Hordhaca Welong Mandrel Bar

Farsamada wax soo saarka

Habka wax soo saarka ee bar mandrel ka kooban yahay dhowr tallaabo adag oo sax ah. Marka hore waa dhalaalidda walxaha, taas oo hubinaysa isku-duubnaanta iyo nadiifnimada bar-xadhigeedka. Ka dib abuurista, iyada oo loo marayo habka foornada, hadhuudhka walxaha waa la nadiifiyaa, taas oo hagaajinaysa sifooyinka farsamada iyo nolosha adeegga. Manneerka been abuurka ah wuxuu u baahan yahay daawaynta kulaylka, habka ka saaraya walbahaarka gudaha oo kordhiya adkaanta iyo xidhashada iska caabinta mandrel. Taas ka dib, mashiinada, oo ay ku jiraan leexashada, shiidaalka iyo hawlaha kale, ka dhigaysa mandrel buuxiyey shuruudaha saxnaanta design. Talaabada ugu dambeysa waa daaweynta dusha, sida deminta, xanaaqa, iwm, si kor loogu qaado caabbinta daxalka iyo adkaanta dusha sare ee mandrel.

Baaxadda codsiga iyo qeexida

Bar Mandrel waxaa si weyn loogu isticmaalaa noocyada kala duwan ee mishiinka duubista, sida MPM (multi-pass rolling Mills), PQF (dhakhso-shiid kiimikaad) iyo FQM (dhakhso u duuban). Tilmaamo kala duwan, oo u dhexeeya Φ80 mm ilaa 500 mm dhexroor, dhererka 2500 mm ilaa 17,500 mm, waxay dabooli kartaa baahiyaha wax soo saarka ee kala duwan.

Xulashada alaabta

Walxaha baarka mandrel badanaa waa AISI H13 ama heerka qaranka 4Cr5MoSiV1 iyo 36CrNiMoV6. Qalabkani waxay leeyihiin sifooyin heerkul sare oo heer sare ah iyo xoog farsamo si loo ilaaliyo xasilloonida heerkulka sare iyo jawiga cadaadiska sare. Ku darida aan biraha ahayn ee walxaha mandrel waxa looga baahan yahay in aanay ka badnayn 1.0 darajo A, B, C iyo D, cabbirka hadhuudhkuna waa inuu gaadho 8 darajo ama ka badan. Shuruudaha walxahan adag waxay xaqiijinayaan tayada sare iyo isku halaynta baarka mandrel.

Hantida makaanikada

Qalabka farsamada ee lagu taliyey ee qalabka H13 waa sida soo socota: Mashiinka leh dhexroorka ≤200 mm, xoogga xajinta waa 1127-1274 mpa, awoodda wax-soo-saarka waa ≥931MPa, dhererku waa ≥8%, qaybta hoos u dhigista waa ≥25%, shaqada saameyntu waa ≥20J, iyo adkaanta waa HB350-390; Marka loo eego mandrel dhexroorka> 200 mm, xoogga xajintu waa 1078-1274 mpa, xoogga dhalidda waa ≥882MPa, elongation waa ≥8%, hoos u dhaca qaybta waa ≥25%, shaqada saameyntu waa ≥20J, adkaanta waa HB330-375.
