摘要： To prevent a crack from occurring on a sheared end face due to press forming, a technology is provided for evaluating and predicting a crack limit of the sheared end face of a metal sheet and determining press forming conditions. In a deformation limit evaluation method for, when deforming by press forming a metal sheet subjected to shearing, evaluating a deformation limit of the sheared end face of the metal sheet, the deformation limit is evaluated by an index value obtained from two stress gradients at an evaluation position among stress distributions occurring in the vicinity of the sheared end face of the metal sheet due to the press forming, which gradients are a stress gradient in a sheet thickness direction and a stress gradient in a direction away from the sheared end face.

摘要： Generally trapezoidal web sections of non-uniform shape for fabricating structural I-section beams having varying bending modulus are cut from rectangular plate stock pieces by a shear whose platen is oscillated, as a series of pieces are cut from a length of metal sheet or plate, about an axis perpendicular to the plane of the stock material. The platen angle is determined and controlled by a computer to which design criteria are fed.

摘要： A strip welding machine for butt-welding cut surfaces of a strip beginning and a strip end of metal strips to be connected is described. The welding seam is manufactured with a laser welding head. In order to obtain a plane and parallel and gap-free butt joint of the cut surfaces, two separately mounted cutting tools are provided. Each cutting tool has an upper knife and two lower knives, wherein each upper knife is moved virtually without a gap between the two lower knives. Consequently, the cut surfaces at the strip end and the cut surfaces at the strip beginning of the metal strips to be connected are manufactured with equal cutting forces, so that dimensional inaccuracies cannot occur.

摘要： A blanking shear machine has a rotatable upper turret having a holder for an upper blade. The upper blade has two contiguous sides which form a right angle therebetween. A rotatably mounted lower turret has a holder for a lower blade which corresponds to the upper blade. Means for clamping and positioning a workpiece are provided between the upper and lower turrets. The turrets are rotated to position the blades to provide the desired cut. A plurality of strikers are provided above the upper turret at four positions above the upper blade at which the contiguous sides of the blade are aligned with the X-axis and Y-axis coordinates. Means for actuating the strikers are provided to lower the upper blade to engage the lower blade, shearing the workpiece between the two blades.

摘要： The invention relates to a scrap shearer comprising a displaceable frame (1) and a pair of blade units (2, 3) shearing in a scissor-like manner, whereby the blade units are fastened on the frame (1) so that at least one of the blade units (2, 3) is pivotable. The object of the invention is to provide a scrap shearer which is displaceable to such large scrap objects as e.g. ships and which is capable of advancing within the scrap object, by means of which shearer the requirements of different kinds of scrap objects can be taken into account in the best possible way. This is achieved according to the invention in such a manner that fastening means (7, 8, 11) of the pivotable blade unit (2) are adjustable for the adjustment of the shearing gap and/or angle between the blade units (2, 3).

摘要： The overall arrangement of a number of non-overlapping rectangles with constraints on their size and shape, may be generated with relation to a number of objective functions such as, size and shape of the enveloping rectangle, size of an interconnecting network, and distance between pairs of individual rectangles, by first embedding a distance space, reflecting the desired proximity structure, in the plane; next, by refining containment relations, fixing the relative positions of rectangles within such a containment in accordance with the corresponding positions in the embedding; and on the basis thereof estimating the space required for the local realization of the interconnecting network in a configuration satisfying the constraints on the individual rectangles, and optimal with respect to any quasi-concave objective function on the dimensions of the enveloping rectangle that is monotone in its arguments. The method can be implemented even on relatively small computers. Its major application is in the generation of mask patterns of complex semiconductor integrated circuits, especially when a given functional structure must be preserved by containment in rectangles.
