Abstract: A vise with clamping jaws (7,8), which are provided on the frame (1), makes possible a drawing-down motion with respect to a bearing surface (17) for the workpiece (16) when the gripping force is applied via a drive mechanism. The clamping jaws (7,8) have on their side facing toward the workpiece (16) a gripping edge (18,19) or gripping surface and, downwardly adjoining thereto, in each case an undercut surface (20,21), set back with respect to a vertical plane through the gripping edge or gripping surface. The clamping jaws (7,8) are mounted pivotably about horizontal pivot axes (14, 15), which are arranged underneath the bearing surface (17) for the workpiece (16) and on the side of the vertical plane facing toward the workpiece. Restoring springs are designed as tension springs (25,26) and thus for absorbing the gripping forces in the elastic range.

Abstract: Draw-down jaw for fitting in vises equipped with a bearing jaw (6) and a clamping jaw (7), the clamping jaw being able to execute a drawing-down motion with respect to the bearing jaw for applying the gripping force. The clamping jaw (7) is mounted on the bearing jaw (6) pivotally about a horizontal pivot axis (8), which is arranged in the upper region of the bearing jaw (6). The clamping jaw (7) has on its side facing toward the workpiece (4) a gripping edge (9) or gripping surface, to which their adjoins upwardly a plane gripping surface (10) and downwardly a free surface (11). The restoring springs are designed as compression springs (12) and thus for absorbing the gripping forces in the elastic range.
