Function of Forming

With the assistance of the forming machine, steel strips of the specified width, thickness, and material, as required by the process, are rolled into steel pipes of the desired specifications according to the preset forming process parameters. There are two forming methods: upward rolling and downward rolling, and we adopt the upward rolling method. The forming machine we use belongs to the outer-hugging type in terms of its operating principle. Essentially, the principle of the forming machine is the same as that of the leveling machine. Both involve the interaction of three rolls, causing the steel strip to endure a certain bending moment. When the bending moment overcomes the yield strength of the material, plastic deformation occurs, thereby rolling the steel strip into a steel pipe.
