Design of multi-step dies for sheet metal forming using a workpiece-performance-based approach: A preliminary study [PDF]
MATEC Web of ConferencesDeep-drawn components are predominantly manufactured using multistep operations, e.g., in a progressive or transfer dies. Currently, intermediate die design is geometry-based and often neglects the influence of workpiece plastic flow during forming on ...

Electromagnetic Pulse Assisted Progressive Deep Drawing
, 2014 Cracks frequently occur in conventional cylindrical deep drawing process due to the lower formability of aluminum alloy sheet at room temperature. Therefore, a new approach named electromagnetic pulse assisted progressive deep drawing is proposed in this

Warm-forming of pre-aged Al-Zn-Mg-Cu alloy sheet
Materials & Design, 2020 Aluminium alloys of the 7xxx series are attracting the attention of automakers due to their high specific strength. However, widespread use of 7xxx series alloys for the production of car parts from sheet metal has so far been prevented due to their low ...

The Deep Drawing of a Flanged Square Hole in Thin Stainless Steel Sheet
Metals, 2021 To manufacture metal products of accurate size and shape by deep drawing requires the precise control of a number of variables. The problem of spring-back after the load has to be avoided, and the prevention of cracks in the product requires careful ...

Advanced Engineering Materials, EarlyView.This study demonstrates an efficient recycling route for out‐of‐spec AlSi10Mg atomized powders through compaction and arc remelting followed by suction casting. By correlating compaction load, cooling rate, and resulting microstructure, we show that intermediate pressures (50–80 kN) and rapid cooling refine dendrites, reduce porosity, and enhance ...
