一、研制无冲击高速气缸的目的气缸的使用速度一般最大为500mm/s,然而近年来,由于生产率的提高,主要用于压铸机和塑料成形机取出装置上的气缸,高速化的要求很迫切。作为高速驱动气缸的方法,有使用快速排气阀急剧地从气缸排气,以实现高速化的方法;还有使用两个三通阀,使气缸排气侧的空气比供给侧的空气更快地排出,以实现高速化的方法等。然后,这些方法虽然实现了高速化,但在气缸行程的末端产生的冲击却成了一个大问题。
First, the development of non-impact high-speed cylinder The purpose of the cylinder speed is generally the maximum 500mm / s, but in recent years, due to increased productivity, mainly for the die-casting machine and plastic molding machine take out the device on the cylinder, the speed of the request is urgent . As a method of driving a cylinder at a high speed, there is a method of rapidly exhausting a cylinder with a quick exhaust valve to achieve a higher speed, and two three-way valves are used to make the air on the exhaust side of the cylinder faster than the air on the supply side To discharge, in order to achieve high-speed methods. However, although these methods have been speed-up, the impact at the end of the cylinder stroke has become a big issue.
