Abstract:
A bending device having a chuck mechanism for holding a longitudinal work piece, a first joint type robot, a second joint type robot, the first and second joint type robots each having at least three joints rotating around axes, a bending mechanism attached to a remote end of each of the first and second joint type robots for holding said work piece, each bending mechanism comprising a bending die, a clamping die and a pressure die and bending of the workpiece is performed via the bending, the clamping and the pressure dies;the bending device further comprising:working data preparing means for preparing working data from design data of said work piece via an inputted orthogonal coordinate system, the working data comprising a feeding pitch between bending points along the work piece, a bending angle of a bend and a direction of the bending angle;movement control means for controlling movement of said joints of said first and second joint type robots based on said working data supplied by the working data preparing means; andcorrecting means, communicating with said movement control means, for correcting said working data in response to at least one input.
