A protective arrangement for a drawing press which includes a detector arrangement for detecting at least one of a presence of a workpiece, a semi-finished workpiece, and a correct workpiece feed whereby the drawing press is immobilized or shut down in the event the detector arrangement detects a fault. The detector arrangement is adapted to detect contours of a workpiece which have been drawn by the drawing press and is disposed downstream of a drawing station of the drawing press.

Protective device for a drawing press

Apparatus for stripping hollow articles off of a press ram including a stripper supporting ring extending circumferentially around the press ram, a plurality of segments mounted on said supporting ring for limited radial displacement with respect to the press ram axis, and a plurality of individual hydraulically cushioned strippers mounted in each of said segments for direct engagement with the article to be stripped from the press ram. Various preferred embodiments include various mechanisms for permitting and/or positively providing radial displacement of the segments so as to accommodate passage of the press ram and article to be stripped. Several of these preferred embodiments include biasing means such as springs and/or pressure medium forces for biasing the segments radially inwardly and chamfered conical beveled edges on the segments for accommodating an outward biasing force application by way of the article and press ram. Other preferred embodiments include guide tracks rotatably mounted on the supporting ring for engagement with guide rollers carried by the segments for effecting a positive radial displacement of the segments sequentially timed to coincide with the press operation to prevent radial inward displacement of the segments during other than the stripping operations. In certain of the embodiments using the guide rollers, the guide rollers are maintained in contact with the guide tracks by spring means and/or pressure medium applied forces. In another preferred embodiment, two sets of guide rollers are provided for effecting a positive inward and a positive outward displacement of the segments.
