摘要： 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).

摘要： A device for the automatic conveyance of workpieces on a multistage metal-forming machine tool with a tong case (1) located on a cross conveyor tube (2). Tong case (1) comprises a base body (10) on which interchangeable tong cartridges (12a, 12b, 12c), each with a pair of tongs enabling workpiece (W2,W3) to be gripped laterally from above, are placed. Each pair of tongs is connected via a coupling point (19) to means of transmission associated thereto. Said means interact with a control shaft (3) which is placed rotatably in the cross conveyor tube (2) to control opening and closing movement of tongs. Conveyance of a workpiece (W2, W3), grasped by one pair of tongs with twin interacting grippers (130, 140), from one metal-forming station (U1,U2,U3) to a neighbouring metal-forming station (U2,U3,U4) and the return movement of the tongs occur when the cross conveyor tube (2) moves back and forth. Tong travel can be adapted to workpieces by using tong cartridges (12a,12b, 12c) with tongs having appropriate lever ratios.
