3 AYANK FORGING CNC hydraulic forging hammer Core Definition and Application Scenarios Overview

The AYANK FORGING C92KA series CNC fully hydraulic die forging hammer adopts a spool valve structure. Its core advantage lies in the digital precision control of impact energy and impact processes, featuring high forging precision, fast impact frequency, high production efficiency, compact mechanical structure, and a stable and reliable hydraulic system. It is suitable for forging thin-walled parts, complex-shaped parts that are difficult to fill mold cavities, thin-ribbed parts, and forgings with strict tolerance requirements. It is widely used in high-volume, multi-variety production across industries such as automotive, motorcycles, and engineering machinery, while also being adaptable for precision forging of high-density complex-shaped parts in the aerospace industry. It serves as the core forging equipment in automated precision forging production lines.

4 Hydraulic Principle of AYANK FORGING CNC hydraulic forging hammer

4.1 Basic Principle

The motor-pump-accumulator transmission mode is adopted. The lower chamber of the oil cylinder is always connected to the accumulator (in a constant pressure state), and the control system performs single-chamber control on the upper chamber. After the upper chamber inlet valve (striking valve) opens, high-pressure oil from the pump and accumulator, along with high-pressure oil introduced from the lower chamber via the differential circuit, jointly enters the upper chamber, enabling the hammer head to accelerate downward for striking. Once the upper chamber is depressurized, the hammer head immediately retracts rapidly. Precise control of the striking energy is achieved by adjusting the closing time of the striking valve.

4.2 Key Operational Process

• Hammer Lifting State: After the main oil pump starts, it delivers oil to the accumulator, driving the hammer head to lift. The lower chamber of the main oil cylinder is always connected to the accumulator, keeping the hammer head at the upper limit (hammer lifting state).
• Striking State: By controlling the closing time of the striking valve, the striking energy is adjusted. Oil from the lower chamber returns to the upper chamber, and together with high-pressure oil from the pump and accumulator, completes the strike. Multiple overlapping strikes can be achieved (if one strike is insufficient, multiple strikes can be performed).
• Hammer Hovering State: The pressure sensor controls the unloading valve to open, allowing the pump to operate under no load. The accumulator maintains pressure, keeping the hammer head in a safe upper position. The system oil temperature does not rise, achieving energy and electricity savings.

4.3 Core Advantages of the Hydraulic System

Main Striking Valve: Utilizes a spool valve structure with high directional sensitivity and good sealing. It features top-mounted integrated assembly with no pipeline connections, reducing the risk of oil leakage and enhancing system reliability.
• Overall Design: The hydraulic system has a high degree of integration, with a reasonable oil circuit layout and no redundant pipelines. It exhibits strong contamination resistance, stable operation, and convenient maintenance.
