Abstract

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.

Abstract

The invention relates to a device for transporting workpieces in three axes within a transfer press which has a plurality of tool stages, wherein the device has two mutually opposite transport bars formed in one piece which are movable in the three axes and which remain in the transfer press during an automatic or partially automatic tool change, and an adapter rail per transport bar, wherein each adapter rail is releasably fastened to the associated transport bar. Also provided is at least one tooling per adapter rail, wherein each tooling is directly releasably fastened to the associated adapter rail. Alternatively, at least one tooling rail is provided to which the tooling is indirectly releasably fastened. Here, only adapter rail with tooling or adapter rail with tooling rail and tooling are moved out of the transfer press during the automatic or partially automatic tool change.

Abstract

A system of a separable frame for presses and press frames (1), the respective press frame (1) comprising uprights (2) and a head piece as an upper cross connection (3) and a press table as a lower cross connection (4), 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 (2) are attachable laterally or longitudinally to the cross connections (3, 4) by non-positive or non-positive and positive joining geometries (5) and releasable connector (5.1). The proposed press frames (1) have a reduced vertical deflection (v2) compared to press frames joined by tie rod bracing (6).

Abstract

The invention relates to a transfer system for presses, comprising at least two securing units arranged opposite one another, wherein each of the securing units has a respective first securing region. The transfer system also has a press transfer unit, consisting of two movement arms arranged opposite one another, as well as a connected crosspiece for receiving and for transporting, i.e. including setting down, a workpiece. Each of the movement arms has a first drive unit secured to the first securing region, a first lever arm, a second drive unit and a second lever arm. The first lever arm is connected to the first drive unit at its first end or between the first and a second end, and connected to the second drive unit at its second end. The second lever arm is rotatably connected to the second drive unit at its first end, and moveably connected to the crosspiece by its second end. In addition, at least one energy-storing element is provided for each movement arm, which is designed and arranged in such a way that its force or a force component thereof points in the acceleration direction of the crosspiece with or without the workpiece. In one embodiment c1, a second securing region is provided on the securing unit and the energy-storing element is directly or indirectly connected to the second securing region by its first end and secured to a predefined region of the movement arm at its second end. In an additional or alternative embodiment c2, the energy-storing element is secured to the first lever arm by a first end and to the second lever arm by its second end.

Abstract

The invention relates to a system of a divisible frame for presses and correspondingly designed press frames (1), wherein each press frame (1) comprises side pillars (2) and a head piece as an upper cross-connection (3) and a platen as a lower cross-connection (4), which, as structural units, form a closed frame, absorbing static and dynamic forces, for any required functions of a press, such as driving a ram for forming by means of tools. The side pillars (2) can be secured laterally or longitudinally to the cross-connections (3, 4), by means of force-locking or force-locking and form-locking joining geometries (5) and detachable connection means (5.1). The press frames (1) according to the invention have a reduced vertical deflection (v2) compared to press frames joined by way of tension rod bracing (6).
