摘要： In an apparatus for automatically transporting workpieces in a multi-stage forming machine, a tong casing (1) is fitted on a transverse transporting tube (2). The tong casing (1) comprises a tong-casing basic body (10) on which there are arranged exchangeable tong modules (12a, 12b, 12c) each with one set of tongs by means of which a workpiece (W2, W3) can be seized laterally from above. Each set of tongs is connected, via a coupling location (19), to associated transmission means which, are in operative connection with a control shaft (3), mounted rotatably in the transverse transporting tube (2), for controlling the opening and closing movements of the tongs. The operation of transporting, from one forming station (U1, U2, U3) to the adjacent forming station (U2, U3, U4), a workpiece (W2, W3) seized by tongs with pairs of interacting tong grippers (130, 140) and the operation of moving the tongs back take place by the transverse transporting tube (2) moving back and forth. The tong displacement can be adapted to the workpieces (W2, W3) by using tong modules (12a, 12b, 12c) with tongs with suitable leverages.

摘要： An apparatus for producing a lifting and lowering movement for lifting and lowering transverse transporting tongs of a forming machine includes a rotatable control shaft on which a control cam, a counter cam and a spring element cam are fitted. A pivotably mounted double lever has a control roller arm, a counter roller arm and a drive output arm. A control roller, rolling on the control cam, is rotatably arranged on the control roller arm and a counter roller, rolling on the counter cam, is rotatably arranged on the counter roller arm. The control cam and the counter cam act on the double lever in opposite directions of rotation. On the spring element cam there rolls a spring element roller arranged on a spring element lever. Arranged on the spring element lever is a spring element, which acts on the double lever in the same direction of rotation as the counter roller.
