图1是铁道部科研所由澳大利亚引进防枕木开裂的组合钉板。工件上的钉爪由冲裁,切口,弯曲三种不同的冷冲压工艺组合完成。经过分析,我们将三种冲压工艺利用一个凸模,冲压一次完成一个钉爪的成型。模具结构如图2,当剪切成符合工件宽度的条料以导板18导料,利用导板上的定位槽作初始定位时,进行工件的第一次冲压成型加工,完成长短钉爪各一排。凸模(图3)按照压型、切口、弯曲的先后顺序完成钉爪成
Figure 1 is the Ministry of Railways Research Institute from Australia to introduce anti-sleeper crack combination nail plate. The claws on the workpiece by blanking, incision, bending three different combinations of cold stamping process to complete. After analysis, we will use a stamping process of three punch, stamping completed a nail forming. Die structure shown in Figure 2, when cut in line with the width of the workpiece to guide the guide plate 18, the use of the positioning groove on the guide plate for the initial positioning of the workpiece for the first stamping process to complete the length of the nail each row . Punches (Figure 3) in accordance with the type, incision, bending the nail nail into the completion
