Deep Drawing Stamping Aluminum Battery Case

 

 

In the field of new energy vehicles, the application of 3003 aluminum alloy not only improves the energy density and safety of the battery pack but also effectively extends the battery life. Studies have shown that the use of 3003 aluminum alloy can extend the battery life by more than 30%. This is due to its advantages such as high energy density, high safety performance, and long cycle life.

 

 

 

 High strength and good plasticity

 Good corrosion resistance

 Good weldability, poor machinability
 Not suitable for heat treatment strengthening, cold working method is used to improve mechanical properties

 

 

 

Material preparation:

• Select suitable aluminum sheet materials as stamping materials for the battery cell aluminum shell.
• Preliminary processing of purchased raw aluminum materials, such as cleaning and drying.

Mold design and preparation:

• Design a mold suitable for stamping, including upper and lower parts, the upper part is the punch of sheet metal parts, and the lower part is the corresponding die.
• The design of the mold needs to consider the selection of the radius of the punch corner and the friction coefficient of the die, which have a significant impact on the quality of stamping.

Stamping:

• At room temperature, the aluminum material is stamped into the prototype of the battery shell in the mold using a punch press.
• Equipment noise and scrap aluminum scraps may be generated during the stamping process.

Stretching and shearing:

• Stretch the semi-finished products after stamping to achieve the required size and shape.
• Use stretching oil for lubrication to reduce friction and improve production efficiency.
• Shear after stretching to ensure that the finished product meets the specification requirements.

Inspection and packaging:

• Dimensional inspection of stamped parts and unqualified products needs to be eliminated.
• After assembly, simple packaging can be put into storage.
