　　Product introduction:

　　1. Expansion medium: water. In order to increase the expansion speed, a three-column plunger pump is used to form the head. The equipment is equipped with an automatic pressure return device and can be recycled.

　　2. The maximum pressure of the whole machine: 1500 tons, and the column adopts a steel plate tailor-welded structure.

　　3. Maximum working pressure of hydraulic system: 31.5Mpa, normal working pressure 25-28MPa

　　4. Pressure-maintaining method: The pressure-maintaining method uses an accumulator and a pressure relay to maintain pressure together.

　　5. How the workpiece enters and exits the press: forklift type.

　　6. Workpiece lifting and dropping method: After the workpiece is formed, the workpiece is lifted pneumatically to facilitate the entry and exit of the workpiece.

　　7. Expansive medium recovery method: The air pressure method presses the inflated medium back to the water tank, and the water on the table is pumped back using a water pump.

　　8. Processing head material: carbon steel, stainless steel, aluminum and aluminum alloy.

　　9. The expansion machine uses 24 high-pressure oil cylinders to compress the edge. The oil cylinders require a large amount of oil. In order to ensure the rapid advancement and retreat of the oil cylinders and save the idle stroke time of the oil cylinders, the hydraulic system adopts a high and low pressure dual pump system. Low pressure is used when the oil cylinders advance and retreat during idle strokes. The large-flow pump supplies oil, and the high-pressure pump pressurizes the oil cylinder when it contacts the workpiece, saving the empty stroke time of the oil cylinder.

　　10. Lifting and lowering method of forming blank holder: use the four oil cylinders on the four corners of the press to operate independently to lift and lower the blank holder, so that the blank holder can be pressed in the middle of the steel plate, making it easy to use and operate.

　　11. In order to adapt to the head cross-sections of different specifications, the cylinder is moved using a wrench to drive the chain to move quickly, which is fast and efficient.

　　12. This equipment uses PLC programmable technology to control the actions of each component.

　　13. The height of the expansion head is limited. After the workpiece enters the hydraulic system and builds pressure, with one key operation, the PLC automatically controls water filling, automatically stops water when reaching the height, maintains pressure, returns water, and inflates.
