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 of① 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.
Offset load capacity
Offset loading refers to carrying out load work on the left or right side of the slider. This machine tool has strong anti-eccentric load ability.
Under the action of the eccentric load force, an inclination occurs between the workbench and the slider. The grating detection mechanism located at both ends of the slider detects the deviation and feeds it back to the CNC system. The CNC system controls the electro-hydraulic proportional servo valve to adjust the flow rate entering the cylinder. The amount of oil keeps the two pistons synchronized and maintains a small parallelism error between the worktable and the slider.
If you need to process special parts, you should understand the above-mentioned eccentric load conditions. In general, bias should be avoided load work.
Workbench 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, with the following features:
1. This mechanical compensation workbench has a two-way wavy strip adjustment structure, which can meet the compensation structure of the machine tool in the horizontal and vertical directions;
2. The dense point compensation method is adopted to make the bending accuracy more accurate;
3. The compensation for bending materials with the same plate thickness is in place at one time. Different from the structure of hydraulic compensation that keeps moving back and forth, mechanical compensation greatly reduces the fatigue deformation of the machine tool table and increases its service life;
4. It adopts special reducer and high-precision potentiometer control, and automatically adjusts through the instructions programmed by the CNC system to accurately control the compensation accuracy value.
5. Different from the three-plate structure of the hydraulic compensation workbench, this device adopts a single-plate workbench design, which can effectively prevent interference in the bent workpiece.
CNC back gauge (X)
The X-axis is the front and rear feeding control axis, used to control the bending and flanging size; the servo motor is controlled through the numerical control system DA-53T, and the ball screw is driven to move forward and backward through the synchronous belt; it drives the material girder and the blocking finger to move forward and backward.
The R axis is the upper and lower feeding control axis. According to the processing needs, the back gauge beam can be controlled by the servo motor to move up and down, and the blocking finger can be driven to move up and down.
Ball screws and linear guides are used for transmission to ensure strength while reducing noise; the blocking beams are always synchronized during movement, with smooth transmission, high precision and low noise.
