WELONG shaft forgings hombe hydro-jenareta

Forged Material:

20MnNi uye 20MnNi.

Mechanical Properties:

Kune ukuru hwekugadzira (T) pakati pe300mm <T ≤ 500mm, zvinhu 20MnNi zvinofanirwa kunge zvine simba regoho ≥ 265MPa, simba rekusimba ≥ 515MPa, kureba mushure mekutyoka ≥ 21%, kudzikiswa kwenzvimbo ≥ 35 ≥ ≥ ≥ ≥ 35% ) ≥ 30J, uye hapana kuputika panguva yekukotama kunotonhora.

Kune ukuru hwekugadzira (T) yakakura kupfuura 200mm, iyo 25MnNi inofanirwa kuve ine goho simba ≥ 310MPa, tensile simba ≥ 565MPa, elongation mushure mekutsemuka ≥ 20%, kuderedzwa kwenzvimbo ≥ 35%, kukanganisa kunyura simba 0≥3 , uye hapana kuputika panguva yekukotama kunotonhora.

Kuedza Kusina Kuparadza:

Dzakasiyana dzisiri dzekuparadza nzira dzekuyedza dzakadai seye ultrasonic kuyedza (UT), magineti yekuongorora (MT), mvura inopinda mukati meyedzo (PT), uye yekuona yekuongorora (VT) inofanirwa kuitwa munzvimbo dzakasiyana dzeiyo huru shaft forging pamatanho uye mamiriro akasiyana. .Zvinhu zvekuyedza uye maitiro ekugamuchirwa zvinofanirwa kuenderana neakakodzera zviyero.

Defect Treatment:

Kuremara kwakanyanya kunogona kubviswa nekukuya mukati memuchina wekubvumidza renji.Zvisinei, kana kudzika kwekuremara kwekubvisa kunopfuura 75% yemvumo yekupedzisa, kugadzirisa welding kunofanira kuitwa.Kugadzirisa kukanganisa kunofanira kubvumirwa nemutengi.

Shape, Dimension, uye Surface Roughness:

Iyo forging process inofanirwa kusangana nedimensional uye pamusoro roughness zvinodiwa zvinotsanangurwa mukudhirowa kweodha.Iyo yemukati denderedzwa pamusoro roughness (Ra kukosha) yekugadzira ichagadziriswa nemutengesi kuti awane 6.3um.

Kunyunguduka: Ingots dzesimbi dzekugadzira dzinofanirwa kugadzirwa kuburikidza nemagetsi kunyunguduka uye wozokwenenzverwa kunze kwechoto pamberi pekukanda vacuum.

Kugadzira: Mipiro yakakwana yekucheka inofanira kupiwa kune sprue uye riser kumagumo eingot yesimbi.Kugadzira kunofanirwa kuitwa pane anokwanisa kuforoma mashini kuti ive nechokwadi chakakwana chepurasitiki deformation yemuchinjiko-chikamu chekugadzira.Zvinokurudzirwa kuva nereshiyo yekufogisa inopfuura 3.5.Iyo yekugadzira inofanira kuswedera pedyo nechimiro chekupedzisira uye zviyero, uye iyo yepakati yekugadzira uye ingot yesimbi inofanira kuenderana zvakanaka.

Kupisa Kurapa KweZvivakwa: Mushure mekugadzira, iyo yekugadzira inofanirwa kudzikamisa kana normalizing uye kupisa kurapwa kuti uwane yunifomu chimiro uye zvivakwa.Tembiricha yekudziya shoma haifanire kunge yakaderera kupfuura 600°C.

Kana iwe uchida rumwe ruzivo nezve WELONG forgings yegiya hombe uye mhete yegiya, nemutsa tizivise.
