Forming equipment for rolling and profiling disk-shaped and ring-shaped parts

Abstract

The invention relates to forming equipment for rolling and profiling disk-shaped and ring-shaped parts of a metallic material, e.g., of steel, of super alloys, aluminum alloys, etc., whereby a pressure rolling device without its own axial drive designed as a transportable and replaceable construction unit that it can be replaceably mounted in a conventional forging press between a press ram and the press bed plate for axial rolling. Because of this, the investment costs for otherwise conventional pressure rolling machines is reduced considerably and current forging presses can be used without remodeling for axial rolling by integrating a pressure rolling device according to the invention.

1 . Forming equipment for rolling and profiling disk-shaped and ring-shaped parts wherein a pressure rolling device ( 4 ,  5 ,  6 ,  7 ,  8 ,  9 ,  10 ,  11 ,  12 ) without its own axial rolling drive is mounted, as a transportable and replaceable construction unit, in a conventional forging press ( 1 ) between a press ram ( 2 ) and a press bed plate ( 3 ), whereby the press ( 1 ) applies the axial rolling force.  
     
     
         2 . Forming equipment according to  claim 1 , characterized in that the press bed plate ( 3 ) can be moved in horizontal direction and holds the pressure rolling equipment ( 4 ,  5 ,  6 ,  7 ,  8 ,  9 ,  10 ,  11 ,  12 ) and that an upper machine housing ( 10 ) of the pressure rolling equipment ( 4 ,  5 ,  6 ,  7 ,  8 ,  9 ,  10 ,  11 ,  12 ) is guided mechanically so that it can be adjusted and is connected with a lower machine housing ( 5 ) of same.  
     
     
         3 . Forming equipment according to  claim 2 , characterized in that the mechanical connection is produced with several, preferably four, column guides ( 4 ) with return traverse, which are tightly connected to the upper machine housing ( 10 ) of the pressure rolling equipment ( 4 ,  5 ,  6 ,  7 ,  8 ,  9 ,  10 ,  11 ,  12 ) and that are guided in corresponding recesses of the lower machine housing ( 5 ) so that they can move by sliding.  
     
     
         4 . Forming equipment according to  claim 1  or one of the following claims, characterized in that all the energy supply lines for the pressure rolling equipment ( 4 ,  5 ,  6 ,  7 ,  8 ,  9 ,  10 ,  11 ,  12 ) for electrical energy, hydraulic energy, for cooling and lubrication, as well as for control are connected with quick connects, especially with plug connectors.  
     
     
         5 . Forming equipment according to  claim 1  or one of the following claims, characterized in that the pressure rolling equipment ( 4 ,  5 ,  6 ,  7 ,  8 ,  9 ,  10 ,  11 ,  12 ) has its own control and hydraulics and is only linked to press ( 1 ) by signals in such a way that press ( 1 ) is fully functional without integration of the pressure rolling equipment ( 4 ,  5 ,  6 ,  7 ,  8 ,  9 ,  10 ,  11 ,  12 ).  
     
     
         6 . Forming equipment according to  claim 1  or one of the following claims, characterized in that depending on the workpiece temperature measured in the rolling slot, the feed of the press ram ( 2 ) can be controlled in such a way that the forming temperature is constant or nearly constant over the entire rolling process, especially for high-temperature-resistant materials, e.g., steel alloys, super alloys and/or aluminum alloys.
