Abstract
A bending apparatus in one aspect of the present disclosure comprises a robot, a chuck mechanism, and a plurality of bending mechanisms. The plurality of bending mechanisms are each provided as a separate component from the robot and the chuck mechanism, and are arranged in a space reachable by a workpiece held by the chuck mechanism.
Claims16
A bending apparatus for bending a workpiece having an elongated shape, the bending apparatus comprising:
- a robot with an articulated arm;
- a chuck mechanism coupled to a distal rotary shaft at one end of the articulated arm through a gear box and a bracket, and configured to hold the workpiece;
- and
- a plurality of bending mechanisms each comprising a bending die and a clamping die to engage with the bending die, and configured to bend the workpiece by clamping the workpiece with the bending die and the clamping die,
- wherein the plurality of bending mechanisms are each provided as a separate component from the robot and the chuck mechanism, and are arranged in a space reachable by the workpiece held by the chuck mechanism,
- wherein the gear box comprises an input gear, an output gear, and a casing, the input gear being coupled to the distal rotary shaft, and the output gear being coupled to an output shaft,
- wherein a gear ratio between the input gear and the output gear is adjusted such that a rotation number of the output gear is increased more than a rotation number of the distal rotary shaft, and
- wherein one end of the bracket is coupled to the output shaft through a bearing so as to be rotatable relative to the casing.
