Abstract
A bender includes a rotatable bending shoe having a plurality of channels therein configured to receive a workpiece and a follower assembly. The follower assembly includes a mount, a follower bar attached to the mount, the follower bar having a plurality of channels therein configured to receive the workpiece, a roller attached to the mount and engaged against the follower bar, the roller having an eccentric shaft extending therefrom, and a motor for rotating the shaft and roller, wherein rotation of the shaft and roller causes the follower bar to translate toward or away from the bending shoe. A drive member can be provided to move the mount toward or away from the bending shoe.
Claims18
A bender comprising:
- a rotatable bending shoe having a plurality of channels therein configured to receive a workpiece and to bend the workpiece in a bending operation;
- and
- a follower assembly including
- a mount, the mount being stationary during the bending operation,
- a follower bar movably attached to the mount, the follower bar having a plurality of channels therein configured to receive the workpiece,
- a roller attached to the mount by an eccentric shaft extending therefrom, the roller being engaged against the follower bar, and
- a motor for rotating the shaft and roller relative to the mount and relative to the follower bar, wherein rotation of the shaft and roller causes movement of the follower bar relative to the bending shoe and relative to the mount.
A bender comprising:
- a rotatable bending shoe having a plurality of channels therein configured to receive a workpiece;
- and
- a follower assembly including
- a mount,
- a follower bar attached to the mount, the follower bar having a plurality of channels therein configured to receive the workpiece,
- a roller attached to the mount by an eccentric shaft extending therefrom, the roller being engaged against the follower bar,
- a motor for rotating the shaft and roller, and
- a drive member connected to the mount and configured to move the mount toward or away from the bending shoe such that a space between the follower bar and the bending shoe is increased or decreased.
A bender comprising:
- a first rotatable bending shoe having a plurality of channels therein configured to receive a workpiece;
- a second bending shoe;
- a follower assembly including
- a first mount,
- a first follower bar attached to the first mount, the first follower bar having a plurality of channels therein configured to receive the workpiece, the first follower bar being movable relative to the first bending shoe,
- a first roller attached to the first mount by a first eccentric shaft extending therefrom, the first roller being engaged against the first follower bar, and
- a motor for rotating the first shaft and first roller,
- a second mount,
- a second follower bar attached to the second mount, the second follower bar being movable relative to the second bending shoe, the second follower bar having a plurality of channels therein configured to receive the workpiece,
- a second roller attached to the second mount by a second eccentric shaft extending therefrom, then second roller being engaged against the second follower bar.
A bender comprising:
- a rotatable bending shoe having a plurality of channels therein configured to receive a workpiece;
- and
- a follower assembly including
- a mount,
- a follower bar attached to the mount, the follower bar having a plurality of channels therein configured to receive the workpiece,
- a roller attached to the mount by an eccentric shaft extending therefrom, the roller being engaged against the follower bar, and
- a motor for rotating the shaft and roller;
- and
- a flexible member attached to the bending shoe and to the follower bar, wherein movement of the bending shoe causes movement of the follower bar via movement of the flexible member.
A bender comprising:
- a rotatable bending shoe having a plurality of channels therein configured to receive a workpiece;
- and
- a follower assembly including
- a mount
- a follower bar attached to the mount, the follower bar having a plurality of channels therein configured to receive the workpiece,
- a roller attached to the mount by an eccentric shaft extending therefrom, the roller being engaged against the follower bar,
- a motor for rotating the shaft and roller, and
- the mount including a plurality of wheels engaged with the follower bar.
