摘要： 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.

摘要： The invention relates to a tool-positioning device (22) for at least two tool positions (19, 20) for at least one tool set (10, 11) comprising a tool clamping adapter (16) and at least one bending tool (15), wherein said tool positions can be optionally fixed in the direction of a length (18) of a tool bar (2) of a bending press (1). The tool bar (2) comprises for each tool position (19, 20) a pair of claw-shaped positioning elements that are spaced apart in the direction of the length (18) of the tool bar (2) and are spaced from each other by an adjustment range (55) of the tool set (10, 11). The tool clamping adapter (16) is adjustably mounted in a holding slot (32) running in the direction of the length (18) of the tool bar (2) and comprises a pair of positioning means that can be brought into engagement with the positioning elements in the respective tool position (19, 20).
