This chart is based on punching mild steel with a 65, 000 lb. shear strength.
All information in this chart should be verified before applying it to your work particularly when using combinations that approach the machine’s maximum tonnage capacity.
Standard Workstations & Features
An Ironworker is a class of machines that can shear, notch, and punch holes in steel plate. The name is now used to refer an entire class of machines. If there ever was a brand name, it's become a genericized trademark.
Ironworkers generate force using mechanical advantage or hydraulic systems. Modern systems use hydraulic rams powered by a heavy AC 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. The Amada Marvel Spartan Series Ironworkers are rated according to the force they can generate in tons; ratings usually start at 60 tons and go as high as 192 tons.
A typical ironworker from Amada Marvel will have:
The double acting punch cylinder is machined and faced to assure proper alignment of the cylinder shaft under maximum load. Cylinder stroke length is adjustable both top and bottom with two easily set limit switches. The see-through stripper provides full view of punch for ease of alignment and operation. The stripper is also adjustable for varying thickness of material.
The various machines punch from 1/8" to 2" in diameter. Punching from 2-1/16" to 4" is achievable with usage of the oversize attachment feature. Punches and dies are easily interchangeable. Both round and shaped tools can be used in the machine.
BAR SHEARING STATION
The round and square bar station allows for shearing various sizes. T-bar and channel shear blades are also available for this station
With the bar shearing feature, rounds and squares can be cut from 1/8" to 2-1/8" (Larger sized holes are available on larger machines only). By changing the blades you can also cut T-bars, H-beams, and channel iron.
FLAT BAR SHEAR
The flat bar shear station has a cast iron support table with guides for accurate positioning and has scribe marks at 90 and 45 degrees for miter cuts. With the adjustable holddown and an upper blade with only a 3 degree rake angle, deformation is held to a minimum. The lower blade has four useable sides. A special feature of the flat bar shear is its variable degree miter-cutting on the bottom leg of the angle iron
Complete daily flat bar shearing with flat and precise results, complimented by the unique anti-distortion blade..
The angle shear allows for both straight and miter cuts of varying sizes of angle material without a drop-out slug. The two wear guides assure the squareness of every cut, while the adjustable holdown keeps distortion to a minimum.
The angle shearing feature allows the option to cut angle iron at 90 degrees, and smaller angle iron at 45 degrees. This feature can be done with both the top and bottom leg.
The notcher is ideal for notching on either flat bars or angles. The gauging table has adjustable stops for precise positioning and the safety guard is electrically interlocked for maximum safety and visibility.
Notching needs are met with a rectangular notching tool, standard on each machine. Marvel can provide special notching tools for a variety of desired applications.
