APPARATUS FOR CHANGING A DIE SET USED IN FORGING PROCESS

摘要

A changing apparatus of a mold for forging is provided to perform a replacement operation of the mold in an easy and simple manner and prevent damage of the mold or safety accident of an operator by mechanizing and automating a series of processes of demounting the mold from a bolster to replace a mold and mounting other mold on the bolster. A changing apparatus of a mold for forging comprises: a post(P) which is installed in front of a forging press, and on which the supporting frame is mounted; a tilting and lifting unit for vertically sliding the lifting frame formed on the center of the supporting frame by rotating a lifting lead screw and rotating the tilting frame axially connected to the lifting frame by the sliding operation; and replacement equipment for clamping a mold in the forging press through a finger installed on a front end of the arm and mounting the mold on a top part of the tilting frame to transfer the mold in all directions and rotate the mold. The tilting and lifting unit includes a supporting frame(10), a lifting frame(20), a lifting lead screw, a lifting servo motor(M), a tilting frame(30), a roller, and lead-in holes. The replacement equipment comprises: a lower frame transfer unit including a first connecting frame, a lower frame(40), a first lead screw, and a first servo motor(M1); an upper frame transfer unit including a second connecting frame, an upper frame(50), a second lead screw, and a second servo motor(M2); an arm transfer unit including a rotary frame(60), an arm(70), a third lead screw, a third servo motor(M3), and a clamping unit; and an arm rotating unit including a connecting housing(80), a rotary shaft, an inner wheel gear, a fourth servo motor(M4), and a power transmission unit.
