What is the roll roll forming machine? 1

       
        Roll cold forming is followed by Dangdang metal strip when the number of hole-type roller, with rotating plate with rollers feed forward while being continuously curved, so that the desired cross-sectional shape of the system member. Visible, roll forming is a continuous curved molding method. Figure 2 is molded in a second case of Figure 1 for different sections of the plate belt rollers. Strip at the entrance rollers began to produce bending deformation, and at the same time moved forward, in the center of the section of the roller 4, the end of the forming of the second pair of rollers in and out the roller, and then enter The third pair of rollers.
       Roll cold forming (Cold Roll Forming) is a plate with a total length of successively pass through a number of different local and gradually bending deformation, the whole cross-sectional shape gradually approaching the finished cross-sectional shape, and ultimately get the full-length plastic working method of uniform cross-section of product . Pass is made of two or more having a certain shape forming roll (also known as roller, roller) outline enclosed, forming rolls may be horizontal or vertical roll roll. Hole is one of the important factors affecting product quality and productivity. Forming rolls mounted on the frame, is responsible for driving the strip along the forming roll by a motor driven by the transmission system, generally only horizontal roller to active roll, vertical roll are often passive roll. Each stand called a molding machine, each frame molding machine is equipped with two or more forming rolls, each unit consists of two or more columns forming a molding machine.
