Abstract: A pre-rounding element (14) is used in a rounding apparatus (4) for rounding can body blanks from sheet metal blanks. The lower element part (22) of the pre-rounding element (14) is displaceable by an actuation element (23). This allows the adjustment of the pre-rounding element even during operation of the rounding apparatus. Preferably a measurement of sheet metal blank properties takes place. The measurement may include a thickness measurement and/or a strength measurement of blanks. The pre-rounding element is controlled in dependency of the measurement result. This allows a constant rounding result even with varying sheet metal properties.

Abstract: In a wire-processing machine, by a linear movement away from a first holding unit, a gripper applies to a gripping unit a pull-out force in the longitudinal axis of the wire. The pull-out force that is exerted on the wire is measured by, for example, a force sensor that is arranged on the holding unit or by the motor current of the motor that causes the linear movement. The gripper and the gripping unit together make measurement of the pull-out force possible also for medium-sized and large wires without the gripper needing to be constructed stronger, or its dimensions, or the gripper-arm drive, needing to be changed.

Abstract: In order to provide a method and apparatus for forming a sheet metal, in which a three-dimensional product such as a prototype for commercialized press-forming can be formed in short time without limitations as to the shape and with high accuracy, preventing body wrinkles or reduction of the sheet thickness, a process of: performing drawing-forming to a predetermine height by pushing the forming punch having a desired shape in the sheet thickness direction with the edges of the blank workpiece being clamped; performing shape-forming with the shaping tool in the opposite side to the forming punch by increasing a clamping pressure to lock movement of a material with the forming punch being pushed; performing drawing-forming again by decreasing the clamping pressure and raising the forming punch by a desired height; and performing shape-forming with the shaping tool by increasing the clamping pressure to lock movement of a material, is repeated at least once.

Abstract: The invention relates to a marking machine for metallurgical products, more particularly continuous cast products, comprising at least one marking stamp and a striking device for striking the marking stamp into the product to be marked. The striking device is provided with a striking bolt and a striker spring driving said bolt. The striking bolt strikes the marking stamp that is placed in striking position by actuating the striker spring with an actuation element that is driven by an electric motor, thereby hammering the marking stamp into the product to be marked. Every time the marking stamp is subjected to the action of the spring, the stamp receives an evenly high kinetic energy thereby causing an evenly high striking depth of the marking. The spring in association with the electric motor drive enables fast, precise and easily controllable execution of the individual working steps of the machine. The ensures a high marking repetition rate.

Abstract: A hemming machine is disclosed having a base, a nest adapted to support a part to be hemmed, a nest carrier which supports the nest and in which both the nest and nest carrier are vertically movably mounted to the base. At least one hemming die is laterally slidably mounted to the base and movable between an extended position in which the die overlies a portion of the nest, and a retracted position in which the die is spaced laterally outwardly from the nest. A lock unit selectively locks the nest carrier against vertical movement relative to the base in at least one, and preferably two positions, so that, with the nest carrier locked against movement relative to the base, inflation of a hydraulic bladder sandwiched between the nest and nest carrier displaces the nest vertically upwardly from the carrier so that the part carried by the nest is compressed against the hemming dies and performs the hemming operation.

The first and second legs, the base, and the upper platen comprise the elements of a four bar linkage. The linkage is translated from a first position where the first and second legs are parallel and extend vertically upward to a second position wherein the platen is rotated up to 90.degree. or more and is displaced laterally from the base and can face to the side and upward allowing access to the base and the upper platen from overhead.

Abstract: Flat metal strip of indeterminate length is apertured in a punch press having a flying die set to define a lengthwise succession of identical workpiece blanks connected by strap-like portions of the strip adjacent to its longitudinal edges. That press, each time it operates, makes two apertures that define respective end edges of a blank. The strip is pulled lengthwise through that press by roller forming apparatus which imparts a predetermined transverse profile to it and propels it through a flying shear press whereby each blank is severed from the rest of the strip. On a conveyor having two stretches bridged by the severed blank and moving faster than the strip the severed blank is carried to a folding press. There a ram rises from between the conveyor stretches, lifting the blank off of the conveyor and clamping it against a folding die.
