Structure and function of forging hydraulic press

1. Forging hydraulic press consists of main engine, hydraulic transmission system, lubrication system and electrical control system.  

2. There are three operating modes of forging hydraulic press: adjustment, manual and semi-automatic. The operation mode is selected by the change-over switch, and the buttons are controlled centrally.

3. The working modes of forging hydraulic press are: constant pressure pressing and fixed distance pressing.

4. The main body of forging hydraulic press is a prestressed composite frame structure, and the main component is a welded steel plate structure. The pre-tightening of the body adopts hydraulic nut pre-tightening.

5. The slide block is guided by inclined wedge-shaped four-corner octahedral guide rail.

6. The slide block is a three-cylinder pressurization structure with upper transmission, and the slide block and the middle main cylinder block are welded together.

7. The hydraulic system adopts a two-way cartridge valve integrated system.

8. Driving form of hydraulic press: constant power piston pump is directly driven. Eight 250YCY14-1B constant power axial piston pumps are used as the main oil pump of hydraulic system, and CB-B gear pump is used as the cooling and filtering oil pump.

9. The electrical control system is controlled by PLC of Omron Company in Japan.

10. The main cylinder of the slider adopts a 1670T plunger cylinder and two 165T piston cylinders. The piston cylinders return, and the plunger cylinders are sealed with V-ring seals, and the piston cylinders are sealed with Yx-ring seals.

11. The power system of the hydraulic press is placed on the ground, the electric box is placed on the ground, and the operation box is placed on the right front of the machine.

12. The hydraulic press is equipped with a mechanical top-down safety bolt, a photoelectric safety protection device, a safety maintenance platform, a fence, an elevation indicator light at the top, a two-hand operation button at the mobile button station, and an overload protection device and a hydraulic safety support safety loop in the hydraulic system.

13. The hydraulic system is equipped with oil level indicator, oil cooling and filtering system, and water cooling is selected for oil cooling.

14. Slider guide rail is lubricated by concentrated lubrication with thin oil, equipped with oil collecting box, and automatic lubricator is equipped with fault alarm device.
