|
|
The warm extrusion technology of air cylinder bolt-protected screws used for the national locomotive DFTC was studied.The warm extrusion technology parameters,such as bullets,die temperature,the cooling and lubrication of die were determined,the structure of punch and die was designed,and the die strength was analyzed by ANSYS software.The results show that the warm extrusion die structure of the air cylinder bolt-protected screw is reasonable, and can meet the demands of practical production.Actual extrusion production also shows that 3.85 kg blank weight produced by the originally free forging technology is decreased to 1.3 kg for now.The rate of material utilization raises to 83.6% from original 22.7%,and 4 t steel materials can be saved annually.The results will provide beneficial basis and successful experience for the production of similar extrusion parts.
