Workpiece manipulator

Abstract

A workpiece manipulator (1) for use with a radial forging press includes workpiece tongs (4). The workpiece tongs (4) are fastened to a manipulator frame (2) guided linearly on a manipulator track. The workpiece tongs (4) form a chuck with a fixed clamping axis (5) which extends in the forging axis or parallel to the forging axis. The workpiece can be manipulated with a linear translational movement. The manipulator frame (2) is rail-bound on wheels (12) during the translational movement.

Claims

A workpiece manipulator (1) for use with a radial forging press, comprising: workpiece tongs (4), the workpiece tongs (4) being attached to a manipulator frame (2) guided linearly on a manipulator track, and the workpiece tongs (4) forming a chuck with a fixed clamping axis (5), which extends in a forging axis, so that a workpiece can be manipulated with a linear translational movement, wherein the manipulator frame (2) is guided rail-bound on wheels (12) during the linear translational movement.

2. The workpiece manipulator (1) according to claim 1, wherein the manipulator frame (2) comprises a chassis which is spring-loaded and/or damped.

3. The workpiece manipulator (1) according to claim 2, wherein the chassis comprises a plurality of wheel groups.

4. The workpiece manipulator (1) according to claim 3, wherein the wheel groups each comprise at least one wheel carrier (9,10) with a plurality of wheels (12).

5. The workpiece manipulator (1) according to claim 4, wherein the wheel carriers (9,10) are each articulated pivotably on the manipulator frame (2).

6. The workpiece manipulator (1) according to claim 3, wherein at least two front wheel groups are each provided with spring and/or damper elements (13).

7. The workpiece manipulator (1) according to claim 4, wherein each running wheel carrier (9,10) is supported with a plurality of spring and/or damper elements (13) on the manipulator frame (2).

8. The workpiece manipulator (1) according to claim 1, wherein the workpiece tongs (4) comprise a plurality of tongs jaws (6) arranged at equal distances on a radius around the fixed clamping axis (5).

9. A system for manipulating a forged workpiece on a radial forging press, comprising: the workpiece manipulator (1) according to claim 1; and the manipulator track, having with at least two guide rails laid in a floor level (7).

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0027] FIG. 1 is a schematic representation of the workpiece manipulator.

[0028] FIG. 2 shows a detailed view of parts of the chassis of the workpiece manipulator from FIG. 1.

DETAILED DESCRIPTION

[0029] The workpiece manipulator 1, which is designed as a forging manipulator for a radial forging press, comprises a manipulator frame 2 with a tongs carrier 3 with workpiece tongs 4 attached to it. The workpiece tongs 4 comprise four tong jaws 6 arranged at equal distances from one another on a radius around a fixed clamping axis 5. When actuated, the jaws 6 perform a synchronous opening and closing movement in the same direction with respect to the clamping axis 5.

[0030] The workpiece manipulator 1 can be moved linearly on a floor level 7 in front of a radial forging press, not shown, with the clamping axis 5 of the workpiece manipulator 1 extending within the forging axis of the radial forging press. The workpiece, not shown, in the form of a billet to be forged or an ingot is held at the end by the workpiece tongs 4 and fed to the radial forging press via a linear displacement movement of the workpiece manipulator 1.

[0031] The workpiece gripped with the workpiece tongs 4 or the forging billet, which was previously lifted out of a furnace at forging heat to the height of the forging axis and then clamped by the workpiece tongs 4 in the forging axis or in the clamping axis 5, can be moved via a linear movement of the manipulator frame 2 on a guideway 8 during the forging process only linearly according to the translational movement of the manipulator frame 2. In addition, the workpiece tongs 4 can be rotated about the clamping axis 5. The manipulator frame 2 includes a chassis that includes two first front wheel carriers 9 and two second rear wheel carriers 10. The wheel carriers 9, 10 are articulated on the manipulator frame 2 such that they can pivot about a pivot axis 11 of the latter and each comprise four running wheels 12 (see detailed view according to FIG. 2).

[0032] The running wheels 12 are each supported on a guideway 8 designed as a guide rail. The first front wheel carriers 9 are also supported against the manipulator frame 2 via spring/damping elements 13. The second rear wheel carriers 10, on the other hand, are articulated on the manipulator frame 2 in an unsprung manner.
