4m hydraulic bending machine

The 4m hydraulic bending machine includes a support, a workbench and a clamping plate. The workbench is placed on the support. The workbench is composed of a base and a pressing plate. The base is connected with the clamping plate through a hinge. The base is composed of a seat shell, a coil and a cover plate. The coil is placed in the recess of the seat shell, and the top of the recess is covered with a cover plate. When in use, the coil is powered on by the wire, and after being powered on, it generates gravity on the pressing plate, so as to realize the clamping of the thin plate between the pressing plate and the base. Because of the electromagnetic force clamping, the pressing plate can be made into a variety of workpiece requirements, and the workpiece with side wall can be processed

how to use the 4m hydraulic bending machine:

1. First turn on the power supply, turn on the key switch on the control panel, and then press the oil pump to start, so you can hear the sound of the oil pump. (at this time, the machine does not act)

2. Stroke adjustment. Pay attention to adjusting the stroke when using the bending machine, and trial run it before bending. When the upper die of the bending machine goes down to the bottom, it is necessary to make sure that there is a gap of plate thickness. Otherwise, the mold and machine will be damaged. The adjustment of stroke also includes electric speed adjustment and manual stomach adjustment

3. For the selection of bending notch, it is generally necessary to select a notch 8 times the width of the plate thickness. If you bend a 4mm plate, you need to select a notch of about 32

4. The adjustment of the rear stopper generally includes appropriate adjustment of electric speed and manual fine adjustment, and the method is the same as that of the plate shears

5. Press the foot switch to start bending. The bending machine is different from the plate shearing machine. It can be loosened at any time. When the foot is loosened, the bending machine will stop and continue to go down

4 m hydraulic bending machine lifting and installation:

1. The center of gravity of the 4 m hydraulic bending machine is high, and the front is heavy and the rear is light. Therefore, pay attention to the center of gravity position in the lifting, handling and installation process, so as not to cause the machine turnover accident. When lifting, the included angle of the lifting steel wire should be as small as possible to ensure that the accuracy of the machine tool remains unchanged

2. The left and right columns of the 4m hydraulic bending machine are located on the workbench as the benchmark for measuring the level, and the vertical and horizontal directions should be less than or equal to 1000:0.2. Prepare the foundation in advance according to the foundation drawing, install the hydraulic sheet bending machine on the foundation, install the anchor bolts at the same time, and then grout. Tighten the bolts and calibrate the level after the water and mud are all solidified

pressure debugging of 4m hydraulic bending machine:

1. The calculation pressure of 4m hydraulic bending machine is based on the tensile strength of the plate. If your board function is different, although it is calculated to be the same, the force required by practice naturally grows different

2. If the external factors are the same, it is only the problem of the hydraulic bending machine. There are two local adjustments, one is to adjust the tensile strength of the plate in the system, and the other is to adjust the Da value in the system setting

4m hydraulic bending machine structure and characteristics:

1. Adopt all steel welding structure, with sufficient strength and rigidity

2. It is hydraulically driven, and the oil cylinders at both ends of the machine tool are placed on the sliding block to directly drive the sliding work

3. The slider synchronization mechanism adopts torsional shaft forced synchronization

4. Mechanical block structure is adopted, which is stable

5. The motorized speed of the slider stroke is suitable to be adjusted, and it is manually adjusted, and the counter is displayed

6. Wedge deflection compensation mechanism to ensure high bending accuracy
