Experimental process analysis:

Remove the side ribs from the outside of the product tube and then bend and shape. Observe whether there is distortion on both ends of the product after molding. If the product is distorted, the side indicates that there is a problem with the current model. In the absence of ribs, the product is symmetrical and should not be distorted during molding. At this point, the simple mode should be repaired to achieve no distortion when there is no rib. Then try again if there is any distortion in the product when there is a reinforcement. If the twisted side indicates that the side ribs will cause distortion of the product during molding, the twisting amount will be compensated when the new mold is opened. If not twisted, this problem is not considered when opening the mold.

Description:

According to the theory of elastic-plasticity, deduces the expression of the relationship between the radius of curvature before and after roll forming and compensates the springback; Then based on the G Clef 3-axis profile bending machine, the coordinate control system for the roll bending motion of the profile was established, and the mathematical model between the roller bending forming radius and the roller feed rate in the 3thre process stages of roll bending, centering, pre-bending, continuous roll bending and unloading was solved. Furthermore, deduces the formulas for calculating the load on each roller and driving power of the driving roller in the molding process.
