笔者推荐的用小冲头自身导向的结构,即在这种结构中不再增加其它导向零件,而是利用小冲头的加粗部分和卸料板的导向套上的孔保持配合要求。用它来导正卸料板的运动方向并承受卸料板由于偶发因素引起歪斜时的弯曲载荷。由于小冲头的抗弯强度是和它的直径的三次方成正比,所以在小冲头的加粗部分其强度是比冲孔冲头处要加大很多,由于要使小冲头的加粗部分承受外
I recommend the structure of the small punch with its own orientation, that is, in this structure is no longer add other guide parts, but the use of small parts of the bold punch and the discharge plate of the guide sleeve to keep the hole with the requirements. Use it to guide the direction of movement of the discharge plate and to withstand the bending load of the discharge plate due to sporadic causes. Since the bending strength of a small punch is proportional to the cube of its diameter, the strength of the thick portion of the small punch is much greater than that of the punching punch. Since the small punch Rough part of the bear outside
