ABSTRACT:
To apply exactly a variety of operating patterns to an automatic transfer apparatus for use in a forging press, an arrangement is proposed comprising: intermediate frames each mounted on an external frame so as to move freely up and down; a clamp frame mounted on the intermediate frame so as to move freely in a lateral direction; a pair of beams mounted on the clamp frame so as to open and close freely; servo motors for performing upward and downward motion, lateral motion and opening-and-closing motion; and drive control equipment. The operation patters are inputted to a microcomputer for picture processing and displayed. Accordingly, the driving operations are exactly controlled by pulse signals and feedback pulses of the servo motors. The arrangement is applicable to various types of motions. Feed motion being of the longest stroke is linear and therefore positioning becomes accurate. The construction is advantageous in accomplishing a small-sized and light-weight automatic transfer apparatus.
