根据自动线输送工件的要求,我们设计、试制了气-油阻尼缸。这种阻尼缸(附图)是将油缸串联在气缸前面而成,实际上是个双作用、双活塞缸。气缸是主动缸,其二边接口处各装一个速度控制阀(由单向阀和节流阀组合而成)。当5公斤/厘米~2的压缩空气通过二位四通电磁换向阀进入气缸A腔时,由于速度控制阀内的单向阀和节流阀均处于开放状态,压缩空气推动气缸活塞向右移动,气缸B腔内的压缩空气向外排气,但受速度控制阀内单向阀和节流阀处于关闭状态的影响,形成排气节流,减慢了气缸活塞的前
According to the requirements of automatic wire conveying workpieces, we designed and manufactured a gas-oil damping cylinder. This damping cylinder (with photos) is the cylinder in series in front of the cylinder made, in fact, is a double-acting, double-piston cylinder. The cylinder is the master cylinder with a speed control valve (made up of one-way valve and throttle valve) installed at the two sides of the cylinder. When 5 kg / cm ~ 2 of compressed air through the two-way four-way solenoid valve into the cylinder A cavity, because the speed control valve in the check valve and the throttle valve are open, compressed air pushes the cylinder piston to the right Move, the compressed air in cylinder B cavity is exhausted outwardly, but it is influenced by the one-way valve and throttle valve in the speed control valve being closed to form an exhaust throttle, which slows the front of the cylinder piston
