１液压缓冲降噪原理冲裁时，冲头一旦接触金属板料，冲裁力开始增加。与此同时，由于机身及其它受力构件的变形而积累了弹性能。当冲头进入板料约一半厚度时，冲裁力达到最大值。板材的突然断裂使冲头突然失荷，机身等积累的弹性能在极短时间内释放出来，将激起机身及各部... A hydraulic buffer noise reduction principle Blanking, punching the metal plate once the contact, the blanking force began to increase. At the same time, due to the deformation of the fuselage and other components of the force accumulated elastic energy. When the punch into the sheet about half the thickness, the maximum blanking force. The sudden rupture of the plate causes the punch to suddenly lose its weight, and the accumulated elasticity such as the fuselage can be released in a very short period of time, which will arouse the fuselage and the ministries ...
