First of all, on the technical analysis of the stamping parts, the overall structure of the stamping die design, drawing the assembly drawing. Stamping is installed in the use of stamping equipment (mainly Press) on the mold to exert pressure on the material, to produce plastic deformation or separation, to obtain the necessary parts (monly known as stamping or punching.) a pressure processing method. Stamping is usually at room temperature cold deformation processing of materials, and mainly used to process sheet metal parts as required, also called cold stamping or sheet metal stamping. Stamping is one of the main methods of pressure processing or plastic materials processing, belonging to the technology of material forming Engineering Keywords: stamping convex die mold punch and die. 目錄 前 言 ....................................................................................................................................................................... 1 第一章 V 型件的工藝分析 ......................................................................................................................... 2 第二章 零件的工藝性分析 ....................................................................................................................... 2 第一節(jié) 尺寸的計(jì)算 .............................................................................................. 3 第二節(jié) 沖裁件的精度與粗糙度 .......................................................................... 3 第三章 沖壓模具總體結(jié)構(gòu)設(shè)計(jì) ............................................................................................................. 4 第一節(jié) 模具類型 .................................................................................................. 4 第二節(jié) 導(dǎo)向與定位方式 ...................................................................................... 4 第三節(jié) 卸料與出件方式 ...................................................................................... 4 第四節(jié) 模架類型及精 度 ...................................................................................... 5 第四章 沖壓模具工藝與設(shè)計(jì)計(jì)算 ....................................................................................................... 5 第一節(jié) 排樣設(shè)計(jì)與計(jì)算 ...................................................................................... 5 第五節(jié) 壓力機(jī)的初選 .......................................................................................... 6 第六章 模具壓力中心的確定 .................................................................................................................. 7 第九章 主要零部件的設(shè)計(jì) ....................................................................................................................... 9 第一節(jié) 工作零件的設(shè)計(jì)與計(jì)算 .......................................................................... 9 第二節(jié) 橡膠的選用 ............
