摘要： Apparatus for feeding a bar or several bars in a vertical pile along a predetermined horizontal path extending through a bending station, where the bars are bent into desired shape. A first conveyor has mounted thereto a first gripper assembly, which releasably grips the bar or bars, for feeding successive requires lengths of the bar or bars to the bending station. Arranged collinearly with the first conveyor, a second conveyor has a second gripper assembly and coacts with the first conveyor for transporting the bar or bars through, and away from, the bending station with the progress of bar bending. The second gripper assembly is further movable up and down on the second conveyor. Upon completion of the bending of the bar or bars, the second gripper assembly grips the bent bar or bars while being lowered, then is raised for lifting the bar or bars out of engagement with the bending mechanism at the bending station, and then is transported by the second conveyor away from the bending station.

摘要： Two pairs of opposed feed rolls are rotatably mounted on the upstream and downstream sides, respectively, of a bar cutting mechanism with respect to the predetermined traveling direction of the bar. Each feed roll pair comprises a fixed feed roll on one side of the bar and a movable feed roll on the other side, with the movable feed roll being movable toward and away from the fixed feed roll. A drive mechanism constantly rotates each pair of opposed feed rolls, so that the bar is fed only when being pressed against the fixed feed roll by the movable feed roll. The feed roll pair on the downstream side of the cutting mechanism is further jointly movable laterally of the path of the bar against the force of a spring for lessening the load exerted thereon, and for preventing the bending of the bar, when the bar is being cut by the cutting mechanism. Each feed roll may be provided with a multiplicity of teeth arranged circumferentially thereon and resiliently biased radially outwardly for positive engagement with a regular pattern of ribs on the bar.

摘要： A press brake adapted to apply bending on metal blanks in the form of a sheet or plate includes a plurality of die assemblies located on a die holder at intervals of a predetermined distance in the direction perpendicular to the logitudinal direction of a bed of the press brake. The die holder is mounted on the bed movably in the direction perpendicular to the longitudinal direction of the bed. Each of the die assemblies is provided with an upper die and a lower die which are associated with each other and movable vertically towards and away from each other. The press brake further includes a pair of front and inside stoppers located on the front side and the inner side of the press brake body, respectively, so as to be movable freely towards and away from each other and pass through a space between the upper and lower dies.
