Momwe mungasankhire chiŵerengero cha forging?

Pamene chiŵerengero cha forging chikuwonjezeka, ma pores amkati amaponderezedwa ndipo ma dendrites omwe amaponyedwa amathyoka, zomwe zimapangitsa kuti pakhale kusintha kwakukulu kwautali komanso kusinthasintha kwa makina a forging. Koma pamene elongation forging chigawo chiŵerengero ndi wamkulu kuposa 3-4, monga forging chigawo chiŵerengero ukuwonjezeka, zoonekeratu CHIKWANGWANI nyumba aumbike, kuchititsa kuchepa kwambiri mu plasticity index wa yopingasa makina katundu, zikubweretsa anisotropy wa forging. Ngati chiŵerengero cha gawo la forging ndi chaching'ono kwambiri, kupangira sikungathe kukwaniritsa zofunikira. Ngati ndi yayikulu kwambiri, imawonjezera kuchuluka kwa ntchito yopangira komanso imayambitsa anisotropy. Chifukwa chake, kusankha chiŵerengero choyenera cha forging ndi nkhani yofunika kwambiri, ndipo nkhani ya deformation yosagwirizana pa nthawi yolemba iyeneranso kuganiziridwa.

Chiŵerengero cha forging nthawi zambiri chimayesedwa ndi kuchuluka kwa mapindikidwe panthawi ya kutalika. Zimatanthawuza chiŵerengero cha kutalika kwa m'mimba mwake wa zinthu zomwe ziyenera kupangidwa, kapena chiŵerengero cha gawo la mtanda wa zopangira (kapena billet prefabricated) musanayambe kupangira gawo la mtanda wa mankhwala omalizidwa pambuyo popanga. Kukula kwa chiŵerengero cha forging kumakhudza makina azitsulo ndi khalidwe la forgings. Kuchulukitsa chiŵerengero cha forging ndikopindulitsa pakuwongolera ma microstructure ndi katundu wa zitsulo, koma kupangika mopitirira muyeso sikulinso kopindulitsa.

Mfundo yosankha chiŵerengero cha forging ndikusankha yaying'ono momwe mungathere ndikuwonetsetsa zofunikira zosiyanasiyana za forgings. Chiŵerengero cha forging nthawi zambiri chimatsimikiziridwa malinga ndi izi:

1. Pamene apamwamba mpweya structural zitsulo ndi aloyi structural zitsulo ndi momasuka anamanga pa nyundo: forgings mtundu kutsinde, iwo mwachindunji ananamizira ku ingots zitsulo, ndi forging chiŵerengero kuwerengedwa zochokera gawo lalikulu ayenera ≥ 3; Chiŵerengero cha forging chowerengedwa kutengera ma flanges kapena mbali zina zotuluka ziyenera kukhala ≥ 1.75; Mukamagwiritsa ntchito zitsulo zachitsulo kapena zida zogubuduzika, chiŵerengero cha forging chowerengedwa kutengera gawo lalikulu ndi ≥ 1.5; Chiŵerengero cha forging chowerengedwa kutengera ma flanges kapena mbali zina zotuluka ziyenera kukhala ≥ 1.3. Kwa mphete zopangira mphete, chiŵerengero chokonzekera chiyenera kukhala ≥ 3. Kwa ma disk forgings, amapangidwa mwachindunji kuchokera kuzitsulo zachitsulo, ndi chiŵerengero chokhumudwitsa cha ≥ 3; Nthawi zina, chiŵerengero chosokoneza chikuyenera kukhala> 3, koma chomaliza chiyenera kukhala>.

2. Nsalu yapamwamba yachitsulo yachitsulo ya billet sikuti imangofunika kuthetsa zolakwika zake, komanso imayenera kukhala ndi kugawa kofanana kwa carbides, kotero kuti chiŵerengero chachikulu cha forging chiyenera kutengedwa. Chiŵerengero cha chitsulo chosapanga dzimbiri chingasankhidwe ngati 4-6, pamene chiŵerengero cha zitsulo zothamanga kwambiri chiyenera kukhala 5-12.
