　　Angle Chi embossing machine is widely used in many applications. However, the molding process is a very complex process, and many problems have not been solved, and are usually found during manufacturing debugging. Taking wide section sheet forming as an example, if the design is not reasonable, there will be deformation defects such as side wave, pocket wave, longitudinal bending, corner wrinkle, crack and skew in the debugging process. If the machining roller is redesigned after the failure of the Angle tile machine, it will inevitably lead to a huge waste of human and material resources. By understanding the mechanism of these defects, we can try to avoid these defects during the design process, and make reasonable improvements to the character after the defects occur, in order to reduce or reduce these defects and achieve the intended goals of the character design.

　　Analyze and solve the problem of Angle embossing machine:

　　1. The influence of the front pass and the back pass on the bag wave is greater than that of the middle pass, especially the back pass. Bag wave generation can be achieved by using multiple forming paths. The size of the edge width of the section affects the bag wave, and the bag wave is easier to appear in thin plate than in thick plate. By applying tension to the plate, the still wave can be moderated.

　　2, each pass has the possibility of side waves, and the previous pass has a great influence on the appearance of side waves. Thin plates are more prone to side waves than thick plates, and wide and narrow plates are more prone to side waves. To reduce or remove the wave of the edge, note that in the early stages of design, the side width of the section is too large and the design is made with reference to the ratio of the side width of the section to the thickness of the plate being close to or less than 40. The bending Angle can be specified by reference to the empirical formula. If side waves are encountered during rolling, partial tool paths can be added as needed to reduce or remove them.

　　3, the following road sequence has a great impact on the longitudinal bending, in the same section and roll configuration, thick plate is easier to form longitudinal bending than thin plate. To reduce or remove longitudinal bending, design the correct distribution of deformation. In addition, please do not deform the back too much. The vertical bending can be reduced by bending forward, increasing the line, using a straightener, changing the frame spacing, using rolling and adjusting the rolling spacing.
