1. Structure:
According to JB/T 2257.2-92 "Technical conditions of sheet metal press brake bending machine" and GB/T 14349-93 "Accuracy of sheet metal press brake bending machine", the whole press brake machine design is adopted. Meta-analysis calculation, computer-aided manufacturing (CAD/CAE/CAM) software for structural design, fully guarantee the structural strength and rigidity of each component;
This sheet metal press brake bending machine adopts steel plate welding structure; tempering relieves stress, the sheet metal press brake bending machine has good rigidity and stability; the whole frame has good rigidity, stable work, safe and reliable, and convenient operation; through electrical and The coordinated control of the hydraulic system achieves the ideal bending effect. Through the coordinated control of the special CNC system and hydraulic system of the E21 press brake, the ideal bending effect is achieved.
(1) Slider part of this hydraulic press brake for metal sheet bending adopts hydraulic transmission. The slider part is composed of slider, oil cylinder and mechanical stopper fine adjustment structure. The left and right oil cylinders are fixed on the frame, and the piston (rod) is driven by hydraulic pressure to move the slider up and down, and the mechanical stop is displayed by the E21 control system to adjust the value.
(2) The part of the press brake worktable is operated by the button box in front of the worktable, so that the motor drives the material holder to move forward and backward, and the moving distance is displayed by the E21 digital display.
(3) Synchronization system: The sheet metal press brake bending machine is a mechanical synchronization mechanism composed of torsion shaft and arm. The structure is simple, the performance is stable and reliable, and the synchronization accuracy is high. The mechanical stop is adjusted by the motor, and the E21 controller displays the value.
(4) The material blocking mechanism of this press brake is driven by a motor, and the two screw rods are driven to move synchronously through the sprocket. The E21 controller displays the size of the material blocking, which can be fine-tuned manually.
4.Hydraulic system
(1) The hydraulic valve group adopts Rexroth valve group;
(2). The main motor of this sheet metal press brake bending machine uses well-known domestic brands;
(3) The sealing ring of this press brake machine adopts imported sealing ring, which has good sealing performance, reliable operation and long service life;
(4) Clear and intuitive oil level height and oil temperature display;
(5) The sheet metal press brake bending machine can work continuously under the rated load, the hydraulic system has no leakage and is continuously stable, with high precision.
5.Electrical control system:
(1) The electrical components use Siemens brand;
(2) Equipped with movable foot switch operation, with emergency stop function.
6. Slider synchronization control: Adopt torsion shaft synchronization control.
7. Mold:
The bending mold can be designed and customized according to the actual process requirements of the user.
7. Control system: ESTUN E21
