In drop forging, hammers are used to forge the metal between two dies. The anvil and the hammer are connected by the first half of the die. The material is put into the lower die, and the higher die is used to hammer the material until the hot metal flows into all of the derections and fills the cavity of the lower die. Prior to the invention of presses, the first industrial procedure for ᴄʟᴏsᴇd die forging was drop forging.
Hammers distort the material by applying impact strain. A series of several continuous blows on the same die propel the ram into the workpiece at a speed of more than 1/1,5 m/sec; in contrast, forging presses only require 1 to 2 strokes. Hammers can be identified by the amount of energy they create with each stroke, which is expressed in J, kJ, and kg-m. A 250 kJ (25 000 kgm) hammer delivers an energy comparable to the fall of a mass of 25 metric tons from a height of one meter with each strike.
Depending on the ram movement’s drive, hammers are categorized as single effect (drop forging), double effect, and counterblow hammers. Due to their high adaptability and versatility, these tools are primarily used in small and medium series production. To create automotive components in large series, such as connecting rods for cars and trucks, automatic hammers have been designed. Hammers are most suited for the forging of heavy parts made of steel, nickel-based alloys, or titanium as well as thin components (such con rods and airfoils).
Setforge has top-notch equipment and tools with the greatest dies. For steel, stainless steel, nickel-based alloys, and titanium components in all business categories, we utilize single, double effect, and counterblow hammers.
