C41
Self-contained pneumatic hammer requiring no external compressed-air supply — cast iron or cast steel construction, self-priming oil pump lubrication, and over 30 years of documented service in workshops worldwide.
Overview
The Anyang pneumatic forging hammer ranges from 150 kg to 2000 kg and is widely used in industrial open die forging.
The C41 series serves general open die forging applications including drawing-out, upsetting, punching, chiseling, forging welding, bending and twisting, plus open-type close forging with bolster dies.
The hammer body uses cast steel or high-quality cast iron, making it exceptionally sturdy, capable of withstanding significant impact loads and boasting an exceptionally long service life: many units in established forging shops have operated for 30–40 years and more.

Features
These are self-contained pneumatic power hammers requiring no external air supply or high-pressure hoses. Operators can forge heavy stock and immediately switch to thin light stock with no adjustments, gaining tremendous forging power with precise control.
Internal parts are forged steel and precision machined. There are no internal rubber air hoses to deteriorate over time, and the drive belts are external to the machine for easy adjustment and away from harmful oil.
Cast iron construction provides strength and precise mass placement and prevents warping, unlike steel fabricated alternatives.
The motor drives a flywheel with V belts, and the flywheel is attached to a crankshaft set on large tapered roller bearings in a crankcase filled with grease — good for decades of maintenance-free operation.
The compressor piston creates the air pressure directed into the ram sections: the downstroke forces air upward, the upstroke forces it downward. Two compression rings and steel wipers prevent air leakage.
Two valves, an upper and a lower, operate together. They are precision machined steel with no rubber parts to deteriorate over time.
The ram floats on air inside the hammer. The forging force combines the ram weight, the amount of air pressure and the velocity of the ram, with sealing rings and stuffing box wipers.
The lubrication system has an oil reservoir, a flow control metering valve and a one-way check valve. During the downstroke, vacuum sucks oil into the hammer; the upstroke closes the check valve. Oil is not only a lubricant, it is also part of the sealing system.
Easy operation via hand lever or foot pedal, controlling idle run, top setting, pressing down, single blow and series blows as desired.
