Copper bushing centrifugal casting

Iyo centrifugal casting tekinoroji yemhangura bushings inzira inoshanda uye yakanyatso kukanda nzira, iyo inoshandiswa zvakanyanya mukugadzirwa kwemhangura alloy bushings inoshandiswa mumichina michina, mota, migodhi nemimwe michina inorema. Nheyo yekutanga yekukanda centrifugal ndeye kushandisa simba re centrifugal rinogadzirwa ne-high-speed inotenderera mold kugovera zvakaenzana mvura yesimbi kumadziro emukati emuumbi, zvichiita kuti iite yakakwirira-density uye yakanaka-kuita kukanda.

Nheyo yekutanga ye centrifugal casting tekinoroji

Centrifugal casting ndeyekudira mvura yesimbi yakanyunguduka muforoma inotenderera, kusundira mvura yesimbi kumadziro eforoma nesimba repakati, uye pakupedzisira kuita kukanda kwakasimba. Munguva yekukanda, nekuda kwekuita kwe centrifugal simba, kuwanda kwemukati nekunze kwezvikamu zvekukanda kwakasiyana. Iyo yekunze dhizaini iri padyo nemadziro ekuumbwa, ayo anowanzo gadzira yakawedzera compact uye dense chimiro, uye iyo yemukati layer yakasununguka, iyo yakakodzera kugadzira castings ine yakakosha yemuviri zvinhu.

Centrifugal casting process yemhangura bushings

Copper bushings inowanzogadzirwa nemhangura alloy zvinhu. Iyo centrifugal casting process inonyanya kusanganisira anotevera matanho:

1. Kugadzirira Mold Iyo mold inowanzogadzirwa nepamusoro-simba refractory zvinhu, izvo zvinogona kumira kutonhora kwepamusoro uye kuramba yakasimba panguva yekutenderera. Rusvingo rwomukati rwe mold inogona kugadzirwa muchimiro chebushing.

2. Metal kunyunguduka Mushonga wemhangura unodziiswa kusvika pakunyunguduka, kazhinji muchoto chekupisa, uye tembiricha yekunyunguduka inowanzova pakati pe1050°C ne1150°C.

3. Dururirai simbi yakanyungudutswa Simbi yakanyungudutswa inodirwa muchiumbwa chinotenderera kuburikidza nedziva rakanyungudutswa. Iyo yekutenderera kumhanya kwe mold inowanzodzorwa pamakumi kusvika kumazana ekuchinja paminiti, uye kumhanya kwekutenderera kunobata zvakananga kunaka uye chimiro chekukanda.

4. Kutonhodza nekuomesa Simbi yakanyungudutswa inoomesa muforoma nekuda kwekutonhodza. Nekuda kwekuita kwesimba re centrifugal, simbi yakanyungudutswa yakagoverwa zvakaenzana, ichiita madziro ekunze akareba, nepo madziro emukati akasununguka.

5. Kugadzirisa uye kuongorora Mushure mokunge kukanda kwatonhora, mold inomira kutenderera, kupeta uye kuongororwa kunofanirwa kunoitwa kuti ive nechokwadi chokuti bushing yemhangura inosangana nehukuru uye hutano hunodiwa.

Zvakanakira zve centrifugal kukanda mhangura bushings

Yakakwira density uye yakakwira simba: Centrifugal casting inogona kuita iyo yekunze layer yekukanda dense kuburikidza ne centrifugal simba, uye ine yakakwira mechanic zvivakwa.

1. Mashoma ekukanda kukanganisa: Centrifugal casting inoderedza chizvarwa chekuremara senge pores uye inclusions, uye inovandudza kunaka kwekukanda.

2. Kuramba kwakanaka kupfeka: Copper alloy bushings inowanzo shandiswa kukurira kupesana kukuru. Centrifugal casting tekinoroji inoita kuti kuomarara kwepamusoro kweiyo castings kukwidze uye kuramba kwekupfeka kuri nani.

3. High molding precision: Centrifugally cast copper bushings inogona kunyatso kudzora ukuru uye chimiro, kuderedza basa rekugadzirisa.

Zvishandiso zvinoshanda

Copper alloy zvinhu zvinowanzoshandiswa kukanda centrifugal zvinosanganisira:

Kanda mhangura (yakadai semhangura-tin alloy, copper-lead alloy)

Kanda bronze (yakadai sebronze, aluminium bronze)

Aluminium bhuronzi, aya alloys ane yakanaka corrosion resistance uye kupfeka kuramba, akakodzera kushandiswa sebushing zvinhu.

Nzvimbo dzekushandisa

Iyo centrifugal casting tekinoroji yemhangura bushings inowanzo shandiswa kugadzira yakakwirira-inoshanda bushings, mabhengi, masiraidhi uye zvimwe zvikamu, uye inoshandiswa zvakanyanya mu:

Mechanical midziyo: senge kubereka bushings mumakina ekufambisa michina.

Indasitiri yemotokari: Mabhiza anoshandiswa kumainjini emotokari, magiya mabhokisi uye zvimwe zvikamu.

Midziyo yekuchera migodhi: Inoshandiswa kune zvikamu zvinoda kupfeka kwakanyanya mumichina yemigodhi.

Kufurira kwemaitiro parameters

Kutenderera kumhanya: Iyo yekutenderera inomhanyisa inotarisa kufanana kwesimbi yekugovera mvura uye kuwanda kwekukanda. Kunyanya kukwira kana kuderera kunokanganisa kunaka kwekukanda.

Tembiricha yeMetal liquid: Tembiricha yakadzikira yesimbi inogona kutungamira kumvura yakashata, nepo tembiricha yakawandisa inogona kukonzera oxidation uye mamwe matambudziko nyore.

Kutonhora kwekumhanya: Iyo yekutonhora inomhanya inokanganisa iyo microstructure yekukanda. Kukurumidza kana kunonoka kunokanganisa kushanda kwebhushi remhangura.

Muchidimbu, iyo centrifugal yekukanda tekinoroji yemhangura bushing inzira inoshanda kwazvo yekugadzira. Inogona kuburitsa copper alloy bushings ine yakanakisa mechaniki zvivakwa, yakakwirira dimensional kurongeka uye yakatsetseka pamusoro. Iyo yakanakira nzira yekugadzira kune akawanda epamusoro-kuita mamechani zvikamu.
