第一章冲压机械§1.1 根据冲压工艺选定压力机的种类通常,把冲压力随加工行程的变化曲线称为冲压加工压力行程曲线。不同的冲压工艺要求的压力行程曲线的形状也不一样,代表性的形状如图1—1所示。
Chapter stamping machinery §1.1 Pressing process according to the type of press selected In general, the stamping force with the machining curve of the curve known as the stamping process pressure stroke curve. Different stamping process requires pressure stroke curve shape is not the same, the representative shape shown in Figure 1-1.
