The disclosure is not limited in its execution to the previously indicated, preferred exemplary embodiments but rather a number of variants are conceivable which make use of the presented solution even in the case of basically differently designed embodiments. Therefore, the side sliding plates 10, 30 can be designed on at least three side surfaces with a coating against wear, preferably as fixed lubricant surfaces or as a sintered layer.

A first-face forming portion of a workpiece and a second-face forming portion spaced apart from it by the length of an intermediate portion are clamped with a first-face forming die and a second-face forming die, respectively. The first-face forming die is moved either upward or downward and the second-face forming die is moved in a direction toward the first-face forming die, and the second-face forming die is pressed against the first-face forming die to shape the upright wall portion.

A hem punch is floating-supported to a slide cam by a floating-support mechanism. After the hem punch is moved to be positioned at a pre-hemming start position by a driver cam, preliminary hemming is performed. Subsequently, the hem punch is moved to be positioned at a final-hemming start position by the driver cam, and then the hem punch is moved downward by the floating-support mechanism to perform final hemming.

Provided is a cam type press capable of controlling deformation of a flange of a panel in the course of processing the flange, thus reducing deformation such as a crease, or the like, of the flange. The cam type press includes a padding cam installed to be movable in a slope direction. A slider is installed to be movable toward the padding cam, with a process gap into which a portion of a panel is inserted to form a flange between one side of the padding cam and one side of the slider. An adjustment block adjusts the process gap provided between the other side of the padding cam and the other side of the slider.

A slide element for a wedge drive, with a slide element receptacle and a drive element between which the slide element is to be placed. In order to achieve a high wear resistance and a simple design, it is proposed for the slide element to have a head rail, which is detachably fastened to the slide element and, as part of the dovetail-shaped side of the slide element, forms the second sliding surfaces on the dovetail-shaped section, by means of which forces are transmitted during the return stroke during which the slide element receptacle is moved away from the drive element.

Disclosed is a press forming apparatus including a lower die assembly having a lower die, an upper die assembly having an upper die configured to be movable in a first direction relative to the lower die, a cam slider configured to be movable in a second direction relative to the lower die, and a conversion mechanism configured to convert a movement of the upper die assembly in the first direction into a movement of the cam slider in the second direction.

A slider arrangement (1) has a wedge drive tool with a slider upper portion (10) and a slider lower portion (20) which, due to a relative movement with respect to the slider upper portion (10), can be displaced along guides (30) from an initial position into a working position and vice versa. At least one return device (40) is provided in order to bring about the initial position of the slider upper portion (10) and slider lower portion (20), wherein the return device (40) has a screw plug (50) at the end in order to attach the return device (40) in a recess (11) of the slider arrangement (1). The screw plug (50) can have one or at least two rotation prevention part(s) (51) designed to prevent a rotation of the screw plug (50) beyond a maximum acceptable rotation angle .
