Machine tool for the simultaneous the outside hock pressure forming of the sinkers

摘要

From two mould halves (1, 2) constructed machine tool for the simultaneous external hydroforming of a plurality of circuit boards (12, 13), which at their edges between the in the manner of a press together movable tool halves (1, 2), can be clamped, wherein for each blanks to be formed (12, 13) which a tool half (1) a pilot- form punch (15, 16, 17, 18) and the other half of the tooling (2) a with a the printed circuit board (12, 13) supporting the action medium filled mold cavity (3, 4, 5, 6), and wherein for each of the male tool (15, 16, 17, 18) and the mold cavity (3, 4, 5, 6) existing deformation unit, between the tool halves (1, 2) is effective in such a way, pressure medium (19, 20, 21, 22, 23, 24, 25, 26, 27) are provided, that each mold cavity (3, 4, 5, 6) in a is in its axial position of the flow edge (3a, 4a, 5a, 6a) subsequent circumferential region with respect to the clamped edge of the printed circuit board (12, 13) is sealed.
