    • A transfer feeder for a forging press includes a pair of parallel feed bars each having article-grasping claws, the feed bars being able to make a three-dimensional movement (i.e., an advance-return movement of the feed bars in a longitudinal direction, a clamping-unclamping movement of the feed bars in a widthwise direction, and a lift-down movement of the feed bars) so as to feed forging workpieces from one step of a pressing process to another. The transfer feeder further includes lift-down devices each for making a lift-down movement relative to a corresponding transfer frame through a lift-down linear-movement mechanism, advance-return devices each for making an advance-return movement relative to a lift-down frame of the associated lift-down device through an advance-return linear movement mechanism, and clamping-unclamping devices each for making a clamping-unclamping movement relative to an advance-return frame of the advance-return device through a clamping-unclamping linear-movement mechanism. The advance-return devices respectively include advance-return drive portions which are provided adjacent respectively to opposite ends of the feed bars so as to feed the feed bars in the same direction in synchronism with each other. The lift-down devices, as well as the advance-return devices, and the clamping-unclamping devices, are mounted respectively within the transfer frames which are provided adjacent respectively to the opposite ends of the feed bars, and are disposed at a level higher than the feed bars.
    • 用于锻压机的转送给料机包括一对平行进给杆,每个进给杆均具有制品夹紧爪,进给杆能够进行三维运动(即进给杆在纵向上的前进运动, 进给杆沿宽度方向的夹紧松开运动,以及进给杆的升降运动),从而将工件从压制过程的一个步骤进给到另一个步骤。 传送进料器还包括提升装置,每个用于通过升降线性运动机构相对于相应的传送框架进行升降运动,每个用于相对于升降机构进行前进返回运动的提前返回装置, 相关联的升降装置的下降框架通过提前返回线性移动机构,以及夹紧松开装置,每个夹紧装置通过夹紧松开线性相对于提前返回装置的前进返回框架进行夹紧松开运动 运动机制。 前进返回装置分别包括提前返回驱动部分,其分别设置在进给杆的相对端附近,以便彼此同步地沿相同方向供给进给杆。 拆卸装置以及推进返回装置和夹紧松开装置分别安装在传送框架内,传送框架分别邻近进给杆的相对端设置,并且设置在更高的高度 比进料棒。
