Crankshafts anoshandiswa zvakanyanya mumainjini.Parizvino, zvigadzirwa zveinjini dzemotokari zvinonyanya ductile iron uye simbi.Nekuda kwekuita kwakanaka kwekucheka kweiyo ductile iron, kurapwa kwakasiyana-siyana kwekupisa uye kurapwa kwepamusoro kunoitwa kuvandudza simba rekuneta, kuoma uye kupfeka kuramba kwe crankshaft.Ductile iron crankshafts ine mutengo wakaderera, saka ductile iron crankshafts yakashandiswa zvakanyanya kumba nekune dzimwe nyika.Pazasi isu tichaunza tekinoroji yekugadzira crankshaft.
Crankshaft kugadzira tekinoroji:
1. Kukandira tekinoroji ye ductile iron crankshaft
A. Kunyungudutsa
Kutorwa kwepamusoro-tembiricha, yakaderera-sarufa, yakachena yakanyungudutswa simbi ndiyo kiyi yekugadzira yemhando yepamusoro ductile iron.Midziyo yekugadzira mudzimba inonyanya kuenderana nekapu, uye simbi yakanyungudutswa haina pre-desulfurized;yechipiri ndeyepamusoro-kuchena yenguruve iron uye yakashata coke quality.Parizvino, nzira yekunyungudutsa kaviri-yekunze pre-desulfurization yakagamuchirwa, iyo inoshandisa kapu kunyungudutsa simbi yakanyungudutswa, inoibvisa kunze kwechoto, uye yobva yapisa uye inogadzirisa kuumbwa muchoto chekupinza.Parizvino, kuwonekwa kwemidziyo yesimbi yakanyungudutswa yemumba kwave kuchiitwa pachishandiswa vacuum yakananga kuverenga spectrometer.
B. Modelling
Iyo yekufemerwa kwemhepo yekuumba maitiro iri pachena yakakwira kune yevhu jecha mhando maitiro, uye yakakwirira-chaiyo crankshaft castings inogona kuwanikwa.Iyo jecha mold inogadzirwa neiyo maitiro ine hunhu hwekusina rebound deformation, iyo inonyanya kukosha kune yakawanda-inotendeuka crankshaft.Parizvino, vamwe vanogadzira crankshaft muChina vakaunza mafambiro ekufambisa kwemhepo kubva kuGermany, Italy, Spain nedzimwe nyika.Nekudaro, vashoma vanogadzira chete ndivo vakaunza mutsara wese wekugadzira.
2. Kugadzira tekinoroji yesimbi crankshaft
Mumakore achangopfuura, akati wandei emhando yepamusoro yekugadzira michina yakaunzwa muChina, asi nekuda kwenhamba shoma, yakasanganiswa nekugadzira mold tekinoroji uye zvimwe zvivakwa, mimwe michina yepamberi haina kuita basa rayo.Kazhinji, kune akawanda ekare ekugadzira michina inoda kugadziridzwa uye kuvandudzwa.Panguva imwecheteyo, tekinoroji yekudzokera kumashure uye michina ichine chinzvimbo chikuru, uye tekinoroji yepamberi yakashandiswa asi haisati yapararira.
3. Mechanical processing technology
Parizvino, mitsetse yakawanda yekugadzira crankshaft inoumbwa neyakajairwa muchina maturusi uye akakosha maturusi emuchina, uye kugona kwekugadzira uye otomatiki kwakadzikira.Iyo roughing midziyo inonyanya kushandisa multi-tool lathe kushandura crankshaft main journal uye mutsipa, uye kugadzikana kwemhando yemaitiro kwakashata, uye zviri nyore kugadzira kushushikana kukuru kwemukati, uye zvakaoma kuwana zvine musoro.Machiningmvumo.Kupedzwa kwakazara kunoshandisa crankshaft kugaya michina yakadai seMQ8260 yekukuya - semi-kupedza - kugaya zvakanaka - kupukuta, kazhinji nekushanda kwemaoko, uye mhando yekugadzira haina kugadzikana.
4. Kurapa kwekupisa uye pamusoro pekusimbisa kurapa tekinoroji
Iyo yakakosha tekinoroji yekupisa kurapwa kwe crankshaft ndeyekusimbisa kurapa kwepamusoro.Ductile iron crankshafts inowanzogadziriswa uye yakagadzirirwa kugadzirira pamusoro.Mishonga yekusimbisa kumeso inowanzo shandisa induction kuomesa kana nitriding.Forged steel crankshafts inonyorwa uye yakatenderedzwa.Midziyo inotengeswa kunze kwenyika inosanganisira AEG otomatiki crankshaft quenching muchina uye EMA quenching muchina.
Wuxi inotungamira Precision Machinery Co., Ltdinopa vatengi veese saizi yakakwanatsika yekugadzira simbi masevhisinemaitiro akasiyana.
