MAGNABEND IMBALI YOPHUHLISO NOKWENZA
IGenesis yoMbono:
Emva phayaa ngowe-1974 kwafuneka ndenze iibhokisi zezakhiwo ze-elektroniki.Ukwenza oku ndizenzele ifolda ye-sheetmetal ekrwada kakhulu kwiziqwenga ezimbalwa zentsimbi ezihonjiswe kunye zaza zabanjwa kwi-vice.Ukuthetha okuncinci bekungelula kakhulu ukuyisebenzisa kwaye ayiguquguquki kakhulu.Kungekudala ndagqiba ekubeni lixesha lokuba ndenze into engcono.
Ndiye ndacinga ngendlela yokwenza ifolda 'efanelekileyo'.Enye into eyayindikhathaza kukuba isakhiwo sokugoba kwakufuneka sibotshelelwe emva kwisiseko somatshini mhlawumbi ekupheleni okanye ngasemva kwaye oku kwakuza kuphazamisa ezinye zezinto endifuna ukuzenza.Ngoko ndenza ukholo lwam kwaye ndathi ... Kulungile, masingabophelelani isakhiwo sokubambelela kwisiseko, ndingayenza njani loo nto?
Ngaba yayikhona indlela yokuluqhawula olo nxibelelwano?
Ngaba unokubambelela entweni ngaphandle kokuncamathela nto kuyo?
Oko kwakubonakala ngathi ngumbuzo budenge ukuwubuza kodwa kanye xa ndiwubeke lo mbuzo ngaloo ndlela ndeza nempendulo endinokuba nayo: -
Uyakwazi ukuphembelela izinto ngaphandle koqhagamshelo ngokwasemzimbeni kubo ... nge FIELD!
Ndandizazi iindawo zombane*, imimandla yomxhuzulane*, nemagnethi*.Kodwa ngaba iya kwenzeka?Ngaba iya kusebenza ngokwenene?
(* Njengecala, kubangel’ umdla ukuqaphela ukuba inzululwazi yale mihla iseza kucacisa ngokupheleleyo ukuba ngokwenene “ukunyanzeliswa komgama” kusebenza njani na).
Okwenzeka emva koko kuseyinkumbulo ecacileyo.
Ndandikwi workshop yam yasekhaya kwabe kusemva kwasezinzulwini zobusuku kwanexesha lokulala, kodwa andizange ndikwazi ukumelana nesilingo sokuzama lombono mtsha.
Kungekudala ndafumana umazibuthe wesihlangu sehashe kunye neqhekeza leshim brass.Ndafaka ishim brass phakathi kwemagnethi kunye 'nomgcini' wayo ndaza ndagoba ubhedu ngomnwe wam!
Eureka!Isebenzile.Ubhedu lwaluyi-0.09mm kuphela ubukhulu kodwa umgaqo wasekwa!
(Ifoto esekhohlo lulwakhiwo ngokutsha lomfuniselo wokuqala kodwa usebenzisa izinto ezifanayo).
Ndandichulumancile kuba ndaqonda, zisuka nje, ukuba uluvo lunokwenziwa ukuba lusebenze ngendlela ebonakalayo luza kubonisa ingcamango entsha kwindlela yokwenza i-sheetmetal.
Ngosuku olulandelayo ndaxelela ugxa wam emsebenzini, uTony Grainger, ngeembono zam.Naye wayenemincili kwaye wandizobela uyilo olunokwenzeka lwemagnethi yombane kum.Wenza nezibalo ezithile malunga nokuba loluphi uhlobo lwamandla anokufumaneka kwi-electromagnetic.UTony wayengoyena mntu ukrelekrele endandimazi kwaye ndandinethamsanqa lokuba naye njengomntu endisebenza naye kwaye ndikwazi ukufikelela kubuchule bakhe.
Ewe, ekuqaleni bekubonakala ngathi umbono unokusebenza kuphela kwiigeyiji ezincinci ze-sheetmetal kodwa ibithembisa ngokwaneleyo ukundikhuthaza ukuba ndiqhubeke.
Uphuhliso lwakwangoko:
Kwiintsuku ezimbalwa ezalandelayo ndafumana iingceba zentsimbi, ucingo lobhedu, kunye nesixhobo sokulungisa ndaza ndakha ifolda yam yokuqala ye-electro-magnetic!Ndisenayo kwindawo yam yokusebenzela:
Inxalenye ye-electro-magnetic yalo matshini yeyoqobo yoqobo.
(Ipali yangaphambili kunye nomqadi ogobayo oboniswe apha yayizinguqulelo kamva).
Nangona kunokuba krwada lo matshini wasebenza!
Njengoko bekucingelwa kumzuzu wam woqobo we-eureka, eneneni ibar ebambezelayo bekunganyanzelekanga ukuba incanyathiselwe kwisiseko somatshini eziphelweni, ngasemva, okanye naphi na.Ngaloo ndlela umatshini wawuvuleke ngokupheleleyo kwaye uvule umqala.
Kodwa inkalo evulekileyo inokuqondwa kuphela ukuba iihenjisi zomqadi ogobayo nazo aziqhelekanga.
Kwiinyanga ezizayo ndisebenze kuhlobo lwehinge enesiqingatha endiyibize ngokuba 'yihinge yekomityi', ndakhe umatshini osebenza ngcono (uMarko II), ndafaka iNgcaciso yePatent yexeshana kwiOfisi yePatent yase-Australia kwaye ndavela kwakhona. inkqubo kamabonakude ka-ABC ebizwa ngokuba yi "The Inventors".Into endiyiyileyo yakhethwa njengophumeleleyo kuloo veki kwaye kamva yaya kunyulwa njengomnye wabaphumeleleyo kuloo nyaka (ngo-1975).
Ngasekhohlo nguMark II bender njengoko kubonisiwe eSydney kulandela ukubonakala kokugqibela kweThe Inventors.
Isebenzise inguqulelo ephuhliswe ngakumbi 'yehinge yekomityi' njengoko kubonisiwe ngezantsi:
Ngexesha lika-1975 ndadibana noGeoff Fenton kwintlanganiso ye-Inventors Association eHobart (3 Agasti 1975).UGeoff wayenomdla kakhulu kuyilo lwe "Magnabend" kwaye wabuyela endaweni yam emva kwentlanganiso ukuze ayijonge ngakumbi.Oku yayiza kuba sisiqalo sobuhlobo obuhlala buhleli noGeoff kwaye kamva nentsebenziswano yezoshishino.
UGeoff wayenesidanga sobuNjineli kunye nomyili okrelekrele ngokwakhe.Wakubona ngokukhawuleza ukubaluleka kokuba noyilo lwehenjisi oluya kuvumela umatshini ukuba aqonde amandla awo apheleleyo.
'Ihinge yekomityi' yam isebenzile kodwa ndineengxaki ezinzulu kwii-engile ze-beam ngaphezulu kwe-90 degrees.
UGeoff waba nomdla kakhulu kwiihenjisi ezingenaziko.Olu didi lwehinge lunokubonelela ngokujikeleza kwindawo enenyani enokuba ngaphandle ngokupheleleyo kwindlela yehenjisi ngokwayo.
Ngenye imini (1 Feb 1976) uGeoff wathi gqi nomzobo wehenjisi ebukekayo engaqhelekanga neyintshayo.Ndamangaliswa!Andizange ndiyibone into ekude njengayo ngaphambili!
(Jonga umzobo ekhohlo).
Ndifunde ukuba le yindlela elungisiweyo ye-pantograph ebandakanya i-4-bar linkages.Asizange senze inguqulelo efanelekileyo yale hinge kodwa kwiinyanga ezimbalwa kamva uGeoff weza nenguqulelo ephuculweyo esiyenzileyo.
Inxalenye enqamlezayo yoguqulelo oluphuculweyo iboniswe ngezantsi:
'Iingalo' zale hinge zigcinwa zingqamene namalungu aphambili ajikelezayo ngamakrenki amancinci.Ezi zinokubonwa kwiifoto ezingezantsi.Iikranki kufuneka zithathe kuphela ipesenti encinci yomthwalo wehenjisi uwonke.
Ukulinganisa kwesi sixhobo kuboniswe kwividiyo engezantsi.(Enkosi kuDennis Aspo ngolu faniso).

Nangona lo matshini wehinge usebenze kakuhle, awuzange ufakwe kumatshini wokwenyani weMagnabend.Ukungaphumeleli kwayo yayikukuba ayizange ibonelele ngokujikeleza okupheleleyo kwe-180 yedigri yomqadi ogobayo kwaye kwakubonakala ngathi inamalungu amaninzi kuyo (nangona uninzi lwamalungu ayefana enye kwenye).
Esinye isizathu sokuba le hinge ingasetyenziswa kukuba uGeoff ke weza neyakhe:
I-Triaxial Hinge:
Ihinge ye-triaxial ibonelele ngokuzeleyo kwe-180 degrees yokujikeleza kwaye yayilula njengoko idinga iindawo ezimbalwa, nangona iindawo ngokwazo zazintsokothile.
Ihinge yetriaxial iqhubele phambili kwizigaba ezininzi ngaphambi kokufikelela kuyilo oluzinzile ngokufanelekileyo.Sibize iintlobo ezahlukeneyo zeHinge yeTrunnion, iHinge yaNgaphakathi eSpherical kunye neSpherical External Hinge.
Ihenjisi yangaphandle engqukuva yenziwe kule vidiyo ingezantsi (Enkosi kuJayson Wallis ngolu linganiso):

Zonke ezi ziyilo zichazwe kuxwebhu lweNgcaciso yePatent yase-US.(PDF).
Enye yeengxaki ezinkulu kwihinge yeMagnabend yayikukuba kwakungekho ndawo yokuyibeka!
Iziphelo zomatshini ziphumile kuba sifuna ukuba umatshini uvuleke, ngoko kufuneka uye kwenye indawo.Ngenene akukho ndawo phakathi kobuso bangaphakathi bomqadi ogobayo kunye nobuso bangaphandle bepali yangaphambili yemagnethi.
Ukwenza indawo sinokubonelela ngemilebe kumqadi ogobayo nakwipali engaphambili kodwa le milebe ibeka esichengeni ukomelela komqadi ogobayo kunye namandla okubamba umazibuthe.(Ungayibona le milebe kwiifoto zehenjisi ye-pantograph engentla).
Ngaloo ndlela i-hinge design ixinzelelwe phakathi kwesidingo sokuba ibe mncinci ukwenzela ukuba imilebe emincinci kuphela iya kufuneka kunye nesidingo sobunzima ukuze ibe namandla ngokwaneleyo.Kwaye nesidingo sokungabi naziko ukuze unikeze i-pivot ebonakalayo, ngokukhethekayo nje ngaphezulu komphezulu womsebenzi wemagnethi.
Ezi mfuno zafikelela kumyalelo omde kakhulu, kodwa uyilo oluyiqili lukaGeoff lwazisingatha kakuhle iimfuno, nangona umsebenzi omninzi wophuhliso (owandisiweyo ubuncinane iminyaka eli-10) wawufuneka ukuze kufunyanwe ezona zivumelwano zilungileyo.
Ukuba ndiceliwe ndingabhala inqaku elahlukileyo kwiihenjisi kunye nophuhliso lwabo kodwa okwangoku siza kubuyela kwimbali:
