Dab tsi yog Kev Txhim Kho Stamping Tuag thiab Vim Li Cas Lawv Tseem Ceeb

Xav txog ib qho cuab yeej uas xuas nrig ntaus, khoov, cov ntaub ntawv, thiab txiav ib feem ntawm cov hlau tiav hauv ib qho kev txuas mus tas li, ntau pua zaus hauv ib feeb. Qhov ntawd yog raws nraim li qhov kev nce qib stamping tuag ua. Rau cov kws tsim khoom tsim khoom thiab pab pawg muag khoom tau ua haujlwm nrog kev ntsuas cov zis thaum tuav nruj, kev nkag siab txog cov cuab yeej no los ntawm sab hauv tawm yog qhov sib txawv ntawm kev sib tw thiab raug nqi ntau dua - thiab - yuam kev.

Dab tsi yog Kev Txhaum Txhaum Kev Tuag

Ib qho kev nce qib stamping tuag yog cov cuab yeej precision ntsia rau hauv cov xovxwm stamping uas txav cov hlau sawb los ntawm cov chaw sib txuas ua ke, txhua qhov ua haujlwm tshwj xeeb los yog ua haujlwm rau ib qho xovxwm, kom txog rau thaum ib feem tiav yog sib cais ntawm qhov chaw nres tsheb kawg.

Yog lidab tsi yog ib tug progressive tuag nyob rau hauv lub tswv yim? Nws yog tus kheej - muaj cov txheej txheem tsim khoom. Lub coil ntawm cov ntawv hlau pub rau hauv cov xovxwm, thiab lub servo feeder nce lub sawb los ntawm qhov kev ncua deb, hu ua lub suab, nrog txhua qhov mob stroke. Ntawm txhua qhov chaw nres tsheb lub sawb ntsib kev ua haujlwm sib txawv: tho, khoov, npib, embossing, lossis trimming. Ib feem nyob twj ywm txuas rau ib qho khoom nqa nqa thoob plaws, tswj kev sib dhos kom txog thaum qhov kawg txiav tawm tawm. Ib tug stroke nyob rau hauv, ib tug tiav cov khoom tawm, tsis tu ncua.

Tej zaum koj yuav hnov ​​lub khw- pab pawg hauv pem teb hu nws tus neeg tuag. Txawm hais tias qhov luv luv, lub hauv paus ntsiab lus yog tib yam: ntau yam kev ua haujlwm sib sau ua ke rau hauv ib lub voj voog uas tsis siv neeg uas tshem tawm ib feem ntawm cov kauj ruam.

Vim li cas Progressive Dies Dominate Siab -Volume Production

Progressive stamping muab kev sib xyaw ua ke uas lwm txoj kev tawm tsam kom phim: nrawm, rov ua dua, thiab qis rau ib -tus nqi ntawm qhov ntsuas. Presses khiav nrawm tuag ua haujlwm nyob qhov twg los ntawm25 txog 200 strokes ib feeb, txhais tau hais tias ib feem tiav poob txhua feem ntawm ib ob. Vim hais tias txhua qhov chaw nres tsheb yog hauv av thiab hardened mus rau micrometer-theem precision, qhov sib npaug ntawm qhov sib npaug tuav hla ntau lab lub voj voog yam tsis muaj kev cuam tshuam los ntawm phau ntawv.

Rau cov pab pawg muag khoom ntsuas tus nqi, lej yog ncaj nraim. Tooling peev yog siab upfront, tab sis tus nqi marginal ntawm txhua qhov ntxiv shrinks rau me ntsis ntau tshaj li raw khoom thiab nias lub sij hawm. Ntawm cov ntim txhua xyoo saum toj no 50,000 units, cov neeg tuag niaj hnub raug txiav ib feem ntawm cov nqi ntawm 30 txog 80 feem pua ​​​​piv rau CNC fabrication txoj kev.

Cov kws tsim qauv sim ntau qhov sib txawv ntawm qhov sib txawv ntawm qhov zoo, kho qhov khoov lub kaum sab xis kom them nyiaj rau lub caij nplooj ntoo hlav lossis hloov kho qhov tob kom tsis txhob thinning dhau qhov kev txwv. Qhov tshwm sim yog qhov tsim qauv siv tau uas ncav cuag kev npaj ntau lawm sai dua nrog cov qauv ntawm lub cev tsawg dua.

Kev suav Tonnage yog lwm qhov chaw uas simulation them nyiaj faib. Txhua qhov chaw nres tsheb txiav thiab tsim cov rog yuav tsum suav nrog tsawg dua li cov xovxwm xaiv lub peev xwm, suav nrog qhov ua haujlwm siab tshaj qhov chaw tuag hauv qab qhov chaw kho tshuab kom zoo dua. Rau qhov chaw sib sib zog nqus, lub zog ua haujlwm, tsis yog qhov siab tshaj tonnage, dhau los ua qhov txwv. Simulation ntes cov kev txwv no thaum ntxov, kom ntseeg tau tias cov cuab yeej ua tau zoo sib xws ntawm cov xovxwm ua ntej kev cog lus.

Kev sib xyaw ua ke ntawm CAD / CAM parametric qauv, FEA tsim simulation, thiab cov kev tshawb fawb digital tau txo cov sijhawm txhim kho loj. Dab tsi ib zaug xav tau peb lossis plaub qhov kev sim ntawm lub cev feem ntau tuaj yeem daws tau hauv ib lub lis piam, txiav lub sijhawm ua haujlwm - mus rau - kev tsim khoom thiab tshem tawm cov nqi tuag hloov kho tom qab hardening.

Txawm li cas los xij, tus qauv simulation zoo tshaj plaws ua haujlwm ntawm cov khoom siv zoo tshaj plaws. Tiag -kev hloov pauv ntawm cov khoom siv hauv ntiaj teb, nias deflection, thiab lubrication tej yam kev mob qhia cov hloov pauv uas tsuas yog tshwm sim ntawm qhov nrawm nrawm, uas yog vim li cas xaiv cov khoom siv rau ob qho tib si workpiece thiab cov khoom siv tuag ua lub luag haujlwm txiav txim siab ntev - cov cuab yeej ua haujlwm tau ntev.

Cov ntaub ntawv nyob rau hauv Progressive Stamping thiab Tool Steel Xaiv

Cov qauv simulation khiav ntawm cov khoom siv zoo tshaj plaws, tab sis cov coils tuaj txog ntawm kab xovxwm muaj qhov tiag -world variation in hardness, elongation, and deg condition. Cov kev sib txawv no ripple los ntawm txhua yam ntawm kev tuag. Cov ntaub ntawv zoo tshaj plaws uas koj xaiv rau lub workpiece txiav txim seb muaj pes tsawg qhov chaw uas xav tau kev tuag, xovxwm ceev npaum li cas tuaj yeem mus txog, thiab ntev npaum li cas cov cuab yeej muaj sia nyob ua ntej kev kho.

Common Workpiece Materials thiab lawv cov yam ntxwv stamping

Progressive hlau stamping tuav ntau yam ntawm cov alloys, txhua tus coj sib txawv ntawm formability, lub zog, thiab abrasiveness. Cov khoom uas muaj qhov siab elongation khoov tau yooj yim tab sis tuaj yeem ua rau lub ntsej muag lub ntsej muag. Ib qho nyuaj alloy txiav huv si tab sis tsav mus txog tonnage xav tau thiab accelerates punch hnav. Sib piv cov workpiece rau daim ntawv thov thaum accounting rau tuag lub neej pauv-offs yog ib tug balancing ua rau txhua tus engineer ntsib.

Ntawm no yog yuav ua li cas cov ntaub ntawv zoo tshaj plaws stamping sib piv:

Cov pa roj carbon steel nce qib stamping tseem ua haujlwm rau tus nqi -sensitive, siab - ntim qhov chaw. Txias-rolled carbon steel muaj ib tug du nto, zoo formability, thiab tsawg raw khoom tus nqi, ua rau nws lub neej ntawd xaiv rau brackets, clips, thiab structural Cheebtsam. Stainless hlau nce qib stamping xav tau ntau dua los ntawm qhov tuag: ntau dua tonnage, nruj dua lubrication tswj, thiab cov cuab yeej hlau ntsuas rau cov nplaum- hnav tsis kam. Cov neeg tsim khoom tuag feem ntau ntxiv cov chaw nres tsheb tsis muaj zog thaum tsim cov qib stainless kom faib cov quab yuam thiab txo cov kev ntxhov siab hauv cov sawb.
