Abstract: A forming machine has a shearing device for shearing a bar. This shearing device comprises a fixed blade, with a passage for feeding through the bar to be sheared, and a shearing part which can be moved forward and backward parallel to the fixed blade. The shearing part comprises a first shearing blade, with which a bar section projecting from the fixed blade can be sheared in a forward movement of the shearing part, and a second shearing blade, with which a bar section projecting from the fixed blade can be sheared in a backward movement of the shearing part. In addition, the forming machine has a disposal point, to which the second shearing blade transports, as scrap pieces, all the bar sections sheared by it. Due to scrap pieces being sheared solely by means of the second shearing blade, empty places in the forming stations and the associated disadvantages can be avoided.

Abstract: In a method of cutting high-tensile workpieces, in particular sheet metals of martensite steel, the workpiece is subjected to a bending stress prior and during a shearing process. The bending stress causes a substantial component of a tensile force transverse to a desired cutting contour. Tensile stresses are superimposed to the shearing stresses, which favor the beginning of the workpiece separation. The bending stress is preferably selected so that the resulting tensile stress exists at a side facing the cutting tool.

Abstract: A plurality of successively spaced notches are formed in a side edge of a metal strip by first and second adjustably positionable dies prior to roll forming of the strip to a formed configuration. After roll forming, fingers engage selected edges of the notches to detect a notch length dimension and a full part length dimension. Sensors detect the position of the fingers and generate output signals to a controller which generates an adjustment signal based on the switch conditions to adjustably position the first and second dies to accommodate any elongation of the metal strip during roll forming.

Abstract: In blade holding devices sleeves are arranged concentrically about the blade securing screws, in order to relieve the blade securing screws from lateral shearing force components and vertically acting stripping forces resulting, when the blade slide is moved upward, from the friction between the blade and the scrap metal in the feed channel. For the removal of the blade, lateral wearing plates in the feed channel have to be removed. In order to permit the removal of the blade from the holding device without dismantling the wearing plates of the feed channel and, at the same time, retaining the sleeves, a short sleeve is provided, that, in an operational position of said scrap cutter, ascertains form-locking between the blade and the blade slide or the blade support and rests against a long spacing sleeve that is concentrically arranged about a shaft of the blade securing screw and is held by the blade securing nut. The short sleeve is also concentrically arranged about the shaft of the blade securing screw. After removal of the blade securing screws, the short sleeve may be slid toward the backside of the blade, permitting the removal of the blade in a downward direction. A dismantling of the lateral wearing plates is unnecessary.

Abstract: A plate processing device for use in a machine with a vertically acting ram; has a guide device mounted on the frame and a guide member which is pressed to a sliding surface of the ram. The guide member freely rotates around the centerline of the first vertical shaft and also freely rotates around the centerline of the second shaft perpendicular to the first shaft and parallel to the sliding surface and is constructed so that it follows the sliding surface of the ram. Also, a back gauge for the work is buffered against the shock of abutment with the workpiece and may be backed away from the workpiece. A pressing plate for the workpiece is supplied by a high pressure and a low pressure plunger, which are vertically actuated to provide a noiseless operation.
