Introduced the researching situation of a Key Type proj ect of equal temperature die forging of TA1 5 Titanium alloy,briefly presented researching procedure like forging design,die manufacture,forging stock,and forging process, mainly focused on analysis,research ,and conclusion forging process characteristics and existing problems of forging pieces, and gave the solution aimed at the problems.The project used 8 000 t hydraulic machine and took equal temperature forging technology,produced big scale die forging piece of working allowance of main body only 4~5 mm and overall sizes reaching 1 570 mm×1 500 mm×80 mm,which was the first time trail production at home,and broke through the traditional manu-facturing way of die forging production.The results provided new way for big scale forging production.
