Engineering Dynamic manufacturing techniques, innovative products and continuous process improvements let Patriot Forge Co Open-die shape capability is indeed wide in latitude.
In addition to round, square, rectangular, hexagonal bars and other basic shapes, open-die processes can produce:. Not unlike successive forging operations in a sequence of dies, multiple open-die forging operations can be combined to produce the required shape. At the same time, these forging methods can be tailored to attain the proper amount of total deformation and optimum grain-flow structure, thereby maximizing property enhancement and ultimate performance for a particular application.
Forging an integral gear blank and hub, for example, may entail multiple drawing or solid forging operations, then upsetting. Similarly, blanks for rings may be prepared by upsetting an ingot, then piercing the center, prior to forging the ring. Seamless rolled ring forging is typically performed by punching a hole in a thick, round piece of metal creating a donut shape , and then rolling and squeezing or in some cases, pounding the donut into a thin ring.
Ring diameters can be anywhere from a few inches to 30 feet. Performance-wise, there is no equal for forged, circular-cross-section rings used in energy generation, mining, aerospace, off-highway equipment and other critical applications. Seamless ring configurations can be flat like a washer , or feature higher vertical walls approximating a hollow cylindrical section.
Heights of rolled rings range from less than an inch up to more than 9 ft. In fact, seamless tubes up to in. Even though basic shapes with rectangular cross-sections are the norm, rings featuring complex, functional cross- sections can be forged to meet virtually any design requirements.
A key advantage to contoured rings is a significant reduction in machining operations. Not surprisingly, custom-contoured rings can result in cost-saving part consolidations.
Compared to flat-faced seamless rolled rings, maximum dimensions face heights and O. High tangential strength and ductility make forged rings well-suited for torque- and pressure-resistant components, such as gears, engine bearings for aircraft, wheel bearings, couplings, rotor spacers, sealed discs and cases, flanges, pressure vessels and valve bodies.
Materials include not only carbon and alloy steels, but also non-ferrous alloys of aluminum, copper and titanium, as well as nickel-base alloys. Home Types of Forging Processes. Types of Forging Processes There are basically three methods or processes to make a forged part. Still Graphic Animated Sequence Video Process Capabilities Commonly referred to as closed-die forging, impression-die forging of steel, aluminum, titanium and other alloys can produce an almost limitless variety of 3-D shapes that range in weight from mere ounces up to more than 25 tons.
Back To Top Cold Forging Most forging is done as hot work, at temperatures up to degrees F, however, a variation of impression die forging is cold forging. Process Capabilities Cold forging encompasses many processes bending, cold drawing, cold heading, coining, extrusion, punching, thread rolling and more to yield a diverse range of part shapes.
A casting has neither grain flow nor directional strength and the casting process cannot prevent formation of certain metallurgical defects. Pre-working forge stock produces a grain flow oriented in directions requiring maximum strength. Dendritic structures, alloy segregations, and similar imperfections are also refined in forging.
Forgings are consistently more reliable and often less costly over time compared to castings. Casting defects occur in a variety of forms. Because hot working refines grain patterns and imparts high strength, ductility, and resistance to each forged piece they are also more durable.
Also, they are manufactured without the added costs for tighter process controls and inspection that are required for castings. Forgings also offer better response to heat treatment. Castings require close control of melting and cooling processes because alloy segregation may occur.
This results in a non-uniform heat treatment response that can affect the straightness of finished parts. Forgings respond more predictably to heat treatment and offer better dimensional stability. Production of forgings allows for flexible, cost-effective adaption to market demand. Some castings, such as special performance castings, require expensive materials and process controls, and longer lead times.
Open-die and ring rolling are examples of forging processes that adapt to various production run lengths and enable shortened lead times. Forgings offer production economies and material savings. Welded fabrications are more costly in high volume production runs. In fact, fabricated parts are a traditional source of forging conversions as production volume increases.
Initial tooling costs for forging can be absorbed by production volume and material savings. Welded structures are not generally free of porosity.
Any strength benefit gained from welding or fastening standard rolled products can be lost by poor welding or joining practice. The grain orientation achieved in forging makes stronger parts. Forgings also offer cost-effective designs.
A multiple-component welded assembly cannot match the cost-savings gained from a properly designed, one-piece forging. Such part consolidations can result in considerable cost savings. In addition, weldments require costly inspection procedures, especially for highly stressed components. Forgings do not. Forgings offer more consistent, better metallurgical properties. Selective heating and non-uniform cooling that occur in welding can yield undesirable metallurgical properties such as inconsistent grain structure.
When in use, a welded seam may act as a notch that can contribute to part failure.
