Izwi rekuti hemming rine mabviro aro mukugadzira machira uko mupendero wejira unopetwa pachezvawo wozosonwa kuvharwa.Musheet metal hemming zvinoreva kupeta simbi ichidzokera pairi.Kana uchishanda neBrake Press hems inogara ichigadzirwa mumatanho maviri maitiro:
Gadzira bend neAcute Angle Tooling musimbi, 30 ° inodiwa asi 45 ° inoshanda kune mamwe mamiriro.
Isa acute bend pasi pebhari rinoputika uye shandisa zvakakwana kumanikidza kuti upedze kuvhara bend.
Danho rekutanga rinoitwa zvakafanana nechero acute angle bend.Yechipiri nhanho yehemming process inoda imwe yekuwedzera kuziva kuti sei pane chikamu cheBrake Press opareta uye dhizaini dhizaini nekuti kona yesimbi simbi, bhara rinodzika rinoda kutsvedza pasi uye kure nesimbi.Mukuwedzera iyo chidimbu chebasa chinoda kutsvedza kubva pakati pemabhawa.Masimba maviri aya anozivikanwa se thrust forces.
Mufananidzo Wekusundidzira Masimba Kubva Hemming Sheet Metal
Izvi zvinoda kuti dhizaini rigadzirwe kuti rimirire simba rekurovera uye rirambe rakati sandara.Pamusoro pezvo zvinoda kuti mushandisi aise simba remberi kurwisa simbi simbi kudzivirira kuti isatsvedza kubva mufa.Aya masimba anonyanya kutaridzika pazvimedu zvakakora zvebasa zvine mapfupi flange.Tine zvinhu izvi mupfungwa ngationgororei matatu emhando dzakajairika dzehemming set ups uye midziyo iripo yekudhinda mabhureki.
Multi Tool Setup, Acute Tooling uye Flattening Die
Iyo yakapusa fomu yekumisikidza hemming kusanganisa maviri akasiyana setups.Yekutanga ndeye acute setup, uko iyo 30 ° bend inogadzirwa uchishandisa yakajairwa tooling.Kana iyo yekutanga bend yaitwa chikamu chinogona kuendeswa kune mumwe muchina, kana setup nyowani inoiswa mune yekutanga.Yechipiri setup iri nyore flattening bar.Iyo bend inoiswa pasi peiyo flattening bar uye yakavharwa.Kuseta uku hakudi chero yakakosha maturusi uye inogona kuve yakanakira kumhanya mapfupi, prototypes kana zvitoro zvebasa izvo zvinozoda kuumba hwakasiyana hurefu hwehem.Sezvimedu zvega zveBrake Press Tooling iyo acute tooling uye flattening bar inosiyana-siyana, uye wedzera kukosha kunze kwehemming.Iyo dhizaini kumashure kune ino sisitimu ndiyo iri pachena inodiwa yemaseti maviri akasarudzika, uyezve hapana trust control mukuita flattening.
Matanho maviri Hemming Punch uye Die Combination
Iyo nhanho mbiri hemming die inoshanda nekushandisa yakadzika yakatemerwa difa uye acute bakatwa punch.Kubhenda kwekutanga kunoshandisa chiteshi se av kuvhura kumhepo kuumba bend.Muchikamu chechipiri chibhakera chinotsvedza mugero sezvo punch yakavharwa uye mupendero wechibhakera unoshandiswa kudzikamisa simbi simbi.Kugadzika punch mukati meiyo chiteshi chefa kunodzosera simba rekupinza mufa, iro rinogona kuchengetedzwa zviri nyore kupfuura punch pachayo.Iyo drawback yerudzi urwu rwekufa ndeyekuti inoda kudzora kweCNC.Nekuda kwekusiyana kwehurefu pakati pekurova kwekutanga neyechipiri nhanho kugadzirisa nemaoko kwaizotora nguva yakawanda.Pamusoro pemhando iyi yekufa inogona kupatsanurwa zviri nyore kubva pamusoro pe tonnage, kusimbisa kudiwa kwekombuta inodzorwa kuchengetedza.
Nhanho nhatu Hemming Punch And Die
Imwe nzira yakajairika yekushandisa yakagadzirirwa chaizvo kugadzira hems nhanho nhatu, kana accordion mhando punch uye kufa.Iyo v yekuvhura inogara pamusoro pechitubu chakaremerwa padhi, inogara pamusoro pepasi pedhi.Muchikamu chekutanga iyo acute bend inogadzirwa mukuvhurika v mushure mekunge chitubu chatsikirirwa uye padhi yepamusoro yakagara padhi rezasi.Padanho rechipiri gondohwe repamusoro rinodzorwa uye zvitubu zviri pakati pebedhi repamusoro nerezasi rinoridzorera panzvimbo yaro.Iyo sheet simbi inozoiswa pakati pepamusoro nepasi pedhi uye punch yakavharwa pasi ichiendesa tonnage kuburikidza ne v kufa.Kusununguka kwakakosha kunopihwa kune v kufa kubvumidza chishandiso ichi pakubatana kwechishandiso.Nhungamiro pakati pepamusoro nepasi pedhi inodzivirira masimba ekusundidzira kubva pakukanganisa mamwe ese ekushandisa.Iyo yepasi inofa inopawo mushandisi chimwe chinhu chekusundidzira chidimbu chebasa kudzivirira kuti simbi rege kutsvedza kunze.Ichi chishandiso chinosarudzirwa mechanika, isiri CNC, mabhureki nekuti mutsauko mukureba wesitiroko idiki kwazvo, zvichiita kuti kugadzirisa kushoma nguva.Iyi kuseta zvakare inobvumidza iwe kushandisa yakajairwa acute punch.
Tonnage Inodiwa Pakuita Hemming
Iyo tonnage inodiwa pahemming ichaenderana nekusimba kwechinhu chako, ukobvu hwayo uye zvakanyanya kukosha kuti ndeupi rudzi rwehemu yaunoda kuumba.Madonhwe emisodzi nemahemu akavhurika haadi zvakawandisa sematani sezvinoita mupendero wakafuratira.Izvi zvinodaro nekuti iwe uri kungochinja iyo yemukati radius zvishoma, zvakanyanya iwe uri kungoenderera mberi bend yapfuura 30 °.Kana ukapfavisa simbi unenge uchigadzira mutserendende wobvisa mukati meradius.Iye zvino wave kugadzira simbi pane kungoipeta chete.Pazasi iwe unogona kuona hemming tonnage chati yesimbi inotonhora yakakungurutswa.
