冲击气缸是一种新型的气动执行元件——动力装置,它能把压缩空气的能量转化为活塞高速运动的动能。利用此能量可完成冲孔、型材和棒料的高速精密剪切、板件的铆接、合件的压套、零件的打印、弯曲成型和脆性材料的破碎等多种冲压作业。与同尺寸普通气缸比较,冲击能量大100倍以上。仲击气缸的缺点是冲击效率较低,大直径的冲击气缸只适宜单打作业,小直径的冲击气缸可搞成自动气控回路,工作频率可达每分钟50～80次。结构与技术参数图1是90型冲击气缸总成图。其中固定密封采用耐油橡胶O型密封圈,运动密封采用耐油橡胶Y型密封圈。它与普通气缸的区别在于增加了一个贮能缸和带泄流塞与有流线型喷口之中盖。下盖有四个孔道,其中一个孔道与两位四通气控换向阀相联,另三个孔道与快速排气阀相通。
Impact cylinder is a new type of pneumatic actuator - power plant, which can convert compressed air energy into high-speed kinetic energy of the piston. This energy enables punching, high-speed precision cutting of profiles and bars, riveting of plates, press fit of parts, printing of parts, bending and crushing of brittle materials. Compared with the same size ordinary cylinder, impact energy more than 100 times. The shortcoming of the mid-air cylinder is that the impact efficiency is lower. The large-diameter air cylinder is only suitable for single-shot operation. The small diameter air cylinder can be made into an automatic air control circuit. The working frequency can reach 50 to 80 times per minute. Structure and technical parameters Figure 1 is a 90-type impact cylinder assembly diagram. One fixed oil seal with O-ring, the use of oil-sealed Y-seal movement. It is different from the normal cylinder is the addition of an energy storage cylinder and a drain plug with a streamlined nozzle cover. The lower cover has four holes, one of the holes is connected with two four-way air control valves, and the other three holes are communicated with the quick exhaust valve.
