Mubvunzo: Ndanga ndichinetseka kuti ndinzwisise kuti bend radius (sekutaura kwandakaita) mune zvakadhindwa ine chekuita nekusarudzwa kwematurusi.Semuyenzaniso, parizvino tiri kunetsa nezvimwe zvikamu zvakagadzirwa kubva ku0.5 ″ A36 simbi.Isu tinoshandisa 0.5 ″ dhayamita zvibhakera zvezvikamu izvi.radius uye 4 inches.kufa.Zvino kana ndikashandisa mutemo we20% uye ndikawanza ne4 inches.Pandinowedzera kufa kuvhura ne15% (yesimbi), ndinowana 0.6 inches.Asi mushandisi anoziva sei kushandisa 0.5 ″ radius punch kana kudhinda kuchida 0.6 ″ bend radius?
A: Wataura rimwe rematambudziko makuru akatarisana neindasitiri yesimbi.Iyi ipfungwa isiriyo iyo mainjiniya uye zvitoro zvekugadzira zvinofanirwa kurwisana nazvo.Kugadzirisa izvi, isu tinotanga nemudzi wechikonzero, nzira mbiri dzekugadzira, uye kusanzwisisa mutsauko uripo.
Kubva pakuuya kwemichina yekupeta muma1920s kusvika nhasi, vashandisi vakaumba zvikamu zvine mabhendi epasi kana zvikonzero.Kunyangwe kubhenda kwepasi kwabuda mufashoni mumakore makumi maviri kusvika makumi matatu apfuura, nzira dzekukotama dzichiri kupinda mukufunga kwedu patinobhenda simbi.
Maturusi ekukuya chaiwo akapinda mumusika mukupera kwema1970 uye akachinja paradigm.Saka ngatitarisei kuti maturusi echokwadi anosiyana sei kubva kune maturusi emupurani, kuti shanduko kune chaiyo maturusi yakachinja sei indasitiri, uye kuti zvese zvinoenderana sei nemubvunzo wako.
Mumakore ekuma1920, kuumbwa kwakachinja kubva ku disc brake creases kuenda kuV-shaped inofa ine mapiche anoenderana.A 90 degree punch ichashandiswa ne 90 degree die.Kuchinja kubva pakupetwa kuenda pakugadzira yaive nhanho huru yekuenda mberi kwesimbi yemarata.Inokurumidza, muchidimbu nekuti ichangobva kugadzirwa plate brake inobatidzwa nemagetsi - hapasisina kupeta nemaoko bend rega rega.Mukuwedzera, iyo bhureki yeplate inogona kukotama kubva pasi, iyo inovandudza kururama.Pamusoro pemageji ekumashure, iyo yakawedzera kurongeka inogona kuverengerwa kunyaya yekuti punch inotsikirira radius yayo mukati memukati mekukotama radius yechinhu.Izvi zvinowanikwa nekushandisa muromo wechishandiso kune ukobvu hwezvinhu zvishoma pane kukora kwezvinhu.Isu tese tinoziva kuti kana isu tichigona kuwana inogara inogara mukati bend radius, isu tinogona kuverenga iyo chaiyo kukosha kwekubvisa bend, bend allowance, kunze kuderedzwa uye K factor zvisinei kuti tiri kuita rudzii rwekubhenda.
Kazhinji zvikamu zvine zvakapinza mukati bend radii.Vagadziri, vagadziri uye mhizha vaiziva kuti chikamu chaizomira nekuti zvese zvaiita senge zvakavakwa patsva - uye zvamazvirokwazvo zvaive, zvichienzaniswa nanhasi.
Zvose zvakanaka kusvikira chimwe chinhu chiri nani chauya.Nhanho inotevera yekuenda mberi yakauya mukupera kwema1970 nekuunzwa kwematurusi epasi, macomputer manhamba controllers, uye advanced hydraulic controls.Iye zvino iwe une kutonga kwakazara pamusoro peiyo press brake uye masisitimu ayo.Asi iyo yekunongedza ndiyo chaiyo-yepasi chishandiso chinoshandura zvese.Mitemo yose yekugadzirwa kwezvikamu zvehutano yakashanduka.
Nhoroondo yekuumbwa izere nekusvetuka uye miganhu.Mukusvetuka kumwe chete, takabva pakusaenderana flex radii yemabhureki eplateti kuenda kune yunifomu flex radii yakagadzirwa kuburikidza nekutsika, priming uye embossing.(Cherechedza: Kushandura hakuna kufanana nekukanda; unogona kutsvaga mudura rezvinyorwa kuti uwane rumwe ruzivo. Zvisineyi, muchikamu chino ndinoshandisa "bend yepazasi" kureva nzira dzekupa nekukanda.)
Idzi nzira dzinoda matani akakosha kuti aumbe zvikamu.Ehe, munzira dzakawanda idzi inhau dzakaipa kune wepanhau brake, chishandiso kana chikamu.Nekudaro, ivo vakaramba vari iyo yakajairwa simbi yekupeta nzira kweanoda kusvika 60 makore kusvika iyo indasitiri yatora danho rinotevera rakananga kumhepo.
Saka, chii chinonzi kuumbwa kwemhepo (kana kukotama kwemhepo)?Inoshanda sei kana ichienzaniswa neyepasi flex?Kusvetuka uku zvakare kunoshandura nzira iyo radii inogadzirwa.Ikozvino, pachinzvimbo chekutsikirira mukati meradius yekubhenda, mhepo inoumba "inoyangarara" mukati meradius sechikamu chekuvhura kufa kana chinhambwe pakati pemaoko anofa (ona Mufananidzo 1).
Mufananidzo 1. Mukukotama kwemhepo, nharaunda yemukati yebhendi inotarirwa nehupamhi hwefa, kwete chidimbu chepunch.Iyo radius "inoyangarara" mukati mehupamhi hwefomu.Mukuwedzera, kudzika kwekupinda (uye kwete kufa kwekona) kunogadzirisa kona ye workpiece bend.
Yedu yereferensi zvinhu yakaderera alloy kabhoni simbi ine simba rekusimba re60,000 psi uye mhepo inogadzira radius inosvika gumi nematanhatu muzana yegomba rekufa.Iyo muzana inosiyana zvichienderana nerudzi rwezvinhu, fluidity, mamiriro uye humwe hunhu.Nekuda kwekusiyana kwesimbi simbi pachayo, iwo akafanotaurwa maperesenti haazombove akakwana.Zvisinei, vane chokwadi chaizvo.
Mhepo yakapfava yealuminium inoumba radius ye13% kusvika 15% yekuvhura kufa.Zvinhu zvinopisa zvakakanyiwa zvakabikwa uye zvine mafuta zvine mhepo yekugadzira radius ye14% kusvika 16% yekuvhura kufa.Cold yakakungurutswa simbi (yedu base tensile simba i60,000 psi) inoumbwa nemhepo mukati meradius ye15% kusvika 17% yekuvhura kufa.304 simbi isina Stainless airforming radius ndeye 20% kusvika 22% yefa gole.Zvekare, zvikamu izvi zvine huwandu hwehukoshi nekuda kwekusiyana kwezvinhu.Kuti uone huwandu hwechimwe chinhu, unogona kufananidza kusimba kwayo kune iyo 60 KSI tensile simba rezvinyorwa zvedu zvereferenzi.Semuenzaniso, kana zvinhu zvako zvine simba rekusimba re120-KSI, iyo percentage inofanira kuva pakati pe31% ne33%.
Ngatitii kabhoni simbi yedu ine simba rekusimba re60,000 psi, ukobvu hwe0.062 inches, uye inonzi mukati bend radius ye0.062 inches.Bendekedza pamusoro peV-gomba re 0.472 kufa uye fomura inoguma ichaita seizvi:
Saka yako yemukati bend radius ichave 0.075 ″ iyo iwe yaunogona kushandisa kuverenga mabhend allowances, K zvinhu, dhonza mukati uye bend kudonhedza nekurongeka, kureva kuti kana wako press brake opareta ari kushandisa maturusi akakodzera uye kugadzira zvikamu zvakatenderedza maturusi ari kushandiswa.
Mumuenzaniso, mushandisi anoshandisa 0.472 inches.Kuvhura chitambi.Mushandi akapinda muhofisi ndokuti, “Houston, tine dambudziko.Iri 0.075.Impact radius?Zvinoita sekuti tine dambudziko chairo;toenda kupi kuti tiwane imwe yacho?Iyo yepedyo yatinogona kuwana ndeye 0.078."kana kuti 0.062 inches.0.078 in. Iyo punch radius yakakurisa, 0.062 mukati. Iyo punch radius idiki kwazvo.
Asi iyi isarudzo isiriyo.Sei?Iyo punch radius haigadziri yemukati bend radius.Rangarira, isu hatisi kutaura nezve yepasi flex, hongu, muromo weanorova ndiyo yakasarudzwa.Tiri kutaura nezvekuumbwa kwemhepo.Upamhi hwematrix hunogadzira radius;chibhakera chinongova chinhu chinosundidzira.Ziva zvakare kuti iyo angle yekufa haikanganisi mukati meradius ye bend.Unogona kushandisa acute, V-shaped, kana chiteshi matrices;kana ese ari matatu aine hupamhi hwakafanana hwekufa, iwe unowana yakafanana mukati mebend radius.
Iyo punch radius inokanganisa mhedzisiro, asi haisi iyo inotaridza iyo bend radius.Ikozvino, kana iwe ukagadzira punch radius yakakura kupfuura iyo inoyangarara radius, chikamu chinotora pane yakakura radius.Izvi zvinoshandura bend allowance, contraction, K factor, uye bend deduction.Zvakanaka, haisiriyo sarudzo yakanaka, handizvo here?Iwe unonzwisisa - iyi haisi iyo yakanakisa sarudzo.
Ko kana tikashandisa 0.062 inches?gole radius?Kurova uku kunenge kwakanaka.Sei?Nekuti, zvirinani kana uchishandisa maturusi akagadzirwa, iri padyo sezvinobvira kune yakasikwa "inoyangarara" yemukati bend radius.Kushandiswa kweichi punch muchishandiso ichi kunofanirwa kupa kuchinjika uye kwakagadzikana kukotama.
Zvakanaka, iwe unofanirwa kusarudza punch radius inoswedera, asi isingapfuure, radius yechikamu chinoyangarara chimiro.Iyo idiki iyo punch radius inoenderana neyayangarara bend radius, iyo yakanyanya kusagadzikana uye inofanotaura kubhenda kuchave, kunyanya kana iwe ukapedzisira wabhenda zvakanyanya.Zvibhakera zvakatetepa zvakanyanya zvinopwanya zvinhu uye kugadzira mabhende akapinza asina kuenderana uye kudzokorora.
Vanhu vazhinji vanondibvunza kuti nei ukobvu hwezvinhu zvichingokosha pakusarudza gomba rekufa.Mazana anoshandiswa kufanotaura mhepo inoumba radius anofunga kuti mold iri kushandiswa ine mold kuvhura kwakakodzera kukora kwechinhu.Ndiko kuti, gomba rematrix harizove rakakura kana diki pane zvaidiwa.
Kunyangwe iwe uchigona kudzikisa kana kuwedzera saizi ye mold, iyo radii inowanzo kanganisa, ichichinja akawanda ekukotama basa kukosha.Iwe unogona zvakare kuona maitiro akafanana kana iwe ukashandisa isiriyo hit radius.Saka, poindi yakanaka yekutangira mutemo wechigunwe chekusarudza kuvhura kwefa kasere pane ukobvu hwezvinhu.
Pazvakanakisa, mainjiniya achauya kuchitoro votaura neanodhinda mabhureki.Ita shuwa kuti munhu wese anoziva mutsauko pakati pekuumba nzira.Tsvaga kuti ndedzipi nzira dzavanoshandisa uye zvinhu zvavanoshandisa.Tora runyoro rwese zvibhakera uye kufa zvavanazvo, wobva wagadzira chikamu chinoenderana neruzivo irworwo.Zvadaro, mune zvinyorwa, nyora pasi zvibhakera uye unofa zvakakosha pakugadziriswa kwechikamu.Ehe, iwe unogona kunge uine etenuate mamiriro kana iwe uchifanirwa kugadzirisa maturusi ako, asi izvi zvinofanirwa kunge zviri izvo kwete kwete mutemo.
Vashandisi, ndinoziva kuti mese munonyepedzera, ini pachangu ndaiva mumwe wavo!Asi aenda mazuva aungasarudza yako yaunofarira seti yezvishandiso.Nekudaro, kuudzwa kuti ndechipi chishandiso chekushandisa pakugadzira chikamu hazviratidzi hunyanzvi hwako.Chinongova chokwadi chehupenyu.Iye zvino takagadzirwa nemhepo yakatetepa uye hatichanyari.Mitemo yashanduka.
