The Air Hammer GSH 41 is employed for light and medium?weight forging, such as forging the ends of ornamental scrolls and handrails as well as hot- and cold?forging of ornamental bars. The delicate?forging dies and the dies from series No. 51xx are applied with Air Hammer GSH 41.

Main bars, forged bars, intensively profiled ornamental bars, the ends of ornamental scrolls, front ends of handrails, lamp stands, ornamental leaves and ornaments must be hot-forged with a forging hammer. Four Air Hammers GSH are available for this purpose, differing in forging capacity and blow force.

Characteristics
The Air Hammers GSH are free-form forging machines. All hammers are welded steel constructions. Compression and working cylinders are fully integrated into the machines. Lubrication is done automatically via a central lubricating system. The Hammers GSH are noise-reduced and meet all requirements to human working conditions such as low noise, protection against oily air exhausts and simple operation.

Function
The motor drives a large flywheel via V-Belts As with an internal combustion engine, a connecting rod connects the camshaft-shaped flywheel with the compression piston. The compressed air is fed to the working cylinder via a control-slider and lifts the ram. The control-slider is operated by a treadle, allowing an accurate adjustment of the blowing force.

Installation
The hammers must be set up vibrationless. A static foundation plan is supplied for all hammers. The accessories for mounting, such as shock absorbers, vulkollan plate and stone screws are supplied for extra charge. 

Dies
The hammers must be set up vibrationless. A static foundation plan is supplied for all hammers. The accessories for mounting, such as shock absorbers, vulkollan plate and stone screws are supplied for extra charge.

Easily exchangeable dies are inserted in anvil and ram for forging. A variety of standard dies is available and is permanently extended. Special shapes and untempered dies are supplied on request after clarifying technical details.

Our forging dies are made of high-tensile chromium steel. If the geometric shape allows for it, they can be used for both cold- and hot-forging.

Example for dies for cold-forging:
No. 5116/5216 and No. 5146/5246.

Bars can be evenly cold-forged with dies No. 5106/5206 and No. 5139/5239. If the bars are to be conically-forged, they have to be heated first.

Example for dies that cannot be used for cold-forging:
No. 5128/5228, No. 5129/5229 and No. 5147/5247

The dies are fixed to the anvil resp. ram with a wedge. Wedges with different sizes are available. A wedge-ejector is supplied for removing the wedges.
