摘要:
The present invention relates to a system and method for transporting workpieces in forming machines. The system comprises a main carriage (1) and a gripping device (3) configured for gripping a workpiece (P) and attached to the main carriage (1). The gripping device (3) comprises a clamp (31) for gripping the workpiece (P), and a clamp actuator (32) for causing the movement of the clamp (31) so that said clamp (31) closes and/or opens for gripping and/or releasing the workpiece (P). The system comprises a main actuator (2) for linearly displacing the main carriage (1), and a control device configured for acting on both actuators (2, 32) to cause the linear displacement (70) of the main carriage (1) and the movement of the clamp (31) to be generated in a coordinated manner, depending on the diameter of the workpiece (P).

An apparatus to produce a self-piercing and clinch nut includes a first forging die assembly (30), a second forging die assembly (50), a third forging die assembly (70), a transfer mechanism (95), and a controller. The first forging die assembly subjects a blank to first processing. The second forging die assembly is adjacent to the first forging die assembly, and subjects the blank, which has undergone the first processing in the first forging die assembly, to second processing. The third forging die assembly is adjacent to the second forging die assembly, and subjects the blank, which has undergone the second processing in the second forging die assembly, to third processing. The transfer mechanism transfers the blank between two adjacent forging die assemblies among the first to third forging die assemblies. The controller controls operations of the first to third forging die assemblies and the transfer mechanism.

A work transport device for a metal-forming machine comprises a pair of grips (1) which have two non-crossing gripper arms (11, 12) which are pivotable relative to one another and which each have a gripping end (111, 121) for gripping a workpiece (9). Each of the two gripper arms (11, 12) is coupled to a common guide head at the end (114) opposite the gripping end (111, 121) and to a separate link (13, 14) in a central region between the two ends. The two links (13, 14) are each rotatable about a fixed pivot (140). According to the invention, the fixed pivot (140) of the link (13, 14) of the one gripper arm (11, 12) is arranged closer to the other gripper arm (11, 12) than the fixed pivot (140) of the link (13, 14) of this other gripper arm (11, 12). As a result, the two gripper arms (11, 12) are swung outwards to a smaller extent when being swung apart.

The invention relates to a device for producing a lifting and lowering movement for lifting and lowering the cross transfer tongs of a forming machine. Said device comprises a rotating control shaft (1) on which a control cam (2), a counter cam (3) and a spring element cam (4) are mounted. A rotationally mounted double lever (5) has a control roller arm (52), a counter roller arm (53) and an output arm (51). A control roller (54) that rolls out on the control cam (2) is rotationally mounted on the control roller arm (52) and a counter roller (55) that rolls out on the counter cam (3) is rotationally mounted on the counter roller arm (53). The control cam (2) and the counter cam (3) act on the double lever (5) in opposite directions of rotation. A spring element roller (62) that is located on a spring element lever (6) rolls out on the spring element cam (4). A spring element (61) is located on the spring element lever (6), and acts on the double lever (5) in the same direction of rotation as the counter roller (65).
