Ngithola ama-imeyili amaningi njalo ngenyanga futhi ngifisa sengathi ngabe nginesikhathi sokuwaphendula wonke.Kodwa maye, asikho isikhathi esanele ngosuku sokwenza konke.Kukholomu yale nyanga, ngihlanganise ama-imeyili ambalwa engiqinisekile ukuthi abafundi bami abavamile bazothola ewusizo.Kuleli qophelo, ake siqale ukukhuluma ngezinkinga ezihlobene nesakhiwo.
UMB: Ngifuna ukuqala ngokuthi ubhala isihloko esihle kakhulu. Ngithole ukuthi ziwusizo kakhulu. Benginenkinga yesofthiwe ye-CAD futhi angikwazi ukuthola isisombululo. Ngidala ubude obungenalutho kumphetho, kodwa isofthiwe ibonakala idinga ukugoba okungeziwe. U-opharetha wethu wamabhuleki wangitshela ukuthi ngingashiyi imvume yokugoba yomphetho we-software, ngakho-ke ngivumele i-0 yesofthiwe ye-0, ngakho-ke ngivumele i-800 ye-software. Ngisaphelelwa isitokwe.
Isibonelo, nginensimbi engagqwali engu-16-ga.304, ubukhulu bangaphandle bungu-2″ no-1.5″, 0.75″.Umphetho ukuya ngaphandle.Ama-brake opharetha ethu anqume ukuthi isibonelelo sokugoba singamayintshi angu-0.117. Uma sengeza ubukhulu nomphetho, bese sikhipha +2 sithola i-bend 7 - 1 isitokwe. ubude obungamayintshi angu-4.132. Nokho, izibalo zami zinginikeze ubude obungenalutho obufushane (amayintshi angu-4.018).Ngakho konke okushiwo, singabala kanjani isikhala esingenalutho somphetho?
A: Okokuqala, ake sicacise amatemu ambalwa.Ukhulume ngesibonelelo sokugoba (BA) kodwa awuzange ukhulume ngokudonswa kwe-bend (BD), ngiqaphele ukuthi awuzange uyifake i-BD yamagobe aphakathi kuka-2.0″ no-1.5″.
I-BA ne-BD zihlukile futhi azishintsheki, kodwa uma uzisebenzisa ngendlela efanele, zombili zikuyisa endaweni efanayo.I-BA iyibanga elizungeza irediyasi elinganiswa ku-eksisi engathathi hlangothi.Bese wengeza leyo nombolo kubukhulu bakho bangaphandle ukuze unikeze ubude obungenalutho obuyisicaba.I-BD ikhishwa kubukhulu obuphelele bocezu lokusebenza, ukugoba okukodwa ngakunye.
Umfanekiso 1 ubonisa umehluko phakathi kwakho kokubili. Vele uqiniseke ukuthi usebenzisa okulungile. Qaphela ukuthi amanani we-BA kanye ne-BD angase ahluke ukusuka ekugotshweni kuye kwelinye, kuye nge-engeli yokugoba kanye nerediyasi yokugcina yangaphakathi.
Ukuze ubone inkinga yakho, usebenzisa insimbi engu-0.060″ ewugqinsi engu-304 ene-bend eyodwa kanye no-2.0 no-1.5″ yobukhulu bangaphandle, kanye no-0.75″.Enqenqemeni.Futhi, awuzange ufake ulwazi mayelana ne-engeli yokugoba nangaphakathi bend radius, kodwa ukuze kube lula ngibala i-engeli engu-9 nge-engeli yomoya.4 ngenze i-engeli yomoya engu-27. Lokhu kukunikeza irediyasi egobayo engu-0.099 inch, ebalwe kusetshenziswa umthetho ongu-20%. (Ukuze uthole okwengeziwe ngomthetho ka-20%, ungabheka “Indlela Yokubikezela Ngokunembile I-Inner Bend Radius Yokwakheka komoya” ngokuthayipha isihloko ebhokisini lokusesha le-thefabricator.com.)
Uma ingamayintshi angu-0.062.I-punch radius igoba okokusebenza ngamayintshi angaphezu kuka-0.472. Ukuvula i-Die, ufinyelela amayintshi angu-0.099. Untanta ngaphakathi kwendawo egobileyo, i-BA yakho kufanele ibe amayintshi angu-0.141, ukubuyisela emuva kwangaphandle kufanele kube amayintshi angu-0.125, futhi ukuncishiswa kwe-bend kube ngamayintshi angu-0.BD10 kufanele kube ngu-0.BD10 2.0 amayintshi.(Ungathola amafomula e-BA ne-BD kukholamu yami yangaphambilini, okuhlanganisa “Okuyisisekelo Sokusebenzisa Imisebenzi Yokugoba.”)
Okulandelayo, udinga ukubala ukuthi yini okufanele udonse ku-hem.Ngaphansi kwezimo eziphelele, into edonswayo yamahemu ayisicaba noma avaliwe (izinto ezingaphansi kwamasentimitha angu-0.080 ubukhulu) ingu-43% wogqinsi lwempahla.Kulokhu, inani kufanele libe ngamasentimitha angu-0.0258.Usebenzisa lolu lwazi, kufanele ukwazi ukwenza indiza isibalo esingenalutho:
0.017 amayintshi.Umehluko phakathi kwevelu yakho eyisicaba engenalutho engu-4.132 amayintshi kanye neyami engu-4.1145 amayintshi ingachazwa kalula ngokuthi i-hemming incike kakhulu ku-opharetha.Ngiqonde ukuthini?Hhayi-ke, uma u-opharetha eshaya kakhulu ingxenye eyisicaba yenqubo yokugoba, uzothola i-flange ende.
Q: Sinesicelo sokugoba lapho sakha khona amashidi ensimbi ahlukahlukene, kusukela ku-20-ga.I-Stainless kuya ku-10-ga.Impahla ehlanganiswe ngaphambili.Sinebhuleki lokucindezela elinokulungiswa kwethuluzi elizenzakalelayo, i-V-die eguquguqukayo phansi kanye ne-punch ehlukanisiwe yokuzibeka endaweni phezulu.Ngeshwa, senze iphutha futhi sa-oda i-punch6 ye-tip3us″.
Sisebenzela ukuthola ubude bethu be-flange buhambisane engxenyeni yokuqala.Kuphakanyiswe ukuthi isofthiwe yethu ye-CAD isebenzisa ukubala okungalungile, kodwa inkampani yethu yesofthiwe yabona inkinga futhi yathi silungile.Ingabe kuzoba isofthiwe yomshini wokugoba?Noma ingabe sicabanga ngokweqile?Ingabe ukulungiswa kwe-BA evamile noma singathola i-punch entsha nge-0.032" noma yiluphi ulwazi olungaba usizo olungasiza?
A: Ngizobhekana nokuphawula kwakho mayelana nokuthenga i-punch radius engalungile kuqala. Uma kubhekwa uhlobo lomshini onalo, ngicabanga ukuthi wenza umoya. Lokhu kungenza ngibuze imibuzo eminingana. Okokuqala, lapho uthumela umsebenzi esitolo, uyamtshela yini u-opharetha ukuthi iyiphi isikhunta idizayini yokuvula ingxenye eyakhiwe? Kwenza umehluko omkhulu.
Uma wenza ingxenye yomoya, irediyasi yokugcina yangaphakathi yakheka njengephesenti lokuvuleka kwesikhunta.Lona umthetho we-20% (bona umbuzo wokuqala ukuze uthole ulwazi olwengeziwe).I-fae opening ithinta i-radius yokugoba, yona ethinta i-BA ne-BD.Ngakho-ke uma ukubala kwakho kufaka phakathi irediyasi ehlukile efinyelelekayo yokuvula ukufa kunaleyo umqhubi ayisebenzisayo emshinini, unenkinga.
Ake sithi umshini usebenzisa ububanzi bokufa obuhlukile kunalokho obekuhleliwe.Kulokhu, umshini uzofinyelela irediyasi yokugoba ehlukile yangaphakathi kunokuhleliwe, ukushintsha i-BA ne-BD, futhi ekugcineni ubukhulu bengxenye obukhiwe.
Lokhu kungiletha emazwaneni akho mayelana ne-punch radius engalungile.0.063″ ngaphandle uma uzama ukuthola irediyasi yokugoba ehlukile noma encane yangaphakathi.Irediyasi kufanele isebenze kahle, yingakho.
Linganisa irediyasi yokugoba yangaphakathi etholiwe futhi uqiniseke ukuthi ifana nerediyasi yokugoba engaphakathi ebaliwe.Ingabe irediyasi yakho ye-punch ayilungile ngempela?Kuncike kulokho ofuna ukukuzuza.I-punch radius kufanele ilingane noma ibe ngaphansi kwerediyasi yokugoba entantayo yangaphakathi. ye-BA kanye ne-BD.
Ngakolunye uhlangothi, awufuni ukusebenzisa i-punch radius encane kakhulu, engalola ukugoba futhi ibangele ezinye izinkinga eziningi. (Ukuze uthole okwengeziwe ngalokhu, bheka “Indlela Yokugwema Ukuphenduka Okubukhali.”)
Ngaphandle kwalokhu okubili okweqisayo, i-punch esesimweni somoya ayilutho ngaphandle kweyunithi yokuphusha futhi ayithinti i-BD ne-BA. Futhi, irediyasi yokugoba iboniswa njengephesenti lokuvuleka kwefasi, kubalwa kusetshenziswa umthetho we-20%. Futhi, qiniseka ukuthi usebenzisa imigomo namanani we-BA ne-BD ngendlela efanele, njengoba kuboniswe kuMfanekiso 1.
Umbuzo: Ngizama ukubala amandla asemaceleni aphezulu ethuluzi le-hemming langokwezifiso ukuze ngiqinisekise ukuthi o-opharetha bethu baphephile ngesikhathi senqubo ye-hemming.Ingabe unawo amathiphu okungisiza ngithole lokhu?
Impendulo: I-Lateral force noma i-lateral thrust inzima ukulinganisa nokubala ukucaba umphetho kwibhuleki lokucindezela futhi ezimweni eziningi akudingekile.Ingozi yangempela ukulayisha ngokweqile ibhuleki lokucindezela futhi kucekele phansi i-punch nombhede womshini.Inqama nombhede kugingqike okubangela ukuba ngamunye agobe unomphela.
Umfanekiso 2. Ama-thrust plate kusethi yama-dies aphansi aqinisekisa ukuthi amathuluzi aphezulu naphansi awahambi ngendlela ephambene.
Ibhuleki lokucindezela ngokuvamile liyachezuka ngaphansi komthwalo futhi libuyela endaweni yalo yasekuqaleni eyisicaba lapho umthwalo ususiwe. Kodwa ukweqa umkhawulo womthwalo wamabhuleki kungagobisa izingxenye zomshini kuze kube lapho zingasabuyeli endaweni eyisicaba. Lokhu kungalimaza unomphela ibhuleki lokucindezela. Ngakho-ke, qiniseka ukuthi ucabangela ukusebenza kwakho kwe-hemming ekubalweni kwamathoni.(Ukuze uthole okwengeziwe ngalokhu, ungacindezela izinsika ze-4).
Uma i-flange okufanele yenziwe isicaba iyinde ngokwanele ukuba isicaba, ukusunduza ohlangothini kufanele kube kuncane. Nokho, uma uthola ukuthi i-thrust eseceleni ibonakala ingaphezu kwamandla futhi ufuna ukukhawulela ukunyakaza nokusonteka kwe-mod, ungakwazi ukwengeza ama-thrust plate ku-mod. futhi amathuluzi angaphansi awahambi ngendlela ephambene (bheka Umfanekiso 2).
Njengoba ngishilo ekuqaleni kwale kholamu, miningi kakhulu imibuzo kanye nesikhathi esincane kakhulu sokuyiphendula yonke. Ngiyabonga ngesineke sakho uma usanda kungithumelela imibuzo.
Kunoma yikuphi, vumela imibuzo iqhubeke ivela.Ngizoyiphendula ngokushesha ngangokunokwenzeka.Kuze kube yileso sikhathi, ngithemba ukuthi izimpendulo lapha zisiza labo ababuza umbuzo nabanye ababhekene nezinkinga ezifanayo.
Yembula izimfihlo zokusebenzisa ibhuleki lomshini kule workshop yezinsuku ezimbili zika-Agasti 8-9 nomfundisi uSteve Benson ukuze akufundise ithiyori nezisekelo zezibalo ngemuva komshini wakho.
