Roll Forming Machine Technology Parameters
Roll forming is a process that which bends metal strips or sheets into predetermined shapes. As the metal is passed through a series of paired rolls, the shape or profile of the metal is changed and forming is accomplished. Roll forming is used to create a variety of shapes, including open channels, box-shaped parts, and complex curves.
The roll forming machine is composed of several parts, including a mechanical unwinder system, a roll form stand, a guide system, and a run out table. The unwinder feeds the metal strip under rollers. Adjustable roll positions allow for bending the metal into the desired shape. The run out table guides the formed metal strip off the roll form stand and into a stacker or collection bin.
When selecting a roll forming machine, several key elements should be considered: material selection, roll design, roll adjustment, guide system, and run out table. Each of these elements performs an individual function, and all must be optimized for the best results. Material selection should be carefully chosen, as not all metals can be successfully shaped with the same parameters. Roll design is the profile of the roller, determining the shape or contour of the finished product. Adjustment of the rollers is required for changing the contour or thickness of a part, and proper adjustment provides consistency from start to finish. Guide systems ensure that the metal strip follows the correct path around the rollers, and are adjustable for different parts. The run out table design is also important in controlling the finish of the parts and preventing buckling or distortions.
When selecting a roll forming machine and its associated technology, careful attention should be paid to the details of each element. Knowing the technology parameters and requirements for individual applications and projects can help in making the best choice and provide a quality end product.
For any rolls forming application, there are several required technology parameters that must be taken into consideration. The type and gauge of the metal being formed is the most important factor when selecting the appropriate roll form machine. The material thickness will determine the number of roll stands, drive power requirements, as well as total length of the roll form line.
The roll form stand is the heart of the roll form line and its design should be tailored for the desired part. All parts should be carefully planned, including entry guide and side guides. The guide system should be designed to precisely control the part profile, and all components should be made from wear resistant materials to ensure long life and consistent quality.
The run out table design is critical for ensuring an even surface finish on all parts. This should include smooth transitions, reduced noise levels, and precision tracking. If a dust and fume collection system is needed, the design should be integrated into the run out table for the best results.
For best results, it is important to select the right roll form machine and technology parameters for the desired application. Knowledge of the technology parameters and requirements for individual projects will help in making the best choice, resulting in higher quality parts and greater performance.
