Specialized Hydraulic Press For Aviation Aluminum Profile Hot Pressing And Sinking Forming

Detailed working steps of the hydraulic press for hot pressing and sinking molds of aviation aluminum profiles:
1. Preparation work:
Check the equipment: Ensure that all components of the hydraulic press are functioning properly, including the electrical system, hydraulic system, mechanical components, etc., without any damage, looseness, or leakage.
Mold installation: Install the hot press sinking mold correctly on the hydraulic press workbench, ensuring a firm installation and accurate positioning of the mold.
Material preparation: Place the aviation aluminum profiles preheated to the desired temperature in the mold with accurate positioning.
Set parameters: According to the process requirements, set pressure, stroke, speed, temperature and other parameters in the control system.
2. Start the device:
Turn on the power of the hydraulic press, start the hydraulic system and heating system.
3. Mold closing:
Operate the hydraulic press to lower the movable crossbeam, drive the upper and lower molds to close, and press the aluminum profile between the molds.
4. Pressurization:
The hydraulic system provides high-pressure oil to push the oil cylinder piston, generating strong pressure on the mold, causing the aluminum profile to begin to deform and sink into shape according to the mold shape.
5. Pressure holding:
After reaching the set pressure, maintain the pressure for a period of time to ensure that the aluminum profile is fully deformed and achieves the expected shape and performance.
6. Cooling (if necessary):
If the process requires cooling after forming, start the cooling system to cool the mold and aluminum profile to fix their shape and performance.
7. Pressure relief:
After the pressure maintenance and cooling are completed, slowly release the pressure to gradually reduce the oil pressure inside the cylinder.
8. Mold opening:
Operate the hydraulic press to raise the movable crossbeam and open the mold.
9. Remove the workpiece:
Carefully remove the formed aviation aluminum profile workpiece and check whether its size, shape, and surface quality meet the requirements.
10. Cleaning and maintenance:
Clean up residual aluminum shavings and debris on molds and workbenches, and perform necessary maintenance and upkeep on equipment, such as checking hydraulic oil levels, lubricating components, etc.
It should be noted that throughout the entire work process, operators should closely monitor the operating status of the equipment, such as pressure changes, temperature changes, and the presence of abnormal sounds. At the same time, strictly adhere to operating procedures and safety regulations to ensure the safety and quality of work. Different models and manufacturers of hydraulic presses may have different specific operating steps and details, so it is necessary to read the equipment's user manual and relevant process documents in detail before actual operation.
