Press has secondary movement converter arranged at frame to reciprocatingly move balanced weight contrary to slide

摘要

A primary movement converter transmits the rotary motion of a crankshaft (20) which is rotatably arranged in a frame (14), to a slide (30) which is arranged to be reciprocally movable in horizontal and vertical directions. A secondary movement converter arranged in the frame, transmits the slide movement to a balanced weight (34) and reciprocatingly moves the balanced weight contrary to the slide.
