Process analysis and structure design of automobile filter
Abstract: With the continuous development of China's industry, the mold industry is also becoming more and more important. Aiming at the auto filter impulse cutting process and the deep drawing process, the analysis of the forming process of three different stamping process (single process, complex processes and continuous processes), identified by a composite model completes falls the material, the drawing and punching process.The auto filter of the cold stamping process, after the auto filter batch production, product quality, parts of the structure and use of the analysis, research, without reducing the service performance as the premise, which is identified for stamping parts, stamping parts processing, and a brief analysis of the blank shape, size, layout, the conference board, the number of drawing, stamping processes in nature, number and sequence determined in accordance with.Has carried on the technological force, the pressure center, the mold work part size and the tolerance calculation, and has designed the mold. Also has a detailed analysis of the mold of the main components (such as punch, a discharging device, drawing punch, plate, punch plate, etc.) design and manufacturing, stamping equipment selection, clearance between punch and die adjustment and establishment of a vital parts of the machining process. Lists the detailed list of parts required for the mold,
and gives a reasonable assembly drawing.By making full use of modern mold manufacturing technology to the traditional mechanical parts for structural improvements, design optimization, process optimization methods can greatly improve the production efficiency, the method of similar products have a certain reference role.
