Automatic forging machine Hatebur AMP30 - 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. |
| 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. |
| 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. |
| Upsetting | Upsetting relies on the ability of metal to flow plastically under compression. When the workpiece is compressed from the end, the material moves outward, increasing the cross-section exactly where the part design requires. This is how bolt heads, flanges, collars, and stepped transitions are formed. The operation is performed on horizontal forging machines and presses, providing high accuracy and repeatability in the series production of fasteners and rod-type parts. |
| Heading | Forming a head on the end of a rod-type workpiece is a basic operation in the mass production of fasteners. The metal is upset axially and under pressure fills the die cavity, taking the shape of the future head. The process is carried out on cold heading machines and hot heading presses, providing high speed and minimal material consumption. The resulting blanks are used for bolts, rivets, studs, and other parts with a thickened end. |
| Calibrating | A finishing operation that brings the forging to precise dimensions. The workpiece is placed in a calibration die, where under pressure its surface is leveled and the geometry is brought to the specified tolerances. This process eliminates minor shape distortions left after previous operations. As a result, the part receives stable dimensions and a smooth surface without additional machining. |
| Punching | A hole in a solid workpiece is a task handled by bulk punching. The metal is not drilled out but pushed through: the punch penetrates the workpiece, displacing material sideways and forming a through or blind hole. The operation is performed on presses, keeping the metal structure around the hole intact. Used in the production of bushings, rings, and hollow shafts. |
