Njira yoyesera kuuma kwa Rockwell ya 40Cr, 40 chromium

Pambuyo pozimitsa ndi kutenthetsa, chromium imakhala ndi mphamvu zabwino kwambiri zamakaniko komanso kulimba bwino, zomwe zimapangitsa kuti nthawi zambiri igwiritsidwe ntchito popanga zomangira zolimba kwambiri, mabearing, magiya, ndi ma camshaft. Mphamvu zamakaniko ndi kuyesa kuuma ndizofunikira kwambiri pa 40Cr yozimitsa ndi kutenthetsa.

Kuyesa kuuma kwa 40Cr nthawi zambiri kumagwiritsa ntchito njira yoyesera kuuma kwa Rockwell ndi njira yoyesera kuuma kwa Brinell poyesa. Chifukwa choyesa kuuma kwa Rockwell ndi chachangu komanso chosavuta kugwiritsa ntchito, nthawi zambiri makasitomala amakonda kugwiritsa ntchito. Pazigawo zazing'ono kapena zigawo zomwe zimafuna kulondola kwambiri, choyesa kuuma kwa Vickers chingagwiritsidwenso ntchito.

Kawirikawiri, kuuma kwa Rockwell kwa 40Cr pambuyo pozimitsa ndi kutenthetsa nthawi zambiri kumafunika kukhala pakati pa HRC32-36, kotero kuti ikhale ndi mphamvu zambiri komanso kukana kutopa.

Zotsatirazi ndi zida zoyesera kuuma kwa Rockwell zomwe zimagwiritsidwa ntchito kwambiri:

1. Chiwonetsero chamagetsi cha digito chowonjezera kulemera kwa Rockwell: cholondola, chodalirika, cholimba, komanso chogwira ntchito bwino kwambiri poyesa; chiwonetsero cha digito chimatha kuwerenga mwachindunji mtengo wa Rockwell wolimba, kapangidwe ka makina kamakonzedwa bwino, ndipo masikelo ena a Rockwell amatha kufananizidwa mwanjira ina. Chimagwiritsa ntchito ukadaulo wamagetsi wodziyimira pawokha wokweza ndi kutsitsa kuti athetse zolakwika za anthu. Dongosolo la spindle limagwiritsa ntchito kapangidwe ka spindle kopanda kukangana kuti liwongolere kulondola kwa mphamvu yoyesera yoyamba.

2. Chowunikira cha digito cha Rockwell chowunikira kuuma: kugwiritsa ntchito chophimba cha mainchesi asanu ndi atatu, mawonekedwe osavuta kugwiritsa ntchito; mphamvu yoyesera yamagetsi, kulephera kochepa, mayeso olondola kwambiri, amatha kusunga deta 500 payokha, kuzimitsa popanda kutayika kwa deta, mogwirizana ndi ISO, ASTM E18 ndi miyezo ina.

3. Choyesera kuuma cha Rockwell chokha chokha: mphamvu yoyesera kukweza mphamvu zamagetsi imagwiritsidwa ntchito kukonza kulondola kwa mphamvu, kudina kamodzi kokha kuti amalize njira yonse yoyesera kuuma, yosavuta komanso yothandiza; nsanja yayikulu kwambiri yoyesera, yoyenera kwambiri kuzindikira kuuma kwa ntchito yayikulu; yokhala ndi cholumikizira choyendetsera mwachangu mota ya servo kuti isinthe malo oyesera; deta imatha kutumizidwa ku kompyuta kudzera pa RS232, Bluetooth kapena USB.
