Kune nzira dzakawanda dzakasiyana mukugadzira simbi. Kazhinji, mabheti esimbi anopisa uye anonyoroveswa, zvichiita kuti kushandiswa kwesimbi kuve nyore uye kunatsiridza michina yezvikamu. Mamwe maitiro anoumbawo simbi patembiricha yekamuri.
Ngatitarisei zvakanakira nekuipira kwekukunguruka kunopisa, kutenderedza kutonhora, musoro unopisa, uye musoro unotonhora, tichitarisa mashandisiro azvo mumasimbi esimbi asina tsvina, alloy fasteners, uye maumbirwo akaumbwa.
Chii chinonzi Hot Rolling?
Patembiricha yemumba, simbi yakaoma kukanganisa uye kugadzira. Zvisinei, kana billet ichipisa uye yakanyoroveswa isati yakunguruka, nzira yacho inova nyore zvikuru-iyi inonzi hot rolling.Hot rolling ine zvikomborero zvakawanda. Kutanga, kutonhora kwakanyanya kunopfavisa simbi, zvichiita kuti zvive nyore kushandura chimiro chayo uye kunatsa zviyo zvayo, nokudaro kuwedzera maitiro ayo emagetsi. Pamusoro pezvo, kuremara kwemukati senge mabubbles, kutsemuka, uye porosity zvinogona kubatanidzwa pamwe chete pasi pekupisa kwakanyanya uye kumanikidzwa. Izvi zvinoitainopisa-yakakungurutswasimbi isina tsvinayakanakira zvimiro zvekushandisa zvinoda kuvandudzwa kusimba uye durability.Zvisinei, inopisa kukungurutswa inewo zvayakaipira. Izvo zvisina kuchena zvakatanga kuiswa musimbi zvinogona kudzvinyirirwa kuita zvidimbu zvitete pane kubatanidza nesimbi, zvichiita kuti delamination. Nokufamba kwenguva, izvi zvinogona kukonzera kutsemuka nekutsemuka, zvichikanganisa kusimba kwesimbi. Uyezve, panguva yekutonhodza mushure mekukunguruka, kutonhodza kusina kuenzana pakati pezvikamu zvemukati nekunze zvinogona kukonzera deformation, kusasimba kwekuneta, uye kumwe kukanganisa.
Chii chinonzi Cold Rolling?
Cold rolling kazhinji inoreva kushandisa simba rekunze kusimbi patembiricha yemumba kuti iite kuti isvike pahukobvu chaihwo. Nekudaro, hazvina kunaka kufunga kuti kupisa kutenderedza kunosanganisira kudziyisa nepo kutonhora kukunguruka kusingaiti. Zvichienderana nezvakagadzirwa, kutonhora kutenderedza kunogona kusanganisira kumwe kudziyisa. Musiyano wakakosha ndewekuti kana kugadzirisa kunoitika pazasi tembiricha yerecrystallization, inoonekwa sechando ichikunguruka; kana iri pamusoro, inopisa rolling.The zvakanakira kutonhora kukunguruka zvinosanganisira kukurumidza kukurumidza, kugadzirwa kwepamusoro, uye kugona kuchengetedza coating kuperera. Cold rolling inogonawo kugadzira akasiyana-siyana-muchinjika maumbirwo kuti asangane nezvinodiwa zvakasiyana-siyana zvekushandisa uye kuvandudza deformation yepurasitiki yesimbi. Cold-rolled alloymashizha esimbiuye nemazvosimbi isina tsvinaanoshandiswa zvakanyanya muaerospace, mota, uye maindasitiri emagetsi uko dimensional accuracy uye surface quality yakakosha.Zvisinei, kusara kwemukati kushushikana musimbi inotonhora-inoputirwa kunogona kukanganisa simba rose kana renzvimbo. Pamusoro pezvo, zvinhu zvinotonhora-zvakakungurutswa zvinowanzove nehupamhi hutete uye hudiki hwekutakura mutoro.
Chii chinonzi Cold Heading?
Cold heading, inonziwo cold forming, inzira yekuti simbi inoumbwa kuita imwe fomu mukati medhisi nekuisa simba rekuita pasina kudziyisa. Cold heading inopa zvakati wandei. Sezvo iyo billet yakanyatso kudzvanywa mufa, pane zvishoma kune marara ekutapa panguva yekugadzira. Inogonesawo kugadzira otomatiki, inoshandisa simba shoma sezvo pasina kudziyisa kunodiwa, uye inobvisa kudiwa kwemaitiro ekutonhora, kuita kuti kugadzira nekukurumidza uye kuderedza mitengo. Izvi zvinoita kutonhora-musorofastenerszvakaita semabhaudhi esimbi asina tsvina, nzungu, uye rivets zvinonyanya kushanda pakugadzirwa kwehuwandu nemararamiro mashoma.Zvisinei, mamwe mabasa emusoro anotonhora haagoni kupedzwa mune imwe nhanho. Panzvimbo iyoyo, iyo workpiece inofanirwa kuwedzeredzwa zvishoma nezvishoma mukufa kwakasiyana, ichida matanho akati wandei kuti uwane chimiro chaunoda. Pamusoro pezvo, zvinhu zvinoshandiswa pakutonhora musoro hazvigone kuoma zvakanyanya.
Chii chinonzi Hot Heading?
Kupisa musoro inzira iyo simbi inotanga kupisa uye kunyoroveswa, yobva yaremara mupurasitiki uchishandisa impact force.Hot heading inogona kuvandudza zvakanyanya chimiro chemukati uye mechanical properties yesimbi, ichiwedzera simba rayo uye plasticity. Iyo zvakare inoderedza kuoma kwekugadzirisa uye inowedzera kugadzirwa kwehunyanzvi. Hot-headed alloy steel fasteners anoshandiswa zvakanyanya mumaapplication anoda simba rakawanda, senge aerospace, anorema muchina, uye kuvaka.Zvisinei, kupisa musoro kunoda mari yakawanda mukudziya midziyo uye simba, zvichiita kuti kugadzirwa kwayo kudhura zvakanyanya kudarika kutonhora musoro.
Nekunzwisisa zvakanakira uye zvisingakwanisi zveaya masimbi ekugadzira matekiniki, vagadziri vanogona kusarudza yakanyatsokodzera nzira .
