Economy. Polk County's economy has been historically based on three primary industries: citrus, cattle, and phosphate mining. The discovery of phosphate rock in the Peace River, near Fort Meade, Florida in 1881, initiated the mining of the world's largest deposit of phosphate rock, known as the Bone Valley Deposit. This deposit, which ...

Utilizing the FEA tool designers can optimize their designs now more than ever to produce the best roll tools in the industry.
During the course of my 25-year-long experience of endless discussions about rolls, roll application and roll failures with customers and fellow colleagues from other roll producers I found my performance often miserable or worse, frequently due to a lack of common understanding of the basic material science of
For each new tooling requirement in a roll form design, take the following five steps
You can successfully roll-form a profile more than one way. In fact, many roll form designers take different approaches to design and development. Also, because the roll forming process has a seeming limitless capacity to produce complex profiles with just as many variables, many roll form designs are one-of-a-kind therefore, theory can go only so far.
After youve finalized the cross-sectional drawing, youll need to determine the part, material, and mill specifications and tolerances, including steel type and grade. At this point, its best to plan for secondary processes, which can limit roll design options.
Probably the most common problem associated with designing roll tooling is predicting how a forming bend will react during the rolling process. When calculating a strip width, using the proper K factor, or bend allowance, should be your main concern. Various factors contribute to the bend allowance, such as material type and yield strength, profile characteristics such as large radii or 180-degree bends, and roll design techniques.
After theoretically were considered restrictions on the design of appropriate passages proceed to the design of new sets of deformation rollers, which are adapted to the existing roll forming machine.

Roll forming is a versatile process that allows design innovation. Setting up a roll forming line requires the expertise of a skilled roll form designer and cooperation between the vendor and manufacturer in developing a successful product. But with the right preparation, the transition can be painless.
The process of roll forming involves passing a flat strip of sheet metal steel, stainless steel or non-ferrous metal mostly wound as a coil in different widths through a sequence of modular pairs of rollers and forming the desired cross-section at room temperature.
Roll forming is used to produce a cylinder or cone in sheet metal or plate. This is accomplished by pinching the material between two rolls, curving upward as it contacts the back forming roll. It is common to find the upper roll fixed in position and it is the lower roll that raises or lowers to set the material pinching function these are ...
thereby give better design of roll forming machines. A FE-model has been build to investigate the roll forming of a U-channel, paper A. The model has been used to investigate the longitudinal peak membrane strain and the deformation length when increased yield strength, paper B. The simulation shows that the peak strain decreases and the
