Ndanga ndichishanda kuburikidza nekuseri kwenyaya dzevaverengi - ndichine makoramu mashoma ekunyora ndisati ndabata zvakare.Kana wakanditumira mubvunzo ndikasaupindura, chimbomira, mubvunzo wako unogona kutevera.Tichifunga izvozvo, ngatipindure mubvunzo.
Q: Tiri kuedza kusarudza chishandiso chinopa 0.09 inches.radius.Ndakakandira kunze boka rezvikamu zvekuedzwa;chinangwa changu ndechekushandisa chitambi chimwe chete pazvinhu zvedu zvese.Unogona kundidzidzisa kushandisa 0.09 ″ kufanotaura bend radius?travel radius?
A: Kana iwe uri kugadzira mhepo, unogona kufanotaura bend radius nekuwanza kuvhurwa kwefa nechikamu zvichienderana nerudzi rwezvinhu.Mhando yega yega yezvinhu ine chikamu chezana.
Kuti uwane mapeji ezvimwe zvinhu, unogona kuenzanisa simba ravo rekusimba ne60,000 psi tensile simba rereferensi yedu (yakaderera kabhoni inotonhora yakakungurutswa simbi).Semuenzaniso, kana zvinhu zvako zvitsva zvine simba rekusimba re120,000 psi, unogona kufungidzira kuti chikamu chichapeta kaviri pane yekutanga, kana 32%.
Ngatitangei neyedu yereferensi zvinhu, yakaderera kabhoni inotonhora yakakungurutswa simbi ine tensile simba re60,000 psi.Iyo yemukati magadzirirwo emhepo radius yechinhu ichi iri pakati pe15% ne17% yekuvhura kwekufa, saka isu tinowanzo tanga nemutengo wekushanda we16%.Rudzi urwu rwunokonzerwa nekusiyana kwavo kwemukati mune zvinhu, ukobvu, kuoma, kusimba kwesimba, uye goho simba.Zvese zvezvinhu izvi zvinhu zvine huwandu hwekushivirira, saka hazvigoneke kuwana chaiyo muzana.Hapana zvidimbu zviviri zvezvinhu zvakafanana.
Uine zvese izvi mupfungwa, unotanga nepakati pe16% kana 0.16 uye wowedzera iyo neukobvu hwezvinhu.Naizvozvo, kana iwe uri kugadzira A36 zvinhu zvakakura kupfuura 0.551 inches.Nekufa kwakavhurika, yako yemukati bend radius inofanirwa kunge iri 0.088 ″ (0.551 × 0.16 = 0.088).Iwe unozoshandisa 0.088 seyaitarisirwa kukosha kwemukati bend radius yaunoshandisa mubend allowance uye bend kubvisa macalculation.
Kana iwe uchigara uchiwana zvinhu kubva kumutengesi mumwe chete, iwe unozokwanisa kuwana chikamu chinogona kukuswededza pedyo nemukati bend radius yauri kuwana.Kana zvinhu zvako zvichibva kune vakati wandei vakasiyana vatengesi, zviri nani kusiya yakaverengerwa kukosha kwepakati, sezvo zvinhu zvenyama zvinogona kusiyana zvakanyanya.
Kana iwe uchida kutsvaga gomba rinofa iro rinopa chaiyo mukati bend radius, unogona kushandura fomula:
Kubva pano iwe unogona kusarudza iyo yepedyo inowanikwa die gole.Ziva kuti izvi zvinofungidzira kuti iyo yemukati radius yekubhenda iwe yaunoda kuwana inofanana nekukora kwezvinhu zvauri kuita nemhepo.Kuti uwane mibairo yakanaka, edza kusarudza kuvhura kwekufa kune mukati bend radius iri padyo kana kuenzana neukobvu hwezvinhu.
Paunotora zvese izvi zvinhu mukufunga, gomba rekufa raunosarudza rinokupa iyo yemukati radius.Zvakare ita shuwa kuti punch radius haipfuure kubhenda radius yemhepo mune izvo zvinhu.
Ramba uchifunga kuti hapana nzira yakakwana yekufanotaura yemukati bend radii yakapihwa ese zvinhu zvinosiyana.Kushandisa aya chip wide percentage ndiwo mutemo wakanyatsojeka wegunwe.Nekudaro, zvingave zvakafanira kuchinjana mameseji nehuwandu hwehuwandu.
Mubvunzo: Nguva pfupi yadarika ndakatambira kubvunza kwakati wandei nezve mukana wekuita magineti chishandiso chekupeta.Kunyange tisina kuona izvi zvichiitika nechokushandisa chedu, ndiri kuda kuziva nezve kukura kwedambudziko.Ndinoona kuti kana mold yakanyatso magnetized, iyo isina chinhu inogona "kunamatira" kune mold uye kwete kuumba nguva dzose kubva pane chimwe chikamu kuenda kune chinotevera.Kunze kwaizvozvo, pane kumwe kunetseka here?
Mhinduro: Mabhureki kana mabhureki anotsigira kufa kana kudyidzana neiyo press brake base haawanzo magnetized.Izvi hazvirevi kuti piro yekushongedza haigoni kuve nemagnetized.Izvi hazvigoni kuitika.
Nekudaro, kune zviuru zvezvimedu zvidiki zvesimbi zvinogona kuita magineti, ingave chidimbu chehuni mukutsikisa kana kuti radius gauge.Dambudziko iri rakakura sei?zvakakomba.Sei?Kana ichi chiduku chiduku chechinhu chisina kubatwa munguva, chinogona kuchera mukati mebasa remubhedha, zvichiita nzvimbo isina simba.Kana iyo magineti chikamu chakakora kana kuti chakakura zvakakwana, chinogona kuita kuti zvinhu zvemubhedha zvisimuke zvakatenderedza mipendero yekuisa, zvichiwedzera kukonzera kuti base plate igare zvisina kuenzana kana zvakaenzana, izvo zvinozokanganisa kunaka kwechikamu chiri kugadzirwa.
Mubvunzo: Muchinyorwa chako Maitiro eMhepo Anopinza Akapinza, wakataura nezve formula: Punch Tonnage = Gasket Area x Material Thickness x 25 x Material Factor.Ko 25 inobva kupi mukuenzanisa uku?
A: Iyi fomula inotorwa kubva kuWilson Tool uye inoshandiswa kuverenga punch tonnage uye haina chekuita nekuumbwa;Ndakaigadzirisa kuti ione kuti iko kubhenda kunokwira kupi.Kukosha kwemakumi maviri neshanu mufomura inoreva simba regoho rechinhu chinoshandiswa mukugadzira fomula.Nenzira, chinhu ichi hachina kugadzirwa, asi chiri pedyo neA36 simbi.
Ehe, zvimwe zvakawanda zvinodikanwa kuti uverenge chaizvo nzvimbo yekukotama uye mutsara wekupeta wepanch tip.Kureba kwebhendi, nzvimbo yekubatanidza pakati pemhino yepunch uye zvinhu, uye kunyange hupamhi hwefa inoita basa rinokosha.Zvichienderana nemamiriro ezvinhu, iyo imwechete punch radius yechinhu chimwe chete inogona kuburitsa mabhende akapinza uye mabhendeti akakwana (kureva kubhenda neine fungidziro yemukati radius uye pasina creases pamutsetse wekupetwa).Iwe uchawana yakanakisa yakapinza bend Calculator pawebhusaiti yangu iyo inotora ese akasiyana aya muaccount.
Mubvunzo: Pane nzira yekubvisa iyo bend kubva pakaunda kumashure?Dzimwe nguva nyanzvi dzedu dzekutsikisa mabhureki dzinoshandisa maV-maburi madiki atisina kuzvidavirira muurongwa hwepasi.Isu tinoshandisa yakajairwa bending deductions.
Mhinduro: hongu uye kwete.Rega nditsanangure.Kana ichikotama kana kutsika pasi, kana hupamhi hwemuumbi hunoenderana nehupamhi hwezvinhu zvekuumba, buckle haifaniri kuchinja zvakanyanya.
Kana iwe uri kuumba mhepo, iyo yemukati radius yekubhenda inotarirwa negomba rekufa uye kubva ipapo iwe unotora radius inowanikwa mufa uye kuverenga iyo bend deduction.Unogona kuwana zvakawanda zvezvinyorwa zvangu panyaya iyi paTheFabricator.com;tsvaga "Benson" uye iwe uchavawana.
Kuti airforming ishande, vashandi vako veinjiniya vanozoda kugadzira slab vachishandisa bend kubvisa zvichienderana neradius inoyangarara yakagadzirwa nefa (sezvinotsanangurwa mu "Bend Inside Radius Prediction" kwekutanga kwechinyorwa chino).Kana mushandisi wako ari kushandisa mold yakafanana nechikamu chayakagadzirirwa kuumba, chikamu chekupedzisira chinofanira kunge chakakosha mari.
Hechino chimwe chinhu chisingawanikwe - kadiki mashiripiti emusangano kubva kumuverengi anofarira kutaura pane koramu yandakanyora munaGunyana 2021 "Braking Strategies yeT6 Aluminium".
Mhinduro yevaverengi: Chekutanga pane zvese, wakanyora zvinyorwa zvakanaka pane pepa resimbi rinoshanda.Ndinokutendai nokuda kwavo.Nezve kuwedzererwa kwawakatsanangura muchikamu chako chaGunyana 2021, ndafunga kuti ndichagovera dzimwe pfungwa kubva pane zvakaitika kwandiri.
Pandakatanga kuona huchenjeri hwekunyudza makore mazhinji apfuura, ndakanzi ndishandise tochi yeoxy-acetylene, kubatidza gasi reacetylene chete, uye kupenda mitsetse yeforoma nesoot nhema kubva mugasi rakapiswa reacetylene.Chaunongoda mutsara wakasviba wakanyanya kana mutema zvishoma.
Wobva wabatidza okisijeni wopisa waya kubva kune rumwe rutivi rwechikamu uye kubva kure kure kusvika waya yeruvara yauchangobva kubatanidza yatanga kupera uye yobva yanyangarika zvachose.Iyi inoita kunge tembiricha chaiyo yekubatisa aruminiyamu inokwana kupa chimiro che90 degree pasina nyaya dzekutsemuka.Haufanire kuumba chikamu chichiri kupisa.Unogona kuita kuti itonhore pasi uye icharamba ichivharwa.Ndinorangarira ndichiita izvi pa1/8 ″ gobvu 6061-T6 pepa.
Ndanga ndakabatikana zvakadzama mukugadzira simbi yemapepa kweanopfuura makore makumi mana nemanomwe uye ndagara ndiine hunyanzvi hwekufukidzira.Asi mushure memakore akawanda kudaro, handichaiisa zvakare.Ndinoziva zvandiri kuita!Or maybe I'm just better at disguise.Chero zvazvingava, ndakakwanisa kuita kuti basa riitwe nenzira ine mari yakawanda sezvinobvira nemafiritsi mashoma.
Ndinoziva chinhu kana zviviri nezvekugadzirwa kwesimbi, asi ndinoreurura kuti handisi kusaziva.Rukudzo rukuru kwandiri kugoverana nemi ruzivo rwandakaunganidza pamusoro pehupenyu hwangu.
