The support components ramming craft and dies the design Student name : Luo Jian Class: 0781053 Supervisor: Chen Wei Guo Abscract: The mold is the manufacturing industry important craft foundation, the mold manufacture belongs to the special purpose equipment manufacturing industry. The mold technology has gathered the machinery, the electron, chemistry, optics, the material, the computer, the precise monitor and the information network and so on many disciplines, is a comprehensive nature multi-disciplinary systems engineering. The mold technology development tendency mainly is the mold product to larger-scale, preciser, more complex and a more economical direction develops, the mold product technical content unceasingly enhances, the mold manufacture cycle unceasingly reduces, the mold production faces the information, is not having the chart, is fine, the automated direction develops, the mold enterprise to the technical integration, the equipment excellent, is producing approves the brand, the management information, the management internationalization direction develops. This time designs a set to flush spatially, falls the material the mold. After the consult material, first carries on the process study to the components, undergoes the process study and the contrast, uses the punch holes to fall the material working procedure, through the blanking force, pushes computations and so on material strength, ex-denning strength, definite press's model. The analysis is suitable the mold which again to the blanking processing's mold the type choice must design. After obtaining mold type which, will design expresses mold's each work spare part design process. In the instruction booklet first part, mainly narrated the ramming mold's development condition, explained that the ramming mold's importance with this design's significance, is to pressing part's process study, completes the craft plan the determination. The second part, to the components row of specimen map's design, has completed the material use factor computation. Carries on the blanking craft strength again the computation.
