The hydraulic press brake is a vital piece of machinery in the sheet metal industry, designed to bend and form workpieces into various shapes according to precise process requirements. This equipment plays a crucial role in ensuring the accuracy and quality of metal components produced in industrial settings.
The hydraulic press brake frame is primarily composed of left and right columns, a worktable, and an upper beam. The left and right oil cylinders are securely fixed to the columns, while the ram, connected to the oil cylinder pistons, moves up and down along the guide rails mounted on the columns. The lower die is fixed to the worktable, and the upper punch is installed at the bottom of the ram. The hydraulic system provides the necessary power, and the electrical system delivers operational instructions. Under the action of the hydraulic cylinders, the slider drives the upper die downward, engaging with the lower die to achieve the bending of the sheet metal.
The left and right columns, worktable, and slider (collectively referred to as the "three major components") are the core elements of the bending machine. Collectively, these components account for 70% to 80% of the total weight of the machine. Their strength and rigidity are critical factors that directly influence the operating precision, machine lifespan, and the accuracy of the workpiece produced. Ensuring the integrity and performance of these components is essential for maintaining the efficiency and reliability of the hydraulic press brake in industrial applications.

1.First, turn on the power, turn on the key switch on the control panel, and then press the oil pump to start (operator can hear the oil pump rotating sounds

2. The stroke adjustment: operator must pay attention to the stroke adjustment, be sure to test running before bending. When the upper punch of the bending machine descends to the lower mold, there must be a gap of plate thickness. Otherwise, it will cause damage to the mold and the machine.

3.For the selection of bending notches on the lower mold, a notch with a width of 8 times the thickness of the plate should generally be selected. If you bend a 4mm sheet, you need to choose a slot of about 32.

4. Back gauge adjustment generally has electric quick adjustment and manual fine adjustment. The method is the same as the shearing machine.

5. Step on the foot switch to start bending. The bending machine is different from the shearing machine. You can release it at any time. When you release your foot, the bending machine will stop, and then step on to continue downward.
