Ndedzipi Nzira dzekuve nechokwadi uye Kuvandudza Machining Kurongeka?
1) Mhosho yekudzivirira tekinoroji: kushandisa zvine musoro kwehunyanzvi tekinoroji uye zvishandiso kudzikisa zvakananga yekutanga kukanganisa kutamisa kukanganisa kwepakutanga kukanganisa kwepakutanga homogenization yekutanga kukanganisa.
2) Kukanganisa kubhadharira tekinoroji: pamhepo kutariswa kweotomatiki kuenzanisa mill inoshanda kutonga kweyekuita basa rekukanganisa zvinhu.
- Chii chinoitaMachiningpamusoro geometry inosanganisira?
Geometric roughness, surface corrugncy, texture direction, surface defects.
-Ndezvipi zvemuviri uye zvemakemikari zvimiro zvepasi layer zvinhu?
1) Cold basa kuomesa pamusoro pamusoro layer simbi
2) Metallographic deformation yepamusoro simbi simbi
3) Residual stress of surface layer metal
-Edza kuongorora izvo zvinokanganisa machining pamusoro roughness?
1) Iko roughness kukosha kunosanganisira: kureba kwenzvimbo yakasara yekucheka.
2) Zvinhu zvikuru: tip arc radius, main deflection Angle, deflection Angle feed
3) Chechipiri zvinhu: kuwedzera kumhanya kwekucheka, kusarudza mvura yekucheka zvakakodzera uye kuwedzera rake Angle yechishandiso kuvandudza kunaka kwekukuya kwechishandiso.
-Ongorora zvinhu zvinokanganisa kushata kwepamusoro kwekukuya.
1) Geometric factor: pesvedzero yehuwandu hwekukuya pahukukutu hwepamusoro
2) Pesvedzero yekukuya vhiri granularity uye kugaya vhiri kupfeka pane roughness
3) Kupesvedzera kwezvinhu zvemuviri: deformation yepurasitiki yesimbi yakatsetseka: kusarudzwa kwekukuya dosage vhiri.
Edza kuongorora zvinhu zvinokanganisa basa rinotonhora kuoma kwenzvimbo yekucheka?
Iko pesvedzero yekucheka ma paramita pesvedzero yechishandiso geometry pesvedzero yezvinhu zvezvinhu
Chii chinonzi kugaya hasha? Chii chinonzi kugaya kudzima moto? Chii chinonzi annealing burning?
1) Kupisa: Kana tembiricha iri munzvimbo yekukuya isingapfuure tembiricha yekushandurwa kwesimbi yakaomeswa, asi yakapfuura iyo martensite shanduko yekushisa, iyo workpiece pamusoro pesimbi martensite inozoshandurwa kuita yakaderera kuomarara kwechimiro chehasha.
2) Kudzima: kana tembiricha iri munzvimbo yekukuya ichipfuura tembiricha yechikamu, yakasanganiswa nekutonhora kweiyo inotonhorera, iyo simbi yepamusoro ichaonekwa yechipiri quenching martensite chimiro, kuomarara kwakakwira kupfuura yekutanga martensite; Muchikamu chayo chezasi, nekuda kwekunonoka kutonhora, matishu ane hasha ane kuomarara kwakaderera pane yekutanga tempered martensite inoratidzika.
Annealing: Kana tembiricha iri munzvimbo yekukuya ichipfuura tembiricha yechikamu uye pasina chinotonhodza panguva yekukuya, simbi yepasi inenge iine anneal structure uye kuoma kwesimbi yepasi kunodzikira zvakanyanya.
