Ironworker is a class of machines that can shear, notch, and punch holes in steel plate. There may have been a brand name called Ironworker. The name is now used to refer to the whole class of machines (made by at least a dozen brands, such as Piranha, GEKA, Pedinghaus, etc.). If there ever was a brand name, it has now become a genericized trademark. Ironworkers generate force using mechanical advantage or hydraulic systems.
Modern systems use hydraulic rams powered by a heavy alternating current electric motor. High strength carbon steel blades and dies of various shapes are used to work the metal. The machine itself is made of very heavy steel to handle the enormous force that can be generated during use. Ironworkers are rated according to the force they can generate in tons; ratings usually start at 20 tons and go as high as 150 tons.
Ironworkers are tools just like hammers and wrenches but they provide many more safety hazards that must be addressed and thoroughly thought out before they are purchased. Most of them have at least 4 stations that require boundaries around them to safely produce parts. They can shear flat plate, angle iron, round and square bar stock as well as punch plates, angles, I-beam and channel iron. Some have a station for notching and forming of different materials. The area around each station should be at least 20 feet since that is the common stock length of most materials used on ironworkers.
Operations which can be performed include:
Due to the reduction in the amount of man hours and effort needed to cut or punch steel sections, an ironworker is often an integral part of commercial manufacturing facilities and fabrication shops. They are easily re-tooled for various operations and can be operated by one person.
