Ndanga ndichishanda ndichiongorora matambudziko akawanda evaverengi – ndichine mamwe makoramu ekunyora ndisati ndawana mhinduro zvakare. Kana makanditumira mubvunzo ndikasaupindura, ndapota mirirai, mubvunzo wenyu ungangove unotevera. Tichifunga izvozvo, ngatipindurei mubvunzo wacho.
Mubvunzo: Tiri kuedza kusarudza chishandiso chinopa 0.09 inches. Radius. Ndakarasa zvikamu zvakawanda kuti zviongororwe; chinangwa changu ndechekushandisa chidhindo chimwe chete pazvinhu zvedu zvese. Mungandidzidzisa here mashandisirwo e0.09″ kufanotaura dhayasi inokombama? Radius yekufamba?
A: Kana uri kugadzira mhepo, unogona kufanotaura kuti denderedzwa remhepo rinokombama sei nekuwedzera kuvhura kwedise nechikamu zvichienderana nerudzi rwechinhu chacho. Rudzi rwechinhu chimwe nechimwe chine chikamu charwo.
Kuti uwane huwandu hwezvimwe zvinhu, unogona kuenzanisa simba razvo rekudhonza nesimba rekudhonza re60,000 psi rezvinhu zvedu zvekutarisa (simbi yakaputirwa nekabhoni shoma). Semuenzaniso, kana zvinhu zvako zvitsva zvine simba rekudhonza re120,000 psi, unogona kufungidzira kuti huwandu hwacho huchava kaviri pane hwaro hwekutanga, kana kuti hunenge 32%.
Ngatitangei nezvinhu zvedu zvekutarisa, simbi yakaputirwa ine kabhoni shoma ine simba rekudhonza re60,000 psi. Huremu hwemukati hwechinhu ichi huri pakati pe15% ne17% yevhu rakavhurika, saka tinowanzo tanga nekushanda kwe16%. Rudzi urwu rwunokonzerwa nekusiyana kwarwo muzvinhu, ukobvu, kuomarara, simba rekudhonza, uye simba rekupa. Zvese izvi zvinhu zvine mhando dzakasiyana dzekutsungirira, saka hazvigoneke kuwana chikamu chaicho. Hapana zvidimbu zviviri zvezvinhu zvakafanana.
Uchifunga zvese izvi, unotanga nepakati pe16% kana 0.16 wobva wawedzera izvozvo neukobvu hwechinhu chacho. Saka, kana uri kugadzira chinhu cheA36 chakakura kupfuura 0.551 inches. Kana die yakavhurika, inside bend radius yako inofanira kunge iri 0.088″ (0.551 × 0.16 = 0.088). Uchashandisa 0.088 semutengo unotarisirwa weinside bend radius yaunoshandisa mukuverenga bend allowance uye bend subtraction.
Kana uchigara uchiwana zvinhu kubva kumutengesi mumwe chete, uchakwanisa kuwana chikamu chinogona kukuswededza pedyo ne inside bend radius yauri kuwana. Kana zvinhu zvako zvichibva kuvatengesi vakasiyana-siyana, zvakanaka kusiya chiyero chepakati chakaverengerwa, sezvo hunhu hwezvinhu hunogona kusiyana zvakanyanya.
Kana uchida kuwana gomba rinopa nzvimbo chaiyo yekukombama mukati, unogona kuchinja fomura iyi:
Kubva pano unogona kusarudza gomba rekufa riri pedyo. Cherechedza kuti izvi zvinofungidzira kuti dhayamita yemukati megomba raunoda kuwana inoenderana nehukobvu hwechinhu chauri kugadzira. Kuti uwane mhedzisiro yakanaka, edza kusarudza gomba rekufa rine dhayamita yemukati iri pedyo kana kuti yakaenzana nehukobvu hwechinhu chacho.
Kana ukafunga nezvezvinhu izvi zvese, gomba redhie raunosarudza richakupa radius yemukati. Ita shuwawo kuti punch radius haipfuure radius yekukombama kwemhepo iri muchinhu chacho.
Rangarira kuti hapana nzira yakakwana yekufanotaura kuti radii yemukati inokotama sei tichifunga nezvezvinhu zvose. Kushandisa aya maperesenti ehupamhi hwechip ndiwo mutemo wakarurama. Zvisinei, zvingangodiwa kuchinjana mameseji ane huwandu hweperesenti.
Mubvunzo: Munguva pfupi yapfuura ndakagamuchira mibvunzo yakati wandei nezve mukana wekushandisa magineti pakushandisa mudziyo wekukotamisa. Kunyange zvazvo tisina kuona izvi zvichiitika pamudziyo wedu, ndinoda kuziva kuti dambudziko racho rakakura sei. Ndinoona kuti kana mold yacho ine magineti akawanda, gomba rinogona "kunamatira" pamold uye harina kuumbwa nguva dzose kubva pane chimwe chinhu kuenda kune chimwe. Kunze kweizvozvo, pane zvimwe zvinonetsa here?
Mhinduro: Mabhureki kana mabhureki anotsigira die kana kuti anodyidzana ne press brake base haawanzo shandiswa magineti. Izvi hazvirevi kuti piro yekushongedza haigone kushandiswa magineti. Izvi hazvingaitiki.
Zvisinei, kune zviuru zvezvidimbu zvidiki zvesimbi zvinogona kuita magineti, kungave chidimbu chehuni chiri kudhindwa kana radius gauge. Dambudziko iri rakakura zvakadii? Zvakakomba. Sei? Kana chidimbu ichi chidiki chisina kubatwa nenguva, chinogona kunyura pamusoro pebasa remubhedha, zvichiita kuti pave nenzvimbo isina kusimba. Kana chikamu chine magineti chakakora zvakakwana kana kuti chakakura zvakakwana, chinogona kukonzera kuti mubhedha usimukire kumucheto kwechinhu chinoiswa, zvichiita kuti plate yepasi igare isina kuenzana kana kuti yakaenzana, izvo zvinozokanganisa kunaka kwechikamu chiri kugadzirwa.
Q: Muchinyorwa chako How Air Curves Get Sharp, wataura nezve formula: Punch Tonnage = Nzvimbo yeShangu x Ukobvu hwezvinhu x 25 x Material Factor. 25 inobva kupi mu equation iyi?
A: Fomura iyi yakatorwa kubva kuWilson Tool uye inoshandiswa kuverenga punch tonnage uye haina chekuita nekugadzira; ndakaigadzirisa kuti ndione kuti kona inokotama kupi. Kukosha kwe25 mufomura kunoreva simba rekugadzira rechinhu chinoshandiswa mukugadzira fomura. Nenzira, chinhu ichi hachichagadzirwi, asi chiri pedyo nesimbi yeA36.
Ehe, pane zvakawanda zvinodiwa kuti uverenge nemazvo nzvimbo yekukotama uye mutsetse wekukotama wetip yepunch. Kureba kwekukotama, nzvimbo yekubatanidza pakati pemhino yepunch nezvinhu, uye kunyange upamhi hwediyi zvinoita basa rakakosha. Zvichienderana nemamiriro ezvinhu, dhayamita imwechete yepunch yezvinhu zvakafanana inogona kugadzira makombama akapinza uye makombama akakwana (kureva, makombama ane radius yemukati inofungidzirwa uye isina makombama pamutsetse wefold). Uchawana karukureta yakanaka kwazvo yesharp bend pawebhusaiti yangu inofunga nezvezvinhu izvi zvese.
Mubvunzo: Pane nzira here yekubvisa kona yekukombama kubva pakaunda yekumashure? Dzimwe nguva mainjiniya edu ekudhinda mabhureki anoshandisa maburi madiki eV atisina kufunga nezvawo muhurongwa hwepasi. Tinoshandisa nzira dzakajairwa dzekukotama.
Mhinduro: hongu uye kwete. Regai nditsanangure. Kana iri kukotama kana kutsika pasi, kana hupamhi hwechiumbwa huchienderana nehukobvu hwechinhu chekuumba, buckle haifanirwe kuchinja zvakanyanya.
Kana uri kugadzira mhepo, radius yemukati memupendero inoonekwa neburi redhiyesi uye kubva ipapo unotora radius inowanikwa mudhiyesi woverenga deduction yekukombama. Unogona kuwana zvakawanda zvezvinyorwa zvangu nezvenyaya iyi paTheFabricator.com; tsvaga "Benson" uye uchazviwana.
Kuti kugadzira mhepo kushande, vashandi vako veinjiniya vachafanirwa kugadzira slab vachishandisa kupeta kwe bend zvichibva pa floating radius yakagadzirwa ne die (sezvakatsanangurwa mu "Bend Inside Radius Prediction" pakutanga kwechinyorwa chino). Kana mushandi wako achishandisa mold yakafanana nechikamu chaakagadzirirwa kuumba, chikamu chekupedzisira chinofanira kunge chakakosha mari yacho.
Heino chimwe chinhu chisingawanzoitika - mashiripiti emuworkshop kubva kumuverengi anofarira kutaura pamusoro pekoramu yandakanyora munaGunyana 2021 "Maitiro Ekubhureka eT6 Aluminum".
Mhinduro yemuverengi: Chekutanga, makanyora zvinyorwa zvakanaka kwazvo pamusoro pekushanda kwesimbi. Ndinokutendai nazvo. Nezve annealing yamakataura muchikamu chenyu chemunaGunyana 2021, ndafunga kugovera pfungwa dzangu kubva pane zvakaitika kwandiri.
Pandakatanga kuona nzira yekubatidza mvura makore mazhinji apfuura, ndakaudzwa kuti ndishandise tochi ye oxy-acetylene, ndibatidze gasi re acetylene chete, uye ndipende mitsetse yeforoma netsvina nhema inobva mugasi re acetylene rakatsva. Chaunongoda chete mutsetse webrown wakasviba kana kuti mutema zvishoma.
Wobva wabatidza okisijeni wodziisa waya kubva kune rimwe divi rechikamu uye kubva kure kusvika waya ine ruvara yawangobatanidza yatanga kupera simba yozonyangarika zvachose. Izvi zvinoita sekunge tembiricha yakakodzera yekubatidza aruminiyamu zvakakwana kuti ipe chimiro chemadhigirii makumi mapfumbamwe pasina matambudziko ekutsemuka. Haufanire kugadzira chikamu chichiri kupisa. Unogona kuchirega chichitonhora uye chicharamba chichibatidzwa. Ndinoyeuka ndichiita izvi papepa re6061-T6 rine gobvu re 1/8″.
Ndave ndichinyanya kushanda mukugadzira simbi dzakagadzirwa nemazvo kwemakore anopfuura 47 uye ndagara ndiine hunyanzvi hwekupfeka simbi dzakagadzirwa nemachira. Asi mushure memakore akawanda, handichazviisi. Ndinoziva zvandiri kuita! Kana kuti pamwe ndiri nani pakuzvigadzira nemachira. Chero zvazvingava, ndakakwanisa kuita basa iri nenzira isingadhuri zvakanyanya nekushandisa zvinhu zvishoma.
Ndinoziva chimwe chinhu kana zviviri nezvekugadzirwa kwesimbi, asi ndinobvuma kuti handisi munhu asingazivi. Ndine ropafadzo yekukuudzai ruzivo rwandakaunganidza muhupenyu hwangu.
