摘要
Abstract
As it is difficult to control the effective forging time of the liquid-air hammer, its dynamics characteristic of the work process was researched, and the sub-time control method was proposed. The liquid-air hammer work process was divided into four continuous stages: drop hammer, hit, bounce and return. For analysis and solving the effective time range of four stages, the dynamic models and differential equations of different stages were established according to the hammer's works. Meanwhile differential equations were solved by Matlab. And samples of four effective time ranges were established on different hit heights and energy. The control system of liquid-air hammer, combined with effective time samples, was redesigned on the Programmable Logic Controller (PLC) and applied to production. The practice proves that this method is feasible for the simplification of some part of mechanical structure of the hammer, and improves operational safety. By more than 5 000 times forging, the system didn't appear any breakdown.关键词
