Abstract
A forging machine is described having at least one clamping head (6) for a work-piece (5) and having a rotational drive, which is controllable in dependence on the engagement of the forging tools (3), for the clamping head (6). To provide advantageous drive conditions, it is proposed that the rotational drive comprise at least one hydraulic motor (11), which is connected to a pump circuit (12), and which is connected to a hydraulic circuit (17), which is connected in parallel to the pump circuit (12), for the periodic supply and discharge of a predefined quantity of hydraulic medium in dependence on the stroke frequency and/or the stroke location of the forging tools (3).
Claims6
A forging machine comprising:
- (a) at least one clamping head for a workpiece;
- (b) a plurality of forging tools;
- and
- (c) a rotational drive for the clamping head controllable in dependence on engagement of the forging tools;
- wherein the rotational drive comprises a pump circuit, a hydraulic circuit connected to the pump circuit, and at least one hydraulic motor connected to the pump circuit and to the hydraulic circuit;
- wherein the hydraulic motor periodically supplies and discharges a predefined quantity of hydraulic medium;
- and
- wherein the predefined quantity of hydraulic medium is periodically supplied or discharged in dependence on at least one of stroke frequency and stroke location of the forging tools.
