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 ye blank, mutsauko kubva kune rumwe rutivi kusvika kune rumwe rutivi unogona kunge wakakwirira se 0.003 inches.Kurova kwese kwakasiyana uye hakuoneki mune imwe nzira yave yakataurwa pamusoro pechinhu chimwe chete, zvichida chave chakataurwa pamusoro pechinhu chimwe chete. iyo huru coil.Tingawana sei mukombe wakaumbwa unoramba uchiwunyana?
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, chivharo chinobatwa pakati pechidhirowa chinofa uye chibatiso chisina chinhu, ukuwo chibhakera chinodhirowa chinokwevera zvinhu mudhirowa kufa, chichiikwevera ichitenderedza radius yekudhirowa kuti iite goko. Pane kupesana kwakawanda pakati pekufa nemubati asina chinhu. Panguva iyi, zvinhu zvinodzvanywa nechemberi, ndicho chikonzero chekuunyana uye kurebesa kweradial kuyerera kwechinhu chisina kuvharwa, kana kuyerera kwechinhu chisina kuvharwa kunopesana nekuyerera kwechinhu chisina chinhu. stretch punch.Kana yakanyanya kuderera, kuunyana kuchaitika.
Pane muganhu pakati peshell diameter uye dhayamita isina chinhu isingagoni kudarika kuti ibudirire kudhirowa kushanda.Muganho uyu unosiyana nepercent elongation yezvinhu.Mutemo mukuru ndeye 55% kusvika 60% yekutanga kudhirowa uye 20% kune imwe neimwe inotevera kudhirowa. 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 chigadzirwa chako chekugadzira hachina kusimba zvakakwana.Bhutsu dzako dzekuumbwa dzinofanira kunge dzakakora zvakakwana kuti dzimire kudhonza pasina buckling.Chitsigiro chiri pasi peshangu inofa chinofanira kunge chiri simbi yakasimba, uye mapini anofa anofanira kunge akakura zvakakwana kudzivirira chero lateral kufamba kwepamusoro uye pasi kunofa panguva yekutambanudza.
Onawo 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. Iva nechokwadi chekuti mafuta ako ekudhirowa akanyatsopepetwa uye akachengetedzwa, uye kuti vhoriyamu yekushandisa uye nzvimbo yemuromo zvakagadziriswa.Kunyatso dhinda uye kunyatsoongorora kudhirowa. radii;geometry yavo uye kupera kwepamusoro kunofanirwa kuve kwakakwana.
Zvakare, nepo vatengi vachiwanzoona 304L uye standard 304 seinochinjika, iyo 304L ndiyo sarudzo iri nani yekudhirowa.L inomiririra low kabhoni, iyo inopa 304L goho resimba re0.2% ye35 KSI uye 304 ye0.2% ye42 KSI.Nechidimbu chegumi nenhatu chega chega chega chega chega chega chega chega chega chega chega chega chega uye 304 % simba rekuita. Zviri nyore kushandisa.
