Ntau lawm khiav tuag feem ntau cov pa roj carbon steel (0.005 "mus rau 0.250" tuab), stainless hlau, txhuas, tooj liab alloys, thiab tooj dag. Cov ntaub ntawv hnyav dua thiab tuab dua xav tau cov hlau hnyav dua, kev tshem tawm loj dua, thiab kev tu ncua ntau zaus. Stainless hlau thiab siab - zog alloys, piv txwv li, feem ntau yuav tsum tau carbide inserts ntawm tej chaw nres tsheb los tiv thaiv abrasive hnav uas yuav sai sai degrade cov pa twj steels ntawm ntau lawm.

Cov ntim no- cov kev qhia tshwj xeeb uas tau tsav los txhais tsis yog li cas cov neeg tuag ua haujlwm rau hnub ib, tab sis yuav ua li cas nws tuav tau thoob plaws nws lub neej ua haujlwm tag nrho. Cov lus nug txog kev ruaj ntseg ntawd coj ncaj qha mus rau cov kev xaiv ntawm cov qauv - hardened kev tsim kho, ntxig tsim, thiab cov khoom siv engineering - uas cais cov khoom tsim tawm los ntawm luv luv - cov cuab yeej ua qauv.

Tuag siv txoj kev rau ntau lawm khiav mus ntev

Ib tug tuag uas khiav rau ib lub lim tiam thiab ib tug tuag uas khiav rau peb lub xyoos yuav zoo ib yam li sab nraum. Qhov sib txawv nyob rau hauv kev txiav txim siab ntawm kev tsim kho faus rau hauv - qib steel hauv txhua qhov punch, txawm tias txiav cov ntsiab lus yog qhov ruaj khov lossis ntxig rau-style, thiab yuav ua li cas txhua yam tiv thaiv kev qaug zog ntawm ntau lab ntawm cov xovxwm. Cov txheej txheem kev xaiv no yog dab tsi cais steel stamping tuag ua rau kev tsim khoom ntev los ntawm cov cuab yeej tsim kom tau los ntawm kev siv sijhawm luv luv.

Hardened Tool Steel thiab Carbide Insert Tsim

Kev xaiv cov khoom siv hauv kev tsim khoom tuag tsis yog ib qho kev txiav txim siab. Nws yog qhov chaw nres tsheb -los ntawm- chaw nres tsheb kev txiav txim siab engineering uas sib tw txhua qhov nthuav dav qhov kev ntxhov siab ib puag ncig rau txoj cai stamping tuag steel.

Cov kev xaiv feem ntau tawg zoo li no:

• D2 (High -carbon, siab -chromium)- Kev lag luam benchmark rau blanking thiab tho chaw nres tsheb. D2 muab qhov tshwj xeeb hnav tsis kam ntawm HRC 60-62, ua rau nws lub neej ua haujlwm rau kev txiav cov pa roj carbon steel thiab softer alloys. Nws tsis muaj zog yog brittleness - ntxhib carbides ua raws li kev ntxhov siab concentrators nyob rau hauv qhov hnyav.
• A2 (Air-tuaj khov)- Muab qhov sib npaug profile nrog tsawg hnav tsis kam tshaj D2 tab sis tseem ceeb dua toughness. A2 kuj tau dhau los ntawm kwv yees li 40% tsawg dua qhov hloov pauv thaum kho cua sov dua li cov roj- cov hlau tawv tawv, ua rau nws zoo tagnrho rau cov ncauj lus kom ntxaws punch geometries qhov twg tom qab- cua sov- kho qhov tseeb qhov teeb meem.
• M2 (High -Steel ceev)- Siv nyob rau hauv chaw nres tsheb uas muaj kev sib txhuam cua sov los ntawm qhov siab -kev ua haujlwm ceev yuav ua rau cov pa txias txias- ua haujlwm steels. M2 khaws nws cov tawv tawv ntawm qhov kub siab, ua rau nws haum rau kev tuag khiav ntawm 600+ strokes ib feeb.
• DC53 (Txhim kho txias- ua haujlwm hlau)- Kev hloov pauv niaj hnub no ntawm D2 uas nce mus txog 62-64 HRC thaum xa tawm kwv yees li ob npaug ntawm qhov tawv ntawm D2. DC53's high-temperature tempering compatibility kuj ua rau nws zoo heev substrate rau PVD txheej zoo li TiN los yog DLC.
• Carbide inserts- Tshwj xeeb rau siab tshaj -cov chaw hnav khaub ncaws lossis thaum ua cov khoom siv abrasive xws li stainless hlau thiab siab - lub zog alloys. Carbide xa cov hardness siab tshaj 90 HRA thiab tuaj yeem ua rau cov cuab yeej siv tau los ntawm 5 mus rau 10 zaug, txawm tias nws yuav tsum tau ua tib zoo saib xyuas kom tsis txhob tawg hauv qhov cuam tshuam.

Kev xaiv cov logic yog ncaj nraim: phim cov qib stamping tuag steel rau cov khoom siv ua haujlwm abrasiveness, qhov chaw nres tsheb hom kev ntxhov siab (hnav thiab cuam tshuam), thiab qhov xav tau ntaus suav ua ntej kev saib xyuas. Ib qho kev xuas nrig ntaus txiav 0.040" stainless ntawm 400 strokes ib feeb ntsib qhov sib txawv ntawm ib puag ncig zoo li qhov chaw nres tsheb dabtsi yog khoov 0.020" tooj liab - thiab cov hlau tuag ntawm txhua qhov chaw nres tsheb yuav tsum muaj kev cuam tshuam qhov sib txawv.

Ntxig-Style vs. Solid Die Construction

Ntawm no yog qhov uas ntau lawm xav diverges sharply los ntawm prototype logic. Cov khoom tuag - qhov twg cov punch lossis tuag nthuav dav yog machined ncaj qha los ntawm ib qho thaiv - muab qhov zoo tshaj plaws rigidity thiab raug. Rau kev khiav luv luv, qhov kev simplicity ua haujlwm zoo. Tab sis thaum txiav ntug dulls ntawm ntaus 80,000 nyob rau hauv ib lab-txoj kev pab cuam, koj tsis xav rub tag nrho cov seem tuag rau regrinding.

Ntxig-style kev tsim kho daws qhov no los ntawm kev sib cais cov khoom siv los ntawm lub cev tuag. Cov punch los yog txiav cov ntsiab lus yog ib qho hloov pauv tau nias los yog bolted rau hauv ib lub hnab ntim khoom los yog lub hnab tshos, tso cai rau nws hloov pauv yam tsis muaj kev cuam tshuam tag nrho ntawm cov khoom sib dhos.

Cov khoom zoo yog qhov tseem ceeb:

• Kev kho sai dua- Ib lub tsho hnav tuaj yeem hloov tau lossis rov ua dua thiab rov nruab dua hauv feeb ntau dua li teev. Cov tuag nyob ntawm cov xovxwm ntev dua.
• Tus nqi rov qab qis dua- Koj sharpen ib me me ntxig es tsis yog ib tug loj monolithic thaiv, txo cov khoom tshem tawm thiab lub sij hawm tshuab.
• Txo downtime- Cov khoom seem khaws cia hauv cov khoom muag txhais tau tias xoom lub sijhawm tos rau kev sib sau. Sib pauv, rov pib dua, thiab ua kom lub ntsej muag hnav offline.
• Khoom siv optimization- Cov carbide kim lossis PM steel tsuas yog mus rau qhov hnav xav tau nws. Cov khoom txhawb nqa tuaj yeem yog cov tawv tawv, tsis tshua muaj nqi hlau uas tiv thaiv kev poob siab yam tsis xav tau qhov hnyav hnyav.

Cov khoom tuag tseem muaj lub luag haujlwm hauv kev tsim khoom thaum rigidity yog qhov tseem ceeb - cov chaw tsim khoom hnyav lossis kev ua haujlwm loj blanking qhov twg ntxig interfaces tuaj yeem qhia deflection. Tab sis rau kev tho, trimming, thiab nthuav dav txiav hla ntau- chaw nres tsheb nce qib tuag, ntxig kev tsim kho yog tus qauv tsim vim nws ncaj qha txo tus nqi- ib- ntaus dhau lub cuab yeej lub neej.

Tseem ceeb Stamping Tuag Cheebtsam Uas Pab Tau Ntau Lawm Ntev

Lub tshuab tuag yog ib qho system, tsis yog ib qho cuab yeej. Txhua feem ua lub luag haujlwm hauv kev tswj xyuas qhov tseeb hla ntau lab lub voj voog. Thaum ib lub ntsiab tsis ua hauj lwm los yog drifts, ib feem zoo raug kev txom nyem tam sim ntawd. Ntawm no yog cov tseem ceeb stamping tuag Cheebtsam thiab dab tsi lawv pab:
