Abstract
In an hydraulic press, usable as a press for forming composite sheet material, with a press base, several vertical guides extending out of the press base and a cross head slidably arranged on the vertical guides, which cross head is hydraulically clampable to the vertical guides, with a slidable press plate and a press drive, wherein several long stroke hydraulic cylinders are provided for adjusting the cross head and several short stroke hydraulic cylinders create the stroke of the press plate. The vertical guides and the cross head are made with several guide laminations clampable together in order to realize a guide and coupling system at small construction expense.
Claims4
An hydraulic press, usable as a forming press for composite sheet material, with a press base, several vertical guides extending from the press base and a cross head slidably arranged on the vertical guides, which cross head is hydraulically clampable to the vertical guides, with a slidable press plate and a press drive, wherein several long stroke hydraulic cylinders are used to produce the adjustment of the cross head and several short stroke hydraulic cylinders create the stroke of the press plate, characterized in that the vertical guides are each made of several vertically extending laminations spaced from one another by spacing means in the press base, in that the cross head includes several other laminations extending into the spaces between said vertically extending laminations, and by means for releasably clamping said vertically extending laminations and said other laminations to one another to releasably clamp the cross head to the vertical guides.
