带六角支承垫板落料冲孔复合模.doc

摘 要 模具是制造业的重要工艺基础，在我国，模具制造属于专用设备制造业。本设计是带六角形支承垫板的落料、冲孔复合模，冲模的结构性能直接反映了冲压技术水平的高低。选用材料时应考虑模具的工作特性，受力情况，冲压件材料性能，冲压件的精度，生产批量以及模具材料的加工工艺性能和工厂现有条件等因素。冲床的选用主要是确定冲床的类型和吨位。 关键词 带六角形支承垫板；复合模；冲压技术；冲床 ABSTRACT The mold is the manufacturing industry important craft foundation, in our country, the mold manufacture belongs to the special purpose equipment manufacturing industry. This design is the shimplate with hexagonal support falls the material, the drawing, the formation superposable die, dies the structure performance has directly reflected the ramming technical level height. Selects when the material should consider the mold the operational factor, the stress situation, the pressing part material performance, the pressing part precision, the production batch as well as mold factors and so on material processing shop characteristics and factory existing condition. The punch press selects mainly is determines the punch press the type and the tonnage.
