ABSTRACT:
An adjustable kickout drive for forming machines is disclosed which can be adjusted while the machine is running. The drive includes a drive cam and a kickout lever, both of which oscillate about pivots. The drive cam is driven through a predetermined angle of oscillation from the main machine drive. The kickout lever is provided with a cam surface adjacent to the drive cam and a roller system is positioned between the cams so that the kickout lever oscillates through an angle in response to the oscillating rotation of the drive cam. The rollers are mounted on a lever, which is in turn pivoted on an adjusting screw which threads through a nut journaled on the machine frame. Rotation of the nut moves the screw, and in turn changes the position of the rollers with respect to the cam surfaces. The drive cam and the kickout lever are provided with straight cam surfaces which are parallel in the operative position of the kickout system so that adjustment of the screw does not change the operative position but only changes the stroke and retracted or rearward position of the kickout drive.
