Designing a deep drawn part requires careful consideration of several factors to ensure that the finished part meets the required specifications. Here are some key steps to follow when designing deep drawn parts:
- Material Selection: Choose a material that is suitable for deep drawing, such as aluminum, steel, copper or brass. The material should have the right combination of strength, ductility and formability.
- Blank Size: Determine the size of the blank metal sheet based on the desired dimensions of the finished part. It’s important to consider the thickness of the material and the amount of deformation that will occur during the deep drawing process.
- Die Design: Create a die that matches the desired shape and dimensions of the finished part. The die should have the right angle and radius to ensure that the metal sheet is drawn into the desired shape without tearing or wrinkling.
- Lubrication: Choose a lubricant that is appropriate for the material being used and the depth of the draw. The lubricant should be applied evenly to prevent sticking and ensure smooth movement of the metal sheet.
- Depth of the Draw: Determine the depth of the draw required to achieve the desired shape. Deep draws require multiple passes through the press with intermediate annealing as needed.
- Finishing Operations: Consider any finishing operations that may be required, such as trimming, punching, or hole-making.
- Design for Manufacturability: Make sure that the design is optimized for manufacturability, taking into account the capabilities of the press and the die materials. Avoid sharp corners and angles, as these can cause tearing and wrinkling during the deep drawing process.
By following these steps, you can design deep drawn parts that meet the required specifications and are optimized for manufacturability.
