Description

Technical Field

[0001] The utility model relates to the field of free forging equipment, in particular to a free forging rotary table. Background Technique

[0002] As is known, the free forging process has requirements for the starting forging temperature and the final forging temperature; especially for the final forging temperature, once this temperature is reached, the forging process must stop, otherwise the workpiece will be cracked and scrapped due to too low temperature. At this time, the workpiece needs to be put into the heating furnace again for heating, and it can be forged again after reaching a certain temperature;

[0003] In the existing technology, there is a problem that it is inconvenient to center and position disc-shaped workpieces of different sizes during forging, which will cause the disc-shaped workpieces to shift on the workbench during forging, and finally lead to the results of the disc-shaped workpieces falling and injuring external personnel, with low safety factor. For this reason, we propose a free forging rotary table. Content of the Utility Model
