Hydraulic press brake bending machine

The principle of hydraulic press brake is that it works through electrical Coordinated control with hydraulic system to achieve ideal bending effect. It has a feature of good rigidity and stability. It works smoothly, and is easy to operate. Moreover, it is safe and reliable when processing metals.

1.The main features of the machine

Hydraulic press brake adopts steel plate welding structure; vibration aging eliminates stress, the frame is machined with good rigidity and stability; it works smoothly, is safe and reliable, and is easy to operate; through electrical Coordinated control with hydraulic system to achieve ideal bending effect.

2. The main components and structure of the machine

2.1. Slider part: The hydraulic press brake slider part is composed of a slider, an oil cylinder and a automatically stopper fine-tuning structure. The left and right oil cylinders are fixed on the frame, and the piston (rod) drives the slider to move up and down through hydraulic pressure.

2.2. The working table is composed of a movable working table and a vertical plate, which is processed by a large CNC milling and boring machine.

2.3. Synchronization system: This machine consists of a automatically synchronization composed of a torsion shaft and an arm, with simple structure, stable and reliable performance, and high synchronization accuracy. The automatically stop is adjusted by the motor, and the ESA system displays the value.

2.4. Stopper automation
