Ndifumana ii-imeyile ezininzi rhoqo ngenyanga kwaye ndinqwenela ukuba ndibe nexesha lokuphendula kuzo zonke.Kodwa ke, akukho xesha elaneleyo kwimini yokwenza konke.Kwikholomu yale nyanga, ndidibanise ii-imeyile ezimbalwa endiqinisekileyo ukuba abafundi bam abaqhelekileyo baya kufumana luncedo.Ngeli nqanaba, makhe siqale ukuthetha malunga nemiba enxulumene nokuhlelwa.
Umbuzo: Ndifuna ukuqala ngokuthi ubhala inqaku elihle kakhulu.Ndibafumene beluncedo kakhulu.Ndiye ndinzima ngomcimbi kwi-software yethu yeCAD kwaye andinakubonakala ngathi ndifumana isisombululo.Ndidala ubude obungenanto kwi-hem, kodwa isofthiwe ihlala ibonakala ifuna isibonelelo esongezelelweyo sokugoba.Umqhubi wethu we-brake undixelele ukuba ndingashiyi isibonelelo sokugoba kwi-hem, ngoko ke ndivumele i-software ye-CAD ukuba ibeke ubuncinci besoftware. (0.008 ″) - kodwa ndaphelelwa sisitokhwe.
Ngokomzekelo, ndine-16-ga.304 yensimbi engenasici, imilinganiselo yangaphandle i-2 "kunye ne-1.5", i-0.75 ". I-Hem ukuya ngaphandle. Abaqhubi bethu be-brake baye banquma ukuba isibonelelo se-bend siyi-0.117 intshi. 0.117), sifumana ubude besitokisi se-intshi ze-4.132. Nangona kunjalo, izibalo zam zandinika ubude obufutshane obungenanto (i-4.018 intshi) .Ngako konke okuthethiweyo, sibala njani i-flat blank for the hem?
A: Okokuqala, makhe sicacise amagama ambalwa. Ukhankanye isibonelelo se-bend (BA) kodwa awuzange ukhankanye ukutsalwa kwe-bend (BD), ndiqaphele ukuba awuzange udibanise i-BD yokugoba phakathi kwe-2.0 "kunye ne-1.5" .
I-BA kunye ne-BD zihluke kwaye azitshintshi, kodwa ukuba uzisebenzisa ngokuchanekileyo, zombini zikuthatha kwindawo efanayo.BA ngumgama ojikeleze i-radius elinganiswe kwi-axis engathathi hlangothi.Emva koko yongeza loo nombolo kwimilinganiselo yakho yangaphandle ukukunika ubude obungenanto obucacileyo.BD ikhutshwe kwimilinganiselo yonke yomsebenzi, i-bend enye ngokugoba.
Umzobo 1 ubonisa umahluko phakathi kwezi zimbini. Qinisekisa ukuba usebenzisa echanekileyo. Qaphela ukuba amaxabiso e-BA kunye ne-BD anokwahluka ukusuka kwi-bend ukuya kwi-bend, kuxhomekeke kwi-engile yokugoba kunye ne-radius yokugqibela yangaphakathi.
Ukubona ingxaki yakho, usebenzisa i-0.060″ engqindilili engama-304 yentsimbi ejiyileyo kunye ne-2.0 kunye ne-1.5″ ngaphandle kwemilinganiselo, kunye no-0.75″.Umphetho emphethweni.Kwakhona, awuqukanga ulwazi malunga ne-engile yokugoba kunye ne-bend radius yangaphakathi, kodwa ukuze kube lula ndibale i-engile ye-4 ndenze i-engile ye-20 emoyeni. I-intshi.die.Oku kukunika i-0.099 intshi.I-Floating bend radius, ibalwa ngokusebenzisa umgaqo we-20%. (Ukufumana okungakumbi kumgaqo we-20%, unokujonga "Indlela yokuqikelela ngokuchanekileyo i-Inner Bend Radius ye-Air Formation" ngokuchwetheza isihloko kwibhokisi yokukhangela ye-thefabricator.com.
Ukuba i-0.062 intshi.I-punch radius igoba izinto ezingaphezu kwe-0.472 intshi.Ukuvulwa kweDie, ufezekise i-0.099 intshi.Ukudada ngaphakathi kwi-bend radius, i-BA yakho kufuneka ibe yi-intshi ye-0.141, ukubuyisela ngaphandle kufuneka kube yi-0.125 intshi, kunye nokunciphisa i-bend phakathi kwe-BD10 kufuneka usebenzise i-intshi ye-bend ye-BD1. I-1.5 kunye ne-2.0 intshi. (Unokufumana iifomyula ze-BA kunye ne-BD kwikholamu yam yangaphambili, kuquka "iSiseko sokuSebenzisa iMisebenzi yokuGobela.")
Emva koko, kufuneka ubale ukuba utsalwe ntoni kwi-hem.Phantsi kweemeko ezigqibeleleyo, i-deduction factor for flat or closed hems (izinto ezingaphantsi kwe-0.080 intshi ubukhulu) yi-43% yobunzima bezinto eziphathekayo. Kule meko, ixabiso kufuneka libe yi-0.0258 intshi.
0.017 intshi.Umahluko phakathi kwexabiso lakho elingenanto elicwecwe le-intshi ze-4.132 kunye neyam ye-4.1145 intshi inokucaciswa ngokulula yinto yokuba i-hemming ixhomekeke kakhulu kumqhubi.ndithetha ukuthini?Kulungile, ukuba umqhubi ubetha inxalenye ethe tyaba yenkqubo yokugoba ngakumbi, uya kufumana i-flange ende.Ukuba umqhubi we-flange akayi kubetha ngokwaneleyo ekugqibeleni.
Umbuzo: Sinesicelo sokugoba apho senza i-metal sheets ezahlukeneyo, ukusuka kwi-20-ga.I-Stainless ukuya kwi-10-ga.Impahla efakwe ngaphambili.Sine-brake ye-press kunye nokulungelelaniswa kwesixhobo esizenzekelayo, i-V-die ehlengahlengiswayo phantsi kunye ne-self-positioning segmented punch phezulu.Ngelishwa, senze iphutha kwaye sayalela i-punch6 i-radio3us0.
Sisebenza ekufumaneni ubude bethu be-flange buhambelanayo kwinxalenye yokuqala.Kwacetyiswa ukuba isofthiwe yethu ye-CAD isebenzisa ukubala okungalunganga, kodwa inkampani yethu yesofthiwe yabona ingxaki kwaye yathi sasilungile.Ingaba iya kuba yi-software yomshini wokugoba? Okanye ngaba sicinga ngokugqithiseleyo? Ngaba luhlengahlengiso oluqhelekileyo lwe-BA okanye sinokufumana i-punch entsha kunye ne-0.032 yolwazi oluya kuluxabisa.
A: Ndiza kujongana noluvo lwakho malunga nokuthenga i-radius ye-punch engalunganga kuqala.Ngenxa yohlobo lomatshini onalo, ndicinga ukuba ubumba umoya.Oku kundikhokelela ukuba ndibuze imibuzo emininzi.Okokuqala, xa uthumela umsebenzi kwivenkile, uxelela umqhubi ukuba yeyiphi i-mold i-design yokuvula inxalenye eyenziwe?Yenza umahluko omkhulu.
Xa i-airform inxalenye, i-radius yokugqibela yangaphakathi yenziwa njengepesenti yokuvula i-mold.Lo ngumgaqo we-20% (jonga umbuzo wokuqala ukuze ufumane ulwazi oluthe kratya) .Ukuvulwa kweefa kuchaphazela i-radius ye-bend, echaphazela i-BA kunye ne-BD.Ngoko ukuba ukubala kwakho kubandakanya i-radius eyahlukileyo enokufezekiswa yokuvula ukufa kuneyona nto isetyenziswa ngumqhubi kumatshini, unengxaki.
Masithi umatshini usebenzisa ububanzi bokufa obuhlukeneyo kunokuba bekucwangcisiwe.Kule meko, umatshini uya kufezekisa i-radius ye-bend yangaphakathi eyahlukileyo kunokuba bekucwangcisiwe, ukuguqula i-BA kunye ne-BD, kwaye ekugqibeleni imilinganiselo eyenziwe yinxalenye.
Oku kundizisa kuluvo lwakho malunga neradius yepunch engalunganga.0.063″ ngaphandle kokuba uzama ukufumana iradiyasi eyahlukileyo okanye encinci yangaphakathi yokugoba.Iradiyasi kufuneka isebenze kakuhle, yiyo loo nto.
Ukulinganisa irediyasi egobileyo yangaphakathi efunyenweyo kwaye uqinisekise ukuba ihambelana neradiyasi egobileyo engaphakathi.Ingaba irediyasi yakho yepunch ayilunganga ngokwenene?Kuxhomekeke kwinto ofuna ukuyiphumeza.Iradiyasi yepunch kufuneka ilingane okanye ilingane okanye ilingane neradiyasi edadayo yangaphakathi yokugoba.Ukuba iradiyasi yepunch inkulu kuneradiyasi yendalo edadayo kwigophe elinikiweyo, inxalenye iyakuphinda itshintshe iradiyasi engaphakathi. ubale iBA kunye neBD.
Kwelinye icala, awufuni ukusebenzisa iradiyasi yenqindi encinci kakhulu, enokulola igophe kwaye ibangele ezinye iingxaki ezininzi.
Ngaphandle kwezi zimbini zigqithise, i-punch kwifom yomoya ayikho into kodwa iyunithi yokutyhala kwaye ayichaphazeli i-BD kunye ne-BA. Kwakhona, i-radius ye-bend ibonakaliswe njengepesenti yokuvula ukufa, kubalwa ngokusebenzisa umthetho we-20%.
Umbuzo: Ndizama ukubala awona mandla asemacaleni aphezulu kwisixhobo sokurhawula esiqhelekileyo ukuqinisekisa ukuba abasebenzi bethu bakhuselekile ngexesha lenkqubo yokurhawula. Ingaba unawo nawaphi na amacebiso okundinceda ndifumane oku?
Impendulo: I-Lateral force okanye i-lateral thrust inzima ukulinganisa kunye nokubala ukulinganisa i-hem kwi-brake ye-press kwaye kwiimeko ezininzi akuyimfuneko.Ingozi yokwenene igqithise i-brake ye-press kunye nokutshabalalisa i-punch kunye nebhedi yomshini.
Umzobo 2. Iipleyiti ezityhutyhayo kwiseti yee-flatening dies ziqinisekisa ukuba izixhobo eziphezulu nezisezantsi azihambi kumacala achaseneyo.
I-brake ye-press ngokuqhelekileyo iphosakele phantsi komthwalo kwaye ibuyele kwindawo yayo yasekuqaleni xa umthwalo ususiwe. Kodwa ukudlula umda womthwalo weebhuleki unokugoba iindawo zomatshini ukuya kwindawo apho zingasayi kubuyela kwindawo ephantsi. Oku kunokonakalisa ngokusisigxina i-brake yokushicilela. Ngoko ke, qiniseka ukuba uqwalasela imisebenzi yakho ye-hemming kwizibalo ze-tonnage.
Ukuba i-flange iya kucandwa ide ngokwaneleyo ukuba ityabeke, i-thrust yecala kufuneka ibe yincinci.Nangona kunjalo, ukuba ufumanisa ukuba i-thrust yecala ibonakala igqithise kwaye ufuna ukunciphisa intshukumo kunye nokujika kwe-mod, ungongeza iipleyiti zokutyhala kwi-mod. iqinisekisa ukuba izixhobo eziphezulu nezisezantsi azihambi ngendlela echaseneyo komnye nomnye (jonga umfanekiso 2).
Njengoko benditshilo ekuqaleni kolu luhlu, mininzi kakhulu imibuzo kwaye lincinci ixesha lokuyiphendula yonke. Ndiyabulela ngomonde wenu ukuba nisandula ukundithumelela imibuzo.
Kuyo nayiphi na imeko, vumela imibuzo iqhubeke ivela.Ndiza kubaphendula ngokukhawuleza.Kuze kube ngoko, ndiyathemba ukuba iimpendulo apha ziya kunceda abo babuze umbuzo kunye nabanye abajongene nemiba efanayo.
Ukutyhila iimfihlo zokusebenzisa i-press brake kule workshop yeentsuku ezimbini ezinzulu ngo-Agasti 8-9 kunye nomqeqeshi uSteve Benson ukuba akufundise ithiyori kunye neziseko zemathematika emva komatshini wakho.Uya kufunda imigaqo esemva komgangatho ophezulu wokugoba isinyithi ngokusebenzisa umyalelo osebenzisanayo kunye neengxaki zomsebenzi wesampuli kulo lonke ikhosi.Ngokulula-ukuyiqonda lula i-extra-ukuqonda i-extracts efunekayo ukuze ukhethe izakhono ezichanekileyo zokuzilolonga, uya kuba nokufunda izakhono ezichanekileyo, ufunde izakhono ezichanekileyo, funda izakhono ezichanekileyo, ufunde izakhono ezichanekileyo. misela i-V-die echanekileyo yokuvula ukunqanda ukugqwesa inxalenye.Ndwendwela iphepha lesiganeko ukuze ufunde ngakumbi.
