Ngokukhula kwesidingo sayo yomibili imikhiqizo yekhwalithi ephezulu kanye nephephile, i-hemming sheet metal isiba umsebenzi ovame kakhulu emshinini wokunyathelisa.Futhi ngezisombululo eziningi ze-brake hemming emakethe, ukunquma ukuthi yisiphi isisombululo esilungele ukusebenza kwakho kungaba iphrojekthi ngokwayo.
Funda ngezansi ukuze ufunde kabanzi mayelana nezinhlobo ezahlukene zamathuluzi e-hemming, noma uhlole i-Hemming Series yethu futhi uthole izeluleko zochwepheshe ngethuluzi elingcono kakhulu le-hemming lezidingo zakho!
Hlola uchungechunge lwe-Hemming
Kuyini i-sheet metal hemming?
Njengasebhizinisini lezingubo kanye nokuthunga, i-hemming sheet sheet ihlanganisa ukugoqa ungqimba olulodwa lwento phezu kwesinye ukuze kwakheke umphetho othambile noma oyindilinga.Isetshenziswa ezimbonini eziningi ezihlanganisa iziqandisi, ukwenza ikhabethe, ukukhiqiza imishini yasehhovisi, okokusebenza kokucubungula ukudla, kanye nemishini yokubeka amashelufu neyokugcina ukubala nje okumbalwa.
Ngokomlando, i-hemming ibivame ukusetshenziswa ezintweni ezisukela ku-20 ga.ngo16 ga.insimbi emnene.Kodwa-ke, ngokuthuthukiswa kwakamuva kubuchwepheshe obutholakalayo be-hemming akuvamile ukubona i-hemming yenziwa ngo-12 - 14 ga., futhi ezimeni ezingavamile ngisho nokujiya njengo-8 ga.impahla.
Imikhiqizo yensimbi ye-Hemming sheet ingathuthukisa ubuhle, isuse ukuchayeka kwemiphetho ebukhali kanye nama-burrs ezindaweni lapho ingxenye ibingaba yingozi ukuyiphatha, futhi yengeze amandla engxenyeni eqediwe.Ukukhetha amathuluzi afanele wokusonta kuya ngokuthi uzobe ugoqa kaningi kangakanani nokuthi uhlela ukujiya yibuphi ubukhulu bezinto ezibonakalayo.
I-Hammer Toolshammer-ithuluzi-punch-and-die-hemming-process
Ubukhulu.ukujiya impahla: 14 gauge
Isicelo Esilungile: Kungcono kakhulu uma ukugoqa kwenziwa ngokungavamile futhi kunokuhluka okuncane kogqinsi lwempahla.
Ukugoba Okubanzi: Cha
Amathuluzi e-hammer ayindlela endala kakhulu yokubopha.Kule ndlela, umkhawulo wezinto ezibonakalayo ugotshwe ngesethi ye-acute angle tooling ku-engeli efakiwe engaba ngu-30 °.Ngesikhathi sokusebenza kwesibili, i-flange egobe ngaphambili iba isicaba ngaphansi kwesethi yamathuluzi okwenza isicaba, aqukethe i-punch futhi afe ngobuso obuyisicaba ukuze kwakheke umphetho.Ngenxa yokuthi inqubo idinga ukusethwa kwamathuluzi okubili, amathuluzi esando agcinwa kangcono njengenketho evumelana nebhajethi yemisebenzi ye-hemming engavamile.
Ubukhulu.ukujiya impahla: 16 gauge
Isicelo Esifanelekile: Kuhle kakhulu ekujikeni ngezikhathi ezithile kwezinto ezincane.Ilungele imiphetho “echotshoziwe”.
Ukugoba kwendawo yonke: Yebo, kodwa kunomkhawulo.
Inhlanganisela ye-punch and die (noma i-hemming emise okwe-U iyafa) isebenzisa isibhakela esinamandla esingu-30° esinomhlathi oyisicaba ngaphambili kanye nefa elimise okuka-U elinendawo ebanzi eyisicaba phezulu.Njengazo zonke izindlela zokusonta, ukugoba kokuqala kuhilela ukudala i-pre-gob engu-30ۡ°.Lokhu kufezwa yi-punch eshayela i-material ekuvulekeni okumise okuka-U kudayi.I-material ibe ibekwa phezu kwefashi bese i-pre-goba ibheke phezulu.I-punch iphinde ishayelwe phansi iye phansi endaweni evulekile emise okuka-U ku-dies ngenkathi umhlathi ophansi ku-punch uqhubeka ngesiteji sokucaba.
Ngenxa yokuthi i-hemming die ene-U-shaped hemming inodonga oluqinile lwensimbi ngaphansi kwendawo lapho ukusebenza okuphansi kwenzeka khona, umthamo omkhulu womthwalo ohlinzekwa yilo mklamo usebenza kahle kakhulu ekudaleni imiphetho "echotshoziwe".Ngenxa yokusetshenziswa kwe-punch ebukhali yokugoba kwangaphambili, ukufa kwe-hemming okumise okwe-U nakho kungasetshenziselwa izinhlelo zokusebenza zokugoba kwendawo yonke.
I-tradeoff yalo mklamo iwukuthi njengoba umhlathi oyisicaba utholakala ngaphambili kwesibhakela, kufanele ube nokujula kancane ukuze ugweme ukuphazamiseka kokubalulekile njengoba ujikela phezulu ukuze udale ukugoba kwangaphambili okungama-degree angu-30.Lokhu kujula okungajulile kwenza okubalulekile kuthambekele kakhulu ekuphumeni emhlathini oyisicaba ngesikhathi sesiteji sokucaba, okungadala umonakalo omkhulu eminwe yegeji yebhuleki yangemuva.Ngokuvamile, lokhu kufanele kube inkinga ngaphandle kwalapho okokusebenza kuyinsimbi, kunamafutha ngaphezulu, noma uma i-flange egobile ngaphambili igotshwe ibe yi-engeli efakiwe enkulu (evuleke kakhulu) kuno-30°.
I-hemming yezigaba ezimbili iyafa (i-spring-loaded)spring-loaded-hemming-process
Ubukhulu.ukujiya impahla: 14 gauge
Isicelo Esilungile: Okwezicelo ze-hemming ezingavamile ukuya kwezimaphakathi zobukhulu obuhlukahlukene bezinto.
Ukugoba Okubanzi: Yebo
Njengoba amabhuleki okucindezela kanye nesoftware kukhula amandla, ukufa kwesiteji okubili kwaduma kakhulu.Uma usebenzisa lezi zifa, ingxenye igotshwa nge-angle ebukhali engu-30° kanye ne-hemming die eno-30° acute angle V-opening.Izingxenye ezingaphezulu zalezi zifa zilayishwa entwasahlobo futhi ngesikhathi sokushibilika, into egobile ngaphambili ibekwa phakathi kwesethi yemihlathi eyisicaba ngaphambili kwefa bese umhlathi ongenhla ophansi ushayelwa phansi yi-punch ngesikhathi sokushaywa inqama.Njengoba lokhu kwenzeka, i-flange egobe ngaphambili ifinyezwa kuze kube yilapho unqenqema oluholayo luhlangana neshidi eliyisicaba.
Ngenkathi ishesha futhi ikhiqiza kakhulu, amafa e-hemming esiteji amabili anezinkinga zawo.Ngenxa yokuthi basebenzisa i-spring loaded top, kumele babe nengcindezi eyanele yasentwasahlobo ukuze babambe ishidi ngaphandle kokuwisa ngisho nokuncane kuze kuqale ukugoba kokuqala.Uma behluleka ukwenza kanjalo, impahla ingashibilika ngaphansi kwegeji yeminwe futhi ilimaze njengoba kwenziwa ukugoba kokuqala.Ngaphezu kwalokho, adinga ukuvulwa kwe-V okulingana nogqinsi oluphindwe kasithupha (okungukuthi, kumpahla enogqinsi luka-2mm, i-spring loaded hemming dies idinga ukuvulwa kwe-v okungu-12mm).
Amathebula okugoba amaDashi / amathebula ane-hemmingUmdwebo-we-Dutch-bending-table-hemming-process
Ubukhulu.ukujiya impahla: 12 gauge
Isicelo Esifanelekile: Ilungele ukusebenza kaningi kwe-hemming.
Ukugoba Okubanzi: Yebo.Inketho eguquguqukayo kakhulu yakho kokubili ukugoba nokugoba kwendawo yonke.
Ngokungangabazeki, inqubekelaphambili yesimanjemanje futhi ekhiqiza kakhulu yamathuluzi e-hemming “itafula lokugoba laseDashi,” elibuye libizwe ngokuthi “itafula lokugoba.”Njengokufa kwe-hemming elayishwe entwasahlobo, amatafula okugoba aseDutch afaka isethi yemihlathi eyisicaba ngaphambili.Kodwa-ke, ngokungafani ne-hemming elayishwe entwasahlobo iyafa, imihlathi ephansi etafuleni lokugoba lesiDashi ilawulwa ngamasilinda we-hydraulic.Amasilinda we-hydraulic enza kube nokwenzeka ukugoqa ugqinsi olubanzi lwempahla nezisindo ngoba udaba lokucindezela kwentwasahlobo luyaqedwa.
Ngokuphinda kabili njengesibambi sokufa, amatafula okugoba amaDashi abuye abonise amandla okushintshanisa amadigri angama-30, okubuye kube nomthelela ekhonweni lawo lokugoqa ugqinsi olubanzi lwempahla.Lokhu kuwenza abe nezinto ezihlukahlukene kakhulu futhi kuholela ekuncipheni okukhulu kwesikhathi sokusetha.Ukuba nekhono lokushintsha i-v-opening, kuhlangene nekhono lokusebenzisa amasilinda amanzi ukuvala imihlathi eyisicaba nakho kwenza kube nokwenzeka ukusebenzisa isistimu njengesibambi sokufa uma ingasetshenziswa ekusetshenzisweni kwe-hemming.
Izinto zokujiya ezijiyileUkuhambisa-ukucaba-phansi-ithuluzi-nama-roller
Uma ubheka ukujiya izinto eziwugqinsi kuno-12 ga., uzodinga ithuluzi eliphansi elithambile elinyakazayo.Ithuluzi eliphansi eliyisicaba elihambayo lingena esikhundleni sethuluzi eliyisicaba eliphansi elisetshenziswa ekusethweni kwethuluzi lesando ngodayi olunama-roller bearings, okuvumela ithuluzi ukuthi limunce umthwalo oseceleni odalwe ekusethweni kwethuluzi lesando.Ngokumunca umthwalo oseceleni ithuluzi elihambayo eliphansi eliphansi livumela izinto eziwugqinsi njengo-8 ga.ukuboshelwa ibhuleki lokucindezela.Uma ubheka ukujiya izinto eziwugqinsi kuno-12 ga., lena ukuphela kwendlela enconyiwe.
Ekugcineni, alikho ithuluzi le-hemming elifanele zonke izinhlelo zokusebenza ze-hemming.Ukukhetha ithuluzi elifanele lokucindezela i-brake hemming kuncike ekutheni yiziphi izinto zokwakha ohlela ukuzigoba nokuthi uzobe ugoqa kaningi kangakanani.Cabangela ububanzi begeji ohlela ukugoba, kanye nokuthi mangaki ukusetha okuzodingeka ukuze uqedele yonke imisebenzi edingekayo.Uma ungaqiniseki ukuthi yisiphi isisombululo se-hemming esilungele ukusebenza kwakho, xhumana nomthengisi wakho wamathuluzi noma i-WILA USA ukuze uthole ukubonisana kwamahhala.
