Abstract
A transmission device for a tube bending machine include a first power means and a second power means mounted on the sliding seat to drive the sliding seat as well as a workpiece securely connected to the sliding seat to move. The second means has a second motor alternately connected to the clutch so that the transmission power is selectively transmitted to drive the sliding seat when required. Therefore, transmission of workpiece is smooth and the processing work to the workpiece is accomplished.
