岩心卡簧是小口径钻进采取岩、矿心的重要工具之一,消耗量较大.过去采用的一般加工工艺是:下料-车外锥面-插内锥形槽-热处理-精磨-开侧切口.这种工艺因需用插床、磨床等设备,一般野外修配车间难于解决,同时因工件薄,加工时容易出废品,效率低,成本高,给卡簧供应造成一定困难.西安地质学校机械专业的师生遵照毛主席“学校是工厂,工厂也是学校”的教导,坚持走“五·七”道路,主动承担了用
Core retainer is one of the important tools for small diameter drilling to take rock and ore core and consume a lot of energy. The general processing technology adopted in the past is: cutting - outer conical surface - inner conical groove - heat treatment - fine grinding - Open the side of the incision. This technology due to the need to slot machines, grinding machines and other equipment, the general field repair workshop difficult to solve, and because of the workpiece thin, easy to waste out of processing, low efficiency, high cost, to the spring supply caused some difficulties. Teachers and students of geology school mechanics complied with Chairman Mao’s principle that “schools are factories and factories are schools.” They insisted on the “57th” road and took the initiative to use
