Advanced Aviation Aluminum Profile Hot Press Sinking Mold Hydraulic Press

Specialized hydraulic press
Aircraft aluminum profile hot pressing sinking forming machine
Purpose: The device is suitable for hot pressing and sinking forming of T-shaped aluminum alloy profiles in the field of aviation manufacturing. It is also suitable for processes where alloy materials such as aluminum alloys and titanium alloys have poor formability at room temperature and require heating for stamping forming.
Features: Equipment features: Its main working principle is to heat the mold or parts before forming, so as to increase the overall temperature of the parts, thereby improving the formability of the aluminum alloy, avoiding common defects such as collapse and rupture during the forming sinking process, and reducing rebound.

Detailed process of hydraulic press operation for hot pressing and sinking molds of aviation aluminum profiles:
Preparation before homework
Equipment inspection: Conduct a comprehensive inspection of the mechanical structure, electrical system, and hydraulic system of the hydraulic press to ensure that all components operate normally without any potential faults or hazards.
Mold preparation: Select high-precision hot press sinking molds that match the specifications and shapes of aviation aluminum profiles, clean, install, and debug them to ensure that the molds are firmly installed and positioned accurately.
Material pretreatment: Heat aviation aluminum profiles to a predetermined temperature and ensure uniform temperature distribution to improve material plasticity and forming quality.
Parameter setting: Based on process requirements and the characteristics of aluminum profiles, accurately set key operating parameters such as pressure, stroke, speed, temperature, etc. in the control system of the hydraulic press.
Mold closure
Start the hydraulic press and move the crossbeam downwards under hydraulic drive.
The upper mold gradually approaches the lower mold until it is completely closed, tightly wrapping the aluminum profile inside the mold.
Apply pressure
The hydraulic system gradually increases pressure according to the set pressure curve.
The pressure is evenly applied to the aluminum profile, causing it to start sinking and deforming according to the shape of the mold.
Pressure holding stage
After reaching the set maximum pressure, maintain the pressure for a period of time.
During this period, the molecular structure inside the material is fully adjusted to ensure stable performance and dimensional accuracy of the formed aluminum profile.
Temperature control (if necessary)
Throughout the entire homework process, the temperature of the mold and aluminum profile is precisely controlled through heating and cooling systems.
For example, maintaining a high temperature in the initial stage to promote deformation, and performing appropriate cooling in the later stage of holding pressure to fix the shape.
Pressure release
After the pressure is maintained, slowly reduce the pressure according to the set curve.
To avoid residual stress and dimensional deviation inside aluminum profiles caused by sudden pressure drops.
Mold opening
After the pressure is completely released, the movable crossbeam rises and drives the upper mold to open.
Remove the workpiece
The operator uses specialized tools to carefully remove the aviation aluminum profile workpiece formed by hot pressing and sinking.
Quality inspection
Conduct quality inspections such as dimensional measurement, visual inspection, and internal flaw detection on the extracted workpieces.
Ensure that the workpiece meets the strict quality standards of the aviation industry.
Equipment cleaning and maintenance
Clean up residual aluminum shavings and debris on the mold and workbench.
Lubricate and maintain the key components of the hydraulic press, and check the quality and level of the hydraulic oil.
For example, if uneven deformation of aluminum profiles is found during hot pressing settlement, it may be necessary to adjust the pressure distribution or check the flatness of the mold in a timely manner; For example, if small cracks are found in the workpiece during quality inspection, it may be necessary to re optimize the process parameters or check the quality of the raw materials.
In short, the operation process of advanced aviation aluminum profile hot press sinking hydraulic press requires strict control and precise operation to ensure the production of high-quality aviation aluminum profile workpieces.
