Forming machine, particularly ring-rolling machine
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.
1. A forming machine comprising:
(a) a radial roll stand carrying radial rolling rollers;
(b) a radially displaceable mandrel lifting apparatus disposed on said radial roll stand being radially displaceable with respect to said radial roll stand by way of a drawing frame;
(c) an axial roll stand carrying axial rolling rollers;
(d) at least one hydraulically regulated linear axle regulated via an electro-hydrostatic actuator;
(e) a control electrically coupled to said electro-hydrostatic actuator;
(f) an electro-hydrostatic direct drive comprising a housing and hydraulics disposed within said housing, said electro-hydrostatic drive comprising the electro-hydrostatic actuator, wherein the at least one hydraulically regulated linear axle is coupled to the electro-hydrostatic actuator, and the electro-hydrostatic actuator controls a movement of the at least one hydraulically regulated linear axle; and
(g) a hydraulic oil tank coupled to the electro-hydrostatic actuator.
2. The forming machine according to claim 1 , further comprising a further drive and at least one further hydraulically regulated linear axle.
3. The forming machine according to claim 2 , wherein the further drive comprises the at least one further hydraulically regulated linear axle.
4. The forming machine according to claim 1 , wherein the forming machine is a rolling machine.
5. The forming machine according to claim 1 , wherein the forming machine is a forging machine.
6. The forming machine according to claim 5 , wherein the forming machine is a radial forging machine.
7. The forming machine according to claim 4 , wherein the rolling machine is a ring-rolling machine.
