A variety of die-forged chains, hydraulic cylinders, and forgings. The processing equipment for hydraulic cylinder forgings includes forging hammers and hydraulic presses. The forging hammer employs the original method, utilizing forging techniques and external force to alter the shape of metal, i.e., by the tremendous external force exerted by the forging hammer on the metal, causing it to change shape. This method ensures even metal stress on all surfaces of the forged cylinder, making it widely used. However, forging with a hammer requires a high-temperature environment as metal deformation necessitates a change in hardness, which can be cumbersome for metals with high melting points. Consequently, a two-method forging process is often employed, involving the use of a hydraulic press. The hydraulic press alters the shape of the cylinder forging through static pressure generated by liquid, eliminating the need for high temperatures. Hence, many large hydraulic cylinder forgings are forged using hydraulic presses.
