Forging hammers are used in forging to form a metal between two dies. The first half of the matrix is ​​attached to the anvil, and the second part — to the hammer. The material is placed in the bottom head and then clogged with the top until the hot metal flows in all directions, filling the cavity of the matrix. Forging stamping is the first industrial process that was developed for forging in closed dies prior to the introduction of presses.

Hammers use impact load to deform the material. The pusher is pushed into the workpiece at a speed of more than 1 / 1.5 m / s due to the sequence of several continuous blows at the same matrix; on the contrary — forging presses require from 1 to 2 blows. Hammers are characterized by the energy produced for each blow (blow), which is indicated in J, kJ and kg-m. A hammer of 250 kJ (25 000 kgm) produces, at each stroke, the energy equivalent of a weight drop of 25 metric tons from a height of 1 m.

Hammers are divided into a single effect (forging by drop), a double blow and a hammer with a retaliatory strike, depending on the direction of movement of the plunger. These are very flexible and multivalent tools, therefore they are intended mainly for small and medium batch production. However, automatic hammers were developed for the production of automotive parts of a large series, such as connecting rods for engines of passenger cars and trucks. Hammers are particularly suitable for forging thin components (such as rods, airfoils) and heavy parts made from steel, Ni-based or titanium alloys.

Setforge owns excellent equipment and tools, equipped with the best stamps. We use single, double effect and impact hammers, for all business areas, for steel, stainless steel, nickel-based alloys and titanium components.
