Advantages and Forging Applications of the C66Y-875KJ (25-Ton) Fully Hydraulic Open-Die Forging Hammer
The C66Y-875KJ open-die hydraulic forging hammer features a 25-ton falling weight and a rated striking energy of 875 kJ. Paired with a forging manipulator, it performs open-die free forging operations, including drawing out, upsetting, punching, mandrel expanding, and cutting.
Key Advantages of the C66Y-875KJ Open-Die Hydraulic Forging Hammer
Excellent material forgeability, making it ideal for hard-to-deform alloys (a key highlight).
High-speed impact loading enables instantaneous, significant deformation, making it suitable for materials with poor plasticity and narrow deformation temperature windows, such as superalloys and titanium alloys. Repeated impacts break down the coarse as-cast structure of ingots, weld internal porosity, and refine grains—advantages that static-load rapid forging presses struggle to match.
Continuously adjustable impact energy and exceptional process flexibility.
Supports light blows, heavy blows, and rapid-fire sequences with stepless energy adjustment; the hammer head can hover at any position, accommodating various processes such as upsetting, drawing out, and punching.
Fully hydraulic drive ensures rapid response and high-speed repetitive striking capabilities.
Features a servo-hydraulic system for fast return strokes and continuous striking; integrates with manipulators for high forging throughput. Energy storage via accumulators results in lower energy consumption compared to traditional steam or air hammers; eliminates the need for boilers, allows for immediate startup, and offers an eco-friendly, low-pollution operation.
