Open Die Forging Hydropress Alloy Steel Tube Plate

Open Die Forging Hydropress Alloy Steel Tube Plate

1. There are a wide variety of open die hot forging processes; including slab, shaft, mandrel, ring and hollow forging.
2. Forgings vary in size, ranging from 0.5 kg up to 300 tonne shaft forgings.
3. Mainly performed on gravity drop, double-acting and counterblow hammers. A forging hammer is a mechanical version of the blacksmith’s hammer and anvil. It consists of a heavy mass or tup, which is allowed to fall or is driven down onto the workpiece, and an anvil on which the hot workpiece is placed. They are very versatile and relatively quick in action. Deformation is achieved by a rapid succession of hammer blows. Energy rating of hammers range from 500 to 40,000 kg-m.
4. Hydraulic presses are used for large forgings such as large turbine shafts. They are slow in operation and the workpiece often requires to be reheated several times.
5. In most cases shaping of the component relies on the skill of the forgemaster. Larger workpieces are supported by chain slings or semi-automatic manipulators.
