端蓋沖壓成形工藝與模具設(shè)計(jì)
摘 要：本設(shè)計(jì)為一端蓋的沖壓模具設(shè)計(jì),我參考了大量有關(guān)拉深模模具設(shè)計(jì)實(shí)例等方面的資料。拉深是利用拉深模將板料制成各種空心件的一種方法，是沖壓生產(chǎn)中應(yīng)用最主要的工序之一。根據(jù)設(shè)計(jì)零件的尺寸、材料、批量生產(chǎn)等要求，首先分析零件的工藝性，確定沖裁工藝方案及模具結(jié)構(gòu)方案，然后通過(guò)工藝設(shè)計(jì)計(jì)算，確定排樣和裁板，計(jì)算沖壓力和壓力中心，初選壓力機(jī)，計(jì)算凸、凹模刃口尺寸和公差，最后設(shè)計(jì)選用零、部件，對(duì)壓力機(jī)進(jìn)行校核，繪制模具總裝草圖，以及對(duì)模具主要零件的加工工藝規(guī)程進(jìn)行編制。其中在結(jié)構(gòu)設(shè)計(jì)中，主要對(duì)凸模、凹模、凸凹模、定位零件、卸料與出件裝置、模架、沖壓設(shè)備、緊固件等進(jìn)行了設(shè)計(jì)，對(duì)于部分零部件選用的是標(biāo)準(zhǔn)件，就沒(méi)深入設(shè)計(jì)，并且在結(jié)構(gòu)設(shè)計(jì)的同時(shí)，對(duì)部分零部件進(jìn)行了加工工藝分析，最終才完成這篇畢業(yè)設(shè)計(jì)。

BEARING CAP PARTS TAMPING
FORMING THCHNOLOGY AND
DIE DESIGN
ABSTRACT: The design for a plate of bearing cap die design, In this design, I made reference to the large number of Die mold design example. The drawing is a drawing die as a processing method of the sheet metal stamping into a variety of hollow, is the most widely used in the stamping process.According to the size of the design components, materials, mass production, etc., the first part of the process of analysis to determine the blanking process planning and die structure of the program, and then through the process design calculations, determine the nesting and cutting board, calculate the pressure and pressure washed centers, primary presses, computing convex and concave Die Cutting Edge dimensions and tolerances, the final design selection of parts and components, to press for checking, drawing die assembly drawings, as well as Mold processing technology of the main parts to the preparation procedures. In which the structural design, primarily to the punch and die, punch and die, positioning parts, unloading and out of pieces of equipment, mold, pressing equipment, fasteners, etc. has been designed, for the selection of some components are standard parts , there is no in-depth design, and structural design, while some parts for the processing process analysis and ultimately to complete this graduation project.
KEY WORDS: mold ,blanking ,deep drawing ,punch ,die ,punch and die
