Nhanganyaya yeWelong Mandrel Bar

Tekinoroji yekugadzira

Maitiro ekugadzira mandrel bar ane akati wandei akaoma uye akajeka matanho. Yokutanga ndeyekunyunguduka kwezvinhu, izvo zvinovimbisa kufanana uye kuchena kweiyo core bar. Zvadaro kuumba, kuburikidza nekugadzira nzira, zviyo zvezvinhu zvinonatswa, nokudaro zvichivandudza maitiro ayo emagetsi uye hupenyu hwebasa. Iyo yakaumbwa mandrel inoda kurapwa kwekupisa, maitiro anobvisa kushushikana kwemukati uye anowedzera kuoma uye kupfeka kusagadzikana kweiyo mandrel. Pashure paizvozvo, machining, kusanganisira kutendeuka, milling uye mamwe mashandiro, kunoita mandrel kusangana nemagadzirirwo nemazvo zvinodiwa. Nhanho yekupedzisira ndeye kurapwa kwepamusoro, sekudzima, kupisa, nezvimwewo, kuwedzera kusimba kwekuora uye kuoma kwepasi kwe mandrel.

Kuwanda kwekushandisa uye zvakatemwa

Mandrel bar inoshandiswa zvakanyanya mumhando dzakasiyana dzezvigayo, seMPM (multi-pass rolling mill), PQF (high precision rolling mill) uye FQM (fast rolling mill). Mhando dzayo dzakasiyana-siyana, kubva pa Φ80 mm kusvika ku 500 mm muhupamhi, kureba kubva pa 2500 mm kusvika ku 17,500 mm, inogona kusangana nezvinodiwa zvakasiyana-siyana zvekugadzira.

Kusarudzwa kwezvinhu

Zvinhu zvemandrel bar zvinowanzova AISI H13 kana iyo yenyika chiyero 4Cr5MoSiV1 uye 36CrNiMoV6. Zvishandiso izvi zvine zvakanakisa tembiricha yepamusoro uye simba remagetsi kuchengetedza kugadzikana mukupisa kwepamusoro uye kudzvanywa kwenzvimbo. Izvo zvisiri-metallic inclusions mune mandrel zvinhu zvinofanirwa kunge zvisingapfuure 1.0 giredhi A, B, C uye D, uye saizi yezviyo inofanira kusvika giredhi 8 kana pamusoro. Izvi zvakaomesesa zvinhu zvinodiwa zvinovimbisa iyo yepamusoro mhando uye kuvimbika kweiyo mandrel bar.

Mechanical property

Iyo yakakurudzirwa michina ye mandrel bar yeH13 zvinhu ndeiyi: Kune iyo mandrel ine dhayamita ≤200 mm, iyo tensile simba ndeye 1127-1274 mpa, simba regoho riri ≥931MPa, kureba kuri ≥8%, chikamu shrinkage. iri ≥25%, basa rekuita ≥20J, uye kuoma kuri HB350-390; Kune mandrel ine dhayamita > 200 mm, simba rayo rekusimba i1078-1274 mpa, goho simba i ≥882MPa, elongation i ≥8%, chikamu shrinkage ≥25%, kukanganisa kushanda ≥20J, kuoma kuri HB330-375.
