The hydraulic system consists of hydraulic oil tank, hydraulic pump, hydraulic cylinder and solenoid valve, etc. It bends the workpiece to the required angle or shape by providing pressure. Hydraulic press brake is mainly used for precise bending of metal sheets to meet the requirements of metal parts shape in various industrial manufacturing. The equipment can complete the bending task quickly and accurately, greatly improving the production efficiency. At the same time, through precise control and adjustment, the hydraulic press brake can ensure the dimensional accuracy and consistency of the bent product, thereby improving the product quality. Hydraulic press brake plays an important role in the field of metal processing.

This design enables the first rotating shaft 16 to rotate along with the second rotating shaft 45 when the second rotating shaft 45 rotates, so that it can achieve the effect of synchronous adjustment. Then, an I-shaped block 46 is arranged on the outer wall of the second rotating shaft 45, and a plurality of groups of second rotating blocks 44 and first rotating blocks 42 are arranged on the left and right sides of the I-shaped block 46 through a second spring 43 and a first spring 41, which are respectively connected to the first hydraulic block 20 and the second hydraulic block 25. It should be noted here that the second spring 43 and the first spring 41 are tension spring designs, and their main purpose is to pull the first hydraulic block 20 or the second hydraulic block 25 under the action of their own weight. At the same time, their own deformation can make the first hydraulic block 20 or the second hydraulic block 25 slowly descend when sliding downward, which plays a certain protective role. Next, two groups of slide grooves 22 are opened on the left and right sides of the I-shaped block 46, and the third slider 23 and the fourth slider 21 are slidably arranged inside the slide grooves 22. At the same time, the first hydraulic block 20 and the second hydraulic block 25 are respectively fixed on the left and right sides of the I-shaped block 46 through the two groups of second connecting blocks 26 and the first connecting block 24, and the second connecting block 26 and the first connecting block 24 are respectively connected by the first hydraulic block 20 and the second hydraulic block 25. The first slider 17 and the second slider 19 slide in the two groups of second sliders 19 respectively. In the above design, when the I-shaped block 46 rotates 90° clockwise or counterclockwise, the first hydraulic block 20 or the second hydraulic block 25 will move vertically downward and remain stationary under the action of the second spring 43 or the first spring 41, so that the slide groove 22 is aligned with the first through hole 10 on the surface of the second hydraulic plate 25 and the first through hole 10 on the outer wall of the hydraulic plate 12, and then the leveling and fixing are performed by the leveling component 4, thereby completing the hydraulic pressure.
