该液压控制系统在双手单次循环模式和全自动模式下的工艺流程为：机器人上料→滑块26快降→预压下行→加压下行→主油缸24保压当滑块26到达设定的工作位置或压力时→主油缸24泄压→脱模→滑块26快速回程→滑块26减速回程→滑块26停止→调平缸顶出到位→机器人下料，至此一个工作循环结束；The process flow of the hydraulic control system in the two-hand single cycle mode and the fully automatic mode is: robot loading → slider 26 drops quickly → pre-pressure goes down → pressurizes goes down → main cylinder 24 maintains pressure when slider 26 reaches the setting When the working position or pressure is → main oil cylinder 24 releases pressure → demoulding → slider 26 returns quickly → slider 26 decelerates return → slider 26 stops → leveling cylinder ejects into place → robot unloads material, and one working cycle ends at this point;
该系统在双手单次循环和全自动模式下的工作原理：How the system works in two-handed single cycle and fully automatic modes:

The electromagnets 3Y1, 3Y2, 3Y4, and 3Y13 are Electrically, the slider 26 moves freely under the action of gravity, and a negative pressure is formed in the rodless cavity of the master cylinder. The filling valve 22 is opened, and the rodless cavity of the master cylinder is automatically filled with liquid. During the movement of the slider 26, it is controlled by motion. The device performs closed-loop control on 3Y4, which can control the system’s rapid drop speed;
当滑块26快进至位滑块移传感器25设定位置时，滑块26由快进转为工作慢进，电磁铁3Y1、3Y2、3Y4、3Y5、3Y43Y13、3Y12、3Y3.2、3Y6、3Y7得电，此时活塞式蓄能器9的油液向系统供油，为了满足设备工艺参数的要求，通过运动控制器算法调节大流量比例插装阀14-4中电磁铁3Y7和小流量高频响比例阀14-5中电磁铁3Y6的控制电压，可实现设备速度域度的调节，同时通过调节主缸有杆腔18-7下腔的下腔大流量比例插装阀18-12的压力，使得滑块26平稳进给。When the slider 26 fast-forwards to the position set by the slider shift sensor 25, the slider 26 changes from fast forward to working slow forward, and the electromagnets 3Y1, 3Y2, 3Y4, 3Y5, 3Y43Y13, 3Y12, 3Y3.2, 3Y6, 3Y7 is powered.

When the liquid level is higher than the high liquid level controller 72 and when the liquid level is lower than the low liquid level controller 73, the hydraulic machine will alarm, prompting a hydraulic machine failure, which is beneficial to protecting the power pump due to oil Deficiency may cause damage; the air filter 74 is used by the fuel tank 1 to filter the inhaled and discharged air to ensure that the air quality of the fuel tank 1 is within the required value range; this process is an independent cooling process and is not affected by the main system.
