在复杂的冲压翼子板成型过程中,合理的工艺排布是保证生产合格产品的前提,是降低生产成本的关键(零件报废、返修等),文章主要根据翼子板结构特点进行工艺分析,制定了落料一拉延一修边侧修边冲孔一冲孔侧冲孔侧翻边侧整形一翻边侧翻边整形侧整形工艺方案,同时进行了成型模拟分析,对影响成型质量的坯料尺寸及拉延筋结构进行充分的分析,结果表明,坯料尺寸的合理性和拉延筋力的大小设置对产品成型有着重要的影响。
在複雜的遲壓翼子闆成型過程中,閤理的工藝排佈是保證生產閤格產品的前提,是降低生產成本的關鍵(零件報廢、返脩等),文章主要根據翼子闆結構特點進行工藝分析,製定瞭落料一拉延一脩邊側脩邊遲孔一遲孔側遲孔側翻邊側整形一翻邊側翻邊整形側整形工藝方案,同時進行瞭成型模擬分析,對影響成型質量的坯料呎吋及拉延觔結構進行充分的分析,結果錶明,坯料呎吋的閤理性和拉延觔力的大小設置對產品成型有著重要的影響。

During complex fender stamping forming process, a reasonable process route is the prerequisite to ensure qualified products and reduce production cost(scrap, rework and so on). Based on the fender structure, characteristics process analysis is carried out, formulation of blanking-drawing-trimming side trimming amt punching-punching, side punching, side flanging, side plastic-flanging, side flanging, shaping side shaping teehnology, program. At the same time, h~rming simulation is conducted. Amt a full analysis has been conducted on blank size and draw bead structure, which will affect forming quality. Results show that reasonable blank size, set of drawing force have an important influence on forming products.
