How to Troubleshoot an Upright Post Roll Forming Machine

Upright post roll forming machine is a complete line of metal sheet metal fabrication equipment that can do more than just bend or shear the material.upright post roll forming machine It can also straighten it, punch for holes, press for hems and other features, as well as forming it into shelving or rack components that are used in storage and logistic industries.

But not all roll forming lines are created equal. Some are set up to do structural and some stick with roof paneling, and others still focus on ultra-thin or wide profiles. It all comes down to the goals of the company and its available machinery.

Some things that factor into a metal sheet’s thickness limit when run through a roll form machine are the width of the strip and its yield strength. A metal that has a higher yield strength can handle more layers of a profile than a lower yield metal.

The number of passes required to produce a particular component also factors into a roll forming line’s capability. If you’re working with a tall, narrow part that requires many bends, the amount of forming stations you need will increase.

Other things that can influence a roll forming machine’s capabilities are the complexity of the cross-section and the amount of bend angles in the part’s profile. The more dramatic the bend angle is, the more forming stations you’ll need to accommodate it.

It’s important to remember that any troubleshooting effort needs to consider all possible causes of a problem. That means evaluating the entire process chain from the mill to the shop floor, including the quality of the material used and best practices for handling it in upstream processes.

For example, if you’re running a high-quality steel that is properly sized for your line but experiencing problems like center buckle or oil canning, the problem may stem from upstream process issues such as slitting the material to make it narrower. In those cases, the correct solution is to reduce the slit width or work with a different material supplier.

Another common cause of symptoms is poor machine maintenance. Incorrect setup of the machine, improper lubrication of the rollers and shear dies, and misalignment of the upper and lower shafts are all examples of common problems that can occur. To minimize these problems, it’s important that your setup sheets are clearly labeled and that the machine face alignment spacers (the ones closest to the stand) are clean and positioned correctly. It’s also essential that you reposition the shear dies when you switch to a new profile to maintain a consistent cut length.
