挡料装置是材料沿送进方向的定位零件，在单工序落料模或复合模设计中，挡料装置的使用相当广泛，它能够确保人工送料得到准确的进给量，从而保证零件能够保持完整的轮廓或具有一定的搭边。在实际设计过程中，往往因冲压件的形状和排样的不同，以及挡料空间的限制，挡料装置的 The stop device is a positioning component along the feeding direction. In the single-process blanking or compound die design, the stop device is widely used to ensure that the manual feed can be accurately fed to ensure that the part can be kept Complete outline or have a certain edge. In the actual design process, often due to the stamping parts of the shape and layout of the different, as well as the limitations of the material space, blocking device
