摘　　要：在冷锻过程中,模具受到极高的载荷和磨料磨损,表面粗糙度和残余应力受到影响很大。以经过热处理的高速钢制成的模具作为研究对象,试样经过镦粗过程,得到了不同锻造条件下锻件表面粗糙度、残余应力和试样变形随锻造循环次数的变化,并在"有润滑"和"无润滑"条件下,得出了采用两种不同的锻造载荷进行了冷锻镦粗工艺对冷锻模具的影响。In the cold forging process,the die is subjected to extremely high load and abrasive wear,and the surface roughness and residual stress are greatly affected. The die made of heat-treated high-speed steel was used as the research object,and the variation of surface roughness,residual stress and deformation with the number of cold forging cycles under different forging conditions was obtained. Under the condition of " lubrication" and " no lubrication",the influence of cold forging and upsetting process on cold forging die with two different forging loads is obtained.
