This opens or deforms the trailing ends of the part. ![]() When the roll formed part is cut, some residual stresses that were created during the process are released. Determining the best spot to make a cut is important because the end product will be different depending on where the cut takes place.Įither way, fabricators must account for flare and determine how forming affects it. The sheet metal can be cut at a specific point on a roll forming line. Punching it after it’s formed may not always be possible or could be more costly. ![]() A machine with more forming points also takes up more space on the shop floor.Ī roll forming line can form, punch, and cut a variety of metals in a range of gauges for use in many industries, including construction. It’s important to determine if the metal should be punched before or after it’s formed. Increasing the bend progression too slowly results in the need for extra dies or forming points at a higher cost. Increasing the bend progression too fast can damage the material and make it challenging to produce a finished product within tolerances. Ultimately, as the progression of the desired bend or fold increases, more wheels or dies are required to make it happen. ![]() The forming is completed by tool steel rolls as they roll over the work metal. Each roll changes the shape of the sheet metal successively as it advances on the line.
