Abstract

In a bending machine for bending metal plate work so as to have four U-shaped rims, there are provided a ram (13) having a lower end, a bottom tool (16), a top tool body mounted on the lower end of said ram (13) above the bottom 16, the top tool body carrying central and corner die segments (1A, 1B, 7A, 7B) engagabe with the work piece (90) for bending it. Difficulties occur upon lowering and lifting the top tool past the U-legs of the rims already bended. For overcoming these difficulties, each corner die segment (7A, 7B) includes a main body (71, 101) and an openable die segment portion (72, 102, 110); a link (75, 103) mounted inside the lower portion of the main body of the upper corner die segment supports pivotably about a generally horizontal axis the openable die segment portion on the end of the link; and a rod (88) is erected on the center of the upper surface of the openable die segment portion to be inserted into a guide hole (89) in the corner die segment main body.
