Abstract
A direct drive working tool drive system is provided for a drawing machine. Electromagnetic means move the working tool downward toward the working surface of the drawing machine. Resilient means move the working tool upward from the working surface. First and second stroke limit means limit the upward and downward movement of the working tool. The electromagnetic means, resilient means, and first and second stroke limit means are disposed coaxially with the longitudinal axis of the working tool. Suitably, the electromagnetic means comprise a magnetic core having the working tool fixed within it, with the magnetic core being disposed within a solenoid coil. The magnetic core and solenoid coil are disposed coaxially with the longitudinal axis of the working tool.
