When operating the hydraulic sheet metal bending machine, I believe that many friends are very curious about what kind of motion process its bending operation needs to be carried out in order to be specifically operated. In fact, its internal motion process is mainly divided into oil pump startup and downward movement. , bending, and decompression, etc. In this article, the editor will give you a detailed introduction to the movement process of the hydraulic system of the hydraulic sheet metal bending machine, as well as the safety guidelines when operating it. Interested friends can take a look!

The movement process of the hydraulic system of the hydraulic sheet metal bending machine:

Each time a bending action is performed, the typical bending process motion cycle stages of the bending beam on the hydraulic sheet metal bending machine include:

1. Start the oil pump

The motor rotates in the direction marked by the pump arrow, that is, clockwise, to drive the axial piston pump to run, and the oil enters the valve plate and the electromagnetic relief valve through the pipeline and returns to the oil tank. The oil keeps the slider in a fixed position.

2. Downward movement

The rapid downward movement of the hydraulic sheet metal bending machine is produced by the dead weight of the bending machine beam and each accessory and the pressure of the oil. During this process, the rodless cavity of the hydraulic cylinder enters the oil through the filling valve, the rod cavity will generate back pressure, and the oil will return quickly. The fast-forward motion starts from the top dead center, and after a short deceleration stage, the speed of the slider slows down at a certain distance close to the bending sheet.

3. Bending

The bending stage starts from the pressure build-up of the rodless cavity. On the one hand, the bending speed is limited by the oil supply of the oil pump, and on the other hand, it can be adjusted by the proportional valve directional valve. At the same time, the directional valve also controls the synchronous operation of the bending beam and the positioning of the bottom dead center. The limitation of the bending force is accomplished by limiting the pressure of the pump by the proportional relief valve. The corresponding speed, synchronization, positioning and pressure setpoints come from the numerical control.

4. Decompression

The decompression of the rodless cavity starts when it reaches the bottom dead center, or after a short holding time, so that the material has sufficient time to form, and the dimensional accuracy of the part is further improved. The pressure maintaining and decompression are completed by the proportional directional valve according to the instructions of the numerical controller. In order to improve the processing efficiency, the decompression time must be as short as possible, but in order to avoid the unloading shock in the whole system, it is required to prolong the decompression time as much as possible.

Safety guidelines for the operation of hydraulic sheet metal bending machines:

When operating the hydraulic sheet metal bending machine, not only must follow the correct operation method, but also need to follow the safety guidelines. Let's take a look at the introduction of the editor:

1. During the operation, it is not allowed to talk to others, and the spirit must be highly concentrated to prevent people unrelated to the work from entering the work area. Visitors are not allowed to enter the safety white line without permission.

2. After the machine tool of the hydraulic sheet metal bending machine is turned on, any part of the human body shall not enter between the upper and lower molds of the machine tool.

3. Gloves should be worn on both hands during bending operations, but gloves may not be worn when bending is small. When bending, hold the workpiece in place by hand, do not push the work with force, and keep the center of gravity of the body stable.

4. When bending larger workpieces, the bending speed should be slowed down, and any part of the operator's body should not exceed the bending motion range of the workpiece.

5. In case of emergency, press the emergency stop button immediately. On the same machine tool, several dies of different heights cannot be installed at one time. When the machine tool is in use, it is not allowed to perform maintenance on the machine tool.

6. When adjusting or replacing the mold, if you want to put your hand between the upper and lower molds, you must first press the emergency button or turn off the hydraulic motor, then install the upper mold, and then install the lower mold.

The above is the movement process of the hydraulic system of the hydraulic sheet metal bending machine introduced by the editor, as well as the safety guidelines during operation. If you want to know more, you can feel free to consult us!
