Abstract (en)

[origin: WO9958265A1] A deep drawing press comprising a lower part (1) that supports the lower part of a tool (7b) and a ram hammer (2) that can move vertically along a guide, whereby said ram hammer supports the upper part of the tool (7a). A drawing cushion (12) that can move vertically in various directions is arranged underneath the lower part of the tool (7b). The movement of the drawing cushion (12) is transmitted to the element that supports the lower part of the tool (7b) and is provided for a drawing sheet (11) by means of drawing rods (9) that are guided in guide holes (1c) in the lower part (1) of the press. The ram hammer (2) is driven by means of two threaded spindles (4) that extend vertically and parallel to each other between the lower part (1) and the ram hammer (2), whereby said spindles co-operate with spindle nuts (5), the rotated drive elements are coupled to each other without any slip and the ram hammer (2) is guided along guiding surfaces that extend vertically and parallel to the threaded spindles (4) and are firmly connected to the lower part (1) of the press. The drawing cushion (12) has an electric motor drive mechanism that works by means of vertically extending threaded spindles (13) and spindle nuts (14), whereby the rotated drive and or driven elements are coupled to each other without any slip.
