摘　　要：为了增加煤矿用地质钻杆与钻头联接处的强度,通常会采用钻杆端部挤压锻造工艺对钻杆管端进行加厚处理,而煤矿用地质钻杆端部挤压锻造模具的结构尺寸是影响加厚成形工艺的关键因素。采用DEFORM软件仿真分析不同结构尺寸下的模具对钻杆管端挤压锻造过程中的应力应变分布规律和载荷分布规律的影响,以此为模具结构尺寸的优化提供依据。In order to increase the strength of the joint between geological drill pipe and drill bit for coal mine,the end of drill pipe is usually thickened by extrusion forging process. The structural size of extrusion forging die for the end of geological drill pipe for coal mine is the key factor affecting the thickening forming process. DEFORM software was used to simulate and analyze the influence of dies with different structural sizes on the stress-strain distribution and load distribution during extrusion forging of drill pipe ends,which provides the basis for optimization of die structural sizes.
