Abstract：

|
A forging system was constructed by the linkage control of robot and servo-press,and increment bending of shaft-shape part was studied with simple plane dies in this system.Based on neglecting the metal flow in wide direction,a calculating relationship equation of bending angle to forging times and compression ratio was prompted.Then the bending forming experiment was conducted in the system,and the bending parts were obtained.The results show that the calculating equation agrees with experimental data well when the compression ratio is higher and the number of compression times is larger.Moreover,the single compression length is smaller,the curvature radius is smaller.
