••••••>Know More about Matal & Roll Forming Machine
Author:Lousie Smith Ever since the metal age, when man first discovered that metals could be extracted from rocks, melted and cast into various shapes, the art of the extraction and the recasting process has been radically perfected. The need for new and innovative ways, for metal works, is inspired by the world’s need for different metal products. Look around—from the simple screwdriver to the tallest skyscraper—all are products of metal forming. One of the methods of metal forming is roll forming. The skill to form rolls out of metals is a continuous process. A roll forming machine which creates a roll form is basically an aggregate of several sets of rolls. Each set is called a ‘stand’. The sets are consecutively placed. Each set contributes a small change in the desired cross section of the metal. The roll form will be moved through the ‘stands’ of the roll forming machine, and be shaped by the sets of rolls, until the intended cross sectional pattern is achieved. Sheet metal is commonly used to make roll forms and this process is best suited for making forms with long lengths. Newer roll forming machines offer much versatility. A single roll forming machine will shape a sheet metal into only one cross sectional pattern. One feeds the pattern into the machine and the machine then churns out the desired profile by shaping the metal. You have to remember however that the cross sectional profile should be a uniform design with no variations. Each unique design also requires a specific roll tool. One single roll forming machine has a specifically oriented set of ‘stands’ and it can produce only a single profile. It may be unwise, thus, to have only one roll forming machine at your disposal. Roll forming machinery are generally used for industries, typically heavy industries. Industries that make automobiles or those that make locomotive parts need such machines to shape patterns in the metal without being changed. But if you are to produce a new design then it is not possible to reorient the rolls for the purpose—a new machine will have to be brought in. Roll forming as an art has revolutionized the industry of metal works. As the technology advances, so does its complexity. Newer machinery includes the roll forming presses which produces a roll form via extreme pressure. It will not be surprising if we see more innovations in the future.
