A Study the Ability to Deep Drawing Process a Square Cup by Finite Element Method
Sanya Kumjing1*, Yanpinit Vachirasurong2 and Papon Somphasong2
Adoption of simulation technology, the ability to draw up a Cup-shaped square 24 x 30 x 20 mm. Material is stainless steel grade SUS430 and SUS304, thickness 2 mm. Using finite elements. In order to obtain the effective stress analysis (Equivalent strain) to the workpiece. So what happened to the discs Blank sheet before the forming by stamping it, there are three types: 1) a rectangular piece of sheet 2) the rectangular pieces and cutting edge is angled 45 degrees 3) pieces of the disc. Found that the square cup stamping steel grade SUS 304, all the part after forming they do not pose a risk of damage to the piece of molding. And for the square cup stamping steel grade SUS 430 with a Blank piece is a rectangle. The workpiece after forming , they do not a risk to damage the piece of molding. Blank piece Stamping with the rectangular pieces cutting edge is angled 45 degrees and the specimen is a disc. It appears that after forming the workpiece, there is a risk of damage to the piece of molding around the curvature radius of the bend. Therefore, it can be concluded that the characteristics of the stainless steel Blank. You should look into the most squares.
