Kupisa kwakadzikakabhoni simbi pombiisimbi yekabhoni yesimbi, yakadzika tembiricha kabhoni simbi pombi inoshandiswa mune yakaderera tembiricha mamiriro, ayo anogona kutsungirira imwe yakaderera tembiricha maitiro, kuita kwemakanika kuri nani, uye mutengo wakaderera, wakafara sosi, saka unoshandiswa zvakanyanya.Utera hwayo hukuru ndeyekuomeswa kwakaderera, saizi yechikamu cheJapan yakakwira zvinodiwa zveiyo workpiece haifanirwe kushandiswa.
Yakadzika tembiricha kabhoni simbi pombi inodzima tembiricha muA3 + (30 ~ 50) ℃, mukuita, inowanzoiswa kumuganhu wepamusoro.Yakakwira yekudzima tembiricha yekupisa pombi inogona kuita yakaderera kumhanya, pamusoro oxidation kuderedza, uye inogona kuvandudza kushanda zvakanaka.Iyo workpiece iri yunifomu austenite, inoda yakakwana yekubata nguva.Kana iyo chaiyo yakaiswa choto simba, ingada kuve yakakodzera kuwedzera nguva yekubata.Zvikasadaro, panogona kuve nekusakwana kuomarara nekuda kwekudziya kusina kuenzana kunokonzerwa nechiitiko.Nekudaro, iyo nguva yekubata yakarebesa, ichaonekwawo coarse zviyo, oxidation uye decarbonization zvakakomba zvakaipa zvinokanganisa kudzima mhando.Isu tinotenda kuti kana choto chakaiswa chakakura kupfuura magwaro ekuita, kupisa kwekubata nguva kuwedzeredzwa 1/5.Yakaderera tembiricha kabhoni simbi pombi nekuda kwekuderera kuomarara, inofanirwa kutora yakakura yekutonhodza mwero we10% munyu munyu.Workpiece mumvura, inofanira kuoma, asi isina kutonhora, kana 45 # chaiyo simbi yakanyungudutswa mune brine, zvinogoneka kuputika kweiyo workpiece, izvi zvinodaro nekuti kana workpiece yatonhodzwa kusvika 180 ℃, iyo austenite inokurumidza kushandurwa kuita muviri webhiza. tishu zvinokonzerwa nekunyanya kushushikana nekuda.Naizvozvo, kana simbi yekudzima nekudziya yakakurumidza kutonhora kusvika kune ino tembiricha, nzira yacho inofanira kutorwa kuti inonoke kutonhora.Sezvo tembiricha yemvura yakaoma kunzwisisa, ruzivo rwekuzvidavirira mukushanda, kana mvura yamira kudithering zvigadzirwa, unogona kunwisa mvura yakatonhodzwa (semuoiri inotonhorera inogona kuve nani).Mukuwedzera, iyo workpiece mumvura, chiito chakakodzera chinofanira kuramba chichienderana nejometri ye workpiece, sekugara uchidzidzira.Yakamira yekutonhodza yepakati uye yakamira workpiece, zvichikonzera kuoma kusina kuenzana, kushushikana kusaenzana kunosiya deformation yakakura yeworkpiece, uye kunyange kutsemuka.
Yakaderera tembiricha kabhoni simbi nyere nhengo kudzima kuomarara pashure quenching anofanira kusvika HRC56 ~ 59, mukana mukuru muchinjikwa-chikamu yakaderera, asi kwete asingasviki HRC48, zvikasadaro, zvinoratidza workpiece haina kuomeswa zvachose, sangano anogona kuva ferrite kana sorbite. matishu, masangano akadaro nekudzikamisa, achiri akachengetwa mumatrix, ayo asina kudzimwa zvinangwa.Low kabhoni simbi pombi tempering pashure quenching, tembiricha kudziyisa kazhinji 560 ~ 600 ℃, kuomarara iri HRC22 ~ 34. Nokuti chinangwa kuwana kudzimwa michina zvinhu, saka zvakati wandei siyana kuoma.Asi kudhirowa kuomarara zvinodiwa, zvinodikanwa kugadzirisa tembiricha yekudziya zvinoenderana nemadhirowa kuti uone kuomarara.Sezvo mamwe mashafu esimbi anotonhora achida simba rakakwirira, kuoma kwakakwirira;nepo mamwe magiya keyway shaft zvikamu, nekuti kunyangwe mushure mekugaya kwadzimwa, isa kugadzirisa, kuomarara zvinodiwa kune yakaderera.About Tempering nguva, zvichienderana kuoma uye kukura workpiece, tinotenda, zvinoenderana kuoma pashure tempering tempering tembiricha uye tempering nguva shoma, asi inofanira kudzorerwa kuburikidza mukuru nguva dzose kushanda Tempering Time awa imwe kana kupfuura.
