Taking stamping production line as the research object, a simulation method of building multi-robot stamping production line using RobotStudio was introduced. Firstly, the production line simulation platform was built according to the processing objects. In order to simplify the model of the punch press, the 3D model was directly constructed by using the internal functions of RobotStudio. The workflow of stamping production line was analyzed, I/O signal was created, dynamic component design and workstation logic design were carried out for robot and peripheral equipment. Finally programming and simulation. The simulation results show that the TCP speed parameters of industrial robots seriously affect the production line beats. The stamping simulation production line can provide theoretical basis and test platform for the actual stamping production line.
