摘要： The invention relates to a forming machine, comprising at least one forming station with a die and die plate as tools and a device for the adjustment of the axial position of one of the both tools. Said adjustment device comprises, as adjustment wedge, a rotating wedged disc (1), which rotates about a rotating axis which is supported on a base body (2) by means of a locating face (11). On the other disc face the rotating wedged disc (1) has a skewed plane (12). The adjustment device further comprises a pressure component (3) which is composed of a pressure piece (32) and a rotating piece (30) with a front face (31). The front face (31) lies on the skewed plane (12) in such a way that, on turning the rotating wedged disc (1), said face is displaced relative to the above eccentrically to the rotating axis, which results in a change in the axial separation of the pressure component (3) and the base body (2). As the adjusting wedge is a rotating wedged disc (1), the locating face (11) rotates on the base body (2) and is not longitudinally displaced on making an adjustment.

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.
