Paunenge uchigadzira mukufa kunofambira mberi, iyo workpiece kudzvanywa, kudzvanya mamiriro uye kutanga zvinhu zvinokanganisa kugona kuwana yakagadzikana yekudhirowa mhinduro pasina wrinkles.
Mubvunzo: Isu tinogadzira mukombe mu304 simbi isina tsvina.Pachiteshi chekutanga chefa inofambira mberi, tinokwevera kune inenge 0.75 inches kudzika.Pandinotarisa ukobvu hwebutt flange perimeter, inogona kusiyana ne 0.003 inches kubva kune rimwe divi kuenda kune rimwe.Kurova kwega kwega kwakasiyana uye hakuoneki munzvimbo imwechete.Ndakaudzwa kuti ine chekuita nekugadziriswa kweiyo mbishi, pamwe kumucheto kwekunze kweiyo main spool.Tingawana sei kapu yechimiro chenguva dzose pasina macrease?
A: Ndiri kuona kuti mubvunzo wako unobvunza mibvunzo miviri: yekutanga ndiyo misiyano yaunowana mukuita kudhirowa, uye chechipiri ndiko kwakabva zvinhu uye kutsanangurwa kwayo.
Dambudziko rekutanga kukanganisa kwakakosha mukugadzirwa kwechishandiso, saka ngatiendei pamusoro pezvakakosha.Periodic kuunyana uye kuchinjika kwehukobvu pamukombe flanges mushure mekutambanudza kunoratidza kusakwana maturusi ekubatanidza muchiteshi chako chinofambira mberi chekutambanudza.Ndisingaone dhizaini yako yekufa, ndaizofanira kufunga kuti punch uye kufa radii uye kubvumidzwa kwavo kwakasiyana kunosangana ese akajairwa dhizaini paramita.
Munguva yekudhirowa maitiro, iyo workpiece inobatwa pakati peiyo yekudhirowa kufa uye mupendero inobata, nepo iyo yekudhirowa punch inokwevera zvinhu mudhirowa kufa, ichidhonza pamwe neradius yekudhirowa kuti igadzire goko.Kukweshana kwakasimba kunoitika pakati pe mold nemubati we workpiece.Munguva iyi, zvinhu zvinoiswa pasi pekudzvanyirira kwakachinjika, izvo zvinokonzeresa kuunyana uye radial elongation sezvo chibatiso chemupendero chinomisa kuyerera kwechinhu.Kana chisimbiso chekuisa chisimbiso chakanyanya kukwirira, zvinhu zvinoputika pasi pesimba rekudhonza re punch.Kana yakanyanya kuderera, makwinya achaonekwa.
Kubudirira kudhirowa kushanda hakugone kudarika muganhu pakati pegoko dhayamita uye workpiece dhayamita.Muganhu uyu unoenderana neperesenti yekuwedzera kwezvinhu.Mutemo mukuru ndewokupenda 55% kusvika 60% nguva yekutanga uye 20% nguva imwe neimwe mushure mezvo.Pamusoro pemuonde.1 inoratidza chimiro chemaitiro ekuverenga preform pressure inotarisirwa kutambanudza (Ini nguva dzose ndinowedzera zvishoma 30% simba rakawedzerwa sechinhu chekuchengetedza. Izvi zvinogona kuderedzwa kana zvichidiwa, asi zvakaoma kuwedzera mushure mekugadzirwa kwapera).
Iyo billet pressure p ndeye 2.5 N / mm2 yesimbi, 2.0-2.4 N/mm2 yemhangura alloy uye 1.2-1.5 N/mm2 yealuminium alloy.
Misiyano mukukobvu kweflange inogonawo kuratidza kuti dhizaini yako haina kusimba zvakakwana.Iyo mold bhutsu inofanirwa kuve yakakora zvakakwana kuti ikwanise kutsungirira kusagadzikana pasina kukotama.Chitsigiro chiri pasi peshangu chinofanira kunge chiri chesimbi yakasimba, uye mapini emutungamiri wezvishandiso anofanira kunge akakura zvakakwana kudzivirira kufamba kwemashure kwepamusoro uye pasi pasi panguva yekutambanudza.
Tarisawo nhau dzako.Kana iwo madhairekitori enhau akasakara uye akasununguka, haubudirire, kunyangwe maturusi ako akasimba sei.Tarisa iyo pusher yekutsikisa kuti uone kuti yakarurama uye yakaenzana nehurefu hwemutsindo wekutsikisa.Ita shuwa kuti lubricant yako yekudhirowa yakasefa uye iri muchimiro chakanaka, uye kuti chishandiso chiri kushandisa iyo chaiyo huwandu uye chaiyo nozzle chinzvimbo.Ese maturusi ekudhinda anotariswa zvakanyatsonaka kuti ave nechokwadi chepamusoro pekupedzisira, kuvhara uye symmetry.Uye nyatso teerera kudhirowa radii, ivo vanofanirwa kuve negeometry yakakwana uye kuchena kwepasi.
Zvakare, nepo vatengi vachifunga kuti 304L uye yakajairwa 304 zvinochinjika, 304L ndiyo yakanakisa sarudzo yekutambanudza.L inomirira low carbon, iyo inopa 304L 0.2% goho simba re35 KSI, ukuwo 304 ine 0.2% yegoho simba re42 KSI.Iine 16% yakaderera goho resimba, 304L inoda simba shoma kutsveyamisa uye kubata mold panguva yekuumbwa.Zviri nyore kushandisa.
