The effect of blank holder on the deep drawing process on plates using software based with a Finite Element Method (FEM)

Abstract

To reduce product defects in the deep drawing plate process, the manufacturing industry needs to design a product design in the form of initial simulations so as to reduce losses due to design errors. The purpose of this study was to determine the effect of blank holder characteristics on the plates produced in the deep drawing process. The effect of blank holder includes three factors, including: deep drawing without using the holder, clearance, and draw ratio. The simulation in this study uses the Finite Element Method (FEM) method with the help of a computer. The provisions of the part in this simulation with an approximate size setting of 0.25, the material used is steel with a thickness of 0.5 mm and a blank diameter of 51 mm. Cylinder cup diameter 40 mm and depth of formation process 60 mm radius 8 mm and punch force 550 N. Based on the simulation results from the deep drawing process without using blank holders, the force needed for the drawing process will be even greater. While the clearance variable will reduce the force required during the drawing process. And the draw ratio variable gets smaller and will require greater force.
