Abstract
A sort of hydraulic deep-draw device for the pressing, having a fixed and tightened punching hammer, a sheet metal holder supported by the hydraulic cylinder tools, the draw punch head, guided by the inward deep-draw and the pull punch plate supported hydraulically for the drawing of metal sheets; with a plurality of mechanic punch pins on top of the draw punch plate and in the scanning field of the machine plate and in the draw punch head profiles being jointly supported by the draw punch onto the draw punch plate, where the draw punch plate is fixed by one or more hydraulic adjustment elements for vertical movement, featuring: a) a draw-pad plate (11), attached below the holding plate (10) of the sheet metal, with multiple of the short-stroke cylinders (13) in multi-point control corresponding to the draw-ring plate (draw punch contour), (b) the press of double-acting type, in which the punch (13) moves downward until short before the contact with the work piece (19) and locked in the force and form fitting way with the pressing frame (7) corresponding to a gap distance on about 0.5mm to 5mm, (c) the short-stroke cylinders activated b hydraulic press in their field of the acting force of the respective ranges of the tension and compression deformation, in order to bridge the gap n, so that the work piece (19) can press against the draw-ring plate (8); and (d) the draw-punch plate (18) can make the draw punch (9) to execute and accomplish the deep-draw deforming stroke (H) by means of the draw-punch pins (17).
