液化石油气罐护罩两側把手,原先需用两套模具冲压三次才能成型。现改为一套模具一次冲压成型,提高了生产效率,保证了产品质量。模具结构见图1,成品件见图2。工作原理图1所示模具能在一次行程中,将筒状半成品护罩的把手处垂直 Liquefied petroleum gas tank shield handles on both sides, the original need to use two sets of mold stamping three times to shape. Now a stamping die into a set, improve production efficiency and ensure product quality. Die structure shown in Figure 1, the finished product shown in Figure 2. Working principle Figure 1 shows the mold can be a stroke, the cylindrical semi-finished guard handle vertical
