  • Patent number: 10894282
    Abstract: A tool for manufacturing blanks and a process for stacking and destacking the blanks in a production line are provided. The tool is incorporated into a blanking die used to trim a metal sheet and form the blanks. When the blanks are stacked, the destacking formations provide gaps between the adjacent blanks. The gaps provide an entry to blast air and thus reliably separate the blanks for pick up, so that only one blank is picked up at a time. The tool includes a deforming unit that has an engagement element for pressing deformations into the metal sheet. The deformations are pressed adjacent to at least one edge of the metal sheet so that when the metal sheet is trimmed, and the blanks are stacked, they are spaced by the deformations by adjacently stacked blanks.

  • Patent number: 10864573
    Abstract: A part of kinetic energy during lowering of a slide of a press machine is converted into oil hydraulic energy by a first oil hydraulic cylinder, and the converted oil hydraulic energy (hydraulic oil having boosted first system pressure) is stored in a first accumulator. The hydraulic oil having the first system pressure stored in the first accumulator is discharged in knockout process, a second oil hydraulic cylinder that functions as a knockout cylinder is raised to perform knockout operation of a product worked by the press machine. Consequently, it is possible to perform knockout operation without using a dedicated driving source such as an oil pressure source and an air pressure source, and provide a low-cost hydraulic knockout device.
