Abstract
A feeder mechanism for feeding a sheet of metal to be blanked in a zigzag fashion in cooperation with a sheet of metal feeder mechanism of a press. A reversible D.C. motor is employed for reciprocating the sheet of metal in a direction at right angles to the sheet of metal feed direction of the press. The forward and reverse rotation and its cycle of the D.C. motor are controlled by a controller in synchronism with the feeding speed of the sheet of metal. The rotational motion of the D.C. motor is translated into a linear reciprocating motion of a die set by a rack and pinion mechanism. The rack is connected to the die set and is reciprocated in a direction at right angles to the sheet of metal feed direction of the press.
Claims2
A feeder mechanism for feeding a sheet of metal to be blanked in a zigzag fashion in cooperation with a sheet of metal feed means of a press, comprising:
- a die set of the press;
- a rack connected to said press, said rack extending in a direction at right angles to the feed direction of the sheet of metal of the press;
- a D.C. motor;
- means for translating a rotational motion of said D.C. motor into a linear motion of said rack;
- and
- controller means for controlling rotational direction of said D.C. motor forwardly and reversely at a preset cycle thereby reciprocating said rack and said die set in a direction at right angles to the feed direction of the sheet of metal.
