Multiple tooling roll forming machine with turret type rotary motion

In a roll forming machine having a base, a top plate on the base, a motor drive, a gear drive transmission connected to the motor drive and a plurality of vertically aligned power rotated longitudinally spaced pairs of complimental forming rolls arranged in a longitudinal set to successively receive therebetween an elongated strip of stock in a continuous operation, and gear means interconnecting said transmission and forming rolls for rotation thereof in unison;

• the improvement comprising a turret mount assembly supporting a plurality of radially extending preset sets of form roll tooling, each set being adapted for different form of product, one of said sets having a horizontal outwardly directed operational position, said turret assembly adapted for selected limited rotation upon a longitudinal axis to rapidly place any one of said plurality of preset sets in operational position;
• said turret mount assembly including interconnected right angularly related front, rear, top and bottom plates and a pair of end plates;
• a pair of aligned outwardly directed trunnion shafts secured to said end plates respectively, upon said axis;
• and
• a pair of apertured upright end supports secured upon said top plate journaling said trunnion shafts.

• said transmission including a speed reducer having an input shaft connected to said motor drive and an output shaft mounting a first drive gear;
• an oscillating yoke pivotally mounted upon said ouptut shaft and enclosing said first drive gear;
• an oscillating drive gear journaled upon said yoke in mesh with said first drive gear and in a first position of said yoke in driving engagement with the gear means for said forming rolls, and in a second position disconnected from said gear means;
• and
• a reciprocal clamp means connected to said yoke for moving and retaining said yoke in said first position, and selectively pivoting said yoke to said second position.
