Abstract—Despite the flexibility in the stamping process with complex ram movement, commercial servo presses are still expensive for the affordable of medium or small enterprises. Moreover, since the movement of the ram can be precisely controlled, these systems also require high maintenance and even highly skilled workers to operate. This study proposes a design for multi-stroke forging machines, which combines a gear transmission and a 6-link mechanism to control the stroke for the ram. Experiments with several design parameter sets prove the possibility of modifying the complex movement of the rams only by changing the gear ratio and angular difference between diving shafts. Results obtained from the calculation also indicate the applicability of the proposed system in multi-stage forging and support the designing process to get complex strokes of the ram.

Keywords—forging, complex-stroke press, kinematic analysis, stress relaxation
