Basic maitiro ekuvaka michina castings

Material uye kuumbwa maitiro
Zvishandiso zvinowanzoshandiswa: Grey cast iron (yakadai seHT200-HT300) ndiyo inonyanya kushandiswa, uye mamwe makiyi anotakura zvikamu anogadzirwa nesimbi yakakandwa, inosangana nemitemo yenyika yakadai seGB9439-88.

Zvakanakira magadzirirwo egirafu: Pepa kana kuti spherical graphite mune grey cast iron inopa kusakara kwakanaka, kubatwa nekuvhunduka uye kugona kuzvizora-uye inokodzera{1}}kuremerwa uye kuzunguzika kwenzvimbo.

High carbon equivalent design: Pedyo ne eutectic composition, yakaderera kunyungudika, mvura yakanaka, nyore kugadzira matete-zvivakwa zvine madziro.

Chimiro uye geometric features
Chimiro chakaomarara: Inogona kugadzira zvimiro zvakaoma senge mukati megomba, nzvimbo dzakakomberedzwa, mbabvu mahwendefa, nezvimwe, senge track fremu, rocker maoko, mabhesi, nezvimwe.

Huwandu hwakasiyana-siyana hwehukuru uye huremu: Kubva pamakumi emakirogiramu kusvika kumakumi ematani, kusangana nezvinodiwa zvezvicherwa zvidiki kusvika kumichina mikuru yenhoo.

Ukobvu hwemadziro husina kuenzana: Panowanzo siyana mukukora, izvo zvinogona kutungamira kune kusaenzana kusimba uye shrinkage, uye hurema hunoda kudzorwa nekusimuka, simbi inotonhora kana sequential solidification process.

Maitiro uye maitiro ekugadzira
Mainstream process: Kunyanya shandisa resin jecha kukanda kana kurasika furo kukanda, uchifunga nezve chaiyo uye mutengo.

Kurapa kwekupisa kunowanzoitika: Kukanda mahombe kunowanzoita kushushikana-kuregedzerwa kunyura (550–600 degree) kana kuchembera nemaoko kuderedza kushushikana kwasara uye kunatsiridza kugadzikana kwedimensional.

Kuderera kushoma maitiro: Precision castings iri padyo nechimiro chekupedzisira, ichidzikisa machining mvumo nekuvandudza mashandisirwo emidziyo.

Kuita uye kushandiswa maitiro
Mechanical properties :
Kusimba kwesimba: HT250 Yakakura kudarika kana yakaenzana ne250 MPa, HT300 Yakakura kudarika kana yakaenzana ne300 MPa;

Iko kuomarara kwakadzikira, uye basa rekuita rinowanzo <10 J, iyo isingakodzeri chikamu chepakati cheyakanyanya kukanganisa mutoro.

Functional Advantages :
Kuramba kwakanaka kupfeka: Graphite mafuta ekuchengetedza uye kuderedza friction;
Excellent shock absorption: Iyo yekunyorovesa kuita iri nani pane iyo yesimbi, yakakodzera kune yakakwira vibration michina;

High rigidity: tsigira zvimiro zvakakura kuti ive nechokwadi chechokwadi chemuchina wese.
