Plaub yam tseem ceeb tshaj plaws: tensile zog, hardness, ductility, thiab thickness. Txhua tus hloov pauv li cas cov ntawv hlau tuag yuav tsum tau tsim los tsim cov khoom siv tau.

Hlau thiab Stainless Hlau Stamping Consideration

Hlau tseem yog cov khoom siv ntau tshaj plaws rau cov khoom siv stamped, tab sis "steel" npog ntau yam kev coj cwj pwm. Cov hlau me me (feem ntau nyob rau hauv 350 MPa tensile lub zog) yog zam txim rau - nws txiav kom huv si, cov ntaub ntawv tsis muaj caij nplooj ntoos hlav ntau dhau, thiab ua rau muaj kev hnav tsis zoo. Stainless hlau yog ib yam tsiaj txawv kiag li.

Cov qib stainless xws li 304 thiab 316 muaj tensile zog tshaj 500 MPa, ua hauj lwm - harden ceev thaum lub sij hawm tsim, thiab ua kom muaj cua sov ntau ntawm cov punch- mus rau - cov ntaub ntawv interface. Rau cov hlau stamping tuag ua cov alloys nyuaj, koj yuav pom ntau qhov kev hloov kho engineering ua qhov yuav tsum tau ua:

• Tighter clearances- Cov ntaub ntawv nyuaj duance clearance feem puatxhawm rau tiv thaiv kev tawg ntxov ntxov thiab txiav quab yuam ntau dhau. Stainless feem ntau xav tau 10-15% ntawm cov khoom tuab ntawm ib sab, piv rau 6-10% rau cov hlau me me.
• Siab tsim rog- Xovxwm tonnage xav tau dhia 50-60% thaum tsiv los ntawm cov hlau me me mus rau stainless. Undersized presses ua rau kev ua tsis tiav, npib cov cim, thiab nrawm hnav hla txhua yam khoom siv.
• Springback them nyiaj- Cov hlau tsis muaj zog ntau dua - mus rau - tensile ratio txhais tau tias elastic rov qab ntau dua tom qab khoov. Die designers must over-bend by 2-4 degrees (sometimes more) to hit target angles, and forming punches may need modified radii to account for the kickback.
• Accelerated tuag hnav- Qhov xwm txheej ntawm stainless xav tau hwm stamping tuag steel rau punch thiab tuag thaiv kev tsim kho. D2 lossis M2 cov cuab yeej steel, feem ntau nrog TiN lossis AlCrN txheej, ua qhov tsim nyog los tswj cov ntug ntse los ntawm kev ua haujlwm ntev dua.

Qhov tshwm sim? Hlau stamping tuag ua rau cov nqi tsis muaj nqi ntau dua vim tias lawv xav tau cov ntaub ntawv zoo dua, kev tsim khoom nruj dua, thiab cov xovxwm muaj zog dua. Tab sis qhov kev nqis peev ntawd them tawm hauv qhov zoo ib yam thiab ncua sij hawm ntev ntawm regrinds.

Aluminium thiab Copper Alloy Cwj Pwm hauv Tuag

Aluminium coj cov txheej txheem sib txawv kiag li rau cov txheej txheem stamping. Nws yog kwv yees li ib -peb qhov ntom ntawm cov hlau thiab cov mos mos- uas zoo li nws yuav tsum yooj yim rau stamp. Hauv kev xyaum, qhov softness tsim teeb meem steel yeej tsis ua.

Qhov teeb meem loj tshaj plaws nrog aluminium stamping tuag yog galling. Aluminium yog ib qho "nco" hlau uas nyiam txias -weld microscopic hais mus rau qhov chaw tuag thaum lub sij hawm siab - kev sib cuag. Thaum pib pib, nws snowballs: txhua qhov mob stroke tom qab khaws cov khoom siv ntau dua, khawb qhov txuas ntxiv, thiab nws thiaj li ua rau cov neeg tuag ntau tshaj qhov yooj yim polishing. Kev tiv thaiv galling yuav tsum muaj ntau- txheej txheej zoo:

• Tuag coatings- PVD txheej zoo li Titanium Nitride (TiN) los yog Pob Zeb Diamond-Zoo li Carbon (DLC) tsim ib qho tsis muaj -stick barrier ntawm txhuas thiab cov cuab yeej steel nto.
• Nto tiav- Daim iav- polishing forming deg txo kev sib txhuam-tsim cua sov, uas yog thawj qhov ua rau cov nplaum hnav.
• Cov cuab yeej steel xaiv- High-vanadium steels (xws li CPM 10V) muaj kev tiv thaiv zoo tshaj rau cov nplaum hnav ua rau txhuas.
• Tshwj xeeb lubrication- Chlorine- cov kua hluavtaws pub dawb muab ciam teb lubrication yam tsis muaj staining lub txhuas nto.

Aluminium kuj tseem qhia tau hais tias lub caij nplooj ntoos hlav rov qab-ntau tshaj steel-vim nws cov qauv ntawm elasticity yog kwv yees li ib -peb ntawm cov hlau (kwv yees li 10,000 ksi piv rau 30,000 ksi). Khoov uas yuav tuav lub kaum sab xis nyob rau hauv cov hlau yuav rov qab zoo nyob rau hauv txhuas, yuav tsum tau tshaj - dabtsi yog khoov los yog kev ntxhov siab - nyem nta ua rau tuag.

Tooj liab thiab tooj dag alloys zaum ntawm lwm qhov kawg ntawm qhov softness spectrum. Lawv tsim tau yooj yim nrog tsawg kawg nkaus springback, tab sis lawv cov softness txhais tau hais tias lawv nyob rau saum npoo ntawm qhov chaw ntawm qhov chaw tuag. tooj liab stamping feem ntau yuav tsum tau polished tooling thiab ceev stripper siab teeb tsa kom tsis txhob muaj kev puas tsuaj rau cov tshuaj pleev ib ce. Nyob rau sab saum toj, tooj liab alloys ua rau tuag tsawg heev, yog li kev siv lub neej zoo heev txawm tias cov cuab yeej txheem steels.

Tsis hais txog ntawm cov alloy, Tshuag thickness yog ib qho kev hloov pauv loj tshaj plaws hauv kev suav daws. Kev lag luam- qauv qauv yog ncaj nraim:

Txiav Clearance (ib sab)=Khoom Thickness x Clearance Coefficient

Covclearance coefficient feem ntau yog li ntawm 5% mus rau 10%ntawm cov ntaub ntawv thickness, nyob ntawm seb lub alloy lub hardness thiab qhov xav tau ntug zoo. Cov ntawv thov kev txiav txim siab siv qhov qis kawg (ib puag ncig 5%) rau qhov tsawg kawg nkaus burr thiab du shear nto. General stamping siv 8-10% kom ntev lub neej tuag thiab txo kev txiav quab yuam.

Piv txwv li, stamping 1.0 hli me me hlau nrog 8% coefficient muab rau koj 0.08 hli clearance ib sab. Hloov mus rau 2.0 hli stainless hlau ntawm 12% thiab koj tab tom saib ntawm 0.24 hli ib sab -ib qho kev nce peb zaug uas xav tau qhov sib txawv ntawm qhov sib txawv ntawm qhov ntev thiab xuas nrig ntaus.

Thickness tseem ua rau cov kev txiav txim siab muaj feem xyuam:

• Punch zog- Cov ntaub ntawv tuab dua yuav tsum tau txiav quab yuam ntau dua, uas txhais tau hais tias qhov loj dua cov hlaws loj dua - ntu kom tsis txhob buckling.
• Lub zog stripper- Thicker Tshuag tuav lub punch ntau nruj, thov kom muaj zog springs los yog nitrogen cylinders kom strip cov khoom ntseeg tau.
• Yam tsawg kawg nkaus feature- Txoj cai dav dav yog tias qhov tsawg tshaj plaws txoj kab uas hla yuav tsum tsis txhob tsawg tshaj li cov khoom thickness. Punch dab tsi me me thiab koj pheej hmoo lub cuab yeej tawg.
• Tsim radii- Yam tsawg kawg khoov vojvoog nplai nrog tuab. Hlau feem ntau tso cai rau lub vojvoog khoov sib npaug li 1T (ib zaug tuab), thaum txhuas feem ntau xav tau 2T lossis 3T kom tsis txhob tawg.

Cov khoom sib piv rau Stamped Parts

Kev xaiv cov ntaub ntawv tsis yog tsuas yog txiav txim siab dab tsi mus rau ntawm lub kauj - nws ripples los ntawm txhua qhov kev txiav txim siab los ntawm punch hardness mus nias tonnage mus rau lub sijhawm tu. Tau txais cov kev txwv no nyob rau theem tsim tiv thaiv cov teeb meem qis qis uas noj rau hauv kev tsim khoom zoo: burrs uas loj hlob sai heev, khoov uas yuav tsis tuav lub kaum sab xis, thiab qhov chaw uas cim los yog gall nyob rau hauv thawj txhiab strokes.

Cov teeb meem nram qab no tsim nyog lawv tus kheej kuaj. Txawm tias muaj cov ntaub ntawv zoo sib xws thiab kev tshem tawm, cov teeb meem tshwj xeeb tuaj yeem tshwm sim hauv kev tsim khoom-thiab txhua tus taug qab rov qab mus rau lub hauv paus tswj tau hauv qhov tuag.

Tej yam tsis xws luag hauv Tuag Stamped Parts thiab Yuav Tiv Thaiv Lawv Li Cas

Txawm tias ib tug zoo kawg nkaus engineered tuag nws thiaj li ua ib feem. Qhov sib txawv ntawm lub qhov dej -khiav stamping kev khiav hauj lwm thiab ib qho khoom seem- hnyav los ntawm kev nkag siab tias vim li cas qhov teeb meem tshwm sim thiab daws cov hauv paus hauv paus ua ntej lawv nce ntxiv. Burrs, springback, wrinkles, kab nrib pleb, thiab thinning yog tsib qhov tsis xws luag uas suav rau feem ntau ntawm qhov tsis lees paub tuag stamped qhov chaw. Txhua tus taug qab ncaj qha rov qab mus rau ib qho cuab yeej tshwj xeeb lossis cov txheej txheem uas tuaj yeem tswj tau.

Burr Tsim thiab Txiav Clearance Control

Burrs tau tsa, cov npoo ntse uas tsim raws li qhov kev txiav tawm ntawm qhov chaw stamped tom qab xuas nrig ntaus, blanking, los yog trimming. Lawv yog cov kev tsis txaus siab tshaj plaws nyob rau hauv stamped ib feem ntau lawm, thiab yuav luag ib txwm taw tes rau ib tug clearance teeb meem ntawm cov hlau punches thiab tuag thaiv.

Nov yog qhov tshwm sim hauv qhov tuag thaum lub sij hawm txiav cov hlab ntsha: cov punch txuas nrog daim ntawv, thawb nws dhau los ntawm nws lub zog shear, thiab cov khoom tawg ntawm ib txoj kab txuas lub punch ntug mus rau qhov tuag thaiv ntug. Thaum kev tshem tawm tau zoo, cov kab tawg ua tau zoo sib xws, ua rau thaj chaw zoo nkauj nrog cov rollover tsawg thiab nruj, ze li qhov pom tsis pom. Thaum clearance yog nruj heev, txiav quab yuam spikes thiab cov ntaub ntawv kua muag es shearing. Thaum clearance loj heev, cov hlau yob mus rau hauv qhov sib txawv ua ntej fracturing, tawm hauv ib tug ragged ntug thiab oversized burr.

Cov lus qhia kev lag luam rau cov hlau me me yog 5-8% ntawm cov khoom tuab ntawm ib sab. Stainless hlau thiab siab zog alloys thawb uas nce mus txog 10-15%. Tau txais tus lej no nyob rau theem tsim yog qhov tseem ceeb, tab sis nws tsuas yog ib nrab ntawm kev sib ntaus sib tua.

Tuag hnav qhia txog qhov sib txawv thib ob. Raws li stamping tuag punches thiab tuag blocks voj voog los ntawm kev tsim khoom, lawv cov npoo txiav maj mam dhau mus. Qhov kev vam meej dulling no ua rau muaj txiaj ntsig zoo ntxiv rau kev ua haujlwm tshem tawm dhau ntawm nws tus nqi tsim, thiab burr qhov siab nce ntxiv nrog txhua txhiab strokes. Kev soj ntsuam burr qhov siab thaum lub sij hawm tsim khoom muab lub teeb liab ceeb toom rau thaum regrinding lossis punch hloov yog xav tau. Ib feem uas ntsuas 0.05 mm burr ntawm kev teeb tsa yuav nkag mus rau 0.15 mm los ntawm 200,000th hit-zoo dhau qhov kev txwv rau ntau daim ntawv thov.

Springback, Wrinkling, thiab Cracking Tiv Thaiv

Kev tsim cov teeb meem tsis yooj yim dua li txiav qhov tsis xws luag vim tias lawv koom nrog cov khoom siv tus cwj pwm nyob rau hauv kev ntxhov siab es tsis yog qhov yooj yim clearance ntsuas.

Springbackyog qhov elastic rov qab ntawm cov hlau tom qab khoov quab yuam tawm. Ib nrab rov qab mus rau nws qhov qub tiaj tus, ua rau koj nrog lub kaum sab xis uas yog ob peb degrees tawm ntawm lub hom phiaj. High- cov ntaub ntawv muaj zog nthuav tawm ntau qhov rov qab vim tias lawv khaws lub zog elastic zog dua. Cov kev daws teeb meem suav nrogcompensating lub kaum sab xis tuag thaum tsim(tshaj -khoov los ntawm qhov xav tau ntawm lub caij nplooj ntoo hlav), siv cov hauv qab los yog npib nyiaj strokes uas plastically deform lub khoov apex, thiab ntxiv stiffening tav nyob ze ntawm txoj kab khoov kom xauv lub geometry.

Wrinklingzoo li yoj-zoo li cov buckles ntawm flange lossis phab ntsa ntawm cov khoom kos. Nws tshwm sim thaum compressive kev nyuaj siab tshaj ntawm daim ntawv tsis kam mus buckling - feem ntau vim hais tias lub blanker quab yuam yog tsawg dhau los yog kos cov hlaws dai tsis txwv cov khoom ntws zoo. Ua kom lub siab tsis muaj zog, ua kom zoo dua cov hlaws geometry, thiab kho lubrication faib feem ntau daws qhov teeb meem.

Kev tawgtshwm sim thaum tensile strain tshaj cov khoom ductility txwv. Koj yuav pom nws ntawm qhov nkhaus nkhaus, sib sib zog nqus- kos cov ces kaum, thiab thaj chaw uas cov khoom thins ntau dhau. Cov hauv paus ntsiab lus feem ntau suav nrog - me me punch radii, aggressive single-stage drawing, and poor grain direction alignment. Cov tswv yim tiv thaiv tsom mus rau kev nthuav tawm cov kab mob: loj dua radii, multi-theem forming, intermediate annealing rau sib sib zog nqus draws, thiab aligning tseem ceeb khoov nyob rau hauv lub grain kev taw qhia es tsis mus rau tib seem.

dabtsi yog khoov yog qhov kev ua haujlwm ntau tshaj plaws hauv stamping. Nws deforms daim ntawv raws ib tug ncaj axis, tsim nta xws li tabs, raws, brackets, thiab mounting flanges. Suab yooj yim-tab sis ua tiav lub kaum sab xis khoov kom raug tsis tu ncua thoob plaws kev tsim khoom yog ib qho nyuaj dua hauv kev tsim khoom lag luam.

Peb lub hauv paus bending txoj kev tshwm sim hauv stamping tuag:

• V-khoov- Lub punch yuam cov ntawv rau hauv V- kab noj hniav nyob rau hauv qhov tuag thaiv. Lub kaum sab kawg nyob ntawm seb qhov punch tob npaum li cas. Huab cua dabtsi yog khoov (qhov twg cov punch tsis hauv qab) muab qhov yooj yim vim tias cov ces kaum sib txawv tuaj yeem ua tiav nrog tib lub cuab yeej. Hauv qab (qhov twg lub punch tag nrho lub rooj) muab lub kaum ntse ntse tswj tab sis xauv koj rau hauv ib qho duab geometry.
• U-khoov- Lub punch tsav cov ntawv rau hauv U- zoo li tus channel, ua ob qho tib si khoov rau hauv ib leeg. Lub siab ncoo hauv qab lub punch tuav cov ntawv tiaj tus thaum tsim, tiv thaiv hauv qab los ntawm kev hneev. Txoj kev no tsim cov tshooj channel thiab C-zoo li tus profiles zoo.
• So khoov- Ib tug ntug ntawm daim ntawv yog clamped thaum ib tug punch so qhov dawb seem tshaj ib lub vojvoog. Txoj hauv kev no ua haujlwm zoo hauv kev vam meej tuag vim nws tsis tas yuav tsum tau daim ntawv txav mus rau tus neeg nqa khoom. Nws yog qhov mus- mus rau txoj hauv kev tsim flanges thiab tabs ntawm qhov chaw uas tseem txuas nrog lub sawb thaum ua.

Tsis hais txog ntawm txoj kev, txhua qhov khoov qhia ob qho tib sicompression ntawm sab hauv vojvoog thiab nro ntawm lub vojvoog sab nraud.
