Hino Fuso Universal Kumbuyo Bolt

1, Spheroidizing annealing ya mabawuti amphamvu kwambiri

Pamene ma bolts a hexagon socket head bolts amapangidwa ndi njira yoziziritsira mutu, kapangidwe koyambirira kachitsulo kadzakhudza mwachindunji luso lopanga panthawi yozizira.Choncho, chitsulocho chiyenera kukhala ndi pulasitiki yabwino.Pamene mankhwala zikuchokera zitsulo mosalekeza, kapangidwe metallographic ndi chinthu chofunika kudziwa plasticity.Nthawi zambiri amakhulupirira kuti pearlite yowoneka bwino sithandiza kupanga mutu wozizira, pomwe pearlite yabwino yozungulira imatha kupititsa patsogolo luso la pulasitiki lachitsulo.
Kwa sing'anga mpweya zitsulo ndi sing'anga mpweya aloyi zitsulo ndi kuchuluka kwa zomangira mkulu-mphamvu, spheroidizing annealing ikuchitika pamaso kuzizira mutu, kuti apeze yunifolomu ndi zabwino spheroidized pearlite kuti akwaniritse zosowa zenizeni kupanga.

2, Kuponyera ndi kutsika kwa mabawuti amphamvu kwambiri

Njira yochotsera mbale ya iron oxide ku ndodo ya waya yachitsulo yozizira ndiyo kuvula ndi kutsika.Pali njira ziwiri: makina descaling ndi pickling mankhwala.Kusintha njira ya pickling mankhwala a waya ndodo ndi mawotchi descaling kumawonjezera zokolola ndi kuchepetsa kuipitsa chilengedwe.Njira yochepetserayi imaphatikizapo njira yopindika, kupopera mbewu mankhwalawa, ndi zina zotero. Kutsika kwachitsulo ndikwabwino, koma sikelo yotsalira yachitsulo sichingachotsedwe.Makamaka pamene sikelo ya chitsulo okusayidi sikelo ndi amphamvu kwambiri, kotero mawotchi descaling amakhudzidwa ndi makulidwe a sikelo chitsulo, dongosolo ndi mkhalidwe nkhawa, ndipo ntchito mu carbon zitsulo waya ndodo kwa otsika mphamvu fasteners.Pambuyo potsitsa mawotchi, ndodo ya waya ya zomangira zolimba kwambiri imadutsa njira yothira mankhwala kuti ichotse masikelo onse a iron oxide, ndiko kuti, kutsika kwapawiri.Kwa ndodo za waya wa carbon zitsulo zotsika, chitsulo chosiyidwa ndi makina ocheperako chikhoza kupangitsa kuti pakhale kusalinganika kwa kukonza mbewu.Pamene bowo la njere limamatira ku pepala lachitsulo chifukwa cha kukangana kwa ndodo ya waya ndi kutentha kwa kunja, pamwamba pa ndodo ya waya kumatulutsa zizindikiro zotalika.
