This design using the basic knowledge of bending forming technology and die design, analyzes the performance requirements of the plate, ready for the selection of mold types;Then calculated the bending force of bending parts, easy to choose press tonnage and determine the press type;In the final analysis the characteristics of bending parts, mold design parameters, key points of design and selection of ejection device.This design USES the figure of eight pendulum block type compound die.Composite mould has high production efficiency, high precision parts, especially suitable for mass production and high precision.Forming principle can be divided into two stages: first, the combination of convex and concave die shape U;Die to continue downward, forced the pendulum swinging movements, u-shaped bent by forming again, finally forming parts, this kind of agency action is flexible and reliable, convenient design, very suitable for use in the vice mould.Keywords: bending punch die set piece目 錄1 緒 論11.1國內(nèi)模具的現(xiàn)狀和發(fā)展趨勢11.1.1國內(nèi)模具的現(xiàn)狀11.1.2國內(nèi)模具的發(fā)展趨勢11.2國外模具的現(xiàn)狀和發(fā)展趨勢21.3 支架模具設(shè)計(jì)與制造方面21.3.1 支架模具設(shè)計(jì)的設(shè)計(jì)思路21.3.2支架模具設(shè)計(jì)的進(jìn)度32 彎曲件工藝性分析及方案的確定42.1彎曲件工藝性分析42.2工藝方案的確定42.3彎曲件工藝方案分析73、主要設(shè)計(jì)計(jì)算83.1主要設(shè)計(jì)計(jì)算83.1.1彎曲件毛坯坯料尺寸計(jì)算83.1.2 彎曲應(yīng)力的計(jì)算93.1.3 圧料力計(jì)算93.1.4 壓力機(jī)公稱壓力的確定93.2彎曲模工作部分尺寸的設(shè)計(jì)103.2.1凸模圓角半徑設(shè)計(jì)103.2.2 凹模圓角半徑103.2.4 凸、凹模間隙計(jì)算113.3 U形彎曲凹凸模橫向尺寸的設(shè)計(jì)123.4 彈簧的選用133.4.1每個(gè)彈簧力計(jì)算133.4.2彈簧預(yù)壓縮量143.4.3彈簧校核144 模具類型的選擇154.1 模具結(jié)構(gòu)選擇154.2定位方式的選擇164.3出件方式的設(shè)計(jì)165 主要零件的設(shè)計(jì)175.1工件零部件的結(jié)構(gòu)設(shè)計(jì)175.1.1凸模的結(jié)構(gòu)草圖如下圖所示：175.1.2凸模主要尺寸的計(jì)算175.2凹模的結(jié)構(gòu)設(shè)計(jì)195.2.1凹模主要尺寸的設(shè)計(jì)195.3.2擺塊的主要尺寸設(shè)計(jì)205.4定位零件的設(shè)計(jì)215.4.1限位釘?shù)脑O(shè)計(jì)215.5定位塊的設(shè)計(jì)225.6彈頂部件的設(shè)計(jì)235.6.1墊片的設(shè)計(jì)235.6.2導(dǎo)板的設(shè)計(jì)236 壓力機(jī)的參數(shù)與比較247 模具零件的加工工藝257.1凸模的加工工藝過程257.2凹模的加工工藝過程258 模具的裝配279 模具試沖28設(shè)計(jì)小結(jié)29致謝30參考文獻(xiàn)31III
