DIN2391 ST45 Chitoliro Chozizira Chojambula Chopanda Msokonezo

DIN2391 ST45 Chitoliro Chozizira Chokoka Chopanda Chitsulo Chokhala ndi Chithunzi

Kufotokozera Kwachidule:

Chitoliro chozizira chokoka chopanda chitsulo chimapangidwa kuchokera ku dzenje lopanda chitsulo.Imakonzedwanso ndikujambula kozizira pamwamba pa mandrel, kuwongolera ID, komanso kudzera mu kufa kuwongolera OD.Ma CDS ndi apamwamba kwambiri pamtunda, kulolerana kwapakati ndi mphamvu poyerekeza ndi kutentha kotsirizidwa kosasunthika. za mapulogalamu.

Kukula: 16mm-89mm.

WT: 0.8mm-18mm

Maonekedwe: Chozungulira.

Mtundu wopanga: Kuzizira kozizira kapena kukulunga kozizira.

Utali: Utali umodzi mwachisawawa / Kawiri mwachisawawa kutalika kapena ngati kasitomala akufunadi kutalika kwake ndi 10m

Annealing

Zinthu zikazizira kwambiri, machubu amaikidwa pa ng'anjo yowotchera kuti atenthetse ndikuwotcha.

Kuwongola

Pambuyo pa annealing, katunduyo amadutsa mu makina asanu ndi awiri owongoka kuti akwaniritse kuwongola koyenera kwa machubu.

Eddy panopa

Pambuyo kuwongola, chubu chilichonse chimadutsa pamakina amakono a eddy kuti azindikire ming'alu yapamtunda ndi zolakwika zina.Machubu okhawo omwe amadutsa eddy current ndi oyenera kutumizidwa kwa makasitomala.

Kumaliza

Chubu chilichonse chimapakidwa mafuta osagwirizana ndi dzimbiri kapena chopaka utoto kuti chitetezeke komanso kuti chisachite dzimbiri monga momwe makasitomala amafunira, machubu aliwonse amaphimbidwa ndi zipewa zapulasitiki kuti zisawonongeke podutsa, zolembera ndi zolemba zimayikidwa ndipo katundu wakonzeka kutumizidwa. .
