Slider synchronization control

Machine tool slider synchronous control (Y1, Y2axis),Using German Rexroth/Hoerbigger maleSpecial digitalclosed-loop hydraulic system for bending machines (electronic-Liquid proportional servo synchronous control system), this system is a position control system, which is composed of

① Drive assembly,

② Pressure control valve unit,

③ Closed-loop control It is composed of valve unit,

④ closed-loop proportional valve amplifier,

⑤ hydraulic cylinder,

⑥ position detection system,

⑦ CNC system,

⑧ electrical system, etc. The position synchronization of the two piston cylinders during the stroke process and the positioning of the stroke end point are achieved through an electro-hydraulic synchronous servo system, which has high synchronization accuracy and repeatable positioning accuracy.

It allows the slider to always remain parallel to the workbench during rapid approach, working stroke, end positioning and return. When the slider tilts under various disturbances and unbalanced loads, it dynamically detects the synchronization error of the slider through the grating ruler and feeds it back to the CNC system. The electro-hydraulic servo valve of the CNC system corrects the synchronization error of the slider. It controls the proportional servo valve to adjust parameters such as the flow and pressure of the oil entering the cylinder,so that the two pistons maintain position synchronization, so that the slider and the workbench remain parallel.Single machine slider synchronization accuracy≤±0.05mm.◆Y1, Y2 axes - the left and right sides of the slider are equipped with Spanish FAGOR/Italian GIVI high precision linear grating rulers (Y1-Y2). They are used to measure the exact distance between the slider and the workbench. The grating ruler and the column are made of soft connection so that column deformation does not affect positioning. The position data is immediately fed back to the CNC system, which can then calculate the output servo valve control signal (S1-S2). Therefore, the positioning accuracy of the single machine slider ±0.05mm, the repeatable positioning accuracy of the slider is 0.05mm.

Work bench compensation

Long workpieces will undergo deflection and deformation during the lifting and processing process, making it difficult to guarantee the processing accuracy of the workpiece. In order to ensure that the workpiece meets the processing requirements, a hydraulic compensation workbench is selected
