Abstract: An impact absorbing member comprises a first main body and a second main body. The first main body comprises a first partial tube wall and first flange members. The second main body comprises a second partial tube wall and second flange members. The first flange members are joined with the respective second flange members in a discontinuous manner along the axial direction of the tube. In at least one segment where the first flange members and the second flange members are not joined in the axial direction of the tube, spaces are formed between ends part of a first partial tube wall side of the first flange members and end parts of a second partial tube wall side of the second flange members.

Abstract: The present application provides a technique for simultaneously bending and drawing. In a stamping device, the timing at which an upper pad moves downward and grips a work piece between the upper pad and a first supporting surface is adjusted so as not to be later than the timing at which an upper bending steel makes contact with the work piece. The height of a lower end of the upper bending steel after the timing at which the upper bending steel has made contact with the work piece, and the height of a lower surface of a drawing pad after the timing at which the work piece has been gripped between the drawing pad and a third supporting surface are adjusted such that the lower end of the upper bending steel and the lower surface of the drawing pad move downward while maintaining the same height at a boundary between the upper bending steel and the drawing pad.

Abstract: In a conveying apparatus for conveying works between a first lower die and a second lower die in a press machine, a distal end portion of a multi-joint robot is connected to a linear shaft body, and the linear shaft body carries a linearly reciprocating body movable in the directions of the length of the linear shaft body. The linearly reciprocating body is connected to a first detachable holding device that holds a first work. The linear shaft body is connected to a second detachable holding device that holds a second work. The first work is transferred by motion of the linear shaft body and the motion of the linearly reciprocating body carrying the first holding device, and the second work is transferred by motion of the linear shaft body alone.
