If it is necessary to bend the profile in both positive and negative directions, two feeding processes are required: first press the forward arc on the profile workpiece, and then take out the profile workpiece to change the direction and position to press the reverse arc. This processing method is cumbersome, time-consuming and laborious, and requires repeated adjustments to the placement angle of the profile to make the bent profile meet the design requirements. It cannot guarantee the accuracy of the transition position of the positive and negative arcs, thus affecting the processing quality of the profile. and precision.
