Sheet Cold Roll Forming Machine

Sheet cold roll forming is important for further processing. It is a steel frame construction multi-stage roll forming has a surface shape of the molding unit composed of gradual deformation of the billet, resulting in uniform cross-section of products plastic processing methods. So far, the roll forming technology has been significant development. However, the molding process because of its geometry, kinematics, dynamics and materials science and other aspects of the complex nature of roll forming is still a strong empirical engineering.
   Flower roll forming pass design of cold-formed steel design as the core of the roll forming technology plays an important role. Mill load at a certain intensity, the same basic roller track, how to make sheet metal in all passes of the roller flower design uniform deformation is an important objective. It will have a direct impact on the final dimensional accuracy and deformation profile section defects have also affected the subsequent roller design, production costs and processing cycle.
  Using dynamic explicit finite element method simulation of cold roll forming process, in order to determine the reasonableness of roller flower design is a better choice. ANSYS is a versatile and powerful finite element analysis software. Use its secondary development function to achieve through the interface to enter the default parameters of roller spent to build the finite element model of roll forming, and call LSDYAN solver simulation of its analysis of the entire process can be obtained equivalent plastic sheet stress and strain , took roll parameters to judge the reasonableness of the design, the roller spend optimization.
1 Finite element simulation of cold roll forming process metal roofing machine parameters and Cold roll forming process, the plate in turn arranged in the molding direction after the forming roll, the plane gradually bent by the continuous needs of the various sections. Using ANSYS / LSDYNA its forming process by finite element simulation, the input first set of flowers with cold roll roll parameters, a finite element model for analysis. The channel, for example, the simulation, the use of steel as Q235, sheet size of 8mm × 682mm, finished bend radius of 34mm, bending angle is 77.1 °. Taking into account the rebound, the initial roll flower design  and roll forming roll flower . channel roll formingflower roll language parametric modeling of cold process parameters and output sheet plastic stress and strain analysis of the process shown in Figure 2
