072453170 Riveting tool 2
20110048099HAND-TOOL SYSTEM FOR INSTALLING BLIND FASTENERS - A tool for setting blind fasteners is disclosed. A stem of a fastener is engaged by a pulling head and its sleeve is also engaged by the pulling head. In an initial stage, a pump piston compresses fluid in a hydraulic pump, affecting movement of a drawbar and piston in relation to a stationary adaptor connected to the tool, pulling the stem in relation to the sleeve at a fast rate per pump. As the pulling force increases, pressure in the pump triggers a logic system to shift the tool into a high pressure mode, decreasing the effort to complete fastener installation. The logic system resets after each squeeze of the lever, minimizing the number of pumps necessary to complete the installation while keeping effort at a comfortable level. An adjustable pressure relief valve allows the fluid to return to the reservoir chamber, returning the tool to its initial condition.03-03-2011

20140366606DIE CUSHION FORCE SETTING APPARATUS - The die cushion force setting apparatus according to an aspect of the present invention allows die cushion forces (component forces) acting on plural driving shafts to be set easily, makes it easy to apply strong or weak die cushion forces to a complex-shaped drawn part in a plane of a cushion pad, and provides a smooth die cushion force distribution. An operator manually enters a total die cushion force, axial component force of a left front hydraulic cylinder, and center-of-force position by operating an input device. Based on the information entered via the input device, the numerical computing device B1 calculates axial component forces of three hydraulic cylinders through numerical computations. The one axial component force thus entered and three axial component forces thus computed numerically are set as the axial component forces of four hydraulic cylinders.12-18-2014
