4. The overall performance of the machine

4.1 Structural steel plate welded structure, strong rigidity.

4.2 Structural parts are derusted by sanding and sprayed with anti-rust paint.

4.3 The column, upper working slide block, and lower working table of the machine tool adopt a large floor boring and milling machine, and use the integral one-time processing method for precision processing to ensure the overall processing accuracy of the machine tool.

4.4 Upward bending design, stable work, convenient operation and safe.

4.5 There is a pressure-holding delay function at the bottom dead center to ensure the accuracy of the workpiece.

4.6 The slider has a large stroke and a high tolerance for parallelism on both sides.

4.7 Under the relevant national standard conditions, the bending angle accuracy can reach ±30'.

4.8 With the function of slow descent control, the operator can better control the workpiece.

4.9 Workbench deflection compensation function ensures bending accuracy.

4.10 The stopper is driven and controlled by a servo motor, which has fast speed, stable transmission, high precision and low noise.

5. Hydraulic system

5.1 Adopt the special synchronous control system of German Rexroth's bending machine, which can obtain higher synchronous control accuracy. The hydraulic system has overload and overflow protection, which is safe and reliable.

5.2 The gear pump used for the oil pump can withstand high pressure and has low noise.

5.3 Cylinder: 45# steel quenching and tempering treatment, inner hole fine boring and grinding.

5.4 Piston: 45# steel quenching and tempering treatment, external high frequency quenching or chrome plating, fine grinding, vibration grinding (super fine grinding).

5.5 The sealing ring is selected from Japan's NOK company, which has good sealing performance, reliable work and long life.

5.6 There is a clear and intuitive display of oil level and temperature.

5.7 The hydraulic system is divided into coarse and fine two-stage filtration, with high filtration accuracy.

6. Electrical control system

6.1 The key electrical components are imported from abroad, which conform to international standards, are safe and reliable, have a long life, and have strong anti-interference ability. The electric control cabinet has a heat dissipation function.

6.2 Movable foot switch operation, with emergency power off function.

7. The function of CNC axis

7.1 The Y1 and Y2 axes are the slider stroke control axes, which are used to control the bending angle.

Two grating rulers (Y1-Y2) are installed at both ends of the machine tool. They are used to determine the exact position of the slider and the worktable; the grating ruler is connected to the worktable so that the deformation of the column will not affect the positioning of the slider. The position data is immediately fed back to the numerical control system, and it can measure and output the servo valve control signal.

7.2 V axis adopts convex control axis (that is, deflection compensation).

Using LVD's unique embossing worktable design and manufacturing technology, a family of ideal embossing curves can be formed, and compensation is achieved over the full length to offset the deformation of the slider and the worktable under stress, and improve the quality of the parts.

7.3 X axis is the backgauge control axis, used to control the flange size of the bending machine.

The X axis uses an imported servo motor to drive the ball screw through a synchronous toothed belt wheel. The two stop jaws are always synchronized during the movement. Smooth transmission, high precision and low noise.

8. Mould

A set of standard upper and lower molds

Standard fixture: Quick clamp

9. Anti-eccentric load capacity of the machine

The power supply servo system of this machine is a position control system. It dynamically detects the synchronization error of the slider through the grating ruler. The electro-hydraulic servo valve signal is given by the numerical control system to correct the synchronization error of the slider, so that the slider is completely deviated. It can always be parallel to the workbench under load.
