Product configuration 

1. All steel structure design, production, beautiful appearance, reliable structure.

2. Using UG (finite element) analysis method, through computer-aided optimization design.

3. The whole steel plate welding structure, vibration aging to eliminate internal stress, so that the fuselage has good strength, stiffness and stability.

4. The left and right columns are welded with bottom plates to fix two oil cylinders. The left and right oil cylinders are arranged at both ends of the slider, and the slider is connected with the oil cylinder through the piston rod, which is driven up and down by the hydraulic system. The worktable is supported by arc cushion block and adjusting cushion plate, and fixed on the column with screws. The lower part of the column is equipped with left and right supporting angle iron to increase the bottom contact area and prevent the inclination during transportation.

5. The whole frame is derusted by sand blasting and sprayed with antirust paint.

Performance characteristics

1. The slider adopts torsion shaft synchronous mechanism, and high-precision taper centering bearing (K-type) is installed at both ends of the torsion shaft, and eccentric adjustment mechanism is installed at the left end, so that the synchronous adjustment of the slider is convenient and reliable.

2. By using the deflection compensation mechanism of the upper die, a specific curve of the upper die can be obtained on the whole length of the machine through adjustment, so as to compensate the deflection of the worktable and the slider when the machine is loaded, and improve the bending accuracy of the workpiece.

3. The angle adjustment is formed by the movement of the mechanical block in the oil cylinder driven by the servo motor, and the value is displayed by snc52 system.

4. Convenient manual lubrication device.
