ABSTRACT:
The present invention relates to a mould (42) for bending material parts, the mould (42) comprising opposite first and second longitudinally extending mould halves (1, 21) enclosing a longitudinal mould cavity (59). The first mould halve (1) comprises a plurality of parallel first plates (2), and the second mould halve (21) comprises a plurality of parallel second plates (22). The first and second plates (2, 22) extend in width direction of the mould (42), alternate in longitudinal direction of the mould (42) and comprise respectively a first and second end wall (5, 25). Consecutive first and second end walls (5, 25) form respectively first and second side walls (3, 23) on opposite sides of the mould cavity (59). Consecutive first plates (2) are positioned at a distance from each other such as to receive in a first space (20) between adjacent first plates (2) at least part of a second plate (22), and consecutive second plates (22) are positioned at a distance from each other such as to receive in a second space (40) between adjacent second plates (22) at least part of a first plate (2). Each first plate (2) comprises a first bottom part (8) and each second plate (22) comprises a second bottom part (28), the first and second bottom parts (8, 28) protruding from the first and second end wall (5, 25) towards the mould cavity (59) and comprising respectively a first and second end part (10, 30). Further, each first plate (2) comprises means (11) which co-operate with the bottom part (28) of an adjacent second plate (22) for restricting the canting of an adjacent second plate (22) in such a way that the second end part (30) would be moved in height direction of the mould (42), and each second plate (22) comprises means (31) which co-operate with the bottom part (8) of an adjacent first plate (2) for restricting the canting of an adjacent first plate (2) in such a way that the first end part (10) would be moved in height direction of the mould (42), when pressing a material part in the mould cavity (59) for the purpose of bending the material part.
