A method for stamping and stacking sheet metal parts (2) to form lamination stacks (3) is disclosed. In order to facilitate the separation of joined sheet metal parts (2) into lamination stacks (3), a second stamping-out of at least one second sheet metal part (20) is performed in a step preceding the first stamping-out, as well as a pushing-back of the separating element (19) into a region of the electrical steel strip (5) from which the second sheet metal part (20) has been stamped and a pushing-out of the separating element (19) from the electrical steel strip (5) with the first stamping-out.

A metal processing apparatus comprising: (i) a first tool portion including a first carrier, a cutting surface, a first plurality of dimple forming elements; (ii) a second tool portion including a second carrier, in opposing relation to the first tool portion, the second tool portion having a blade or adapted to receive the blade which is adapted to contact the cutting surface for cutting an edge of a metal sheet to form a cut edge in the metal sheet, a second plurality of dimple forming elements; and (iii) a dimpler indexer to index the first plurality of dimple forming from a first pre-determined location to a second pre-determined location. The metal processing apparatus may find particular use in creating dimples along one or more cut edges of a metal sheet to allow for stacking of the metal sheets with an airgap therebetween.

An integrated flattening, cutting, and collecting assembly includes a frame, a conveyor seat, and a processing rack. The processing rack is provided with a flattening cylinder and cutting cylinders, a flattening block cooperating with a steel sheet being conveyed by the conveyor seat, a cutting lift seat disposed beneath the cutting cylinders, the cutting lift seat being provided with a cutter and cutting pressing blocks, and wherein the distance between the two cutting pressing blocks is smaller than the length of the flattening block. In addition, the lower end of the cutter is disposed beneath the lower ends of the cutting pressing blocks, and this distance is the same as the thickness of the steel sheet being conveyed. The cutting pressing blocks can press and hold the steel sheet during cutting, while not affecting the cutting of the cutter, whereby the accuracy of the steel sheet cutting is greatly improved.

According to some embodiments a conveying device for conveying goods includes at least one conveyor belt with an outer contact face against which the goods to be conveyed are held during conveyance. A main negative pressure holding area is provided adjacent to the conveyor belt, the main negative pressure holding area being configured to hold or release the goods to or from the conveyor belt by negative pressure. The conveyor belt includes at least one suction chamber on the outer contact face forming an additional negative pressure holding area, the suction chamber being in fluid communication with negative pressure holding means through at least one opening transversely going through the conveyor belt.

A workpiece placement platform device including: an X-axis direction positioning member provided on one side of a placement platform on which to place a plate-shaped workpiece and configured to position one side edge of the workpiece in an X-axis direction by contacting the one side edge; a Y-axis direction positioning member provided on another side of the placement platform and configured to position another side edge of the workpiece in a Y-axis direction by contacting the another side edge; and a workpiece positioning member that is movable in and out relative to a workpiece placement surface of the placement platform and configured to partition the workpiece placement surface into sections in the X-axis direction and enable simultaneous positioning at the sections on the workpiece placement surface.

A key blank loading cartridge includes a sleeve defining a cavity for holding a stack of key blades within a box of key blanks. The key blanks are releasably retained in the cartridge cavity by their blade portions leaving the head portions of the blanks exposed. After having been removed from the box, the so retained stack of key blanks is ready to be loaded as a single unit in a corresponding key blank magazine. Once the head portions of the key blanks have been engaged in the magazine, the sleeve can be pulled off the blanks and returned to the key blank manufacturer and reused in another key blank shipping package.
