiab sidewall clearances, txheej txheem tsis xws li binder tonnages thiab cushion pin qhov chaw, yog cov khoom characterization los ntawm nro- kev ntsuam xyuas compression, thiab muaj tseeb kev sib txhuam qauv. Qhov kev simulation yuav tsum sawv cev rau cov xwm txheej raws nraim li lawv yuav tshwm sim thaum lub sijhawm tsim khoom-tsis yog qhov kev kwv yees zoo tshaj plaws. Thaum simulation ua tiav lawm, nws txheeb xyuas seb lub caij nplooj ntoos hlav tuaj yeem txo qis los ntawm cov txheej txheem hloov pauv, tswj los ntawm kev hloov kho, lossis them nyiaj los ntawm kev txhob txwm tshaj - khoov ntawm qhov chaw tuag.

Qhov no virtual validation theem yog qhov uas kim heev lub cev iterations tau compressed. Lub chaw tsim khoom tuag uas nqis peev ntau hauv CAE simulation txo qhov kev sim ua haujlwm, ntes cov teeb meem ua ntej txiav cov hlau, thiab xa cov cuab yeej uas khiav ze rau qhov tshwj xeeb los ntawm thawj zaug nias stroke.

Precision Machining thiab kho cua sov

Nrog rau kev tsim qauv siv digitally, lub cev tsim khoom ntawm cov khoom tuag pib. Qhov no yog qhov chaw machining tuag Cheebtsam rau cov kev qhia tshwj xeeb txiav txim siab seb lub hom phiaj tsim puas muaj sia nyob ntawm kev hloov mus rau cov khoom siv ntau lawm.

CNC machiningua haujlwm tshem tawm cov khoom siv ntau ntau-roughing tawm cov blocks tuag, punch phaj, thiab cov khoom vaj huam sib luag kom ze rau -net shape. Multi-axis CNC cov chaw tuaj yeem tshuab 3D contours rau kev tsim kab noj hniav, tab sis qhov tseeb tiag ua haujlwm feem ntau tshwm sim nyob rau theem tom ntej.

Hlau EDM (Electrical Discharge Machining)yog tus neeg ua haujlwm rau nruj- cov yam ntxwv ua siab ntev. Siv cov hlua hluav taws xob nyias nyias los txiav los ntawm cov hlau tawv tawv, xaim EDM ua tiav qhov tseeb uas cov pa milling tsis tuaj yeem sib xws - tsim cov punch thiab tuag clearances, intricate contours, thiab nplua qhov ntsuas hauv microns. Rau kev vam meej cov khoom sib txuas uas muaj ntau lub punch- rau- kev sib raug zoo tuag yuav tsum tau tuav ib txhij, xaim EDM yog qhov tseem ceeb.

Jig sib tsoo thiab profile sib tsoonqa qhov chaw tseem ceeb mus rau qhov kawg qhov ntev, tshwj xeeb tshaj yog tom qab kev kho cua sov qhia me ntsis kev hloov pauv. Kev sib tsoo tiav rov ua dua geometry mus rau qhov tseeb kam rau ua tau teev tseg hauv kev tsim.

Kev kho cua sov yog qhov uas cov khoom siv tuag tau qhov hardness thiab hnav tsis kam uas txiav txim siab ntev npaum li cas cov cuab yeej yuav kav ntev npaum li cas. Peb txheej txheem dominate tuag manufacturing:

• Hardening:Cov cuab yeej cua sov steel saum toj no nws qhov kev hloov pauv kub (austenitizing) thiab tom qab ntawd nrawm nrawm nws los ua martensite- cov qauv crystalline uas xa cov hardness siab tshaj plaws. Rau cov hlau uas muaj cov ntsiab lus carbon saum toj no 0.3%, cov txheej txheem no tuaj yeem ua rau muaj qhov tawv tawv, tab sis nws kuj qhia txog brittleness.
• Tempering:Reheating hardened steel mus rau qhov ntsuas kub - feem ntau nruab nrab ntawm100 thiab 700 degrees Celsius- txhawm rau txo brittleness thiab ua tiav qhov xav tau sib npaug ntawm hardness thiab toughness. Qhov sib txawv tempering kub tsim cov yam ntxwv ntawm kev ua haujlwm sib txawv: qis qis khaws cov hardness ntau dua rau kev siv txiav, thaum kub siab dua nyiam cov tawv tawv rau cov khoom raug cuam tshuam rau kev thauj khoom.
• Nitriding:Diffuse nitrogen rau hauv cov hlau nto ntawm ib ncig ntawm 500-530 degrees Celsius los tsim ib txheej txheej tawv heev yam tsis muaj quenching kauj ruam. Nitrided nto tiv taus hnav thiab galling tshwj xeeb tshaj yog zoo, ua qhov kev kho mob no muaj txiaj ntsig rau kev tsim cov chaw tuag uas hu rau cov ntawv hlau hauv qab siab. Tsis zoo li los ntawm-hardening, nitriding tuav lub toughness ntawm cov khoom tseem ceeb thaum hardening tsuas yog sab nrauv cheeb tsam.

Qhov kev xaiv ntawm cov txheej txheem no- thiab cov kev txwv tshwj xeeb hauv txhua qhov - nyob ntawm seb cov khoom siv tuag. Txiav punches xav tau qhov siab tshaj plaws ntawm ntug hardness, yog li lawv feem ntau tau txais tag nrho hardening ua raws li qis - kub tempering. Kev tsim cov khoom siv tau txais txiaj ntsig los ntawm nitriding rau saum npoo hnav thaum tuav cov tawv, cuam tshuam -cov tub ntxhais tiv taus. Tuag blocks tuav abrasive stainless hlau yuav tau txais ob qho tib si hardening thiab nitriding rau txheej tiv thaiv.

Cov ntsiab lus tseem ceeb ntawm cov neeg yuav khoom feem ntau saib dhau: qhov hloov pauv thaum lub sijhawm kho cua sov yog qhov tsis muaj kev zam. Steel nthuav, warps, thiab hloov raws li nws microstructure transforms. Cov neeg tsim khoom lag luam zoo suav rau qhov no los ntawm kev tawm hauv kev sib tsoo kom tiav thiab ntsuas cov khoom tom qab kev kho cua sov kom paub tseeb tias qhov kawg machining yuav coj txhua yam rov qab rau kev kam rau siab. Lub pob zeb hauv av tsuas yog 0.005 hli sab nraum qhov kev pom zoo yuav zoo li tsis tseem ceeb-tab sis nyob rau hauv qhov siab- ceev tuag, nws tuaj yeem ua kom cov npoo chipping thiab ua kom lub neej ntev heev.

Kev sim khiav thiab kev soj ntsuam zaum kawg

Kev sib dhos nqa tag nrho cov txheej txheem ntawm tus kheej thiab kho cov khoom ua ke rau hauv kev ua haujlwm tuag. Punches, tuag daim hlau, inserts, coj tus pins, springs, thiab strippers yog haum raws li cov duab kos. Ua tib zoo mloog mus rau kev xuas nrig ntaus-rau- tuag tshem tawm pov thawj, qhia kev sib dhos, thiab kev mus ncig stripper- cov txheej txheem siv tshuab uas txiav txim siab seb qhov tuag hauv kev tsim khoom puas ua tau raws li qhov xav tau lossis qhia txog teeb meem ntawm thawj zaug stroke.

Kev sim khiav yog qhov kev tshawb xav ntsib qhov tseeb. Siv cov khoom tsim tawm tiag tiag ntawm qhov npaj strip thickness, cov tuag yog mounted rau hauv xovxwm thiab ib tug luv luv strip yog pub los ntawm kev tsim cov qauv thawj zaug. Cov qauv no raug ntsuas tawm tsam qhov kos duab rau:

• Dimensional raug rau tag nrho cov yam ntxwv tseem ceeb
• Qhov chaw thiab qhov chaw nruab nrab - mus rau - nruab nrab nrug
• Khoov cov ces kaum thiab springback sib txawv
• Flatness hla ntawm qhov chaw
• Burr qhov siab ntawm tag nrho cov npoo sheared
• Cov tsos mob saum npoo- kuaj xyuas qhov khawb, cov cim tuag, los yog galling
• Cov khoom siv ruaj khov- tsis muaj qhov tawg, tawg, lossis dhau qhov thinning

Kev hloov kho nyob rau theem no yog xav tau, tsis muaj qhov tshwj xeeb. Springback tuaj yeem rub lub kaum sab xis me ntsis ntawm lub hom phiaj, yuav tsum tau them nyiaj hloov kho hauv qhov chaw tsim khoom. Kev txiav ntug tuaj yeem tsim cov burrs siab me ntsis, hu rau kev tshem tawm kom zoo -tuning. Kev sim-thiab- kho lub voj voog txuas ntxiv mus kom txog thaum cov qauv ua tau raws li txhua qhov kev xav tau kos duab thiab cov tuag ua haujlwm huv si- noj ruaj khov, tsis muaj khoom nqa, tsis muaj qhov tsis xws luag.

Kev tshuaj xyuas niaj hnub siv thev naus laus zis ua rau qhov kev lees paub no nruj dua li kev ntsuas phau ntawv puas tau.Coordinate Measuring Machine (CMMs)ntes cov ntaub ntawv seem hla ntau ntau ntawm cov yam ntxwv hauv ib qho kev teeb tsa, sib piv cov duab geometry tiag tiag tiv thaiv CAD nominal qhov tseem ceeb nrog micron - theem kev daws teeb meem.Optical thiab laser scanningsystems tsim tag nrho -surface 3D daim duab qhia chaw ntawm cov piv txwv, nthuav tawm qhov kev sib tw me me los yog qhov sib txawv ntawm qhov chaw uas qhov chaw kuaj xyuas nrog calipers yuav plam tag nrho.

Kev sib xyaw ua ke ntawm kev simulation- tsav tsim, precision machining, tswj kev kho cua sov, thiab kev sim ua kom pom tseeb yog qhov sib cais qhov tuag uas tsuas yog muaj los ntawm ib qho uas ua kom zoo ib yam, siab - qhov chaw zoo tshaj nws lub neej tag nrho. Txhua theem txhawb nqa lwm tus-thiab cov shortcuts ntawm txhua qhov chaw uas tsis muaj kev cuam tshuam los ntawm cov teeb meem zoo hauv qab.

Txawm li cas los xij, txawm tias ua tau zoo kawg nkaus tuag tsis muaj kev tiv thaiv rau cov rog uas nws ntsib thaum tsim khoom. Rov qab siab -kev cuam tshuam ceev, cov ntaub ntawv abrasive, thiab lub ntim ntawm cov strokes maj mam hnav txhua qhov txiav ntug thiab tsim nto. Qhov kev hnav ntawd, yog tias tsis muaj kev tswj hwm, ntsiag to erodes qhov zoo ntawm cov qauv kev tuag tau tsim kom ua tiav- yog vim li cas kev nkag siab ntau yam tsis xws luag stamping thiab lawv cov hauv paus ntsiab lus tseem ceeb npaum li kev nkag siab tias qhov tuag tau ua li cas.

Common Stamping Defects thiab yuav ua li cas tuag zoo tiv thaiv lawv

Ib tug tuag uas khiav zoo kawg nkaus ntawm mob stroke 10,000 tuaj yeem ntsiag to pib tsim kev tsis lees paub los ntawm mob stroke 100,000. Ntug tau rougher. Dimensions hloov. Cov khoom uas ib zaug dhau kev tshuaj xyuas pib ua lub tswb. Thaum muaj teeb meem tshwm sim ntawm qhov chaw stamped, qhov kev xav yog los liam cov xovxwm, cov khoom siv, lossis tus neeg teb xov tooj. Tab sis feem ntau tsis yog, lub hauv paus ua rau cov kab rov qab mus rau qhov nias tuag nws tus kheej- nws tsim, nws tus mob, los yog nws compatibility nrog cov xovxwm nws zaum nyob rau hauv.

Kev nkag siab txog kev sib txuas ntawm qee yam tsis xws luag thiab lawv cov tuag- keeb kwm muaj feem cuam tshuam rau cov kws tshaj lij kev kuaj mob uas ua rau kev daws teeb meem sai dua thiab, qhov tseem ceeb tshaj, tiv thaiv teeb meem ua ntej lawv pib. Ntawm no yog qhov ua tau zoo ntawm qhov feem ntau stamping tsis ua haujlwm thiab lawv qhia dab tsi txog kev tuag zoo.

Burring, Cracking, thiab Edge Defects

Burrs yog qhov pom tshaj plaws -thiab feem ntau yws txog - stamping defect. Txhua qhov kev ua haujlwm shearing ua rau qee qhov burr, tab sis thaum burr qhov siab nce siab tshaj qhov kev txwv, qhov teeb meem yuav luag txhua zaus taw qhia qhov tuag. Ob tug thawj culpris yog lub luag hauj lwm.

. Raws li kev tuag khiav, cov npoo ntse ntawm cov punches thiab tuag qhib maj mam npub. Uas dulling ua rau qhov chaw rollover ntawm ib feem ntawm ntug thiab tso cai rau cov khoom tsim kua muag ntau dua li shear kom huv si. Qhov tshwm sim: siab dua, ntau dua ragged burrs uas zuj zus zuj zus nrog txhua qhov mob stroke ntxiv. Yog tias qhov siab burr nce maj mam dhau ntawm kev tsim khoom, hnav cov cuab yeej yog qhov ua rau feem ntau.

Thib ob,punch tsis raug-rau- tuag tshem tawm. Raws listamping tsis ua hauj lwm tsom xam los ntawm Fabricatorpiav qhia, sib txawv xws li clearance interacting in the way that compound problems. Qhov kev tshem tawm tsawg dhau ua rau cov txheej txheem qis dua- ob npaug - txiav cov mob uas tawm ntawm qhov ntxhib, kub hnyiab thiab ua kom nrawm nrawm. Kev tshem tawm ntau dhau tso cai rau cov khoom rub thiab deform ua ntej tawg, tawm hauv qhov loj, tsis xwm yeem burrs thiab tapered slug profiles. Qhov xwm txheej twg ua rau lub neej luv luv thiab ua rau cov nqi seem.

Kev tawgthaum lub sij hawm tsim cov hauj lwm qhia ib zaj dab neeg sib txawv. Thaum cov ntawv hlau sib cais, nws tau ncab tshaj nws cov kev txwv. Hauv kev tuag- cov ntsiab lus hais txog, feem ntau txhais tau hais tias kev tsim cov radii nruj dhau rau cov khoom siv thiab cov thickness raug stamped, los yog qhov tuag geometry yuam cov khoom mus rau qhov tsis sib xws. Xav txog kev khoov ib daim ntawv hlau hla lub kaum ntse ntse piv rau qhov nkhaus maj mam- lub kaum ntse ntse ua rau muaj kev ntxhov siab thiab caw kom tawg. Lub qhov dej-engineered tuag siv radii loj txaus kom tsis txhob muaj kev ntxhov siab nyob rau hauv kev nyab xeeb txwv thaum tseem ua tiav lub hom phiaj geometry.

Tsim kom raug tuag thiab kev saib xyuas zoo ib yam tiv thaiv ob pawg ntawm ntug tsis xws luag. Kev tuav cov npoo ntse ntse los ntawm kev teem sijhawm regrinding ua kom burrs nyob rau hauv kam rau ua. Tsim cov chaw tsim khoom nrog cov radii uas tsim nyog thiab cov khoom siv tau siv tau raws txoj hauv kev- tau lees paub los ntawm CAE simulation- tiv thaiv kev tawg ua ntej qhov tuag puas tau mus txog hauv pem teb xovxwm.

Wrinkling, Springback, thiab Dimensional Drift

Tsis yog txhua qhov tsis xws luag cuam tshuam nrog cov khoom tsis ua haujlwm. Qee qhov teeb meem kev ntxhov siab tshaj plaws yog tshwm sim los ntawm cov khoom siv coj los ua raws nraim li lub cev kwv yees- tsis yog raws li qhov xav tau ntawm cov ntawv luam tawm.

Wrinklingtshwm sim thaum daim ntawv hlau buckles nyob rau hauv compressive kev nyuaj siab nyob rau hauv lub unsupported cheeb tsam thaum lub sij hawm kev kos duab los yog kev ua hauj lwm. Daim duab thawb ib daim ntawv hla ib lub rooj los ntawm ob sab - nws buckles upwards vim tsis muaj dab tsi tuav nws tiaj. Nyob rau hauv ib lub stamping tuag, lub qhov 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 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. Lub zog me me dhau lawm, thiab cov hlau nplaum ua ntej nkag mus rau hauv kab noj hniav. Raws li kev txheeb xyuas kev lag luam sau tseg, cov wrinkles tom qab ntawd tsim kev txwv tsis pub muaj peev xwm ua rau muaj kev sib cais thib ob - txhais tau tias ib qho tsis xws luag ua rau lwm tus.

Kev tuag- kev sib txuas zoo ntawm no yog ncaj qha: tus neeg siv khoom tsis muaj qhov tsim, qhov siab standoff, kos cov hlaws geometry, thiab qhov sib npaug sib npaug yog txhua qhov kev txiav txim siab tuag uas txiav txim siab seb qhov wrinkling yog tswj los yog tso cai rau tshaj tawm. Lub qhov dej zoo- tsim cov cuab yeej xovxwm thiab lub cev tuag sib npaug tuav lub zog kom meej- txaus los tiv thaiv wrinkling, tsis ntau heev uas nws txwv cov khoom ntws thiab ua kua muag.

Springback-qhov elastic rov qab ntawm cov hlau tom qab tsim- yog qhov kev sib tw tshaj plaws uas nyuaj rau kev tswj xyuas. Thaum lub punch khoov cov ntawv hlau mus rau 90 degrees thiab tom qab ntawd thim rov qab, qhov tsis nyob ntawm 90 degrees. Nws springs rov qab mus rau nws qhov qub tiaj tus, qee zaum los ntawm ob peb degrees. Rau cov hlau me me, cov nyhuv yog nruab nrab. Rau siab heev -lub zog steels (AHSS) thiab siab - lub zog aluminium alloys, springback tuaj yeem hnyav txaus los thawb cov khoom tawm ntawm kev ua siab ntev.

Tuag zoo nyob rau springback los ntawm kev them nyiaj: txhob txwm tshaj tawm - khoov ib feem kom tom qab elastic rov qab, nws tsaws ntawm lub hom phiaj. Raws li AutoForm Engineering cov kev tshawb fawb luam tawm nyob rau hauv Fabricator qhia tau hais tias, kev tswj xyuas lub caij nplooj ntoos hlav zoo ua raws li lub tswv yim zoo- ntsuas, txo, tswj, tom qab ntawd them nyiaj. Cov txheej txheem txo qis xws li npib thiab ironing txo qhov loj ntawm springback ua ntej kev them nyiaj txawm sim. Qhov kev pom tseem ceeb: cov nyiaj them rov qab tsuas yog ua haujlwm tau zoo thaum cov txheej txheem nws tus kheej rov ua dua, txhais tau tias tag nrho cov xwm txheej tuag, tonnages, thiab cov khoom tsis raug tswj kom nruj.

Dimensional driftyog subtler tab sis sib npaug kev puas tsuaj. Tshaj li kev tsim khoom ntev ntev, maj mam tuag hnav nthuav dav tshem tawm, hloov kho qhov chaw, thiab hloov qhov chaw tshwj xeeb los ntawm me me increments. Tus kheej qhov chaw tseem tuaj yeem dhau qhov kev tshuaj xyuas, tab sis txoj kab sib txawv txav mus tsis tu ncua mus rau qhov ciam teb ciam teb - thiab thaum kawg nws dhau los. Saib xyuas cov ntaub ntawv qhov ntev ntawm kev mob stroke ib txwm- suav cov ntu ntu, tsis yog tsuas yog tso siab rau thawj- kab lus thiab qhov kawg- cov ntawv txheeb xyuas, ntes nrawm nrawm txaus los teem sijhawm saib xyuas ua ntej tsis lees txais.

Nias -Die Compatibility thiab Nws Cov nyhuv ntawm Qhov Zoo

Ntawm no yog qhov tseem ceeb uas txawm tias muaj kev paub txog kev ua haujlwm stamping qee zaum saib tsis tau: qhov tuag zoo tshaj plaws hauv ntiaj teb yuav tsim cov khoom tsis raug yog tias nws khiav hauv xovxwm tsis raug. Cov xovxwm tuag zuj zus yuav tsum ua raws li qhov yuav tsum tau muaj nyob rau hauv ntau qhov tseem ceeb, thiab qhov tsis sib haum xeeb tsim teeb meem uas tsis muaj qhov hloov pauv tuag tuaj yeem kho tau.

Tonnageyog qhov txawv tshaj plaw. Txhua qhov kev ua haujlwm stamping yuav tsum muaj tus lej suav ntawm lub zog xovxwm, thiab cov xovxwm stamping zuj zus yuav tsum xa cov quab yuam ntawd nrog cov npoo kom seem. Undersized presses strain kom ua tiav cov hlab ntsha tawg, ua rau tsis sib haum thiab ua kom nrawm nrawm ntawm ob qho tib si tuag thiab xovxwm ncej. Cov xovxwm loj loj ua rau lub zog pov tseg tab sis feem ntau ua rau muaj kev pheej hmoo tsawg dua -tshwj tsis yog qhov ntau tshaj tonnage tsis raug txwv, uas tuaj yeem ua rau cov khoom puas tsuaj los ntawm ntau tshaj - mus ncig.

Xovxwm homtseem ceeb tshaj ntau tus neeg yuav khoom paub. Mechanical presses xa cov tonnage ncov ze rau hauv qab ntawm cov hlab ntsha tawg, ua rau lawv zoo tagnrho rau blanking thiab ntiav txoj kev. Hydraulic presses muab tag nrho tonnage thoob plaws hauv cov hlab ntsha, uas haum rau kev ua haujlwm sib sib zog nqus. Servo-tsav presses muaj programmable slide motion profiles-adjustable speed, inwell time, and force curves that can be tuned to match specific die requirements. Raws liAida America txoj kev tsom xam hauv MetalForming Magazinepiav qhia, servo presses tuav lub zog muaj nyob rau hauv qis speeds qhov twg mechanical presses poob nws sai, ua rau lawv tshwj xeeb tshaj yog muaj txiaj ntsig rau kev thov tsim cov ntawv thov uas yuav tsum tau ua kom qeeb, tswj cov lus tsa suab.

Lub txaj loj thiab kaw qhov siabyuav tsum ua raws li tus neeg tuag lub cev hneev taw. Kev nce qib tuag xovxwm nrog lub txaj tsis txaus ua rau tuag rau overhang, tsim kev txhawb nqa tsis sib xws thiab deflection hauv qab load. Tsis txaus kaw qhov siab tiv thaiv qhov tuag los ntawm kev kaw tag nrho, ua rau kev ua tsis tiav.

Ib tug tuag uas tsim qhov chaw flawless niaj hnub no yuav tsis ua li ntawd indefinitely yam tsis muaj kev cuam tshuam. Txhua tus mob stroke yuav siv lub microscopic tus xov tooj ntawm kev txiav cov npoo, tsim qhov chaw, thiab cov kab ke sib dhos. Kev tswj tus xov tooj ntawd- dhau ntawm cov txheej txheem kev saib xyuas uas khaws cov kev ua haujlwm tuag thoob plaws nws lub neej tsim khoom tag nrho- yog qhov txuas tseem ceeb tom ntej hauv cov saw zoo.

Tuag Cov Kev Pabcuam Saib Xyuas Uas Tiv Thaiv Koj Cov Peev Nyiaj Txiag

Lub stamping tuag tsis ua tiav ib zaug. Nws degrades ib stroke ib zaug -txhua qhov cuam tshuam dulling ib tug txiav ntug los ntawm microns, txhua lub voj voog hnav ib daim ntawv qhia bushing imperceptibly ze rau nws clearance txwv. Cov khoom tawm los ntawm cov xovxwm tseem tuaj yeem dhau los soj ntsuam niaj hnub no, tab sis tsis muaj cov txheej txheem kev saib xyuas, koj tab tom saib qhov zoo erode hauv qeeb qeeb. Thiab los ntawm lub sij hawm qhov tsis xws luag tau pom tseeb, qhov kev puas tsuaj rau koj qhov tuag-thiab koj cov nqi tsim khoom- twb tau ua tiav lawm.

Txawm li cas los xij, kev kho tuag tseem yog ib qho ntawm cov chaw tsis saib xyuas tshaj plaws hauv kev ua haujlwm stamping. Ntau lub khw kho nws raws li kev kho reactive: ib yam dab tsi so, ib tug neeg kho nws. Txoj kev ntawd raug nqi ntau dua li nws txuag. Kev tiv thaiv tiag tiag rau steel stamping tuag yog ib qho kev teem sijhawm, cov ntaub ntawv -tsav kev qhuab qhia uas khaws cia ib feem zoo, txuas lub neej tuag, thiab txo tus nqi tag nrho ntawm txhua qhov khoom tsim.

Kev Tiv Thaiv Kev Tiv Thaiv Cov Sijhawm thiab Kev Sib Tw

Kev tiv thaiv kev kho tsis zoo ib yam li kev kho tuag. Raws liArt Hedrick ntawm Dieology LLCpiav qhia, yog tias koj cov dej num niaj hnub cuam tshuam nrog kev kho cov ntaub qhwv tawg, vuam cov ntu puas, lossis khawb qhov seem ntawm qhov rub tuag, qhov ntawd yog kho- thiab feem ntau nws yog los ntawm kev tsim tsis zoo, teeb tsa tsis zoo, lossis kev saib xyuas tsis txaus. Kev saib xyuas kev tiv thaiv tiag tiag suav nrog kev ua kom ntse ntse, teem caij hloov cov khoom, thiab kev tshuaj xyuas kom zoo-txhua yam ua ntej teeb meem mus txog hauv pem teb xovxwm.

Ib qho kev saib xyuas ua tau zoo ua haujlwm nyob rau ntau lub sijhawm horizons:

• Txhua hnub lossis hloov pauv - qib kuaj:Ntxuav cov chips thiab cov khib nyiab los ntawm qhov tuag, xyuas cov ntsiab lus lubrication, paub meej tias cov khoom seem yog qhov tseeb, thiab pom qhov muag pom cov kab nrib pleb, xoob fasteners, lossis cov khoom uas ploj lawm. Cov kev soj ntsuam ceev no ntes tau cov teeb meem ntxov ua ntej lawv nce mus rau hauv qhov chaw nres tsheb.
• Kev tshuaj xyuas txhua lub lim tiam:Ntsuas qhov ntev ntawm qhov tseem ceeb xws li qhia kev tshem tawm thiab qhov chaw tus pin hnav. Xyuas cov phaj stripper, knockout functions, thiab springs. Sau txhua qhov drift kom cov ncauj lus pom thaum lub sijhawm.
• Lub caij nyoog-raws li kev pabcuam (ib zaug suav suav):Nyob ntawm cov khoom siv hardness thiab ntim ntau lawm, kev saib xyuas zoo dua feem ntau yog teem caij txhua txhua 100,000 txog 300,000 strokes. Cov dej num muaj xws li kev sib tsoo lossis hnav cov npoo txiav, txheeb xyuas qhov kev sib dhos tuag, xyuas cov phaj flatness, thiab sau cov roj nplua nyeem. Rau cov tuag khiav siab - cov ntaub ntawv hardness los yog kev khiav hauj lwm ntawm high speeds, ua kom lub cadence no.
• Kev kho mob tseem ceeb:Thaum ib tug tuag mus txog nws lub neej tsim-feem ntau pua pua txhiab mus rau tsheej lab ntawm hits-los yog tom qab rov regrinding mus txog qhov txwv hnav ntawm stamping tuag qhov chaw, teem ib tug tag nrho teardown thiab seem soj ntsuam. Qhov no yog qhov kev txiav txim siab rau kev tsim kho dua tshiab thiab hloov pauv.

Regrinding tsim nyog tau txais kev saib xyuas tshwj xeeb vim nws yog ib qho tseem ceeb tshaj plaws kev saib xyuas kev ua haujlwm. Txiav cov npoo ntawm cov punches thiab tuag qhov qhib tawg thaum lub sijhawm, ua kom cov burrs siab dua, noj cov teeb meem, thiab cov ntug tsis zoo ntawm cov khoom tiav. Regrinding restores cov npoo mus rau lawv qhov qub sharpness, zoo resetting tus tuag qhov kev ua tau zoo.

Tab sis regrinding tsis yog yooj yim li khiav ib tug nto grinder hla lub ntsej muag punch. Siv lub log sib tsoo tsis raug- ib qho uas thauj khoom ntau dua li tsis ua kom huv si - ua kom muaj cua sov ntau dhau uas tuaj yeem ua kom muag lossis tawg cov cuab yeej hardened. Dej nyab cov dej txias, kev xaiv lub log kom zoo sib xws rau cov cuab yeej steel qib, thiab kev sib tsoo lub kaum sab xis yog qhov tseem ceeb. Lub kaum sab xis yuav tsum yog hauv av kom txiav kev txiav txim siab nyob twj ywm, tiv thaiv kev hloov pauv ntau dhau ntawm cov khoom ua haujlwm thiab tuav cov xuas nrig ntaus - rau - kev sib dhos tuag. Cov yam ntxwv me me, tsis yooj yim yuav tsum yog hauv av kom lawv nkag mus rau cov khoom siv kawg, txo qhov cuam tshuam kev poob siab thiab kev pheej hmoo tawg.

Rau siab -Volume progressive tuag, ib co kev khiav hauj lwm txais ib tug tiv thaiv overhaul lub tswv yim ntawm kwv yees li 70-80% ntawm kev cia siab tuag lub neej es tsis yog tos rau kawg- ntawm- lub neej ntsuas. Txoj hauv kev no zam kev ua haujlwm nruab nrab tsis ua haujlwm uas cuam tshuam kev tsim khoom ntawm lub sijhawm phem tshaj plaws.

Qhov Kev Kho Mob cuam tshuam li cas rau qhov zoo thiab tus nqi ntawm cov tswv cuab

Kev sib txuas ntawm kev saib xyuas thiab ib feem zoo tsis yog qhov paub daws teeb meem - nws yog ntsuas tau ntawm cov xovxwm. Lub tshuab tshiab tshiab tsim cov khoom siv nrog cov chaw huv si, cov burrs tsawg, thiab qhov ntev. Raws li kev txiav cov npoo hnav ntawm lub voj voog kev saib xyuas, burr qhov siab nkag mus rau sab saud, ntug zoo degrades, thiab qhov sib txawv ntawm qhov loj tuaj. Cov khoom tseem tuaj yeem dhau los ntawm kev tshuaj xyuas ib ntus, tab sis cov npoo npog nrog txhua txhiab strokes.

Sab laug unchecked, qhov no maj mam degradation ua rau ib tug cascade ntawm theem nrab teeb meem. Siab burrs xav tau kev ua haujlwm deburring uas ntxiv cov nqi thiab lub sijhawm voj voog. Dimensional drift yuam cov neeg ua haujlwm kho cov xovxwm lossis shim tus tuag- kho sai uas npog qhov teeb meem tiag tiag. Deg defects los ntawm hnav ua ntu ua rau tsis lees paub ntau thiab cov neeg siv khoom tsis txaus siab. Thaum kawg, qhov kev puas tsuaj loj heev-ib pob tawg, tawg tawg, ib qho thaiv kab nrib pleb- kaw kev tsim khoom tag nrho thiab xav tau kev kho xwm txheej ceev ntawm tus nqi hwm.

Qhov no yog qhov twg tag nrho cov nqi ntawm kev xav tswv yim hloov pauv li cas koj ntsuas cov cuab yeej nqis peev. Xav txog ob qhov xwm txheej: tus nqi qis dua -tus nqi tuag ua los ntawm cov khoom siv nrog tsawg engineering, piv rau ntau dua - zoo hlau stamping tuag teeb ua los ntawm cov cuab yeej hwm zoo steels nrog kev kho cua sov zoo thiab qhov tseeb - cov khoom hauv av. Cov neeg tuag pheej yig dua tus nqi qis dua tab sis hnav sai dua, yuav tsum tau rov qab ntau zaus, tsim cov khoom seem ntau dua li nws degrades, thiab ncav cuag qhov kawg - ntawm - lub neej sai dua. Tus nqi tuag raug nqi ntau dua thaum pib tab sis ua haujlwm ntev dua ntawm kev saib xyuas lub sijhawm, tuav kev ua siab ntev dua, thiab tsim ntau qhov chaw ua ntej hloov.

Kev lag luam kwv yees qhia tias tus nqi tu txhua xyoo feem ntau khiav txog 5-10% ntawm tus nqi yuav khoom qub, thiab tuag yuav xav tau rov kho dua txhua 50,000 txog 200,000 strokes nyob ntawm cov khoom siv thiab qhov nyuaj. Qhov qis dua -zoo tuag uas xav tau rov ua dua ob zaug ntau zaus- lossis hloov xyoo ua ntej ntawm lub sijhawm teem sijhawm sai sai tshem nws cov nqi pib kom zoo dua.

Kev tuag zoo thiab kev saib xyuas yog qhov sib cais tsis tau hauv tag nrho cov kev lag luam tsim khoom. Lub qhov dej- ua tuag nrog kev qhuab qhia kev saib xyuas ua rau ntau qhov chaw, ntawm tus nqi qis dua - ib daim, nrog tsawg dua qhov tsis xws luag ntawm lwm qhov pheej yig dua uas hnav sai thiab xav tau kev cuam tshuam tas li.

Rau cov kws tshaj lij kev muag khoom, qhov no txhais tau tias qhov sib piv cuam tshuam tsis yog tus nqi tuag piv rau tus nqi tuag. Nws yog tus nqi tag nrho rau ib feem uas tau txais los ntawm tag nrho cov cuab yeej siv lub neej- suav nrog kev ua haujlwm txij nkawm, sib sau cov khoom siv, kev poob qis, seem, thiab lub sijhawm hloov pauv. Qhov kev suav ntawd yuav luag ib txwm nyiam qhov siab dua - cov cuab yeej zoo.
