冲击式气缸是七十年代初英国马通公司生产的一种气动装置。一九七五年曾在《上海机床和英国科学仪器展览会》上展出过,目前,国内已有不少单位进行研制和应用。我厂于一九七八年三月完成了首台研制任务,不久又生产了第二台,并作为小型冲床分别用于六号产品前后机身对接螺栓安装口盖孔及后机身不锈钢导风罩孔的冲切,使用效果较好。以不锈钢导风罩为例,比手工钻孔提高效率4～5倍,比气动杠杆式冲孔机冲孔提高效率1～2倍,且切口周围平整,孔壁光滑,质量好。冲击式气缸与机械冲床相比,具有能量
Impact cylinder is a kind of pneumatic device produced by England Ma Tung Company in the early 1970s. In 1975, he had exhibited at “Shanghai Machine Tool and British Scientific Instruments Exhibition”. At present, quite a few units in China have been developing and applying them. Our factory completed its first development task in March 1978 and soon produced the second one, which was used as a small punch for the body-mounted bolt holes and post-body stainless steel guides Wind cover hole punching, the use of better. Take the stainless steel air guide cover as an example, to improve the efficiency by 4 to 5 times than the manual drilling, and to increase the efficiency by 1 to 2 times than the punching with the pneumatic lever punching machine. The periphery of the incision is smooth, the hole wall is smooth and the quality is good. Impact cylinder with mechanical punch compared with energy
