高压水射流切割是一项正在发展中的新技术,由于它具有许多其它切割技术所不能比拟的优点,因此日益受到人们的注意和重视。本文介绍了高压水射流切割的装置和对非金属板材切割试验的情况,得到了射流压力、喷嘴口径、靶距、进给速度与切割深度之间的关系,探讨了高分子聚合物对射流性能的影响。此外,还介绍了对板材进行复杂形状的切割等。 High-pressure water jet cutting is a new technology under development. It has drawn increasing attention and attention because of its advantages unmatched by many other cutting technologies. This paper introduces the device of high pressure water jet cutting and the cutting test of non-metal sheet. The relationship between jet pressure, nozzle diameter, target distance, feed rate and cutting depth is discussed. The effects of polymer on jet performance Impact. In addition, it introduces the cutting of plates in complex shapes.
