Benefits of a Curving Roll Forming Machine

A curving roll forming machine is an apparatus that enables longitudinal bending of panels. It can impose a convex or concave curve, and is equipped with an adjustable hand tooling system. It also enables multiple bending arrangements. The present invention can be used to create various panels, including roof panels.

Another benefit of a curving roll forming machine is that it can reduce your production costs by reducing the number of secondary processes. A pre-cut shear cuts metal before it passes through the forming stations, resulting in a more clean cut to the flat metal. Some models also come equipped with a hydraulic tank, but these are not standard. Adding a hydraulic tank can increase the speed of the machine and automate the shears.

Another benefit of a curving roll forming machine is that it can produce nearly limitless lengths without the need for manual processing. This is a huge advantage for manufacturers looking for a low-cost alternative to stamping, extrusion, and press braking. The process can also produce parts with extremely tight tolerances and a perfect finish.

The process begins with a coil of sheet metal, which can be anywhere from one inch to 30 inches wide. It is important to prepare the coils before the forming process. The following diagram shows the various steps involved in the forming process. Once the process has been completed, the coil is discharged.

The production rate of a roll forming machine depends on the material, bend radius, and number of stations required. For example, a low carbon steel with a fifty times bend radius can be processed at 85 feet per minute if eight stations are used. With twelve stations, it is possible to produce up to 22 inches of steel per minute. However, this production rate is limited by the number of punching applications.

Another feature of a curving roll forming machine is its ability to bend panel sections. The sweep rollers in this machine are configured to match the profile of a panel section and allow for the panel to be bent. It is possible to adjust the sweep rollers and the offset roller pairs so that the curves are concave or convex.

The first tooling raft 12 of a curving roll forming machine includes pinch rollers, sweep rollers, and cantilever rollers. Additional rollers can be fitted to the panel section. In addition, the rafted tooling system allows fabricators to change the tooling without changing the entire machine. The raft is then lifted by an overhead crane or a forklift and replaced by the desired profile. This configuration eliminates the need for manual tooling changes, reducing the chance of errors and ensuring correct gap setting.

The curving roll forming machine utilizes a series of precisely placed rollers to form metal strips into complex shapes. Each roller completes a different step in the process. The rollers are crafted with a flower pattern that identifies the sequential changes made to the metal strip. The flower pattern on the rollers helps create the shape of each roller.
