Abstract:
In a multistep bending machine, a movable apron (LA) provided with a movable tool (D) is moved in a multistep manner up and down toward a fixed apron (UA) provided with a fixed tool (P) by a hydraulic system including a novel die-axis drive mechanism (DDM), when a foot switch (FS) is kept depressed.In addition, an interference prevention device (IPA), a bending speed determining device (SDA), a tool distance determining device (TDA), a backgage stopper positioning device (SPA), and a backgage stopper pull-back distance controlling device (PDC) are all incorporated in the bending machine to realize a full automatic multistep bending operation.
Abstract:
In a bending press, the stroke length of a ram member is automatically set based upon conditions such as the angle to be made on a workpiece, the width and configuration of a groove in a lower tool, and the thickness, width and tensile strength of the workpiece. There is also an input device into which the bending conditions are set and a computer for calculating the stroke length of the ram member which is then automatically adjusted. A device for detecting deflections occurring in an overhead beam in the bending press is connected to the computer to compensate for the stroke lengths of the ram member. The press accurately and easily bends sheet-like workpieces into various shapes including those cylindrical and semicircular in cross section.
Abstract:
A lead 3 of an electrochemical device includes a lead body 3A containing Al, and a bent metallic thin film 3a provided to a tip part of the lead body 3A. The metallic thin film 3a includes a thin film body 3a1 containing Ni, and a plating layer 3a2 containing Sn and covering at least an outer surface of the bent thin film body 3a1. A specific area of an inner surface of the bent thin film body 3a1 and a surface of the lead body 3A are welded in a predetermined area without the plating layer 3a2 being disposed there between.
