Kana mabhureki anotsikisa mabhureki akapeta zviyo mu radius diki, kureva kuti mutsara wakapetwa wakafanana nehwezviyo, vanofanirwa kuziva nezvekutsemuka.Vadivelu Comedy Getty Images
Mubvunzo: Mune chimwe chezvinyorwa zvako zvakapfuura zvakanzi kuti makatsemuka anoumbwa "achitevera" nzira yefibers.Mashoko acho anogona kundivhiringa.Izvi zvinoreva here kuti mafiibhi acho ari perpendicular kana anoenderana nemutsetse wekupeta?
Ndiri kushanda pashinda iyi nokuti tiri kupeta 0.060 ″ gobvu 3003 H14 aruminiyamu (ona fig. 1) uye mugadziri wangu wemidziyo anoda kuti ndigadzire bend parallel kune zviyo nokuti zviri nyore kuti ashande nechishandiso ichi.Handina kufara nepfungwa iyi, asi ndinofunga ichashanda.Ziva zvakare kuti uku kubhenda kunozoitwa pamuchina wekurovera, kwete mabhureki ekudhinda, asi ndiri kufunga kuti mamwe emitemo yekugadzira simbi inoshanda.Chero humwe hutungamiri pamusoro penyaya iyi hunogona kufarirwa zvikuru.
Mhinduro: Ndisati ndanyura mumusoro wenyaya, ndinoda kutaura nezve matauriro ako nezve verbosity.Kuvhiringidzika mukutaura nderimwe rematambudziko makuru akatarisana neindasitiri yedu.Chirevo ichi ndechechokwadi ungave uri mukirasi kana kukurukura nezvechirongwa chiri kubasa.
Mamwe mazwi ekutengeserana anochinjika.Kink yemunhu muganho haigone kuve yemumwe munhu k-factor, uye k-factor haisi yekubvisa kink - kunyangwe chitoro chandakaenda nacho.Nekuti aya mazwi ane chirevo chaicho uye mashandisirwo, kuashandisa zvisizvo kunogona kuomesa pfungwa uye kuita kuti zviome kugadzira zvikamu zvemhando yepamusoro.Kushandisa zvisizvo kwemazwi kunowanzonetsa kugadzirisa, uye munhu wese achapa mhinduro imwechete kumubvunzo wekuti sei vachishandisa izwi nenzira yavanoita: nekuti ndiwo madzidzire andakaita.
Kuti uchengetedze munhu wese ari papeji imwe chete uye kushandisa mazwi nenzira kwayo, ini ndinokurudzira kutumira iri nyore laminated wall chart kana handout ine tsanangudzo dzose dzakakodzera.Hezvino zvimwe zvinhu zvaunogona kugonesa:
Aya angori mashoma etsanangudzo dzakakodzera, kune akawanda akawanda.Zvisinei, kana munhu wose awana mutauro zvakanaka - zvakanaka, unouwana.
Iye zvino dzokera kune musoro uri kukurukurwa: hukama hwekutungamira kwefibers kune mitsetse yebhendi.Muchinyorwa chakapfuura, ndakashandisa "grained bend" apo mutsara wakapeta wakanga wakaenzana nekutungamira kwemafiber, sezvinoratidzwa mumufananidzo 1. "Side" kana "lateral" mapepa ndeye apo mutsara wekupeta uri perpendicular kune kutungamira kwe iyo fiber, iyo inoita kuti peta rive rakasimba uye risinganyanyi kutsemuka (ona Mufananidzo 2).
Kubhenda kwakatarisana nemafiibhi kunopa kubhenda kusina simba kupfuura mutsetse unomonereka unofamba uchipikisana neshinda kana kuti kuyambuka shinda.Pamusoro pazvo, radius yekunze yekubhenda inonyanya kuputika kana yakakotama ichienderana nekutungamira kwefibers.Iyo diki yemukati radius paunenge uchikotama uchienderana nekutungamira kwefibers, iyo yakakura mukana wekuputika uye kusimba kwekutsemuka kuchave.Kushandisa bend radii yakakura kunogona kubatsira kudzivirira matambudziko aya.
Zvinotora simba rakawanda kupeta chidimbu chechinhu kana mutsara wapetwa uchiyambuka magadzirirwo, asi kubhenda kwakafanana kuburikidza nekugadzirwa kunochengetedza diki mukati mebend radius.Pamusoro pezvo, kudzika kwekupinda kunogona kushanduka panguva yekukotama zvichienderana nekumisikidzwa kwezviyo newaya yekupeta.
Hazvisi zvese zvinhu zvine gwara rezviyo.Mhangura haina tsanga;mune inopisa yakakungurutswa yakanyungudutswa uye yakaoirwa simbi (HRP&O) tsanga dziripo, nepo munyoro inotonhora yakakungurutswa tsanga dzesimbi dzinogona kududzirwa.Mune simbi dzisina tsvina, zvakaoma uye dzimwe nguva hazvibviri kuona zviyo uye maitiro avo.Zvishandiso zvine mutsara wezviyo zvinokanganisa makona ekubhenda zvinonzi anisotropic.Zvishandiso zvisina iyi pfuma zvinoonekwa isotropic.
Mufananidzo 1. Mabhende ezviyo (kureva kuti mutsara wekupeta unofambirana negwara rezviyo) anowanzo putika.
Imwe yedzakanakisa nzira dzekudzikisa kutsemuka ndeyekuchengeta iyo yemukati bend radius iri padyo nehupamhi hwezvinhu sezvinobvira, kunyangwe iyo yemukati bend radius kune yenyama ukobvu reshiyo iri padyo kune imwe kune imwe sezvinobvira.Diki radii inodhonza zvinhu zvakasimba mubend, izvo zvinosundira zviyo zvakasiyana, zvichiita sezvimedu.Iwe hauzowanzoona mitswe mumabhendi ane radii yakakura kupfuura ukobvu hwezvinhu.Dzimwe nguva zviyo zvinogona kutyorwa nekuda kwekunyanya kutambanudza kana kurebesa kweradius yekunze.Sezvo mutemo, izvi zvinoshanda kune zvishoma ductile kana yakakwirira-kupisa zvinhu, zvakadai T-6 aluminium.Zvisinei, mitswe yakadaro haiwanzoitiki.
Kana iwe uchifanira kukotama nezviyo uye kutsemuka kuchiri dambudziko, unogona kushandisa zvinhu zviri annealed state wobva wazvipisa kana zvichidikanwa.Semuenzaniso, unogona kugadzira aluminium yakapfava uye wobva waomesa kune T-6 hasha.
Chimbofungawo rudzi rwekubhenda kwauri kuita.Offset mabhendi ane hunyengeri kutanga nekuti chishandiso chinodzora pakati flange.Kuganhurirwa uku kunoguma nekuwedzera kwekubhenda kumwe kunhu, kunyanya kune maviri ekunze flanges.Kuchinja uku mukurebesa kunoita kuti vasatarisike muhukuru.Izvi zvinogadzirisa zvinoshandawo zvakanyanya nediki bend radii, iyo inogona kuwedzera matambudziko ekutsemuka.
Kana iwe waizogadzira chikamu ichi pamushini wekugadzira roll, ingangoita pasi kunze (nekuti maitiro ekugadzira pachawo haana kukodzera kuumbwa kwemhepo), saka haungakwanise kushandisa nzira dzekugadzira mhepo kuderedza kutsemuka.Nekudaro, kuwedzera diki diki yeangular clearance kune inofa seti kuchabatsira kuchengetedza curved flanges kufanana.Zvichienderana nerudzi rwezvinhu uye kuwanda kweiyo elasticity inowanikwa mune ino chinyorwa, imwe kana maviri madhigirii anokwana.Iyo imwe-kune-imwe reshiyo pakati pezvinhu ukobvu uye mukati bend radius inobatsira kuchengetedza maflange akaenzana.
Saizi yezviyo inokanganisawo zvakanyanya simba regoho.Zvishandiso zvine tsanga dzakatsetseka hazvinyanyi kupatsanura uye kutsemuka uye zvine simba regoho repamusoro, zvichipa chikonzero chakanaka chekutenga zvinhu zvemhando yepamusoro kunyangwe zvichidhura.Nekudaro, mari yekuwedzera yezvinhu inogadziriswa zviri nyore nekuderedzwa marara uye kuchengetedza kwevashandi nekuda kwemhando dzemhando.
Miganhu yezviyo inoitawo basa rekuparadzanisa uye kuputika zviyo nekuvhiringidza kufamba kwezvinonzi dislocation.Iyo diki saizi yezviyo, yakakura iyo yakazara nzvimbo ye.muganhu, zvakanyanya kuoneka kukanganisa uye zvakanyanya kugadzikana uye nguva dzose simba regoho.
Kuti uwane rumwe ruzivo nezvenyaya iyi, unogona kutarisa makoramu angu apfuura, anosanganisira "Material Grain Size Matters muSheet Metal Bending", "Maitiro Anoita Simbi Yezviyo Kushanda Kushanda" uye "Material Grain size pane Inobhenda Die" .mu thefabricator.com search bar.
Kutsika kwakasiyana chaizvo nekugadzira mabhureki ekudhinda, asi kune zvakawanda zvakafanana, kusanganisira kupatsanurwa kwezviyo uye kuputika kunze kwekubhenda.Kakawanda tinoshaya zvokuita kunze kwokuteerera zviyo, asi pane zvinhu zvakawanda zvatinogona kuita kuti tideredze migumisiro inokuvadza yokuteerera zviyo.
Mufananidzo 2. Bend pamwe chete nefibers (kureva, kana kutungamira kwefibers perpendicular to bend) inopa bend yakasimba uye isinganyanyi kuputika.
FABRICATOR ndiyo inotungamira muNorth America kugadzira simbi uye kugadzira magazini.Magazini inoburitsa nhau, zvinyorwa zvehunyanzvi uye nyaya dzebudiriro dzinogonesa vanogadzira kuita basa ravo nemazvo.FABRICATOR anga ari muindasitiri kubva 1970.
Yakazara yedhijitari yekuwana kuThe Tube & Pipe Journal yave kuwanikwa, ichipa nyore kuwana kune yakakosha indasitiri zviwanikwa.
Nakidzwa nekuwana kwakazara kwedhijitari kuSTAMPING Journal, iyo simbi inotsikisa musika magazini ine yazvino kufambira mberi kwetekinoroji, maitiro epamusoro uye nhau dzeindasitiri.
Kuwana kuzere kuThe Fabricator en Español digital edition yave kuwanikwa, ichipa nyore kuwana kune yakakosha indasitiri zviwanikwa.
Adam Hickey weHickey Metal Fabrication anojoinha podcast kuti ataure nezve kufamba-famba uye kushandura kugadzirwa kwemarudzi mazhinji…
