A system of a separable frame for presses and press frames (), the respective press frame () comprising uprights () and a head piece as an upper cross connection () and a press table as a lower cross connection (), which as structural units form a closed frame that absorbs static and dynamic forces for any required functions of a press such as the drive of a ram used for forming with tools. The uprights () are attachable laterally or longitudinally to the cross connections () by non-positive or non-positive and positive joining geometries () and releasable connector (). The proposed press frames () have a reduced vertical deflection (v) compared to press frames joined by tie rod bracing ().

System of a frame for presses

Proposed is a transfer system for presses, having at least two fastening units arranged opposite one another, wherein each of the fastening units in each case has a first fastening region. The transfer system further has a press transfer unit, consisting of two movement arms arranged opposite one another, as well as a crossbar connected thereto for receiving and for transporting, i.e. including setting down, a workpiece. Each of the movement arms has a first drive unit connected to the first fastening region, a first lever arm, a second drive unit, and a second lever arm. The first lever arm is connected at a first end thereof or between the first and a second end to the first drive unit, and at the second end thereof to the second drive unit. The second lever arm is rotatably connected at a first end thereof to the second drive unit, and is movably connected with a second end thereof to the crossbar. In addition, at least one energy-storing element is provided for each movement arm, which energy-storing element is formed and arranged in such a way that its force or a force component thereof points in the acceleration direction of the crossbar with or without. In an embodiment c1, a second fastening region is provided on the fastening unit, and the energy-storing element is connected directly or indirectly with a first end thereof to the second fastening region, and is fastened on a second end thereof at a specified region of the movement arm. In an additional or alternative embodiment c2, the energy-storing element is fastened with a first end to the first lever arm and with a second end thereof to the second lever arm.

Transfer system for presses and press assembly

A simulation method for optimizing transport displacement of workpieces in transfer presses is provided. Conclusions relating to the freedom of motion, number of strokes and program data for tool-specific machine control are determined by manipulating a displacement curve on a digital image of the transfer press which is determined by the simulation method.
