Bengilokhu ngisebenza ngokusalela emuva kwezinkinga zabafundi - ngisenawo amakholomu ambalwa okufanele ngiwabhale ngaphambi kokuba ngiphinde ngibambe.Uma ungithumele umbuzo futhi angizange ngiwuphendule, ngicela ulinde, umbuzo wakho ungase ube olandelayo.Sinalokho engqondweni, ake siphendule umbuzo.
Q: Sizama ukukhetha ithuluzi elizohlinzeka ngamayintshi angu-0.09.irediyasi.Ngalahla inqwaba yezingxenye ukuze ngihlolwe;inhloso yami ukusebenzisa isitembu esifanayo kuzo zonke izinto zethu.Ungakwazi ukungifundisa indlela yokusebenzisa u-0.09″ ukubikezela irediyasi yokugoba?irediyo yokuhamba?
A: Uma wenza umoya, ungakwazi ukubikezela irediyasi yokugoba ngokuphindaphinda ukuvulwa kwefa ngephesenti ngokusekelwe ohlotsheni lwento.Uhlobo lwento ngayinye lunobubanzi bephesenti.
Ukuthola amaphesenti wezinye izinto zokwakha, ungaqhathanisa amandla awo okuqina namandla angu-60,000 we-psi wezinto zethu eziyisethenjwa (insimbi egoqelwe ngekhabhoni ebandayo ephansi).Isibonelo, uma impahla yakho entsha inamandla we-tensile angu-120,000 psi, ungalinganisela ukuthi iphesenti lizoba kabili kunesisekelo, noma cishe u-32%.
Ake siqale ngezinto zethu eziyisethenjwa, insimbi egoqekayo enekhabhoni ebandayo enamandla angu-60,000 psi.Irediyasi yokwakheka komoya yangaphakathi yalesi sici iphakathi kuka-15% no-17% wokuvuleka kwefa, ngakho-ke ngokuvamile siqala ngevelu yokusebenza engu-16%.Lobu bubanzi bubangelwa ukuhluka kwazo okungokwemvelo kokubalulekile, ukujiya, ukuqina, amandla aqinile, namandla esivuno.Zonke lezi zakhiwo ezibonakalayo zinezinhlobonhlobo zokubekezelelana, ngakho-ke akunakwenzeka ukuthola amaphesenti aqondile.Azikho izingxenye ezimbili zezinto ezifanayo.
Unakho konke lokhu engqondweni, uqala nge-median engu-16% noma u-0.16 bese uphindaphinda lokho ngokuqina kwento.Ngakho-ke, uma wenza i-A36 impahla enkulu kuno-0.551 amayintshi.Uma i-die ivuliwe, i-radius yakho yangaphakathi yokugoba kufanele ibe ngu-0.088″ (0.551 × 0.16 = 0.088).Uyobe ususebenzisa u-0.088 njengevelu elilindelekile lendawo egobile engaphakathi oyisebenzisayo ekuvumeleni ukugoba nokubala kokukhipha okugobayo.
Uma uhlala uthola impahla evela kumhlinzeki ofanayo, uzokwazi ukuthola iphesenti elingakusondeza ku-radius egobile yangaphakathi oyitholayo.Uma impahla yakho ivela kubahlinzeki abahlukahlukene abahlukahlukene, kungcono ukushiya inani elibaliwe le-median, njengoba izakhiwo zezinto ezibonakalayo zingahluka kakhulu.
Uma ufuna ukuthola imbobo yokufa ezonikeza indawo ethile engaphakathi yokugoba, ungaguqula ifomula:
Kusuka lapha ungakhetha imbobo yokufa etholakalayo eseduze kakhulu.Qaphela ukuthi lokhu kuthatha ukuthi i-radius yangaphakathi yokugoba ofuna ukuyifinyelela ifana nogqinsi lwento oyenza emoyeni.Ukuze uthole imiphumela ehamba phambili, zama ukukhetha ukuvuleka okufayo okune-radius egobile yangaphakathi eseduze noma elingana nogqinsi lwento.
Uma ucabangela zonke lezi zici, imbobo yokufa oyikhethayo izokunikeza irediyasi yangaphakathi.Futhi qiniseka ukuthi i-punch radius ayeqi irediyasi yokugoba yomoya ezintweni.
Khumbula ukuthi ayikho indlela ephelele yokubikezela i-bend radii yangaphakathi uma kubhekwa zonke izinto eziguquguqukayo.Ukusebenzisa lawa maphesenti obubanzi be-chip kuwumthetho onembe kakhudlwana.Nokho, kungase kudingeke ukushintshanisa imilayezo ngenani lephesenti.
Q: Muva nje ngithole imibuzo embalwa mayelana nokuthi kungenzeka yini ukwenza uzibuthe ithuluzi lokugoba.Yize singakaboni ukuthi lokhu kwenzeka ngethuluzi lethu, nginelukuluku lokwazi ngezinga lenkinga.Ngiyabona ukuthi uma isikhunta sinozibuthe kakhulu, okungenalutho "kungakwazi ukunamathela" esikhunjeni futhi kungenzi ngokuqhubekayo ukusuka kwesinye isiqeshana kuya kwesinye.Ngaphandle kwalokho, ingabe zikhona ezinye izinkathazo?
Impendulo: Abakaki noma abakaki abasekela i-die noma abasebenzisana nesisekelo samabhuleki avamile abanziwe zibuthe.Lokhu akusho ukuthi umcamelo wokuhlobisa awukwazi ukwenziwa uzibuthe.Lokhu ngeke kwenzeke.
Nokho, kunezinkulungwane zezingcezu ezincane zensimbi ezingaba uzibuthe, noma ngabe ucezu lokhuni enqubweni yokugxiviza noma i-radius gauge.Ibucayi kangakanani le nkinga?ngempela sina.Kungani?Uma lesi siqephu esincane sezinto singabanjwanga ngesikhathi, singamba endaweni yokusebenza yombhede, senze indawo ebuthakathaka.Uma ingxenye enozibuthe iwugqinsi ngokwanele noma inkulu ngokwanele, ingabangela okokusebenza kombhede ukuthi kuphakame emaphethelweni okufaka, kuqhubeke kubangele ukuthi i-base plate ihlale ngokungalingani noma ngokulinganayo, okuzophinde kuthinte ikhwalithi yengxenye ekhiqizwayo.
UMB: Esihlokweni sakho Ukuthi Amajika Omoya Abukhali Kanjani, usho ifomula: I-Punch Tonnage = Indawo Yezicathulo x Ukuqina Kwezinto x 25 x Isici Sezinto.Uvelaphi u-25 kule zibalo?
A: Le fomula ithathwe ku-Wilson Tool futhi isetshenziselwa ukubala i-punch tonnage futhi ayihlanganise lutho nokwakheka;Ngiyiguqule ukuze nginqume ngokwamandla lapho ijika likhuphuka khona.Inani lika-25 kufomula libhekisela kumandla okukhiqiza wento esetshenziswa ekwakheni ifomula.Ngendlela, le nto ayisakhiqizwa, kodwa iseduze nensimbi ye-A36.
Yiqiniso, kudingeka okwengeziwe ukuze ubale ngokunembile iphuzu lokugoba nomugqa wokugoba wethiphu ye-punch.Ubude bokugoba, indawo esibonakalayo phakathi kwekhala le-punch kanye nezinto ezibonakalayo, ngisho nobubanzi bokufa kudlala indima ebalulekile.Kuye ngesimo, irediyasi ye-punch efanayo yento efanayo ingakhiqiza ukugoba okubukhali nokugoba okuphelele (okungukuthi, ukugoba nge-radius yangaphakathi ebikezelwe futhi kungabikho ama-crease emugqeni ogoqayo).Uzothola isibali esihle kakhulu sokugoba kuwebhusayithi yami esithatha zonke lezi ziguquguqukayo zicabangele.
Umbuzo: Ingabe ikhona ifomula yokususa ukugoba kusukela kukhawunta emuva?Kwesinye isikhathi ochwepheshe bethu bamabhuleki omshini basebenzisa izimbobo ezincane ze-V esingazange sizibale ohlelweni lwaphansi.Sisebenzisa izimali ezibanjwayo ezijwayelekile.
Impendulo: yebo futhi cha.Ake ngichaze.Uma igoba noma igxiviza phansi, uma ububanzi besikhunta bufana nobukhulu bempahla yokubumba, ibhande akufanele lishintshe kakhulu.
Uma wenza umoya, i-radius yangaphakathi yokugoba inqunywa imbobo yokufa futhi ukusuka lapho uthatha irediyasi etholwe ku-die bese ubala ukukhishwa kwe-bend.Ungathola izihloko zami eziningi ngale ndaba ku-TheFabricator.com;bheka u-"Benson" futhi uzobathola.
Ukuze ukusebenza komoya kusebenze, abasebenzi bakho bonjiniyela bazodinga ukudizayina i-slab besebenzisa ukugoba ngokususa okusekelwe endaweni ezungezile entantayo eyenziwe yifa (njengoba kuchazwe kokuthi “Bend Inside Radius Prediction” ekuqaleni kwalesi sihloko).Uma u-opharetha wakho esebenzisa isikhunta esifanayo nengxenye yakhelwe ukuba yakhe, ingxenye yokugcina kufanele iyifanele imali.
Nakhu okungajwayelekile kakhulu - umlingo omncane weshabhu ovela kumfundi oshisekayo ophawula kukholamu engiyibhale ngoSepthemba 2021 "Amasu Okubhuleka E-T6 Aluminium".
Impendulo yomfundi: Okokuqala, ubhale izindatshana ezinhle kakhulu ekusebenzeni kwensimbi.Ngiyakubonga ngabo.Mayelana nokukhishwa okuchaze kukholamu yakho kaSepthemba 2021, ngicabange ukuthi ngizokwabelana ngemicabango evela kokuhlangenwe nakho kwami.
Lapho ngiqala ukubona iqhinga lokudonsa eminyakeni eminingi edlule, ngatshelwa ukuthi ngisebenzise ithoshi le-oxy-acetylene, ngithungele igesi ye-acetylene kuphela, futhi ngipende imigqa yesikhunta ngomsizi omnyama ophuma kugesi ye-acetylene eshile.Okudingayo umugqa onsundu kakhulu noma omnyama kancane.
Bese uvula umoya-mpilo bese ushisisa ucingo ukusuka kolunye uhlangothi lwengxenye futhi ukusuka ebangeni elifanele kuze kube ucingo olunombala osanda kulunamathisela luqala ukufiphala bese lunyamalala ngokuphelele.Lokhu kubonakala kuyizinga lokushisa elilungile lokudonsa i-aluminium ngokwanele ukunikeza umumo ongu-90 degree ngaphandle kwezinkinga zokuqhekeka.Awudingi ukubumba ingxenye ngenkathi kushisa.Ungayiyeka iphole futhi isazokhishwa.Ngikhumbula ngenza lokhu ku-1/8″ ishidi elingu-6061-T6 eliwugqinsi.
Bengizibandakanye ngokujulile ekwenziweni kwensimbi ye-precision sheet iminyaka engaphezu kwengu-47 futhi bengilokhu nginekhono lokufihla.Kodwa ngemva kweminyaka eminingi kangaka, angisayifaki.Ngiyazi engikwenzayo!Noma mhlawumbe ngingcono ngokuzifihla.Kunoma ikuphi, ngakwazi ukwenza umsebenzi ngendlela eyonga kakhulu ngamafrills amancane.
Ngiyazi into noma ezimbili mayelana nokukhiqizwa kweshidi lensimbi, kodwa ngiyavuma ukuthi anginalwazi nhlobo.Ngizizwa ngihloniphekile ukwabelana nawe ngolwazi engiluqongelele empilweni yami.
