Kudala ndisebenza ngokusilela kwimiba yabafundi – ndisenezikholamu ezimbalwa ekufuneka ndizibhale phambi kokuba ndiphinde ndibambe.Ukuba undithumele umbuzo kwaye andawuphendula, ndicela ulinde, umbuzo wakho ungalandela.Unaloo nto engqondweni, masiphendule umbuzo.
Q: Sizama ukukhetha isixhobo esiza kubonelela nge-0.09 intshi.iradiyasi.Ndalahla iqela lamalungu ukuze ndivavanywe;Injongo yam kukusebenzisa isitampu esifanayo kuzo zonke izixhobo zethu.Ungandifundisa ukusebenzisa i-0.09″ ukuqikelela iradiyasi egobileyo?irediyasi yokuhamba?
A: Ukuba ubumba umoya, unokuqikelela irediyasi yokugoba ngokuphindaphinda ukuvulwa kwefa ngepesenti ngokusekelwe kuhlobo lwezinto.Uhlobo ngalunye lwemathiriyeli lunoluhlu lwepesenti.
Ukufumana iipesenteji zezinye izinto, unokuthelekisa amandla abo okuqina kunye ne-60,000 psi yamandla okuqina kwezinto zethu zokukhangela (intsimbi ephantsi yekhabhoni ebandayo eqengqiwe).Umzekelo, ukuba izinto zakho ezintsha zinamandla e-tensile ye-120,000 psi, unokuqikelela ukuba ipesenti iya kuba kabini isiseko, okanye malunga ne-32%.
Masiqale ngemathiriyeli yethu yereferensi, intsimbi ephantsi yekhabhoni ebandayo eqengqelekayo eqinileyo ye60,000 psi.I-radius yokwakheka komoya yangaphakathi yale nto iphakathi kwe-15% kunye ne-17% yokuvula ukufa, ngoko ke ngokuqhelekileyo siqala ngexabiso elisebenzayo le-16%.Olu luhlu lubangelwa kukwahluka kwemvelo kwizinto eziphathekayo, ubukhulu, ubunzima, amandla okuqina, kunye namandla emveliso.Zonke ezi zixhobo eziphathekayo zinoluhlu lokunyamezela, ngoko akunakwenzeka ukufumana ipesenti echanekileyo.Akukho ziqwenga zibini zemathiriyeli ezifanayo.
Unayo yonke le nto engqondweni, uqala nge-median ye-16% okanye i-0.16 kwaye uphindaphinde oko ngobunzima bezinto eziphathekayo.Ngoko ke, ukuba wenza i-A36 imathiriyeli enkulu kune-intshi ye-0.551.Ngokuvula ukufa, iradiyasi yakho yangaphakathi yokugoba kufuneka ibe malunga ne-0.088 ″ (0.551 × 0.16 = 0.088).Emva koko uya kusebenzisa i-0.088 njengexabiso elilindelekileyo kwi-radius ye-bend yangaphakathi oyisebenzisayo kwisibonelelo sokugoba kunye nokubalwa kokuthabatha ukugoba.
Ukuba uhlala ufumana izinto ezivela kumboneleli ofanayo, uya kukwazi ukufumana ipesenti enokukusondeza kwi-radius ye-bend yangaphakathi oyifumanayo.Ukuba izinto zakho zivela kubaboneleli abaninzi abahlukeneyo, kungcono ukushiya ixabiso eliphakathi elibaliweyo, njengoko iipropati eziphathekayo zinokuhluka kakhulu.
Ukuba ufuna ukufumana umngxuma wokufa oza kunika iradiyasi egobileyo ngaphakathi, ungaguqula ifomula:
Ukusuka apha ungakhetha owona mngxunya wokufa ukufutshane.Qaphela ukuba oku kuthatha ukuba iradiyasi yangaphakathi yegophe ofuna ukuyiphumeza ihambelana nobukhulu bezinto ozenzayo emoyeni.Ukuze ufumane iziphumo ezingcono, zama ukukhetha indawo yokufa ene-radius ye-bend yangaphakathi ekufutshane okanye elingana nobukhulu bezinto.
Xa uthathela ingqalelo yonke le miba, umngxuma wokufa owukhethayo uya kukunika iradiyasi yangaphakathi.Kwakhona qiniseka ukuba i-radius ye-punch ayidluli i-radius yokugoba yomoya kwizinto eziphathekayo.
Gcina ukhumbule ukuba akukho ndlela igqibeleleyo yokuqikelela i-radii ye-bend yangaphakathi enikwe zonke izinto eziphathekayo.Ukusebenzisa ezi pesenti zobubanzi betshiphu ngumgaqo ochanekileyo wobhontsi.Nangona kunjalo, kunokuba yimfuneko ukutshintshisa imiyalezo ngexabiso lepesenti.
Q: Kutshanje ndifumene imibuzo emininzi malunga nokuba nokwenzeka kokwenza imagnethi isixhobo sokugoba.Ngelixa singayiqaphelanga le nto yenzekayo ngesixhobo sethu, ndinomdla wokwazi ubungakanani bengxaki.Ndiyabona ukuba isikhunta sinomagnetic kakhulu, into engenanto inokuthi "inamathele" kwimbumba kwaye ingenzi ngokuqhubekayo ukusuka kwisiqwenga esinye ukuya kwesinye.Ngaphandle koko, ngaba zikho ezinye izinto ezixhalabisayo?
Impendulo: Izibiyeli okanye izibiyeli ezixhasa ukufa okanye ukusebenzisana nesiseko sebrake yokucofa aziqhelekanga ukuba zenziwe ngemagnethi.Oku akuthethi ukuba umqamelo wokuhombisa awukwazi ukwenziwa ngemagnethi.Oku akunakwenzeka ukuba kwenzeke.
Nangona kunjalo, kukho amawaka amaqhekeza amancinci entsimbi anokuthi abe ngumagnet, nokuba liqhekeza lenkuni kwinkqubo yokunyathela okanye i-radius gauge.Inzulu kangakanani le ngxaki?ngokunzulu.Ngoba?Ukuba le nxalenye encinci yezinto eziphathekayo ayibanjwanga ngexesha, inokumba kwindawo yomsebenzi webhedi, idale indawo ebuthathaka.Ukuba indawo enemagnethi ingqindilili ngokwaneleyo okanye inkulu ngokwaneleyo, inokubangela ukuba izinto zebhedi ziphakame zijikeleze imiphetho yokufaka, kubangele ukuba iplate yesiseko ihlale ngokungafaniyo okanye ngokulinganayo, nto leyo eya kuthi ichaphazele umgangatho wenxalenye eveliswayo.
Umbuzo: Kwinqaku lakho Indlela i-Air Curves ebukhali ngayo, ukhankanye ifomyula: I-Punch Tonnage = Indawo yesihlangu x Ubukhulu bezinto x 25 x i-Material Factor.Uvela phi u-25 kule nxaki?
A: Le fomula ithathwa kwi-Wilson Tool kwaye isetyenziselwa ukubala i-punch tonnage kwaye ayinanto yokwenza;Ndiyilungelelanise ukuze ndibone ukuba igophe liya linyukela phi na.Ixabiso le-25 kwifomula libhekiselele kumandla okuvelisa izinto ezisetyenziselwa ukuphuhlisa ifomula.Ngendlela, le nto ayisayi kuveliswa, kodwa isondele kwintsimbi ye-A36.
Ngokuqinisekileyo, kuninzi okufunekayo ukubala ngokuchanekileyo indawo yokugoba kunye nomgca wokugoba we-punch tip.Ubude be-bend, indawo yokujongana phakathi kwempumlo yepunch kunye nezinto eziphathekayo, kunye nobubanzi bokufa budlala indima ebalulekileyo.Ngokuxhomekeke kwimeko, i-radius ye-punch efanayo yezinto ezifanayo inokuvelisa ukugoba okubukhali kunye nokugoba okugqibeleleyo (oko kukuthi, ukugoba kunye ne-radius yangaphakathi eqikelelweyo kwaye akukho ngqungquthela kumgca wokugoqa).Uya kufumana i-calculator ebukhali ebukhali kwiwebhusayithi yam ethatha zonke ezi ziguquguqukayo.
Umbuzo: Ngaba kukho ifomula yokususa ukugoba ukusuka kwikhawuntara ngasemva?Ngamanye amaxesha amagcisa ethu e-brake technician asebenzisa i-V-mingxuma emincinci esingakhange siyiphendule kwiplani yomgangatho.Sisebenzisa ukutsalwa kokugoba okusemgangathweni.
Impendulo: ewe kwaye hayi.Makhe ndikucacisele.Ukuba iyagoba okanye i-stamping ephantsi, ukuba ububanzi besikhunta buhambelana nobukhulu bezinto zokubumba, i-buckle akufanele itshintshe kakhulu.
Ukuba wenza umoya, i-radius yangaphakathi ye-bend inqunywe ngumngxuma wokufa kwaye ukusuka apho uthatha i-radius efunyenwe kwi-die kwaye ubale ukutsalwa kwe-bend.Ungafumana amanqaku am amaninzi kulo mbandela kwiTheFabricator.com;khangela "Benson" kwaye uya kubafumana.
Ukuze i-airforming isebenze, abasebenzi bakho bobunjineli baya kufuna ukuyila i-slab ngokusebenzisa ukugoba ukugoba ngokusekelwe kwiradiyasi edadayo eyenziwe yi-die (njengoko kuchazwe kwi-"Bend Inside Radius Prediction" ekuqaleni kweli nqaku).Ukuba umqhubi wakho usebenzisa umngundo ofanayo nenxalenye eyenzelwe ukwenza, inxalenye yokugqibela kufuneka ixabise imali.
Nantsi into engaqhelekanga kakhulu-umlingo omncinci wocweyo ovela kumfundi okhutheleyo ogqabaza kwikholamu endiyibhale ngoSeptemba ka-2021 “Amaqhinga eBraking for T6 Aluminium”.
Impendulo yomfundi: Okokuqala, ubhale amanqaku agqwesileyo kwiphepha lesinyithi elisebenza.Ndiyabulela ngabo.Ngokumalunga nokufakwa kwakho okuchazwe kwikholamu yakho kaSeptemba ka-2021, ndicinge ukuba ndingabelana ngeengcinga kumava am.
Ukuqala kwam ukubona iqhinga lokutsala iminyaka emininzi eyadlulayo, kwathiwa mandisebenzise itotshi ye-oxy-acetylene, ndilumeke kuphela igesi ye-acetylene, kwaye ndipeyinte imigca yokungunda ngomsizi omnyama ophuma kwirhasi ye-acetylene etshisiweyo.Ekuphela kwento oyifunayo ngumgca omnyama kakhulu okanye omnyama kancinci.
Emva koko vula ioksijini kwaye ufudumeze ucingo ukusuka kwelinye icala lenxalenye kwaye ukusuka kumgama ofanelekileyo de ucingo olunombala osanda kuluncamathisela luqala ukucima kwaye lunyamalale ngokupheleleyo.Oku kubonakala ngathi liqondo lobushushu elilungileyo lokucoca i-aluminiyam ngokwaneleyo ukubonelela ngemilo ye-90 degree ngaphandle kwemiba yokuqhekeka.Awudingi ukubumba indawo ngelixa liseshushu.Ungayiyeka iphole kwaye iya kuhlala ivaliwe.Ndikhumbula ndisenza oku kwi-1/8 ″ engqindilili ye-6061-T6 sheet.
Ndizibandakanye nzulu kwimveliso yentsimbi echanekileyo ngaphezulu kweminyaka engama-47 kwaye bendisoloko ndinobuchule bokufihla.Kodwa emva kweminyaka emininzi kangaka, andisayifaki.Ndiyayazi into endiyenzayo!Okanye mhlawumbi ndingcono ngokuzifihla.Kuyo nayiphi na imeko, ndakwazi ukwenza umsebenzi wenziwe ngeyona ndlela inoqoqosho kakhulu ngefrills encinci.
Ndiyazi into okanye ezimbini malunga nokuveliswa kwesinyithi, kodwa ndiyavuma ukuba andinalwazi nangayiphi na indlela.Ndiziva ndinelunda ukwabelana nani ngolwazi endiluqokelele ebomini bam.
