Forging txheej txheem thiab kev ua tau zoo ntawm aluminium alloy

(1) Nqaim forging deformation kub ntau yam

Lub forging deformation kub ntawm feem ntau aluminium alloys yog 350? Nyob rau hauv qhov ntau ntawm 450 degree, qhov deformation kub ntau yog nyob ib ncig ntawm 100 degree, thiab deformation kub ntau yam ntawm ob peb alloys tsuas yog 50-70 degree . Lub sijhawm ua haujlwm forging tso cai yog luv. Qhov no undoubtedly coj teeb meem loj rau kev ua haujlwm forging. Txhawm rau kom tau txais lub sijhawm forging ntev, nws yog qhov yuav tsum tau ua kom sov lub qhov khoob mus rau qhov siab tshaj qhov ntsuas kub, ua kom lub forging hluav taws thiab preheat cov cuab yeej thiab tuag mus rau qhov kub siab dua.

(2) Kev sib hloov ceev ceev tus nqi rhiab heev

Aluminium alloy yog rhiab heev rau kev hloov pauv ceev, yog li nws yog qhov tsim nyog los xaiv cov cuab yeej forging nrog kev ua haujlwm qis thiab ruaj khov ceev rau forging. Rau ingots, txhawm rau tiv thaiv forging tawg, nws yog feem ntau yuav tsum tau qhib lub ingots nyob rau hauv lub xeev ntawm compressive kev nyuaj siab thiab nyob rau hauv tsawg ceev, siv extrusion, forging los yog dov. Aluminium alloy tuag forging feem ntau yuav tsum tau nqa tawm ntawm hydraulic xovxwm lossis mechanical xovxwm, thiab nws tsis yog nqa tawm ntawm forging rauj hom forging cov cuab yeej kom deb li deb tau, yog li kev xaiv cov cuab yeej forging yog me me.

(3) Cov kev cai nruj rau cua sov thiab forging kub

Raws li qhov deformation kub ntau ntawm aluminium alloy forging yog nqaim, txhawm rau kom ntev lub sijhawm ua haujlwm forging, nws yuav tsum tau ua kom sov rau sab sauv ntawm qhov kub ntawm deformation ntau npaum li qhov ua tau, uas yuav tsum tau ua kom muaj kev kub ceev thiab ntsuas kub tswj. qhov kub thiab txias; Txwv tsis pub, overheating yuav yooj yim tshwm sim.

Feem ntau ntawm aluminium alloy semi-tiav cov khoom uas tau sau nqi muaj siab plasticity thiab tsis yooj yim rau tawg raws li ib txwm muaj; Txawm li cas los xij, kev deformation hnyav yuav tsum raug zam nyob rau hauv tus txheej txheem ntawm forging kom tsis txhob muaj kev cuam tshuam ntau dhau ntawm cov qauv thiab kev ua haujlwm ntawm forgings. Yog hais tias kev kub ceev (xws li siv lub forging rauj) thiab loj deformation tau txais kev pom zoo rau forging yam tsis muaj kev xyuam xim rau kev ua haujlwm, lub zog hluav taws xob hloov pauv los ntawm ntau lub zog deformation yuav ua rau qhov kub ntawm forgings siab tshaj qhov txwv ntawm forging kub thiab ua rau kub hnyiab, ua rau cov qauv tsis tsim nyog thiab kev ua haujlwm ntawm forgings.
