Schloemann 1200 MT open die forging press - description

Open die hydraulic press Schloemann 1200 MT — 1200 ton (ID:75616) is forging and pressing equipment designed for open-die forging under conditions of open forming without the use of closed dies. The press develops significant force and ensures deep refinement of the metal structure throughout the entire workpiece cross-section. Used in the production of large forgings — shafts, discs, rings, and other critical parts.

Open die forging press Schloemann - technological processes and operations

Forging The process of plastic deformation of metal, in which the workpiece changes shape under the impact of blows or static pressure. During forging, the metal structure is densified, internal inhomogeneities are eliminated, and the mechanical properties of the material are improved. As a result, forged products are distinguished by high strength and reliability when operating under significant loads. Forging is used both for producing finished parts and for preparing workpieces for subsequent stamping.
Hot forging Hot forging is a process of shaping metal under pressure at elevated temperatures. Heating reduces the deformation resistance of the material, allowing it to flow more easily into the die cavity. The process provides high productivity and the ability to form complex shapes. Used for manufacturing forgings from steel and alloys in series and mass production.
Open-die forging Metal is deformed between flat or shaped tools without lateral restriction, allowing free flow in all directions. The workpiece is gradually shaped by repeated blows or press strokes, with the operator controlling its position between each step. This method is used for producing large forgings such as shafts, discs, and rings, where a refined internal structure is essential.
Preforming Preforming prepares the workpiece for the main stamping operation by giving it an approximate shape of the future part. The metal is distributed in the die to facilitate final filling and reduce tool wear. This intermediate step improves accuracy and quality of the finished product.
Piercing Piercing forms a hole in a solid workpiece by driving a tool through the material without removing it. The metal is displaced sideways, creating a through or blind opening while preserving the structure around it. The operation is performed on presses and is used in the production of hollow parts such as bushings, rings, and shafts.
