軸蓋沖壓模具設(shè)計(jì)
摘要:隨著科學(xué)技術(shù)的發(fā)展需要,模具已成為現(xiàn)代化不可缺少的工藝裝備。而沖壓模具主要用于生產(chǎn)具有良好沖壓成形性能的金屬和非金屬制品,通過(guò)對(duì)模具的設(shè)計(jì)使零件沖壓成型并達(dá)到生產(chǎn)使用要求。
本論文是應(yīng)用本專業(yè)所學(xué)的理論知識(shí)和生產(chǎn)實(shí)習(xí)知識(shí)相結(jié)合的一次沖壓模具設(shè)計(jì)。通過(guò)對(duì)軸蓋沖壓件的沖壓工藝性綜合分析,毛胚直徑,修邊余量,是否需要壓邊圈,拉伸次數(shù)及翻遍前預(yù)沖孔尺寸的參數(shù)計(jì)算從而確定了沖壓件的最佳工藝方案;通過(guò)計(jì)算板料的利用率,詳細(xì)分析板料排樣設(shè)計(jì)的合理性;通過(guò)對(duì)沖裁件的沖裁方式的分析及沖裁過(guò)程中所需力的計(jì)算,選用了模架總體結(jié)構(gòu)和沖壓設(shè)備,并對(duì)模具強(qiáng)度要求作了說(shuō)明。本論文主要設(shè)計(jì)了凸凹模刃口尺寸及加工工藝,凸凹模的固定方式,導(dǎo)料板,打料板,推出機(jī)構(gòu),模柄及固定方式,模具閉合高度,彈性元件,模具安裝定位及分型面的設(shè)計(jì)。

The Mold Design of Shaft End Covers Punching
Abstract: With the development of science and technology, mould has become the indispensable equipment modernization. Mainly used for production and stamping mould has good performance of stamping metallic and non-metallic products, mould design by stamping parts, and achieve production requirements.
This paper is the application of this theory knowledge and professional knowledge of production practice combining a stamping mould design. Based on axial cover stamping technology, comprehensive analysis, trimming surplus embryos diameter, whether to need blank-holder, tensile rate and gets rummaged through before the parameters are calculated to punch size determined the optimum scheme stamping, Through calculation, a detailed analysis of sheet metal utilization layout design reasonable. Through the hedge cutting blanking mode analysis and process of cutting force calculation for the formwork, general structure and stamping mould device, and the required strength. This thesis mainly designed for intensive processing technology, and the size of the intensive fixed way, conducting plate, plate material, institutions, and handle and fixed way, mold closing height, elastic components, tooling and positioning of design.
Key words: multiple spaces into national level;technological analysis;mold structure.
