1.Dab tsi yog ob lub ntsiab lus ntawm lifespan?
Sharpening lub neej (sib tsoo lub sij hawm): Tus naj npawb ntawm stamping cycles ib tug tuag tuaj yeem tiv taus los ntawm nws thawj zaug sharpening mus txog rau thaum txiav ntug hnav mus rau qhov chaw uas qhov dawb paug tshaj kam rau ua (feem ntau, burr qhov siab tshaj 10-15% ntawm cov khoom thickness) thiab yuav tsum tau re-sharpening.
Tag nrho lub neej (scumulative stampings): Tag nrho cov naj npawb ntawm cov khoom tsim los ntawm ib leeg tuag los ntawm kev siv thawj zaug kom txog rau thaum nws raug muab pov tseg vim qhov sib txawv ntawm qhov sib txawv, tawg, lossis qaug zog tsis ua haujlwm tom qab ntau qhov kev sib tw.
2.Dab tsi yog qhov kev pab cuam lub neej ntawm xuas nrig ntaus zoo tib yam qis- carbon steel txias- dov coils?
Khoom thickness: 1.0mm ~ 3.0mm
Khoom siv: DC01, DC04, SPCC, Q235
Cov khoom siv tuag: High- zoo Cr12MoV, DC53 (hardness HRC 58-62)
Lub neej ntse: Kwv yees li 50,000 ~ 150,000 cycles (nyob ntawm lubrication thiab clearance uniformity)
Tag nrho lub neej: Kwv yees li 1 lab ~ 3 lab lub voj voog
Faj seeb: Feem ntau, ib qho re-ntxhiab tuaj yeem rov qab los zoo li tshiab kom txog rau thaum qhov kev tuag txiav ntug qhov ntev tsis kam lees lossis qaug zog tshwm sim.
3.Qhov kev pab cuam lub neej ntawm stamping siab -lub zog steel lossis precision stamping steel yog dab tsi?
Thickness Range: 3.0mm ~ 6.0mm (los yog tuab dua)
Khoom siv: 65Mn, 50Mn, S50C (zoo stamping hlau), Q460, thiab lwm yam siab - lub zog steels
Cov khoom siv tuag: High-toughness hmoov siab- steel ceev (xws li ASP23, ASP60) lossis cemented carbide
Cov yam ntxwv: Kev hnav ntawm cov tuag tshwm sim los ntawm cov ntaub ntawv no nce exponentially. Tshwj xeeb tshaj yog lub caij nplooj ntoos hlav steels xws li 65Mn, uas tsis tsuas yog muaj lub zog siab, tab sis kuj muaj qee qhov kev toughness, uas ua rau muaj kev cuam tshuam loj rau tuag.
Ntsej Muag Lub Neej: Kwv yees li 20,000 ~ 50,000 lub voj voog (cov hlau zoo tib yam yuav tsum tau rov ua dua-nplaum tom qab 10,000-20,000 cycles)
Tag Nrho Lub Neej: Kwv yees li 300,000 ~ 1,000,000 cycles
4.Dab tsi yog yam tseem ceeb uas cuam tshuam rau lub neej?
Tuag Clearance
Tseem ceeb: Yog hais tias qhov blanking clearance tsawg dhau, hnav nce ntau heev; Yog hais tias qhov clearance loj dhau, tus ntoo khaub lig-sectional tsis zoo, thiab theem nrab shearing yog yooj yim generated, accelerating chipping.
Lub Xeev Zoo: Rau cov khaub thuas- dov coils, nws raug nquahu kom siv 5% ~ 10% ntawm cov khoom tuab raws li ib qho - sab clearance (tus nqi tshwj xeeb yog nyob ntawm cov khoom hardness).
Lubrication tej yam kev mob
Kev sib tsoo qhuav (tsis muaj lubrication) vs. ntub sib tsoo (nrog lubrication) tuaj yeem ua rau muaj qhov sib txawv ntawm 3 ~ 5 npaug ntawm lub neej. Tshwj xeeb tshaj yog rau kev kos duab thiab tuab phaj blanking, lubricating roj yuav dissipate tshav kub thiab tiv thaiv hlau buildup.
Tuag Thaum tshav kub kub kho thiab kho deg
Kev kho cua sov li qub: HRC 58-60, lub neej ntev yog qhov nruab nrab.
Kev kho deg (piv txwv li, TiN txheej, TD txheej): Rau blanking 65Mn lossis siab -lub zog steel, TD kev kho mob tuaj yeem ua rau lub neej nce 5 ~ 10 npaug piv rau kev kho cua sov zoo tib yam. Tuag nrog TD kev kho mob tuaj yeem muaj peev xwm tshaj 2 lab lub voj voog rau cov hlau phaj tuab dua 3 hli.
Parallelism thiab Rigidity ntawm cov khoom siv
Yog hais tias cov xovxwm tsis zoo rigidity (loj deformation ntawm C- hom lub cev) los yog cov swb thiab lub rooj zaum ua hauj lwm tsis sib npaug, nws yuav ua rau cov pwm tsis sib npaug, uas ua rau hauv zos chipping thiab txo qis hauv nws lub neej kev pab cuam.
5.Yuav ua li cas kwv yees nws lub neej seem lossis txiav txim siab seb puas xav tau kev kho dua tshiab?
Burr Tshaj Tawm: Thaum qhov siab burr siab tshaj 0.1mm (los yog cov khoom siv tshwj xeeb), thiab sai sai dua tom qab rov- sib tsoo, nws qhia tau tias qhov tuag yuav tau nkag mus rau lub sijhawm qaug zog.
Nquag Chiping: Yog tias me me chipping tshwm sim ntau zaus tsis ntev los no, nws qhia tau hais tias cov hlau tuag substrate yuav qaug zog, thiab kev hloov nrog cov tuag tshiab yog pom zoo.
Lub suab nrov txawv txav: hnov lub suab nrov lossis lub suab nrov txawv txav thaum lub sij hawm stamping feem ntau txhais tau hais tias qhov kev tshem tawm tau nce los yog tawg tau tshwm sim.
