Ndeapi matambudziko anogona kuitika kana kuregerera kwakadzimwa uye kutonhodzwa?

Nhasi, ini ndichakutora kuti unzwisise kuti kupisa kwemhando yepamusoro matambudziko anogona kuitika panguva yekudzima uye kutonhodza maitiro ekuregerera ari kunyanya: kusakwana kuomarara mushure mekudzima, kuomarara kusaenzana munzvimbo yakadzimwa, kusakwana kwekudzima kuomesa kudzika; kunyanyisa kuomarara kwepakati mushure mekudzima; kunyanyisa kudzima deformation; kudzima kutsemuka; Kupenya kwepamusoro hakuna kukwana mushure mekudzima mafuta.

Tevere, ini ndichakuudza zvakadzama nezve zvemhando yepamusoro matambudziko uye mhinduro dzekuregerera panguva yekudzima uye kutonhora:

Kusakwanira kuomarara uye kusakwana kwekuomesa kudzika: Iyo yakadzika kudzima kutonhora mwero ndicho chikonzero chekusakwana kwekudzimisa kuomarara, kusaenzana kuomarara uye isina kukwana kuomesa kudzika kwekuregerera. Nekudaro, zvinoenderana neicho chaicho zvinhu, chimiro, saizi uye kupisa kurapwa zvinodiwa zveiyo chaiyo yakadzimwa kukangamwirwa, inogona kuganhurwa kuita yakanyanya tembiricha Kune akasiyana mamiriro akaita seisina kukwana kutonhora mwero mumatanho, kukwana kukwana kutonhora mwero mune yepakati uye yakadzika tembiricha matanho, uye kukwana kwakaringana kutonhora mumatanho epasi ekushisa. Semuyenzaniso. Kune madiki uye epakati kukanganwira, kukwana kwakaringana kudzima kuomarara kunowanzo kukonzerwa neisina kukwana kutonhora mwero pakati nepakati tembiricha nhanho. Kana forgings ine hombe modulus inoda yakadzama yakaoma simbi, zvinonyanya kukosha kuti uwedzere yakaderera tembiricha kutonhora chiyero. Zvekudzima mafuta, kazhinji kutaura, iyo oiri ine pfupi mhute firimu nhanho, inokurumidza kutonhora mwero pane yepakati tembiricha, uye inokurumidza kutonhora mwero pane yakaderera tembiricha, iyo inogona kazhinji kuwana yakakwira uye yunifomu kudzimisa kuomarara uye yakakwana kudzima kudzika.

Iyo nzira iyo workpiece yakaiswa zvakare ine yakakosha mhedzisiro pane kudzima kutonhora mhedzisiro. Izvo zvinodikanwa kuita kuti oiri inodzima kuyerera isavharwe, uye kugadzirira uye kushandisa yakanaka yekusanganisa mudziyo kuti uwane mhedzisiro. Kuwedzera iyo yakadzika-tembiricha kutonhora chiyero cheiyo quenching svikiro inoshandiswa kazhinji inogona kuwedzera kudzika kweyakaomeswa dura. Muchiitiko cheiyo imwechete kabhoni yekupararira kwekupararira mune yakakwenenzverwa dura, iko kushandiswa kweanodzima mafuta ane yakanyanya yakaderera-tembiricha kutonhora chiyero kunowanzoita kuwana yakadzika kudzima yakaomeswa dura. Naizvozvo, kushandiswa kwemafuta ekudzimisa ane inotonhora kutonhora mwero kunogona kupfupisa iyo carburizing nguva yeiyo workpiece zvinoenderana. Unogona kuwana iyo inodiwa kudzika kwekudzima uye kuomesa dura. Iyo yakakura kudzama kweiyo carburized yakaoma kuomesa dura inodiwa, zvinonyanya kuoneka mhedzisiro yeiyi nzira mukupfupisa iyo carburizing nguva.

Iko kuomarara kwepakati mushure mekudzima kwakanyanya zvakanyanya: mhando yechinetso ichi inogona kunge ichienderana neyekumhanyisa kutonhora chiyero cheiyo yakasarudzwa svikiro kana yakanyanya kukwirira yakadzika tembiricha kutonhora chiyero chepakati. Imwe yemhinduro ndeyokuchinja oiri inodzima kuti iite zvinodiwa. Iyo nzira yechipiri ndeyekubata iyo inogumisa yepakati inogadzira uye wedzera zvakafanira zvinowedzerwa kuti udzikise iyo inotonhorera mwero weanodzima mafuta mune yepakati uye yakadzika tembiricha. Nzira yechitatu ndeyekuchinjira kune simbi ine kuomarara kwakaderera.

Kupedza chinetso che deformation: Kuchenesa deformation kwakonzera mafekitori mazhinji kufunga. Zvinoenderana netsika, mhinduro yedambudziko rekushomeka kazhinji inosanganisira madhipatimendi mazhinji, uye mhinduro yacho inowanzove chiyero chakazara. Chikonzero chikuru chekushomeka kwakakonzerwa nekukanganisa kutonhodza uye kutonhora zvisina kuenzana, uye pachikonzero ichi, nzira yekugadzirisa nzira yekuwedzera mwero wekutonhora uye kuyedza kutonhodza yunifomu inokurudzirwa. Matanho ekuwedzera iyo yekudzimisa kutonhora mwero inofanirwa kuwedzerwa chete kana matanho munzira imwechete yekuita akasarudzwa zvine musoro. Iyo inogona kugadzirisa kudzimisa deformation dambudziko revanonyanya kukanganwira. Semuenzaniso, iko kushomeka kwemukati spline gomba rekugadzira kunowanzo kukonzerwa neisina kukwana yakanyanya tembiricha kutonhora mwero weakasarudzwa kudzima mafuta, kana yakanyanyisa kureba mhute firimu nhanho yemafuta. Kuwedzera iyo yepamusoro-tembiricha kutonhora chiyero chemafuta uye kuwedzera iyo inotonhorera mwero wemafuta mune yese kutonhora maitiro kunogona kazhinji kugadzirisa dambudziko rekushomeka kwemukati spline gomba. Zvekukanganwirwa, kunyanya zvakanyatso kukanganwirwa, sarudzo yakanaka uye kushandiswa kwe isothermal grading quenching oiri ndiyo nzira yakakosha yekudzora deformation.

Kuchenesa kutsemuka kwekuregerera: Iri dambudziko rinonyanya kuitika mukumisikidza kupisa kupisa. Sarudza yakanaka mvura-based quenching medium, senge iyo PAG inodzima svikiro inowanzo shandiswa kumba nekune dzimwe nyika kutsiva iyo yekutanga pombi yemvura, dambudziko rinogadziriswa. PAG yepakati inoshandiswa induction kupisa uye kudzima. Yakakwirira uye yunifomu inodzima kuomarara uye yakadzika uye yakagadzikana yakaoma kuisirwa inogona kuwanikwa, uye njodzi yekudzima kutsemuka idiki zvakanyanya.

Dambudziko rekujeka: Kune dzimwe nguva panodiwa chinhu ichi, oiri yakajeka yekudzima kana mafuta anomhanya anopenya anofanirwa kushandiswa. Kazhinji, iyo inotonhorera mwero unopenya wekudzimisa mafuta haukwane zvakakwana kana kupenya kwemwenje unopfuta oiri kwakanaka, uye kupenya kwemafuta ekudzimisa ane yakanyanya kutonhora mwero hakuna kukwana zvakakwana. Uye zvakare, kupenya kwemafuta anopisa kunowanzo kuve kwakashata. Unogona kushandura mafuta kana kuwedzera zvinowedzera kuti uvandudze kupenya.
