Hydraulic flanging machine is divided into straight line and swing according to the movement of the tool holder. The linear structure is relatively simple (such as a door, also known as a door), easy to manufacture, the blade section is rectangular, and the four sides can be used as blades, which is more durable. The tool holder swings around the fixed point and has the advantage of upper part. The lower scissors have small friction and wear, small blade deformation and high cutting precision. The system uses a large flow two-way plug valve as the main oil circuit. No cooler, even if continuous working time is long. Small flow solenoid directional valve controls the oil circuit. Low pressure due to control oil circuit. The flow rate is small, which greatly reduces the failure rate of the electromagnetic directional valve. Although the solenoid valve is still a high pressure oil circuit, the noise and failure rate are significantly reduced because it is only used to adjust the shear Angle and is used much less frequently than the insert valve.

Safety technology and maintenance of hydraulic folding machine:

1. The operator must be familiar with the structure and performance of the shearing machine. The shearing machine is operated by most people at the same time, so there must be a special person to direct the production.

2. Do not put your hand into the upper and lower blades to avoid accidents.

3. Do not put all the sundry tools on the workbench, so as not to get involved in the knife edge and cause accidents.

4. Check the sharpness of the edge regularly. If the knife edge is found dull, it should be promptly ground or replaced. The grinding of the blade requires only the thickness of the grinding blade.

5. Check all parts of the hydraulic flanging machine regularly, keep the machine and the surrounding site clean, and the cable insulation is good.

6. The mesh oil filter installed on the oil suction port of the oil pump should be checked and cleaned frequently to maintain the oil amount of the oil filter. If the oil filter is blocked, the amount of oil is reduced, and the oil pump will be empty, affecting the service life of the oil pump.

7. When the return cylinder pressure is low, the return cylinder can be inflated. The method is: protect the cap and valve cover, install the inflation tool, connect the nitrogen cylinder to the other end of the inflation tool (without oxygen), open the inflation tool, slowly open the nitrogen cylinder stop valve, pay attention to the inflation pressure gauge. At 6.0mpa, close the cylinder stop valve immediately. Close the inflation tool, open the inflation tool, and install the valve cover and protective cap.

8. Check the nitrogen pressure in the return cylinder every three months, and fill nitrogen in time when the pressure is lower than the specified pressure.
