Punch, Tuag Thaiv, thiab Clearance Relationships

Kev sib raug zoo ntawm punch thiab tuag thaiv yog qhov kev txiav txim siab tau txais txiaj ntsig. Thaum lub punch nqis los rau hauv qhov qhib qhov tuag, cov khoom txiav nrog nqaim bands ntawm ob lub punch edge thiab tuag ntug. Qhov sib txawv ntawm ob qhov kev txiav tawm - qhov kev tshem tawm - txiav txim siab seb koj puas tau txais ib feem huv lossis tsis lees paub.

Rau steel workpieces, pom zoo tshem tawm khiav 5-10% ntawm cov khoom thickness ib sab. Ib daim ntawv 1.0 hli steel, piv txwv li, xav tau kwv yees li 0.05 txog 0.10 hli ntawm qhov chaw nruab nrab ntawm lub punch ntug thiab tuag khawm ntug ntawm txhua sab. Covpes tsawg feem pua ​​yog nyob ntawm workpiece hardness thiab tensile zog- cov ntaub ntawv softer xws li txhuas zaum ntawm qhov qis kawg, thaum siab - lub zog steel thawb mus rau 10% lossis siab dua.

Tau txais qhov tsis ncaj ncees lawm thiab peb qhov teeb meem tshwm sim:

• Tsawg heev clearance- Lub zog shear ntau dhau ua rau cov punch hnav, ua kom sov, thiab tuaj yeem ua rau cov cuab yeej tawg ncaj qha.
• Ntau dhau clearance- Cov ntaub ntawv khoov dua li txiav kom huv si, ua rau hnyav burrs thiab rollover ntawm ib feem ntug.
• Uneven clearance- Misalignment ntawm punch thiab tuag thaiv tsim tapered txiav thiab inconsistent burr qhov siab, ua rau ntxov ntxov hnav ntawm ib sab ntawm cov cuab yeej.

Kev tshem tawm kom raug kuj tseem txo cov quab yuam uas yuav tsum tau txiav cov khoom ua haujlwm, uas txo qis kev siv zog ntawm cov xovxwm thiab txuas ntxiv lub sijhawm ntawm cov nyiaj stamping tuag. Hauv cov hlau stamping tuag tsim rau siab - ntim ntau lawm, txawm tias 1-2% sib txawv los ntawm kev pom zoo tuaj yeem txiav cov cuab yeej lub neej los ntawm 30% lossis ntau dua.

Strippers thiab Spring Systems

Tom qab ib tug punch nkag mus rau lub workpiece, cov khoom tuav lub punch ntawm rov qab stroke. Yog tsis muaj stripper, daim ntawv nqa nrog lub punch, misfeeds ntawm qhov chaw nres tsheb tom ntej, thiab jams lub cuab yeej. Strippers daws qhov no los ntawm kev tuav cov khoom tiaj tus tiv thaiv lub ntsej muag tuag thaum lub punch thim rov qab.

Ob hom tseem ceeb muaj nyob rau daim ntawv thov hlau stamping. Tsau strippers yog bolted rigidly nyob rau hauv qhov chaw nrog qhov sib txawv machined kom tshem tawm cov khoom - yooj yim, ruaj, tab sis muab tsis muaj downward clamping siab. Caij nplooj ntoos hlav-loaded strippers nias cov khoom tiaj tus ua ntej lub punch tiv tauj nws thiab tswj lub siab thoob plaws hauv cov hlab ntsha, txhim kho kev txiav zoo thiab ib feem flatness.

Cov springs tsav cov strippers no tuaj nyob rau hauv ob hom. Mechanical tuag springs - xim -coded helical coils - yog cov qauv xaiv rau cov khoom nruab nrab. Nitrogen gas springs xa cov quab yuam ntau dua nyob rau hauv ib lub pob me me thiab muab kev sib tw ntau dua nyob rau hauv tag nrho cov hlab ntsha tawg, ua rau lawv nyiam rau kev sib sib zog nqus sib sib zog nqus thiab kos cov haujlwm uas tsis muaj kev tuav pov hwm yog qhov tseem ceeb.

Xaiv txoj cai caij nplooj ntoos hlav preload thiab mus ncig. Underloaded springs cia cov khoom nqa thaum lub sij hawm xuas nrig ntaus, tsim burrs thiab slug rub. Overloaded springs pov tseg xovxwm tonnage thiab ua kom qaug zog. Lub caij nplooj ntoos hlav system yuav tsum sib npaug stripping quab yuam tawm tsam tag nrho cov xovxwm muaj peev xwm - ib qho kev suav uas txuas ncaj qha rov qab mus rau tus naj npawb ntawm cov chaw nres tsheb thiab cov kev sib txuas ua ke hla txhua qhov punches hauv lub cuab yeej.

Txhua yam ntawm cov khoom no tau tsim los ntawm cov cuab yeej tshwj xeeb steel qib, machined kom nruj tolerances, thiab tom qab ntawd hardened los tiv thaiv cov repetitive cuam tshuam loads uas ntau lawm stamping xav tau. Kev xaiv steel - thiab yuav kho li cas - yog qhov kawg txiav txim siab seb tus neeg tuag puas muaj sia nyob nws lub hom phiaj lub neej los yog hnav tawm ntxov ntxov.

Xaiv Tuag Hlau thiab Cov Khoom Siv Rau Lub Neej Ntev

Ib qho tuag ua los ntawm qib hlau tsis raug yog qhov tuag nrog hnub tas sij hawm stamped rau nws txij hnub ib. Lub geometry tuaj yeem ua tau zoo, qhov kev tshem tawm tau raug hu rau hauv, thiab cov qauv strip optimized - tab sis yog tias cov cuab yeej hlau tsis tuaj yeem tuav lub zog, qhov kub thiab txias, nws yuav ntsib txhua qhov mob stroke, hnav ntxov ntxov lossis kev puas tsuaj loj yuav raug kaw. Xaiv cov khoom siv hlau stamping zoo tsis yog qhov kev txiav txim siab thib ob. Nws yog ib qho loj tshaj plaws nyob rau hauv seb ib tug tuag ciaj sia 50,000 hits los yog 5,000,000.

Qhov kev sib tw yog tias tsis muaj ib qib steel tswj txhua qhov xwm txheej. Lub blanking punch txiav stainless hlau stamping kev ua haujlwm xav tau kev hnav tsis kam, thaum lub chaw tsim khoom kos duab aluminium stamping tseem ceeb tshaj qhov toughness thiab nto tiav dhau hardness. Koj yuav tsum phim cov hlau rau peb qhov sib txawv ib txhij: cov khoom siv ua haujlwm, hom kev ua haujlwm, thiab qhov xav tau ntim.

Cov cuab yeej Steel Qib rau cov khoom siv sib txawv

Tsib lub cuab yeej steel qib npog feem ntau ntawm cov ntawv thov stamping tuag. Txhua tus nyob hauv ib txoj hauj lwm sib txawv ntawm qhov hardness-vim-toughness spectrum, thiab nkag siab qhov twg txhua tus excels tiv thaiv tus nqi tsis sib haum.

D2yog lub workhorse ntawm stamping tuag siv. Nws cov ntsiab lus chromium siab (kwv yees li 12%) tsim ntau cov qauv carbide uas tiv thaiv kev hnav tsis zoo. Rau kev ua haujlwm blanking thiab tho rau ntawm me me thiab nruab nrab - carbon stamped steel, D2 muab lub neej ua haujlwm ntev ntawm tus nqi tsim nyog. Kev sib pauv? Cov tib lub pas dej loj carbide uas txhawb nqa kev tiv thaiv kom tsis txhob muaj kev cuam tshuam toughness. D2 punches nyob rau hauv nyias cross-sections los yog ntse ces kaum yog feem ntau ua rau chipping nyob rau hauv hnyav shock loads.

A2muaj lwm txoj kev zam txim ntxiv. Nws yog huab cua- hardening steel nrog zoo seem stability thaum lub sij hawm kho cua sov dua D2, thiab nws ua rau muaj kev cuam tshuam nruab nrab yam tsis muaj cracking. Rau cov khw muag khoom nruab nrab- ntim ntau lawm - kwv yees li 100,000 txog 1,000,000 qhov chaw - A2 muab kev sib npaug ntawm kev ua haujlwm thiab tus nqi. Nws tshuab tau yooj yim dua ua ntej hardening thiab distorts tsawg dua tom qab, uas txo cov sij hawm sib tsoo.

S7zaum ntawm qhov toughness kawg ntawm lub spectrum. Thaum cov tuag ua haujlwm hnyav, sib sib zog nqus dabtsi yog khoov, lossis ib qho kev ua haujlwm uas muaj kev cuam tshuam tam sim ntawd, S7 absorbs lub zog poob siab yam tsis muaj kev tawg. Tsim cov chaw nres tsheb uas zoo li tuab - ntsuas steel lossis siab- lub zog alloys feem ntau qhia S7 vim tias nws tiv taus hom kev tawg uas yuav ua rau cov qib nyuaj, nkig dua. Kev txi yog hnav lub neej - S7 hnav sai dua D2 nyob rau hauv abrasive tej yam kev mob thiab feem ntau xav tau ntau zaus regrinding.

M2 siab -ceev steelnqa qhov hnyav hnyav (txog 65 HRC) thiab khaws nws cov ntug txiav txawm tias qhov kub siab. Rau kev tho kev khiav haujlwm ntawm cov hlab ntsha siab, lossis thaum txiav siab siab siab - lub zog steel thiab lwm yam khoom siv ua haujlwm abrasive, M2 outlass cov pa txias- ua haujlwm steels los ntawm cov npoo dav. Tus nqi hwm yog qhov tseem ceeb, yog li M2 zoo li tshwm sim raws li tus neeg punch inserts es tsis yog tag nrho cov blocks tuag.

dc53 uayog qhov hloov kho txias- ua haujlwm steel tsim los hais txog D2 lub ntsiab tsis muaj zog. Nws ua tiav qhov hardness zoo sib xws (60-62 HRC) nrog kwv yees li ob npaug ntawm qhov hnyav ntawm tus qauv D2, ua tsaug rau qhov zoo dua, zoo dua carbide faib. Rau blanking tuab- ntsuas steel lossis siab- cov ntaub ntawv tensile qhov twg ob qho tib si hnav tsis kam thiab poob siab tsis kam, DC53 sau qhov sib txawv uas D2 thiab S7 tawm ntawm lawv.

Cov khoom siv workpiece tsav ib feem loj ntawm kev xaiv logic. Stamping cov ntaub ntawv mos zoo li txhuas yuav tsum tsis txhob hnav tsis kam, tab sis xav tau qhov zoo tshaj plaws ntawm qhov kawg kom tiv thaiv kev kub nyhiab - txhuas hlau stamping ua haujlwm feem ntau tau txais txiaj ntsig los ntawm polished A2 lossis coated tool steels es tsis yog raw D2. Stainless hlau stamping yog qhov sib txawv heev: cov khoom yog abrasive, ua hauj lwm- hardens sai, thiab generates hluav taws xob tseem ceeb, uas hu rau siab -chromium los yog siab - ceev steels nrog robust nto txheej. Me me thiab qis- carbon stamped steel ntog nyob rau hauv nruab nrab, qhov twg D2 ua haujlwm feem ntau ntawm cov blanking thiab tho ua hauj lwm yam tsis muaj teeb meem.

Carbide thiab hmoov Metallurgy Alternatives

Thaum cov khoom ntim tau thawb mus rau ntau lab, lossis thaum cov khoom siv ua haujlwm tshwj xeeb yog abrasive, cov cuab yeej siv tau zoo mus txog lawv qhov kev txwv. Qhov ntawd yog qhov uas carbide thiab hmoov metallurgy (PM) steels nkag mus rau hauv daim duab.

Tungsten carbide inserts muab kev hnav tsis kam uas ua rau lub neej tuag los ntawm 500-1,000% piv rau cov cuab yeej ib txwm siv hauv qee yam kev siv. Lawv ua tau zoo nyob rau hauv nplua blanking, precision tho ntawm cov ntaub ntawv tuab, thiab txhua qhov chaw nres tsheb qhov punch lossis tuag qhib kev paub txog kev sib cuag tsis tu ncua. Kev ntes yog brittleness - carbide tsis tuaj yeem ua rau sab loads, misalignment, lossis hnyav hnyav. Ib qho carbide ntxig rau hauv qhov chaw nres tsheb tsis zoo yuav tawg sai sai qhov twg D2 tsuas yog hnav.

Cov hmoov hlau metallurgy zoo li ASP-60, CPM-10V, thiab Vanadis 4 Ntxiv txuas qhov sib txawv ntawm cov cuab yeej siv hlau thiab cov carbide. PM cov txheej txheem tsim khoom tsim tau zoo heev, tsis sib xws carbide faib thoob plaws hauv cov hlau matrix, uas tshem tawm cov pas dej loj carbide pom nyob rau hauv cov qib cam khwb cia.
