Abstract


The flanging stamping process , widely used in various industries . With the development of the oil , nuclear and electric power industries , many sealed cylinder parts need Burring as a manifold on a Plate . However , in the present study , the plate flanging process for the rich plate flanging less literature . In actual production , plate flange products exist easily crack mouth uneven thickness defects. Therefore, the plate flanging process comprehensive and in - depth research of great practical significance . Papers completed work and the conclusion of the following aspects : 1 , the application of the full amount of theoretical plate flanging process theoretical analysis gives a calculation Plate turned the thickness of the opening portion of the iterative formula . By comparison with experimental results show that the formula in good agreement with the experimental results . 2 the application Deform3D software flanging process research , analysis of different punch the shape of the plate flange forming takeover . The cylindrical punch spherical punch and taper punch to the workpiece shape after flanging , choose the punch shape to provide a reference for the actual production . 3 the precast slab Burring aperture using Deform3D Software , bump die gap and die radius plate flanging process . Orthogonal experimental method to numerical simulation test arrangements , and the test data are analyzed . Using the method of least squares regression equation of the plate flanging mouth thickness data , thus giving plate flanging mouth thickness optimized mathematical model , the use of mathematical models of plate processing parameters to optimize , and optimize the results were verified . Choice of parameters for the actual production and processing to provide a theoretical basis . This study enrich the content and theory of the sheet metal stamping process plate flanging process , can provide reference for the technical personnel engaged in the work of the sheet metal stamping .
