Forging Heating Method

Kazhinji, kupisa kwekugadzira uko kuwanda kwekupisa kurasikirwa kuri 0.5% kana kushoma kushoma oxidative kudziyisa, uye kupisa uko huwandu hwekupisa kurasikirwa kuri 0.1% kana kushoma kunonzi kusiri-oxidizing kupisa. Kudziisa kushoma oxidation-isina kupisa kunogona kuderedza simbi oxidation uye decarburization, uye inogona zvakare kuvandudza zvakanyanya kunaka kwepamusoro uye dimensional kurongeka kwefogi uye kuderedza kupfeka mold. Ishoma oxidation-yemahara yekudziya tekinoroji ndiyo yakakosha kutsigira tekinoroji yekunyatso kuforoma. Parizvino, tekinoroji iyi haisati yaita basa rakawanda rekutsvagisa muChina.

 

Pane nzira dzakawanda dzekuwana kushoma oxidation-isina kudziyisa. Nzira dzinowanzo shandiswa uye dzinokurumidza kukurumidza kupisa kupisa, kudzivirira kwepakati kupisa uye kushoma oxidizing murazvo kupisa.machining chikamu

 

-, kupisa nekukurumidza

Kukurumidza kupisa kunosanganisira kupisa nekukurumidza uye kumhanyisa kupisa, induction yemagetsi kupisa, uye kubata magetsi kupisa muvira remoto. Iyo theoretical hwaro hwekukurumidza kupisa ndeyekuti kana simbi isina kuvharwa ichidziya pahunyanzvi hwekupisa mwero, iyo yepamusoro yekushushikana kwekushisa, kusara kwasara kushushikana uye kushushikana kwematishu kunogadzirwa mukati mebillet hakuna kukwana kukonzera kutsemuka kwebillet. Iyi nzira inogona kushandiswa kune madiki-saizi kabhoni simbi ingots uye ma blanks eyakajairwa forging yeakareruka maumbirwo. Sezvo nzira iri pamusoro ine yakakwirira yekupisa, nguva yekupisa ipfupi, uye oxide layer inoumbwa pamusoro pebillet yakaonda, kuitira kuti chinangwa che oxidation chiduku.

Kana induction kupisa, kuwanda kwekupisa kwesimbi inenge 0.5%. Kuti uwane chinodikanwa chekusapisa oxidation, gasi rinodzivirira rinogona kuunzwa muchoto chekupisa. Iyo inodzivirira gasi igasi inert senge nitrogen, argon, helium kana zvimwe, uye gasi rinoderedza senge musanganiswa weCO neH2, iyo yakanyatsogadzirirwa neinodzivirira gasi rinogadzira mudziyo.cnc

Sezvo kupisa nekukurumidza kunopfupisa zvakanyanya nguva yekudziya, dhigirii re decarburization rinogona kudzikiswa zvakanyanya nekudzikisa oxidation, iyo yakasiyana neiyo shoma oxidizing kupisa kwemoto, inova imwe yemabhenefiti makuru ekukurumidza kupisa.chikamu chepurasitiki

 

2, mvura yepakati kudzivirira kudziyisa

 

Yakajairika mvura yekudzivirira midhiya magirazi akanyungudutswa, munyu wakanyungudutswa, nezvimwe zvakadaro. Iyo yekugezera munyu yekudziya yevira inotsanangurwa muchikamu chekutanga cheChitsauko 2 imhando yemvura yepakati kudzivirira kudziyisa.

 

Mufananidzo 2-24 inoratidza pusher mhando semi-inoenderera girazi yekugezera choto. Muchikamu chekupisa chechoto, girazi rakanyungudutswa rakanyungudutswa rinonyungudutswa pasi pechoto, uye billet inopisa mushure mekuramba ichisundirwa kuburikidza negirazi remvura. Nekuda kwekudzivirirwa kwegirazi remvura, iyo billet haina oxidized panguva yekupisa, uye mushure mekunge billet ichisundirwa kunze kwegirazi remvura, iyo nzvimbo iri pamusoro. Yakasungirirwa kune yakaonda yegirazi firimu, haingodziviriri yechipiri oxidation yebillet, asiwo inoizora panguva yekugadzira. Iyi nzira inokurumidza uye yakafanana mukudziya, ine yakanaka oxidation uye decarburization mhedzisiro, uye iri nyore kushanda, uye inovimbisa kushoma oxidation-isina kupisa nzira.
3, yakasimba yepakati kudzivirira kudziyisa (coating kudzivirira kudziyisa)

 

Mushonga unokosha unoshandiswa pamusoro pechinhu chisina chinhu. Kana ichipisa, iyo yekuputira inonyunguduka kuita dense uye airtight coating film. Yakasungirirwa zvakasimba pamusoro pechisina kuvharwa kuti iparadzanise isina chinhu kubva kune oxidizing choto gasi kudzivirira oxidation. Mushure mokunge billet yabudiswa, kuvhara kunogona kudzivirira yechipiri oxidation uye ine kupisa kwekudzivirira, iyo inogona kudzivirira kudonha kwekushisa kwepamusoro kwebillet uye inogona kuita semafuta panguva yekugadzira.

 

Iyo inodzivirira yakavharwa yakakamurwa kuita girazi rejasi, girazi resimbi yeramic, girazi resimbi yesimbi, simbi yesimbi, inoumbwa nekubatanidza, uye zvakafanana zvinoenderana nekuumbwa kwayo. Inonyanya kushandiswa ndiyo girazi rekuvhara.

 

Girazi coatings ndeye kumiswa kweimwe chimiro chegirazi poda, pamwe nediki diki re stabilizer, binder uye mvura. Usati washandiswa, pamusoro pechinhu chisina chinhu chinofanira kucheneswa nejecha rejecha, nezvimwewo, kuitira kuti nzvimbo yekuputira uye isina chinhu inogona kusungwa zvakasimba. Mabatiro anoshandiswa ne dip coating, brush coating, spray gun spraying uye electrostatic spraying. Iyo yekupfeka inodiwa kuti ive yunifomu. Ukobvu hwakakodzera. Kazhinji, iri 0.15 kusvika 0.25 mm. Kana iyo yakanyanyisa kukora, iri nyore kuibvisa, uye yakanyanya kutetepa kudzivirira. Mushure mekuputira, inoomeswa nemhepo mumhepo uye yozoiswa muhovhoni yekuomesa yakaderera yekuomesa. Izvo zvakare zvinokwanisika kupisa billet kusvika 120 ° C isati yapfekedzwa, kuitira kuti poda yakanyorova iomeswe pakarepo mushure mekushandisa, uye inonamatira zvakanaka pamusoro peiyo isina chinhu. Iyo pre-forging heat inogona kuitwa mushure mekuputira kwaoma.

 

Kuti upe kudzivirirwa kwakanaka uye kunyura kwegirazi rekudzivirira kwegirazi, kupfeka kunofanirwa kunyungudutswa zvakanaka, viscous uye kugadzikana kwemakemikari. Kana iyo yakasiyana-siyana yekugovera reshiyo yegirazi yakasiyana, iyo iri pamusoro pemuviri nemakemikari zvimiro zvakasiyana. Naizvozvo, kushandiswa kunoenderana nerudzi rwesimbi zvinhu uye chiyero chekushisa kwekugadzira. Sarudza zvakakodzera girazi zvigadzirwa.

 

Iyo girazi yekudzivirira yekudzivirira nzira yekudziya yakashandiswa zvakanyanya mukugadzirwa kwetitanium alloy, simbi isina tsvina uye superalloy aviation forgings muChina.
