    • 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.
    • 一种馈送机构,用于与印刷机的金属馈送机构一起配合以锯齿形的方式供给要冲裁的金属片。 使用可逆的直流电动机使金属片沿与压机的金属馈送方向成直角的方向往复运动。 直流电机的正向和反向旋转及其循环由控制器与金属板的进给速度同步控制。 直流电动机的旋转运动被转换成由齿条和小齿轮机构设置的模具的线性往复运动。 机架连接到模具组件并且沿与压力机的金属进给方向成直角的方向往复运动。
