Abstract:
1. A forging machine comprising: a machine bed including a pair of spaced-apart left and right sidewalls that define a forging space therebetween and that have front and rear ends; a feeding unit disposed at a front end of said right sidewall and adapted to feed a linear material into said forging space; a cutting unit disposed movably on said machine bed and movable reciprocally relative to said machine bed within said forging space along a direction perpendicular to said right sidewall of said machine bed; a forging unit disposed within said forging space in said machine bed and including a female die unit disposed in front of said cutting unit, and a male die unit disposed behind said cutting unit and movable reciprocally within said forging space in said machine bed so as to perform a forging operation; a holding unit including a holder seat disposed swingably on said machine bed behind said female die unit, a driving plate unit disposed behind said holder seat and movable reciprocally along a direction perpendicular to said right sidewall of said machine bed, and a plurality of spaced-apart holders disposed behind said holder seat and driven by said driving plate unit; a driving unit including a first driving mechanism disposed between said left and right sidewalls of said machine bed for driving said forging unit, a driving wheel disposed on an outer side surface of said right sidewall of said machine bed and driven by said first driving mechanism, a second driving mechanism disposed adjacent to said right sidewall of said machine bed and interconnecting said driving wheel and said feeding unit so as to drive said feeding unit, and a third driving mechanism disposed on said right sidewall of said machine bed and driven by said driving wheel so as to open and close said holders, said third driving mechanism including a first rotating rod extending perpendicular to said right sidewall of said machine bed and driven by said driving wheel to rotate, a second rotating rod extending parallel to said right sidewall of said machine bed and driven by said first rotating rod to rotate, a third rotating rod disposed in front of and parallel to said first rotating rod and driven by said second rotating rod to rotate, and a plurality of spaced-apart cams sleeved fixedly on said third rotating rod and aligned respectively with said holders; and a sliding seat unit including
