Transfer mechanism for automatic forging machines - is designed for moving blanks between stations in hot forging

摘要

A rack (100) meshes with a gear (101) on a vertical shaft (102) having eccentrics top and bottom (104). These impart reciprocating motion to horizontal shafts connected, one at the top (18) one at the bottom (19), by joints (106, 107, 109, 110) and running in guide bearings (22, 25, 29, 30) in sub-frames (16, 17) pivoting in a main frame (12, 13, 14, 15). An oscillating motion is imparted by a rod (62) and straight line parallel motion is maintained by a guide arm (66, 67) on each shaft constrained between guideways (70, 71, 72). The free end of each shaft has grippers (31, 49) to move the blank (60). One (31) is pivoted (115), with spring loaded fingers (36, 37, 38, 39) and the other (49) is fixed and has solid fingers (51, 53, 54).
