Adjustable crankshaft eccentricity mechanism for lamb stroke modification of body maker

摘要

SolutionThe body Maker 10 includes a rotary crankshaft 600 including an offset crank 602 and an adjustable eccentric assembly 620, and an adjustable eccentric assembly 620 includes an eccentric shell assembly 630.The eccentric shell assembly 630 is operatively coupled to the crank 602 of the crankshaft.The primary connection rod 300 is operatively coupled to the eccentric shell assembly 630.The ram assembly 12 is operatively coupled to the primary connecting rod 300.The ram assembly 12 includes an elongated ram.In this configuration, the ram reciprocates over the stroke, which is a function of the orientation of the eccentric shell assembly 630.Furthermore, in an exemplary embodiment, the ram assembly 12 is configured to adjust the reach distance of the stroke of the ram body 30 through the die pack 16 without substantially separating the many main components.Diagram
