Abstract
A forming machine, particularly a ring-rolling machine, which includes a hydraulically regulated linear axle, which is driven by way of an electro-hydrostatic actuator, can work precisely while having a simple mechanical-engineering structure. The machine may have at least one further hydraulically regulated linear axle, which is driven by way of an electro-hydrostatic actuator or by way of a drive other than an electro-hydrostatic actuator.
Claims20
A forming machine comprising:
- (a) an electro-hydrostatic actuator;
- and
- (b) at least one hydraulically regulated linear axle driven by way of the electro-hydrostatic actuator.
A ring-rolling machine comprising:
- (a) a radial rolling roller having a first radial roller roll shaft acting in a radial direction;
- (b) at least a first radial drive connected to interact with the first radial roller roll shaft;
- (c) an axial rolling roller having a first axial roller roll shaft acting in an axial direction;
- and
- (d) at least a first axial drive connected to interact with the first axial roller roll shaft;
- wherein at least one of the first radial drive and the second axial drive comprises a first motor having a high torque and connected to interact with the first radial roller roll shaft or the first axial roller roll shaft, respectively, without a gear mechanism.
