Characteristics and structure of hydraulic bending machine

For hydraulic press brakes, peers are not unfamiliar, but for novices, they do not understand. Next, I will explain to you the characteristics of the hydraulic press brake and the knowledge of its structure.

Features of hydraulic press brake:

1. It adopts mechanical block structure, which is stable and reliable.

2. It adopts all-steel welded structure with sufficient strength and rigidity.

3. The slider stroke is motorized and quickly adjusted, manual fine-tuning, and counter display.

4. The slider synchronization mechanism adopts torsion shaft forced synchronization.

5. The wedge-type deflection compensation mechanism ensures high bending accuracy.

6. Hydraulic upper transmission, the oil cylinders at both ends of the machine tool are placed on the slider to directly drive the sliding work.

The structure of hydraulic bending machine:

1. Body

The left and right columns, beams, front and rear supports are welded into an overall frame structure, which has good rigidity and high precision and stability. The upper part of the left and right columns is welded to fix the left and right oil cylinders, and the left and right support bottom angle irons are installed at the lower part of the column to increase the contact area of ​​the bottom and prevent the machine from tipping over during the consignment process. It can be removed after the machine is installed.

2. Slider and stroke adjustment

The slider is made of a whole piece of steel plate. The left and right oil cylinders are placed at both ends of the slider and are connected with the slider through the piston rod. The oil cylinder is fixed on the fuselage. The piston rod is driven by hydraulic pressure to drive the slider to run. There is a mechanical stop to control the position of the slider at the bottom dead center, the motor is adjusted by the stop, the position of the mechanical stop can be adjusted through the worm gear and the worm, and the value is displayed by the stroke counter.

3. Torsion shaft synchronization mechanism

The synchronization of the slider during operation adopts the torsion shaft synchronization mechanism, and the torsion shaft connecting rod is connected with the slider. Simple structure, stable and reliable.

4. Adjusting the front and rear positions of the material stopper on the front support frame and the rear stopper can realize the rear positioning of the workpiece. The position of the material stopper is initially adjusted by the motor through a set of transmission system, and then the precision is fine-tuned by the hand wheel. Its position is displayed by the stroke counter in the button box. If the displayed value does not match the actual measured value, you can pull out the small handle on the left side of the button box and turn it gently to make the displayed value of the counter consistent with the actual size, and then pull out the small handle. out and into the original position. The vertical screw rod is installed on the material stopper, and when the embossed nut is turned, the material stopper rod will move up and down, so that the material stopper rod is flush with the top surface of the lower die.

5. Mould

The upper part of the upper mold is equipped with a connecting plate, and the position of the inclined iron can be adjusted to make the upper mold have a slight curve in the vertical direction to compensate for the deflection generated on the table and the slider when the machine is loaded, which will effectively improve the bending of the work. precision.

6. Hydraulic system

The system can achieve four operating speeds: the slider descends rapidly, the slider descends slowly, closes to work and bends at a slow speed, and quickly returns to the original position.

7. Electrical system

The main electrical components in the electrical system use Delixi products. The electrical box is equipped with various action buttons, and is equipped with a mechanical door lock device, which automatically cuts off the power supply when the electrical box door is opened. After opening the door and power off, note that the main circuit is still energized.

The above is the relevant introduction, I believe that everyone has a certain understanding of the hydraulic bending machine.
