Paunenge uchigadzira mukufa kunofambira mberi, isina mubati kumanikidzwa, mamiriro ekumanikidza, uye zvigadzirwa zvese zvinokanganisa kugona kuwana zvinowirirana zvakatambanudzwa pasina kuunyana.
Mubvunzo: Tiri kutora makapu kubva mugiredhi 304 simbi isina tsvina.Pakutanga kumira kwekufa kwedu kunofambira mberi, tinokwevera kune inenge 0.75 masendimita yakadzika.Pandinotarisa hupamhi hweflange perimeter yechinhu chisina chinhu, mutsauko kubva kune rumwe rutivi kusvika kune rumwe rutivi unogona kuva wakakwirira se 0.003 inches.Kurova kwese kwakasiyana uye hakuoneki mune imwe nzvimbo yekugadzira yave yakataurirwa chinhu chakafanana, ini ndanga ndaudzwa chinhu chakafanana. Kumucheto kwekona yekoiri huru. Tingawana sei kapu yakaumbwa inoramba yakaumbwa isina kuunyana?
A: Ndinoona mubvunzo wako unomutsa mibvunzo miviri: yekutanga, shanduko yaunowana mukuita lottery, uye chechipiri, iyo mbishi zvinhu uye mataurirwo azvo.
Mubvunzo wekutanga une chekuita nekukanganisa kwekugadzira maturusi, saka ngationgororei izvo zvakakosha.Kukwinya kusingadzoreki uye kuchinja kwemashure ukobvu hwekapu kunoratidza kusakwana kwekushandisa pachiteshi chako chinofambira mberi chekudhirowa.Pasina kuona dhizaini yako yekudhirowa, ndingatofanirwa kufunga kuti yako yekudhirowa punch uye kufa radii uye mikaha yadzo inosangana neyakagadzika magadzirirwo paramita.
Mukudhirowa kwakadzika, iyo isina chinhu inobatwa pakati peiyo dhizaini yekufa uye isina chinhu inobata, nepo iyo yekudhirowa punch inokwevera zvinhu mudhirowa kufa, ichiikwevera ichitenderedza radius yekudhirowa kuti iite goko.Pane kukakavara kwakawanda pakati pekufa nemubati asina chinhu.Mukati mekuita uku, zvinhu zvinodzvanywa nechemberi, ndicho chikonzero chekukwinya uye kurebesa kweradial elongation yechinhu chisina kuvharwa, kana kuyerera kweiyo kuyerera kunenge kwanyanya kuyerera kwechinhu chisina chinhu. pasi pekudhonza kwekutambanudza punch.Kana yakanyanya kuderera, wrinkling ichaitika.
Pane muganhu pakati peshell diameter uye dhayamita isina chinhu isingagoni kudarika kuti ibudirire kudhirowa kushanda.Muganhu uyu unosiyana nepercent elongation yezvinhu.Mutemo mukuru ndewe 55% kusvika 60% yekutanga kudhirowa uye 20% kune imwe neimwe inotevera kudhirowa. zvinodiwa, asi zvakaoma kuwedzera mushure mekunge dhizaini yapera).
Iyo isina chinhu inobata pressure p ndeye 2.5 N/mm2 yesimbi, 2.0 kusvika 2.4 N/mm2 yemhangura alloys uye 1.2 kusvika 1.5 N/mm2 yealuminium alloys.
Kusiyana kwehupamhi hweflange kunoratidzawo kuti dhizaini yako yekugadzira haina kusimba zvakakwana.Bhutsu dzako dzekuumbwa dzinofanira kunge dzakakora zvakakwana kuti dzimire kudhonza pasina buckling.Rutsigiro pasi peshangu inofa inofanira kunge iri simbi yakasimba, uye pini yedhiraivha inofanira kunge yakakura zvakakwana kudzivirira chero kufamba kweparutivi kwepamusoro uye pasi kufa panguva yekutambanudza.
Tarisawo nhau dzako.Kana madhiri enhau akasakara uye asina kusimba, hazvina basa kuti chishandiso chako chakasimba - hausi kubudirira.Ona siraidhi yekutsikirira kuti uone kuti kureba kwemuchina wekudhinda ndeyechokwadi uye mativi mana. Ona kuti mafuta ako ekudhirowa akanyatsopepetwa uye akachengetedzwa, uye kuti vhoriyamu yekushandisa uye nzvimbo yemuromo zvakagadziriswa.Kunyatsoongorora, nyatso ongorora uye nyatso ongorora uye nyatso tarisa kumusoro. kubhadhara zvakanyanya kudhirowa radii; geometry yavo uye kupera kwepamusoro kunofanirwa kuve kwakakwana.
Zvakare, nepo vatengi vachiwanzoona 304L uye standard 304 seinochinjika, iyo 304L ndiyo iri nani sarudzo yekudhirowa.L inomiririra low kabhoni, inopa 304L simba regoho re0.2% ye35 KSI uye 304 ye0.2% ye42 KSI.Nechidimbu che16% kusimba uye kuderera kwe 3% kusimba kunoda kudzikisa goho 3 pakuita 0. kuseta chimiro chakaumbwa.Zviri nyore kushandisa.
