Abstract
A punch press having connecting rods which face away from each other are arranged on the eccentric shaft, and each connecting rod is coupled to a connecting lever. Two toggle joint mechanism units are connected to one connecting lever. Two further toggle joint mechanism units are connected to the other connecting lever extending in the opposite direction. The first named toggle joint mechanism units are connected via pressure columns to a first ram. The second named toggle joint mechanism units are connected via further pressure columns to a second ram. Due to the driving structural members which are arranged symmetrically distributed relative to the eccentric shaft of the punch press and the two rams arrived that thereby, the punch press can feature an extremely long space for receipt of the tools without that the height of the punch press, the allowable rated loading and the moving masses must be held overally large.
