mea 40cr

ʻO 40Cr ka helu kila maʻamau GB ma Kina, a ʻo 40Cr ke kila kekahi o nā kila i hoʻohana nui ʻia i ka ʻoihana mīkini hana. paʻakikī i ka Ф 28 ~ 60 mm, i ka wā e hoʻopiʻi ai kaʻaila i ka Ф 15 ~ 40 mm. He kūpono hoʻi ke kila no ka cyanidation a me ka quenching kiʻekiʻe. no ka hana ʻana i nā ʻeleʻele plastik nui.

Medium carbon tempered steel, anuanu poʻomanaʻo make steel.ʻO ke kila ke kumu kūʻai haʻahaʻa, maʻalahi e hana a hiki ke loaʻa i kekahi paʻakikī, plasticity a me ke kūpaʻa abrasion ma hope o ka mālama ʻana i ka wela. e hoʻokokoke ana i ke kūlana kaulike. Hoʻohālikelike ʻia i ka 550 ~ 570 ℃, ʻoi aku ka maikaʻi o ke kila.

ʻO nā ʻāpana shaft kekahi o nā ʻāpana maʻamau i ʻike pinepine ʻia i nā mīkini. ili, conical ili, puka i loko a me ka milo a me ka ili hope e pili ana. E like me ke ano like ole o ka hale, hiki ke maheleia na mahele o ke kumu i ke kumu optic, ka step step, ka hollow shaft a me ka crankshaft.

ʻO 40Cr kahi mea maʻamau o nā ʻāpana shaft. He mea maʻalahi a hiki ke loaʻa i ka hana ʻoki ʻoi aku ka maikaʻi ma hope o ke kinai ʻana a me ka hoʻomaʻamaʻa ʻana (a i ʻole ka hoʻomaʻamaʻa ʻana), a hiki ke loaʻa i nā waiwai mechanical piha kiʻekiʻe e like me ka ikaika a me ka paʻakikī. Ma hope o ke kinai ʻana, hiki i ka paʻakikī o ka ʻili ke hiki i 45 ~ 52HRC.

Hoʻohana nui ʻia ʻo 40Cr i ka hana mechanical. ʻO kēiaʻano kila he mauʻano mechanical maikaʻi. ʻO kēia ke kila kalapona kalapona me ka hana hoʻopiʻi maikaʻi, hiki i ka 40Cr ke hoʻopaʻakikī i ka HRC45 ~ 52. No laila, inā pono e hoʻomaikaʻiʻia ka paʻakikī o kaʻili a me nāʻoihana mechanical kiʻekiʻe o 40Cr. e lawe ʻia i loko o ka pāʻani, hana pinepine ʻia ka mālama ʻana i ka quenching kiʻekiʻe ma hope o ke kau ʻana o 40Cr, me ka paʻakikī a hiki i 55-58hrc, no laila e loaʻa ai ka paʻakikī o ka ʻili kiʻekiʻe a mālama i ka paʻakikī maikaʻi o ka puʻuwai.
