At present, with the development trend of automobile lightweight, aluminum alloy material is more and more applied in automobiles, among which 2A12 aluminum plate can be used as the material of automobile engine cover. Then 2A12 aluminum plate manufacturer will introduce to you to determine the forming factors of 2A12 aluminum plate automobile engine cover.

The shaping factors of 2A12 aluminum automobile hood mainly include material properties, forming process parameters and die design.In the stamping forming of covering parts, the optimization of technological parameters and die is the main factor to improve the forming quality.

Main influencing factors:

1. Molds have important influence on the forming performance of 2A12 aluminum sheet.Through numerical analysis of possible forming defects and continuous optimization of die surface, the purpose of improving material flow can be achieved so as to reduce forming defects caused by local structure and improve forming quality.

2. Process parameters have significant influence on forming quality.Small blank holder force, large mold clearance, is conducive to ease sheet metal thinning, ensure the precision and strength of parts;Within a certain range, with the increase of the blank holder force, the maximum positive rebound amount of the part decreases slightly, the maximum negative rebound amount increases with the increase of the blank holder force, and the overall rebound amount increases with the increase of the mold clearance.

3. By adjusting compensation and process parameters of 2A12 aluminum plate, the springback of parts can be further reduced.The study of the influence law of forming quality of 2A12 aluminum sheet and the optimization of die surface can be used as the theoretical basis and important reference for practical production.Through the die manufacturing and debugging, the test results verify the stamping forming of the inner plate of the engine hood, which is in good agreement with the simulation optimization results.

The above is the introduction of the shaping factors that determine the 2A12 aluminum plate for automobile engine cover. If you need 2A12 aluminum plate, please consult us.
