Majenale a crankshaft (kuphatikiza magazini akulu ndi zolemba zolumikizira ndodo) ndi zida zazikulu zotumizira mphamvu ya injini. Mogwirizana ndi zofunikira za mtundu wa GB/T 24595-2020, kuuma kwazitsulo zomwe zimagwiritsidwa ntchito pa crankshafts ziyenera kuyendetsedwa mosamalitsa pambuyo pozimitsa ndi kutentha. Makampani opanga magalimoto apanyumba ndi apadziko lonse lapansi ali ndi miyezo yomveka bwino yovomerezeka ya kuuma kwa magazini a crankshaft, ndipo kuyezetsa kuuma ndi njira yofunika kwambiri katundu asanachoke mufakitale.
Malinga ndi GB/T 24595-2020 Steel Bars for Automobile Crankshafts and Camshafts, kuuma kwa pamwamba kwa magazini a crankshaft kudzakwaniritsa zofunikira za HB 220-280 pambuyo pozimitsa ndi kutentha.
Muyezo wa ASTM A1085 (wotulutsidwa ndi American Society for Testing and Materials, ASTM) umanena kuti kulimba kwa magazini olumikiza ndodo za crankshafts zamagalimoto onyamula anthu kudzakhala ≥ HRC 28 (yogwirizana ndi HB 270).
Kaya ndi malingaliro a mbali yopanga popewa kukonzanso ndalama ndikuteteza mbiri yabwino, wogwiritsa ntchito popewa kufupikitsa moyo wautumiki wa injini ndi zoopsa zolephera, kapena mbali yogulitsa pambuyo popewa ngozi zachitetezo, ndikofunikira kuletsa zinthu zotsika mtengo kulowa mumsika ndikuyesa kuuma kwa crankshaft molingana ndi miyezo.
Rockwell hardness tester yomwe imadziwika bwino ndi ma crankshafts opangidwa ndi kampani yathu imazindikira ntchito zodziwikiratu monga kusuntha kwa benchi ya crankshaft, kuyesa, ndi kutumiza ma data. Imatha kuchita mwachangu kuyesa kwa kuuma kwa Rockwell (mwachitsanzo, HRC) pamagawo olimba a magawo osiyanasiyana a crankshaft.
Imagwiritsa ntchito makina owongolera otsekeka amagetsi kuti athe kutsitsa ndikuyesa, woyesa uyu amakhala ndi batani limodzi (kuyandikira chogwirira ntchito, kuyika katundu, kusunga katundu, kuwerenga, ndikutulutsa chogwirira ntchito zonse zimangochitika zokha, ndikuchotsa zolakwika zamunthu).
Dongosolo la crankshaft clamping limapereka kusuntha kwamanja ndi manja kutsogolo ndi kumbuyo, ndikusuntha kumanzere, kumanja, ndi mmwamba ndi pansi, kulola kuyeza kwa malo aliwonse a crankshaft.
Chokhoma chosankha cha crankshaft chimakupatsani mwayi wodzitsekera, ndikuchotsa chiwopsezo cha kutsetsereka kwa workpiece pakuyezera.
