Progressive Dies yog dab tsi?
Cov khw muag khoom hlau stamping khiav nrawm tuag thaum lawv xav tau ntau txhiab tus tib yam. Lub sawb pub tawm ntawm ib lub kauj, mus txog qhov tuag, thiab ib qho tiav lawm poob tawm tom qab. Txhua qhov kev ntaus xovxwm ua txhua yam haujlwm ib zaug.
Kuv pom txiv neej hu lawv prog tuag rau hauv pem teb. Qee cov neeg laus tseem hais tias cov neeg laib tuag tab sis cov lus ntawd poob tawm ntawm kev siv nyob ib ncig ntawm 80s.
Lub tswv yim yooj yim
Koj tau txais ib daim kab xev. Yuav yog .020 txias dov, tuaj yeem yog .062 stainless, txawm tias txoj haujlwm hu rau. Lub strip indexes los ntawm qhov tuag ib lub suab ntawm ib lub sij hawm. Chaw nres tsheb 1 tuaj yeem xuas koj lub qhov tsav. Chaw nres tsheb 2 punches ib qhov. Chaw nres tsheb 3 muab ib tug lance rau hauv. Chaw nres tsheb 4 ua koj thawj daim ntawv. Thiab yog li ntawm txoj kab nqes mus txog rau thaum lub chaw nres tsheb kawg txiav tawm ntawm tus cab kuj.
Tus cab kuj yog dab tsi tuav txhua yam ua ke. Koj xav tau cov ntaub ntawv txaus ntawm ob sab kom tsis txhob flopping ib ncig. Nyuaj dhau lawm thiab lub strip taug kev. Dav dav heev thiab koj nkim khoom. Feem ntau cov hauj lwm kuv pom cov cab kuj ntawm 3 thiab 6 hli nyob ntawm cov khoom thickness.
Vim li cas Pilots tseem ceeb
Pilots nrhiav lub strip ua ntej xovxwm kaw. Yog tsis muaj tus tsav zoo koj tau txais kev ua yuam kev loj zuj zus. Qhov ntawd txhais tau hais tias txhua qhov chaw nres tsheb ntxiv me ntsis ntawm misalignment kom txog rau thaum koj ob peb txoj haujlwm dhau los dhau los.
Round pilots ua haujlwm zoo rau ntau txoj haujlwm. Qee lub khw siv pob zeb diamond pilots rau thawj zaug rub tawm ib qho nqes hauv qhov pub. Kuv tau ua haujlwm ntawm ib qho chaw hauv Michigan uas tau cog lus los ntawm cov neeg tsav tsheb lub qhov ntswg tab sis ncaj ncees kuv yeej tsis pom qhov txawv ntau.
Koj tus kws tsav dav hlau mus rau qhov kev tshem tawm khiav tej zaum .0003 txog .0008 ntawm txoj kab uas hla. Tighter tshaj qhov ntawd thiab koj tau qhab nia lub qhov. Looser thiab koj swb lub hom phiaj.
Chaw nres tsheb ib ntus
Tsis muaj cov mis mos ntawm no. Koj ntxhib tawm cov kab ke raws li cov yam ntxwv yuav tsum tau mus ua ntej.
Pilots ib txwm mus ntxov. Qhov ua ntej daim ntawv. Lance ua ntej khoov yog tias tus lance nyob ze ntawm txoj kab khoov. Cutoff mus kawg.
Qee zaum koj xav tau chaw nres tsheb tsis ua haujlwm. Hais tias koj tau txais ib daim ntawv uas xav tau kev tshem tawm hauv qab thiab tsis muaj chaw nrog cov punch uas nyob ib sab. Koj hla chaw nres tsheb. Tus nqi koj ib co strip tab sis daws qhov cuam tshuam.
Cov chaw nres tsheb sib txuas ua ob yam hauv ib zaug. Piv txwv li, ib tug pierce thiab ib daim ntawv ntawm opposite sab ntawm lub strip piv txwv li. Txuag lub suab ntev tab sis ua rau tuag ntau nyuaj los tsim thiab tswj.
Txoj kev loj hlob
Nov yog qhov uas cov txiv neej ntsia hlau. Koj yuav tsum nthuav tawm ib feem thiab txheeb xyuas seb koj xav tau cov ntaub ntawv ntau npaum li cas. Qhov loj me me yuav tsum suav rau cov nyiaj khoov. Cov khw sib txawv siv qhov sib txawv K. Kuv siv .42 rau cua khoov ntawm cov hlau me me hauv qab 90 degrees. Nws nce los ntawm qhov ntawd.
Thaum koj tau txais koj qhov khoob ua haujlwm tawm koj pom lub suab. Qhov ntev ntxiv rau lub vev xaib ntawm qhov chaw. Lub vev xaib yuav tsum txaus kom koj tsis txhob cuam tshuam thaum koj xuas nrig ze ntawm ntug. Txoj cai ntawm tus ntiv tes xoo yog 1.5T yam tsawg kawg nkaus. Cov hauj lwm loj tshaj plaws kuv pom khiav 2T kom muaj kev nyab xeeb.
Strip width yog qhov dav dav ntxiv rau ob lub cab kuj ntxiv rau trim. Ntawm qhov nqaim koj tuaj yeem khiav ob lossis peb tawm kom tau txais kev siv zoo dua. Qhov ntawd txhais tau hais tias ntau qhov chaw hla lub strip dav.
Pub
Kev ua haujlwm tuag feem ntau yog siv cua txau lossis servo pub. Roll feeds ua hauj lwm ib yam nkaus tab sis lawv plam ntawm oily Tshuag. Pub yuav tsum tau teem sijhawm rau cov xovxwm. Yog tias cov khoom noj nce ntxiv thaum cov tsav tsheb tseem nyob hauv qhov koj rhuav tshem lub sawb.
Pub ntev qhov tseeb tseem ceeb tshaj li cov neeg xav. Ntawm qhov tuag khiav 300 strokes ib feeb ib qho .002 pub yuam kev txhua qhov ntaus ntxiv nrawm. Los ntawm lub sij hawm koj nyob ib nrab ntawm ib tug coil koj tawm ntawm kam rau ua.
Misfeeds tshwm sim. Nws tuaj yeem yog roj rau ntawm cov yob. Tej zaum yuav yog ib lub kauj nrog nruj me ntsis. Yuav yog lub voj tswj kev ua haujlwm. Feem ntau cov tuag muaj misfeed nrhiav pom. Lub sensor kuaj xyuas qhov pilot qhov nyob rau hauv qhov chaw. Yog tsis muaj xovxwm nres.
Tonnage
Xovxwm tonnage yuav tsum npog tag nrho koj cov kev txiav thiab tsim cov rog ntxiv rau qee qhov kev nyab xeeb. Ntxiv rau qhov perimeters ntawm tag nrho koj cov kev txiav thiab muab faib los ntawm cov khoom thickness thiab shear zog. Qhov ntawd yog koj txiav tonnage. Forming tonnage nyob ntawm qhov khoov ntev thiab V tuag qhib. Muaj cov kab kos rau qhov no.
Kuv tau pom cov txiv neej qhov loj ntawm cov xovxwm ntawm 1.5 npaug suav tonnage. Qhov no suav nrog dull punches thiab tawv me ntsis hauv cov khoom.
Rov qab tonnage tseem ceeb heev. Lub snapthrough thaum lub punch tsoo los ntawm cov khoom. Shock loads li ntawd hnav tawm presses thiab tawg khau tuag. Shear ntawm cov punches pab nthuav tawm lub nra.
Punch thiab Tuag Clearance
Clearance tsis yog tib yam rau txhua yam khoom. Mos aluminium tej zaum khiav 6 feem pua ntawm cov tuab ntawm ib sab. Txias dov steel ze rau 8 feem pua. Stainless li ntawm 10 lossis 12 feem pua.
nruj dhau thiab koj tau txais kev sib tw thib ob ntawm qhov txiav ntug. Zoo li ob txoj kab tawg. Kuj hnav tawm koj cov punches sai dua. Tshaj dhau thiab koj tau rollover thiab hnyav burr.
Kuv kos clearance nrog ib tug hlau gauge. Los yog koj tuaj yeem xiav li ib daim ntawv xeem thiab saib qhov so. Koj xav tau tej zaum ib feem peb shear thiab ob feem peb so rau feem ntau daim ntawv thov.
Cov khoom siv tuag
Punches thiab tuag nyees khawm feem ntau yog cov cuab yeej hlau. D2 yog ntau. Siv sijhawm ntev npaum li cas ntawm cov hlau me me. M2 kev kub ceev rau cov ntaub ntawv abrasive los yog khiav ntev. Carbide rau qhov ntim siab tiag tiag lossis stainless uas noj txhua yam.
Cov khau tuag yog A36 lossis cam khwb cia hlau. Qee lub khw mus nrog aluminium tuag teeb ntawm lub teeb ua haujlwm. Txuag qhov hnyav thaum koj swapping tuag ntawm lub xovxwm me me.
Strippers tuaj yeem yog cov cuab yeej hardened steel lossis bronze. Bronze ua haujlwm zoo thaum koj xav tau lub stripper los tiv tauj cov qauv tsim yam tsis muaj cim rau lawv.
Dab tsi mus yuam kev
Slug rub yog qhov loj. Lub slug sticks rau lub ntsej muag punch thiab rov qab los. Tom ntej no ntaus koj tau txais ib tug slug ntawm lub punch thiab tuag thiab ib yam dab tsi so. Polished punch ntsej muag pab. Zoo li lub tshuab nqus tsev los ntawm lub pob tuag. Qee tus txiv neej cog lus los ntawm lub caij nplooj ntoos hlav loaded ejector pins tab sis lawv ntxiv complexity.
Punch galling qhia txog stainless thiab aluminium. Cov khoom welds rau lub punch. Txheej txheej pab. TIB or TiCN. Qee lub khw siv Lubricool los yog cov roj zoo sib xws. Chlorinated lub cev ua haujlwm zoo tab sis tsis muaj leej twg xav nrog kev pov tseg ntxiv lawm.
Carrier strip tawg feem ntau txhais tau tias koj lub vev xaib nqaim dhau los lossis koj cov neeg tsav tsheb nruj dhau. Lossis ib tug neeg khiav xovxwm ceev heev. Lub strip tau ua hauj lwm hardened thaum nws mus dhau thiab nws thiaj li tawg.
Kev tu
Lub sijhawm sib txawv yog nyob ntawm txoj haujlwm. Cov hlau me me koj tuaj yeem tau txais 100000 hits ntawm sharpens. Stainless tej zaum 30000. Silicon steel rau lub cev muaj zog laminations txawm tsawg.
Thaum koj sharpen koj yuav tsum khaws txhua yam txawm. Siv .002 tawm ntawm cov punches thiab .002 tawm ntawm qhov thaiv tuag. Txwv tsis pub koj qhov siab kaw tau tawm ntawm whack thiab koj qhov kev tshem tawm mus tsis zoo.
Pilots hnav thiab. Cov khw feem ntau hloov cov tsav tsheb thaum lawv poob .001 los yog li ntawm txoj kab uas hla. Yav dhau los uas koj pib pom teeb meem qhov chaw.
Kuv tau khiav tuag dhau los 10 lab hits ntawm txoj haujlwm yooj yim. 2 lossis 3 lab yog ntau dua ua ntej koj xav tau kev ua haujlwm tseem ceeb. Carbide tooling kav ntev dua tab sis raug nqi ntau dua pem hauv ntej.
Muab piv rau Lwm Txoj Kev
Ib leeg ntaus tuag ua ib qho haujlwm. Koj txhais tes hloov qhov khoob ntawm qhov tuag. Yooj yim tab sis pheej yig tooling.
Hloov tuag siv cov cuab yeej siv ntiv tes txav mus rau ib tus neeg qhov khoob los ntawm ntau qhov chaw nres tsheb. Ua haujlwm rau qhov loj dua qhov uas lub sawb yuav hnyav dhau. Los yog qhov chaw nrog sib sib zog nqus rub uas xav tau ntau yam kev txo qis.
Progressive tuag ua rau kev nkag siab thaum koj tau ntim. Cov cuab yeej raug nqi ntau dua tab sis koj ua nws rov qab rau lub sijhawm voj voog. Hauv qab no tej zaum 50000 daim ib xyoo koj zaum mus nrog ib leeg ntaus. Tshaj li ob peb puas txhiab qhov kev vam meej feem ntau yeej.
Qhov twg Lawv Tau Siv
Hluav taws xob tiv tauj. Terminal pins. Brackets. Caij nplooj ntoos hlav clips. Motor laminations. Lead ncej rau semiconductors. Cov tab me me uas tuav cov roj teeb hauv qhov chaw. Tiv thaiv cov kaus poom rau kev siv RF.
Txhua qhov chaw koj xav tau ntau yam me me mus rau nruab nrab qhov loj me hauv cov ntawv hlau muaj tej zaum yuav muaj kev vam meej ua rau nws.
Cov khoom kho mob khiav hauv kev nce qib tuag ib yam nkaus. Kev phais staples. Implant Cheebtsam. Cov hauj lwm no muaj cov ntaub ntawv ntau dua thiab kev tswj cov txheej txheem nruj dua tab sis cov cuab yeej siv tuag zoo ib yam.
