2) Main product parameters

Machine Tool Structure This machine is assembled from a frame, slider, workbench, oil cylinder, hydraulic proportional servo system, position detection system, numerical control system and electrical system. The transmission structure of this machine tool is an upward-moving design;

1. The mechanical structure of this machine tool mainly consists of the frame, workbench, slider, main cylinder, and back gauge. Perfect design and manufacturing technology can effectively ensure the manufacturing and use accuracy of machine tools.

2. The rack adopts frame structure, the all-steel overall welded structure eliminates internal stress through normalizing and high-frequency vibration aging to ensure the overall accuracy of the machine tool, has excellent stiffness, and has excellent anti-twisting and anti-tilt capabilities. The thickened worktable and slider make the whole machine highly rigid, so the slider and worktable deform very little during bending, and the workpiece has excellent straightness and angle consistency.

Use a large floor-standing boring and milling machine to perform precision processing using the overall one-time processing method.,   to ensure the overall processing accuracy of the machine tool.

The up and down movement of the slider is controlled by two oil cylinders. The slide synchronization mechanism adopts CNC        electro-  hydraulic servo control synchronization, which is stable and reliable.

Slider synchronization control Machine tool slider synchronous control (Y1, Y2axis),Using German Rexroth/Hoerbigger maleSpecial digital closed-loop hydraulic system for bending machines (electronic-Liquid proportional servo synchronous control system), this system is a position control system, which is composed of Drive assembly,  Pressure control valve unit, Closed-loop control It is composed of valve unit, closed-loop proportional valve amplifier,  hydraulic cylinder,  position detection system, CNC system,  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.
