An arrangement for the transport of workpieces in a multi-stage deformation press in which the workpieces are to be seized by gripping tongs and are to be transferred in the deformation stages. The gripping tong consists essentially of a base body which is displaced in the direction of a deflection movement by way of a coupling rod. The base body carries a pivot support in which the gripping arms are rotatably supported in pivot joints. The areas of the gripping arms remote from the workpiece are pivotally connected at the base body by way of a coupling member. Within the area of the pivotal connection, the gripping arms carry rollers which are placed from the outside against curved regions of a cam plate by way of a compression spring between the base body and the pivot support. One cam region is on the shape of a circular arc about the pivot bearing so that a larger closing and opening movement is imposed on the gripping arms.

Arrangement for transporting workpieces in multi-stage deformation

An apparatus for the intermittent feeding of web-type or strip-type material by means of feed roll into an operating chamber of a press. The feed rolls are driven by a main press drive through a mechanical connection and a feed gear mechanism. A scrap cutter is provided which can be driven in correspondence with the operating cycle of the press. The mechanical connection can be selectively severed or interrupted with an auxiliary drive mechanism being provided which is adapted to be connected to the apparatus. The scrap cutter may be driven by a separate drive mechanism in correspondence with the cycle of the feed gear mechanism.
