Warm forming die design, Part III: Design and validation of a warm forming die

Journal of Manufacturing Processes, 2015
Abstract Warm forming is a sheet metal stamping process at elevated temperature that can significantly expand the forming limits of light weight alloys such as aluminum. Most of the work detailed in the literature has been based on a laboratory setting with minimal guidance on how to design warm forming dies for high-volume production. The challenges

Warm-forming practice

Journal of Mechanical Working Technology, 1978
Abstract This paper illustrates the manner in which the combined effects of stress and lubrication affect forming loads within the range of warm- and hot-working temperatures. Graphical results are presented showing how typical parameters such as billet flow stress, coefficient of friction of different commercially-used lubricants, punch pressure in ...

Lubrication for Warm Forming

1976
Tests are described in which graphite substances are used both in ring tests and for the extrusion of thin and thick wall cans at a stock temperature of 800°C. The use of copper plating is examined as a possible protective layer in these operations.

Warm forming of stainless steel sheet

Archives of Civil and Mechanical Engineering, 2010
The aim of warm sheet metal forming processes is to improve plastic flow of material, as well as to decrease the springback effect. This investigation deals with the effect of temperature in the range from 20 °C to 700 °C on basic material parameters of stainless steel sheet metal such as yield stress, ultimate strength, total and uniform elongation ...
