Namaze igihe nkora ku bibazo byinshi by’abasomyi – ndacyafite inkingi nke zo kwandika mbere yo kongera kubivuga. Niba wanyoherereje ikibazo ariko sinsubize, ndakwinginze tegereza, ikibazo cyawe gishobora kuba ari cyo gikurikiraho. Ubitekereje, reka dusubize ikibazo.
Q: Turimo kugerageza guhitamo igikoresho kizatanga santimetero 0.09. Najugunye ibice byinshi kugira ngo mbigerageze; intego yanjye ni ugukoresha kashe imwe ku bikoresho byacu byose. Ese wanyigisha uburyo nakoresha santimetero 0.09 kugira ngo nsobanure neza uburebure bw'umurambararo? uburebure bw'umurambararo?
A: Niba urimo gukora umwuka, ushobora kumenya igihe umurambararo w’umwuka ugonga ukubye inshuro imwe ukurikije ubwoko bw’ibikoresho. Buri bwoko bw’ibikoresho bufite ijanisha.
Kugira ngo ubone ijanisha ry'ibindi bikoresho, ushobora kugereranya imbaraga zabyo zo gukurura n'imbaraga zo gukurura za psi 60.000 z'ibikoresho byacu bya reference (icyuma gikonje gikonjesha cya karuboni nke). Urugero, niba ibikoresho byawe bishya bifite imbaraga zo gukurura za psi 120.000, ushobora kwemeza ko ijanisha rizaba inshuro ebyiri z'ibanze, cyangwa hafi 32%.
Reka dutangire n'ibikoresho byacu by'ingenzi, icyuma gikonjesha gikozwe mu buryo bwa karuboni nke gifite imbaraga zo gukurura za psi 60.000. Umwanya w'umwuka w'imbere w'iki gikoresho uri hagati ya 15% na 17% by'aho ufunguye, bityo akenshi dutangirana n'agaciro k'imikorere ka 16%. Uru rugero ruterwa n'itandukaniro ryabyo mu bikoresho, ubunini, ubukana, imbaraga zo gukurura, n'imbaraga zo gutanga umusaruro. Ibi bintu byose bifite ubushobozi bwo kwihanganira ibintu bitandukanye, bityo ntibishoboka kubona ijanisha nyaryo. Nta bice bibiri by'ibikoresho bimwe.
Ukurikije ibi byose, utangirana n'ikigereranyo cya 16% cyangwa 0.16 hanyuma ukagikuba n'ubugari bw'ibikoresho. Bityo rero, niba urimo gukora ibikoresho bya A36 birenga santimetero 0.551. Iyo icyuma gifunguye, umurambararo w'imbere wawe ugomba kuba hafi 0.088″ (0.551 × 0.16 = 0.088). Hanyuma uzakoresha 0.088 nk'agaciro k'umurambararo w'imbere ukoresha mu kubara uburyo bwo gukuba no gukuramo.
Niba uhora ubona ibikoresho bivuye ku mucuruzi umwe, uzashobora kubona ijanisha rishobora kukwegereza uburebure bw'imbere bw'umuraba urimo kubona. Niba ibikoresho byawe biturutse ku bacuruzi batandukanye, ni byiza gusiga agaciro k'impuzandengo kabazwe, kuko imiterere y'ibikoresho ishobora gutandukana cyane.
Niba ushaka kubona umwobo w'icyuma uzatanga umurambararo wihariye w'imbere, ushobora guhindura formula:
Uhereye aha ushobora guhitamo umwobo wa die uboneka hafi cyane. Menya ko ibi bifata ko radius y'imbere y'aho ushaka kugeraho ihuye n'ubugari bw'ibikoresho urimo gukora. Kugira ngo ubone umusaruro mwiza, gerageza guhitamo umwobo wa die ufite radius y'imbere y'aho ukorera hafi cyangwa ingana n'ubugari bw'ibikoresho.
Iyo uzirikanye ibi bintu byose, umwobo w'icyuma uhisemo uzaguha radius y'imbere. Nanone menya neza ko radius y'icyuma itarenga radius y'umwuka uri mu gikoresho.
Ibuka ko nta buryo butunganye bwo guhanura imirasire y'imbere bitewe n'ibintu byose bihinduka. Gukoresha ubu buryo bw'ubugari bwa chip ni itegeko rikwiye. Ariko, bishobora kuba ngombwa ko hatangwa ubutumwa bufite agaciro k'ijanisha.
Q: Vuba aha nakiriye ibibazo byinshi ku bijyanye n'uko igikoresho cyo gukurura gikoreshwa mu gukurura gikoreshwa mu gukurura. Nubwo tutarabibona ko ibi bibaho ku gikoresho cyacu, mfite amatsiko yo kumenya ingano y'ikibazo. Ndabona ko iyo igikoresho gifite amashanyarazi menshi, ahantu hadakoreshejwe amashanyarazi hashobora "gufata" igikoresho kandi ntigikore neza kuva ku gice kimwe ujya ku kindi. Uretse ibyo, hari ibindi bibazo?
Igisubizo: Udupfunyika cyangwa udupfunyika dushyigikira icyuma cyangwa dukorana n'ishingiro rya feri yo gukanda ntabwo dukunze gukoreshwa nk'ingufu. Ibi ntibivuze ko umusego w'umurimbo udashobora gukoreshwa nk'ingufu. Ibi birashoboka ko bitabaho.
Ariko, hari uduce duto tw'icyuma dubarirwa mu bihumbi dushobora guhinduka magnetique, byaba ari igice cy'igiti kiri mu gikorwa cyo gukata cyangwa radius gauge. Iki kibazo gikomeye gute? Ni iki gikomeye? Kuki? Iyo aka gace gato k'ibikoresho kadafashwe ku gihe, gashobora gucukura mu mwanya w'uburiri, bigatuma habaho ahantu hadakomeye. Iyo igice gifite magnetique gifite ubunini buhagije cyangwa bunini bihagije, gishobora gutuma ibikoresho byo mu buriri bizamuka ku nkengero z'aho binjirira, bigatuma igice cy'ibanze gihagarara neza cyangwa kingana, ibi bikaba byagira ingaruka ku bwiza bw'igice kirimo gukorwa.
Q: Mu nkuru yawe Uburyo Air Curves Ifata Ubukana, wavuze formula: Punch Tonnage = Agace k'inkweto x Ubunini bw'ibikoresho x 25 x Igipimo cy'ibikoresho. 25 ituruka he muri iki kigereranyo?
A: Iyi formula yakuwe muri Wilson Tool kandi ikoreshwa mu kubara toni zo gupfunyika kandi ntaho ihuriye no gushushanya; nayihinduye kugira ngo menye neza aho ipfundo rirushaho kuba rinini. Agaciro ka 25 muri formula yerekeza ku mbaraga z'umusaruro w'ibikoresho byakoreshejwe mu gukora formula. Byongeye kandi, iyi formula ntikikorwa, ahubwo iri hafi y'icyuma cya A36.
Birumvikana ko hakenewe byinshi kugira ngo hamenyekane neza aho icyuma gipfunyika n'umurongo wo gupfunyika. Uburebure bw'aho icyuma gipfunyika, agace gahuza izuru ry'icyuma n'ibikoresho, ndetse n'ubugari bw'icyuma bigira uruhare runini. Bitewe n'uko ibintu bimeze, icyuma kimwe cyo gupfunyika ku bikoresho bimwe gishobora gutanga ibyuma bipfunyika neza n'imirongo itunganye (ni ukuvuga ibyuma bifite uburebure bw'imbere bushobora kugaragara kandi nta migozi iri ku murongo wo gupfunyika). Uzasangamo igikoresho cyiza cyo gupfunyika ku rubuga rwanjye gisuzuma ibi bintu byose.
Ikibazo: Ese hari uburyo bwo gukuramo aho icyuma gikonjera inyuma y'icyuma? Hari igihe abatekinisiye bacu ba feri bakoresha utuyobo duto twa V tutavuze ku gishushanyo mbonera cy'ubutaka. Dukoresha uburyo busanzwe bwo gukata icyuma.
Igisubizo: yego na oya. Reka nsobanure. Niba ari ukugonda cyangwa gukanda hasi, niba ubugari bw'ibumba buhuye n'ubunini bw'ibikoresho byo gushushanya, umugozi ntugomba guhinduka cyane.
Niba uri gukora umwuka, uburebure bw'imbere bw'aho uhengamiye bugenwa n'umwobo w'aho uhengamiye hanyuma uhereye aho ufata uburebure bw'aho uhengamiye hanyuma ukabara ingano y'aho uhengamiye. Ushobora kubona inkuru nyinshi zanjye kuri iyi ngingo kuri TheFabricator.com; shakisha "Benson" urazibona.
Kugira ngo ikirere gikore neza, abakozi bawe b’abahanga bazakenera gushushanya icyuma gifata icyuma bakoresheje uburyo bwo gukuramo icyuma gishingiye ku gice cy’amazi cyakozwe n’icyuma gifata icyuma (nk’uko byasobanuwe muri "Bend Inside Radius Prediction" mu ntangiriro y’iyi nkuru). Niba umukoresha wawe akoresha icyuma kimwe n’igice cyagenewe gukora, igice cya nyuma kigomba kuba gifite agaciro k’amafaranga.
Dore ikintu kidakunze kugaragara cyane – inkuru y'ubumaji gato y'umusomyi ushishikajwe no gutanga igitekerezo ku nkuru nanditse muri Nzeri 2021 ivuga ngo “Ingamba zo Gufata Feri kuri Aluminium ya T6”.
Igisubizo cy'umusomyi: Mbere na mbere, wanditse inkuru nziza cyane ku bijyanye no gukora ibyuma. Ndagushimira ku bw'izo nkuru. Ku bijyanye no gufunga wavuze mu nkuru yawe yo muri Nzeri 2021, natekereje gusangira ibitekerezo bimwe na bimwe bivuye ku byo nanyuzemo.
Ubwo nabonaga bwa mbere uburyo bwo gukurura ibintu mu myaka myinshi ishize, bambwiye gukoresha itoroshi ya oxy-acetylene, gucana umwuka wa acetylene gusa, no gusiga irangi ku mirongo y'ibimera n'umukara ukomoka kuri umwuka wa acetylene wahiye. Icyo ukeneye ni umukara wijimye cyane cyangwa umurongo w'umukara gato.
Hanyuma shyira ogisijeni hanyuma ushyushye insinga uhereye ku rundi ruhande rw'igice kandi urebe kure ikwiye kugeza igihe insinga y'amabara wafashe itangiye gushonga hanyuma igashira burundu. Ubu bushyuhe busa n'aho ari bwo bukwiye bwo gufunga aluminiyumu bihagije kugira ngo itange ishusho ya dogere 90 nta kibazo cyo gucika. Ntabwo ukeneye gushushanya igice kikiri gishyushye. Ushobora kugireka kigakonja kandi kizakomeza gukonja. Ndibuka ko nabikoze ku rupapuro rwa 6061-T6 rufite ubugari bwa 1/8″.
Maze imyaka irenga 47 nkora cyane mu gukora ibyuma bikozwe neza kandi nahoraga mfite ubuhanga bwo kwihishahisha. Ariko nyuma y'imyaka myinshi, sinkibishyiramo. Ndabizi icyo nkora! Cyangwa wenda ndi umuhanga mu kwihishahisha. Uko byagenda kose, nashoboye kurangiza akazi mu buryo buhendutse bushoboka nta bikoresho byinshi byoroshye.
Hari ikintu kimwe cyangwa bibiri nzi ku bijyanye no gukora ibyuma, ariko ndemera ko ntari injiji na gato. Nishimiye gusangira namwe ubumenyi nakusanyije mu buzima bwanjye bwose.
