Counterblow forging hammer Beche - 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. |
| Closed-die forging | The workpiece is deformed inside a die cavity that restricts metal flow, forcing it to fill the exact shape of the tool. Under high pressure, the material spreads into every recess and detail of the die, producing a part with precise geometry. This method provides high accuracy and repeatability, making it the standard for series and mass production of complex forgings. |
| Counterblow forging | A forging process in which two rams move simultaneously toward each other, compressing the workpiece from both sides. The counter-movement compensates for impact forces, keeping the load on the equipment foundation minimal even at high impact energy. The metal deforms symmetrically and evenly fills the die cavities. This method is especially effective in the production of large forgings where a powerful blow and precise die closure are required. |
| Drop forging | A method of hot closed-die forging in which the workpiece is deformed by the energy of a falling ram. Under the impact, the metal fills the die cavity, reproducing its geometry and taking the shape of the finished part. The process is characterized by high productivity and repeatability, making it in demand in series and mass production. |
