Amalungu abunjiweyo aveliswa ngenkqubo yokubumba. I-Forging yohlulwe ibe ziindidi ezimbini: i-forging eshushu kunye ne-forging ebandayo. Ukubunjwa okushushu kusenziwa ngaphezulu kweqondo lobushushu lentsimbi. Ukwandisa i

ubushushu bunokuphucula iplastiki yesinyithi, enenzuzo ekuphuculeni umgangatho ongaphakathi we-workpiece kunye nokwenza kube lula ukuqhekeka. Amaqondo obushushu aphezulu kunokunciphisa ukumelana deformation

intsimbi kunye nokunciphisa iitoni zoomatshini bokubumba obufunekayo. Nangona kunjalo, zininzi iinkqubo zokubumba ezishushu, ukuchaneka kwe-workpiece kumbi, kwaye umphezulu awugudi. Amalungu abunjiweyo anesiphumo aqhelene nawo

i-oxidation, i-decarburization kunye nomonakalo ovuthayo.

Cold forging is forging olwenziwa kwiqondo lobushushu elisezantsi kunobushushu recrystallization yentsimbi. Ngokuqhelekileyo, ukubumba okubandayo kubhekiselele ekwenziweni kwiqondo lokushisa, ngelixa ubumba kwiqondo lokushisa

ubushushu obuphezulu kunobuqhelekileyo kodwa obungagqithiyo kwiqondo lobushushu lekristali bubizwa ngokuba yi forging. Ngokwenza okufudumeleyo. Ukubunjwa okufudumeleyo kunokuchaneka okuphezulu, umphezulu ogudileyo kunye nokumelana ne-deformation ephantsi.

Amalungu abunjiweyo abunjwe ngokubanda kubushushu begumbi anemilo ephezulu kunye nokuchaneka komda, umphezulu ogudileyo, amanyathelo ambalwa okulungisa, kwaye alungele imveliso ezenzekelayo. Amaninzi abandayo akhiwe kwaye abandayo

iindawo ezinesitampu zingasetyenziswa ngokuthe ngqo njengeenxalenye okanye iimveliso ngaphandle kwesidingo somatshini. Nangona kunjalo, ngexesha lokubumba okubandayo, ngenxa yeplastiki ephantsi yesinyithi, ukuqhekeka kulula ukwenzeka ngexesha lokuguqulwa kunye

ukuchasana noguquko kukhulu, kufuna oomatshini bokwenza iitoni ezinkulu.

I-Hot forging isetyenziswa xa i-workpiece inkulu kwaye inzima, izinto eziphathekayo zinamandla aphezulu kunye neplastiki ephantsi. Xa isinyithi sineplastiki eyaneleyo kwaye isixa sokuguqulwa asisikhulu, okanye xa inani lilonke

I-ofdeformation inkulu kwaye inkqubo yokubumba esetyenzisiweyo inceda ukuguqulwa kweplastiki yesinyithi, ukubunjwa okushushu akusoloko kusetyenziswa, kodwa kusetyenziswa ukubumba okubandayo endaweni.

Ukuze kugqitywe umsebenzi omninzi wokwenza into enokwenzeka kwisifudumezi esinye, uluhlu lweqondo lobushushu phakathi kweqondo lobushushu lokuqala lokubunjwa kunye neqondo lokugqibela lokubunjwa kobushushu obushushu kufuneka libe likhulu kangangoko.

Nangona kunjalo, ukuba iqondo lobushushu lokuqala liphezulu kakhulu, liya kubangela ukuba iinkozo zentsimbi zikhule kakhulu kwaye zibangele ukufudumeza, okuya kunciphisa umgangatho weendawo ezibunjiweyo.

zezi: carbon steel 800 ~ 1250 ℃; ingxubevange yentsimbi yesakhiwo 850 ~ 1150 ℃; isantya esiphezulu sentsimbi 900 ~ 1100 ℃; ialluminiyam esetyenziswa ngokuqhelekileyo 380 ~ 500℃; ingxubevange yetitanium 850 ~ 1000℃; ubhedu700 ~900℃. Xa ubushushu bunjalo

kufuphi nendawo yokunyibilika kwesinyithi, ukunyibilika kwezinto eziphantsi kwe-intergranular kunye ne-oxidation ye-intergranular kuya kwenzeka, okukhokelela ekutshiseni. Izikhewu ezitshiswe ngaphezulu

zikholisa ukuphuka ngexesha lokurhwasha
