[0002] Forging equipment refers to mechanical equipment used for forming and separation in forging processing. Forging equipment includes forging hammers, mechanical presses, hydraulic presses, screw presses and flat forging machines for forming, as well as auxiliary equipment such as uncoilers, straighteners, shears, forging operators, etc.

[0003] Forging is the collective name for forging and stamping. It is a forming processing method that uses the hammer, anvil, punch or die of a forging machine to apply pressure to the blank to cause plastic deformation, thereby obtaining a part of the desired shape and size. Forging can be divided into hot forging, cold forging, warm forging and isothermal forging according to the deformation temperature. Cold forging is forging performed at a temperature below the metal recrystallization temperature. Usually, cold forging refers specifically to forging at room temperature. The workpiece formed by cold forging at room temperature has high shape and size accuracy, a smooth surface, fewer processing steps, and is convenient for automated production.

[0004] In the process of cold forging and stamping of plates, manual feeding or feeding with a conveyor roller with a clamp is generally adopted.
